SMTP-SOURCE

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 transaction (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 parallel (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.
