I have discovered a problem with the mail sent by cron jobs (I refer only to logs, not invocations of mail from scripts.) They never are delivered. Mar 5 10:32:30 noc5 postfix/sendmail[1175]: fatal: root(0): No recipient addresses found in message header Mar 5 10:32:30 noc5 postfix/sendmail[1175]: fatal: root(0): No recipient addresses found in message header Mar 5 10:37:00 noc5 postfix/sendmail[1268]: fatal: root(0): No recipient addresses found in message header Mar 5 10:37:00 noc5 postfix/sendmail[1268]: fatal: root(0): No recipient addresses found in message header This showed up when I upgraded the system to RELENG_7 yesterday. My previous install was RELENG_7 of May 2, 2009 and it delivered the logs without any problems. No other changes were made. postfix was 2.6.5. I have this same issue on all 8.0 systems I have, but I was blaming a fault in postfix config. Now I realize that this is not the problem. I really don't know quite where to look for this. Any clues would be appreciated. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.

It sounds like cron is trying to spawn something like mail(1) (more likely /usr/sbin/sendmail; would have to look at the code) and passing it either incorrect flags or actual content within the header itself, e.g. a missing To: line. Since postfix is involved, have you verified your /etc/mail configuration to make sure mailwrapper is referring to the correct postfix binaries? The only other thing I can think of would be, possibly, some sort of cronjob root has (either crontab -l or /etc/crontab) which makes use of the MAILTO environment variable. See cron(8) for what I'm talking about. You might have to run cron in debug mode (see -x flag; your argument list will probably be quite long :-) ) to see what it's doing. Otherwise truss or ktrace might be the only way to track down what's going on underneath. -- | Jeremy Chadwick jdc@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
