Hi All ,
I am getting problem of slow blackberry syncing with nginx and
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
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
