Mail Domain Change

Hi,

Currently we are using tvsmotor.co.in as our mail domain..i.e name@tvsmotor.co.in

but we have bought one more new domain tvsmotor.com, the same has been added as approved domains in exchange.

But when we send mails from outside, it is not delivering, whether we need to do any changes in gateway to accept mails to this new domain

please do the needful

Regards,

S.Srikanth
