Email Traffic Direction Rules

CA Gateway Security classifies SMTP rules according to the following email traffic directions. You can find the configuration menu for this function under Manager Console, Filtering, Content Manager Rules, SMTP. The rules for email traffic direction include the following:

• Inbound rules specify content filtering for inbound email traffic. These rules apply to email that originates outside your organization.
• Outbound rules specify content filtering for outbound email. These rules apply to email sent from your organization to addresses outside your organization.
• Internal checking rules apply to email sent to and from users within your organization. All email that originates from your configured subnets is processed as outgoing traffic even if the destination is internal.
