That really depends if you want the extra functionality Amavisd-new
offers. For example, do you want to be able to quarantine spam/viruses
or simply tag them as such and leave it for the end user to filter in
their inbox? (although I suspect there's many ways to implement a
quarantine other than amavisd).

I don't see much relevance in what upstream does, but FWIW the default
MTA in RHEL6 is now Postfix. Dovecot is a sensible choice and integrates
well with Postfix. rpmforge has an updated amavisd/SA/ClamAV stack
that's generally very reliable for production use.
I run Postfix/Dovecot with Amavisd-new/SA/Clam on el5 and am more than
happy with that setup, but there are many ways to skin this particular
cat and much will depend on your own personal preference.
