Which kind of evidences do you need ?

What about logs? sogod.log.

A pcap on port 20000 when that happens would be good to.

Ok I will do it ASAP

We need a pcap.

Could you kindly tell me the syntax of the pcap filter/command to sniff the traffic ?

tcpdump -i lo -s 0 -w /tmp/dump.data tcp and port 20000

Uploaded pcap

Tested with both android 4.4.3 and iphone ios 7.x
I was able to sync on android just one time.

Any news about this issue ?

Hi,

Having enabled IMAP debug in sogo.conf I get the following in sogo.log. I feel the issue might be that the "null" folder name being presented to IMAP. Not sure if the missing setannotation support in my dovecot could be causing the issue ...

What IMAP server are you using?

As you can see SETANNOTATION isn't supported nor X-GUI. One of the two is required for proper ActiveSync support.

dovecot-2.2.12 built from sources ...

X-GUID seems to be supported? Anyway how to get setannotation support into dovecot?

sorry for the dovecot question. Am installing dovecot-metadata-plugin will report after testing ...

Well indeed it seems to be supported. Have you compiled SOGo yourself?

yes. SOGo/SOPE 2.2.5 downloaded from sogo.nu

You might to run sogod inside GDB and set a breakpoint on "seletct" (in NGImap4Client) and produce a stacktrace when you get a "nil" value.

See http://www.sogo.nu/fr/nc/support/faq/article/how-do-i-debug-sogo.html

ran using gdb. hit "virtual memory exhausted: ...".

set ulimit to allow more memory resources and the issue seems to be solved. running with or without GDB does not give the "null" folder as before ...

thanks for point me in the right direction ...

regards,
Anantha Potty
