Hi, we are using multidrop in some installations. Now I was asked which IPs of the received headers are checked against the rbl. As I found nothing in the faqs I hope someone can answer me this without having to search through the source.
For most RBLs, *ALL* IP addresses are checked.
For Dialup lists, only the IPs dropping off email to a host listed in trusted_networks will be checked. (note: SA tries to auto-detect a sensible trusted_networks if you've not set one manually, but it's hardly perfect and often gets confused if you have NATed mailservers)
