Say for instance you have some one trying to constantly access an <br class="">
account<br class="">
<br class="">
<br class="">
Has any of you made something creative like this:<br class="">
<br class="">
* configure that account to allow to login with any password<br class="">
* link that account to something like /dev/zero that generates infinite <br class="">
amount of messages<br class="">
(maybe send an archive of virusses?)<br class="">
* transferring TB's of data to this harassing client.<br class="">
<br class="">
I think it would be interesting to be able to do such a thing.<br class=""><br class=""></blockquote><div class=""><br class=""></div><div class="">Instead of being evil, just use fail2ban to address this problem :-) </div></div></div></div></blockquote></div><div class=""><br class=""></div>fail2ban is a good solution. I don't see any benefits in granting access to pop/imap as well.<div class="">On the other hand if you to this with smtp, your service is probably abused for sending spam</div><div class="">which you could use to train your spam filters :-)</div><div class=""><br class=""></div><div class="">Best regards</div><div class="">Gerald</div><div class=""><br class=""></div></body></html>
