Email not working and no way of debugging

[Crocmagnon]

I'm trying to setup plausible to send weekly and monthly reports. I added the relevant variables but I don't receive the emails.

I couldn't find any way to send an email immediately, and I don't really want to wait 1 week between retries 😊

Here's my conf:

MAILER_EMAIL=plausible@mg.augendre.info
SMTP_HOST_ADDR=smtp.mailgun.org
SMTP_HOST_PORT=465
SMTP_USER_NAME=plausible@mg.augendre.info
SMTP_USER_PWD=supersecurepassword
SMTP_HOST_SSL_ENABLED=true
SMTP_RETRIES=2

I faced the same issue. You can run docker without --detach and when doing a password reset or registering a new user you get an error:

[warn] Failed to send Sentry event.Cannot send Sentry event because of invalid DSN

Which I think is weird. It happens with SMTP_HOST_ADDR set to localhost, 127.0.0.1 and the special host.docker.internal (see blow for requirement) and I guess is a bug.

Workaround that I used is letting the mail service relay it again

  mail:
    image: bytemark/smtp
    restart: always
    environment:
      RELAY_HOST: smtp.mailgun.org
      RELAY_PORT: 465
      RELAY_USERNAME: alice@example.com
      RELAY_PASSWORD: secretpassword

See: https://hub.docker.com/r/bytemark/smtp/

Add this to your service if you want to have the host addressable via host.docker.internal

    extra_hosts:
      - "host.docker.internal:host-gateway"

@Crocmagnon You can test/debug email delivery by trying to send a password reset to an existing account. You can check for any errors with docker logs <plausible-container-name>

To get weekly/monthly reports to work, you need to set CRON_ENABLED=1 in your configuration. I will cut a new release this month where this is enabled by default.

[Crocmagnon]

Thanks @kevinvalk. I'd like not to resort to another service since plausible should be able to speak to an existing relay.

@ukutaht, the CRON_ENABLED variable is not mentioned in the docs (here). I enabled it, will check if I get these reports 🙂

I can't find a way to send a password reset. The only page I found other than the site view is this one:

[metmarkosaric]

Does this work @Crocmagnon? https://plausible.io/docs/reset-password

[Crocmagnon]

Yes it does, thanks @metmarkosaric!
Using the URL provided in the docs on my self-hosted instance I've been able to try and send an email. My config was ok.

Thanks!

One issue still though, when I enable cron via the env variable, plausible is really not happy:

See the error log (happens at boot time)

[ukutaht]

Sorry my bad. It's CRON_ENABLED=true. And apologies for not having these things documented. Like I said, it will be enabled by default in future versions.

[Crocmagnon]

No problem! I just pointed it out to increase the quality of the docs 🙂

I can confirm that plausible boots fine with CRON_ENABLED=true! Thank you all for your help 👌
