sending emails doesn't seem to work?

[imc67]

First: thanks for having Pretix in the Appstore!

I'm currently exploring the app and its capabilities and noticed that emails are not sent?

The configured email on app-level is an existing address and mailbox, this is the error on trying to send.

As far as I can see it tries to use the email smtp server at the domain of the app itself reserveer.REDACTED.xx instead of my.REDACTED.xx?

Hello @imc67

The mailing for the Pretix should be autoconfigured on every startup and is placed in the /run/pretix/pretix.cfg file.
Can you confirm that in that file it is correct?

Even if these values are correct it seems the mail is not sent.
I have reproduced this issue and I am now looking into it.

I think I see the problem here.
The task worker named celery is configured in /run/pretix/pretix.cfg to use redis as the backend and broker but somehow, celery still wants to use AMQP server (e.g. RabbitMQ) which does not exist and fails.

This might be a celery related issue similar to https://github.com/celery/celery/issues/6370

EDIT:
This was a wild goose chase and was some based on a log message I thought saw once.
But did not lead to anything.

@james Good to see you’re so committed to find the issue and solve it! Emailing is essential in this app otherwise people don’t get their tickets

Did you managed to find the issue?
