now some accounts can read these email addresses inwhich isn't intentional

A former client (errantly) blamed his ISP for spam. So he changed ISP's and notified everyone in his address book of the email change . . . and in doing so, sent out the email addresses of everyone in his address book, revealing all those addresses to everyone on the list. So he can expect the spam to return in a very short time to his new address, whatever "hole" it was getting in before will reappear.
If I were unscrupulous, I could start my own spam service with the number of clients that have sent me their entire address book. :-D
This is a common problem: people use their mail interface to forward emails to everyone in their address book and don't know they are revealing those addresses to all the recipients. When you use an address book to send, you really have to look closely - the BCC field is NOT the first option in most of them, you have to look for it.
When you bcc an email, the addresses in the list are NOT included in the headers of the email. That which does not exist cannot be read. I just checked an email sent from a form mail program (that I wrote). It sends the mail to a business account and bccs the mail to a personal account. The personal account information does not exist in the source code of the mail.
If bcc addresses are being added to mail headers, this is a bug.
