I had an issue where I was getting CDO.Message excpetions in my log and not recieving notifications about new threads.  I tracked the problem down to the fact there is no SMTP auth code in the SendForumMail function in the ForumUtils.vb file.  If you use SMTP auth on your email server you will need to include this code right below this line:

If Not Len(_portalSettings.HostSettings("SMTPServer")) = 0 Then
SmtpMail.SmtpServer = CType(_portalSettings.HostSettings("SMTPServer"), String)
End If

You need to enter this:

Not sure why they don't use the dotnetnuke sendemail function.  Hope that helps someone.  I would be glad to provide the compiled dll to anyone that needs it.  Just respond to this thread. 

HI,

I don't have the source code version of the Forum and am struggling to get e-mail notification working within the forum.  Did you ever look to see if the code used the core DNN send mail functions or are the lines above needed to send authenticated SMTP mail ?   I am using version 3.20.08 of the Forum on site version on 04.03.07 of Dotnetnuke framework.

Hi Chris,

I think thnk there is missing the Notification funktion in the forum setting.  There is only standard forum and not notification forum to aktivate in the forum settings.  That I am missing too, since the last versions. I hope that is availible in the next upcomming version of the forum module.  I am wait already completely hot for it.

Regards

Matthias
