Most HPC batch systems can be configured to send users an email when their job starts and stops. This is usually achieved by adding a specific line to the job submission script including the user's email address.
At present, SimFactory includes this line in all job submission scripts. This means that the user cannot choose whether to receive these emails or not.
I propose a new machine-specific option which allows the user to enable or disable all job-related emails. This could be an entry in the machine database which was by default unset, could be specified in the [default] machine, or customised on a per-machine basis. For example, I probably don't want job notification emails for my laptop, but for Kraken where jobs can take a long time to start I probably do.
