       public-inbox-pop3d - POP3 server for sharing public-inboxes

         public-inbox-pop3d [OPTIONS]

       public-inbox-pop3d provides a POP3 daemon for public-inbox.  It uses
       options and environment variables common to all read-only
       public-inbox-daemon(8) implementations, but requires additional read-
       write storage to keep track of deleted messages on a per-user basis.

       Like public-inbox-imapd(1), "public-inbox-pop3d" will never require
       write access to the directory where the public-inboxes are stored.

       It is designed for anonymous access, thus the password is always
       "anonymous" (all lower-case).

       Usernames are of the format:


       Where $UUID is the output of the uuidgen(1) command.  Dash ("-")
       characters in UUIDs are ignored, and "[A-F]" hex characters are case-
       insensitive.  Users should keep their UUIDs private to prevent others
       from deleting unretrieved messages.  Users may switch to a new UUID at
       any time to retrieve previously-retrieved messages.

       Historical slices of 50K messages are available by suffixing the
       integer $SLICE, where 0 is the oldest.


       It may be run as a different user than the user running
       public-inbox-watch(1), public-inbox-mda(1), or public-inbox-fetch(1).

       To save storage, "publicinbox.pop3state" only stores the highest-
       numbered deleted message

       See common options in "OPTIONS" in public-inbox-daemon(8).

       -l PROTOCOL://ADDRESS/?cert=/path/to/cert,key=/path/to/key
       --listen PROTOCOL://ADDRESS/?cert=/path/to/cert,key=/path/to/key
           In addition to the normal "-l"/"--listen" switch described in
           public-inbox-daemon(8), the "PROTOCOL" prefix (e.g. "pop3://" or
           "pop3s://") may be specified to force a given protocol.

           For STARTTLS and POP3S support, the "cert" and "key" may be
           specified on a per-listener basis after a "?" character and
           separated by ",".  These directives are per-directive, and it's
           possible to use a different cert for every listener.

       --cert /path/to/cert
           The default TLS certificate for optional STARTTLS and POP3S support
           if the "cert" option is not given with "--listen".

           If using systemd-compatible socket activation and a TCP listener on
           port 995 is inherited, it is automatically POP3S when this option
           is given.  When a listener on port 110 is inherited and this option
           is given, it automatically gets STARTTLS support.

       --key /path/to/key
           The default private TLS certificate key for optional STARTTLS and
           POP3S support if the "key" option is not given with "--listen".
           The private key may be concatenated into the path used by "--cert",
           in which case this option is not needed.

       Aside from "publicinbox.pop3state", "public-inbox-pop3d" uses the same
       configuration knobs as public-inbox-nntpd(1), see public-inbox-nntpd(1)
       and public-inbox-config(5).

               A directory containing per-user/mailbox account information;
               must be writable to the "public-inbox-pop3d" process.

               The newsgroup name maps to a POP3 folder name.
