An ode to Postfix and Dovecot on RHEL

I would still be spending hundreds of dollars a month on Google Workspace if I
had not transitioned to running my own email server in 2022.  This is the best
decision I've made in a long time.  I've continuously improved this system since
then and it's now in the best incarnation, which is Postfix and Dovecot on Red
Hat Enterprise Linux, running on a server in my IT closet.

Postfix consists of a combination of server programs that run in the background,
and client programs that are invoked by user programs or by system
administrators.

The Postfix core consists of several dozen server programs that run in the
background, each handling one specific aspect of email delivery. Examples are
the SMTP server, the scheduler, the address rewriter, and the local delivery
server. For damage-control purposes, most server programs run with fixed reduced
privileges, and terminate voluntarily after processing a limited number of
requests. To conserve system resources, most server programs terminate when they
become idle.

Client programs run outside the Postfix core. They interact with Postfix server
programs through mail delivery instructions in the user's ~/.forward file, and
through small "gate" programs to submit mail or to request queue status
information.

Other programs provide administrative support to start or stop Postfix, query
status information, manipulate the queue, or to examine or update its
configuration files. 

Dovecot is an open source IMAP and POP3 email server for Linux/UNIX-like
systems, written with security primarily in mind. Dovecot is an excellent choice
for both small and large installations. It’s fast, simple to set up, requires
no special administration and it uses very little memory.

I am running my web server and email server on the same machine.  In the future,
I will transition the web server to its own system and leave this machine just
running email.  It's amazing value for money.

This feels like a flex but I don't tech well enough to understand it.

Not a flex, just a gesture of appreciation.  My I.T. closet is a shrine to free
software!
