This is the standard IDLE.  Try telnetting in again and before the 
logout doing:

a02 SELECT INBOX
a03 IDLE

You should get back a response of:

+ entering idle mode

If you had FAM/Gamin installed (and recompiled against them) you would 
instead see something like:

+ entering ENHANCED idle mode

Thunderbird needs to be told to use IDLE commands (Account Settings, 
Server Settings, Advanced, "Use IDLE command if server supports it).

In the standard idle mode which your using, the imapd server will "poll" 
your selected Maildir every now and then and update the client if there 
have been any changes (new mail, deleted mail, changed read status, etc).

In the enhanced idle mode, which you need FAM or Gamin installed and 
compiled against to use.  The FAM/Gamin process will hook in to the 
Linux kernel which will tell it when there is a change to your Maildir 
and let you know immediately.

Enhanced IDLE is both faster (since you get the notifications 
instantaneously) and more efficient for your server (since the client 
isn't asking it 5,000 times if there's any changes).

The comparison I like to make is your typically family vacation trip.  
It's very inefficient (and annoying) for the kids to sit in the back 
seat asking "Are we there yet, are we there yet, are we there yet?".  
It's much more efficient for Dad to offer regular status updates, "The 
sign says we're 60 miles away...The sign says we're 13 miles away..."

I would recommend Gamin over FAM as it's maintained where SGI has let 
FAM die a quiet death, it also depends on much less in terms of services.
