According to this page: http://support.google.com/mail/bin/answer.py?hl=en&answer=13287
GMail does require SSL/TLS.
I'd be interested to see the relevant part of your vb.net code. Are you sure that you are not
doing something like the following - note the last line!
Imports System.Net.Mail
...
Dim SMTPSender As New SmtpClient("smtp.gmail.com")
...
SMTPSender.EnableSsl = True
