NC sends no mails but doesnt indicate any errors

Nextcloud version : 15.0.5
Operating system and version (eg, Ubuntu 17.04): unknown (Webhosting)
Apache or nginx version (eg, Apache 2.4.25): Apache
PHP version (eg, 7.1): 7.2

The issue you are facing:
Nextcloud ist sending no Email, but doesn’t indicate any errors in the logs. The mailserver generally works and generally works with nextcloud (second testcloud has no issues)
Because no errors are prompted Im not sure how long the issue exists.
apart from not sending any mails the cloud works fine and doesnt produce any errors in the logs.
the mail configuration in config.php is the same as in the working testcloud.

I couldnt find a similar issue but maybe somedody has an idea to fix this.


Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. Every way to get Nextcloud to send a mail, eg testing, forgotten pw etc.

The output of your Nextcloud log in Admin > Logging:

no error messages generated

You should search the forum again for existing issue, because email problems have definitely been discussed in details only a couple of days ago.

I searched an found no existing problem that explained mine.

I still tried the proposed solution but they did not work.

In the end I “fixed” it without knowing how by checking all settings and changing a few unrelated to the mail settings but afterwards it worked.

As there were no errors, warnings before or after I still dont know what caused it.
