keeping out hackers

I have 5 Classic ASP pages,

4 have just text and javascript in them.

1 has a script to generate an email automatically.

I wish to put this onto a server, but would like to know if it is secure (i.e. for hacking) - what should i have in my code to keep it tight?

If the email contains data entered in by the user you should probably check for an email injection attack.

Also post the code in the classic ASP section for it to be reviewed if you want :)
