In reply to PW. each domain defines the key it uses. given the signing table mechanism, there's no good reason to use the same keypair for multiple domains.

In reply to greygeek. this isn't ssl. they key is simply used by recipients to validate the signature, so it has nothing to do with your ssl key, and since the pubkey is given in dns, there's no reference to the intermediate CA.

In reply to Robyir.

Hi Robyir,

When we install postfix then ‘/etc/postfix/main.cf’ file is created automatically.

Could you please check your postfix installation once ?

cat: /etc/postfix/main.cf: No such file or directory

I’m out of ideas. Any help would help. what is the selector i add to my dns.. for instance.. when i do a test both show vaild records so i’m not sure why i keep getting dkim=neutral (bad format) header.i=@domain1.com header.s=default header.b=lQ1YkIEB;

‘domain1._domainkey.domain1.com:v=DKIM1;k=rsa;p=MIGfMs…………………………..

‘domain1.com._domainkey.domain1.com:v=DKIM1;k=rsa;p=MIGfMs…………………………..

Ok I found the problem why it wasn’t signing, but now when checking the header in e-mail it says invalid format dkim-neutral

The mail gets sent but it is not signed . The logs don’t show anything about dkim either. Dkim is running so i’m not sure why there are no errors displayed
