Spam Blocking with UBmail (Central Email)

See how the spam quarantine service works to keep your Inbox free of unwanted and unsolicited email messages.

Spam Is Blocked Automatically

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.

Eligibility for the Spam Quarantine Service

All individuals with UBITName@buffalo.edu email addresses who use UBmail (Central Email) automatically have their email filtered through the spam quarantine service.

Reporting Spam Errors

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.

Submit spam errors directly to the vendor (Sophos.com). The vendor uses customers' reports to refine the spam quarantine database.
