I have raised a request with "The Planet" (the hosting provider, it does not 
provide a web interface) for the PTR record. I think I am slowly getting the 
point of this reverse DNS lookup. It adds for an extra layer of security to 
prevent spam because the spammers might not have access to the manipulation of 
PTR records. 

But I have another doubt, suppose that a particular ISP does not allow for 
changing the PTR records or assigns dynamic IPs (like BSNL), then would it not 
be possible for hosting an email server? Would services like Gmail blacklist 
such IPs completely?
