Am I correct in assuming that spamd and TLS on port 25 don't get along?

Given a mail server (or MUA) that is configured to require TLS on a
port it connects to, it will likely have a problem with any other end
not offering TLS capability. This is hardly spamd-specific.

However, the above is unlikely to be the case. Some sites may attempt
to setup TLS, but IIRC, they only do so if their counterpart
advertises that capability. Note that spamd doesn't advertise that
capability, so there should be no problem.

Capability advertisement takes place after the EHLO stage. I have
never seen any capabilities offered by spamd. It just does what it's
supposed to do (and no more): let valid mail servers through to your
real MTA.

Once the connection passes through to your real MTA, the rules of
engagement for your real MTA apply. By then, spamd is out of the
picture. Upon issuing EHLO to that server, it should return the
supported service extensions.

As a side note: if you intend to let users submit mail, you'd best use
a different port. Ports such as 587 (negotiate STARTTLS) or port 465
(TLS by default). You wouldn't even be dealing with spamd then.
