E-mails are no longer sent

Help
1

Hello there,

I have configured Postfix as a relay host, so my e-mails are not sent directly from my server but from an e-mail server at OVH.

For several weeks now the e-mails are not being sent anymore. The problem is not related to the configuration of Postfix because before it worked, and I manage to send e-mails with other software installed on my server.

I checked the e-mail settings on the administrator dashboard, tried to send an e-mail and I got the message SMTP Test e-mail sent correctly.

I enabled the SMTP debugging settings, set LOG_LEVEL to trace, and this is what it gives me when sending an e-mail:

2020-12-10 00:09:29.109] [response] [INFO] POST /admin/test/smtp (test_smtp) => 200 OK

In the end, I don’t receive my e-mails…

What other tests can I do?

In advance, thank you!

Hello,

If you have enabled the smtp debug setting the above can not be all from the output in the log file. So either the setting wasn’t saved or something else is wrong

3

What am I supposed to understand?

If you have enabled SMTP_DEBUG=true, then you should have gotten a bit more then only

2020-12-10 00:09:29.109] [response] [INFO] POST /admin/test/smtp (test_smtp) => 200 OK

There should be a lot of lines above that regarding the SMTP.
So… either that setting wasn’t saved, or something else is wrong.

Checking the SMTP debugging option on the administration interface doesn’t work, I had to manually add SMTP_DEBUG = true so the Bitwarden RS configuration file.

And now actually I see more information…
