Help. I have been using mailman at hostmonster many years. Recently, email delivery to external domains stopped (yes, DNS / SPF/ DKIM/ DMARC all good). Hostmonster says it is a IP address issues Hostmonster - "The emails sent via Mailman use the IP address 127.0.0.1, which is the default IP address of the server. Unfortunately, when emails from this address are dropped due to mailing list restrictions, it becomes challenging to lift these restrictions, thereby preventing us from resolving the Mailman-related issues effectively. " Has anyone else experienced this problem? Is there a solution?
It seems Hostmonster doesn't have a clue about how to support Mailman. Do they use cPanel. Many hosting services use cPanel, and while some do support Mailman, others offer Mailman lists only because they come with cPanel and don't have any interest in actually supporting it.
Mailman delivers mail via an outgoing MTA, most often and by default
this is the MTA listening on localhost (127.0.0.1) port 25. Mailman has
logs smtp
and smtp-failure
that can help diagnose delivery failures
as can information in the MTA's logs. Why the fact that Mailman connects
to the MTA at 127.0.0.1 complicates this in any way is not something I
understand.
Hopefully you can find someone at hostmonster that has a clue.
If this is cPanel mailman, see https://wiki.list.org/DOC/Mailman%20and%20CPanel
