Is it even possible? Could there really be one way to get e-mail without spam let alone 3 ways? You bet there is and Mike, at Web Worker Daily, has posted them on his blog. They are kind of like a disposable phone, use it a few times and toss it. They are just in the event that you want to leave an e-mail address on one of those sites that could very well generate a flood of spam back to you.  Mike gives 3 solid and effective ways to dodge the spam bullet.

Use plus addressing: This one works with GMail and
many other providers. If your actual address if Chumley@gmail.com, then
mail to Chumley+foo@gmail.com will get to you, as will mail to
Chumley+43frog@gmail.com, or an address with just about anything else
after the plus sign (you may be limited to six characters). If the
particular plus-address turns into a spam magnet, create a filter to
throw incoming mail away forevermore.

"Use a disposable mail service: Try Mailinator, dodgeit, or PookMail
(there are others of the same ilk, but those are the best known). No
registration required; you just pick an address like
SpotTheWonderHamster@mailinator.com and check incoming mail through
their web interface or via an RSS feed. Drawback: anyone who guesses
your address can check your incoming mail too. These services are great
when you want to get one piece of mail from someone like a used car
salesman who you never want to hear from again in the future.

Let Contactify do the work:  Instead of putting your email address on your web site, take two minutes and sign up for a contact form at Contactify.
They’ll give you your own dedicated link to a captcha-protected contact
form on their own site. Readers who want to send you a message fill out
the form, solve the captcha, and click OK; Contactify forwards the
message to your email address, which they never hand out. If you don’t
have the skills or software to implement your own captcha, this is a
free way to get the same level of protection from address harvesters
and spamming robots".
