    what does this mean?

    Email error:

    [email protected]
    (ultimately generated from [email protected])
    SMTP error from remote mail server after RCPT TO:<[email protected]>:
    host []: 550 Message blocked due to SPF failure. See for more info.

    Is it saying my server blocked incoming mails, or the sending server is the problem?

    Seems like you've been blacklisted perhaps, and you need to either update your SPF record, or create one.

    How do I update my spf record? I don't understand

    I think your email has been recognised as a spoof email by the SPF system

    You do not have a valid SPF record setup.

    You can check this by typing,

    dig txt

    You can setup a spf record by using something like

    "v=spf1" "ip4:main ip" "a" "mx" "~all"

    Or even more broad

    v=spf1 +all

    I suggest you use however to generate yourself a better one.
