If you receive mail from your ISP using POP3 then WorkgroupMail can provide a useful way of filtering out mail that you do not want to download from the server.
For example, you can compile a list of mail originators that send you junk mail and you can instruct WorkgroupMail not to download mail sent from these originators. Additionally, you might wish to specify that no mail larger than 20MB will be downloaded. Both these scenarios and more are possible using the Filtering page of the ISP Options property sheet.
