Hello Jitendra,
Let me clear my self by saying that when I am able to
telnet to desired ports(here 25 and 110) it means that those ports are open on
my local firewall and ISP firewall. And if I am not able to telnet the same it
means either my local firewall is having problem or my ISP firewall is having
problem.
I will request you to check your company firewall,
your local pc firewall and ISP provider fire wall.
1. I don't think its dns entry issue.
2. Please try to telnet these ports from mail server and from dns also.
Thanks and Regards
Vikrant Telkar

Hi ,
I dont know the the exact cause but i think this may
be due to blocking of telnet session
also 110 is for POP so it is generally for downloading
mails from mail server to mail client
SMTP 25 port is for sending mails from one mail server
to another
so this is likely that your mail server port 25 & 110
is open for internet but telnet to 25 may be blocking
by som ISP this is possible using IPS signature
blocking.
