Installing SpamAssassin SNF4SA plugin for SNFServer involves the
following steps:

  1) Copy snf4sa.pm and snf4sa.cf to /etc/mail/spamassassin .

  2) Edit /etc/mail/spamassassin/snf4sa.cf to set the score to the
  desired value.  Setting the score to "10" would result in email
  detected as spam by SNFServer would be marked as spam by
  SpamAssassin.

The module writes the email message to a temporary file in
/tmp/snf4sa.  If this directory doesn't exist, the script creates it
with permission 777.  This allows both the script and SNFServer to
write to that directory.  If that directory already exists, ensure
that it has a permission of 777.
