I'm so sick of shit from Yahoo. It's bad enough that free email providers are spam-havens, but yahoo doesn't even ACCEPT spam/abuse reports any more. You can only report spam if you are a yahoo user and get spam to your account. If you're a regular old mail server admin, you just have to grin and bear it. Today was the finally straw. I got a notification that I was added to a yahoo group, followed by a slew of non-english crap emails from that group.

**** Yahoo.
So I'm going to blacklist the whole company. But how can I find out what IP ranges they use for their outgoing mail servers? I tried googling it but it's ungooglable because there are just too many people asking the opposite question, what to do when yahoo is blacklisting YOU. Answer: Thank the internet gods were blessed with that luck.

You don't have to.

Postfix check_sender_access + regular expression matching on the hostname.

Here's a list that's 2.5 years old, but the thread is active so I'd guess it's still up to date.

Blacklisting the world's biggest email provider is not a good idea anyway.

You should at least have the courtesy to auto-respond to any incoming Yahoo message with something like.

"Sorry, I don't want to read your shit. Rot in /dev/null." or something.

Blacklisting the worlds biggest email provider that doesn't let you report spam from it's system, IS a good idea. In fact it's a great idea, and more mail server admins should do it. Realtime blacklists should add yahoo's servers to their lists. If you're not even going to try to stop spam, then I don't want you connecting to my server.
