RHEL, IIUC, has EOL'ed 4.5 or thereabouts. Postfix has EOL'ed 2.4.
This poster's platform looks like a house of cards. Everybody stop

And PHP has had approximately three gazillion security issues in the

Exactly. The questions being asked indicate that the poster is well
down on the learning curve to begin with. 15K mails on a clean list
are not that much, and since they are shareholders it's evident that
money is involved.
My recommendation to the OP is to consider outsourcing this. It will
not cost that much, and a reputable email service provider can be
well worth what they charge.
Conversely to do it inhouse I would recommend tearing it all down and
starting over with a recent and well-supported OS. It might look
cheaper on the short-term bottom line to beg on the Internet for help
in keeping the old install running, but when things go wrong, as they
surely will, the costs will skyrocket in ways not yet imagined.
