Outgoing emails from external domains do not work on port 465 (SSL) with MTA mode

We have Email Protection configured in MTA mode, an internal mail server using ports 993 (IMAP), 995 (POP), 465 (SMTP), everything works perfectly. The problem is when someone with an external domain arrives, they cannot send emails when they have port 465 configured in their account, only through port 587.

In the MTA firewall rule the services SMTP (S) (25,587) and SMTP (SSL) (465) are added.

I don't know if someone could help me?

Hi.

the basic configuration does not support 465, there is a change using the CLI to add 465 and I can't remember the commands.

Hi Ian

But why my local users can send mail trough 465 port (SSL) with no problem?

because you have a firewall rule allowing 465.
