I have a server running python, php, perl, ruby, and I have couple applications which also send mail. I was wondering in case if one of the applications don't specify a from email address, the sender email address is set to [email protected] and the sender name was "http".
I was able change the sender name by going into /etc/passwd and changing the name to what I wanted, but how do I change [email protected] to [email protected]?

Once you have access to the disk, Postfix stores email in /var/spool/postfix , in a binary format that you really want the postcat(1) tool to extract in human readable format.
You can use the smtp_generic_maps of postfix to rewrite email headers for outgoing smtp mail:
user:~$ echo "[email protected] [email protected]" >> /etc/postfix/generic
user:~$ echo "smtp_generic_maps = hash:/etc/postfix/generic" >> /etc/postfix/main.cf
user:~$ postmap /etc/postfix/generic
user:~$ service postfix restart
