In was wondering... But then, a lot of email addresses, mine included, sound a bit odd but are from totally legit people. Don't really have the time to moderate posts initially from everyone signing up till I'm satisfied that they are OK... :-(
This doesn't happen too often. Lots of spam gets caught and I (though not so much recently ) just quickly check and discard whatever needs review. Maybe wait and see.
Or if someone knows of any changes to the mailing list host....
