This isn't a postfix group, but...

The main reasons (abbreviated) I switched from sendmail 8.11.x to postfix:

1) built in header/body checks that go off  regexp/pcre
2) human-understandable configuration files (no .mc/.cf madness)
3) performance that puts sendmail to shame
4) advanced UCE hooks
5) complete replacement for sendmail

After the switch, even more reasons that it was a good move:

1) great community support
2) code is maintained and actively developed/improved
3) MTA is extremely robust and reliable
4) updates are painless and error-free
5) I could go on

Did I mention that is works wonderfully with mailman? :-)  My mail list 
server was the first one to experiment with postfix.  The results were so 
good that I moved all other smtp servers over a month or two later.
