Greymail Help
Introduction
Greymail is the result
of the virus and spam
filtering options.
Whenever the Virus
Scanner or the Spam
Filter catches a message
that is identified as a
virus or as spam, they
will re-direct the
message to Greymail.
Greymail is essentially
a quarantine area to
contain these
undesirable messages.
All Greymail is
configured to
automatically delete
after a period of 14
days or less, depending
on the user configurable
setting. You may delete
messages, forward
messages, read messages,
and configure a list of
users that you always
want to receive mail
from.
Spam Scoring
Every email you receive
passes through the Spam
filtering system, which
analyzes the message,
looking for certain
traits normally found in
Spam. There are hundreds
and hundreds of traits
the filtering system
scans for; all capital
letters in the body of
the message, an
Unsubscribe link, no
name in the From: line
are just a few. If only
one of these traits is
found in a message it
will be assigned a low
Spam score but if a
message has many of
these traits it will be
assigned a higher score.
This is how it is
decided whether a
message should be sent
to your Inbox or to
Greymail. The Spam
Threshold point scale
that you can adjust in
your Greymail Options
sets the bar for the
delivery to your Inbox
or Greymail (Spam
repository).
When in Greymail, click
the View Message Header
icon.
The line that reads
X-X5: Spam: True; 6.4 /
5.0 means that this
message scored a 6.4
because of the Spam
traits that were found
and your Spam Threshold
is set to 5.0, so this
message was sent to
Greymail rather than
your Inbox. If you find
that legitimate email is
being quarantined in
Greymail check this
X-X5: Spam: True line
and tweak your Spam
Threshold setting until
the messages clear
filtering.
Spam Confidence
The Confidence Threshold
of your Greymail Options
lets you decide at what
score a message should
not appear in the
"Normal" confidence tab
of the message list. Any
message that scores
above what you have set
in the Confidence
Threshold should rarely
need review, and will be
listed under the "High"
confidence tab. All
messages, regardless of
score, will be shown
together under the
"Both" confidence tab.
Functions:
Deleting a message:
To delete a message or a
collection of messages,
select the checkbox to
the left of each
message, then hit the
delete button at the top
of the screen.
Viewing a message:
To view a message, click
on the subject. If the
message has no subject,
you may click on the
envelope to the right of
the date field to pull
up the message. This
will launch a new
window. If the message
contains attachments or
inline images, it will
not display for security
reasons. In this case,
if the message is spam,
you can forward it on to
your normal email client
and read it. Headers are
not included in the
message display. In
order to view headers,
click on the header icon
next to the envelope. To
view a message with
unsafe images (web bugs)
click on the magnifying
glass.
Forwarding a message to
your normal email
account:
To forward on a message,
simply check the
checkbox to the left of
it, then hit the forward
button at the top of the
screen.
Allowing mail from
sender:
To allow messages to
pass through your spam
filter, you can select
the message by checking
the checkbox to the left
of the message, then hit
the 'Allow Sender'
button at the top of the
page. This will add the
sender's email address
to the white list which
is a list of users that
you will always receive
mail from, regardless of
whether they are spam or
not.
Adding, Editing, or
Removing users from your
white list:
To add, edit or remove
users from your white
list, select "Options",
then add, edit, or
remove from the list. In
order to add multiple
addresses, add one, then
save, then another free
input box will appear at
the bottom of the list.
You can use wildcards -
for example, to block
everything from
"my-example-domain.com",
simply put *@my-example-domain.com
on your blacklist. You
can whitelist everyone
from that domain by
placing the same thing
on the whitelist.

messages which have been
