Emailing from VB.NET APP
Posted on 2006-03-27
I have a problem sending emails from my vb.net program. It is fine sending to email address's on our domain, but doesn't work if I try and send to an external address e.g. hotmail account. No error is reported, the email is just never recieved.
Code is as follows:
Dim Message As New System.Web.Mail.MailMessage
.To = "<firstname.lastname@example.org>"
.From = "<email@example.com>"
.Body = "My test mail"
.Subject = "My subject"
Dim MailServer As System.Web.Mail.SmtpMail
MailServer.SmtpServer = "555.555.555.5" 'IP of my exchange server (version 5.5 sp2)
Any help would be great
