Hello Boaz,
Are you implying that environment variables cannot be created by a program
other than a shell? Environment variables are not shell specific.
Sure, shells usually set common variables, but in no way is the
environment shell dependent, just man 7 environ.
As for the REMOTEHOST issue, here is the appropriate code excerpt:
Taken from login.c
"/*
* Add remote hostname to the environment. I think
* (not sure) I saw it once on Irix. --marekm
*/
addenv("REMOTEHOST", hostname);"
As I said before, REMOTEHOST cannot be set by the shell, since the shell has no
way of determining its peer.

the word "unsubscribe" in the message body, e.g., run the command
echo unsubscribe | mail [EMAIL PROTECTED]
