sitebot exclusion from implicit ssl

Hi,

im using the beta5-8-5r registered version and i have a problem excluding the sitebot or any user from implicit ssl. i tried the solution in the kb:

Require_Encrypted_Auth = !-sitebot *

but it doesnt work. the rest of the configuration is:

Require_Encrypted_Data = !* (whether this is on or off, the sitebot cant connect)
Certificate_Name = x.x.x.x (ip)
Explicit_Encryption = False
Encryption_Protocol = SSL3
Min_Cipher_Strength = 128
Max_Cipher_Strength = 128

When i try from an ftp client to connect normally (without implicit ssl) it doenst connect, but when i use implicit it works normally (So it isnt a problem with the certificate or the sitebot account).

what am i doing wrong here ?

thanx for your help in advance
