Email not DKIM Signed (dkim=none reason="message not signed")

Hi Guys

I have been struggling to get DKIM working on my server. I have created the DNS records at cloudflare and have confirmed that they are correct but the messages don’t appear to be signed with DKIM when they are sent. Is there anything I can do to get this working?

Any help will be greatly appreciated.

Here is the message from my port25-com test: (I cant post links so had to remove all urls and email addresses)

==========================================================
Summary of Results

SPF check: pass
“iprev” check: pass
DKIM check: none


DKIM check details:

Result: none (message not signed)
ID(s) verified:

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.

==============================================================
Explanation of the possible results (based on RFCs 7601, 7208)

DKIM Results

none: The message was not signed.

pass: The message was signed, the signature or signatures were
acceptable to the ADMD, and the signature(s) passed verification
tests.

fail: The message was signed and the signature or signatures were
acceptable to the ADMD, but they failed the verification test(s).

policy: The message was signed, but some aspect of the signature or
signatures was not acceptable to the ADMD.

neutral: The message was signed, but the signature or signatures
contained syntax errors or were not otherwise able to be
processed. This result is also used for other failures not
covered elsewhere in this list.

temperror: The message could not be verified due to some error that
is likely transient in nature, such as a temporary inability to
retrieve a public key. A later attempt may produce a final
result.

permerror: The message could not be verified due to some error that
is unrecoverable, such as a required header field being absent. A
later attempt is unlikely to produce a final result.

Did you copy the DNS records from:

DNS records option in List mail?

Hi Eris

Yes I have copied the records from DNS in hestiaCP and replicated them in CloudFlare DNS.

DKIM enabled in the mail settings?

Yes, all enabled and showing that it should work…

Sorry, can only upload one image per post
DNS at cloudflare:

DNS in Hestia which has been replicated in cloudflare:

@eris Do you have any other suggestions? I feeling that exim may not be signing the message as it is sent, but not sure how to check or test?
