[fetchmail-users] only one message gets fetched using IMAP idle

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Hello!

Using fetchmail successfully with polling by interval for several months I 
just tried to use the IMAP idle-extension to get my mails delivered immediately.

Unfortunately only one message gets fetched - after that, fetchmail recognizes 
the arrival of a new one, but instead of downloading the message, it just 
triggers another idle.

Who's to blame? My config, a stupid server or a bug in fetchmail?
