MailMarshal applies Connection Policy while the MailMarshal Receiver is receiving a message from a remote email server. Connection Policy can cause MailMarshal to refuse to accept a message based on the size or origin of the message. Because Connection Policy is based on the limited information available while the message is being received, only a few conditions are available in Connection Policy rules.
MailMarshal applies Content Analysis Policy after a message has been fully received. They are processed by the MailMarshal Engine. Content Analysis Policy can evaluate a large number of conditions, because the complete email message is available for evaluation. Content Analysis Policy can also take a large number of quarantine and logging actions.
MailMarshal applies Dead Letter Policy when a message cannot be unpacked, or cannot be processed, due to errors in message formatting. By default these messages are quarantined in special folders. You can specify a limited number of actions to deliver some of these messages to their original destination or an alternate address.
