<font face="Times New Roman, Times, serif">Hi All , <br>
<br>
I am getting problem of slow blackberry syncing with nginx and
cyrus-imapd setup. <br>
<br>
Below is the setup details. :--<br>
----------------------------------------<br>
<br>
We have setup the servers with ngnix ( nginx-0.6.39-5.el5 ) and
cyrus-imapd (cyrus-imapd-2.3.7-7.el5 )<br>
Nginx working for pop3, pop3s, imap and imaps3 with internal
cyrus-imapd server where actual mailbox are present.<br>
<br>
The 1st request coming on nginx and then it get proxy to
cyrus-imapd server.<br>
For the users who are using the Blackberry ( BIS ) , for them
email are syncing slowly say after 2-4-5-10 min.<br>
<br>
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. <br>
<br>
I checked thunderbird email client with "idled" , the emails are
syncing instantly i.e without delay.<br>
<br>
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 ) <br>
<br>
My queries :--<br>
---------------<br>
<br>
1) Will blackberry work fine with Ngnix and proxy server to
cyrus-imapd <br>
2) Do any one have live working setup like above , how you are
managing ? <br>
3) How the Blackberry ( BIS ) is working in that case.<br>
4) Is there any extra setting require in cyrus-imapd for
Blackberry ? <br>
<br>
I am looking the solution in nginx forum also. <br>
<br>
Kindly guide for above <br>
<br>
Regards<br>
