Hi Ralf,

played around with it a bit. There is another thread here which indicates people couldn't get it to work. With the latest and greatest it seems to have some query issue:

[...]
Apr 12 09:22:04 spectre postfix/smtpd[18355]: warning: access table inet:127.0.0.1:10027 entry  has empty value
[...]

Regards
Thomas
