SpamAssassin Rule: DKIM_ADSP_ALL

Standard description: No valid author signature, domain signs all mail

Explanation

The sender's domain says that it uses DKIM (http://www.dkim.org/) on all email, but no valid signature was found.

That suggests that the message might not have originated with the purported sender.
