smtpping — SMTP benchmarking and measurement tool
smtpping [-dqrJ46] [-p port] [-w wait] [-c count] [-P parallel] [-s size] [-f file] [-H hello] [-S sender] recipient [@server]
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: <>). -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.
