Hi,

I want to set this on the Host Access Control.

IMAP - OUR IP,GOOGLE IP - ALLOW
IMAP - ALL - DENY

POP3- OUR IP,GOOGLE IP - ALLOW
POP3 - ALL - DENY

SMTP - OUR IP - ALLOW
SMTP - ALL - DENY

Would we still be receive emails from outside?

Hello @vponteras,

Dovecot (IMAP/POP) and Exim (SMTP) don't support TCP wrappers and thus are not supported as services you can restrict access to through WHM >> Host Access Control. I recommend using a firewall management utility such as CSF if you want to restrict access to these services.

Note that internal case CPANEL-17242 is open to ensure the services that don't support TCP wrappers are not included in WHM >> Host Access Control.

Thank you.
