Thanks for the responses Guys! i tried it. But it still doesn't work.

It shows an error in my Cisco ASA log;

"Portmap creation failed for tcp src inside 192.168.135.14/4978 dst inside 195.x.x.x/443"

where 195.x.x.x is my outside interface and 192.168.135.14 is one of our hosts where i trie to open our mail.xx.xxx address.

Strange!!. I have done a very similar scenario here and it worked!!.

What are the commands you used? Could you post the exact syntax and any other changes made to the config (if any).
