Hello, Please forgive me if I haven't found the thread that already relates to this. But I would like to be able to have messages I send expire after some time period. It looks like there was an add on "Expiry" that is no longer supported that did this to some extent. The functionality is available in Outlook and Gmail, which leads me to believe it is probably available in Thunderbird, but I am just not looking in the right place. I know that subscription services also provide this option but I would like it to be native to Thunderbird.

Thanks, Kurtis M
