Issue: When you send direct e-mail to several contacts, and some of those contacts do not have an e-mail address, the e-mail is sent to the parent account in stead. This is by design, but unwanted for some companies. For example: you would be e-mailing a company's CEO, while you expect to be e-mailing the employees themselves.

Solution: System Setting to turn off sending e-mail to the account when the contact has no e-mail address.

Outcome: No e-mail should be sent. Preferably a warning message "no e-mail address" should be shown.
