cPanel MailScanner Configuration
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".
On 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 "spam@yourdomain.com" 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 your domain.
- 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)..
Other Settings
- 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 false-positives.
- 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 "spam@yourdomain.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 select it.
