cPanel not signing email with DKIM when using Cloudflare for DNS hosting

[fabienlege]

Hi,

My hoster provide me a cpanel access to mange my emails account. but for website performance reason, I use cloudflare for managing my domain DNS.

Everithing work great exept dkim signature !
- I've activated dkik in email > authentication
- I've copied DKIM txt record from cpanel to cloudflare
- i've tested my DKIM recork with Check a DKIM Core Key => success
- i've sending an email to DKIM Test - DKIM vérifier - DKIM validateur to check dmkim => FAIL ! no dkmi signature !

I've read every post about dkim+cloudflare on this forum, nothing help me to resolve the problem !

Has anyone successfully made DKIM work with Cloudflare?

Hi Lauren,

Thank you for your reply

Like I've said higter : no problem to find DKIM txt record in cPanel and integrate it in cloudflare.
dkimcore keycheck say me my dns are correct.

my problem is : my outgoing email are not signed by server.
result when I send mail to appmaildev.com :
DKIM-Result: none (no signature)

Yes I understood your issue but if the DKIM key is not added properly with CloudFlare it won't be signed, for example when you look at dkimcore that performs a DNS lookup of the record. This means that the TXT record is not able to be resolved which is why I sent you the articles that will resolve your issue.

Not sure if this helps but I had a similar problem which was related to a IPv6 issue. Cloudflare registers my domain as well as acts as proxy. My emails are properly signed with DKIM. I use default._domainkey.MYDOMAIN.com in my TXT entry on the Cloudflare DNS.

Log into cPanel and click on email->email deliverability. See if there are any problems you can have the system repair.

I recently solved a similar issue.
Solution: manually add a Message-Id (note not a Message-ID) header then connect and send an email.
cPanel WHM adds a Message-ID header and re-arranges the 'h' record in the DKIM signature which invalidates it, causing a DKIM:fail in the recipients mailbox.
