# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# Use TLS

# We can choose to fetch UIDs or sequence numbers.
fetchUids = True

# Fetch messages from the mailbox using a search criteria.
# This example finds NEW emails: these are emails that have the RECENT flag set, but not the SEEN flag:
# messageSet is a CkMessageSet

# This example will download headers, and then download
# the full email for those emails sent from a contact
# in our database.

# When downloading headers, each email object contains
# (obviously) the headers, but the body will be missing.
# Also, attachments will not be included.  However, it is
# possible to get information about the attachments
# as well as the complete size of the email.

# bundle is a CkEmailBundle
bundle = imap.FetchHeaders(messageSet)

    # The sender's email address and name are available
    # in the From, FromAddress, and FromName properties.
    # If the sender is "Chilkat Support <support@chilkatsoft.com",
    # then the From property will hold the entire string.
    # the FromName property contains"Chilkat Support",

    # Assume at this point your code checks to see if the sender
    # is one in your contacts database.  If so, this is
    # the code you would write to download the entire
    # email and save it to a file.

    # The ckx-imap-uid header field is added when
    # headers are downloaded.  This makes it possible
    # to get the UID from the email object.
    uidStr = email.GetHeaderField("ckx-imap-uid")

        # generate a unique filename...
