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).

Send Later inserts several headers into scheduled messages and removes them when before delivery. When Send Later inserts these headers, they are on a single line in the message header, and the code for removing them later previously assumed that they would remain on a single line. However, some IMAP servers wrap headers when messages are saved into an IMAP server. As a result, some headers were being wrapped, and then Send Later removed those headers incompletely at delivery time because it left behind the wrapped text. The code has now been fixed to remove the wrapped text as well.
BUG FIX: Strip "Openpgp" header from scheduled messages during delivery
There's a constant arms race between Send Later and other Thunderbird functionality... Send Later needs to figure out what temporary, internal headers are saved by other Thunderbird functionality and remove those headers from scheduled drafts when sending them. The newest header I've discovered in this category is the "Openpgp" header, which Send Later now removes.
