Bulk E-mail or Unsolicited Commercial E-mail (UCE) - SPAM
by another name - is a growing concern
at UNT and across the nation/world. The Network Computing Services
Team provides bulk E-mail filtering to help you manage this type of mail
better. E-mail that is likely unsolicited now includes the word "BULK:"
before the subject of the message.
This E-mail filtering has been going on for some time now and you should be familiar with the spam filter that
actively evaluates messages based on their content to determine
if they are likely to be undesirable bulk mail. There is a
tutorial, called
GroupWise
"BULK:" E-mail Filtering , that will teach you to create a rule to
filter this mail out of your main inbox and redirect it to
another folder. You will need to take this tutorial before
attempting to Whitelist your GroupWise mail (described below).
As some have noticed, the process of defining mail as BULK:
is not a foolproof endeavor. On occasion, E-mail that comes from a
legitimate source is mistakenly labeled as BULK:. Legitimate
mail that is mistakenly marked BULK: is known as a "false
positive." The question is now, how can I make sure that false
positive E-mail is not filtered into my BULK mail folder or sent
to the trash (which ever location you have decided to redirect
your BULK: tagged mail)?
Whitelisting your E-mail, a tutorial
The answer is to "whitelist" your E-mail. Whitelisting
E-mail
is the process by which you tell GroupWise that even though a
message is tagged as BULK, it belongs to a trusted group of
E-mail senders and should not be filtered along with undesirable
mail.
NOTE: This tutorial is a companion to the
GroupWise "BULK:"
E-mail Filtering tutorial. Complete this
tutorial only after completing the BULK mail tutorial or it will
not work. This tutorial is also available on the NCS Website
here.
Step 1) Create the rule to identify legitimate E-mail.
- From the Tools menu, select Rules.
- In the Rules window, click "New..."
- Name the Rule "Whitelisted BULK Mail"
- When event is... New Item, mark the
checkbox labeled "Received" (should be the
default).
- If conditions are ... make sure none of the boxes are
checked.
Step 2) Define the filter
- Click the "Define Conditions..." button and refer to the
image for an example and explanation below.
|
Your filter definition should
follow this example. I'll explain:
A) The first line of the filter should read
exactly like the example above.
Subject |->(begins
with) BULK: End Group
This line tells GroupWise to look for
mail that is tagged BULK: in the beginning of the
subject line.
B) After you enter End Group
at the end of the first line, a drop down menu appears
centered below.
And - This will begin a
second series of filter parameters.
From []
(contains) E-mail@ddress.com
Or/End
This second series of parameters is the list of
E-mail
addresses that you want to whitelist. In the first line
I have entered '@domain.com' which tells GroupWise that
mail from this E-mail domain fits my description of
legitimate E-mail. This of course could be substituted
with "@aol.com", "@charter.net", "@thisorthat.org", etc.
By using a generalized E-mail domain you will allow all
mail from this domain to pass, regardless of who sent
it.
In the second line I have narrowed my criteria down
to a specific person in a specific E-mail domain.Why? You
may find it desirable to let some @yahoo.com users to
E-mail you, but not ALL E-mail users from @yahoo.com
to E-mail you. You should use your best judgment as to
which type of filter to adopt for each whitelisted
entry.
NOTE: It is important that when
identifying multiple E-mail addresses to whitelist that
you separate each line with the "OR"
argument. If you use "and" then ALL criteria must be met
for the rule to work, and this is not the effect you
want for this rule.
C) At the end of your last E-mail filter entry, select
End.
Later when you are editing this rule to add more
entries to your white list, change the End
statement in the last line to Or.
Changing the last argument to Or will
spawn a new line.
D) Click OK to complete the filter. |
Step 3) Define the Action
- From the "Add Action" drop down menu,
select "Move to Folder".
- A window will appear that allows you to browse your
GroupWise account, mark the checkbox next to your mailbox then
click "Move."
Step 4) Place the Whitelist rule above your Bulk Mail
rule.
- Click on the Whitelist rule you have just created and drag
it above your BULK mail rule. (Absolutely
necessary)
You should see a gold arrow appear to the left
of the rule indicating the order you are placing it.
Step 5) Add more names to the rule.
(optional)
- If you need to add more addresses to your whitelist, return
to the Rules window, select the
Whitelist rule, and click the Edit...
button.
- Click the Define Conditions rule and add
more E-mail addresses/domains to your list.
