Hello!
I have a problem with the exchange server because when I want to send an e-mail that has this combination ".@" it gives the following error: "one or more recipients are invalid" and that is NOT true. There is any possibility to solve the regular expresion that verify the format of an e-mail address?
Gmails users are allow to choose that combination for an e-mail address and is impossible send an e-mail throw an exchange server.
Thanks in advance.
