NAME
smtpping — SMTP benchmarking and measurement tool
SYNOPSIS
smtpping [ -dqrJ46C ] [ -p port ] [ -w wait ] [ -c count ] [ -P parallel ] [ -s size ] [ -f file ] [ -H hello ] [ -S sender ] recipient [ @server ]
DESCRIPTION
smtpping is a small tool that performs SMTP server delay, delay variation and throughput measurements.
It must be invoked with the recipient email address. Normally, the server should also be specified (prefixed with @); otherwise smtpping will try to find the recipient domain’s MX record, falling back on A/AAAA records.
The following options are available:
-4
Use IPv4.
-6
Use IPv6.
-p port
Specifies the TCP port to use (default: 25).
-w wait
Time in milliseconds to wait between pings (default: 1000).
-c count
Number of pings to send (default: unlimited).
-P processes
Number of parallel worker processes (default: 1). To measure throughput, it’s recommended to use -r and -w0 with this option.
-s size
Ping message size in kilobytes (default: 10). Cannot be used in conjunction with the -f option.
-f file
Send the specified email file (message/rfc822) instead of a generated message. Cannot be used in conjunction with the -s option.
-H helo
HELO name (default: localhost.localdomain).
-S sender
Sender address (default: <>).
-C
Use CHUNKING (BDAT)
-r
Display rate instead of transaction delays. To measure throughput, it’s recommended to use -w0 and possibly -P with this option.
-q
Display less verbose output.
-d
Display more verbose output.
