Why do I have problem sending Email to external servers

Discussion in 'Site Programming, Development and Design' started by Micah, Feb 28, 2017.

  1. I have developed an ASP.NET webforms application. I'm trying to send a form filled to an internal account and then a copy to the email account of the user. I dont get any errors. Internal mails are sent while external emails dont get sent. I also noticed I could not send email from a some of my email accounts to external emails like gmail or yahoo, from even an email client application

    Here is the line of code :

    SmtpClient smtpClient = new SmtpClient("mail.domainhost.co.uk",25);
    NetworkCredential credentials = new NetworkCredential("userName", "password");
    smtpClient.Credentials = credentials;

    MailMessage mailMessage = new MailMessage(FromAddress,ToAddress,Enquiry,Message);
    mailMessage.Priority = MailPriority.High;
    int i = 0;
    i = 1;
    catch(Exception e)
    i = 0;
    return i;

    Can I get help with this please?
  2. I am having a very similar problem. Were you ever able to resolve this?

    When supplying SMTP authentication, make sure you use the full email address and password to that email address.
