    Hi gamelofter

    The records and examples provided above will solve your issue, but you have to replace the example information with the correct information.

    A very simple SPF record that allows the MX only would be: -
    v=spf1 mx -all

    If the MSP spam system is your MX and you use this as a smarthost to route your emails out of the business this will be all you need, but if you have payroll and other web apps for instance that use your domain and send direct then you need to add these to the SPF record else they will fail.

    Hope this helps.

    Hi gamelofter

    SPF is a tricky thing; but here is a great example / guide for you......



    Main SPF Record
    DNS Record Type: TXT
    DNS Record Name: <Leave Blank>
    DNS Record Value: v=spf1 mx include:_spf.YourDomain.Name include:spf.protection.outlook.com -all exp=badguy.YourDomain.Name
    Notes: Allows you MX and O365 to send. Also allowes services in _spf.YourDomain.Name to send too. The info to why something has failed (exp=badguy) might need to be before "-a".

    _spf Record
    DNS Record Type: TXT
    DNS Record Name: _spf
    DNS Record Value: v=spf1 ip4:8.8.8.8/32 ip4:8.8.4.4/32 a:spam.YourDomain.Name -all
    Notes: Allows the listed IPs and A records to send

    badguy Record
    DNS Record Type: TXT
    DNS Record Name: badguy
    DNS Record Value: "The email from %{s} using SMTP server at %{i} was rejected by %{c} (%{r}) at %{t} because it failed the SPF records check for the domain %{p}."


    Hopefully this information helps and points you in the right direction.

    Regards
    Robin
