    Send simple EMail

    VS 2005 - XP media - VB .net - winforms - .net 2.0



    Just trying to send an email, here is the code and the error message that I
    get. I can't figure out how to fix it?





    'create the mail message

    Dim mail As New MailMessage()

    Dim smtp As New SmtpClient("htt p://mail.Someplace. com")

    Dim WhatTimeIsIt As DateTime

    mail.From = New MailAddress("To ny@Someplace.co m")

    mail.To.Add("To nyMast@Someplac e.com")

    WhatTimeIsIt = DateTime.Now

    mail.Subject = "This is an email" & Format(WhatTime IsIt) & " - "
    & " winforms"

    mail.Body = "this is a sample body"

    'This next line didn't help error but i was getting error prior to putting
    this line in.

    smtp.Credential s = New Net.NetworkCred ential("Usernam e", "Secrete")

    smtp.Send(mail)

      You don't need HTTP:// in front of the SMTP server, it isn't http, so
      you dont need it :)

          Also, Mcafee and other virus protection programs prevent
          System.Net.Mail and System.Web.Mail from sending emails - it picks
          them up as a mass mailing worm and generates the "Failure sending
          mail" message. Be sure to add them to the list of allowed programs if
          you think it will be a problem.

          Thanks,

          Seth Rowe

              Ok, I kind of got it to work thanks to you guys.
              I can send some emails successfully to 2 servers only (or websites).
              Everything else gives me the error listed below and I know they are good
              addresses.
              I also used bounce@altohiwa y.com and same error (which is a place to test
              email).
              If I go to outlook (same computer same time) I can send to all these email
              addresses without error.

              "Mailbox unavailable. The server response was: <bounce@altohiw ay.comNo
              such user here"}
              System.Net.Mail .SmtpFailedReci pientException'

              Thanks again in advance
