How does MailSteward handle attachments?
Attachments are stored in their original binary format. When an email is displayed, the attachments are listed as links at the bottom of the email. Clicking on a link gives you the option of either saving the attachment as a file or launching it with the default application, so, for example, if you click on a jpeg graphic attachment, it will launch Preview to display it, or whatever you have the default application set to for jpegs. You can choose not to archive attachments, and you can delete attachments that have been archived.
