But when I run it with dash, it doesn't seem to work right, and spams the

like this:

bin/mailwatcher: 70: bin/mailwatcher: [[: not found
bin/mailwatcher: 77: bin/mailwatcher: [[: not found
dash isn't the same as bash, as it has a limited set of instructions or
commands it can do.
But I too would be interested to know if it is possible to get it to
work in dash, I don't believe it is, but I am happy to be corrected
or proved wrong.
And finally, once its working with either shell, how do I shut it up
totally? Even the above command line launch fails as it outputs to that
shell, a newline for every incoming mail which gradually scrolls any
output that was on-screen, offscreen without leaving a prompt until I
tap the return key to restore it.
Also isn't the command you are running supposed to be as follows ?
bin/mailwatcher 2>&1 > /dev/null &
