The time has come to move to 100% spam rejection. Nearly every Internet user has access to some level of spam filtering but spam leaks through no matter how good the filter. Today's trickle soon becomes a flood. Consider. You control access to your house by inviting inside only people you approve. You don't just leave the front door open and then try to evict people after the fact. SpamAI version 4 now controls your inbox the same way you control your front door: the only email reaching your inbox is email you allow in. To understand how big a change this is, note that magazine reviews of anti-spam solutions make a big deal about "out of box" performance and "false positives". According to magazine reviewers, locking your front door to everyone initially is wrong. Well, tough. Immediately after SpamAI is installed, no email reaches your inbox until you allow it in. Period. In SpamAI, you preview email in a holding tank that immunizes you from malware. The holdtank displays text only and malware simply does not have a chance to affect you, another huge change from the current practice. Of course, your email program can open any email you explicitly allow out of the holding tank where the usual cautions still apply. By simple point and click, you are building rules for what you want to receive automatically in the future. A convenient identity confirmation checkbox tests that email you allow is sent only from the same organization in the future. SpamAI permits searching all archived messages for four weeks so that inadvertently declined email can still be recovered. SpamAI supports all POP3 email clients, including Outlook, Outlook Express, Thunderbird, Eudora, TheBat!, Courier, Poco Mail, Mozilla, and many others.

SpamBurner is more than a spam filtering tool, it is also a great e-mail reader, which can help protect you from e-mail based viruses as well (as it allows viewing of messages in text form, even if the message has complex HTML and Javascript coding! SpamBurner strips it down, and makes it readable -- plus, if you have Microsoft's Outlook or Outlook Express installed on your system, you can conveniently open the message with Microsoft's e-mail viewer from within SpamBurner if you want to see the HTML code, pictures, etc... without having to download the message into your e-mail program's inbox! ...so if it's spam, it won't even have a chance to clutter up your e-mail.) SpamBurner supports the POP3 e-mail protocol, will work through most types of proxies, and supports an unlimited number of e-mail accounts. It also works with Yahoo! Mail and other web-mail services that offer a POP3 capability. It can also clean up offline e-mail in Qualcomm Eudora and Microsoft Outlook e-mail programs. SpamBurner also has a really powerful WHOIS-Lookup feature (we call it AutoWHOIS), which lets you do WHOIS lookups from any hostname OR IP address -- it also is able to auto-detect the appropriate WHOIS servers, and it is integrated with SpamBurner's message viewer -- you select the part of the message headers you want to do a WHOIS on, and right-click, then click WHOIS. AutoWHOIS also supports proxy servers.
