With TMDA you can make a 'dated' address which would allow anyone who uses that address to send you an email for a certain amount of time.
Example from http://tmda.net/config-client.html

This particular address expires on Sun, May 6 00:25:08 2001 UTC, which is exactly 5 days after it was generated. TMDA time intervals can be set in years, months, weeks, days, hours, minutes, and seconds. Once a dated address expires, messages sent there must go through the confirmation process. Use of strong cryptography insures that the timestamp can't be modified.
