SMTP Connector

The SMTP Connector allows you to transfer SMTP data unilaterally across NetWall. There is a built in SMTP server in Netwall BLUE that will receive mail from SMTP clients in the BLUE network. SMTP traffic will be transferred from NetWall BLUE to NetWall RED, where we will configure a built in SMTP client that will send the traffic to a SMTP server in RED network.
