smf-sav is a high-performing and dependable email verification tool for Sendmail. It operates as a real-time Sender e-Mail Address Verification solution while keeping it lightweight and fast.
Written in C, Sendmail Sender Address Validator boasts several key features. These features include a friendly host/network whitelist, SMTP AUTH support, RFC-2821 compliant MX callback engine, tolerance against non RFC-2821 compliant e-Mail servers, blocking of e-Mail messages with spoofed sender's e-Mail addresses, and recipient's e-Mail address verification with an authoritative e-Mail store in gateway mode. The software also includes a slow-down of recipient's e-Mail address brute force attacks in gateway mode.
In the latest release, users can take advantage of whitelisting by a PTR (reverse DNS) record or an envelope recipient email address. Additionally, the new option to ignore tempfailed SAV results can help prevent unnecessary rejections. Users can also refuse email messages from systems that don't accept the null reverse-path, and tempfail and fail results TTL settings have been segregated. Finally, a progressive slowdown of brute force attacks on a recipient's email address was implemented.
Overall, if you're looking for reliable anti-SPAM software that's both fast and efficient, Sendmail Sender Address Validator is certainly worth considering. With its wealth of features and recent updates, it's a reliable choice for businesses and individuals alike.
