smtp-source8

Usage

Overview

smtp-source connects to the named host and port (default 25) and sends one or more little messages to it, either sequentially or in parallel.

Options:

-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.

-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. The default is one recipient per transaction.

-s session_count

Run the specified number of SMTP sessions in parallel (default: 1).

-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.
