When you send mail originating outside Mailman to the listname-owner
address it is ultimately delivered to Postfix from Mailman for the
owner/moderator recipients in exactly the same way as a Mailman
generated notice.

There are a few differences in the headers of the message ultimately
sent to the owner/moderator recipients and of course, the bodies are
different (but you could test manually sending a copy of an actual

The major difference is the From: header which in the cast of the
message you send has hour address and in the case of the notice has
the listname-owner address. The notice also has headers like

Precedence: bulk
X-BeenThere: listname at example.com
X-Mailman-Version: ...
List-Id: ...
X-List-Administrivia: yes

that probably aren't in the manually generated message.

Perhaps the issue is that there is spam filtering in the local network
that discards Precedence: bulk messages destined for local recipients.
