Open letter to Earthlink

Mail from my list server (, ip to [your customer] is getting bounced with the message:

<[your customer]>: host[] said: 550 Dynamic IPs/open relays blocked. Contact <>. (in reply to MAIL FROM command)

And when I try to email the address that it says to contact, I get a further bounce:

<>: host[] said: 550 Unknown local part openrelay in <> (in reply to RCPT TO command)

First of all, I’m not an open relay. Never have been, never will be. And unlike you, when I have an error message say “Contact:”, I make sure the email address actually exists. Can you bozos please fix your open relay check, and fix your bounce messages?

  1. That’s not an “and”, it’s an or. It’s tough to get email out these days from an ip that was ever dynamic, even it it isn’t anymore.
