Note that this RHBA had some impact, which was not expected in an RHEL minor
While normally Red Hat reject all updates which can cause a problem with
existing configurations, here in postfix case, this was accepted - surprise...
Example for major impact:
postfix 2.1.5 contains support for database type sdbm, which was suggested to
use for SSL session caching in 2.1.x with TLS support (Red Hat provided such
Provided postfix 2.2.10 misses support of sdbm, btree can be used instead, but
no warning or automagical upgrade of main.cf was done here. As a result, one of
the host I administrate which has a automatic update enabled, upgraded silently
to postfix 2.2.10 and afterwards it could not receive any mail via TLS anymore.
Related error message:

# postconf -m
You find related information in
Main changes with Postfix version 2.2
- Support for CDB, SDBM and NIS+ databases is now built into Postfix
(but the CDB and SDBM libraries are not).
Anyway, I'm happy about supplying a new version and would request the update to
2.2.11 next possible time.
