Mark,
I don't think the setup will work, as the client uses O365 for the emails and doesn't appear to like the virtual lists domain on the MM3 server. I've tried both using the O365 email connector as well Smtp2Go, both have the same issue with headers.
real email domain = example.org MM3 virtual domain = lists.example.org
Actually, lists.example.org is a real email domain.
The FROM: header is always what's causing the issue, plus it doesn't like any external emails as it can't send held messages or posts to users outside of the example.org domain.
If you want to use these 3rd party smtp relays, you have to configure them to accept mail from the lists.example.org domain. It should not be difficult, but it is not a Mailman issue. It is strictly an issue with configuring the 3rd party relay to accept the mail.
