I used gmail alias for my email hosting but today it got this error: TLS Negotiation failed, the certificate doesn't match the host., code: 0
Does anyone have same problem?
I tried to search and found there are more people are facing same problem https://support.google.com/mail/thread/38789651?hl=en but seem no solution to fix it. It could be from Google gmail.
Mail still could receive but send out is not possible.

If you are you're using Cpanel on the server and have root access of WHM panel. So, please follow the step to fix this issue.

Login from whm -----> Exim Configuration manager-------->Security --------------------------->

Require clients to connect with SSL or issue the STARTTLS command before they are allowed to authenticate with the server. --->Off

And save it.
