Subject: [IMail Forum] Remote SMTP user cannot authenticateI mail my mail server to relay for local IP addresses only. However, I have a laptop user who authenicates SMTP remotely. Suddenly it won't connect. The message Outlook returns is cannot find SMTP server, but he can receive messages fine. Any idea where to begin? Our firewall is setup correctly, is this some kind of timeout issue?
