There are a couple of really important things to consider with email.
1. It is a very dangerous pathway for various kinds of computer viruses etc., so be really careful opening attachments and educate yourself on good security practices and things to watch out for.
2. When there is a problem, IT people often need more detail, but we don't need the content of email conversations. We sometimes need the email header information or the error message email if their is some sort of an automated error email.
