sieve & websieve

[Manuel Streuhofer]

hi group. sorry to bother you with this offtopic (as it seems in first 
place) question, but i really could not get any information leading me 
to a solution for the problem described now:

i'm using websieve (v0.61h). everything works fine for normal users, but 
when i try to log in as cyrus (which is defined to be the admin) i get 
a 500 Internal Server Error. I managed it somehow to get the real Error 
directed to the Browser so i found out that something somewhen gives a 
"Error: Bad Protocol ........"

in my logfiles i cannot find anything so i'm wondering if anybody of you 
ever had a problem with this before.

thanks!
Manuel
