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 PIPE-
     LINING 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
          current  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.
