[slurm-users] Filter slurm e-mail notification

[Brian Andrus]

I guess you need to decide how to approach it.

If you can't educate users as to how to appropriately use the -mail 
flag, then you are assuming they will abuse it.
In that situation, you need to configure your mail server itself to rate 
limit or something. That approach depends on the mail server you use.

The best solution, of course, is to educate the users.
You could create a job_submit plugin that removes mail options for 
arrays, but you may negatively impact users that do need that.

Valid type values are NONE, BEGIN, END, FAIL, REQUEUE, ALL (equivalent to BEGIN, END, FAIL, REQUEUE, and STAGE_OUT), STAGE_OUT (burst buffer stage out and teardown completed), TIME_LIMIT, TIME_LIMIT_90 (reached 90 percent of time limit), TIME_LIMIT_80 (reached 80 percent of time limit), TIME_LIMIT_50 (reached 50 percent of time limit) and ARRAY_TASKS (send emails for each array task). Multiple type values may be specified in a comma separated list. The user to be notified is indicated with --mail-user. Unless the ARRAY_TASKS option is specified, mail notifications on job BEGIN, END and FAIL apply to a job array as a whole rather than generating individual email messages for each task in the job array.
