David;

Look beyond the error message itself, and you find that the original message comes from... OTRS.  Transferred directly to my internal Exchange server, as it should (and does) do with all OTRS communications.  This communication, apparently from one of the cron job(s) doesn't use correct email addresses.

How can I get the Cron job(s) to not send email to my mail infrastructure?

Thank you,

The message you quoted is an Exchange message, so the problem is there. Exchange (stupidly) has filters for common misconfigurations which are usually not helpful.

OTRS sends mail to root about configuration problems, as root is most likely to be the one that can fix it.

>From the subject line, the message is probably a notification that the OTRS scheduler is not running (just a guess) or that there's a problem fetching new mail. It's probably sending the message to all the OTRS admin ids, which include root by default.
