reverse_host_lookup with whitelist
We are finding in exim :
require verify = reverse_host_lookup
message = Your mail server IP address ($sender_host_address) has no reverse DNS PTR
in the custom_begin_check_message_pre section is very effective in fighting spam and wish to stick with it.
The one issue we are finding though is users of the system which have domains on the server are being rejected because they do not have a reverse dns setup with their ISP. How can I integrate a hostname or whitelist lookup to exempt the domain or IPs of the users?
Thank you!
