       rabid - program to test POP server throughput.

       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
       brackets  and have the port address immidiately following.  If you want
       a DNS lookup for every connection (for testing  round-robin  DNS)  then
       immediately 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.

       If  a conversion-filename is specified then the names in this file will
       be taken as a template and expanded to make  the  real  names  (NB  the
       passwords are not expanded).

       See the postal (8) man page for details of the expansion process.

       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
       configured  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
       representative 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

       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 -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.


       Doesn’t actually do SSL or IMAP yet.
