     "Nullmailer is a simple replacement @acronym{MTA, Mail Transfer Agent} for
hosts that receive no local mail and only relay mail to a fixed set of smart
relays.  It's useful for systems such as Web servers that must be able to send
email notifications, without having to run a full-blown MTA such as sendmail
or qmail.

Nullmailer is designed to be simple to configure, easy to extend, and secure.
It requires little ongoing administration.  The included @command{sendmail}
emulator front-end should allow most (if not all) sendmail-compatible programs
to run without any changes.")

KPOP, all flavors of IMAP, ETRN, and ODMR.  It can even support IPv6
and IPSEC.

Fetchmail retrieves mail from remote mail servers and forwards it via SMTP,
so it can then be read by normal mail user agents such as mutt, elm
or BSD Mail.  It allows all your system MTA's filtering, forwarding, and
aliasing facilities to work just as they would on normal mail.")

       "Pigeonhole adds support for the Sieve language (RFC 5228) and the
ManageSieve protocol (RFC 5804) to the Dovecot e-mail server.

@dfn{Sieve} is a language for filtering incoming mail.  Messages can be
forwarded or sorted into separate folders.  Unwanted messages can be rejected
or discarded, and, when the user is not available, the Sieve interpreter can
send an automated reply.

Sieve is meant to be simple, extensible, and system-independent.  The
intention is to make it impossible to write anything more complex (and
dangerous) than simple mail filters.  Unlike most other mail filtering script
languages, Sieve does not allow users to execute arbitrary programmes.

Through the @dfn{ManageSieve} protocol, users can remotely manage their Sieve
scripts without needing file system access.  The server accepts only valid
scripts to prevent embarrassing errors later on.")

     "Technology for Resting Email Encrypted Storage (TREES) is a NaCL-based
Dovecot encryption plugin.  This plugin adds individually encrypted mail
storage to the Dovecot IMAP server.  It is inspired by Posteo's scrambler
which uses OpenSSL and RSA key pairs.  TREES works in a similar way, but uses
the Sodium crypto library (based on NaCL).

How it works:
@enumerate
@item On IMAP log in, the user's cleartext password is passed to the plugin.
@item The plugin creates an argon2 digest from the password.
@item This password digest is used as a symmetric secret to decrypt a libsodium secretbox.
@item Inside the secretbox is stored a Curve25519 private key.
@item The Curve25519 private key is used to decrypt each individual message,
using libsodium sealed boxes.
@item New mail is encrypted as it arrives using the Curve25519 public key.
@end enumerate\n")

    (synopsis "Unix utilities to deal with Maildir")
    (description
     "The mblaze message system is a set of Unix utilities for processing and
interacting with mail messages which are stored in maildir folders.

Its design is roughly inspired by MH, the RAND Message Handling System, but it
is a complete implementation from scratch.

mblaze is a classic command line MUA and has no features for receiving or
transferring messages; you can operate on messages in a local maildir spool,
or fetch your messages using fdm(1), getmail(1), offlineimap(1), or similar
utilities, and send it using dma(8), msmtp(1), sendmail(8), as provided by
OpenSMTPD, Postfix, or similar.

mblaze operates directly on maildir folders and doesn't use its own caches or
databases.  There is no setup needed for many uses.  All utilities have been
written with performance in mind.  Enumeration of all messages in a maildir is
avoided unless necessary, and then optimized to limit syscalls.  Parsing
message metadata is optimized to limit I/O requests.  Initial operations on a
large maildir may feel slow, but as soon as they are in the file system cache,
everything is blazingly fast.  The utilities are written to be memory

@dfn{Sieve} (RFC 5228) is a specialised language for e-mail filtering.  Sieve
scripts are stored on the server and run whenever mail arrives.  They can
automatically sort new messages into folders, silently reject them, send an
automated response, and more.

@command{sieve-connect} is designed to be both a tool which can be invoked
from scripts as well as a decent interactive client.  It supports TLS for
connection privacy, as well as authentication with SASL or GSSAPI client
certificates.  It should be a drop-in replacement for @command{sieveshell}
