opensmtpd-filter-spfgreylist-1.0.0p0

SPF-aware greylisting filter for the OpenSMTPD daemon

Back to search · Project homepage

Description

This filter implements greylisting, allowing OpenSMTPD to temporarily reject sessions of clients it has not seen before. Unlike many implementations, this one is SPF-aware so it will properly handle greylisting for domains doing relaying through multiple MX, as long as they publish a valid SPF record. The filter currently supports: * IPv4 and IPv6 address greylisting * SPF greylisting * startup whitelisting of IP and domains * automatically renewed whitelisting
