Here's some code which shows you how to use MimeWriter to build multipart
messages. The graphic is encoded in Base64.

regards

# Writes a multipart mail message: text plus associated graphic

f = open(mfile, "w")
# Create a MimeWriter
mail = MimeWriter.MimeWriter(f)
mail.addheader("From", "Steve Holden <sholden at holdenweb.com")

part1.write("This is a MIME-encoded message, with attachments. "
