Whitelist
The list of
friends contains email addresses with display names. Messages from these addresses
are autoamtically recognized as non-spam. This check is performed before
the plug-in applies rules uses the statistical classifier. That is why
messages from friendly addresses will never be filtered out as spam.
The following options are available in Training section on the Filtering tab of the
main configuration window:
- Learn messages from friends as non-spam.
Messages from friendly addresses are considered as non-spam and
so training the classifier using them will be good for the classification quality. Sometimes
spammers insert a valid, existing email address to the "From" field, but
the plug-in detects most of these cases and doesn't learn as non-spam the suspicious
messages. The plug-in
automatically removes email addresses in spam (in the "From" field)
from the whitelist.
- Add friends automatically.
The plug-in automatically adds the email addresses of senders from
messages learned as non-spam to the whitelist. You can feed a set of non-spam messages
you have to the plug-in right after the installation. In that case, the whitelist
will be filled with your friends' contact addresses automatically.
- Extract email addresses from message bodies.
Email addresses will be extracted from message bodies and added to the whitelist.
- Use display names during checking the whitelist.
The probability of misclassifying a spam message with a friendly
address is greater than zero. You can make it lower by filling the whitelist
only with addresses having display names. This option prevents the plug-in
from adding addresses without display names to the whitelist when you use non-spam messages to train the
plug-in. When this option is enabled the plug-in checks display
names along with email addresses while classifying incoming messages.
You can edit the whitelist manually in the dialog box for editing friendly addresses.
Also, you can export and import whitelist items from text files on the disk. The
format of these files is compatible with that of files exported from the TheBat Address Book. To
import existing contacts to the whitelist, export items from the Address Book
using the File | Export to | Address list menu item. Then open the Friends dialog box
in the plug-in and import the saved file.
Wildcards are allowed in display names and addresses. For example, you can
specify "*" as a display name if you want the plug-in to ignore it (check
only the email address) for a certain friendly contact. "*@<server>"
as an email address means that all users from that email server are whitelisted.
