Anyone knows what would be an answer for this question. I can't figure the part after @

write input mask for

cctplan@key.itim.org

cctplan - Three up to 12 characters(no space). For letters, always lower case.

I know that the answer for this part would be

key.itim.org - A minimum of five characters (including '.') but no longer than 15 are required. Space characters are not acceptable.

i have already checked out msdn, there is nothing that i can use to Not include a space but include any characters.

Hey, are you trying to validate email address or what? If you are trying to validate email address, there is no full-proof validation technique for that. Only way to extract a working email address from user, is to ask user for an email address and send any login information (password, username) in that email address. This way users are forced to fill out the valid email address and they themselves will validate their email address.
