You can login to your quarantine area at any time, despite whether you've received a quarantine report or not.
Once the server recognizes your email address, you will be sent an email automatically with the subject line:
User Quarantine Account Information
This email will contain a username (which will be your email address) and a system generated password that you will use to login to the web based quarantine and preferences area when not linking directly from a quarantine email.
To login to your quarantine and preferences area go to http://inbox.machighway.com/ , enter your email address and then click "Create New Password".
