This was tested on two machines

The problem I found is that when executing the command:

Email::Valid->address($address)

returns true when $address =
 'whatever@whatever.com{' or
 'whatever@whatever.com}' or
 'whatever@whatever.com*' or
 'whatever@whatever.com$' or
 'whatever@whatever.com#'

That is all that I tested, but I don't think that those addresses should
return true.
