Spam Firewall


WesternU’s spam firewall uses a variety of technologies to detect and filter spam. It provides services for all accounts. The spam firewall can take one of four actions for each message it processes:

  • Allow – The message is delivered to your inbox because the message is not detected as spam or the sender is on your whitelist.
  • Tag – The message is delivered to your inbox with the subject pre-pended with “[BULK]”. This message could be spam based on the content.
  • Quarantine -The message is quarantined on the spam firewall and not delivered to your inbox. These messages are likely spam. You can review your quarantine and release any messages that are not spam to your inbox.
  • Block – The message is from a known spam source, has known spam or scam patterns, or contained a virus. The message discarded with no notification to the sender or receiver.


You can learn more about the functions and settings of the spam firewall by going to the Spam Firewall User’s Guide (68K pdf file). Or you can see if your questions are among those answered below.

  • Internal e-mail from Western University is not filtered by the spam firewall and will not be affected by any blacklist or whitelist entries.


Why do I sometimes get an e-mail that is obviously spam?

Spammers are constantly changing their techniques to get around spam filters. It is almost impossible to predict what techniques spammers will employ next. In addition, different spammers use different techniques. The spam firewall is constantly learning new spammer techniques to keep up to date.


I received two spam e-mails that were the same. One message showed up in my Inbox and the other showed up in my quarantine. How is this possible?

Although the messages looked the same to you, the message could have appeared different to the spam firewall. Many spammers send out thousands of messages from different sources that look the same but are slightly different in hopes that a few will get through spam firewalls.


I keep getting the exact same type of spam. Can I submit it for review?

Yes. Please send your messages to the Helpdesk. Please include the headers of the message if possible.


An acquaintance of mine is sending me a file but I never receive it. What could be the problem?

There are two possibilities caused by the spam firewall.
  1. The file could contain a virus. The spam firewall discards any e-mail that contains a know virus.
  2. The file attachment type is blocked because viruses and other malicious code often spread this way. Some file types are quarantined and others are blocked. Any e-mail with an exe, pif, scr, or vbs attachment will be discarded. File attachments such as bat and reg are quarantined. In any case, the file can be archived or zipped and sent. The spam firewall does not currently block anything in archives except for viruses.
