Usereplyto Channel Option

Mapping Reply-to: header when gatewaying to non RFC 822 environments
The  channel option controls the mapping of the Reply-to: header in certain non RFC 822 environments. (Currently, the  channel option is relevant only for the OpenVMS local channel, and the PMDF-LAN cc:Mail, GroupWise, and Microsoft® Mail channels.) The default argument for   is 0, which means to use the channel default behavior (which varies from channel to channel).
