[Mailman-Users] Upgrading and converting mailman to postfix

[Steven Jones]

Hi,

I have to upgrade a old mailman setup on RHEl3 and sendmail to RHEL6 which comes with postfix by default...

So,  

a) Docs or how easy is it to straight migrate from RHEL3 (2.1.5) to RHEL6  (2.1.12) ?

b) How easy is it to convert a sendmail setup with /etc/aliases to postfix?  any automated scripts?

regards

Steven
