       bhm - program to send SMTP mail to /dev/null


       bhm  [-m maximum-message-size] [-t threads] [-b bind-address] [-p listen-port] [ -s ] [-a]
       [-[z|Z] debug-file] [-r reverse-dns] user-list-filename


       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 bind-address parameter specifies the IP address to bind to (default  is  INADDR_ANY  -
       accept connections on all local addresses).

       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.
