CloseReview for Expiry Timestamp by Rob
Rated 1 out of 5 stars
It doesn't work at all for me in Thunderbird 3.1.10. There's no visible menu option for setting the expiration date.
The system as described is of little use. Setting the expiry relative to the current date, or being able to set the expiry to a specific date using a calendar would be better.
