I'm having a very odd problem with MailMan on this server with a cPanel installation.

I've been troubleshooting a customer's account that claims it "doesn't work" and have narrowed it down to...

If you aren't on the list, you can send e-mail to the list address, and it gets put in the queue for a moderator to delete or accept and post the message.

If you are on the list, nothing happens when you send e-mail to the list address, nobody receives the post, nothing.

Does anyone have any clue how I can resolve this? I'm exhausted.
