The Aerospace Spam Filter is an integral part of the e-mail system that keeps users secure and makes our e-mail system viable as we average over 5000 e-mail messages an hour and 125,000 per day. Without the Spam Filter, each user would have an impossibly large inbox overloaded with useless spam.

To edit your personal e-mail account preferences for the Aerospace Spam Filter:

1. Open the web-browser of your choice and go to https://barracuda.aero.und.edu

1. Enter the user name and password into the proper fields. (This will be the same as your email account user name and password.) User name example: AeroUser@aero.und.edu would put “AeroUser” into the user name field.
2. Click the 'Login' button.

1. Log into the Barracuda Spam Firewall
2. On the same line as the piece of mail, click the link marked “Deliver”

This will remove the mail from the quarantine and send it into your regular inbox.

If you've received a piece of mail in which you wish to block or “blacklist” the sender, you can do one of two things.

1. If the mail is in your quarantine inbox, all you need to do is click the link marked “block” on the same line as the piece of mail.
2. If the mail is not in your quarantine inbox, click the preferences tab and type the e-mail address that you wish to block into the area marked “Blocked Email Addresses and Domains” and click Add. Once you do this the page should refresh and you will see the address you just added put into a list below.

• Click on the Trashcan icon to remove the address from the blacklist.

If you want to be certain that a specific e-mail address will not get caught in the quarantine the address must be white listed.

1. Click Preferences Tab
2. Enter e-mail address in the text-box in the field “Allowed Email Addresses and Domains (Whitelist)” and click Add. Notice that the address should show up in a list below the text-box in which it was entered.

• To remove an address from the whitelist, click on the Trashcan icon next to the address in the list. It will then disappear from the list.

• When classifying a message in the quarantine as “spam” or “not spam”, what is actually happening is that the message is picked apart word-by-word and the words are tallied to determine what types and concentrations of words are used more often in “spam” or “not spam” e-mails. It uses this information when skimming incoming mail messages for high concentrations of words that are used in either spam or legitimate e-mails.
• In order for the classifications to be more accurate, there must be more “not spam” listed than “spam” and it works more accurately if there is more than 200 of each type of message classified. We know that this would be a difficult task and as such, we have set this type of filtering up for all e-mail that comes into the spam filter. If you wish to set up your own classification, it will be an extra filter of your own account, beyond what SCC has already set.

If you run into trouble, are uncertain of what to do for a specific piece of mail or wish to bring any spam to our attention, please send it to spam@aero.und.edu.

Keep the following in mind when sending to spam@aero.und.edu

1. If individual text or characters cannot be highlighted with the mouse cursor within the mail, we cannot block the piece of mail currently.

If you do not receive an e-mail that you know was supposed to have arrived without a doubt. Send your concerns to notspam@aero.und.edu

We would ask that you consider the following before alerting us at notspam@aero.und.edu:

1. The sender may not have actually sent or responded to an e-mail yet.
2. E-mail is not always instantaneous and there are many reasons for delay. Please give at least 20 minutes after you are certain an e-mail was sent before alerting us.
3. If you receive a piece of mail that has ”[SPAM?]” at the beginning of a subject line, it was most likely inserted by the spam filter because it is only possibly spam. It will not block such a message, it only wishes to add the ”[SPAM?]” tag as a precaution to the user to let them know that the piece of mail may possibly be harmful. If your inbox has such mark in the subject of the message, all that should need to be done to ensure that future e-mails from the sender do not get tagged is to whitelist the sender in the “Preferences” tab. (See above)
4. Also note that any tagged e-mail will not be blocked at any given time, it is only a warning.
