Actually, postfix is not a complete dropin for sendmail. There are a 
number of items it does not do the same way, so if you've got 
extensive configurations and adjustments, there are differences.

I don't disagree postfix is interesting and useful, and has matured 
well. But there are differences in using it.

We do much with modified configurations, we just prefer to rely on 
redhat to port and test the bug fixes on the sendmail binaries, as 
the sendmail.org folks seem to release many releases, and we just 
don't have the bandwidth to track them and rebuild for our servers as 
they come up. You could make the same argument for PHP, Apache and a 
dozen other core application components as "things we should just 
package ourselves" but we might also need a bit of time in our lives 
to run the business, rather than building tools. This is why we pay 
RedHat for bug fixes on our production servers.

In talking with a RedHat person at LinuxWorld, they seemed to be 
getting this feedback from a lot of folks (wanting newer packages, 
supported, on stable versions of RHEL). Sounded like they were open 
to the idea, if not sure how they'd actually implement such.
