[horde] ActiveSync: E-Mails show up several times on Android

[Michael J Rubinsky]

Quoting ich at sebmeyer.de:

> Hi,
>
> I am running Horde5 with Horde_ActiveSync-2.0.0beta4 on a fresh  
> horde install (both pear packages and database).
> The client is a Galaxy S2/Android with a CyanogenMod10 Nightly Build  
> (at most a week old), reported as "Android/4.1.2-EAS-1.3" by Horde.
> This is the first time I use both Horde5 and ActiveSync, so I have  
> no experience with versions prior to 2.0.4beta4.
> However, I needed to setup Horde multiple times, as I messed up some  
> pear stuff. This included adding and removing my "exchange" account  
> on my mobile several times, but the problem I describe in this mail  
> did occur after using the final setup for a few hours.

> Ok, enough prelude...

> The issue I am having are random emails which display multiple times

> It started with double mails, but later some mails are on the  
> smartphone three to five times. But not all mails are affected.  
> Maybe (or maybe not - I didn't keep track of the order of mails and  
> spam I removed) there were some mails in between which I marked for  
> deletion and later purged.

> In IMP and IMAP (checked against Roundcube) the AWS mail is found only once.

This is one problem that I've actually *never* seen. Even during the  
initial development. To further track down where/why this is happening  
we will need both the sync log and the imap log.

See http://wiki.horde.org/ActiveSync for how to enable the synclog.  
The imap log is enabled by editing imp/config/backends[.local].php
