Netscape 6.2.1 does not allow you to create custom filters, so users of this version are unable to take advantage of the special headers used in their mail client software at this time.

Netscape 4.7.8 allows you to create a custom filter. You can supply the special x-header information to Netscape 4.7.8 by doing the following:

1. In the pull-down bar at the top of your Netscape 4.78 window, go to "Edit: Message Filters". A new window will open.
2. Click "New". Click "Advanced". A new window will open.
3. Enter "X-Spam-Flag", click "Add", and click "OK". The latest new window will close.
4. In the pull-down list, select "X-Spam-Flag".
5. In the "contains" box, enter "X-Spam-Flag: Yes".
6. In the "Perform this action" pull-down list, select "move to folder".
7. Click "new folder" and create a Spam folder. It should then be selected in the pulldown list of your folders.
8. Click OK.
The next time you check your mail, check to see if any messages were automatically filtered into your Spam folder!

1. From the menu bar, choose Tools, then Rules.
2. Select POP, and then hit "new" for a new rule.
3. Under the section marked "If", choose "specific header" and then type or paste in the name of the header, which is "X-Spam-Flag".
4. Under "Contains:" type in Yes.
5. In the section marked "Then", specify an action -- move to a new folder, change its status or color, as you see fit. Note that we do not recommend simply deleting messages found by this rule.
6. The Enabled box needs to be checked in order for this rule to be active - it will be checked by default.

1. In the menu bar, click 'Mailbox' then 'New Mailbox' and create the mailbox you want the Spam to end up in.
2. In the menu bar, click 'Mail' then 'Preferences...'
3. Click 'Rules' then 'Create Rule'.
4. Add a description of the rule, then click the 'From' Criteria, then click 'Expert...'
5. In the Header: field enter 'X-Spam-Flag', click 'Add Header' and 'OK'
6. Now click 'From' and select 'X-Spam-Flag'. Select 'Contains' in the next box and enter 'Yes' in the third Criteria box.
7. In the Action section, check 'Transfer to mailbox' and select the desired mailbox. Click 'OK'.
8. Adjust the rule priorities if you want, and dismiss the Mail Preferences dialog box.
9. The next time you check your mail, check to see if any messages were automatically filtered into your Spam mailbox!
