By SoftCns Editor: Everyone owning an email address knows these annoying mails you receive. The number of spam mails running around is continuously increasing so everyone has to spend more time sorting out good mails from spam. Don't waste time on this, let SpamAware do it for you! SpamAware is a plug-in for MS-Outlook, Outlook Express and Windows Mail (Vista). It uses SpamAssassin to score new incoming mails and decides, based on the settings made in options, what to do with the mail. It contacts several spam-servers through SpamAssassin to be more efficient. The application is completely functional after installation and gets automatically active on new mails.
It supports Black- and Whitelist filtering, Bayes and is able to automatically add all your Outlook contacts and
add recipients of mails you write to the Whitelist.
