SPF Checking

Traditionally, we’ve used SPF as a MailMarshal receiver rule set to log only. The anti social urge to blow off senders who don’t have SPF records has, so far, stayed well controlled.

Recently though, numbers of customers have been either playing with blocking and/ or putting up records. And it’s caused us a few minor problems. Sadly, half the issues have been crap SPF records. Sorry for yelling.

Graeme Slogrove, at M86Secuity posted this useful link to test your SPF records are correct:

Use it before you go live.

P.S. I know the picture doesn’t have anything to do with it, but it made me smile.
