Set up mail filters to decrease junk mail (also known as spam) in your e-mail inbox. This basic form of filtering uses the spam status header to filter junk mail into a separate folder.
Note: FirstClass Client software is used with FirstClass mail servers. However, the changes made to the mailbox using FirstClass Client will affect mail filtering in the user's FirstClass account, whether viewed by FirstClass Client or any other mail client connecting to the FirstClass server.
These procedures apply both to the FirstClass Clients for Windows and Macintosh. Very minor differences are noted.
