SEMS Mail Policy

Hi Guys,

Based on mail-policy-poster.pdf downloadable from https://YourSEMS.YourDomain.com:9000/omc/help/Extr...
 

The environment is a SEMS with some PGP Desktop Email to encrypt source and users encrypted at the gateway.

Please someone help me understand how in the mail flow, policies can identify each of the conditions.

Examples:

- "Service type is SMTP / POP / IMAP Inbound / Outbound" - It is clear that the protocol identifies the protocol but where and how it determines the direction ..?

- "Service type is Microsoft Oulook (MAPI) / Lotus Notes" - How to identify if Lotus or Microsoft ..?

- "Service type is PGP Universal Web Messenger" - Where in the message identifies this; if the message is sent from a Notes email client / Outlook ..?

- "Aplication is internal / external PGP Desktop" - There is an ID that is add the email you understand what "true" ..?

Thanks.
