Title: SASL LOGIN authentication failed: Invalid authentication mechanism
Post by: juanmi@arco2000.es on April 22, 2020, 11:29:03 am

Hello everyone. I'm glad to be here. I have installed Zentyal 6.1.2 and everything works great for me except a few things: SSMTP over port 465 and some valid Hotmail authentication method. I tell you what I'm doing to see if you can help me out.

I have installed everything, to enable SMPT on port 587 I have installed a letsencrypt certificate with the host name of my server, I have used it for all services according to this page (https://doc.zentyal.org/es/ca.html#configuracion-de-let-s-encrypt)

I want to configure the account to send my emails from other platforms (Gmail, Thunderbird, Hotmail). I have made it work in Thunderbird (Plain Password) and Gmail, but it does not allow me to use it in hotmail, this page (https://support.office.com/en-us/article/outlook-com-no-longer-supports-auth-plain-authentication-07f7d5e9-1697-465f-84d2-4513d4ff0145) say me Auth Plain is not longer supported by hotmail.com. If I configure hotmail gives me the error that gives title to that message:

SASL LOGIN authentication failed: Invalid authentication mechanism

Nothing works on port 465, neither Thunderbird, Hotmail, or Gmail.

How can I enable Kerberos GSSapi Auth?
How can I enable the auh in the port 465 with SSL?
Can you give me any hints?

Sorry for my English ;-)

Thank you in advance.

Since my first ticket for Let's Encrypt support: https://github.com/zentyal/zentyal/issues/1836 (it has been closed by Zentyal Team).

I have created a second ticket for Let's Encrypt support which has been closed by Zentyal Team too.

I have created a third ticket for Let's Encrypt support, can you like, comment on it?
