I got some progress on why/when the double-bounce messages get stuck in
It seems to only affect domains that are set to "alias domain" in
Postfixadmin, no one else, and it also looks like all the messages that
gets sent to these addresses gets blocked by reject_rbl_client.
Would it help to move so reject_unverified_recipient is after
reject_rbl_client? But that might not "fix" the issue right?
My smtpd_recipient_restrictions looks like this:
I might have to look into the alias domain section a bit more and see if
I configured something wrong!?
