Anti-Spam Filter
How does the Anti-Spam Filter Work?
The anti-spam filter systems “quarantine” suspected spam by examining the headers and content of messages for known spamming addresses and/or spamming content.
The systems also use RBLs (blacklists) and spam filter files, which are updated frequently to include the latest known spam formats.
The quarantine process routes suspected spam messages to a holding location. You receive an email report twice daily, identifying the number and type of messages that were quarantined. You will receive an email report only if email is quarantined for your address in the most recent interval.
Occasionally, legitimate email is marked as spam. Make sure you check your reports for legitimate email.
Quarantined messages are held for 14 days, and then are permanently removed from our system.
