Are there standard solutions for dealing with the obvious collision

will say to use SMTP AUTH but right now I want to try to get my current
setup to work. My first idea was to hack the pop-before-smtp Perl
script to have the thing (daemon) add connecting/authenticating sender
IPs to a pf whitelist table. I'm running OpenBSD 4.2 (stable) with
Postfix 2.5.
Why not use port 587 to send mail, instead of port 25, and only allow
SMTP Auth from this port.
