Maybe security polices, data protection act, control of sensitive data - and maybe finish on the reasons why it's a bad idea to email anything your not supposed to. You have to look at it from an employers point of view, it could easily be confidential information your sending out, peoples salaries, contact information, company credit card details. If you got paid for it, then there's no way it was worth it.
I'd be really concerned if I was you, with this on your record there's no way any IT department would employ you. If you really want to work in IT, I suggest taking a sideways approach, find a job that could expand into purely IT but won't require IT specific references. The most important thing though is to stop talking about it, you tell someone now, they join the company you work for in a few years, then they accidentally mention what you did.
I had a friend who got a job setting up a database in a small company, and he was pretty well geared up to be the database admin at the end of it - so he asked me for some advice on how to ensure that would happen. So I told him to make the system complex enough to rely on him, and he did just that... He set a user level password then went on holiday for a week without telling anyone the password!. Needless to say he got fired, and has never worked in IT since. There's a lot of skills involved in IT, beyond what you can do with a computer and these skills are never taught (often because IT teachers tend not to need them).
