[Dovecot] meaning of parameter imap_idle_notify_interval??

[Ingo Thierack]

Hello,

once more again.

upgrade the server to the latest kernel and libs (namely CentOS 5.4).

Same problem.

Set notify interval to 180 seconds.
The message appears without intervention around 140 seconds after
it was delivered to the inbox.

2009-10-26 21:01:09 | dovecot:               |  deliver(ingoiwt at ghostdive.org): sieve: msgid=<ac2e3a8f0910261301r4d1f38dfx83e6d01d29394fd3 at mail.gmail.com>: stored mail into mailbox 'INBOX'

In thunderbird it appears around 21:03:30 

It looks like, only when dovecot sends the message, thunderbird will refresh its view.


At the moment, i set it to 10 Seconds. But this will be an overkill for
an mobilconnection :-P
