I have used Eudora in the past, when I was a PC user....I think back to those days now, and shudder....
I also have purchased this email application, and it had, for the most part, been sitting in my applications folder untouched. It was untouched simply for the fact that I was using the built in Mail application, which in my opinion is no where near as fast and efficient as Eudora. While upgrading to Panther, I wanted to see how well my installed applications were working. I ran Eudora, and it has been solid, reliable and quick on my flat panel, G4 imac.

What I really like about Eudora is the fact that you can tweak it to your heart's desire, and the Bayesian filtering in this client puts Apple Mail to shame. Spamfire is now history for me, as the filter with Eudora catches everything. As was stated in an earlier reveiw, you must let it know what is junk to you, and what isn't. After a time, this filter becomes extremely accurate.

Another thing I like is the fact that it is more aesthetically pleasing to the eye.
It works on all my email accounts, and trust me, I have tons!. Now, with the filter in place, I no longer have to use Spamfire before reading my mail. The only thing in my inbox these days is the mail I ask for.

I am very pleased and content with this version of Eudora and it is my default email reader. It costs a bit, but the features are worth it in my estimation.
