Lisa asked in follow-up,
| If I'm including the | Approved: me@mydomain.com | in the first line of the body (for a moderated list), does it only work if I'm sending | email in plain text?
Yes. Otherwise MIME-wrapping will get in the way ahead of it and it will no longer be at the start of the body.
| Do we need to send out ALL our list emails plain text?
SmartList normally wouldn't require it, but it would be a very good idea on its own merits.
| I think one of the moderators uses AOL set to HTML email.
(S)he can use AOL's webmail to send plain text.
