Don't make assumptions about which TLDs that are or are not allowed -
the domain part of an email address could be validated with this:
and .anythingyouwant now that the TLD space has been opened up....
@[a-z0-9][a-z0-9-]*(\.[a-z0-9][a-z0-9-]*)+
A test for total length and valid use of hyphens should be added.
See
RFC1034. Then look up the A record.
Or better, the MX record... :)
An MX record is not required to accept email for a domain. The
relevant RFC (can't recall the number right now) states that it
should fall back to using the A record if no MX record is present.
