# emailrelay-test.sh
#
# Tests the E-MailRelay system.
#
# Creates four temporary spool directories under /tmp and runs
# four emailrelay servers to bucket-brigade a test message from one to 
# the next. The test succeeds if the message gets into the final 
# spool directory.
#
# Once all the servers have been killed the separate log files are 
# concatenated into the summary log file "/tmp/emailrelay-test.out".
#
# If this test takes more than a second or two then it has failed.
