This is the command smtp-source that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
smtp-source - parallelized 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 or IPv6 servers. IPv4
and IPv6 are the default.
Note: this is an unsupported test program. No attempt is made to maintain compatibility
between successive versions.
Arguments:
-4 Connect to the server with IPv4. This option has no effect when Postfix is built
without IPv6 support.
-6 Connect to the server with IPv6. This option is not available when Postfix is built
without IPv6 support.
-A Don't abort when the server sends something other than the expected positive reply
code.
-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>).
-F file
Send the pre-formatted message header and body in the specified file, while
prepending '.' before lines that begin with '.', and while appending CRLF after
each line.
-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).
-M myhostname
Use the specified hostname or [address] in the HELO command and in the default
sender and recipient addresses, instead of the machine hostname.
-N Prepend a non-repeating sequence number to each recipient address. This avoids the
artificial 100% hit rate in the resolve and rewrite client caches and exercises the
trivial-rewrite daemon, better approximating Postfix performance under real-life
work-loads.
-o Old mode: don't send HELO, and don't send message headers.
-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.
-R interval
Wait for a random period of time 0 <= n <= interval between messages. Suspending
one thread does not affect other delivery threads.
-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>).
-T windowsize
Override the default TCP window size. To work around broken TCP window scaling
implementations, specify a value > 0 and < 65536.
-v Make the program more verbose, for debugging purposes.
-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.
