Wait... so you are selling free email addresses? that you don't even control? And you don't think 1&1 searches the internet for people selling email address?
(from Terms and Conditions)
8.13. You agree and warrant that you shall not resell or redistribute the mail.com Services or any part thereof, including but not limited to your mail.com e-mail address, or use any unauthorized means to modify or reroute the mail.com Services (or to attempt same).
I hope you realize that simply by typing those email addresses in a public forum means there is a pretty good chance you'll lose them.
If you're not interested, simply don't post and save precious time. Thanks
