Hi Everyone,

I have configured MTA on Check Point with TLS inspection.Mail flow is like this

Logix----> Load Balancer----> Checkpoint.

Logix is hosting the mails on cloud which is pointing on Load Balancer public IP which is NATed to Check Point Gateway external IP.

Mails are not delivering to End users,Mail queue on Check Point is empty.

No errors in /var/log/maillog

Able to see continuous traffic on port 587 towards Check Point and reply from Check Point as well.

We are not able to Telnet Check Point with Port 587.

When we enable MTA on Checkpoint with TLS inspection,on which port it will expect the mails.
