Hey guys!

I tried to write a small synchronization tool to synchronize two different mail server via IMAP. Shortly I saw that both of my servers support the IDLE command. So I thought to use this command to implement a solution.

But I saw, that the IDLE command can be submitted only on a per-folder basis. Suppose I have n folders on my server, I will have n different threads. That has a very low performance.

Are there any other possible solutions? Did I misunderstand something when using IDLE?
