    If I send an email from a domain with PHP

    Can you expand on this a bit more? Are you using some sort of script or blog or something else?

    Yes, I used an PHP delivery method from my forum system.

    You should use the SMTP option instead, this way, the email used is your exact email that you use in the settings.

    Thanks @Infopro but it is not an option in my case. There are circumstances in which I must use php.

    I'm curious enough to ask what they are. As the message in your screenshot shows, "reliability may vary" using the PHP option. These days it's important to authenticate to prevent issues like you're having.

    That's not a valid reason to not use SMTP, IMHO. ;) Why not configure your forum to use SMTP email with a valid email address and give it a try?

    I agree 100% with @Infopro, there is really no good reason in this day and age not to use an authenticated SMTP connection to a valid email address to send mail from a PHP script, especially since your forum system already supports it as shown on your post for full details

    Right! I congigured with SMPT, but DKIM fails. This is the information about: - I have an external SMTP mail service that works perfectly in webmail an in mail manager. DKIM Pass - But in my forum, with SMTP de DKIM fail.

    This is the forum developer answer: [QUOTE]Hello, Im not sure on what your hosting company is referring to here, but DKIM is controlled by the server, not the application. We simply send a mail through SMTP to the SMTP account.
    My mail company tested and all works perfectly. Can the problem may be in some cpanel configuration in my server?

    We're probably going to need some additional details about this comment, then.

    You're right. I have contracted a hosting mail service (external to my dedicated server). I use it via Cpanel webmail, and I also have it configured in my Mail Manager with the SMTP data: host, port, SSL, user, pass. Everything works correctly, and messages are validated through DKIM. The problem is when I use the mail service through my server, configuring the SMTP data in my forum system. It is here when validating DKIM does not work. 1.- On my server, I have the DKIM key configured in CPanel, and also in the DNS of my server provider. 2. - Mail hosting company, checked everything and it works without problems. 3.- Forum developer, say that "...DKIM is controlled by the server, not the application. We simply send a mail through SMTP to the SMTP account." 4.- I have my website with cloudflare, but I have DKIM in the cloudflare DNS and also, with cloudflare off, the problem continues. 5. - In my server company DNS interface I can"t paste the same DKIM key as in Cpanel, so they say say that: "TXT strings over 255 characters must be divided into several strings and indicated without line breaks. Please copy this record into your zonefile:(DKIM key provided for them)" 6.- - Mail hosting company say that: "If we make a query of the DKIM registry of your domain, we can see that it returns the following:(MY DKIM key) if we check the DKIM record assigned to your domain in CPanel, we see the one we provide in this line:(My DKIM key with quotation in middle) If you analyze it in detail you will see that there is a quotation in the middle of the line, which breaks the DKIM record. Fix this, please" "But I can"t find de DKIM key with quotation in any site!

    Where is DNS for your domain hosted? On your server or at the registrar? It sounds like DNS is hosted at the registrar/remote and the DKIM you're updating isn't being reflected. If it is pointed to your server you might try the following: 1. Check the DNS zone file for an additional record 2. Go to cPanel>>Mail>>Authentication - > disable then re-enable the DKIM

    Hello, I have my DNS in: 1.- Cloudflare 2.- My server provider:hetzner.de 3.- In my domain registrar I have de Cloudflare Nameservers. 4.- In My CPanel server I have de DKIM generated by Cpanel (I deactivated it and reactivated)
    . Check the DNS zone file for an additional record

    Sorry, what do you mean?

    I didn't realize you'd stayed with CloudFlare - they have special instructions for adding DKIM and they have instructions on doing so which can be found here:

    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.
