Mdaemon mail server issue

there are 50 mail servers with me they lie in the same data centre but in that 1 mdaemon mail server is creating a problem for me.

the mdaemon mail server is not able to send mails to other 49 mail servers (the mails do come but after lot of delay) but we are able to send mails from other mail servers to this mdaemon mail server.

there is only 1 domain on this mdaemon mail server but when they send mails to any other domains outside our data centre network the mails work perfectly fine.

Also it gives Winsock error 10060 in the logs sometimes.

By the look of it you are sending out using IP 203.201.252.36

If the recipient does a Reverse DNS check on that address before any commitment is made to accept your message there seems to be a big delay in that response.  See the following trace which was carried out using DNSStuff

Preparation:
The  reverse DNS entry for an IP is found by reversing the IP, adding it to "in-addr.arpa", and looking up the PTR record.
So, the reverse DNS entry for 203.201.252.36 is found by looking up the PTR record for
 36.252.201.203.in-addr.arpa.
All DNS requests start by asking the root servers, and they let us know what to do next.
See How Reverse DNS Lookups Work for more information.

How I am searching:
Asking g.root-servers.net for 36.252.201.203.in-addr.arpa PTR record:  
       g.root-servers.net says to go to ns3.apnic.net. (zone: 203.in-addr.arpa.)
Asking ns3.apnic.net. for 36.252.201.203.in-addr.arpa PTR record:  
       ns3.apnic.net [202.12.28.131] says to go to hyddns.tatanova.com. (zone: 252.201.203.in-addr.arpa.)
Asking hyddns.tatanova.com. for 36.252.201.203.in-addr.arpa PTR record:  Timed out [at 203.124.250.70].  Trying again.
Asking mumdns.tatanova.com. for 36.252.201.203.in-addr.arpa PTR record:  Reports mail.tataamc.com. [from 203.124.230.21]

Answer:
203.201.252.36 PTR record: mail.tataamc.com. [TTL 99999s] [A=203.201.252.36]
