abusive signature block

It's that way in Thunderbird and mutt as well.  And elm, and pine,
and...name one--like JP, I've never seen an exception.

However, it -is- fairly easy enough to hack an MTA to add such a message at
the end of every email.  It would be extremely -stupid-, bordering on the
realms of insane, but it's possible.

Actually, it's a smidge harder these days, because you'd need to find
the appropriate block in multipart/alternative MIME messages into which
the message needs to be injected--say, one plaintext in the text/plain
block, and one HTML in the text/html block of the same message.  So it
gets a little more complex than just plopping it onto the end of every
message wholesale, as it would break MIME formatting to do so with a
MIME-encoded message.  That said--still possible, if insane.  You wouldn't
even need to hack the mail transport agent, now I think about it more.
Just write a wrapper that acts as a middleware MTA, and put it in place of
sendmail/postfix/exim or what-have-you, and have -that- hand off to the
real, renamed, MTA binary.  Far easier than hacking into an MTA directly.

</pedantry>
