Email datatype does not accept data like zzz@yyy.ac.in

Email datatype does not accept data like zzz@yyy.ac.in

i was trying to create an application where EmailIDs are to be stored and processed. It was working fine UNTIL someone wanted to enter an id that goes something like studentNNN@IndiaUniv.ac.in [ obviously, both studentNNN and IndiaUniv are fictitious, but the ac.in IS a valid suffix !!]

this was not acceptable and i had to change the field to type single text line which works but is not a very happy solution.

would appreciate a fix
