| filter-senderscore setup 
+-----------------------------------------------------------------------

To use the SenderScore filter, you must declare it first in your
OpemSMTPD configuration. 

Edit the @PKG_SYSCONFDIR@/smtpd/smtpd.conf file to declare the filter:

  filter "senderscore" \
  	 proc-exec "@PREFIX@/libexec/opesmtpd/filter-senderscore [...]"

The following options may be passed to filter-senderscore:

-blockBelow 10
block at banner sessions score below 10

-junkBelow 70
add X-Spam header to sessions below 70

-slowFactor 1000
delay by up to 1000 ms (proportionally to reputation) each reply

See filter-senderscore(8) man page.

Then add the filter to each listener that should be filtered:

  listen on socket filter "senderscore"
  listen on $ipv4 [...] filter "senderscore"
