Found some spammers today with SPF records set up

  • Article

I came across some spam in my inbox today.  This company was pushing pump-and-dump stock spam for a medical company.  I saw that the company passed an SPF check.  That's odd, I thought.  A spammer passing an SPF check?  So, I decided to check out the SPF records:

dig txt watammatau.com

;; ANSWER SECTION:
watammatau.com.         1800    IN      TXT     "v=spf1 +all

 Sure enough, this spammer has set up a site and complied with SPF; they've set up a record simply for the sake of setting up a record.  Not that it helps them or anything, but it looks like they've set up a record for the sake of setting up a record.
