First thoughts would be what error message are they getting?
If they are unable to connect at all to the RaQ then the problem will be a
routing issue with the firewall/masq.
Ask them to make sure the corrects ports are open to send/receive mail.
There should be no setting on your machine (assuming you have no strange
homebrew running) that would prevent someone from at least a simple POP3
check. Might be an issue to send but that is a whole other can of worms.

In other words, if others are able to do it on other domains on the same
machine, they should be able to also. It is obviously a setup/config issue
on their end.

Be Nice, but Be Firm 8-)
