Two scripts that come with postfix are smtp-sink and smtp-source. Think 
of smtp-sink as a drain, it sends all e-mail sent to it into the bit 
bucket (for testing how fast your postfix setup can send e-mail). 
smtp-source generates e-mail, for testing the speed/efficiency of mail 
that would be incoming to your postfix setup. smtp-source is the tool 
you probably want to use, although it will load postfix down more than 
cyrus it may still be valuable for testing cyrus limitations.
