I recently changed ISPs and deleted my old ISP account in Mail preferences. However, when I create a new email, it still defaults to trying to send via my old ISP in the little 'account' pane below the subject line in a new email. Is there any way I can get rid of this short of re-installing Mail, and if I have to reinstall Mail, do I do it from my 10.4 dvd and then have to re-run all the updates to 10.4.6 in case there's stuff in the updates that is relevant to Mail? Also I keep installing Mail on the icon bar but when I double click on it, OSX has forgotten where it is and I have to double click on it from the applications folders. Are there some files I can just delete to clear all these problems without having to re-install Mail?
