Re: [dkim-ops] no signature data on the log

Hi Murray,

As far as I understand, although we applied DKIM according to the relating
RFC, library and etc. Yahoo is feeling free to process signed emails that we
sent. I found the following program, may be after we registered the
following program, Yahoo will populate the DKIM symbol and tooltip besides
our signed mails sent to Yahoo.

Thank you again for your valuable contribution and help. I appreciate really
your response.
