It took forever to come up to the banner for me when telnetting to it on
port 25.

reports that you do not have a reverse DNS entry (PTR record) set up. This
is bad news for a mail server. It also reports your 202.163.96.4 DNS server
is not responding.
FWIW,

Subject: [FW-1] Delay response of Check Point Firewall-1 Gateway for SMTP
connections.
Date: Wed, 25 May 2005 11:30:53 +0500
Dear ALL,
We are using Check Point firewall gateway alongwith its VPN module, there
are about more than 600 mail users.
I used to receive all internet bound emails on firewall (which acts as
smart host) and later firewall sends it to my mail server which is resided
inside the internal lan (over private IP). Now a days we are having a
problem with my check point firewall server SMTP services, there is a delay
of about 30-35 sec before establishing a connection on port 25.
MX record entry for "pop3khi,engro.com" mail server is mapped on firewall's
real IP address (i.e. 202.163.105.245), for last few days my firewall does
not respond well over internet on port 25, it is taking longer time to
respond against SMTP connection than normal and as a result internet bound
incoming mails queued up either on our back up server placed in a local ISP
or bounced back to the sender.
Would appreciate if any of you could please advise some solution to get
this issue resolved.
Thanks in advance for your support,
Regards,
