There are several possible reasons:

• You have a Central.uh.edu account, but you redirect your mail to an external mail address (Yahoo, Hotmail, etc.). PureMessage services are only utilized for central.uh.edu mailbox destinations.
• You have not received any spam sent to the Quarantine site in the last 24 hours. You will only receive a digest message if you have had mail sent to the Quarantine site within the last 24 hours.
• You have manually configured your mail account to opt out of PureMessage services. To change this option, first connect to VPN using Full-vpn.uh.edu then login to the Quarantine site (https://qsite.uh.edu:28443/) and select Options.
• You have configured a desktop filtering rule that is redirecting the Digest Messages to somewhere other than your Inbox. Verify your filtering rules are configured to meet your current needs.
