I have it working fine.  I recently replaced a very old implementation
of sendmail and Mailman on Solaris with a new one on CentOS 6.  When I
did so, I used the POSTFIX_ALIAS_CMD mechanism to automatically process
the aliases.  See: 

In mm_cfg.py:
     POSTFIX_ALIAS_CMD = '/usr/bin/sudo /etc/mail/import-mailman-aliases'
/etc/mail/import-mailman-aliases contains:
     #! /bin/sh
     /bin/cp /etc/mailman/aliases /etc/mail/mailman.aliases
In /etc/sudoers.d/mailman:
     Cmnd_Alias IMPORT_MAILMAN_ALIASES = /etc/mail/import-mailman-aliases
     Defaults!IMPORT_MAILMAN_ALIASES !requiretty
In the sendmail.mc file I changed:
     define(`ALIAS_FILE', `/etc/aliases')dnl
     define(`ALIAS_FILE', `/etc/aliases,/etc/mail/mailman.aliases')dnl
so that the Mailman aliases would be in a separate file.

Warning: You need to have Mailman 2.1.15 or better (or patch it).
See this bug: https://bugs.launchpad.net/mailman/+bug/266408.
A fix is here: 
(Thanks to Mark Sapiro)

I stayed with sendmail because I am using LDAP for aliases and routing and I 
did not want to figure out how to do it with Postfix.  My one exposure to 
Postfix was a disaster trying to fix the email services on our marketing 
department's web server at a hosting provider that did not support sendmail. 
Perhaps with time, I could have made it work for our mail server, but the 
duckling syndrome may have set in (yes, I still use vi and sometimes ed).
