My intention is to send a mail from c# using outlook interop library.But the problem is the prod machine won't have outlook software installed in it.
Is ther a way to send mail using c# without outlook installed?
Even if it is intalled, will it require an account to be configured?
3.Can we specify the from address manually instead of accessing the outlook account?
Note: I am not going to use SMTP based email because the sent mails will not sync with the mail server.
Thanks
yes this is possible using C# alone.
user does not need to install outlook in client machine.
C# provides a namespace called System.Net.Mail. This has all the classes required to send a mail from C#. It does not have any dependency with OutLook.
Have a look below code snippet :
System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
message.To.Add("jeet#abc.come");
message.Subject = "This is the Subject line";
message.From = new System.Net.Mail.MailAddress("From#XYZ");
message.Body = "This is the message body";
System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient("**yoursmtphost**");
smtp.Send(message);
In place of "yoursmtphost" you can configure the Ip address of machine as well.
Hope this solves your query. Don't forget to mark answered if done.
You can easily use Gmail free SMTP Server and send Mail using your Gmail account :
System.Net.Mail MailMessage message = new System.Net.Mail.MailMessage();
message.To.Add("yourfriend#yahoo.com");
message.Subject = "subject";
message.From = new System.Net.Mail.MailAddress("yourgmailaccount#gmail.com");
message.Body = "body";
System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient("smtp.gmail.com", 587);
smtp.Credentials = new System.Net.NetworkCredential("yourgmailaccount#gmail.com", "yourgmailpassword");
smtp.EnableSsl = true;
smtp.Send(message);

I am given a task to create a new smtp mail server which can receive mail using C#.
While going through the articles i read we can send emails via SMTP but we have to receive or read using POP.
I was directed to links by some stackoverflow already existing questions:
Rnwood and sourceforge
Rnwood I am sorry but i did not understand how to use it.
source forge the msi asked to download if we run it, it asks to download framework 1.1.4322 which will not install in my system and throw error.
Usually there are codes for sending messages so I tried msdn example
I used localhost as the server and 587 as the port.
which gives me error (for any port 587,25)
I also found an article here which actually monitors the localhost and specified port when I try to run the msdn code.
But still I am unable to send email to test in any way.
So is there any way I can code to set up smtp in my own server and receive email and test.
Setting up and configuring a mail server is a completely different ball game than just sending or reading emails from an existing IMAP / POP3 server.
A mail server consists of a number of components such as:
A Mail Transfer Agent (MTA) that handles SMTP traffic and which is responsible for sending email from your users to an external MTA and to receive email from an external MTA.
Mail Delivery Agent which retrieves mail from the MTA and places it in the recipient's mailbox.
A domain name with appropriate DNS records and an SSL certificate.
A server that provides IMAP / POP3 functionality.
In short... stick to publicly available mail servers...
In your post you referenced the SmtpClient from the .NET framework. That library is used to connect to an existing mail server. You can use it like this.
MailMessage message = new MailMessage();
message.From = new MailAddress("your.email.address#example.com", "Your name");
MailAddress recipientsMailAddress = new MailAddress("the.recipients.email#example.com");
message.To.Add(recipientsMailAddress);
message.Subject = "The subject of your email";
message.Body = "The body / content of your email";
message.IsBodyHtml = false; // You can set this to true if the body of your email contains HTML
SmtpClient smtpClient = new SmtpClient
{
Credentials = new NetworkCredential("Your username/email", "Your password"),
EnableSsl = true, // Will be required by most mail servers
Host = "The host name of the mail server", //
Port = 465 // The port number of the mail server
};
smtpClient.Send(message);
If you have a Gmail account, you can use their SMTP server in your C# application, simply use these settings and it should all work.
Hostname: smtp.gmail.com
Port: 587
Username: your_email#gmail.com
Password: ********
RequireSSL: true
Have a look at SmtpListener, I think it does what you want.
It isn't a standard email server which will receive new emails throught SMTP, store them on disk and allow you to retrieve them using POP.
SmtpListener will create a SMTP server that will receive email and allow you to react to any new email through code.
However, please note that you will have to configure it in your production environment like a real SMTP server, including MX DNS entries.
i have WPF application with send mail function.
SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587);
NetworkCredential basicCredential = new NetworkCredential("user_name", "password");
smtp.Credentials = basicCredential;
smtp.EnableSsl = true;
smtp.Send(mail);
i noticed that McAfee antivirus bloks the SMTP mail by default and only after modifing McAfee configuration "prevent mass mailing worms from sending mail" property to false i could send email. is there any email account that will not be blocked with any antivirus without any configuration modification (Yahoo maybe...)?
I had the same issue and I'm afraid the only way of overcoming this is by applying a rule to your AV to allow emails sent from within your application. At least this is what I have done in the past since I couldn't find any other way.
I want to send email using the SMTP client in C#. Currently I am using this code:
System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
message.To.Add("receiver");
message.Subject = "";
message.From = new System.Net.Mail.MailAddress("sender");
message.Body = "This is a test mail";
System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient("smtp.gmail.com");
smtp.Credentials = new System.Net.NetworkCredential("username", "password");
smtp.Port = 587;
smtp.EnableSsl = true;
smtp.Send(message);
But I want to send mail with out using username and password by just providing the sender address. Is this possible in C#?
Is this possible with any SMTP server(Not google). I mean login to server anonymously and just provide your mail address.
No. Gmail does not allow anonymous senders. Thankfully.
If it was possible anyone could pretend to send emails from everyone else, rendering gmail as one big spam engine.
It depends on your server. In your code you are using Gmail and Gmail requires this.
You can set up your own SMTP server.
The SMTP server in IIS allows this per default if your application is on the same server as IIS.
In the end you'll have to send credentials if the server demands them.
You could send the credentials of the current security context if that's what you're looking for. See: http://msdn.microsoft.com/en-us/library/system.net.credentialcache.defaultnetworkcredentials.aspx.
I set up my hMailServer on my windows 2008 machine, and I'm trying to send emails.
When I do it with C#
MailMessage message = new MailMessage();
message.From = new MailAddress(from, "John");
message.To.Add(new MailAddress(to));
message.Subject = subject;
message.Body = body;
SmtpClient client = new SmtpClient("mail.example.com");
client.Credentials = new System.Net.NetworkCredential("john#example.com", "password");
client.Send(message);
But when I try to send emails with a windows live email client, it gives me an error
The connection to the server has failed
All the settings are exactly the same. I tried several email clients, but it doesn't work. It never happened to me before. I just moved from one machine to another, and got this problem.
I can receive mail in the client though...
Try to telnet to port 25, can it connect?
Open up command prompt:
telnet mail.example.com 25
If it cannot connect (which is what I expect) then you have a problem that is not code related but firewall related. (Or perhaps you're trying to connect to the wrong port if they're running SMTP on a non standard port)
I am trying to send email using Exchange 2007 from a console app using the following code and I get this error message in the exception that gets thrown on the Send call.
The SMTP server requires a secure
connection or the client was not
authenticated. The server response
was: 5.7.1 Client was not
authenticated
MailMessage message = new MailMessage();
message.From = new MailAddress("from#example.com");
message.To.Add("to#domain.com");
message.Subject = "test";
SmtpClient smtp = new SmtpClient(ConfigurationUtil.SMTPServer);
smtp.Credentials = new System.Net.NetworkCredential("from#example.com", "password");
smtp.Send(message);
This worked on Exchange 2003.
This ended up being an Exchange 2007 issue and had nothing to do with code.
From the error message it seems like you need to connect to Exchange via SSL.
SmtpClient smtp = new SmtpClient(ConfigurationUtil.SMTPServer, 465);
Substitute that port number for the port that your Exchange server's secure connection is listening on.
