[exim] multiple external clamd servers

Hi All,

I have to external servers running clamd and my ac_scanner option on my 
mail server looks like that:
av_scanner = clamd: IP1.X.X.X 3310 : \
                                         IP2.X.X.X. 3310

which I would expect to provide some load balancing between the two
clamd's as it happens for example in the case of having 2 external spamd
servers
and a spamd options like the following:

spamd_address = IP1.X.X.X 783 : \
                                      IP2.X.X.X. 783

Is any using a similar set up and managed to get load balancing between
the external clamd's?

thanks
