6 Understanding Email Policy, Policy Groups, and Rules
The MailMarshal Email Policy defines how MailMarshal treats each email message that it processes.
The Email Policy includes Connection Policy, Content Analysis Policy, and Dead Letter Policy. Each type of policy consists of one or more policy groups. Each policy group contains one or more rules. Each rule has three parts: User Matching, Conditions, and Actions.
MailMarshal applies Connection Policy while receiving a message. It applies Content Analysis Policy to each message after it is fully received. MailMarshal uses Dead Letter Policy to handle messages that cannot be unpacked or processed due to errors in formatting.
When applying policy, MailMarshal checks the User Matching criteria for each policy group. If a message meets the User Matching criteria for a group, MailMarshal evaluates the message according to the User Matching and Conditions sections of each rule in the group. When a message meets the criteria of a rule, MailMarshal applies the specified actions to the message.
