NAME
  smtp-gated - transparently block viruses during SMTP connections
SYNOPSIS
  smtp-gated [-f] [ -h | -s | -S | -r | -t | -T | -v | -V ] config_file
DESCRIPTION
  smtp-gated checks SMTP traffic and blocks any viruses found.
  It can also spam-check messages. E-mail containing virus is blocked
  (SMTP-server session is brought down), and a proper message is sent
  to client software. E-mails found to be a SPAM, can also be blocked,
  or just the fact is logged.

  smtp-gated uses netfilter framework to forward connections to destination
  MTA. It's meant to be transparent, so any SMTP-authentication works ok.
  Also pipelining extension is supported.

  Daemonised scanning engines support is integrated, so there is minimal
  performance hit on scanning.
OPTIONS
        -f      run foreground
        -h      command reference
        -s      prepare & show process status (see USR1 in SIGNALS)
        -S      prepare & show process status file name
        -r      reload configuration
        -t      syntax check & dump configuration (except messages)
        -T      syntax check & dump configuration (including messages)
        -v      show version
        -V      show version & compiled-in options
SIGNALS
        HUP     reload configuration
        USR1    dump statistics (see -s in OPTIONS)
RELAYING
  Listening port *MUST* be protected from world-access or proxy will
  act as open-relay. This can be achieved either by setting bind_address
  to internal IP, or by denying listen-port access from outside world
  using iptables.
EXAMPLE CONFIG FILE
  No examples yet.

  smtp-gated.conf(5)
BUGS
  CHUNKING support may be buggy (and probably is). Also I have encountered
  problem with SpamAssassin, but it should be fixed in version >=1.4.11.
