FGCU’s Spam Firewall provides us with a combination of the
best methods to determine what spam is, and to keep these emails
from clogging up your inbox. All email will either be delivered
to your inbox, delivered to your inbox with [SPAM] added to the
subject line, or quarantined for later review. The device uses
a comprehensive combination of user specified rules, spam fingerprint
checking, keyword scanning, blacklist and whitelist, spam rule-based
scoring, message authenticity checking, and Bayesian algorithms
to quarantine email. These methods are updated hourly to give FGCU
the best spam blocking protection possible.
When the Spam Firewall receives an email for you, it scores the
message for its spam probability. This score ranges from 0 (definitely
not spam) to 10 or higher (definitely spam). Based on this score,
the Spam Firewall either allows, quarantines, or blocks the message
Emails determined to be spam, scoring 3 and higher, are quarantined
to the spam hardware device for review by each user. Emails that
have a possibility of being spam, scoring 1 or 2, are marked by
adding “[SPAM]” to the subject line and delivered as
normal. Each user may set up rules for moving email with [SPAM]
in the subject line to a spam folder in their inbox. Also, users
have the option to teach the Spam Firewall what is spam and vice
The Spam Firewall has the ability to block spam email so it does
not bog down the email servers. Until we are confident that no valid
email is blocked we will not turn this option on. We will notify
the faculty and staff before implementing blocking.
The Spam Firewall provides complete virus protection for all incoming
email in addition to filtering spam. It will eliminate all dangerous
emails that contain viruses. The virus protection methods are updated
hourly insuring that FGCU has the best virus protection possible.
- Once we move the anti-spam solution into production you will
receive the email shown below if you have messages that are
Computer Services recommends that you save this email. The email
will tell each user how to logon to the Spam Firewall to view
your quarantined email.
- Computing Services suggests bookmarking the web address of
the spam firewall for your easy reference. http://spam.fgcu.edu:8000.
- The Spam Firewall sends you a daily quarantine summary report
so you can view the quarantined messages you did not receive in
your inbox. From the quarantine summary report you can add messages
to your whitelist, delete messages, and have messages delivered
to your inbox.
- “All staff” emails and eagle mail (FGCU student
email) will never be quarantined. Over time, quarantined email
will age off the Spam Firewall.
- At the end of every Quarantine Summary Report is a link to the
quarantine interface where you can set additional preferences
and classify messages as spam and not spam. Click the link provided
at the bottom of the Quarantine Summary Report (displayed below).
- The following figure shows an example of a Quarantine Summary
Logon to Spam Firewall
- For your security you must type your user name and password
to access the Spam Firewall. This is the same user name and password
that was emailed to you in the welcome email.
- You must use your full email address including the “@fgcu.edu” in
the username box.
- For security purposes it is important that you change you password
from the initial password sent to you. Changing your password
will be covered in the Setting Up Preferences section later in
- If you have forgotten your password, follow the instructions
for using the Create New Password button at the bottom of the
- After logging into the quarantine interface, select the QUARANTINE
INBOX tab to view a list of your quarantined messages.
When you first start using the quarantine interface, you should
view this list on a daily basis and classify as many messages
as you can.
- The Spam Firewall has a learning engine that learns how to deal
with future messages based on the ones you classify as spam and
not spam. The learning engine becomes more effective over time
as you teach the system how to classify messages and as you set
up rules based on your whitelist and blacklist.
- Clicking on an email displays the message.
||Delivers the selected message to your standard
email inbox.Note: If you want to classify a message or add it
to your whitelist, make sure to do so before delivering the
message to your inbox. Once the Spam Firewall delivers a message,
it is removed from the quarantine list.
Adds the selected message to your whitelist
so all future emails from this sender are not quarantined
the message contains a virus or banned file type.
The Spam Firewall adds the sending e-mail address exactly
as it appears in the message to your personal whitelist.
Note: that some commercial mailings may come from one of
several servers such as “mail3.abcbank.com”, and
a subsequent message may come from “mail2.abcbank.com”.
See the section Preferences > Whitelist/Blacklist for tips
on specifying whitelists with greater effectiveness.
||Deletes the selected message from your quarantine list. The
main reason to delete messages is to help you keep track of
which quarantine messages you have reviewed.You cannot recover
messages you have deleted.
|Classify as Not Spam
Classifies the selected message as not spam.
Note: Some bulk commercial mail may be considered useful
by some users and spam by others. For this reason, classifying
such messages may not be very effective because users may
counteract each others’ classification. Instead of classifying
bulk commercial mail, it may be more effective to add it to
your whitelist (if you wish to receive such messages) or blacklist
(if you prefer not to receive them).
|Classify as Spam
||Classifies the selected message as spam.
Spam in Subject Line
- Emails that have some characteristics of spam but not enough
to be quarantined will be delivered to your inbox and will be
labeled by adding [SPAM] in the subject line.
- You can set up inbox rules that will automatically deliver this
email to a spam folder you create. Setting up inbox rules will
be covered later in this tutorial.
