Amavisd-new DKIM signing

Hi all
I've generated the the dkim cert, dns entry is done. In the configurationfile I've following:

enable_dkim_signing = 1;
$enable_dkim_verification = 1;
dkim_key('domain', 'mail201309', '/var/lib/amavis/db/domain');
@dkim_signature_options_bysender_maps = (
{ '.' =>
{
ttl => 21*24*3600,
c => 'relaxed/simple'
}
}
);

The problem is, that amavis does not sign the outgoing mails. What could be the problem?

Can you post the whole config? And what about postfix master.cf?

 

Hallo Florian
I've posted the main.cf and master.cf on pastebin:
http://pastebin.com/NV7dwkvb main.cf
http://pastebin.com/Gy5SH7iY master.cf

Which Amavis configfile do you wish to see?

Thx

Hallo Florian
The filterprocess will be as following on my server:
Postfix checks -> ESET MailSecurity -> Amavis checks -> mailbox
