UBmail (Central Email) uses PureMessage, a spam quarantine service which examines incoming email messages using extensive rules to determine the likelihood that each message is spam.

Each incoming or outgoing message is assigned a numeric spam score in the message header. Email messages with high spam scores are quarantined or discarded.

Quarantined Spam

• Incoming email messages that are 50% - 98% likely to be spam are held in your Blocked Messages folder for 28 days before the spam quarantine service automatically deletes them.
• Quarantined spam is not delivered to your mailbox, so it does not count toward your quota.

Discarded Spam

• Incoming email messages that are 99% - 100% likely to be spam are automatically deleted.
• Outgoing email messages (either generated at UB or forwarded through UB) that are 80% - 99% likely to be spam are automatically deleted before reaching their destinations.

Spam errors include:

• False positives: legitimate email messages that are quarantined because they have been mistakenly marked as spam.
• Undetected spam: email messages that the spam quarantine service failed to recognize as spam and failed to quarantine or discard.
