NAME
    Mail::SpamAssassin::Plugin::AccessDB - check message against Access
    Database

SYNOPSIS
      loadplugin     Mail::SpamAssassin::Plugin::AccessDB

      header   ACCESSDB  eval:check_access_database('/etc/mail/access.db')
      describe ACCESSDB  Message would have been caught by accessdb
      tflags   ACCESSDB  userconf
      score    ACCESSDB  2

DESCRIPTION
    Many MTAs support access databases, such as Sendmail, Postfix, etc. This
    plugin does similar checks to see whether a message would have been
    flagged.

    The rule returns false if an entry isn't found, or the entry has a RHS
    of *OK* or *SKIP*.

    The rule returns true if an entry exists and has a RHS of *REJECT*,
    *ERROR*, or *DISCARD*.

    Note: only the first word (split on non-word characters) of the RHS is
    checked, so "error:5.7.1:..." means "ERROR".
