What is the Math email relay system?
The Math email relay system is used to relay, or forward, email to an individual’s email inbox. More specifically, the Math email relay system forwards mail addressed to @math.uiuc.edu or @math.illinois.edu to actual email accounts, such as @illinois.edu address.
The Math email relay is equivalent to giving the post office a forwarding address. When mail is sent the post office has instructions to forward that mail. The Math email relay is merely the instructions to forward mail.
Why is the Math email relay system being decommissioned?
The Math email relay system is running an operating system (OS) that is beyond the server’s end of life. The OS can no longer be updated and security flaws cannot be patched. Further, we are no longer able to modify or update the settings on the email relay server because of the antiquated server OS and setup.
Additionally, the University has updated IT policies to restrict auto-forwarding email due to cybersecurity risks.
Who will be affected by this decommissioning?
This decommissioning will affect anyone currently using @math.uiuc.edu or @math.illinois.edu addresses to receive email of any kind.
What will happen when the email relay is decommissioned?
All email messages sent to email address @math.uiuc.edu or @math.illinois.edu will fail. If someone emails you at one of these addresses, or you try to recover a password to an online account that uses one of these addresses, you will never receive the message.
Senders may or may not get an error message if they send mail to a decommissioned address. Further, their email clients may begin to block or ignore messages from you if they receive a certain number of bounce back emails when sending to you. Do not rely on people receiving a bounce back and then finding the correct email address.
