Nope. They work fine. I have several CentOS/RHEL/Fedora mail filters and back-end servers running Postfix built from Simon's source RPMs. You can pick and choose at build-time what options you want (MySQL [vanilla or Red Hat's MySQL even], LDAP, TLS, etc.). I recommend it. For non-mailer systems (i.e. web servers, etc.) I often just install the Red Hat supplied version, but again, the RPMs from Simon work fine there, too. > According to RHEL, they will be on 2.3 until they release 5.4 in Sept. > 09.

If you use Simon's RPMS, and if you keep current, you'll never have to worry about RHEL/CentOS having a newer version than you have, and thus yum won't over-write it. When building a new mail system, I typically get the latest RPM that Simon has available and use it. I'll update a couple of times a year, checking the CHANGELOG and other documentation to make sure I don't get surprised. Be advised: there is one small issue with CDB support and case-sensitivity. He fixed this in (I believe) 2.4, but it got re-introduced in 2.5. In short, older versions of his RPM needed a patch to get CDB support, and that patch created case-sensitive CDB lookups. Later, Postfix included native CDB support, but his RPMs still included the patch to do CDB, and he didn't remove the patch til we discovered the problem. Then, I think that faulty patch got rolled in again in 2.5. Not a big deal - just be aware of it. It's documented in the list archives. --Brian
