Some of us might have been DDOSed from making posts on this list. my email address points right back to my web server..... What does everybody else think? There are some mailing list archive websites that goes to the website derived from your email address domain and links the favicon (if any) for display next to your posts. Whether that is enough to lead to a DOS is debatable.
It might also query SPF records. That could lead to server load as well, as could anything else that 'leads to your server'. But I doubt that a favicon, even if requested by 1000 clients going over the archives in an hour, would cause heavy enough traffic to DDoS a serious webserver.
