Last weekend I upgraded my server (complete reinstall, actually), from Debian sarge to wheezy, which brought me from dovecot 1.x (I think) to 2.1.7. It's all working now, *except* that the MUA I use on Android, Kaiten (a fork of K-9), apparently no longer gets IDLE notifications.
Before the upgrade, when mail arrived, Kaiten would pop up an Android notification immediately; now, it never does (or it might, hours later, with all the messages it notices at that time--presumably this happens when its background service gets killed off and restarted).

The weird thing is that IDLE still works flawlessly with Thunderbird, which suggests this is a protocol interaction between Dovecot 2 and Kaiten. (I plan to check with the Kaiten folks next.) Has anybody here seen this? Is there something I can turn on in Dovecot to help debug it?

I did check my old Dovecot settings, and they didn't specify anything non-default about IDLE.

Thanks in advance!

My configuration from dovecot -n: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.9.3-x86-linode52 i686 Debian 7.0 log_timestamp = "%Y-%m-%d %H:%M:%S " mail_access_groups = mail mail_location = mbox:~/mail:INBOX=/var/mail/%u mail_privileged_group = mail passdb { driver = pam } protocols = imap pop3 service auth { user = root } service imap-login { inet_listener imap { port = 0 } } service pop3-login { inet_listener pop3 { port = 0 } } ssl_cert =

and the no-comments version of conf.d/20-imap.conf:

protocol imap { imap_idle_notify_interval = 10 mins }
