i was able to reproduce the problem with Outlook and OutlookExpress
by singning and encrypting an eMail and reading it with imp.

As i could not find any errors in any logfiles i added some debugloggin in
horde and imp. These debuging output indicates that there is a recursion
in horde/lib/Horde/MIME/Contents.php buildMessagePart which does not
exit. I guess after about 256 calls the script is stopped because of
execution time or memory limits.

Viewing an encrypted and singend message created by IMP or thunderbird,
buildMessagePart will only be called about 4-5 times.
