AOL intercepts all port 25 connections and reroutes them through their own mail servers. How nice of them.. A work around is to setup a port redirect on your mail server using a high port like 2555 and redirect it to 25. Then change your settings in outlook to use port 2555.
Check out the port mapper at www.analogx.com When you get that setup you can use firedaemon to make port mapper run as a service. http://www.firedaemon.com/ Korey Verlsteffen Network Administrator WebStream Internet Solutions [EMAIL PROTECTED] http://www.webstream.net (888) 932-2333 Toll-Free (954) 730-7127 Local (954) 733-7067 Fax (954) 730-7405 Help Desk ----- Original Message ----- From: "Owen Grabo" <[EMAIL PROTECTED]> To: "IMail_Forum@list. ipswitch. com" <[EMAIL PROTECTED]> Sent: Tuesday, June 18, 2002 12:07 PM Subject: [IMail Forum] SMTP errors through AOL > I've been having some very strange problems trying to send mail through > our IMail server via an AOL connection.
