I am trying to whitelist only mailchimp's servers with /etc/exim4/local_sender_blacklist. I know it is effective because I am using it also to whitelist a few domains, here is what I have: https://pastee.org/9vvxq, but mail is still being rejected by exim with the message: https://pastee.org/e7uk8 (redactions mine).
Any idea what could be wrong?
The IP given in the log is within the range in the config
I got the ranges from here: http://mailchimp.com/about/ips/
