Re: [IMail Forum] ISP's blocking port 25 except to their own mail servers

Yes.  'tis true.  You need to either run a port-redirecting utility mentioned in archives, or preferably, put a rule in your firewall to redirect a different external port to internal 25.  Port 587 is generally the recommended external port.

The ISPs; SBC/Yahoo & Ameritech; are blocking port 25. I looked in the list archive and it appears that iMail can only listen on a single port, is this true? I don�t want to force everyone to change to accommodate a few users. It�s easier to have them use their ISP for outgoing mail.     Scott W.
