About the email delivery key:
To prevent or minimize spam mail, the delivery key string must be somewhere in the subject or anywhere in the first 500 characters of the body of the message, or it will be rejected by the mail server. Once we have received email from your address once, future email will be accepted for a period of time without requiring a key again. If you do not provide a key, the reject message you get back will also provide a key and instructions.
If you are a client, your email address[es] will be white listed permanently so that you never have to use the delivery key.
