Sendmail not working

[alliancesupport]

I just did a fresh install and I'm trying to send an Admin Notification to myself. It says the message was sent but I didn't get it (not in junk mail either).

Where are the logs for this function?

[root]

Check otrs log, maillog and the webserver error log.

I don't see anything related under Admin > System Log.

Where do I find those logs?

your Linux Admin will help you

Ok, I've checked maillog and found that it's failing to send the email:

Oct 31 09:47:13 mycompany-otrs postfix/pickup[38072]: 3E7038119980: uid=48 from=<helpdesk@mycompany.com>

However, according to the documentation here https://otrs.github.io/doc/manual/admin ... tings.html, sending mail should work out of the box so I'm not sure what's wrong. It can fetch emails just fine.

It seems that your firewall and/or the postfix is not set up correctly. Receiving mails ist not the same as sending them.

No OTRS error, just improper setup of your linux system
