NAME

smtpping – SMTP benchmarking and measurement tool

SYNOPSIS

[-dqrJ46 ] [-p port ] [-w wait ] [-c count ] [-P parallell ] [-s size ] [-f file ] [-H hello ] [-S sender ] recipient [@server ]

DESCRIPTION

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 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 parallell 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.
