ALWAYS pay special attention to ALL ebuild warnings. Not just the ones
from postfix.

Those warnings are there for a reason - it's how devs let you know that
stuff has changed, that the change will make stuff break, and how to
fix or prevent it. They are not there for decoration or fluff.

You should set the ELOG options in make.conf to store these warnings in
some persistent place (log files, mail them, whatever) so you can go
through them at your leisure. 

My usual routine for doing a global update is

emerge -avuND world
conf-update
emerge -av @preserved-rebuild
revdep-rebuild -p -i (then without -p if something is found)
emerge -a --depclean
view portage logs and do what they say
often followed by doing one or more steps again to ensure all is clean

I haven't been adversely hit by an upgrade for over a year now. I put
it down to using the portage tools correctly in the way they were
designed to be used.
