On OpenVMS systems, the Gold-Mail mail user agent, a product of Data Processing Design, Inc., is a commonly used replacement for VMS MAIL.
Gold-Mail provides some added functionality that is not available in
regular VMS MAIL. In particular, Gold-Mail supports read receipts. PMDF
is capable of converting its own read receipt requests into a format
that is compatible with Gold-Mail. In order to activate this feature,
goldmail channel keyword should be used on the channel
that delivers mail to Gold-Mail. This is usually the local channel,
although it is possible for Gold-Mail delivery to be done on d or mail_
channels in some configurations.
nogoldmail keyword disables this feature.
nogoldmail is the default.
