In most Postfix versions (everything before 2.10), smtpd_recipient_restrictions controlled relaying. Therefore you must have (as your logs no doubt told you) a restriction which prevents you from being an open relay. Typically this means "reject_unauth_destination". http://www.postfix.org/postconf.5.html#smtpd_recipient_restrictions See also: http://www.postfix.org/SMTPD_ACCESS_README.html -- http://rob0.nodns4.us/ -- system administration and consulting Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:
