I would suggest an job_submit plugin: http://www.schedmd.com/slurmdocs/job_submit_plugins.html
There is no mechanism to return a string to the user, only an exit code, but adding a few new exit codes would be simple (see slurm/slurm_errno.h and src/common/slurm_errno.c). We have also discussed adding a mechanism to return an arbitrary string to the user, but this is not possible today.
