|Quarantine, discard high score spam
||This would work well for an IMAP client but would be less suitable for a POP3 client.
The tag2 level is set rather low - this keeps the INBOX fairly clean of spam. Mail
that scores between 5 and 8 ends up in the Spam folder. Only a small sample of the
total amount of spam sent to you should end up in the Spam folder. Spam scoring at 8 and above
to the MailZu quarantine and may on occasion contain legitimate mail. It is not
unusual for promotional mail from valid sources (that you may have subscribed to)
to score in this range. Legitimate companies allow you to unsubscribe from their
mailing lists. Anything over 14 is discarded. Any time mail is discarded
there is a potential for loss of legitimate mail, but at a score of 14 that chance
should be reasonably low.
|No spam goes to quarantine
||In this case messages either go to your INBOX or the Spam folder. All messages that score
at 14 or over are permanently discarded. The MailZu quarantine still receives messages
with banned contents (as always).
|Default - all spam to spam folder
||This is the default policy. Any message that scores at 6.5
or over will be placed in the Spam folder. Mail left in the Spam folder over 24 days
is deleted - please move items you wish to keep to another folder.
If using a POP3 client to retrieve mail you will need
to use the webmail interface to access the Spam folder (which is essentially acting as a
quarantine area in this case).
|All spam to quarantine
||Any spam that scores at 8.0 or greater is sent to the MailZu quarantine. Remember that
spam sent to MailZu is deleted after 24 days.
|Permissive, no spam quarantine
||Same as "No spam goes to quarantine" but more permissive.
|Permissive, with spam quarantine
||No spam is sent to Spam folder (which is desired if using a POP3 client) but messages that
score at 10 or above (and less than 25) are quarantined to the MailZu quarantine.
Messages that score over 25 are discarded.
|Nothing goes to spam folder
||This would be especially useful for a POP3 client who does not desire to use
the webmail interface. No spam would be sent to the MailZu interface either. The MailZu
interface would still be used as a quarantine for messages containing banned attachments however.
While a level of 15 seems high remember that many mail clients offer the ability to filter mail
using the contents of mail headers. The filtered mail can then be routed to a folder,
such as a Spam folder. For example, in Thunderbird it is possible to create a custom filter that looks
for a X-Spam-Level header that starts with ****** (6 stars - six points). Unfortunately Outlook
Express does not offer the creation of custom filters based on arbitrary header fields.
|Do not tag or block spam
||All messages (that are not blocked due to virus or banned contents) should be
received in your INBOX.
||Now that you understand the concepts, you decide what is best for you.
