fastforward handles qmail forwarding according to a cdb database. It can create forwarding databases from a sendmail-style /etc/aliases or from user-oriented virtual-domain tables. fastforward supports external mailing lists, stored in a binary format for fast access. It has a tool to convert sendmail-style include files into binary lists.
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.
