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

# The mailman object is used for receiving (POP3) 
# and sending (SMTP) email.
mailman = chilkat2.MailMan()

# Set the POP3 server's hostname
mailman.MailHost = "pop.yourserver.com"

# Set the POP3 login/password.
mailman.PopUsername = "***"
mailman.PopPassword = "***"

# Copy the all email from the user's POP3 mailbox 
# into a bundle object.  The email remains on the server.
# CopyMail is a reasonable choice for POP3 maildrops that don't have too many
# emails. For larger mail drops, one might download emails one at a time..
# bundle is a CkEmailBundle
bundle = mailman.CopyMail()
if (mailman.LastMethodSuccess != True):
    print(mailman.LastErrorText)
    sys.exit()

# The directory path can be relative or absolute.
# This shows a Windows style directory path.  On other operating systems, the path
# would be different..

    # The OverwriteExisting property controls whether already-existing files
    # are automatically overwritten.  By default, it is set to True so that existing
    # files will be overwritten.

    # Setting OverwriteExisting = False will cause the attachment-saving methods to generate
    # unique filenames if a file with the same name already exists.  The actual filename(s)
    # saved will be present by calling GetAttachmentFilename for each attachment *after*
    # saving.
    # For example...
    email.OverwriteExisting = False
    success = email.SaveAllAttachments(dirPath)
    if (success != True):
        print(email.LastErrorText)
        sys.exit()

        # GetAttachmentFilename will return the new filename.

    # Attachments can also be saved individually.

        # If OverwriteExisting = True, the saved filename will always equal the original filename,
        # unless there are characters present in the filename that are not allowed by Windows,
        # such as * ? < > | etc.  In those cases the illegal characters are either removed or replaced
        # with underscore characters to allow the file to be saved.
        print("Saved Filename: " + email.GetAttachmentFilename(attachIndex))
        attachIndex = attachIndex + 1
