cannot send invitations when SMTP is configured without authentication

[pescobar]

my smtp doesn't require authentication so I only configured SMTP Host and SMTP Port and I left username and password empty. When doing this I can send emails using the send a test email button but when I try to send invitation in admin >> users I get his error message:

In order to send invitation e-mails, you must first configure SMTP settings

If I try to add a fake smtp user and password the webui allows me to send invitations but I get this error in the logs:

Exception while invoking method 'sendInvitationEmail' AuthError: Invalid login - 503 5.5.1 Error: authentication not enabled

I found this error in latest docker image, I think version 0.9

I get this error. ....

I have SMTP Connecting to an SMTP Relay Server. I pass my username and password.
I think this is related to SMTP Auth which I need to specify plain....
