When the Spam Experts Filter quarantines the first email for your email account, you will receive the following email:
Dear Sir / Madam,
Your domain yourmaildomain.com is set to auto-activate daily quarantine reporting. From now onwards you'll receive such report. If you wish to disable these reports, please visit https://login.antispamcloud.com/ . If you have not yet logged in please click "retrieve the login link" and specify your email address. You will then be sent a temporary login link where you can edit your password and control your settings for the protection reports as well as accessing your spam quarantine.
Kind regards,
SpamLogin.com
It is at this time that you would visit: https://login.antispamcloud.com and select "Retrieve log-in link". This will allow you to set a password so that you can login to your quarantine folder any time you wish.
You can also disable the daily notices if you prefer not to recieve the daily quarantine notices.
