ASMTP works on the premise of "we can relay mail for you if we can authenticate you with certain credentials" Adding the IP to "hosts we can relay mail for" negates the need to authenticate, IMHO. So I am still waiting for how MM3 does ASMTP. Does it?
If by ASMTP, you mean SMTP AUTH, Mailman does it if smtp_user: and smtp_pass: are provided in mailman.cfg.
I agree that an authenticated user should be able to submit mail to be relayed. Just guessing here, but perhaps the issue is the OP is submitting to the deprecated port 465 instead of 587.
Port 465 is not quite depreciated. It's the decision of the Admin to decide to listen on/and accept SMTP AUTH on which port. On the servers I run, and based on Exim as the MTA, I accept SMTP AUTH On ports 465, 587 and 2525 (this is meant to subvert some ISPs!). But let's await Roland's response.
The server runs power-mailinabox, which uses Postfix indeed. All my mail, and quite a few others' mail is sent from the using SMTP-Auth on port 465. Actually, this message is sent via that server too. So it's clear to me that MM3 is not authenticating for some reason.
