cPanel Mail Scanner Configuration
Posted by Salman U on 20 July 2006 09:27 PM
With the MailScanner service you can control what happens to spam
and viruses by changing the configuration in your cPanel control
panel. To access the MailScanner configuration options, login to
your cPanel account and click on "MailScanner Configuration".
the main MailScanner configuration page, if you have only one domain
in your cPanel account you will see two main sections, Current
Settings and Change Individual Domain Settings. If you have more
than one domain, you will see an additional section entitled Change
All Domain Settings. You can change all your domains to the same
settings, or you can configure each domain individually.
Note: Until you change these settings for the first time, they
will show as "Not Set", and mail scanning will be performed as per
the default that your hosting provider has configured.
Mail Scanning Options
- Spam Scanning - If you would like all your
email for this domain scanned for spam, select yes. If you don't
want your mail scanned for spam, select no.
- Low Scoring and High Scoring Spam -
MailScanner assigns a score to each email based on various
attributes and triggers. The higher the score, the more likely
the mail is to be spam. There are two levels of spam, low
scoring and high scoring. High scoring spam is almost certainly
spam, and low scoring spam is probably spam but it's possible to
have false positives. You can also change the level of the low
and high scoring spam; Normally low scoring spam must have a
score of at least 5 but less than 20, and high scoring spam is
email that has a score of at least 20. These score settings can
be changed on a server wide basis by your hosting provider, and
you can also change these scores for your own email (see Other Settings).
When MailScanner determines that an email is low or high scoring
spam, you can configure whether this email is delivered as usual
with a tag to let you know it is spam, deleted so you do not see
it at all, or forwarded to a different email address which you
can check on a regular basis.
If you choose to have the spam forwarded to an alternate email
address you must create this email address in cPanel. You can
either use the default "firstname.lastname@example.org" or set up a
different email address in Other Settings.
- Virus Scanning - If you would like all your
email for this domain to be scanned for viruses, select yes. If
you don't want your email scanned for viruses, select no.
- Deliver Cleaned Emails - Most email viruses
are sent by infected "zombie PCs" and have no valid content. If
you want to receive notifications of each virus that was sent to
you, select yes. If you do not want to receive these
notifications, select no.
Note: Depending on how your web hosting provider has configured
the MailScanner system, by selecting yes you may be able to
receive notifications of emails containing blocked file
attachments which may have been sent to you legitimately. Please
contact your hosting provider to find out whether file
attachments are blocked and if you can receive notifications.
Blacklist and Whitelist Settings
- Spam whitelist - You can add email
addresses or domains to this list that you never want marked as
spam. Please note that emails sent to you from these email
addresses or domains will still be scanned for viruses and
dangerous file attachments but they will not be marked as spam.
Do not add your own domain to this list, as it
will whitelist all emails sent TO your domain as well as FROM
- Spam blacklist - You can add to this list
any email addresses or domains that you want always marked as
high scoring spam. The action you have specified for High
Scoring Spam in the Mail scanning options will be applied to any
emails sent from domains or addresses on this list (i.e. marked
and delivered, deleted, or forwarded).
- Low scoring spam setting - You can change
the level at which MailScanner will identify an email as
low-scoring spam (probably spam) by changing this setting. If
you change it to a higher number you may receive more spams that
have not been identified as spam by MailScanner. If you change
it to a lower number you may find that MailScanner is
identifying non-spam emails as spam, i.e. there will be more
High scoring spam setting - You can change
the level at which MailScanner will identify an email as high
scoring spam (almost certainly spam) by changing this setting.
The default is 20 and this setting works well in most cases. If
you find you are getting excessive amounts of low scoring spam
with a score just below 20, you may want to change this setting
to a lower number, such as 15. If you change it to a lower
number we would recommend NOT setting high scoring spam to
Delete until you've tested it for a while to be sure the new
scoring is working well for you.
- Additional email address - If you'd like to
have spam forwarded to a different email address than
"email@example.com", for instance an email address on another
domain, you can specify that email address here. It will then be
listed as one of the options for Low and High Scoring Spam in
the Mail Scanning Options so you can
