Well I’ve made the switch over to PowerMail 4.1.1. Entourage started to have too much bloat. I was using iCal and Entourage’s message database was over 40 Mg, PowerMail’s was 4 Mg with an Attachments folder of 14 Mg. I was surprised.
The vast majority of the features that I’ve come to utilized most in Entourage I’ve been able to duplicate in PowerMail.
So far so good. They have a 30 day trial period. Give it a shot.
