lots of systems don't accept mail from smtp hosts that don't resolve via
dns - I have no idea if this is your problem or not. You might want to
see if your server/ip_address is listed in some RBL db - try searching
it in the database at www.ordb.org
you can always try to telnet directly to a mail exchanger and conducting
a session interactively to see what it is saying and of course, you can
increase your logging level on sendmail (I believe you can manually edit
to loglevel 15 - by editing the sendmail.cf directly)
