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: <[email protected]>).
-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: <[email protected]>).
-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.
