I'm very new to the ASP.NET C# area. I'm planning to send a mail through ASP.NET C# and this is the SMTP address from my ISP:
smtp-proxy.tm.net.my
Below is what I tried to do, but failed.
<%# Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="SendMail" %>
<html>
<head id="Head1" runat="server"><title>Email Test Page</title></head>
<body>
<form id="form1" runat="server">
Message to: <asp:TextBox ID="txtTo" runat="server" /><br>
Message from: <asp:TextBox ID="txtFrom" runat="server" /><br>
Subject: <asp:TextBox ID="txtSubject" runat="server" /><br>
Message Body:<br>
<asp:TextBox ID="txtBody" runat="server" Height="171px" TextMode="MultiLine" Width="270px" /><br>
<asp:Button ID="Btn_SendMail" runat="server" onclick="Btn_SendMail_Click" Text="Send Email" /><br>
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
</form>
</body>
</html>
And below is my code-behind:
using System;
using System.Web.UI.WebControls;
using System.Net.Mail;
public partial class SendMail : System.Web.UI.Page
{
protected void Btn_SendMail_Click(object sender, EventArgs e)
{
MailMessage mailObj = new MailMessage(
txtFrom.Text, txtTo.Text, txtSubject.Text, txtBody.Text);
SmtpClient SMTPServer = new SmtpClient("127.0.0.1");
try
{
SMTPServer.Send(mailObj);
}
catch (Exception ex)
{
Label1.Text = ex.ToString();
}
}
}
PS: I'm sorry that I couldn't understand the receiver/sender SMTP concept, and so I am trying to understand the whole concept from here.
Just go through the below code.
SmtpClient smtpClient = new SmtpClient("mail.MyWebsiteDomainName.com", 25);
smtpClient.Credentials = new System.Net.NetworkCredential("info#MyWebsiteDomainName.com", "myIDPassword");
// smtpClient.UseDefaultCredentials = true; // uncomment if you don't want to use the network credentials
smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
smtpClient.EnableSsl = true;
MailMessage mail = new MailMessage();
//Setting From , To and CC
mail.From = new MailAddress("info#MyWebsiteDomainName", "MyWeb Site");
mail.To.Add(new MailAddress("info#MyWebsiteDomainName"));
mail.CC.Add(new MailAddress("MyEmailID#gmail.com"));
smtpClient.Send(mail);
Try using this code instead. Note: In the "from address" give your correct email id and password.
protected void btn_send_Click(object sender, EventArgs e)
{
System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();
mail.To.Add("to gmail address");
mail.From = new MailAddress("from gmail address", "Email head", System.Text.Encoding.UTF8);
mail.Subject = "This mail is send from asp.net application";
mail.SubjectEncoding = System.Text.Encoding.UTF8;
mail.Body = "This is Email Body Text";
mail.BodyEncoding = System.Text.Encoding.UTF8;
mail.IsBodyHtml = true;
mail.Priority = MailPriority.High;
SmtpClient client = new SmtpClient();
client.Credentials = new System.Net.NetworkCredential("from gmail address", "your gmail account password");
client.Port = 587;
client.Host = "smtp.gmail.com";
client.EnableSsl = true;
try
{
client.Send(mail);
Page.RegisterStartupScript("UserMsg", "<script>alert('Successfully Send...');if(alert){ window.location='SendMail.aspx';}</script>");
}
catch (Exception ex)
{
Exception ex2 = ex;
string errorMessage = string.Empty;
while (ex2 != null)
{
errorMessage += ex2.ToString();
ex2 = ex2.InnerException;
}
Page.RegisterStartupScript("UserMsg", "<script>alert('Sending Failed...');if(alert){ window.location='SendMail.aspx';}</script>");
}
}
You can try this using hotmail like this:-
MailMessage o = new MailMessage("From", "To","Subject", "Body");
NetworkCredential netCred= new NetworkCredential("Sender Email","Sender Password");
SmtpClient smtpobj= new SmtpClient("smtp.live.com", 587);
smtpobj.EnableSsl = true;
smtpobj.Credentials = netCred;
smtpobj.Send(o);
Try the following :
try
{
var fromEmailAddress = ConfigurationManager.AppSettings["FromEmailAddress"].ToString();
var fromEmailDisplayName = ConfigurationManager.AppSettings["FromEmailDisplayName"].ToString();
var fromEmailPassword = ConfigurationManager.AppSettings["FromEmailPassword"].ToString();
var smtpHost = ConfigurationManager.AppSettings["SMTPHost"].ToString();
var smtpPort = ConfigurationManager.AppSettings["SMTPPort"].ToString();
string body = "Your registration has been done successfully. Thank you.";
MailMessage message = new MailMessage(new MailAddress(fromEmailAddress, fromEmailDisplayName), new MailAddress(ud.LoginId, ud.FullName));
message.Subject = "Thank You For Your Registration";
message.IsBodyHtml = true;
message.Body = body;
var client = new SmtpClient();
client.Credentials = new NetworkCredential(fromEmailAddress, fromEmailPassword);
client.Host = smtpHost;
client.EnableSsl = true;
client.Port = !string.IsNullOrEmpty(smtpPort) ? Convert.ToInt32(smtpPort) : 0;
client.Send(message);
}
catch (Exception ex)
{
throw (new Exception("Mail send failed to loginId " + ud.LoginId + ", though registration done."));
}
And then in you web.config add the following in between
<!--Email Config-->
<add key="FromEmailAddress" value="sender emailaddress"/>
<add key="FromEmailDisplayName" value="Display Name"/>
<add key="FromEmailPassword" value="sender Password"/>
<add key="SMTPHost" value="smtp-proxy.tm.net.my"/>
<add key="SMTPPort" value="smptp Port"/>
You can try MailKit
MailKit is an Open Source cross-platform .NET mail-client library that is based on MimeKit and optimized for mobile devices. You can use easily in your application.You can download from here.
MimeMessage mailMessage = new MimeMessage();
mailMessage.From.Add(new MailboxAddress(fromName, from#address.com));
mailMessage.Sender = new MailboxAddress(senderName, sender#address.com);
mailMessage.To.Add(new MailboxAddress(emailid, emailid));
mailMessage.Subject = subject;
mailMessage.ReplyTo.Add(new MailboxAddress(replyToAddress));
mailMessage.Subject = subject;
var builder = new BodyBuilder();
builder.TextBody = "Hello There";
try
{
using (var smtpClient = new SmtpClient())
{
smtpClient.Connect("HostName", "Port", MailKit.Security.SecureSocketOptions.None);
smtpClient.Authenticate("user#name.com", "password");
smtpClient.Send(mailMessage);
Console.WriteLine("Success");
}
}
catch (SmtpCommandException ex)
{
Console.WriteLine(ex.ToString());
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}

if your are using gmail please enable secure app. using this link

If you want to generate your email bodies in razor, you can use Mailzory. Also, you can download the nuget package from here.
// template path
var viewPath = Path.Combine("Views/Emails", "hello.cshtml");
// read the content of template and pass it to the Email constructor
var template = File.ReadAllText(viewPath);
var email = new Email(template);
// set ViewBag properties
email.ViewBag.Name = "Johnny";
email.ViewBag.Content = "Mailzory Is Funny";
// send email
var task = email.SendAsync("mailzory#outlook.com", "subject");
task.Wait()
According to this :
SmtpClient and its network of types are poorly designed, we strongly
recommend you use https://github.com/jstedfast/MailKit and
https://github.com/jstedfast/MimeKit instead.
Reference : https://learn.microsoft.com/en-us/dotnet/api/system.net.mail.smtpclient?view=netframework-4.8
It's better to use MailKit to send emails :
var message = new MimeMessage ();
message.From.Add (new MailboxAddress ("Joey Tribbiani", "joey#friends.com"));
message.To.Add (new MailboxAddress ("Mrs. Chanandler Bong", "chandler#friends.com"));
message.Subject = "How you doin'?";
message.Body = new TextPart ("plain") {
Text = #"Hey Chandler,
I just wanted to let you know that Monica and I were going to go play some paintball, you in?
-- Joey"
};
using (var client = new SmtpClient ()) {
// For demo-purposes, accept all SSL certificates (in case the server supports STARTTLS)
client.ServerCertificateValidationCallback = (s,c,h,e) => true;
client.Connect ("smtp.friends.com", 587, false);
// Note: only needed if the SMTP server requires authentication
client.Authenticate ("joey", "password");
client.Send (message);
client.Disconnect (true);
}
Google may block sign-in attempts from some apps or devices that do not use modern security standards. Since these apps and devices are easier to break into, blocking them helps keep your account safer.
Some examples of apps that do not support the latest security standards include:
The Mail app on your iPhone or iPad with iOS 6 or below
The Mail app on your Windows phone preceding the 8.1 release
Some Desktop mail clients like Microsoft Outlook and Mozilla Thunderbird
Therefore, you have to enable Less Secure Sign-In (or Less secure app access) in your google account.
After sign into a google account, go to:
https://www.google.com/settings/security/lesssecureapps
or
https://myaccount.google.com/lesssecureapps
In C#, you can use the following code:
MimeMessage message = new MimeMessage();
BodyBuilder Attachmint = new BodyBuilder();
message.From.Add(new MailboxAddress("name sender", "Mail From"));
message.To.Add(MailboxAddress.Parse("Mail To"));
message.Subject = Subject;
message.Body = new TextPart("plain")
{
Text = tex_body.Text + Massage
};
Attachmint.Attachments.Add("Attatchment Path");
message.Body = Attachmint.ToMessageBody();
SmtpClient client = new SmtpClient();
client.Connect("smtp.gmail.com", 465, true);
client.Authenticate("Mail from", "Password mail");
client.Send(message);
you can send mail from Gmail to Private Mail As X#PrivetCompany.com

In my Email Template :
<img src="/mysite.com/image/logo.png"/>
Any help would be appreciated.
Outlook web access will block any images by default - only if the user chooses to display/download images these will be displayed/downloaded. I am not sure if it is possible to adjust the default behavior by using office 365 admincenter or the OWA settings.
Some time ago it was possible to work around this by using it as a background image inside a table>tr>td cell background-image css property.
EDIT
Checked a recent project of myself, where we are sending notification mails about tickets. The site logo is displayed correctly in outlook/owa - without adding the recipient to the trusted list:
using (MailMessage mm = new MailMessage(sender, header.RecipientAddress, header.Subject, header.Body))
{
mm.Body = header.Body;
mm.BodyEncoding = Encoding.UTF8;
mm.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure;
mm.Priority = priority == IntMailPriority.High ? MailPriority.High : MailPriority.Normal;
mm.IsBodyHtml = bodyIsHtml;
// logo
if (bodyIsHtml)
{
AlternateView htmlView = AlternateView.CreateAlternateViewFromString(header.Body, Encoding.UTF8, "text/html");
string logoPath = $"{AppDomain.CurrentDomain.BaseDirectory}\\images\\logo_XXX.png";
LinkedResource siteLogo = new LinkedResource(logoPath)
{
ContentId = "logoId"
};
htmlView.LinkedResources.Add(siteLogo);
mm.AlternateViews.Add(htmlView);
}
// create smtpclient
SmtpClient smtpClient = new SmtpClient(smtpSettings.ServerAddress, smtpSettings.Port)
{
Timeout = 30000,
DeliveryMethod = SmtpDeliveryMethod.Network
};
// set relevant smtpclient settings
if (smtpSettings.UseTlsSsl)
{
smtpClient.EnableSsl = true;
// needed for invalid certificates
ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };
}
if (smtpSettings.UseAuth)
{
smtpClient.UseDefaultCredentials = false;
NetworkCredential smtpAuth = new NetworkCredential { UserName = smtpSettings.Username, Password = smtpSettings.Password };
smtpClient.Credentials = smtpAuth;
}
smtpClient.Timeout = smtpSettings.SendingTimeout * 1000;
// finally sent mail \o/ :)
try
{
smtpClient.Send(mm);
}
catch (SmtpException exc)
{
throw new ProgramException(exc, exc.Message);
}
catch (InvalidOperationException exc)
{
throw new ProgramException(exc, exc.Message);
}
catch (AuthenticationException exc)
{
throw new ProgramException(exc, exc.Message);
}
}
Afterwards the logo is referred to as
<IMG alt="Intex Logo" src="cid:logoId">
inside the generated html.
I want to create a table for these strings and send it via email the problem is that these string are array which may have multiple values and i can't use loop inside string.

I was hoping someone would be able to help me, I'm trying to send an email from a noreply idea to a people in a company email domain, but it keeps using my personal email instead. Here is my code, maybe I'm missing something.

// GET: Home
public ActionResult Index()
{
return View();
}
[HttpPost]
public ActionResult Index(MailModel model, List<HttpPostedFileBase> attachments)

using (MailMessage mm = new MailMessage(model.To, model.To))
{
mm.Subject = model.Subject;
mm.Body = model.Body;
foreach (HttpPostedFileBase attachment in attachments)
{
if (attachment != null)
{
string fileName = Path.GetFileName(attachment.FileName);
mm.Attachments.Add(new Attachment(attachment.InputStream, fileName));
}
}
mm.IsBodyHtml = false;
SmtpClient smtp = new SmtpClient();
Console.WriteLine("smtp : " + smtp);
smtp.Host = "10.12.6.12";

smtp.Send(mm);
Console.WriteLine("mm : " + mm);
ViewBag.Message = "Email has been sent.";
var emailService = new IdentityConfig.EmailService();

};
emailService.Send(msg);
}
return View("Index");

You create an instance of the MailMessage class with model.To for both sender and receiver. The first one should be the email of the sender:
using (MailMessage mm = new MailMessage(model.From, model.To)) { }
Also, check out the link in the comment by Hans Kesting.
I have seen so many solutions tried each one of them, but none of them are working for my case.
I tried below points but none of them worked unfortunately.
https://www.google.com/settings/security/lesssecureapps Turned in on
UseDefaultCredentials = false; Didn't work either
https://support.google.com/mail/answer/1173270?hl=en Turned step 2 verification on generated an app password didn't work either
Can someone help me to figure it out...

i have been trying to figure out how to send outlook email via C# to multiple recipients. For now i can do a loop among the recipients, but there is going to a lot of sent emails in my sent box.
Microsoft.Office.Interop.Outlook.Application oApp = new Microsoft.Office.Interop.Outlook.Application();
Microsoft.Office.Interop.Outlook.MailItem oMsg = (Microsoft.Office.Interop.Outlook.MailItem)oApp.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem);
oMsg.HTMLBody ="test";
oMsg.Subject = "test" ;
Microsoft.Office.Interop.Outlook.Recipients oRecips = (Microsoft.Office.Interop.Outlook.Recipients)oMsg.Recipients;
Microsoft.Office.Interop.Outlook.Recipient oRecip = (Microsoft.Office.Interop.Outlook.Recipient)oRecips.Add("xxx#xxx.com");
oRecip.Resolve();
oMsg.Send();
oRecip = null;
oRecips = null;
oMsg = null;
oApp = null;
If i add multiple address to it like:
(Microsoft.Office.Interop.Outlook.Recipient)oRecips.Add("xxx#xxx.com,yyy#yyy.com,zzz#zzz.com")
This will not work somehow. Can anyone help me on this?
You just need to separate each user by a semicolon. For example look at my code below.
Outlook.MailItem mail = null;
Outlook.Application objApp = new Outlook.Application();
mail=(Outlook.MailItem)objApp.CreateItem(Outlook.OlItemType.olMailItem);
mail.Subject ="HI";
mail.To = "personone#yahoo.com; Persontwo#yahoo.com";
mail.Attachments.Add("C:\SOME_FOLDER\SomeFile");
mail.Body="xxxxxx";
mail.Send();
("xxx#example.com,yyy#example.org,zzz#meta.example.com") isn't the divider a semi-colon as in
("xxx#example.com; yyy#example.org; zzz#meta.example.com") ??
If I go into my Outlook and send to multiple people it's a semi-colon displayed in the to: field.
Why not just call "oRecips.Add" for each recipient? After all it's ADDING to the RECIPIENTS...?
EDIT: Just verified:
Microsoft.Office.Interop.Outlook.Application oApp = new Microsoft.Office.Interop.Outlook.Application();
Microsoft.Office.Interop.Outlook.MailItem oMsg = (Microsoft.Office.Interop.Outlook.MailItem)oApp.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem);
oMsg.HTMLBody = "test";
oMsg.Subject = "test";
Microsoft.Office.Interop.Outlook.Recipients oRecips = (Microsoft.Office.Interop.Outlook.Recipients)oMsg.Recipients;
foreach (var recipient in new string[] { "a#b.c", "c#d.e" })
{
Microsoft.Office.Interop.Outlook.Recipient oRecip = (Microsoft.Office.Interop.Outlook.Recipient)oRecips.Add(recipient);
oRecip.Resolve();
}
oRecips = null;
oMsg.Send();
oMsg = null;
oApp = null;
will create ONE sent item with any number of recipients, just like I thought.
This code is working fine for sending multiple recipients
private static void SendMail(string body){
try { string tomail = System.Configuration.ConfigurationManager.AppSettings["ToMailString"];
string[] allToAddresses = tomail.Split(";,".ToCharArray(), StringSplitOptions.RemoveEmptyEntries);

//Microsoft.Office.Interop.Outlook.MailItem tempItem = (Microsoft.Office.Interop.Outlook.MailItem)Globals.ThisAddIn.Application.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem);
Microsoft.Office.Interop.Outlook.MailItem email = (Microsoft.Office.Interop.Outlook.MailItem)(oApp.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem));
email.Subject = "Status Report";
email.Body = body;
Microsoft.Office.Interop.Outlook.Recipients oRecips = (Microsoft.Office.Interop.Outlook.Recipients)email.Recipients;
int mailcount1 = 1;
for (; mailcount1 < allToAddresses.Length; mailcount1++)
{
if (allToAddresses[mailcount1].Trim() != "")
{
//email.Recipients.Add(allToAddresses[mailcount1]);
Microsoft.Office.Interop.Outlook.Recipient oRecip = (Microsoft.Office.Interop.Outlook.Recipient)oRecips.Add(allToAddresses[mailcount1]);
oRecip.Resolve();
}
}
oRecips = null;
((Microsoft.Office.Interop.Outlook.MailItem)email).Send();
Console.WriteLine("Mail Sent");
}
catch (Exception ex)
