Thanks DKRR, can I add tips for *nix? (I apologises DKRR I think.. off the topic from telnet,if you don't like it I'll erase ASAP), I've got "grepmail" installed on my *nix box. This is how I search my mail folder using "grepmail":
1. Let's say I wanna see a mail folder and have name "Toshiba Shop"
% grepmail -R -i -l toshiba ~/Mail
Mail/conf/acs_w01
2. Last week I was looking for the "phone number" of "Toshiba Shop", which was in a mail message somewhere, but I couldn't remember where I'd filed it. So I done this one:
% grepmail -i toshiba '!!' | grep -i telephone
Telephone: 365-652-654
