SQL Server 2012

SQL Server 2012

Configuring database mail in order to get alerts and notifications from my SQL Server 2012, I am not able to send test emails.
Tried smtp.soho.com port 587
Tried smtp.soho.com port 465 ssl
Using my user@domain.com as user name and the proper password as authentication.

Sending to the same email address that is used as authentication!

Relevant link is https://help.zoho.com/portal/en/community/topic/sql-server-2008-databasemail-not-connecting-to-smtp-zoho-com-exception-message-cannot-send-mails-to-mail-server-the-operation-has-timed-out

Using anonymous relay for google server is working, (but only gmail accounts can be notified) so, it is needed that zoho could accept MS SQL Server emails.

Log error at following.
