Sending all new and modified passwords to an email address.

Hello!
I have the following problem:
I want that all the passwords for root, accounts and email modified through root or any other way (client, reseller accounts) and new accounts users and passwords (also email accounts) to be sent to a dedicated email address (on the same server). That's for keeping tracking of all the changes and being able to give lost passwords to our customers if they lost it.
Mainly i want all the changes made to any account credentials (of any type) (including adding new accounts) to be sent to an email address.

Is there any way i can do this?

Thank you!

 

I know it can be a security issue but i'm beeing asked to do so.
I found something like a pasword trap writen in Perl (somewhere in this site) but no email sending and it only worked when the root user made the changes.

I'm shure dat this can be done with a code or something but i don't know how to do it.
If there is anyone that can help me, please do so.

Thank you!
