Laptop uses Mail.app, Linux system is using Thunderbird, Outlook is used
on the Windows system. I would be willing to try out Balsa or KMail if
they have good IMAP support and support for decent filtering rules...I
just had the impression that Thunderbird was actively developed and
The main problem I saw was making sure I had a key on all three systems
that was sync'd up. Lose the key, lose the email. Ideally I could use
a system that would use an algorithm each could use (like Blowfish) and
would base it on a password that is prompted, like interactive SSH
sessions. That way I could encrypt the messages using a password at
either the startup of the mail client or when encrypting the message,
and the end recipient would also have a password to decrypt it.
