Why use automation?

We’ve seen that if we use include statements in our SPF record then we could all too easily exceed the hard limit of ten DNS lookups, suddenly causing all of our emails to start going into peoples’ spam folders. That’s our regular business emails, our marketing emails, our payment confirmation emails – everything.

So we know that we want to flatten our SPF records to prevent this from happening, but we can’t possibly keep up-to-date with the changing IP addresses that all of the email companies might be using.

Automation to the rescue

With proSPF you create a record that looks like a regular SPF record, but instead of creating it for yourdomain.com you create it for prospf.yourdomain.com. It doesn’t matter how long this record is, or how many DNS lookups it contains, nothing will use it except proSPF.

You then set your actual SPF record at yourdomain.com to be as follows:

v=spf1 redirect=yourdomain-com.secure.prospf.net

We’ll tell you exactly what this will be as part of the sign-up process

Every hour the proSPF engine reads your record at prospf.yourdomain.com, looks up the SPF records and IP addresses in all of the include statements (including all of those nested ones like spfd.protection.outlook.com!) and publishes a completely flattened SPF record at yourdomain-com.secure.prospf.net. This SPF record contains only ip4 and ip6 statements – so your DNS lookup count is exactly zero. Perfect.

What’s more, you never have to worry about Microsoft adding a new block to their Office 365 range, nor MailChimp updating their list of email servers – those get updated every hour by the proSPF engine.

All you have to do is maintain your list of authorised email partners at prospf.yourdomain.com, not worry at all about how many DNS lookups that entails, and leave the rest to us.
