(Ruby) Insert Email into GMail Folder

Directly inserts a message into only this user's mailbox similar to IMAP APPEND, bypassing most scanning and classification. Does not send a message.

This example will create a Chilkat Email object and upload/insert it into GMail. Then adds the "INBOX" label to the email to make it appear in INBOX

Chilkat Ruby Downloads install from rubygems.org gem install chilkat or download... Ruby Library for Windows, MacOS, Linux, Alpine Linux

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

# Upload to GMail (does not send, but just inserts).

# IMPORTANT: After uploading/inserting, you won't see the message in the Inbox.
# In your web browser, if you go to "All Mail", you will see it.
