MAPS Transport Security Initiative MAPS SM Transport Security Initiative Junk email is a significant security problem for computer system administrators and vendors.
Spammers steal resources, disrupt operations, and damage systems.
We need to develop new techniques to secure our mail transports against these vandals. The MAPS SM TSI works in conjunction with the sysadmin and vendor communities to develop the knowledge and tools to combat the junk email problem. If you are a WebTV user in need of assistance, please see this page. If so, then it's only a matter of time before spammers hijack your mail server. The threat is real, and the problem is happening now .
