No. It has nothing to do with -owner vs. -admin. Mailman never sends to
-admin.

The reason is this.

When an external message is sent to the -owner address, the
scripts/owner script that queues the message to be sent to the owner
specifies the envelope sender by calling
Mailman.Utils.get_site_email(extra='bounces') function which in this
case returns <sitelist>[EMAIL PROTECTED] which in your case
is [EMAIL PROTECTED]

When a message to the owner is created within Mailman it is created as
an instance of the Mailman.Message.OwnerNotification() class which
specifies the envelope sender by calling
Mailman.Utils.get_site_email(mlist.host_name, 'bounces') which returns
<sitelist>[EMAIL PROTECTED] which in your case is
[EMAIL PROTECTED]

Bottom line - external messages to -owner are different from internally
crafted notices to the owner. The former have envelope sender of
<sitelist>-bounces@<the site default email domain> and the latter have
envelope sender of <sitelist>-bounces@<the list's host_name>.

Nothing has changed in the way these messages from Mailman have been
sent. What changed is the host's outgoing SMTP server started
rejecting messages with envelope sender of [EMAIL PROTECTED]
while continuing to accept those with envelope sender of
[EMAIL PROTECTED]

This created a symptom which was highly confusing to say the least.
