Upon closer examination:  Your initial posts all had From: header
address set to "beartooth at adelphia.net".  Your most-recent post's From: 
header differed only in lettercase, being "Beartooth at adelphia.net".

Believe it or not, Mailman's considering these two forms to be distinct
addresses is _not_ a programming error:  There are many mail systems
where the lettercase of usernames is significant.  (The same is not true
of Internet hostnames.  Thus, strings to the right of the "@" symbol
_are_, correctly, treated by Mailman as case-insensitive.)

Anyhow, that explains what happened -- in case you were wondering what I
was talking about, concerning "a posting address not subscribed to this
list".  You should beware of uppercasing normally-lowercase usernames, I
think, as the unexpected may sometimes happen in various places, not
just e-mail.
