SMTP Connector

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