[Mailman-Users] Strange behavior with Outlook+Exchange

[Odhiambo Washington]

I have a client who is facing a problem unseen before.
She's been using MS Outlook to send mail to a Newsletter managed by Mailman.

It's all been good, using Approved:Password as the very first line to send
her newsletters using Outlook - until we added an Exchange account.
Now, when she sends the Newsletter, the below error is returned and the
message rejected by Mailman:

-----Original Message-----
From: Newsletter [mailto:listname-bounces at lists.domain.name] On Behalf Of
listname-owner at lists.domain.name
Sent: Tuesday, April 02, 2019 6:48 PM
To: Jane Doe
Subject: Monthly Newsletter

Message rejected.
It appears that this message contains an HTML part with the
Approved: password line, but due to the way it is coded in the HTML it
can't be safely removed.
----- End Original Message----



I am debating with myself whether it is necessary to adjust any changes
related to message composition within Outlook, or make a change
within Mailman config to accommodate the issue.
