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) Craig --- Cyrus Home Page: http://asg.web.cmu.edu/cyrus Cyrus Wiki/FAQ: http://cyruswiki.andrew.cmu.edu List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
