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?

I have had similar problems with some of my hosting clients. We configured postfix to also listen on port 2525 as follows:

RFC 2476 defines port 587 as the preferred port. http://www.ietf.org/rfc/rfc2476.txt
