       rabid - program to test POP server throughput.

       rabid [-r max-connections-per-minute] [-p processes] [-l	local-address]
       [-c messages-per-connection] [-a] [-s ssl-percentage] [-i imap-percent-
       age]   [-b   qmail-pop]	 [-d  download-percentage[:delete-percentage]]
       [-[z|Z] debug-file] [-u]	pop-server user-list-filename

       This manual page	documents briefly the rabid, program.

       It is designed to test the performance of POP email servers by  reading
       all  messages  from  randomly selected accounts as fast as possible.  A
       future version will support rate	limiting to provide  a	constant  load
       (for testing SMTP servers).

       The  pop-server	parameter specifies the	IP address or name of the mail
       server that the mail is to downloaded from.  If you want	to  specify  a
       port other than port 110	then enclose the host address in square	brack-
       ets and have the	port address immidiately following.  If	you want a DNS
       lookup  for every connection (for testing round-robin DNS) then immedi-
       ately preceed the host address with a '+' character.

       The user-list-filename is the name of a file which contains a  list  of
       user's  email  addresses	 and  passwords.  It will have one address per
       line and	the password follows the address with a	space to seperate.

       The processes parameter is the  number  of  processes  that  should  be
       forked  off  to	attempt	 seperate connections.	A well configured mail
       server won't accept an unlimited	number of connections so make sure you
       don't  specify a	number larger than the number your mail	server is con-
       figured to handle.  Also	for sensible results make sure that you	 don't
       use enough to make your server thrash as	the results won't be represen-
       tative of real-world use.

       The max-connections-per-minute parameter	is for limiting	the number  of
       connections  that  the program makes.  This is designed to be used when
       you want	to test	the performance	of other programs when the  system  is
       under load.  The	default	is 24000 connections per minute.

       The  messages-per-connection  parameter specifies the maximum number of
       messages	to download in a single	POP session.  The default is  -1  (un-

       The  local-address  parameter  specifies	which local IP address(es) are
       used to make the	outbound connections.  Specified in the	 same  way  as
       the  remote  address.  This is good for testing LocalDirectors or other
       devices that perform differently	depending on which source  IP  address
       was used.

       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  -s switch specifies	the percentage of connections which are	to use
       TLS AKA SSL.  Use 0 for no SSL, or 100 for always SSL, or any number in
       between.	 Default is 0.

       The  -i switch specifies	the percentage of IMAP connections (default is

       The -b switch allows you	to specify breakage  strings.	Currently  the
       only  option  is	for Qmail POP server which adds	an extra blank line at
       the end of each message.	 -b qmail-pop means to not report this	as  an

       -d  download-percentage[:delete-percentage]  allows you to specify what
       percentage of the messages are downloaded and what  percentage  of  the
       downloaded messages are deleted.	 Default is 100%.

       The  -u switch causes the domain	of user-names to be ignored.  This al-
       lows you	to have	a single file with user-names and passwords which  can
       be  used	by postal and rabid when using a server	which doesn't accept a
       domain.	By default postal will ignore the password field, rabid	may or
       may  not	 need  the  domain  depending  on the configuration of the POP
       server.	The default is to use the domain (which	 is  required  if  the
       same  user  is present in multiple domains), this switch	causes the do-
       main part to be stripped	from the user-name field.

       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 connec-
       tion as well with an attitional ':' appended followed by	the connection

       Doesn't actually	do SSL or IMAP yet.
