mail(1) ~R and REPLYTO

[Anton Shterenlikht]

mail(1) man page says:

     ~R string
             Use string as the Reply-To field.

However, this doesn't seem to work for me.
Hitting ~R doesn't have any effect at all.

The man page also has:

     REPLYTO  If set, will be used to initialize the Reply-To field for outgo-
              ing messages.

This does work fine.

Am I doing something wrong?

Thanks

Anton
