    I have finally managed to send emails to recipients but not all of emails are being delivered to all addresses.

    Using the source of a successfully delivered email I suspect the following:

    Authentication-Results: ukmail.iss.as9143.net;
    spf=softfail (198.91.80.251;mywebsite.com);
    dkim=pass header.d=mywebsite.com;
    dmarc=pass header.from=mywebsite.com (p=none sp=none dis=pass);

    "spf = softfail"

    SoftFail means the IP address may or may not be authorized to send from the domain.

    • The mailbox provider will likely mark the message as suspicious, however, they will still accept it. A softfail does not necessarily cause deliverability problems by itself because mailbox providers rely on other data points to make a filtering decision.
    • Ensure your SPF record is up to date with your sending server or IP address information.

    Checking SPF record via DNS:

    TXT v=spf1 +mx +a +ip4:198.91.81.5 ~all

    [​IMG]

    Analysing SPF:
    [​IMG]


    "all SoftFail Always matches. It goes at the end of your record."

    SPF Failed for IP - 212.54.57.73

    212.54.57.73 = Zwolle Ziggo B.v. based in Holland.

    Also
    "DKIM Signature Verified : Signature Did Not Verify"


    Public and private key : "The receiving email system applies local policies based on the results of the signature test. For example, the message might be deleted if the signature does not match."

    Not sure where to go from here to fix this issue.

    I never got so in-depth with that kind of stuff myself.
    i mostly just use gmail for my email needs besides a default one on my site.
    if it is server related you know how well that will go right now.
    at least until they get to fixing things.

    but didnt you say you use cloudflare as well ?
    from what i saw about SoftFail's or SPF authentication failures,
    they mention dns settings, so it may be an idea to look at cloudflare.
    (i know screwing with dns settings is a pain, for me it always is)

    if you setup cloudflare from the cpanel id be wondering about that to.
    considering all the other failures on some servers right now.
    (fortunately i haven't noticed any issues on mine yet)

    The DNS propagation is testing my patience.
    Using cloudflare for the website only, not the emails, as the protocol is bypassing the proxy and going straight to x10hosting.

    It appears it just takes time for the emails to filter through as they are immediately flagged for spam and/or appearing not authoritive/genuine.

    The shared 198.91.81.5 address by x10hosting has perhaps triggered a few red flags in the past by various major email handlers.

    Genuine emails are being dropped/deleted even before they reach the recipients inbox/junk folders.

    Try to check your DNS settings via mxtoolbox and see if the same with your setup.

    The DNS settings were always fine.
    I only had to understand the SPF format to fully integrate it into the emails.
    All working great now.
    Everything passes.

    I think that this Ip 212.54.57.73 is using your domain address as an email header. Is this one of your sending email server? if not it is unuthorised hence you see SPF failed authentication

    No, it has nothing to do with that IP.
    As I said previously I managed to figure it out and have the SPF "pass".
