NAME¶
bhm - program to send SMTP mail to /dev/null
SYNOPSIS¶
bhm [-m maximum-message-size] [-t threads] [-p listen-port] [ -s ]
[-a] [-[z|Z] debug-file] [-r reverse-dns] user-list-filename
DESCRIPTION¶
This manual page documents briefly the
bhm, program.
It is designed to test the performance of SMTP relay servers by receiving mail
to /dev/null at random speeds.
The
user-list-filename is the name of a file which contains a list of
valid user's email addresses. The file may have three fields separated by
spaces, the email address, the password (used for rabid) and an optional third
field to specify what is to be done with the mail. A 'd' character means that
it is to be deferred (SMTP 45x), a 'r' means that it is to be rejected (SMTP
55x), a 'b' means that it is to be accepted and bounced, and a 'g' means that
it is to be grey-listed.
The
reverse-dns file is in the same format as /etc/hosts and gives the
value that will be used in the 220 message. Otherwise it will be
bhm
The
maximum-message-size indicates the size in Kilobytes that will be the
maximum size of a message that will be accepted. The default is 10240k.
The
-s parameter enables SSL.
The
listen-port parameter specifies the TCP port to listen on (default
25).
The
threads parameter is the number of threads that may be created to
receive mail. Note that your BHM machine may have hardware and OS limits that
determine how many connections it may receive.
The
-a command turns on all logging. All message data received will be
logged. This will make it slow and it may not be able to saturate a fast
Ethernet link...
The
-z switch allows you to specify a debugging file base. From this base
one file is created for each thread (with a ':' and the thread number
appended), each file is used to log all IO performed by that thread for
debugging purposes.
The
-Z switch is the same but creates a separate file for each connection
as well with an attitional ':' appended followed by the connection number.
