undeliverable mail

[Bill Vermillion]

It's Wed, Dec 20, 2006 at 09:26 . I'm in a small dim room with
doors labeled "Dungeon" and "Forbidden". There is noise, the door
marked Dungeon flies open and Beastie MRA SHOUTS:

> Dear All.

I use the virtusertable in sendmail, and I have my valid addresses,
such as   bv at wjv.com  bv  and then for after that is
a line of   @wjv.com 	nouser.

And nouser is defined in aliases as   nouser:	/dev/null

On one of the mail servers I maintain I just checked and I
had 260,000+ messages routed to "*file*" in the maillog - which
shows up as  mailer=*file*  in the logs.   That maillog rotates
every night at midnight.

Is not really a freebsd-net problem so I removed that from the
reply to line.
