==Communication between Systems==

There's no stand-alone FTL communication between systems.  Messages have to be carried by ship.  

In most Mandate systems, there is a system-wide comm network that holds a database with every message.  When mailships enter the system, their copy of the database is compared to the one existing in the system.  New messages are uploaded and messages known to be delivered are deleted.  The mailship's copy of the database is similarly updated.

When end users enter any system, they can check the local copy of the database, download new mail meant for them, and upload new messages for delivery.

Mailships run every day, and a message can be delivered from one end of the sector to the other, as well as every system in between, in less than a week.
