Santronics Software, Inc. introduces WCSAP, a new email caller-id verification anti-spam blocking system with a result rate as high as94%!

(PRWEB) May 20, 2004 -- Continuing its efforts to add more anti-spam capabilities into its flagship product, Wildcat! Internet Net Server (WIN Server) email system, a small South Florida firm, Santronics Software, Inc., (http://www.santronics.com) has introduced a new sender authentication protocol called WCSAP.

WCSAP is analogous to a Caller ID verification system. By far, the top problem with spammers is "spoofing" behavior where spammers do not
provide accurate return addresses. Similar to the US Postal Service, the return address on a postal envelope allows the service to return the
letter to the sender. Email also have return addresses, however spammers provide fake addresses called spoofed return addresses which prevents the internet email system from returning unwanted or bounced mail.

WCSAP works by making the attempt to verify the existence of a valid return address before allowing the sender to continue to send the mail.
If the return address does not exist or cannot be verified, the mail is blocked. If the return address exists, the mail is allowed to continue
to the next check the mail system may employ.

According to Hector Santos, CTO of Santronics Software, "WCSAP is blocking spoofing spammers by an average of 90-94%, which proves that
most spam are from spoofed systems. Part of the problem is that spammers have exploited certain loopholes in the email SMTP technology. While most systems perform minimum checks, verifying the return address is typically not one of them."

WCSAP is not the first system of its kind. Others such as Verizon.net, already implement a return address verification check. However, WCSAP
goes a bit further in becoming essentially an SMTP standards compliancy testing software, the first of its kind. "What is unique about WCSAP is
that it performs a series of technical conformity checks, including a test for open relay sites. While there are many new anti-spam proposals being
researched, WCSAP works today with current standards. The new proposals require change in the industry which is not a guarantee," said Mr.
Santos. Verifying the return path is just one part. WCSAP must first be able to connect to the return address mail server in order to verify the
return address. If the connection fails or the remote site does not exist, the transaction is blocked. If the remote site accepts a return
address, a 2nd check is performed to see if it is an open relay by giving a completely random return address.

WCSAP is now included with the v6.0 Wildcat! Interactive Net Server release, distributed electronically to subscription customers, and will begin shipping on CD in early June. wcSAP also features options which comply with the recently signed CAM-SPAM legislation. Mr. Santos adds, "With CAN-SPAM, Spammers are now legally required to provide valid return addresses. WCSAP will offer our customers the ability to verify, track and audit mail transactions to make sure spammers are in compliance with the technical standards and, now, the law. WCSAP is CAN-SPAM friendly!"
