An automated way that mail sits in an Outbox until I hit a Send All button, and that prompts me to send unsent mail when I quit Thunderbird. Better yet, I'd love the opportunity to just set an automatic timer so all my messages sit in the Outbox for, say, 1 hour. The reason I want this is that I send hundreds of mails every day and once or twice a week, I make some horrendous mistake that I realize within seconds after hitting Send - so I need a place where stuff sits for a while, just in case I made a mistake. Example of an implementation: Entourage has Send Now and Send Later buttons in the toolbar and a Send/Receive button. If you press Send Later, mail sits in the Outbox until the Send/Receive button gets pressed. I believe Outlook has a similar feature. This is different from: - The current File>Send Later feature because (1) it's impractical to go to File>Send Later each time and (2) it's also impractical to have to remember to send those messages at some later time (by going to File>Send Unsent Messages); - The Offline extension which (1) again, requires some intervention on my end (going offline, then going online periodically and (2) doesn't seem to work for me right now (using TB0.2): messages sit in my Unsent folder forever if I go back online by clicking on Get Mail, even tho the preference says to deliver Unsent messages when going online (I have to go to File>Send Unsent Messages to deliver them). I have pledged $100 on Sourcesupport to get this feature implemented: http://www.sourcesupport.org/?project=45 And there's a discussion on Mozillazine about this http://forums.mozillazine.org/viewtopic.php?t=24415 (4 people supporting the idea).
