Who needs Mailfilter?
If you do not pick up your e-mail from a POP server, then there is no need to install Mailfilter. But if you do get your e-mail from one or many POP accounts and if you are sick and tired of downloading megabytes of worthless spam (usually those are anonymous advertisements, chain mails, etc.), then you should give Mailfilter a try. It will help save you band width and time by deleting spam directly on your server, before you have to download and read those messages. By defining your own personal filter rules, you can tell Mailfilter which e-mails should be deleted.
