Question Load Balancing & emails

[sukyno]

Hello,
I am completely new to the Plesk interface and I would like to ask a few questions.

1. Is it possible to do something via nginx Load Balancing? I would need to install the same site on multiple VPSs that will work the same way.

2. I have a problem sending emails outside: / an email will come from outside, but it will not be sent outside.

Can you help me please?

1. No, not easily. Plesk doesn't have native LB support. It would take quite some work to get it work as load balanced.

2. Is the mail server running? Anything in the mail logs? Is outbound 25 allowed?

Hi,
2.I have port 25 enabled in both the firewall and the microtik. The administration still gives me the error "You cannot send emails from Plesk because outbound connections on TCP port 25 is blocked." but port 25 is really allowed everywhere.

Your provider probably blocks 25. Contact them

So is it possible docker proxy method, or similar like this, for example.com on plesk must be some method. please share with us. ideas welcome. many thanks
