Subject: Re: [otrs] FW: OTRS Scheduler Daemon Cron: MailAccountFetch Look into configuring a real host name for outgoing mail (or rewrite all outgoing headers to user@performair.com) in your MTA configuration. That message usually triggers due to Exchange detecting unconfigured mail servers. 'Root@localhost' is usually a sign of an unconfigured system.

All;

I'm receiving several of the below emails every day.

How can I configure OTRS to either not send whatever this email is, or to send it correctly (i.e. from a proper email address, and to a proper email address)?

This behavior just started a couple days ago, though we've been running OTRS for several months. I upgrade OTRS from 5.0.5 to 5.0.7 last night, but received 4 more of these this morning.

Thank you,

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.

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.

Why is there a piece of OTRS that is trying to send mail to server superuser account? What does this email (from an OTRS daemon) likely indicate?

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.
