Sad, I know, but my earliest emails are from 1993. I think I received them using zmail on an old SGI box and as they contain useful technical info I have never deleted them. They are still fully compatible with my mail apps on various *nix platforms I have round the house. Why do people need to upgrade mail clients anyway? Except for security reasons.

At work I use Notes and Outlook - hate them both, but Notes wins hands down for stability and user-friendliness. When I have to use Outlook I disable everything I can, and force it to only receive plain text.
