For my fellow mail server administrators: * 205.201.128.0/20 * 198.2.128.0/18 * 148.105.0.0/16 Those are the ranges you'll want to add to your blacklists.

- DKnoll 9y agoBlacklisting would be pretty irresponsible, greylisting maybe.
- jlgaddis 9y agoOn my servers, they are already greylisted (almost everyone is, by default). Greylisting works very well against most spammers, hijacked PCs, etc. (I use "spamd" [0] from OpenBSD, which also makes blacklisting very easy, FWIW). In MailChimp's case, the only thing that greylisting would accomplish is delaying the amount of time I wait to get their spam^We-mails.

- DKnoll 9y agoWrong terminology, my bad. I meant adding a rule for MailChimp origin emails that increases spam score but doesn't necessarily doom the message alone. Dropping their mail altogether would definitely cause some legitimate messages to be lost.
