    The domain is your domain, right? The SPF of that domain is "v=spf1 mx a ~all" which should be ok when your IP is

    I think, your problem is "Please contact your Internet service provider since part of their network is on our block list (S3140)".

    Forgot to say we also for the affected domain set a specific SPF for the valid IP addresses
    v=spf1 mx a ip4:A.B.C.D ip4:A.B.C.D -all
