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".
