NAME
     qmail-smtpd - receive mail via SMTP

SYNOPSIS
     qmail-smtpd

DESCRIPTION
     qmail-smtpd  receives  mail  messages  via  the  Simple Mail
     Transfer Protocol (SMTP) and invokes qmail-queue to  deposit
     them  into the outgoing queue.  qmail-smtpd must be supplied
     several environment variables; see tcp-environ(5).

     qmail-smtpd is responsible for counting  hops.   It  rejects
     any message with 100 or more Received or Delivered-To header
     fields.

     qmail-smtpd  supports  ESMTP,  including  the  8BITMIME  and
     PIPELINING options.

TRANSPARENCY
     qmail-smtpd  converts  the  SMTP newline convention into the
     UNIX newline convention by converting CR LF into LF.

     qmail-smtpd accepts messages that contain long lines or non-
     ASCII characters, even though such messages violate the SMTP
     protocol.

CONTROL FILES
     badmailfrom
          Unacceptable envelope  sender  addresses.   qmail-smtpd
          will  reject  every  recipient address for a message if
          the envelope sender address is listed  in  badmailfrom.
          A line in badmailfrom may be of the form @host, meaning
          every address at host.

     localiphost
          Replacement host name for local IP addresses.  Default:
          me,  if  that  is supplied.  qmail-smtpd is responsible
          for recognizing dotted-decimal addresses for  the  cur-
          rent  host.   When  it  sees a recipient address of the
          form  box@[d.d.d.d],  where  d.d.d.d  is  a  local   IP
          address,  it replaces [d.d.d.d] with localiphost.  This
          is done before rcpthosts.

     rcpthosts
          Allowed RCPT domains.  If rcpthosts is supplied, qmail-
          smtpd will reject any envelope recipient address with a
          domain not listed in rcpthosts.

          Exception: If the environment variable  RELAYCLIENT  is
          set, qmail-smtpd will ignore rcpthosts, and will append
          the value of RELAYCLIENT  to  each  incoming  recipient

          address.

          rcpthosts may include wildcards:

             heaven.af.mil
             .heaven.af.mil

          Envelope recipient addresses without @ signs are always
          allowed through.

     smtpgreeting
          SMTP greeting message.  Default: me, if  that  is  sup-
          plied;  otherwise  qmail-smtpd will refuse to run.  The
          first word of smtpgreeting should be the current host's
          name.

     timeoutsmtpd
          Number  of  seconds  qmail-smtpd will wait for each new
          buffer of data from the remote SMTP  client.   Default:
          1200.
