18.1.1. Antispam filters
The Bitdefender Antispam Engine incorporates cloud protection and other
several different filters that ensure your Inbox to be SPAM-free, like Friends
list, Spammers list and Charset filter.
Friends list / Spammers list
Most people communicate regularly to a group of people or even receive
messages from companies or organizations in the same domain. By using
friends or spammers list, you can easily classify which people you want to
receive email from (friends) no matter what the message contains, or which
people you never want to hear from again (spammers).
Note
We recommend that you add your friends' names and email addresses to the
Friends list. Bitdefender does not block messages from those on the list;
therefore, adding friends helps ensure that legitimate messages get through.
Charset filter
Many spam messages are written in Cyrillic and / or Asian charsets. The
Charset Filter detects this kind of messages and tags them as SPAM.
18.1.2. Antispam operation
The Bitdefender Antispam Engine uses all antispam filters combined to
determine whether a certain email message should get into your Inbox or
not.
Every email 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 email is moved directly to your Inbox.
Otherwise, the Spammers list filter will take over the email to verify if the
sender's address is on its list. If a match is made, the email will be tagged
as SPAM and moved in the Spam folder.
Else, the Charset filter will check if the email is written in Cyrillic or Asian
characters. If so the email will be tagged as SPAM and moved in the Spam
folder.
