.Nm
.Op Fl dqrJ46
.Op Fl p Ar port
.Op Fl w Ar wait
.Op Fl c Ar count
.Op Fl P Ar parallel
.Op Fl s Ar size
.Op Fl f Ar file
.Op Fl H Ar hello

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