One of the advantages of Mailinator and 33mail (two other services in this space) is that they allow you to receive email at your aliases for as long as you want, so they don't preclude password recovery. I think this service is somewhat hamstrung by the limited period when the temporary address is accessible.

There is no limit after registering the address. The idea was to cover temporary needs as well as providing the posibility to use it persistently.
