I'm changing over from Outlook 2003 (PC) and I have a Thunderbird (OS X) question: In Outlook 2003 I have unchecked "send immediately when connected". This is because I frequently forget to attach a document or remember something after I hit "send". Having the "send/ receive" set to 10 minutes allows me to fix emails. Is there a way to do this in Thunderbird? All my emails seem to get sent automatically, and I can't find the setting to delay them until the send/ receive time.
