SMTP-SOURCE(1) General Commands Manual SMTP-SOURCE(1)
smtp-source - multi-threaded SMTP/LMTP test generator
smtp-source [options] [inet:]host[:port]
smtp-source [options] unix:pathname
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 paral-

be made to UNIX-domain and IPV4 servers. IPV4 is the default.
-c Display a running counter that is incremented each time an SMTP
DATA command completes.
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.
Use the specified sender address (default: <foo@myhostname>).
-o Old mode: don't send HELO, and don't send message headers.
Send length bytes as message payload. The length does not
include message headers.
-L Speak LMTP rather than SMTP.
Send the specified number of messages (default: 1).

Send mail with the named subject line (default: none).
-t to Use the specified recipient address (default: <foo@myhostname>).
Wait for a random period of time 0 <= n <= interval between mes-
