Filtering Your Tagged Messages With Netscape Message Filters

Unsolicited commercial email, also known as SPAM, often uses the BCC (Blind carbon copy) function to reach many people at once. Most mailing lists are sent out the same way. Here's how to set up a new filter to filter the unsolicited mail:


  • Launch Messenger.
  • In Messenger, go to the File menu and select New Folder.
  • Create a folder called by typing the name exactly like this: [JSpamFilter]
  • Go to the Edit menu and choose Message Filters
  • Click New.
  • In the window that opens, enter a filter name [JSpamFilter]

For your filter criteria:

  • Leave the field that says "subject" as is.
  • Leave the field that says "contains" as is.
  • In the blank field to the right, type [JSpamFilter]
  • Leave the field that says "Move to folder" as is.
  • In the field that says "Inbox", click the dropdown arrow and select the folder you'd like to have the spam moved to. (If the folder is not already created, you will have to create it first; and then select it from the list.)

The reason it is not a good idea to put those filtered messages directly in the Trash folder is that you may now or at some point subscribe to mailing lists. Messages sent by mailing lists will be caught in the spam filter as well because the mailing lists don't address you directly but use BCC instead, as did that spam.


To prevent legitimate mass-mailings
from being filtered as spam:

  • When you get a mailing list message flagged in the spam folder, note the address it came from.
  • In Messenger, go to the File menu and select New Folder. Create a folder called something like "publications".

For the filter criteria:

  • In the field that says "subject", click the dropdown arrow and select Sender.
  • Leave the field that says "contains" as is.
  • In the blank field to the right, type the email address of the legitimate mailing list's sender.
  • Leave the field that says "Move to folder" as is.
  • Ensure that this mail filter comes BEFORE the spam filter. You can reorder the filter list by dragging and dropping the list items.

Netscape compares the headers on the email as it is received in the order of the mail filters you have set up. For example, the filter may see that an email came from someone who sends you daily or weekly publications called "maillist.com", so it moves it to the "publications" folder. If the email is not from maillist.com, the email is reviewed by your other mail filters until it reaches the filter that says "To or CC" doesn't contain (your email address)", at which point the message is moved to your "spam" folder.

Once a week, or so you should go through the spam folder to capture and store any messages that should not have been collected as spam. Use them to create additional filters and delete the rest of them.
