Actually, as of RHEL6, the default MTA is now Postfix. Sendmail does indeed have a rather lengthy history of vulnerabilities. With that being said, in my opinion, Postfix is also a much more flexible MTA.

Or is it > the typical rant "Sendmail is insecure, see its history"? I don't understand why many people calling sendmail insecure. Sendmail is the default MTA in RHEL, Solaris, AIX, FreeBSD, OpenBSD ... Why should they use an insecure MTA? Sendmail is a very robust and reliable MTA.
