Mailfilter is a flexible utility to get rid of unwanted spam mails, before having to go through the trouble of downloading them into the local computer. It offers support for one or many POP accounts and is especially useful for dialup connections via modem. You can define your own filters (rules) to determine which e-mails should be delivered and which are considered waste.
Re: Cool ! Mailfilter knows "black-" and "whitelistst", but you can not use any of the automatically generated ones that are distributed via various sites.
