What do the logs tell you with SMTP_DEBUG=true?
It could be other settings.

Can you also check with docker exec vaultwarden-app printenv | grep SMTP_PASSWORD if the password is actually set correctly?

It might depend on the SMTP server? Curious that it works with Thunderbird. Does it use LOGIN or a different authentication method?

@Tragen For some strange reason I can't reproduce this. I use the exact same password as you entered here, it produces the exact same base64 encoded string. And it works on my Postfix instance without any issues using both Login and Plain as Authentication Method.

Very strange then.
I will close this ticket.
At least somebody can get a hint with this ticket if he hits the same problem.

Strange, the password does contain the right character. Maybe it needs a different encoding. Not sure if that is on our side, or we need to let the people from lettre known.

Maybe @paolobarbolini has a good idea?

Try to set SMTP_AUTH_MECHANISM to Login or Plain and see what happens.
