Im looking to use MVCMailer to send emails using asp.net mvc 3 with razor. Also mentioned by ScottHa
It looks fairly straight forward, however i'm confused as to how I would send batch emails eg like a newsletter to a list of users.
do i create a loop around this?
public virtual MailMessage Welcome()
{
var mailMessage = new MailMessage{Subject = "Welcome to MvcMailer"};
mailMessage.To.Add("sohan39#example.com");
ViewBag.Name = "Sohan";
PopulateBody(mailMessage, viewName: "Welcome");
return mailMessage;
}
can someone explain?
thanks
Unfortunately because each email message is personalized, I can't see any other way other than looping. So just change your method to something like:
public virtual MailMessage Welcome(string email, string name)
{
var mailMessage = new MailMessage{Subject = "Welcome to MvcMailer"};
mailMessage.To.Add(email);
ViewBag.Name = name;
PopulateBody(mailMessage, viewName: "Welcome");
return mailMessage;
}
And then call that method inside your loop and send it at the same time.
Important Note
You should setup your web.config to use a pickup directory rather than a SMTP server. Then get IIS to send the email from the pickup directory.
Reasoning - Because you could potentially be calling SmtpClient.Send(MailMessage mailmessage) any number of times - this could become rather expensive if you have to connect to a SMTP server each time to send the email.
A nice side effect of this is you also get some redundancy if the SMTP server is down or unreachable for any reason.
If you want different content for each email, you'll need to create individual MailMessage objects using a loop. If you want the same contents, then you can just add multiple recipients:
mailMessage.To.Add("sohan39#example.com");
mailMessage.To.Add("peter23#example.com");

I'm currently trying to use Selenium Webdriver (C#) to automate a Forgot Password -> Reset Password workflow, where the user navigates to a page and supplies their username, and the backend code validates the username, then sends an email with a reset password link to the email address associated with their account.
I'm able to automate the process up to the point where the code sends the email, but I don't know any ways of checking for the email and/or clicking a link in the email, so I was hoping someone more experienced with Selenium/automation may be able to give me a few pointers.
Ideally the test should not care about the email address that the email is being sent to. Is there a way for Selenium WebDriver or some 3rd party package to catch the email being sent?
Thanks for any input or suggestions.
No. You are talking about setting up an email server, which is not an easy task.
You should send it to a test work email (if this is for a company), or a public email (hotmail/gmail), or if security is not an issue at all, the easiest place to send it would be a disposable email (mailinator)
You could try PutsBox. You can send an email to whatever-you-want#putsbox.com, wait for a few seconds (SMTP stuff ins't instantaneous) then check your email via http://preview.putsbox.com/p/whatever-you-want/last.
Have a look at this post tutorial, it can give you some ideas.
There is no integration of selenium with email clients like Thunderbird/Outlook. But if you have a web interface of the same email client, then you can access the email from browser and using selenium you can read and respond to the emails. I have tried this recently and it works fine where I have used web Outlook for testing.
Hope this helps.
Hi I was in a similar situation and was able to successfully implement a way to get an activation or forgotten password links.
Using Java Mail API I was able to trigger a method when such action is performed which goes into a Folder and read a specific message line then get the link and open it up in a browser using WebDriver.
However the main drawback with this is the inconsistency of reading a specific folder, sometimes emails goes to spam or other folder (in case of Gmail the new Social Folder) making it invisible or difficult to be retrieved.
Overall i think its a process that shouldn't really be automated, In terms of testing it should be done more code base level by mocking responses.
Snippet below should give you an idea on how to go about implementing
public class RefactoredMail {
public static void main(String[] args) {
Properties props = new Properties();
props.setProperty("mail.store.protocol", "imaps");
try {
Session session = Session.getInstance(props, null);
Store store = session.getStore();
store.connect("imap.gmail.com", "username", "password");
Folder inbox = store.getFolder("INBOX");
inbox.open(Folder.READ_ONLY);
Message msg = inbox.getMessage(inbox.getMessageCount());
Address[] in = msg.getFrom();
for (Address address : in) {
System.out.println("FROM:" + address.toString());
}
Multipart mp = (Multipart) msg.getContent();
BodyPart bp = mp.getBodyPart(0);
System.out.println("SENT DATE:" + msg.getSentDate());
System.out.println("SUBJECT:" + msg.getSubject());
System.out.println("CONTENT:" + bp.getContent());
System.out.println("Activation Link:" + ((String)
bp.getContent()).startsWith("http"));
String [] line = new String[1];
line [0] = mp.getContentType().toString();
System.out.println("Activation Link:" + (mp.getBodyPart(0).getLineCount()));
System.out.println("Activation Link:" +line[0]);
} catch (Exception e) {
e.printStackTrace();
}
//WebDriver Stuffs
public String activationUrl() {
//getting the url link and making it a global variable .... etc
//Accessing the link
}
}
You can use https://github.com/cmendible/netDumbster or http://ndumbster.sourceforge.net/default.html. I've used one i forget which. This will host an smtp listener and allow you to make assertions against any email it receives. Its kind of awesome! The caveat is you need to be able to control where the server delivers mail in the environment you are testing.
For every e-mails that my website sends I have it send myself an email as well. I noticed that about 5% of the e-mails (Thousands a day) are being sent twice. The time between the duplicates being sent however is completely inconsistent...Can be a week, a month or a minute. Completely inconsistent...I've tried to debug the issue but I can never duplicate the issue. Always just sends one e-mail and works properly. I'm out of ideas so decided to try and gain some input form the community. Any insight would be greatly appreciated...
public static void SendEmail(string subject, string body, string toAddress, string fromAddress)
{
MailMessage msg = new MailMessage();
msg.From = new MailAddress(fromAddress);
msg.To.Add(new MailAddress(toAddress));
msg.Subject = subject;
msg.Body = body;
msg.IsBodyHtml = false;
using (SmtpClient cli = new SmtpClient())
{
cli.Send(msg);
cli.Dispose();
}
}
Dispose() was just one of my recent attempts that have failed to fix the problem....
And the ascx page that calls the function (note that it is called twice to send it to myslef the first time and the customer the second time if there e-mail address is not null. I did this during testing and decided to leave it in there:
Txp.SendEmail(strOrderConfirmationHeader, strOrderConfirmationText, TxpConst.ORDERNOTIFYADDR, TxpConst.RETURNADDR);
if (!String.IsNullOrWhiteSpace(custemail))
{
Txp.SendEmail(strOrderConfirmationHeader, strOrderConfirmationText, custemail, TxpConst.RETURNADDR);
}
The fact that it's so inconsistent tells me it's probably not the code and it's not the e-mail server cause the mail logs show a completed transaction every time and it gets a different message id every time...I'm all out of ideas!
OK, I'm sure you've already considered this, but are you sure your visitor isn't hitting "submit" twice?
I've seen this many times, particularly when the email server is running a little slowly. User thinks the site isn't doing anything so clicks Submit again. (Or they just double-click the button - seen that too!)
You might just need to put some code your app to guard against multiple submission. It's a fairly common issue.
Hope this helps you.
I'm thinking of implementing "Report a bug/Suggestions" option to my game, however I am not quite sure how I could get that working. I do not have my own server or anything, so I can't just send the text that user has written to there.
The only way I came up with is that the client would write a message and I would send it to an email account where I could read them. However, I do not want that users would need to send the reports through their personal accounts. I am not quite sure how I could implement this and googling didn't bring up any good suggestions.
I haven't done a lot of network stuff, so I'd really appreciate it if you could explain ( possibly even in code ) the process step-by-step.
I am using C# and the game is being programmed for Windows Phone 7.
Yes, it is absolutely possible to do that. From a relatively low-level perspective, you need to:
Resolve the MX (mail-exchanger) server for the e-mail account you want to send to.
Open a socket to the MX server.
Send the appropriate SMTP commands to cause the e-mail message to be delivered to your recipient account. You essentially have the freedom to set the "from" address to be any arbitrary thing you want.
SMTP is a very simple/human-friendly protocol, so it's not a massive effort to do all of that by hand. At the same time, there are prebuilt libraries that will handle all of that for you (except possibly the resolution of the recipient's MX server).
Note that emails sent this way are more likely to be filtered out as spam (generally because the sender's IP/hostname is not going to match whatever domain you put on the outgoing e-mail address you decide to use).
Also note that since you can set the "from" address to anything, you have the option of asking the user if they want to provide their actual contact address, and if they do you can make that the "from" address so that you can actually get back in touch with them if necessary.
You don't need to use email at all. Consider using an error reporting service like sentry or airbrake.
These services have clients that you embed in your program; which automatically log your errors, including any debugging information/stacktrace; and notify you by email when your application reports a problem.
Usually you integrate the app's API into your own error handling mechanism. At the point of an error, the client will capture your debugging information, you can popup a modal asking user for information like "what were you doing when this error happened?", save that as part of your error response that is sent back to the service.
Since the app works over HTTP, you don't need any special ports to be open. It is easier and more helpful than having users send you emails with "it doesn't work!!", and you don't have to deal with email sending headaches.
I recently wrote an article on this: Sending email with C#
You basically have two choices, either you send it using an SMTP-client, this means that you have to have a SMTP-server and be able to connect to port 25 (if you're not using an external SMTP, then you have to manage that by yourself). Or you can use an external email provider, such as:
AlphaMail
SendGrid
Mandrill
If you're using AlphaMail you can send emails in the following way:
IEmailService emailService = new AlphaMailEmailService()
.SetServiceUrl("http://api.amail.io/v1/")
.SetApiToken("YOUR-ACCOUNT-API-TOKEN-HERE");
var person = new Person()
{
Id = 1234,
UserName = "jdoe78",
FirstName = "John",
LastName = "Doe",
DateOfBirth = 1978
};
var response = emailService.Queue(new EmailMessagePayload()
.SetProjectId(12345) // ID of AlphaMail project (determines options, template, etc)
.SetSender(new EmailContact("support#company.com", "from#example.com"))
.SetReceiver(new EmailContact("Joe E. Receiver", "to#example.org"))
.SetBodyObject(person) // Any serializable object
);
Another thing that differs from just building HTML and sending it with an SMTP-client is that with AlphaMail you have the ability to edit your emails outside your code directly in a GUI. You can also easily create highly dynamic templates using AlphaMail's templating language Comlang.
<html>
<body>
<b>Name:</b> <# payload.FirstName " " payload.LastName #><br>
<b>Date of Birth:</b> <# payload.DateOfBirth #><br>
<# if (payload.Id != null) { #>
Sign Up Free!
<# } else { #>
Sign In
<# } #>
</body>
</html>
So this is my thought, why don't you have the email sent to you...as you?
using System.Net;
using System.Net.Mail;
var fromAddress = new MailAddress("from#gmail.com", "From Name"); //Both the email addresses would be yours
var toAddress = new MailAddress("to#example.com", "To Name"); //Both the email addresses would be yours
const string fromPassword = "fromPassword";
const string subject = "There name or whatever";
const string body = "Errors ect....";
var smtp = new SmtpClient
{
Host = "smtp.gmail.com",
Port = 587,
EnableSsl = true,
DeliveryMethod = SmtpDeliveryMethod.Network,
UseDefaultCredentials = false,
Credentials = new NetworkCredential(fromAddress.Address, fromPassword)
};
using (var message = new MailMessage(fromAddress, toAddress)
{
Subject = subject,
Body = body
})
{
smtp.Send(message);
}
code from here
All they would see would be the submit button so they wouldn't have all your personal username/password, also you should prolly set up a dummy account to have them sent to even if it just then forwards them to your real email account.
Another way to achieve this would be to host a WCF Service which takes in your Message and stores in db or /sends email. One downside of this is you'll need a web server to do this.
Try following code this might help you :
Dim objCDOMail
Set objCDOMail = Server.CreateObject("CDONTS.NewMail")
objCDOMail.From = "sender#domain.com"
objCDOMail.To = "receiver#domain.com"
objCDOMail.Subject = "Test Mail Script"
objCDOMail.BodyFormat = 0
objCDOMail.MailFormat = 0
objCDOMail.Body = "Testing Mail from Test Script"
objCDOMail.Importance = 1
objCDOMail.Send
Set objCDOMail = Nothing
I have created a community portal, in which user creates his/her account. After successfull registration a confirmation mail is send on registered email address.
I am using the following code to send the mail -
private void SendMail(string recvr, string recvrName, string verCode, int NewUserID)
{
try
{
string emailID = ConfigurationManager.AppSettings["WebMasterMail"];
string mailPass = ConfigurationManager.AppSettings["pass"];
string mailer = ConfigurationManager.AppSettings["mailer"];
MailMessage msg = new MailMessage();
MailAddress addrFrom = new MailAddress(emailID, "Panbeli.in.... Bari community portal");
MailAddress addrTo = new MailAddress(recvr, recvrName);
msg.To.Add(addrTo);
msg.From = addrFrom;
msg.Subject = "You have registered sucessfully on PanBeli.in.";
msg.Priority = MailPriority.High;
msg.Body = RegisterMessageBody(recvrName, verCode,NewUserID);
msg.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient(mailer);
smtp.Credentials = new System.Net.NetworkCredential(emailID, mailPass);
smtp.Send(msg);
}
catch (Exception Ex) { }
}
While testing we found that all the confirmation mails are going to SPAM folder instead of Inbox.
Is there anything wrong with the code or is there anything related to security.
Can anybody suggest solution to this problem.
Thanks for sharing your time.
It sounds like your email is getting flagged by SpamAssassin or the like, so you just need to focus on changing your email enough to not get flagged.
Your content doesn't sound like it has any reason to rate high for the Bayesian score, so I don't think thats the problem. It wouldn't hurt to try removing possible trigger words though.
Your message is marked with high priority. Do you need this? This just adds into one of the scoring metrics in a spam filter. Spam is often marked with high priority, so your message will be treated with more scrutiny. On the otherhand, for some filters marking your message with high priority will mean less scrutiny.
IsBodyHTML is marked true, but you're only providing text/html. You minimally need to include an alternate view with text/plain.
message.IsBodyHtml = true;
string html = RegisterMessageBodyHtml(recvrName, verCode,NewUserID);
string plain = RegisterMessageBodyPlaintext(recvrName, verCode, NewUserID);
message.AlternateViews.Add(AlternateView.CreateAlternateViewFromString(html, new ContentType("text/html"));
message.AlternateViews.Add(AlternateView.CreateAlternateViewFromString(plain, new ContentType("text/plain"));
See how Google treats your message. In gmail, open a test message that you've sent, click the downfacing arrow next to the reply button, and select "Show Original". You'll see how Google treated your message. Look for headers like:
Received-SPF: softfail (google.com: domain of transitioning xxx#xxx.org does not designate xx.xx.xx.xx as permitted sender) client-ip=xx.xx.xx.xx;
Authentication-Results: mx.google.com; spf=softfail (google.com: domain of transitioning xxx#xxx.org does not designate xx.xx.xx.xx as permitted sender)
Read up on the default rule set for SpamAssassin as it will probably be a good reference on the rule sets for most filters. If you can identify why your message is getting flagged, you can fix it.
Emails Marked as Spam
This is not a programming issue unfortunately, but I can understand why you might think it is. The code is sending the emails, and they have been sent as you reported. So this is highly unlikely to be a problem with your code, because it's served it's purpose fully!
Getting around it
It all comes down to the recipients mail client (the software they are using to view the emails with), or the services that process the emails at some sort of gateway, or a combination of both of these!
All of these elements have vastly varied algorithms and metrics for determining if an email is probably spam or not. So a one fit all solution is sadly not possible. Some are intelligent, other less so, some brutally discard a huge % of emails, others operate purely on a 'not on white list, you're not getting in' policy, and then there are those that just let everything come in regardless of content/origin.
The ways to go around fixing this are:
To try and get on white lists for major email providers.
Educate your audience to add the senders email address as a trusted contact.
Check your mail server IP isn't blacklisted by some providers. It's possible your IP address was previously used to send spam.
Experiment with the emails content
Your from address is invalid. Try putting in a real email address that points to a valid mailbox. Preferably this email address is on the same domain as the SMTP server you use to send the mail with. If not, read into SPF http://en.wikipedia.org/wiki/Sender_Policy_Framework
This happen to me to and it's solved now,
I just set the BodyEncoding and SubjectEncoding proprieties on the MailMessage object,
and added the DOCTYPE and the html tags to my email header,
var msg = new MailMessage
{
Subject = subject,
Body = body,
BodyEncoding = System.Text.Encoding.UTF8,
SubjectEncoding = System.Text.Encoding.Default,
IsBodyHtml = true
};
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
It's working perfectly now
Add following line in your code while creating MailMessage
msg.BodyEncoding = System.Text.Encoding.GetEncoding("utf-8");
This happens a lot even for the house hold names. I sympathise with you as you only want a plain text email but if your clients really want those emails and you really want your logo in then they could just white list your domain so that all emails get through!
We use a company called mailchimp for sending out subscriber mails and I questioned them on how to avoid spam filters especially in the context of essentially an advert out to a large group it can be very difficult to avoid them, here is their advice and there is lots of it.;
Avoiding the Spam Filters
For anyone having this problem, it looks like Google mark as spam any mails using the default ASP.NET e-mail authentication subject and body. I.e.:
"Please confirm your account by clicking here."
Changing the text allows the e-mail to pass the spam filter
I need to send email with attachment. No problem if I do it by myself, but...
Inside the company I work for, I need to pass through a web service awaiting an email and a body.
I know that the implementation of this service use System.Web.mail.Mailmessage doing probably something like this:
MailMessage mm = new MailMessage();
mm.to = email_;
mm.body = body_;
...
So, is there a way to create a string that'll contain my attachement so I can send it to the web service ?
thx.
--Edition--
I must use a class "TheCompanyMail" that has 2 properties (to,body) and one method (send). This class is a proxy to a webservice. This webservice is the one that really sends the mail.
The problem is that I need to add an attachement to the mail and really don't know how to do it.
Example
File f = MyFuturAttachementFile;
TheComapyMail m = new TheCompanyMail();
m.to = "myCustomer#Company.com"
m.body = "Here is the file you're waiting for:"+f.ToString(); //this of course doesn't work !!!
m.send();
So I'm wondering if I can format the string of the body property to add attachement ?
I'm not sure if I'm right, but in my opinion there is no way to pass attachments by adding them in a string to message body. The main why-not argument is safety. I don't think that Microsoft could allow this class to behave like this...
You can't do it that way, you need to add it to the Attachements property of the MailMessage.
Why don't you store the file somewhere else where they can access it and just send them a link to it instead?
You could create an Html email where the "attachment" is actually link to download the file rather than an actual email attachement.
