Please don't cross-post. It creates food fights between the various
factions.

The Solaris 9 man page for mailx offers this environment variable
description:

returnaddr=string
The default sender address is that of the current
user. This variable can be used to set the sender
address to any arbitrary value. Set with caution.

No reason to think it is found in all mailx versions, and may not
accomplish what you wish.
