19 (default: port
25) and sends one or more messages to it,
20 either sequentially or in parallel. The program speaks
21 either SMTP (default) or LMTP. Connections can be made to
22 UNIX-domain and IPv4 or IPv6 servers. IPv4 and IPv6 are

38 <b>-A
</b> Don't abort when the server sends something other
39 than the expected positive reply code.
41 <b>-c
</b> Display a running counter that is incremented each
42 time an SMTP DATA command completes.
44 <b>-C
</b> <i>count
</i>
45 When a host sends RESET instead of SYN|ACK, try
46 <i>count
</i> times before giving up. The default count is
47 1. Specify a larger count in order to work around a
48 problem with TCP/IP stacks that send RESET when the

</b> Don't disconnect after sending a message; send the
52 next message over the same connection.
55 Use the specified sender address (default:
56 <foo@
<a href=
"postconf.5.html#myhostname">myhostname
</a>>).
59 Send the pre-formatted message header and body in
60 the specified
<i>file
</i>, while prepending '.' before
61 lines that begin with '.', and while appending CRLF
64 <b>-l
</b> <i>length
</i>
65 Send

66 does not include message headers.
68 <b>-L
</b> Speak LMTP rather than SMTP.

</i>
71 Send the specified number of messages (default:
1).
73 <b>-M
</b> <i><a href=
"postconf.5.html#myhostname">myhostname
</a></i>
74 Use the specified hostname or [address] in the HELO
75 command and in the default sender and recipient
76 addresses, instead of the machine hostname.
78 <b>-N
</b> Prepend a non-repeating sequence number to each
79 recipient address. This avoids the artificial
100%
80 hit rate in the resolve and rewrite client caches
81 and exercises the trivial-rewrite daemon, better
82 approximating Postfix performance under real-life
85 <b>-o
</b> Old mode: don't send HELO, and don't send message
88 <b>-r

89 Send the specified number of recipients per trans-
90 action (default:
1). Recipient names are generated
91 by prepending a number to the recipient address.
93 <b>-R
</b> <i>interval
</i>
94 Wait for a random period of time
0 <= n

95 between messages. Suspending one thread does not
96 affect other delivery threads.

110 Override the default TCP window size. To work
111 around broken TCP window scaling implementations,
112 specify a value
