From 15 june 2023 the university has installed a 'no automatic mail forwarding to external email address' policy. For details, please read UL policy Automatic Forwarding to external email address or read the policy document
The University mail servers have been changed to revoke automatic mail forwarding to addresses outside the leidenuniv.nl domain. This is done to make sure mails with General Data Protection Regulation (GDPR) sensitive data are not automatically forwarded to places where the university does not have a GDPR processing agreement.
None of these measures actually do anything about the confidentiality of your mail; mails are still stored clear text on our email servers or on any other destination server unless you encrypt them.
If you care about privacy or if you handle sensitive information in your email correspondence, we strongly advise you use encrypted emails. This is rather easy to set up following this guide.
Our filtering rule set allows one bit of customization: if the variable INFOMESSAGE is set to yes, you will
receive a mail informing you that a message matching marked as confidential has been received and left in your INBOX so you will know to check there.
