If you don't want to put your data in another silo, this is what mu [1] and notmuch [2] provide. I have been using mu/mu4e for a while and it is absolutely great for quickly finding e-mail, creating virtual search-based mailboxes, etc. Combined with isync and Fastmail's standard-conforming IMAP support, you have a really nice e-mail setup. Of course, it's not for the general public, but this is Hackernews ;) [1] https://www.djcbsoftware.nl/code/mu/ https://www.djcbsoftware.nl/code/mu/ [2] https://notmuchmail.org https://notmuchmail.org
