Thanks Kevin,

The warning in MW indicates "no watermark or sender address" so I think 
I can do a hex dump on the quarantined file and see what's causing the 

I'm still a little confused about having the address whitelisted from 
which these users are sending, and why SA complains since it isn't

I'll keep looking and report if I ever find out what's going on.
