>From this report and your later mail, I think that you have a system
that is mixed etch/lenny or lenny as of some time ago. That is, you
made an upgrade when lenny was already testing and you still had
"testing" instead of "stable" in your sources.list. You changed your
sources.list to "stable" only later.

This creates a cascade of dependency complications that makes php, or
some parts of it, non-installable, hence making imp4
non-installable. You can try to downgrade to pure etch (put stable as
priority > 1000 in /etc/apt/preferences) or install php/horde/imp4
from lenny.
