[Dovecot] IDLE command timeout

[Sim Harbert]

Is it possible to change the IDLE command timeout to be more than 30 
minutes?  I have a client on my PalmOne Treo 600 which will stay in IDLE 
mode as long as it can.  I would like to set the timeout to something 
much higher than 30 minutes.  Maybe several hours or even more.

I don't see a configuration setting for this value in 
"/etc/dovecot.conf".  Am I missing something?

Thanks,
