How can I sign multiple domains using dk-milter so that each domain would have it's own different domainkeys signature.
I've already done this for DKIM using openDKIM (http://stevejenkins.com/blog/2010/09/how-to-get-dkim-domainkeys-identified-mail-working-on-centos-5-5-and-postfix-using-opendkim/) and now I have a different signature for each domain. So no I need to do the same for DomainKeys using the same signatures as DKIM. Doing if for one domain is simple, but for multiple domains I can not find a solution. Each domain already has the public key in the DNS entry from DKIM, so it differs, stopping me from using a single a single signature for all domains if that would be possible.
Here is my dk-milter config file:
USER="dk-milt" PORT="inet:10035@localhost" SIGNING_DOMAIN="domain.com" SELECTOR_NAME="default" KEYFILE="/etc/mail/domainkeys/keys/domain.com/default" SIGNER=yes VERIFIER=yes CANON=simple REJECTION="bad=r,dns=t,int=t,no=a,miss=r" EXTRA_ARGS="-h -l -D -i /etc/mail/domainkeys/internal_hosts" MILTER_GROUP="dk-milt"
