I'm looking for a [gui] mail client that (doesn't suck):

1) Allows me to use any smtp server (with authorization) 2) Supports pop3 at least. imap4 is optional 3) Works in ``offline mode''. That is, when I'm offline, it should queue the mails and only attempt to contact the smtp server when I go online (as in outlook). Should not depend on /usr/lib/sendmail in any way. 4) Supports mail filtering and sorting, pref. with the help of procmail. i.e. it should use procmail if I ask it to. 5) Stores mail in mbox format. 6) Supports search through messages by regex. 7) Let's me use Vim as editor for composing mails.

I can add more to the list, but this much will do. Pine doesn't have 1 (auth), 2, 3, 4, 6. Mutt, AFAIK, doesn't have 1, 4. Most GUI clients don't have 6 and 7. Outlook doesn't have 5, 6, 7 (and 4, if you don't like the message rules in outlook).

I've been living with sendmail+fetchmail+procmail+pine+vim all this while but I want something easier now. I want to get rid of sendmail in that equation. I'd like something like Outlook plus a portable file format, regex searches, procmail-like rules, and the ``Let Me Use VIM'' feature.

Suggestions?
