NAME

4     smtpping — SMTP benchmarking and measurement tool

SYNOPSIS

7     smtpping [-dqrJ46C] [-p port] [-w wait] [-c count] [-P parallel]
8              [-s size] [-f file] [-H hello] [-S sender] recipient [@server]

DESCRIPTION

11     smtpping is a small tool that performs SMTP server delay, delay variation
12     and throughput measurements.
13
14     It must be invoked with the recipient email address. Normally, the server
15     should also be specified (prefixed with @); otherwise smtpping will try
16     to find the recipient domain's MX record, falling back on A/AAAA records.
17
18     The following options are available:
19
20     -4      Use IPv4.
21
22     -6      Use IPv6.
23
24     -p port
25             Specifies the TCP port to use (default: 25).
26
27     -w wait
28             Time in milliseconds to wait between pings (default: 1000).
29
30     -c count
31             Number of pings to send (default: unlimited).
32
33     -P processes
34             Number of parallel worker processes (default: 1). To measure
35             throughput, it's recommended to use -r and -w0 with this option.
36
37     -s size
38             Ping message size in kilobytes (default: 10). Cannot be used in
39             conjunction with the -f option.
40
41     -f file
42             Send the specified email file (message/rfc822) instead of a gen‐
43             erated message. Cannot be used in conjunction with the -s option.
44
45     -H helo
46             HELO name (default: localhost.localdomain).
47
48     -S sender
49             Sender address (default: <>).
50
51     -C      Use CHUNKING (BDAT)
52
53     -r      Display rate instead of transaction delays. To measure through‐
54             put, it's recommended to use -w0 and possibly -P with this op‐
55             tion.
56
57     -q      Display less verbose output.
58
59     -d      Display more verbose output.
