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 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.
BUGS
No SMTP command pipelining support.
