Hi, we have a user complaining about receiving email from a solar panel company and want us to block it. The problem is that it originates from mailchimp, which is whitelisted.
It's my belief that mailchimp is safe to whitelist (mcsv.net). However, what happens when an email is received that needs to be blocked? Do you just report it? Chances are probably good that I could click the "unsubscribe" link and just unsubscribe the user, and will probably do that, but I'm looking for a more general solution. I'll also report the sender to mailchimp, but the email looks like they're following all the rules. The sender is exped...@iowawindandsolar.com. Should I block the From address in postfix? Is it possible to blacklist the From when the sender is whitelisted?
