Insertion

MetaDefender Email Gateway Security enhances existing email security gateways adding proactive and preventive measures to them. To be able to do so, Email Gateway Security must be inserted into the email flow, typically between the email gateway and the mail server.

Depending on the direction of the email flow (for details see Configuration/Policy), the following needs to be set:

1. Inbound emails

   1. The email gateway must forward emails to Email Gateway Security
   2. Email Gateway Security must forward emails to the mail server

2. Outbound emails

   1. The mail server must forward emails to Email Gateway Security
   2. Email Gateway Security must forward emails to the email gateway
