[Mimedefang] Multiple From addresses

today I recieved a SPAM that puzzled me, because it displayed _two_
addresses in the From: field. Checking the log that was caused by a
malformed From: line as the comment part didn't quoted the comma; so I
checked RFC822 sec 4.4.1, where the plural is used, hence, it is legal to
specify multiple From addresses.
However, I grepped all mails I got hands on and found NO single valid mail
with two From addresses, hence, it's a SPAM indicator; does anyone
stumbled across a valid mail with multiple From's, perhaps, someone uses
this "feature" himself?
