I need a temporary email to register on one web service and not to receive spam later. But the thing is that they block emails from all known temporary and public email services. Is there a temporary email provider which registers a random domain, provides an email for temporary use and then cancels the domain?

The only service I can think of is 10minutemail.com. However, like the name suggests, you only have the address for 10 minutes. It is great for registering for sites and/or services, but obviously, do not expect to get communications at a later date.
If you want to always communicate with this company and just not get spam, take a look for another free email address which happens to be new / unknown - e.g. type free email hosting in to Google and start looking at page 10!
