About this Add-on
You can specify a specific time and date, or click "15 mins later", "30 mins later" or "2 hours later", or click "Put in Outbox" to get the built-in Thunderbird "Send Later" functionality (i.e., copy to Outbox).
For additional information, see the user guide.

Send Later uses SugarJS by Andrew Plummer. Thanks Andrew!

Thunderbird’s local folder storage format keeps deleted messages on disk, but invisible to the user, until their folder is compacted. Usually this causes no trouble, but occasionally Thunderbird corrupts a local folder and loses track of messages which messages were deleted, causing them to “magically” appear in the folder again. In most cases, this causes no further harm than deleted messages being resurrected, an annoying nuisance but not a huge problem.
However, when Send Later is being used, and when the folder this happens to is the user’s Outbox folder, it can cause a big problem: messages that were previously sent with Send Later can be resurrected and resent. If it has been a long time since the Outbox was last compacted, a lot of messages can be resent. This is bad.
Send Later now guards against this by by automatically compacting the Outbox folder whenever Thunderbird finishes sending its messages and it is visibly empty, i.e., the only messages remaining in it are invisible, deleted messages.
Make locale-based first-day-of-week work in calendar pop-ups
There is a bug in Thunderbird which was preventing the calendar pop-ups displayed by Send Later from starting the week on the correct day, in locales where that day isn’t Sunday. See https://bugzilla.mozilla.org/show_bug.cgi?id=516796. Fortunately, there’s a workaround for this bug, which has now been implemented in Send Later. Therefore, if your computer starts weeks with the correct day elsewhere, it should now do so in the Send Later calendar pop-ups as well.
Miscellaneous minor changes
The command key for the “Close” button in the dynamic function editor is now Ctrl-W in every language, as it should be.
A bunch of button access keys (i.e., the letters you an type with Alt to activate the buttons) have been fixed.
Use the Unicode ellipsis character instead of three periods. Also, use Unicode quotes instead of ASCII double quotes.
Be more consistent about the add-on name in translations, i.e., decide for each translation whether the add-on name is going to be “Send Later” in English or a translated version, and carry that decision throughout the entire translation.
Update the URL of the user guide because it’s got SSL (https) now.
The Development Channel lets you test an experimental new version of this add-on before it's released to the general public.
