The Bat! email client from Ritlabs has been around for years – 1998 to be precise – and is widely accepted as one of the best secure packages available. I was a registered user back when V4 was roaming the land, but for whatever reason gave up and pursued other avenues. I felt it was time to revisit.
The Bat! interface has not changed one iota over the years, but extra buttons have been created as functionality has increased and, if I am honest, it is not the most user-friendly front end. In fact, configuring The Bat! is, how can I put this nicely, a complete bastard!
