If the message contains information that consists of material of a sexual nature that may only be viewed by an individual 18 years of age and older, the subject line of the message must include "ADV-ADULT" as the first characters.
For purposes of this subdivision, "commercial electronic mail message" does not include a message:
For purposes of this subdivision, "business relationship" means a prior or existing relationship formed between the initiator and the recipient, with or without an exchange of consideration, on the basis of an inquiry, application, purchase, or use by the recipient of or regarding products, information, or services offered by the initiator or an affiliate or agent of the initiator. For purposes of this paragraph, "affiliate" means a person that directly or indirectly controls, is controlled by, or is under common control with a specified person.
No electronic mail service provider may be held liable in an action by a recipient for any act voluntarily taken in good faith to block the receipt or transmission through its service of any commercial electronic mail message that the electronic mail service provider reasonably believes is, or will be, sent in violation of this section.
