Question

SmtpClient emailClient = new SmtpClient(MailServer);
System.Net.NetworkCredential SMTPUserInfo = new System.Net.NetworkCredential(sender_mail_id(organisation mail id), pwd);
emailClient.UseDefaultCredentials = false;
emailClient.Credentials = SMTPUserInfo;

emailClient.Port = 587;
emailClient.Send(msg);

Above code for sending mail is working. I would like to configure my own port (my outlook outgoing server port) ie instead of 587. How to do that? (My organisation outlook id is attached with yahoo id)

Answer 1

Here is something that you can use to follow for example use it anyway you like to fit your example

    MailMessage mailMsg = new MailMessage();
    mailMsg.To.Add("[e-mail]");
    // From
    MailAddress mailAddress = new MailAddress("[e-mail]");
    mailMsg.From = mailAddress;

    // Subject and Body
    mailMsg.Subject = "subject";
    mailMsg.Body = "body";

    // Init SmtpClient and send on port 587
    SmtpClient emailClient = new SmtpClient("mailserver", 587);
    System.Net.NetworkCredential credentials = new System.Net.NetworkCredential("username", "password");
    emailClient.Credentials = credentials;
    emailClient.Send(mailMsg);
