Canvas LMS sending emails with Postfix

[Aitor Alvarez]

I am trying to set up Postfix with Canvas LMS and emails don't seem to be going out. I tried Postfix on its own and it sends emails correctly.

My outgoing_mail.yml has the following parameters:

production:

  address: "localhost"

  port: "25"

  domain: "web.com"

  outgoing_address: "mye...@web.com"

  default_name: "Canvas CTI"

  delivery_method: "sendmail"

In my log file in /var/log/maillog nothing gets recorded from Canvas, only the emails that I sent as test from the command line, which makes me believe that there must be a component in Canvas that doesn't connect correctly with Postfix. 

If I go to the web interface, under /jobs I see all the notifications being delayed, with attempts 0/15. If I go to Canvas log file it is almost empty. How can I get more info from Canvas so I can debug this?

Any help would be much appreciated.

Thanks

Is the delayed jobs processor running? "Attempts 0/15" would indicate that it might not be. What does `ps -ef | grep delay` return?

So, looks like it isn't running, then. Which guide did you follow when you were setting up Canvas, Quick Start, or Production Start?

Production start. The emails were working for a while, but since I was using gmail as a relay and there were a lot of emails going out, I thought Google blacklisted my ip, that's why I was trying Postfix. How can I restart the delayed jobs processor?

You can start it up again same way you started it the first time, by running the canvas_init script. https://github.com/instructure/canvas-lms/wiki/Production-Start#automated-jobs

I had the same problem, what I did was:

sudo /etc/init.d/apache2 restart
sudo /etc/init.d/canvas_init stop
sudo /etc/init.d/canvas_init start
sudo /etc/init.d/canvas_init restart

To check if delayed jobs are runing:
sudo /etc/init.d/canvas_init status

You should see something like this:
german@server2:/var/canvas/config$ sudo /etc/init.d/apache2 restart
[ ok ] Restarting apache2 (via systemctl): apache2.service.
german@server2:/var/canvas/config$
german@server2:/var/canvas/config$ sudo /etc/init.d/canvas_init restart
Stopping pool 26182...
Daemonizing...
german@server2:/var/canvas/config$ sudo /etc/init.d/canvas_init status
Delayed jobs running, pool PID: 28911
german@server2:/var/canvas/config$




In the outgoing_mail.yml file I used the following values:

production:
  delivery_method: "sendmail"
  address: "localhost"
  port: "25"
  domain: "mycanvasdomain.com"
  outgoing_address: "nor...@mycanvasdomain.com"
  default_name: "VidaReal Canvas"

Hope this help you
German
