Can't retrieve mail via SMTP and gmail

Hi :slight_smile:

I’m trying to add my mailaddress to gmail (or another mail-client).
Pop3 works fine.

Sadly I can’t get SMTP working. I get this error message:
Authentication failed. Please check your username/password.
Server returned error: “Unspecified Error (SENT_SECOND_EHLO): Smtp server does not advertise AUTH capability, code: 0”

Did I configure something wrong?
How can I debug this?

Thanks :slight_smile:

Now I have these errors in my log:
