""> 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.
