There is: smtp_accept_max_nonmail

<http://www.exim.org/exim-html-current/doc/html/spec_html/ch45.html>

It's not explicitly for this case, but would catch "a mad client looping 
sending EHLO, for example." You can limit the hosts to which it applies 
with smtp_accept_max_nonmail_hosts

It should be on by default, set to permit 10
