Use "nail" instead of "mail". nail is packaged in Fedora Extras. It 
allows you to set the envelope sender - at least I think you mean that 
when your speak about the "from address" in lack of better knowledge (as 
oppose to the header from:). The "sendmail" binary call allows you to 
set the envelope sender as well, by using the "-f user at domain.tld" 
parameter call (both with Sendmail and Postfix). If you instead want a 
header from: set you must do a different mailing which sets the required 
header fields and not simply pipes output into a mail body.
