[Dovecot] AntiSpam Plugin

Thu Jul 29 00:21:29 EEST 2010

  I did some closer research:

1. sa-learn script doesn't directly say something about "exit code 9" - 
it must be linked with another file which I wasn't able to figure.
2. while experimenting with drag&drop in Thunderbird PLUS playing 
arround with the configs I figured that my spam_count/ham_count values 
where changing as I was drag&dropping ... But it's still givin exactly 
the same erro as bevore when I try to move from INBOX to Spam folder:* 
[SERVERBUG] failed to send mail.*
And from a neutral folder to the as 'unsure'declared folder Virus I get 
the following Error in Thunderbird:* [CANNOT] Cannot copy to unsure folder.*
both times it exits exactly the same: "exit code 9"
... and worst: Mail is not being copied to the place where you dropped 
it but stays in its old place OR even worse: sometimes mail is not even 
only not copied but _lost_ .

I posted that one already, but here again:

The debug output I could find at /var/log/debug:
