On this special server the one and only client is the web application, where anonymous users can use a web form to ask for an account. They have to fill in their email address. The web application sends a mail to this address with a dynamically generated link the user has to follow to really make the web app create the account. In this scenario the "bad client" is "all the bored kids and bots" that fill web forms with senseless content, so the only way to fight this is using some kind of captchas, isn't it? I did not know that it's "no good reputation" for a sending mail server when this server often tries to send to non-existing email addresses... (So in theory, a "bad employee" could blame its companies outgoing mail server be generating thousands of mails to non existing email addresses?) Regards -stefan-
