    Question rejected by smtp? what is this?

      This report relates to a message you sent with the following header fields:
        Message-id: <[email protected]>

        To: [email protected]
        Subject: Quote
      Your message cannot be delivered to the following recipients:
        Recipient address: [email protected]
        Reason: Remote SMTP server has rejected address
        Diagnostic code: smtp;550 See (#5.7.1)
        Remote system: dns; (TCP||56303||25) ( - Welcome to Qmail Toaster Ver. 1.3 SMTP Server ESMTP)
    I go to that link and it says this

    Code: rejected a message that claimed an envelope sender address of [email protected]. received a message from ( that claimed an envelope sender address of [email protected]
    However, the domain has declared using SPF that it does not send mail through ( That is why the message was rejected.
    The SPF on my domain is this:

    Code: IN TXT "v=spf1 a mx -all"

    I sent it via my ISP as I have to use their smtp server.

    How would I correct this?

    Should I just add this to the spf record?

    No you would add "" assuming your isp has a SPF record for their domain.

    It doesn't look like OptOnline publish an SPF record. As such you'll need to identify all their outbound mail servers (which are not necessarily the same as the one you connect to for sending mail) and list those in your SPF record.
    I think the server saw what was required of it and just committed suicide instead.

    You will need to contact Optonline and ask them what IP address their outbound mail server sends out messages from. Tell them that you are needing to know the IP address so that you can properly set your SPF record. They should understand what you are after.

    You may also want to ask them why they do not have an SPF record published for They can set an SPF record on (or a subdomain, i.e. which users can then use to include in their won SPF record. Then any IP changes that they make, they just have to make the changes to the SPF record and any other domains that are using the include will also be updated.
