Recipient address rejected: User unknown in local recipient table

[Jorge León]

Hi.

I just found out this group exists and i wanted to ask if any of you guys have faced this problem before:

550 5.1.1 <x...@xxx.com>: Recipient address rejected: User unknown in local recipient table

Suddenly, outgoing email stopped working and that's what i can see under the "Jobs" section of the Admin Settings.

We have another Canvas site with the same SMTP credentials and it's working ok.

I don't think that is a canvas problem, it is a problem with the upstream relay, most likely.

I just found out those are old errors.

My Canvas server hasn't been sending emails since Sept 23rd and i didn't change anything in the config files.

I don't even know where the log file is. I have tried with canvas_init restart, restarting the whole server, re-checking the outgoing_mail.yml is correctly setup, and re-checking the delayed jobs service is started. None of this work, and i have another Canvas server with the same config and it works.

Logs are in the `log` directory under your canvas installation. Mail is usually sent as a delayed job, so you'll want to check out that logfile first, and/or the https://yourcanvas/jobs page. production.log (or development.log, if you're running RAILS_ENV=development) can be helpful as well.

Thank you... The logs of the delayed jobs actually show the same as the Jobs page in the Admin Settings.

Email is not going out

:(

As Shawn said, this sounds like a mailserver issue, not a Canvas issue. Canvas is sending your messages; your mailserver is rejecting them.

Can you post a redacted version of outgoing_mail.yml?
