Perdition (Email Proxy) Retirement

This article explains support for retirement of the Perdition portion of the University of Chicago email system. It provides recommendations for clients using the perdition imap/pop proxy server.

What is Perdition?

Perdition is a POP and IMAP proxy server. Email programs connecting to or actually hit Perdition first. Perdition allows authentication by email alias (rather than using the standard CNetID and password) that a very few remaining people might be using to access their xMail account.

What is happening to Perdition?

The Perdition server will be retired in anticipation of later more substantial changes to the University of Chicago email system.

What changes will be required of those using Perdition?

Because the functionality of authentication by email alias will not be replaced when Perdition is retired, it will be necessary to reconfigure email programs to use the standard CNetID and password. We have documentation regarding how to configure email clients to authenticate using standard CNetID and password rather than an email alias. We are also ready to assist over the phone (773.702.5800) or email ( or in-person at our Regenstein TechBar.
