BSD Vacation v2 is a rewrite of the 'vacation'
program that has come with Sendmail (and thus
*BSD) since about 1983. This version has been
almost completely rewritten in an attempt to get it
closer to RFC-2822 compliance than any previous
version. It properly responds to the correct
recipients, as per the RFC, and it correctly handles
multi-line headers. The command-line interface is
compatible with previous versions, and most recent
add-on features from the various *BSD projects
have been implemented, such as support for
preloading the recent recipients database.
