Email filters for Entourage for Mac OS X
X-Spam-Flag filter
An X-Spam-Flag filter will catch only messages whose
hits percentage meets or exceeds the 50% threshhold
currently used by NC State. It will function only when
the X-Spam-Flag header has a value of YES. Before you construct a spam filter, be sure to set up a spam folder in the Inbox
of your email client so that you can
retrieve
any legitimate messages caught by the filter.
NOTE: If you have already set up this
type of filter for the SpamAssassin software previously
used at NC State, you do not need to add a
new one for PureMessage.
To construct
a spam filter based on the PureMessage X-Spam-Flag
header:
- Open Entourage.
- From the Tools menu, select Rules.
- Select the IMAP tab.
- Select New.
- Give the rule a name, e.g., spamflag.
- Under If, select the Execute pull-down
menu.
- Choose if any criteria are met.
- From the next pull-down menu, select Specific
header.
- In the first text box, type: X-Spam-Flag.
- From the second pull-down menu, select contains.
- Type Yes in the text box.
- Under Then, from the first pull-down menu,
choose Move Message.
- From the second pull-down menu, select your spam
folder.
- Make sure the Enabled check box is marked.
- Select OK.
X-Spam-Level filter
An X-Spam-Level filter can be used to catch messages
whose hits percentage is less than the 50% threshhold.
You might want to create one if you feel that 50% is
too high (doesn't catch enough spam). If you choose
a threshhold that is not a multiple of 10 (e.g., 45%),
you will need to create two of these filters instead
of one. Before you construct a spam filter, be sure
to set up a spam folder in the Inbox of your email
client so that you can
retrieve
any legitimate messages caught by the filter.
WARNING: Be very careful if you create
an X-Spam-Level filter. The lower the hits percentage
you choose for filtering, the more likely you
will mistakenly catch legitimate mail and send it to your spam folder.
To
construct a spam filter based on the PureMessage X-Spam-Level header:
- Open Entourage.
- From the Tools menu, select Rules.
- Select the IMAP tab.
- Select New.
- Give the rule a name, e.g., spamlevel.
- Under If, select the Execute pull-down
menu.
- Choose if any criteria are
met.
- From the next pull-down menu, select Specific
header.
- In the first text box, type: X-Spam-Level.
- From the second pull-down
menu, select contains.
- Type in your chosen hits percentage using the letters
X and/or I:
- If your percentage is a multiple
of ten, type a number of X's equal
to the tens digit of the percentage.
For example, for 60%, you would type 6 X's (upper case):
XXXXXX
- If your percentage is not a multiple
of ten, type a number of X's
equal to the tens digit followed by a number
of I's equal to the ones digit.
For example,
for 65%, you would type 6 X's and 5 I's
(upper case):
XXXXXXIIIII
NOTE: In this case, you will need to create a secondary filter
(see below).
- Under Then, from the first pull-down menu
choose Move Message.
- From the second pull-down menu, choose your spam
folder.
- Make sure the Enabled checkbox is marked.
- Select OK.
If your hits percentage is not a multiple
of 10, you will need to create a secondary
filter:
- From the Tools menu, select Rules.
- Select the IMAP tab.
- Select New.
- Give the rule a name different from the
one above, e.g., spamlevel2.
- Under If, select the Execute pull-down
menu.
- Choose if any criteria are met.
- From the next pull-down menu, select Specific
header.
- In the first text box, type: X-Spam-Level.
- From the second pull-down menu, select contains.
- Type in a number of X's equal to one more
than the tens digit of your chosen hits
percentage.
For example, for 65%, you would type 7 X's (upper case):
XXXXXXX
- Under Then, from the first pull-down menu
choose Move Message.
- From the second pull-down menu, choose your spam
folder.
- Make sure the Enabled checkbox is marked.
- Select OK.
X-Virus-Detected filter
By using an X-Virus-Detected filter and creating a
virus folder in the Inbox of your email client, you
can retrieve legitimate messages that arrived with
virus-laden
attachments
that were later removed by PureMessage. Be sure to
set up your virus folder before you construct
a virus filter.
To construct a virus
filter based on the PureMessage X-Virus-Detected header:
- Open Entourage.
- From the Tools menu, select Rules.
- Select the IMAP tab.
- Select New.
- Give the rule a name, e.g., virus.
- Under If, select the Execute pull-down
menu.
- Choose if any criteria are met.
- From the next pull-down menu, select Specific
header.
- In the first text box, type: X-Virus-Detected.
- From the second pull-down menu, select contains.
- Type yes in the text box.
- Under Then, from the first pull-down menu
choose Move Message.
- From the second pull-down menu, choose your virus
folder.
- Make sure the Enabled checkbox is marked.
- Select OK.
