The Gentoo mailx - 8.1.1 - does not utilize the REPLYTO environment variable. This prevents me from sending external email from the command line as replies need to be sent to a POP server rather than the originating address. Debian Woody uses 8.1.2, which does respect REPLYTO, along with several extra variables. TIA.
