Copying email to another user

Hi folks,

I've decided it's about time to introduce my nine year old daughter to the world of email. I've got her an account at our ISP, and I have set it up so:

1. It's pulled down from the ISP by fetchmail;
2. It's filtered for spam;
3. It's delivered to my inbox, where I filter it for spam and perverts;
4. I bounce it on to her (I've set her up to use KMail)

The idea is that I want to be able to teach her to use the technology properly and safely. The very little email she currently receives comes directly to my account, but I think it's time for her to get a little more independence. This method allows me to protect her from any spam that gets through and potential predators until she's more able to do this for herself.

Anyway, I want to be able to keep an eye on what she's sending out as well. I think it's important to be able to see what sort of information she's giving out. KMail adds her full email address to the message and passes it on to exim for sending into the world. This makes things really tidy, except it gives me no way of seeing what she's sending. I could probably set KMail up to bcc: me in on everything she sends, but I want to encourage her to play around with the preferences and settings, and I don't want her to break my set up.)

Does anyone know how I can configure exim to copy me in on whatever she's sending?

(IN CASE YOU WERE THINKING: Yes, I am aware that she could circumvent this whole setup. Apart from the potential holes in my system there's nothing stopping her from getting herself a secret gmail account. She's not there yet -- I give her twelve months before she gets to the 'Hey! Dad's so dumb he doesn't even realise...' stage. When she does get there I'd like to think I taught her something about online safety!)
