[imp] IMP 3.2.1 very slow

Actually it doesn't just take ages to display the messages - IMP isn't
able to diplay anything and it's even not possible to login at all
(timeouts are set to 1/2 hour). This IS an imp/horde problem as we're
able to connect to that mailbox with other frontends. Speed of hardware
is hardly an issue as them machines are 2,4GHz P4s with plenty of RAM
and a fast disk-array.

I still think that Horde/IMP is a great piece of software, but it
looks like that there are some configuration where it's not working
well...
