Ways to Prevent Spam
A good way to reduce spam is to have unique email addresses for each website. Most web hosting
companies offer unlimited amount of email aliases. Take advantage of
this feature. Use this instead of using a catch-all. Using a
catch-all email address causes problems because a lot of companies just
send emails out to dummy email addresses but addresses in which you
will have something set up, like sales@example.com.
For example, if you sign up on a message board that is at the URL
www.forum-example.com and your domain name is www.example.com, then
your email address to use would be forum-example@example.com. And then
you create an email alias in the control panel. (You might create this
email alias first just in case they send you a confirmation email.)
This way if you receive an email addressed to forum-example@example.com
but it is not from www.forum-example.com, you know they might have sold
your email address, traded it, or maybe they were hacked. You can
easily sign into your webmail and block forum-example@example.com. Of
course you might need to update your email address with
www.forum-example.com to another unique email address
(forum-example1@example.com).
Doing this won't prevent spam, but it will cut back on a lot of spam.
