System, method and computer program to block spam |
摘要 |
A system, method and program product for blocking unwanted e-mails. An e-mail is identified as unwanted. A source IP address of the unwanted e-mail is determined. Other source IP addresses owned or registered by an owner or registrant of the source IP address of the unwanted e-mail are determined. Subsequent e-mails from the source IP address and the other IP addresses are blocked. This will thwart a spammer who shifts to a new source IP address when its spam is blocked from one source IP address.
