 When working on email sending code you'll find yourself worrying about what might happen if all these test emails got sent to your mailing list. The solution is to use a fake mail server, one that acts just like the real thing, but just doesn't actually send anything out. Some offer web interfaces, feedback, logging, the ability to return specific error codes, all things that are useful for testing error handling, authentication etc. Here's a selection of mail testing tools you might like to try:

 Before running these examples in a web server, you'll need to rename them with '.php' extensions. They are supplied as '.phps' files which will usually be displayed with syntax highlighting by PHP instead of running them.
