There are probably as many strategies to stop spam as there are to send it. For the article below, I’m only talking about working with YOUR email address ([email protected]), not blacklisting or whitelisting THEIR email addresses ([email protected]). Here are two main strategies.

Blacklist
Allow all mail to come in to any email address with your domain at the end of it. For example, set up your default email address ([email protected]) so that you get all email to your domain. You’ll get [email protected] and [email protected], but you’ll also get [email protected] and [email protected]–those last two are favorites for spammers to guess.

This strategy works for a while, but the spammers will get more creative and start with [email protected] and [email protected] and you’ll be battling a giant.

Whitelist
A more extreme yet more effective method is whitelisting. You block every incoming possibility, but allow the ones you use ([email protected], [email protected]). If you sign up with Amazon and you used [email protected], you can set up a forwarder to allow that address. Yes, it’s more time consuming to add those you use, but it’s a much easier battle.
