TODO items for public-inbox (Not in any particular order) * mailmap support (same as git) for remapping expired email addresses * Optional cookies in WWW interface for user-configurable colors * WWW: Hybrid flat view + thread skeleton (requires Xapian) * POP3 server, since some webmail providers support external POP3: https://public-inbox.org/meta/20160411034104.GA7817@dcvr.yhbt.net/ * TLS support for various daemons (including STARTTLS for NNTP and POP3) * Unix socket support for HTTP and POP3 server for use behind reverse proxies like nginx * Combined "super server" for NNTP/HTTP/POP3 to reduce memory overhead * Optional reply-to-list support for mirroring lists that want it :< Reply-to-list encourages the existing list as a single-point-of-failure, but having an extra mirror using public-inbox.org is nice regardless. * Configurable linkification for per-inbox shorthands: "$gmane/123456" could be configured to expand to the appropriate link pointing to the gmane.org list archives, likewise "[Bug #123456]" could be configured to expand to point to some project's bug tracker at http://example.com/bug/123456 * implement RFC 4685 (Atom message threading) * configurable constants (index limits, search results) * use tags as date-based skiplists for navigating history (maybe not needed with Xapian support nowadays?) * handle Xapian date range queries: http://mid.gmane.org/20151005222157.GE5880@survex.com * use REQUEST_URI properly for CGI / mod_perl2 compatibility with Message-IDs which include '%' (done?) * more test cases (use git fast-import to speed up creation) * large mbox/Maildir/MH/NNTP spool import (use git fast-import) * improve + document mlmmj integration, currently only at: http://bogomips.org/unicorn-public/20140508084301.GA2033%40dcvr.yhbt.net/
