Something that I've run into that you may wish to incorporate into your
HowTo are instructions to fix the mess created after installing an openssl
upgrade.

On my Fedora system the openssl rpm will overwrite the ca-bundle.crt file.
 This wipes out my TLS since I use locally signed cert's that I've added
to the standard ca-bundle.crt file.

The smtp file in /etc/pam.d disappears and is replaced with a postfix-smtp
file.  I have to recreate the smtp file as well as the Sendmail.conf file
in /usr/lib/sasl.  That file is just gone.

As soon as someone complains that their mail client won't send but does
receive mail I know exactly what has happened!

Once I've added the files back I'm in business with SSL enabled
connections and relaying based on auth again.
