Yes. I am talking about this. A receiving MTA server seems to reject mails from the postfix server on the basis that the "end of DATA part must be terminated with a <CRLF>.<CRLF>". Now I am unsure whether this is caused by postfix or the PHP-Mailer sending to the receiving MTA server via postfix. _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
