OpenDKIM Implementation : domainkeys=neutral (not signed), dkim pass ?

[vavai]

Hi,

I'm implementing openDKIM on Zimbra+SLES 11 SP1. dkim pass OK but domainkeys marked on the recipient (tested on Gmail and Yahoo) as neutral AKA not signed.

mta1079.mail.sp2.yahoo.com from=domain.web.id; domainkeys=neutral (no sig); from=domain.web.id; dkim=pass (ok)

I have add openDKIM code into /opt/zimbra/postfix/conf/main.cf as below :

smtpd_milters = inet:localhost:8891
non_smtpd_milters = inet:localhost:8891
milter_default_action = accept

But message doesn't signed anyway. I could telnet to 8891 and confirmed that openDKIM working correctly.

Any help greatly appreciated.

DomainKeys check is implemented by using dk-milter. You will need to install and configure the dk-milter program.
You can use the public / private key pair from openDKIM in dk-milter.
