Hi Steve,

another question related to this topic: How can I change the email backend? django-sendmail-backend [0] should does this job. But adding EMAIL_BACKEND = 'django_sendmail_backend.backends.EmailBackend' to /usr/lib/python3/dist-packages/lava_scheduler_app/settings.py has no effect. Lava still try to send an email via smtp.

[0] django-sendmail-backend

Regards, Matthias

Hi Frank,

my Debian machine running lava-server (2019.04) sends mails via msmtp/ msmtp-mta. Mails from cron or apt work fine. But I got no mails from lava. Even when I submit a test job with a notify statement.

The user default uses my real mail address not a system mail address.

This is the Django log:

Lava has a problem with smtp. Is it necessary to have a complete smtp server on the local machine? Or is there a special smtp configuration?

LAVA expects to use a local MTA of some sort. If you have msmtp installed, then that should do the job as far as I know. Does it have any logs to show what's going on?

My *first* guess would be that you might need to specifically configure things to allow the "lavaserver" user to send mail. For example,

https://wiki.archlinux.org/index.php/Msmtp

talks about per-user config.

The log files mail.(err|info|log) are empty. Msmtp.log has no message for this mail. This is comprehensible because the Django log says it was not possible to connect to a smtp process. But I have no running smtp server. I only have msmtp as local mta client.

On command line sending an email via msmtp or sendmail works, also for the user lavaserver
