A simple implementation finds out what the highest unique id is in the folder and then asks for all of the envelopes for messages from UID 1 through the high UID. Relying on a correlation between UIDs and recent messages allows a client to start with higher UIDs and (usually) end up fetching the envelopes of the most recent messages first. Incremental synchronization after this initial synchronization is made much easier because | A simple implementation finds out what the highest unique id is in the folder and then asks for all of the envelopes for messages from UID 1 through the high UID.
