2 Militers. DKIM and DomainKeys

[lioncub]

How to use two services in Zimbra? Use only one.

Ports:
DKIM 8891 (dkim-filter), DK 8892 (dk-filter)

How to register:

smtpd_milters =
    inet:localhost:8891,
    inet:localhost:8892

You don't, you only need to use openDKIM.

I want to use and DKIM and DK! To be in the mail header "DKIM-Signature:" and "DomainKey-Signature: "!
How to do it on Zimbra?
Postfix is able to do!

The simple fact is that you do not need both Domain Keys and DKIM. Domain Keys as a project is no longer active, read this from the DomainKeys project:

DKIM.org is actively maintained suporting the adoption of DomainKeys Identified Mail.

How to do it on Zimbra?
Postfix is able to do!

Zimbra uses Postfix, if you wish to waste time and cpu cycles implementing both protocols then feel free but my advice is still to use openDKIM.

Thanks...!
I installed dkim-filter for this. Advise which package to use dkim-filter or opendkim?

Where stores keys built-in dkim in Zimbra MinaMilter?

Zimbra doesn't store any keys for DKIM, you store them where the milter you've installed requires them to be.

Why do I need MinaMilter (listen port 7026)?

Why do I need MinaMilter (listen port 7026)?

You don't and I don't understand what you're asking, what's "MinaMilter"?

[lioncub]

If:

zmprov ms `zmhostname` zimbraMilterServerEnabled TRUE
zmmtactl restart

then:

# ps ax | grep milter

Why this process is needed?
