I am very new to regex and need help.
I am looking for a regex which matches only if any of 3 email ids are found in the message headers (lets say a@gmail.com, b@gmail.com and c@rediffmail.com) if there is any email id in sender header then it shouldn't match.
Is it possible to create this kind of regex? if yes, please advise.
