It is amazing that there are people who seem not to know this. If you have Thunderbird setup on your system, then install Postbox. It will transparently inherit your Thunderbird settings. It was astonishing to read the post above that claimed that Postbox is like an enhanced version of Mail. More power to those for whom Postbox is worth the fee. However, I have never seen the value that Postbox adds to Thunderbird.
