How hard would it be for Apple to include “Send Later” and “Send Queued Messages” menu items in Mail.app, I wonder? Being a dialup user half the time, I’m not always ready to fire off my messages from the hip, so right now I need to hit the Send button, wait for a dialog, select Send Later, then restart Mail.app when I do connect so it sends automatically.
A message queue should be a fairly basic feature, and I’m happy with Mail.app otherwise.
