Well, I have a hack of a little shell script that will restart it
within 60 seconds. Its not efficient, pleasant or anything else, but
it does the job
Call this script postmasterangel.sh (as in guardian angel) and run it
instead of the postmaster. Change the postmaster line in here to be
your postmaster boot configuration options.

This runs under linux. It will probably work under most un*x
flavors. Dont expect anything under doze unless you use cygwin for it.
Yes its nasty, I wrote it to doa job, not to look good
