如何在opendkim中为域电子邮件添加多个标志标头

Question

I have running opendkim in a server.
In this server I have two domains:

• the main
• my gateway for outgoing emails

Now in my signing table I add by each domain a sign DKIM .

I want to know if its possible add two signs to secondary domain.

I want this because when our server use ip of main domain, and MAILGUN do the same, add DKIM sign of mailgun.org and add DKIM sign to yourdomain.org , I too want to add main domain's DKIM signature and secondary domain's DKIM signature to emails of secondary domain, for arrive to received folder in gmail and not in spam folder.

Best regards.

Answer 1

I found solution, you must edit /etc/opendkim.conf and add MultipleSignatures Yes, next is edit /etc/opendkim/SigingTable *@primary.com mail._domainkey.primary.com *@secondary.net mail._domainkey.secondary.net

and add *@secondary.net mail._domainkey.primary.com

That is all :)
