[Kroupware] imapd problems with large messages

[George Staikos]

 Has anyone else noticed problems with imapd and copy large messages from 
local->server?  It seems to stall very often, it's very slow, and most of the 
time if the message is large enough (for instance, 5-10MB), it will just 
freeze permanently.  It seems to be freezing inside read().  I verified this 
with NS 4.x, KMail-HEAD, KMail-3.1.  They all freeze in ::write()  (or the 
slaves in the case of kmail).

This is with kolab 1.0 packages.
