Hello,

 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:

DKIM Signature

Message contains this DKIM Signature:
DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/simple; d=mymotors.in;
