mail to username not working

[PatrickPaul-NRC]

Email to the username should be sent to the email address known to centrify.

As an intermediate fix, you should be able to add a flag in slurm with an email address as part of the job submission script

I know how to work around that but this should just work.

Mail alias maps are not present in the domain. Instead the User Principal is set to the local domain which cannot receive email directly. Setting up a mapping by default requires populating the mail aliases in /etc/aliases and a postalias hash:/etc/aliases; postfix reload or per-user in the $HOME local forward path.

A script was written to attempt to form the alias mappings by querying users from the domain. The issue is that in some cases it is best effort and would require to be constantly refreshed into /etc/aliases file and distributed to nodes.

Therefore, it is suggested the best practice on the cluster instead, is to make use of the SLURM directives and specify a full email address for the recipient as suggested above.

That being stated an attempt at making mail forwarding work on trixie-hn1 to NRC addresses has been performed. If it shows to work as expected, the aliases can be distributed to the compute nodes, so the defaults work as expected.
