Outgoing only sendmail with domain key signing

Hello Friends,

I have setup an outgoing sendmail server. It helps take off load from the primary one
and now I have to sign mails with domain key.

The problem I am facing is that the dk-milter will not sign mails meant for the primary mail server ( Or you may say Actual Domain ) since it itself is running under a different machine name. If I setup the machine name of this outgoing server same as the primary one then mails become dead letters for the same domain due to user unknown errors as the actual mail accounts exist on the primary machine. For mails to external domains this setup works.

Can anybody suggest a solution for this.

Thanks

 

why dont u switch to DKIM ? DK is depreciated.

 

Hello Friend,

Excuse me for such a later reply.

I am using DK instead of DKIM due to its dependability in one
of the proprietary servers handling mail.

I have setup masquerading sendmail to divide load from the main server.

The problem is that DK does does not sign the mails. Going through Google
I have come to know that I may have to us DomainPortOptions and use sendmail as MSA.

I have confusion that can one run two sendmail daemons on one machine and forward mails from one daemon to another.

For EX masquerading daemon forward mails to another daemon for DK signing.

Can you help in this regard.

Thanks for your time.
