Ah.  It was your mail that was being rejected for the sender address
problem (localhost.localdomain) -- I noticed a couple of bounced
messages for that, so I've removed the "sender must be a valid domain"
restriction on the mailing list mail server for now (figuring it's
better people be able to post to ask about the problems).[0][1]

That problem (the sender address being "localhost.localdomain") 
probably also explains why other sites are rejecting your mail too.

This suggests that either:
(a) your sendmail configuration is overriding the from address
    with a default one ("localhost.localdomain"); or 
(b) your hosts file and/or DNS entries aren't set up properly; or
(c) you need to get your mail reader to set the From address (or
    sendmail to let it set the From address).

Somehow who knows RedHat 9 can probably offer more detailed suggestions,
but you may want to check:
- You have an entry for your computer in /etc/hosts which contains
  something sensible

- You have an /etc/mailname file, and it contains something sensible

- Your sendmail.mc file has a "Cw" entry for a sensible domain  (if you
  need to change it, then you'll have to rebuild sendmail.cf file, which
  can usually be done with "make" in /etc/mail.)

- Your mutt configuration has your email address configured, and you may
  want to set "set envelope_from=yes" too (whether that'll work depends
  on exactly how RedHat 9 configures sendmail)

[0] I've been tailing the mail logs all day, and tuning things as I go.

[1] Unfortunately not all mail client/mail server misconfigurations
    can be catered to.  The mailing list mail server will NOT accept 
    mail without a fully qualfied domain in the HELO/EHLO part of the
    SMTP session.  I'm not going to remove this check for RFC2821
    conformance because it's very very successful at keeping the 
    SoBig.F virus out (which gets that wrong).
