Sure; as people have already said, some vendors (cough, Redhat) don't really keep up to date. I haven't checked all their release channels on offer, but the core set of packages only includes Postfix 2.3.3. *And* it doesn't come with mysql/pgsql map support. This is when you go and get the package from the Centos-plus channel and then tell yum to ignore Redhat updates to Postfix so it doesn't clobber your working setup one day...
Typically software coming from the base operating system is not always the one you want to use IF you happen to be in a very specialized environment. For most people postfix 2.3.3 with RHEL will be completely fine for the entire lifetime of that particular server and they most likely won't miss mysql or postgresql support either. ;-) With RHEL you're paying for stability and continuity over a longer time period - not for the latest and greatest snapshot with a specific feature at any point in time. :-) RHEL6, when it eventually arrives, will most likely have a later version of postfix just like RHEL5 (2.3.3) has a more recent version than RHEL4 (2.2.10). See http://www.redhat.com/security/updates/errata/ for info on the life cycle and erratas (updates).
sysadmin sanity. We could produce packaged versions of Postfix from source and put them in our internal repo, but we just don't have the time and resources to keep on top of updates and whatnot.
We do this and have done so for the last 8 years. Kaj -- Kaj J. Niemi <kaj...@basen.net> FI +358 45 63 12000 KSA +966 54 52 43277
