Repair MIME Formatting Problems in an Email

Demonstrates the Chilkat Email.ApplyFixups method, which repairs selected MIME-formatting problems commonly found in email produced by other software. The argument is a comma-separated list of fixup keywords. The currently defined keyword is FixRelated, which relocates HTML-related items (such as embedded images) into the appropriate MIME structure so they are not incorrectly presented as ordinary attachments. This example loads an email and applies that fixup.

Background: Not every mail program builds strictly correct MIME. A common defect is placing an inline image as a loose attachment instead of nesting it in a multipart/related enclosure, which makes it show up as a downloadable file rather than displaying in the HTML. ApplyFixups corrects such structural issues so the message renders as intended.
