I wanted the ability to use DNS to verify if an email address COULD be valid by checking for valid MX records. This could be used for sender verification for emails with a program such as MIMEDefang or for websites to verify email addresses prior to registering users and/or sending a confirmation email.
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.
Problem reports, updates or suggestions for this package should be reported with send-pr.
