19.1.2. Antispam Operation
The BitDefender Antispam Engine uses all antispam filters combined to determine
whether a certain e-mail message should get into your Inbox or not.
Important
The spam messages detected by BitDefender are marked with the [SPAM] prefix
in the subject line. BitDefender automatically moves spam messages to a specific
folder, as follows:
⚫ In Microsoft Outlook, spam messages are moved to a Spam folder, located in the
Deleted Items folder. The Spam folder is created during the installation of
BitDefender.
⚫ In Outlook Express and Windows Mail, spam messages are moved directly to
Deleted Items.
⚫ In Mozilla Thunderbird, spam messages are moved to a Spam folder, located in
the Trash folder. The Spam folder is created during the installation of BitDefender.
If you use other mail clients, you must create a rule to move the e-mail messages
marked as [SPAM] by BitDefender to a custom quarantine folder.
Every e-mail that comes from the Internet is first checked with the Friends
list/Spammers list filter. If the sender's address is found in the Friends list the e-mail
is moved directly to your Inbox.
Otherwise the Spammers list filter will take over the e-mail to verify if the sender's
address is on its list. The e-mail will be tagged as SPAM and moved in the Spam
folder (located in Microsoft Outlook) if a match has been made.
Else, the Charset filter will check if the e-mail is written in Cyrillic or Asian characters.
If so the e-mail will be tagged as SPAM and moved in the Spam folder.
If the e-mail is not written in Asian or Cyrillic it will be passed to the Image filter.
The Image filter will detect all the e-mail messages containing attached images
with spam content.
The URL filter will look for links and it will compare the links found with the links
from the BitDefender database. In case of a match it will add a SPAM score to the
e-mail.
The NeuNet (Heuristic) filter will take over the e-mail and will perform a set of tests
on all the message components, looking for words, phrases, links or other
