Having been accomodating about it in the past, the technical geniuses at Comcast have permanently blocked port 25, separating me (at my home office) from my employer's e-mail server. What can be done on the server side to keep Postfix listening on 25 _and_ accept my connections on some other port? Is there a Postfix solution? iptables maybe?
