Vade Retro antispam for Microsoft Outlook and Outlook Express filters up to 99% of spam, scam, phishing, spreading virus and bounce messages. Unwanted messages are moved into folders of their own, for you to browse and / or remove at your convenience. Spam changes, so does the filter, which is constantly updated by the Vade Retro team at GOTO Software. Automatic update of the filter is subscription-based.
