Still can't figure out why you ignore Pegasus Mail. Not only will it
completely disable embedded scripts in e-mails by default and support
plugins which automatically invoke the virus scanner of your choice
whenever an attachment is saved, opened or viewed but will also allow
you to colourize – if that turns you on – as well as a host of other
things! Free, no ads, and SAFE! And one of the most user-configurable applications I've ever seen.

No way. The Pegasus UI has always ben pegasucky. Even back when Microsoft Internet Mail and News wasn't even on the drawing table, Pega still sucked. Sorry, but if a program looks like ass, I refuse to use it for longer than twenty seconds. I'll stick with Pine when other e-mail clients are ruled out.
