Securing PHP Contact Forms

Pixel Acres has a great writeup on securing PHP contact forms. Using header injection is a huge concern for developers and site owners as it allows spammers to abuse your web forms to send out their nasty SPAM.

The writeup covers the whole process to give you a great understanding of how it works and how to prevent it.

  • How they do it
  • The Solution
  • How to tell if your form is being exploited
  • What to do if you’re still getting annoying e-mails

The writeup ends with a couple links for further reading that I suggest following if you want to completely understand - or Grok it.
