How can email forwarders prevent SPAM or unwanted mail?
Imagine you visit a website that offers an interesting FREE report about something. You do not want to continue to get mail from them, but only this one time FREE report. What you do is to go to Cpanel create a forwarder like this: domainname-com@my-domain.com and set it to forward to your POP3@my-domain.com email address. Then you subscribe with the ‘domainname-com@my-domain.com’ email address and after getting the report you go back to Cpanel and delete the forwarder. Another solution that I use a lot is when someone like my insurance company or some other company ask for my email address then I create one forwarder with their name. E.g: insurance-company-name@my-domain.com and if I start to receive spam on that email address, I know exactly who has given away my email address. Furthermore I tell the one I give the email to, what I do, so that they understand that if they do it, I will probably look for another business to deal with.
