Trying to debug this further and wondering if it was the caching issue
that is associated with the could not generate email list error
everyone else is reporting, I logged in from Chrome  - which gave this
error (Firefox just gives a blank page)..

Server error
The website encountered an error while retrieving
https://mymail.mpingwe.com/services/portal/index.php. It may be down
for maintenance or configured incorrectly.
Here are some suggestions:
Reload this webpage later.
HTTP Error 500 (Internal Server Error): An unexpected condition was
encountered while the server was attempting to fulfill the request.

Still the horde.log only shows:

2011-11-04T14:16:30+00:00 NOTICE: HORDE4 [horde] Login success for

There is NO error in the apache error logs though.

I'm still not convinced this is actually a Horde problem - for the
moment it's confined to one user - but I'm stuck on how to
troubleshoot this further.
