I used 10MinuteMail exactly for what it is intended, creating a couple of dozen disposable emails over several days, using them at a website that required a fresh email address every time you used its otherwise free service. Then, wham, my IP address was permamently blocked from using 10MinuteMail. What good is this disposable email service if you can only use it a few times... and cannot depend on using it on a regular basis when needed. I searched an quickly found several other similar disposable email services online and use them without any problem. Forget this service and find another that you can rely upon.
