Can you use mailman on a server other than the one where the DNS is pointing to?
Technically there is nothing requiring Mailman to be running on your mail server.
In theory, there is no reason why each address for the mailing list(s) can't be a pop3 mail box that is polled for messages to feed in to Mailman. Though this type of set up is out side of the scope of Mailman. (It would be more in the scope of downloading messages from a mail box and piping them in to standard in of a program.)
I have a website abc123.com and it's hosted on Host A. Host A does not allow Mailman on cpanel. Host B does. I set up a list called "bot@abc123.com" on Host B while also setting up abc123.com as an addon domain. Is there any way to make this work? It doesn't seem to work now even though I have "Remote Mail Exchanger" chosen for the MX value.
Purely from an email administration / routing point of view, you normally don't want the same domain to be handled by multiple servers. (I say normally because there are some special configurations where this is explicitly made to work.)
What you will end up with is each server will only work with (handle email for) it's incomplete list addresses. I.e. host A will not about accounts 1 and 2 but not accounts 3 or 4. Similarly host B will know about accounts 3 and 4 but not accounts 1 or 2.
What would probably be better, as Adam McGreggor suggested, is to have email for the abc123.com domain to one server and have email to the mailing list addresses be forwarded to accounts in a different (sub)domain on the other server. I.e. bot@abc123.com would be forwarded to bot@lists.abc123.com.
