Are you doing anything to prevent illegal or abusive use of CustomMailer?
Yes. First, the CustomMailer license explicitly prohibits any unethical or illegal use, and we take this obligation seriously. When we contemplated adding higher performance features to CustomMailer such as multi-threaded sending, we worried about the increased potential for use of CustomMailer for illegal or abusive email practices. For this reason, we decided to add the following “unforgeable ID” feature to CustomMailer. Every email sent out by most standard email programs (Outlook, Netscape, Eudora, etc.) includes a special mail header field called “X-Mailer”. The X-Mailer field is used to identify the email program that sent it, and is seen by recipients if they turn on “full” headers in their email reader. In its X-Mailer field, CustomMailer includes 6 encoded digits that uniquely identify the particular CustomMailer installation. This has two important consequences. One is that recipients can if necessary build filters to identify and screen out all email sent by an abusive party
