Port 465 not opened for SMTP

I enabled Vesta Admin and Exim SSL by following and it's working.

Server Info:
Default Vestacp installed on Ubuntu 16 with Apache+Nginx+PHP7+EXIM etc.
SSL for port 465 - OK
rDNS for the mail server - OK
No IP blacklist
By Vestacp default Firewall-

Code: Select all

ACCEPT TCP/ SMTP 25,465,587,2525

I tried to connect SMTP on Joomla Global Configuration using SSL and port 465 but it's not working and when I checked I got message from another extension that, Port 465 isn't opened.

I can only connect SMTP with Port 25 with No encryption method (SSL/TLS).

For better mail delivery I need to use SMTPS port 465 with SSL encryption, but I don't know what's wrong with my server.

Your help appreciated.
