The discussion makes it clear why it is not possible to make a distinct 
edit.  Some tuning would have to happen and it would not always work, 
but like a date edit you could design one for the standard and one for 
the 2 dot emails and test the email against both, if it passes either it 
  is a good email address.

I think the solution is some edits for the various formats and then some 
processing to see if it complies with any edit.

Your scope of customers might determine if one would work or you need 
more depth for global email options.
