This is the ability to send pages via e-mail. This is supported by most paging carriers and is a simple form of Internet Paging. Although SNPP or WCTP is the preferred method for Internet Paging do to the direct communications between your computer and the carriers gateway, it is not used as much and not many carriers support this protocol yet. Most of our products supports Windows Messaging and SMTP with the ability to use MX Record lookups. It is recommended that you try to use MX record lookup first by leaving the SMTP Server field empty.
