I don't know if it matters but your email contains several unicode 
characters where only ASCII schould be used. Maybe this is causing your 
problems. Make sure you use an ASCII editor when editing the config 
files and use all ASCII host names. In the file above the hosts 
192.168.2.100 and 192.168.2.2 (aka 81.202.40.1) had 'problem' names.
