INTRODUCTION

       s/qmail is a secure, encrypting, authenticating, reliable, efficient,
       yet simple IPv4/IPv6 message transfer agent based on qmail and ought to
       be plug-in compatible.  The s/qmail software includes Dan Bernstein's
       fastforward and qmailanalog package in addition with other enhancements
       taken mainly from the Spamcontrol patch.

       The current version of s/qmail depends on the fehQlibs.

       Users who want to control incoming messages should read dot-qmail(5).
       Available commands for the .qmail file include qbiff(1), qreceipt(1),
       forward(1), fastforward(1), bouncesaying(1), and condredirect(1).
       Other helpful commands include maildirmake(1), maildir2mbox(1), and
       maildirwatch(1).

       System administrators who want to control the entire s/qmail system
       should start with qmail-control(5), qmail-mfrules(8), and
       qmail-start(8).  There are three queue-monitoring tools:
       qmail-qread(8), qmail-qstat(8), and qmail-tcpto(8).  qmail-mrtg(8)
       allows to feed the s/qmail logs to MRTG.  Incoming SMTP connections are
       handled by qmail-smtpd(8) and qmail-recipients(8) optionally together
       with qmail-smtpam(8) and qmail-authuser(8) perhaps with
       qmail-vmailusers(8) if virtual mail managers like vpopmail or vmailmgr
       are in use.

       SRS is availalable within s/qmail by means of the additional commands
       srsforward(1) and srsreverse(1).

       s/qmail offers two command-line message-sending interfaces:
       qmail-inject(8) and mailsubj(1).  For background information on
       Internet mail messages, see addresses(5), envelopes(5),
       qmail-header(5), and forgeries(7).

       Miscellaneous documentation includes qmail-limits(7) and
       qmail-pop3d(8).

       Apart from the Internet mail message transport protocols ESMTP/ESMTPS
       s/qmail supports QMTP/QMTPS together with the Pop Office message
       protocols POP3/POP3S depending on the ucspi-ssl package for TLS
       support.

       This documentation describes version 4.1.08 of s/qmail.  See
       https://www.fehcom.de/djbware.html for other s/qmail-related software.
