How to drag (or import) Messages from Postbox

I took a shot after trying out Postbox and I really like it. Especially its search feature which is infinited better than Apple’s Mail.

That said, I’ve not figured out how to import my messages from Postbox into EagleFiler.

Your suggestions are much appreciated.
Thank you.

Please see Importing Mail From Postbox.

InfoClick from Nisus.com is very, very good for searching Apple Mail.
