Junk Email

The Nexus email system automatically places messages it thinks are Junk in a separate 'Junk Mail' folder. Messages in this folder are automatically deleted after 90 days. Whilst most messages there will be junk it is advisable to check it from time to time and move anything that is not junk back to your inbox. When you do this it will prompt you with options to trust the sender address more in future thus reducing the chance of messages from that person ending up in junk again.

In addition to the Junk Mail folder the Nexus Microsoft 365 system also has a quarantine feature which places messages it considers even more dangerous elsewhere such that they are not even visible through the normal mail access. For more information see https://help.it.ox.ac.uk/nexus365-email-quarantine . You can check this quarantine area by logging in with your SSO account at https://security.microsoft.com/quarantine

There is no real way to completely stop these e-mails (known as spam). If you simply delete them from your inbox rather than replying to them this often helps. Many companies put the "Reply to xxx to be removed from the list" at the end of their e-mails so they can see which e-mail addresses are valid. The valid ones then get distributed to other companies, etc.

Any mail entering or leaving the department passes through the university's central email scanning system which checks for viruses and adds header tags which indicate whether it thinks the mail is spam or not. You can thus use this as a means to filter likely spam into a separate folder if you wish to do more than the default Nexus Junk Mail system.
