I tried to sign all outgoing messages using DKIM but did not seem to succeed. DKIM check was OK but DomainKeys check was neutral. I then tried to send email to yahoo account and did not see the verification sealing within yahoo mail interface. could anyone please assist me on how to make this domain key check successfull?

below are the results of the test

NOTE: DKIM checking has been performed based on the latest DKIM specs
(RFC 4871 or draft-ietf-dkim-base-10) and verification may fail for
older versions.  If you are using Port25's PowerMTA, you need to use
version 3.2r11 or later to get a compatible version of DKIM.
