ngnix + cyrus idled + blackberry working slow.

[Zbierski Christophe]

Hello, do you have the opportunity to do a tcpdump ?, and is the idle works well with blackberry.
Otherwise, is it possible to disable the idle (in this case, is the noop function that should be used - slower that idle).

Hi All ,

I am getting problem of slow  blackberry syncing with nginx and cyrus-imapd setup.

Below is the setup details. :--
----------------------------------------

We have setup the servers with ngnix ( nginx-0.6.39-5.el5 ) and cyrus-imapd (cyrus-imapd-2.3.7-7.el5 )
Nginx working for pop3, pop3s, imap and imaps3 with internal cyrus-imapd server where actual mailbox are present.

The 1st request coming on nginx and then it get proxy  to cyrus-imapd server.
For the users who are using the Blackberry ( BIS ) , for them email are syncing slowly say after 2-4-5-10 min.

After analysis we found that when Blackberry make a connection to nginx server and then session is not maintain for long period for "idled" protocol  on both server.  Because of this emails are not syncing instantly on Blackberry.

I checked thunderbird email client with "idled" ,  the emails are syncing instantly i.e without delay.

If I use single cyrus-imapd server without ngnix then emails are syncing instantly on Blackberry ( i.e session also maintain continuously and instant sync )

My queries :--
---------------

1) Will blackberry work fine with Ngnix and proxy server to cyrus-imapd
2) Do any one have live working setup like above , how you are managing ?
3) How the Blackberry ( BIS ) is working in that case.
4) Is there any extra setting require in cyrus-imapd for Blackberry ?

I am looking the solution in nginx forum also.

Kindly guide for above

Regards
Jayesh Shinde
