"some" tip could be to detail some 'defered messages'
"some" general tip should be to read the docs
"some" more global tip would be to read about posting questions ,-)
(like being more precise with fuzzy terms like mail gateway which
gives but a frail idea about your actual architecture)

I've a internal mail server running it sends all the outbound mails to
another internal server which used to relay mails through DNS to all
the outside domains, but in some domains we are not able to send mails
and getting defered messages like

And did you check the url above? Especially the link about how
give them details about your blockade?

There are different possible problems in your postings, at least those two:
- you post as example.com (is that your domain?, if not maybe some relay don't
passionately love spoofed senders)
- if your IP is really 11.45.87.11 one problem is it doesn't resolve
very well, and in any layer.

So, although at first I thought you had wrong questions now it seems you have wrong problems ;-)
