On Dovecot imap server 2.2.8 and newer, X-GUID should be used by SOGo
2.2.11 and newer. ANNOTATE is the old outdated standard still used by
Cyrus imap server.
See this resolved bug from Dec 2014: http://sogo.nu/bugs/view.php?id=3018

I have a small server setup which is working very well with the
exception of EAS on android devices (I haven't tried iOS devices).
The setup is as follows:
- Centos 7
- dovecot 2.2.10
- samba authentication using Sernet samba 4.2
- apache 2.4.6
- SOGo 3.0.1 (previously on 2.3.x with the same symptoms).
Thunderbird clients work fine
The web front end works fine (version 2 and now version 3).
When I first sync an android phone with the server using ActiveSync,
it flashes up "Syncing x/5500" emails. It then syncs about 10-15 and
no more. Contacts and calendars sync fine.
Subsequently the phone will collect e-mail automatically as it arrives
providing it hasn't already been read using Thunderbird. If an e-mail
/has/ already been read using Thunderbird it doesn't sync to the phone
at all.
Looking through the installation guide (p5), I note that the IMAP
server needs the ACL, UIDPLUS, QRESYNC, ANNOTATE (or X-GUID)
extensions. I have the first three but I can't find any reference to
the ANNOTATE or X-GUID extensions in the dovecot documentation. Could
this be the problem?
Any help would be much appreciated!
Thanks
John
