Comments on the From: header?

From: Mailer-Daemon
Well, I _believe_ that FROM_DAEMON may be expecting an @ symbol appearing
after the daemon name here (I can't recall ever seeing a daemon message
without an actual address here).
Also this header appears in the middle of the received stream (which makes
me rather suspicious of the received lines appearing after it (possibly
forged), though I don't know if there is anything in RFC822 that prohibits
this ordering).
X-Uidl: 9876543fgt9821376nb0988mm632xx321
As a rule, EVERY message I've ever receieved with an X-UIDL header has been
spam. The presence of this header appears to cause odd actions with the
two big PC-Windows mailers (Eudora Pro and Pegasus). I've had my
suspicions that it is planted in the header for exactly that reason - is
anyone interested in elaborating on this optional header?
