 The interesting part is that all works well here on a different server:
 same horde (2.2), same imp (3.1), same php (4.3.0); different apache
 (2.0.44 vs. 1.3.27) and OS release (Solaris 9 vs. 8).

 Things like this are my biggest grip with horde, and php/php apps in
 general: unpredictability. Every time one component is upgraded, something
 is almost guaranteed to break. Not exactly what I call mature software.

 Don't get me wrong: I like imp/horde, and I gladly provide them to my users
 as alternative to other mail apps, but it can be very frustrating at times.
