A method for prohibiting email content propagation that receives, at a server, an email message. At the server, at least one email address associated with the email message which is designated not to receive a content of the email message is identified. At the server, the email message is modified by selectively removing a content of the email message to be conveyed to the at least one email address. The server conveys the modified email message to the at least one email address. The server conveys the email message to one or more recipient email addresses except the at least one email address. Consequently, the server has sent a submitted message to multiple email addresses, while modifying the content sent to a subset of the addresses that received the email message.
