I have an old G4, and over time I got so annoyed by Mail and Entourage that I've just been using the Squirrelmail reader on my web host. Is there an OSX program you recommend that: --Has excellent spam handling --Is easy to configure --Is "light" i.e. loads fast and doesn't use much CPU --or is in any other way "best in class"? I know there are loads of reader programs out there--the problem is that there are so many that Googling has not been a big help. Thanks very much!
