There is a new web interface for the EECS IMAP mail server.
The URL is: https://webmail.eecs.berkeley.edu
This interface has a different look and feel from the old interface. It also allows the user to manage mail filters on the IMAP server. These rules are processed prior to any other rules that are in place, such as the rules on the server that processes SPAM.
Please feel free to try out this interface.
*It is currently in beta*, but will probably be announced as a production service soon.
The old webmail interface will remain at https://imap.eecs.berkeley.edu.
