[exim] skipping log, host based.

Hi !

We have a loadbalancer in our network which checks if our mx'es are
alive every 10s. But these 'checks' generate a 'SMTP protocol
error'. Disabling of 'smtp prolocol errors' globaly is no option for
statistical reasons.

Is there any way to skip logging for 'these hosts' (the balancer) ?

bye,
Chris
