While the older releases are no longer maintained, and upgrades are
encouraged, it is NOT the case that the older releases are substantially
defective, and do not function as designed.
For 2.3, the only critical patch is the one for CVE-2011-1720, which is
only needed at sites that provide SASL authentication and offer two or
more mechanisms other than PLAIN. Vendor distributions of 2.3.3 should
be patched by now, so if the OP is using the latest vendor update of
this RPM, it should function as designed, and provide a usable set of
features from Postfix 2.3.
An upgrade is only *required*, if the OP needs specific features from
2.4 or later.
