Which IPs are checked for spam?
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
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.
Thanks and cheers
Nicki

NO!!!!!!
trusted_networks is *NOT* a whitelist.
Please do not think that because a host is "trusted" it means it's spam
free. "trusted" means "part of my home network, and thus any mailservers in
it are relays I control". There's a VERY big difference here.
NEVER insert a host into trusted_networks unless it's a mailserver that you
control that never accepts email from a dialup node.
Please re-read my original message more carefully.

O.k. and via the trusted_networks I can whitelist some known server
not to check rbls against, right?
Because it would not be the best thing, if I'd have a customer
fetching his mail from e.g. hotmail and all mail ist tagged as spam,
just because hotmail ist on some rbl...
Cheers and thanks for the reply,
Nicki

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)
