The mail gopher (mopher) is an extension to all mail transfer agents that implement the Sendmail Milter API. It reads a list of rules and acts on each incoming mail delivery attempt based on various criteria and existing states. Mopher supports indiscriminate and selective grey- and whitelisting of either individual addresses or whole domains (based on reverse lookups and rules provided by Mozilla's Public Suffix List). Access to tables and state-related data passes through a generic interface and is then translated by one of the available backend drivers.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
