That seems to be correct.

How to do?
My debug file is within one week just 9 MB, whilce my incoming is 5 MB,
and most of the entries are these.
BTW, is incoming and debug used or just info? I mean can I delete them?
In the pending folder is the pending message, which the full spam
header. I would like to send these all to spamcop. The idea behind is,
that rbl is faster than tmda, and would refuse the message first (for me
and many others too).
Is there an easy way to do that ;-)
