I used Emailer for the past many years - even in classic, until I began using Verizon's DSL service and needed outgoing authentication. Looked closely at Apple Mail and Powermail, but realized that I already had Entourage sitting on my hard drive. I have been very happy with it over the past 9 months. The interface is really clean, although the program is a little sluggish with OS X on a 400 Pismo, but not too slow. Still, for some strange reason, I keep my eye on Powermail....
