It works simply and well.
I would add:
- a drop-down calendar that lets you select expiration on a particular day, not just 1 or 2 days/weeks/months after the email's date
- selection of time for expiration, not just the time of the email
- a choice to move expired emails to another folder (ie Trash) instead of deleting them completely
- a choice to (re)move emails on a regular basis instead of waiting for the folder to be compacted
- it would be nice if you could use expiration date as a search criterion. I tried adding X-Expiry-Date as a custom header, but t-bird search didn't seem to understand it was a date, and it didn't work
