To protect your email addresses from spammers and cyber bots harvesters all you need to do is the following:
If you put addresses in the BCC field of an email it will be secretly copied to those addresses, and none of the other addresses in the To, CC, or BCC fields will know about it because the BCC field is not displayed on incoming messages.
Example:
To: John Smith
CC: <==Do not use this field
BC: frank@karateka.com, Chandranerd@hotmail.com, etc
When the recipient receives the email, it won't see the BLIND COPY email addresses
