Sendmail Sender Address Validator description
This tool is a lightweight, fast and reliable Sendmail filter that implements a real-time Sender e-Mail Address Verification technology. This technology can stop some kinds of SPAM with a spoofed sender's e-Mail address. Also it implements a real-time Recipient e-Mail Address Verification technology. It can be useful if your machine is a backup MX for the recipient's domains or if your machine forwards all e-Mail messages as a relay host for your domains to another internal or external e-Mail servers. Features: - external editable configuration file; - whitelist by an IP address (in CIDR notation); - whitelist by a PTR (reverse DNS) record; - whitelist by an envelope sender e-Mail address; - whitelist by an envelope recipient e-Mail address; - scalable and tunable fast in-memory cache engine; - SMTP AUTH support; - strictly RFC-2821 compliant MX callback engine; - tolerance against non RFC-2821 compliant e-Mail servers; - blocking of e-Mail messages with a spoofed sender's e-Mail address; - recipient's e-Mail address verification with authoritative e-Mail stores (call ahead technique); - progressive slowdown of recipient's e-Mail address brute force attacks; - Sendmail virtusertable and mailertable features full support.
