Question Accessing to mail (send & receive) only from one country

[malware]

Server operating system version

AlmaLinux 8.10 (Cerulean Leopard)

Plesk version and microupdate number

Hi all,

I would like to allow email access only for IP client in Italy.

I tried to add a firewall rule for
- Service: SMTP (submission port) server
- Service: SMTP (mail sending) server
- Service: POP3 (mail retrieval) server
- Service: IMAP (mail retrieval) server
to allow connections only from source IT and it works. But server will not receive email if the sender server is out of Italy.

Anyone could give me an idea?

Thank you in advance

I am not sure which ports you've exactly blocked. But port 25 needs to be unrestricted in order for your server to receive emails from other servers.
