hi friends,
im using mutt to send mail in c program.i want to change the headers of mail.By googling i came to know that i have to alter /etc/Muttrc or .muttrc file. it is working fine.

say, suppose if i want to change the from address, i can use
set from=jayasekar@xxorg.com
if i want to change the host name
set hostname=xxorg.com # some thing like this


i want the mail header as given below

From: xxorg<noreply@xxorg.com> // i can use "set from"
To: jayasekar@xxorg.com
Delivered-To: jayasekar@xxorg.com
Return-Path: support@xxorg.com

if i use "set envelope_from=yes" then return-path and from address are same. But i want it to be different from-address and different-return path.
Can any one help me ??

Thanks in advance
