Email Address Validity and Mail Host Check (Second Route)

omnial/email-validity-and-mail-host-check

Checks one email address and returns an overall valid flag, whether the address is well formed, its domain, whether that domain publishes mail (MX) records and the mail server host names, and whether the address is on a disposable-mailbox domain, is a role mailbox (such as info@) or is on a consumer webmail provider. Runs on a newer version of the checking service than Omnial's other mail-server email check, so each can back up the other.
