(Most of) my current mail is on a IMAP server. On my desktop box I use offlineimap and mutt, which is pretty cool when you have a keyboard, unlimited disk space and broadband. While it's possible to do the same on Z, I'd appreciate a GPE solution. I tried Sylpheed, which is good, but it was even better if it was better customized for use with stylus and small screen.
What I am looking for is a client, that will download *new* mails in imap/INBOX, so I can read them while disconnected. But it's not the best idea (though possible with 1GB MMC card) to store *all* mails on the Z.
GnuPG, gpe-contacts integration, filters would be cool. Any hints?
