We use email addresses like this to stop emails about your graduation going to spam.
If you recieved an invitation or a confirmation email from email@example.com or something similar, and you are expecting to be invited to graduate this year, or you just registesred for your graduation ceremony, then it was probably sent by our graduation registration system.
We use a product called EasyDus to manage your attendence at the graduation, but we noticed that emails sometimes ended up in the spam folder of our graduands. For technical reasons, it isn't currently possible to send emails from @rsm.nl, so we instead use @rsmgraduation.nl and @rsmgraduations.nl.
If you want to confirm if any email was genuine, you can always email us at firstname.lastname@example.org
