[SOLVED] Trying to disable QRESYNC for imap capabilities

[Scummer]

After hours of digging why my Nokia N900 modest client doesn't want to show my messages anymore, I find this:

H00004 SELECT INBOX (QRESYNC (1 24715))
H00004 BAD parse error: wrong character; expected ' ' but got '('

That's just awesome, so 6.0.9 is broken for IMAP QRESYNC support.

So my thought is to turn off QRESYNC.. Easy, right?

I have disabled QRESYNC capabilities through zmprov with the mcf command.

Taking a look at /opt/zimbra/conf/nginx/includes/nginx.conf.mail it shows that in fact the conf is updated:

    imap_capabilities         "ACL" "BINARY" "CATENATE" "CHILDREN" "CONDSTORE" "ENABLE" "ESEARCH" "ESORT" "I18NLEVEL=1" "ID" "IDLE" "IMAP4rev1" "LIST-EXTENDED" "LITERAL+" "MULTIAPPEND" "NAMESPACE" "QUOTA" "RIGHTS=ektx" "SASL-IR" "SEARCHRES" "SORT" "THREAD=ORDEREDSUBJECT" "UIDPLUS" "UNSELECT" "WITHIN";

So far so good.

However, my N900 modest client still doesn't want to refresh

So I start digging:

root@mail:/opt/zimbra/conf# tcpdump -A -n -s 1500 -i lo port 7143

And find this:

E..dx.@.@...
...
..........@.........b.....
........H00001 OK [CAPABILITY IMAP4rev1 ACL BINARY CATENATE CHILDREN CONDSTORE ENABLE ESEARCH ESORT I18NLEVEL=1 ID IDLE LIST-EXTENDED LIST-STATUS LITERAL+ LOGIN-REFERRALS MULTIAPPEND NAMESPACE QRESYNC QUOTA RIGHTS=ektx SASL-IR SEARCHRES SORT THREAD=ORDEREDSUBJECT UIDPLUS UNSELECT WITHIN XLIST] LOGIN completed

What the heck??? I turned off QRESYNC and it still announces the QRESYNC as a capability? What is going on?

I still can't believe what's happening, so here comes another test:

root@mail:/opt/zimbra/conf# openssl s_client -host localhost -port 993

Low and behold, the announcement is this after I login:

C OK [CAPABILITY IMAP4rev1 ACL BINARY CATENATE CHILDREN CONDSTORE ENABLE ESEARCH ESORT I18NLEVEL=1 ID IDLE LIST-EXTENDED LIST-STATUS LITERAL+ LOGIN-REFERRALS MULTIAPPEND NAMESPACE QRESYNC QUOTA RIGHTS=ektx SASL-IR SEARCHRES SORT THREAD=ORDEREDSUBJECT UIDPLUS UNSELECT WITHIN XLIST] LOGIN completed

Right now I just don't know what to do, I'm assuming nginx just passes through the IMAP connection and the zimbra imap server announces the capabilities which I have not found a solution anywhere to turn off QRESYNC so at least I can use my N900.

Extremely frustrating this is and I'm wondering if someone knows how to either:
1. Change the sourcecode for the zimbra imap server so QRESYNC works properly
2. Disable QRESYNC as an imap capability

Thanks

Found it in bugzilla
Bug 52403 – QRESYNC support broken

Dang.. I guess I have to wait for the fix.

Fixed it. Now 6.0.9 works properly with QRESYNC.

Created an exact same linux install in a VM as my mail server.

Followed those instructions to download the 6.0.9 GNR source:
GNR on Debian Lenny - Zimbra :: Wiki

Edited line 746 in /home/public/p4/GNR-609/ZimbraServer/src/java/com/zimbra/cs/imap/ImapHandler.java
Deleting 'req.skipSpace();' so only 'req.skipChar('(');' is left.

Started the build with /home/public/p4/GNR-609/ZimbraBuild/buildZCS.sh and waited for it to finish.

Copied the resulting zimbrastore.jar from /home/public/p4/GNR-609/ZimbraServer/build to my mailserver, shutdown zimbra with zmcontrol stop and replaced zimbrastore.jar in /opt/zimbra/lib/jars/ and /opt/zimbra/jetty-6.1.22.z6/webapps/service/WEB-INF/lib and /opt/zimbra/jetty-6.1.22.z6/webapps/zimbra/WEB-INF/lib and /opt/zimbra/jetty-6.1.22.z6/webapps/zimbraAdmin/WEB-INF/lib

Fired up zimbra with zmcontrol start

Fired up the N900 mailclient and voila it refreshes and works as it should. Perfect!!
