+TODO items for public-inbox
+
+(Not in any particular order)
+
+* mailmap support (same as git) for remapping expired email addresses
+
+* 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
+
+* Support optional "HTTPS Everywhere" for mapping old HTTP to HTTPS
+ links if (and only if) the user wants to use HTTPS. We may also
+ be able to configure redirects for expired URLs.
+
+ Note: message bodies rendered as HTML themselves must NOT change,
+ the links should point to an anchor tag within the same page,
+ instead; giving the user options.
+
* implement RFC 4685 (Atom message threading)
-* configurable constants (quote folding, index limits)
+
+* configurable constants (index limits, search results)
+
* use tags as date-based skiplists for navigating history
-* improve + document mlmmj integration, currently only at:
- http://bogomips.org/unicorn-public/20140508084301.GA2033%40dcvr.yhbt.net/
+ (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)
