Perhaps your company may want to look at other firewalls that can do domain-based filtering.

That is right. We can have ip based filtering on ASA.

Hi Prashant,
There are 2 ways out of this:
1. you stick to one of the ip addresses of imap.gmail.com and use the ip address instead of the name. Ask your network admin to allow access to that ip address.
2. You yourself use a static ip, (or get a static ip) from the network admin. Then ask him to add an access-list entry like:
access-list acl_name permit tcp host
That way you can now access all internet ip's on port 993. These would include all imap.gmail.com ip addresses as well.
Lemme know if it helps.
