Understanding Email Gateway Definition For Beefing Up Organizational Security

A simple email gateway definition for the layman would be that it is a machine that acts as a connection between multiple networks. It helps in the execution of the communication protocols along with active constraints that use a similar protocol between several systems. Thus for connecting two networks, the most straightforward mail gateway is used with the same kind of protocol or the mailer constraints. Therefore, the messages passing through the email gateway are encrypted, especially the outgoing mails, and the incoming emails, decrypted.
