SMTP-SOURCE(1)                                     SMTP-SOURCE(1)

NAME
       smtp-source - multi-threaded SMTP/LMTP test generator

SYNOPSIS
       smtp-source [options] [inet:]host[:port]

       smtp-source [options] unix:pathname

DESCRIPTION
       smtp-source  connects  to  the  named  host  and  TCP port
       (default: port 25) and sends one or more messages  to  it,
       either  sequentially  or  in  parallel. The program speaks
       either SMTP (default) or LMTP. Connections can be made  to
       UNIX-domain and IPV4 servers.  IPV4 is the default.

       Arguments:

       -c     Display  a running counter that is incremented each
              time an SMTP DATA command completes.

       -C count
              When a host sends RESET  instead  of  SYN|ACK,  try
              count  times before giving up. The default count is
              1. Specify a larger count in order to work around a
              problem with TCP/IP stacks that send RESET when the
              listen queue is full.

       -d     Don't disconnect after sending a message; send  the
              next message over the same connection.

       -f from
              Use   the   specified   sender   address  (default:
              <foo@myhostname>).

       -o     Old mode: don't send HELO, and don't  send  message
              headers.

       -l length
              Send  length  bytes  as message payload. The length
              does not include message headers.

       -L     Speak LMTP rather than SMTP.

       -m message_count
              Send the specified number of messages (default: 1).

       -r recipient_count
              Send  the specified number of recipients per trans-
              action (default: 1).  Recipient names are generated
              by prepending a number to the recipient address.

       -s session_count
              Run the specified number of SMTP sessions in paral-
              lel (default: 1).

       -S subject
              Send mail with the  named  subject  line  (default:
              none).

       -t to  Use   the  specified  recipient  address  (default:
              <foo@myhostname>).

       -R interval
              Wait for a random period of time 0 <= n <= interval
              between  messages.   Suspending one thread does not
              affect other delivery threads.

       -w interval
              Wait a fixed time between messages.  Suspending one
              thread does not affect other delivery threads.

       [inet:]host[:port]
              Connect  via  TCP  to  host  host,  port  port. The
              default port is smtp.

       unix:pathname
              Connect to the UNIX-domain socket at pathname.

BUGS
       No SMTP command pipelining support.
