Container exits after a while

[NicolasLM]

First thank you for crafting this image. We've been using it for a while without problems until recently, when it started to stop itself quite quickly:

$ docker run -ti --rm -p 783:783 dinkel/spamassassin

Maybe the run.sh tries to do too much. The problem is solved by replacing it by:

#!/bin/bash
set -m

./rule-update.sh &
exec ./spamd.sh

Of course with this approach the container will still run even if the update fails.
