Hi Mark,

'Tis a good day -- I've learned something new.

Since I still have Wednesday's /var/spool/mail file, I can scan it for
bogus headers.  I've taken a look at the X-UID: lines and they're
properly sequenced (from 859386 to 86199, with increments of 1).

What should I look for to identify counterfeit metadata?

Thanks.

David
