The vacation program is utterly stupid.
It will attempt to reply to "<>".
It will attempt to reply to "<MAILER-DAEMON>" (some stupid hosts
don't put in the "@domain" in the brokets, as they are required
to by RFC822 -- I leave it to your imagination to determine which
ones).
If it's not a UNIX mailbox delivery (i.e., there is no "From "), it
ignores the header "From: ".
Here are my patches to fix this, since it has recently become
obnoxious (patches follow .sig).
!@#@$@! Frigging ancient piece of code...
