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.

You don't fetch SPF records form port 80 do you?
