One of the systems that will be upgraded during our upcoming maintenance window on Friday night is our Barracuda spam filters. After this update, you will no longer be able to access your account by clicking on a link in the quarantine summary email.

Example:

Starting Saturday, when you click on a link in the quarantine summary email, you will be prompted to log in to your account. Your username will be your full email address. Your password may or may not be the same as the password for your email account. If you do not know your password, you can click on the ?Create New Password? button and have a new password emailed to you.
