The Email Archive uses plain text to format messages, even if their original format was HTML or rich text. If a message is sent in a format other than plain text, site participants can view it in its original format by clicking the link provided in the Email Archive message.
The Email Archive also uses links to handle attachments. Instead of receiving an attachment directly in the body of an email message, site participants can click a link to view the attachment. This feature helps prevent site participants from going over quota.
