Originally created by @zero-thermo on GitHub (Sep 21, 2022).
Original GitHub issue: https://github.com/go-vikunja/vikunja/issues/48

Frontend v0.19.1 + API v0.19.2 setup via docker-compose.

Emails are successfully sent and received, but with the following error in the API logs (and via ./vikunja testmail):

ERROR	▶ mail/func1 1bd Error closing the mail server connection: not connected to SMTP server

Bug or WAI?

Used the following variables to enable email in docker-compose.yaml:

      VIKUNJA_SERVICE_ENABLEEMAILREMINDERS: 1
      VIKUNJA_MAILER_ENABLED: 1
      VIKUNJA_MAILER_FORCESSL: 1
      VIKUNJA_MAILER_HOST: <my smtp server>
      VIKUNJA_MAILER_PORT: 587
      VIKUNJA_MAILER_USERNAME: <my username>
      VIKUNJA_MAILER_PASSWORD: <my password>
      VIKUNJA_MAILER_FROMEMAIL: <my email>

Might be a bug in Vikunja. Do you have any additional logs prior to the error?

Yes that's right -- emails are successfully sent and received in both cases despite the errors

For me at least the testmail sends successfully without an error.

go run ./... testmail testmail.vikunja@lucab.de

[...]
2022/09/24 19:53:03 Using config file: /dev/private/vikunja/api/config.yml
2022-09-24T19:53:03.495292+02:00: INFO  ▶ cmd/func10 001 Sending testmail...
2022-09-24T19:53:07.516869+02:00: INFO  ▶ cmd/func10 002 Testmail successfully sent.

Though I do get a similar error for the same config:

2022-09-24T19:57:11.592828+02:00: ERROR ▶ mail/func1 1ca Error closing the mail server connection: not connected to SMTP server

I also saw that for the created mail connection there is a default timeout of 15 seconds (mail.NewClient):

// DefaultTimeout is the default connection timeout
	DefaultTimeout = time.Second * 15

Passed timeout parameter to mail server. Now it works:

2022-09-24T20:13:37.324797+02:00: INFO  ▶ mail/func1 0cf Closed connection to mail server

Will open PR...
