I have postfix installed and configured on my Mac OS 10.6.3 machines. It works correctly because the unix mail program works fine and sendmail interface can send emails as well. However, I encounter this strange problem. The printing commands, lpr and lp, have the -m switch which sends an e-mail on completion of a print job. This email is not delivered and in /var/log/mail.log I see the following error:
May 7 00:00:04 MacBookPro postfix/sendmail[6309]: fatal: execvp /usr/sbin/postdrop: Operation not permitted May 7 00:00:05 MacBookPro postfix/sendmail[6308]: warning: command "/usr/sbin/postdrop -r" exited with status 1 May 7 00:00:05 MacBookPro postfix/sendmail[6308]: fatal: _lp(26): unable to execute /usr/sbin/postdrop -r: Unknown error: 0 Can someone give me a clue as to what is wrong? Funny thing is that sometimes it starts working on its own and then stops again. Jamal
