Ken, you really need to read the SMTP RFCs before referring to them in order to claim that other people are spreading “misinformation”, when in fact that is precisely what you are doing. In section 4.1.4. of RFC2821 it says the exact opposite to your statement “By not providing correctly resolving DNS, and mismatched server names, they break SMTP RFC’s.” :-

An SMTP server MAY verify that the domain name parameter in the EHLO
command actually corresponds to the IP address of the client.
However, the server MUST NOT refuse to accept a message for this
reason if the verification fails: the information about verification
failure is for logging and tracing only.

Therefore it is earthlink who are guilty of breaking the RFC, not dreamhost. It could be argued that since spam is so much more common now than in April 2001 when RFC2821 was published, that RFC2821 is out of touch with the times and should be changed. Certainly earthlink are one of many who deliberately choose to break it in this manner. Though all this is probably moot now since it is 18 months since the problem was described.

So I still can’t see wher any of this was resolved? Will I never be able to send emails to Earthlink customers as long as I use my current provider?

I have a personal site hosted with dreamhost, but also designed and run the infrastructure of another Atlanta-based hosting/email provider. A day and a half ago that provider was also blacklisted by Earthlink. I want to thank everyone for posting as I’m using the lessons learned here to [hopefully] speed up the unblocking process. Reading the blog, I really HAVE to point out one glaring problem with DH. From a previous post:

This is COMPLETE and TOTAL crap. Total snowjob hoping nobody here understands clustering. It’s not a misunderstanding. It’s a misconfiguration on DH’s side. By not providing correctly resolving DNS, and mismatched server names, they break SMTP RFC’s. I too run a load balanced, firewalled mail cluster and have none of these problems. We were blocked by Earthlink because one malicious customer sent out a mass mailing from his home with a return address hosted on our mail servers.

Sorry. Got a little peeved there for a second. I really hate misinformation .. and Earthlink’s cost-cutting
