Merely rotating connections within the same /24 subnet isn't going to
help solve your problem. It may in fact make it worse, as you'll start
looking like a snowshoe spammer spreading out his load.

Have you by chance followed Yahoo guidelines yet? If not, doing so will
likely produce far better results than hacking your postfix server(s):

http://help.yahoo.com/l/us/yahoo/mail/postmaster/forms_index.html

This assumes you are sending legitimate email, not spam. Fill out their
bulk sender forms, set up a feedback loop, follow their guidelines, and
you'll likely see your message deferral problem solved.
