z-push with Nokia E90

[Gavin McCullagh]

Hi,

we've been experimenting with the Z-Push plugin.  It's really great, thanks
so much to those who have put the work in.  The recent addition of syncing
shared folders works great.  We have two HTC Desires working nicely with it
and I've previously seen the iPhone work well too so we plan hooking one or
two of those up shortly.

We have a Nokia E90 also.  The phone itself doesn't support ActiveSync but
the add-on application "Mail for Exchange" from the OVI Store adds this
functionality.

I've tried to get this to work for syncing contacts and calendars using an
empty test account, but each time I do I get "System error. Try again
later" from the phone.  

In the z-push logfile, I can see this feedback:

Can anyone suggest what might be going on?  Is there some debugging I can
do which would help?  At a guess, if we can get it working, that would be
for all phones which use the "Mail for Exchange" app.

Thanks in advance for any suggestions,
Gavin
