mail server with opendkim


 I have configured sendmail server for my vps, with godaddy dns. I'm trying to setup opendkim signature for my mail server, but it seems broken somewhere.

I'm checking emails with tools where it shows :

DKIM Information:

Please suggest how to cross-check and resolve this.

This should be a single string:
"v=DKIM1; k=rsa;" DRAGON_HERE "p=MIGfMA0GCSqG.... "

hooouty why its not working

You have weird MX record for that domain that serves no function at all.

Yeah, that's what i'm thinking too. So i how to set one ?

I purchased a domain like this mymotors.in from godaddy

i tried to setup cname for mymotors.in to mail.mymotors.in , but refusing to list i hope.

Whats should i do here.

Puspharaj SelvarajSr.System engineerAuthor Commented:
now i corrected it. set CNAME for it

CNAME does not work with mail at all.

Use some online DNS checker to point you to mistakes. Your DKIM is fixed and my help ends there.
