Today downloaded sources of version 03.20.09. At the file ForumUtils.vb 2 lines, where called this method

SmtpMail.Send(forumMail) lines 223 and 256

This method not worked at our site, because we defined server IP and login and password.

So it replaced with next lines:

Dim strAttachments As String = ""

Try

For Each strAtt As String In forumMail.Attachments

strAttachments = strAttachments + strAtt + " "

Next

strAttachments = strAttachments.Trim()

Catch ex As Exception

End Try

Dim htHostSettings As Hashtable = DotNetNuke.Entities.Portals.PortalController.GetCurrentPortalSettings().HostSettings

DotNetNuke.Common.SendNotification(forumMail.From, forumMail.To, forumMail.Cc, forumMail.Bcc, Services.Mail.MailPriority.Normal, forumMail.Subject, Services.Mail.MailFormat.Html, forumMail.BodyEncoding, forumMail.Body, strAttachments, CType(htHostSettings("SMTPServer"), String), CType(htHostSettings("SMTPAuthentication"), String), CType(htHostSettings("SMTPUsername"), String), CType(htHostSettings("SMTPPassword"), String))

Now all works fine :)

If you want we can send you updated .dll, but will be good if Forum Core Team public updates ;)
