relays?

I was looking at an online post and am not really sure what a portion
of it means:

I have not seen any responses from php.net on either system. The
cerberusonline.com address is it's own relay. The bowzer.tamu.edu
address sits behind a primary relay, but is a mailhost on its own.

What is a relay in this context? How do I know if an account is its
own relay or if it'd be sitting behind a primary relay? Is gmail.com,
for instance, it's own relay?

Can we get reference to the post to get the context?

I would suspect that relay in this context means that cerberusonline.com
will relay messages from the world to the world presuming that the sending
address is with in the cerberusonline.com domain name. This is in and of
its self a very bad practice, do to the ease of spoofing the from header.

Ugh. I believe that someone is saying "relay" when they should be saying
"server". The server may be forwarding or relaying the messages, but this
is still a server to me. Seeing as how the poster that used that term
seemed to not be an email administrator, this tends to offer credence to
(in such as it does not refute it) the fact that I believe that s/he was
using the wrong term.
