No, I do not close port 25. It is open because it is an MX host and
other servers can talk to it.

Besides what Paul so nicely explained already, the specific setup with
the MSA allows me to bypass the greet_pause feature and the milters as
being an authenticated relayer. I don't need the virus checking and
spam-tagging for mails leaving my server by authed senders.
