We have implement imap idle in web mail built by us to havepush mail feature. IMAP idle working perfectly with browser notification and we are happy with it but having one issue with users who close the browser directly and never logout in that case there are number of idle connection which are not in use and users are unable to login once IP wise connection limit is reached.
Dovecot is not closing connection which are not in use, is there any setting available which can help me to resolve this issue.
I had much the same situation where a user signed up with a roaming wireless carrier that assigned a new IP to the client whenever it got passed from one access point to another. Good fun when this person took a bus ride through the city, leaving orphaned connections in its wake.
The IDLE disconnection timeout is hardwired in the Dovecot code
http://wiki.dovecot.org/TimeoutsIt's set to the RFC minimum of 30min. You'll have to recompile Dovecot to lower this to a non-RFC compliant value. I'm not sure how this this will affect clients, but 30min seems to be overly generous.
