[AMaViS-user] bloking dkim signed verificaiton failed

[Luis D. L. Q. <lui...@gm...>]

Hi everyone,

I'd like to block this:

Jan 12 14:23:57 laposte amavis[27651]: (27651-06) dkim: FAILED Author+Sender 
signature by i=dag...@do..., From:
 <dag...@do...>, a=rsa-sha1, c=nofws, s=domain.com.mx, 
d=domain.com.mx, ORIG [10.200.0.1:41420], fail (
message has been altered)

domain.com.mx is my localdomain and this is aborder antispam, no emails from 
domain.com.mx to domain.com.mx should go thrugh this server.

I'd like to give a +10 spam  grade if DKIM failed, is this a amavisd task or I 
should configure SA DKIM verification rules to do this?

TIA
