My first impression is that it would be better to do this in your MTA  
than mailman.  If nobody outside your domain can subscribe or post,  
you could just make Mailman invisible to them.

I don't believe you can do this without changing the code.  While you  
might use a negative lookahead assertion in a regular expression in  
Subscription rules ban_list, the unwanted subscriptions are rejected  
with a notice rather than being quietly discarded.

The Sender filters hold_these_nonmemembers and  
discard_these_nonmembers settings are checked in order, so I believe  
you could use ^[^@]+@(.+\.)?iitb\.ac\.in and ^.* respectively for those.
