Client's DNS is managed by Office 365. Office 365 helpfully creates an SPF record:

TXT @ v=spf1 include:spf.protection.outlook.com -all 1 Hour

Even extra helpfully, this is automatically generated by Office 365 and can't be changed apparently. All I want to do is include Mandrill, but it looks like I'm SOL.

Apart from moving DNS management to another host (which would be painful, but doable), have I got any options?

You have no option but to move the DNS records to another hoster.

Microsoft won't allow you to change the SPF record once it's created at their end.

Have additional SPF records you want to add for your domain? If Office 365 manages DNS for your domain, Office 365 handles spam filtering for you. You can't add another TXT record for SPF (spam filtering). To do that, you must set up your domain so that you manage the domain's DNS yourself at an outside DNS host (such as your domain registrar). Then you can set up the SPF record for the domain where you manage DNS for the domain outside Office 365.

  • Yeah, this appears to be the only option. Shame, as their DNS offering is actually pretty solid. This is one big limitation. – Dave Beer Apr 18 '16 at 09:39
