there is no smtp log.
It says authentication failed, are you sure about the password? ;)
yes, i am sure password is correct
I use Mailcow as well. It works (Except for some Nextcloud mail issues i have). Could it be because you have to use app passwords with the recent changes in authentication in Mailcow? Depending on your version and setup.

That sounds like a reasonable explanation. Is that the case @peterGopher?
