Update: I have been using Mail.app for a few weeks now, and I wrote an Applescript to add tasks in a "Follow Up" folder to OF and it works great.
BUT... it is clear that Mail.app has some issues. Its not a great application anymore. I have attachments missing which is the most important issue. I really dont want to use Mail.
Postbox seems like the best, but no Applescript support.
If I run both then I double my bandwidth usage... since using Mail over Gmail I already passed my bandwidth for last month, so I wont be using two email clients together, downloading emails twice. Then because I archive email to another folder it in effect re-uploads it to GMail IMAP. So I already have twice the bandwidth usage for each email due to download and re-upload, then if I use Mail and Postbox then it's 4 x the bandwidth compared to just GMail!
So I will try to stick with Mail and just hope OF get up to speed like other common applications and add tasks via email to the server version we sync with. then I can use whatever mail application I want, and not forced to use Mail.
