I'm getting that same error here. telnet mx01.t-online.de 25 Trying 194.25.134.72... Connected to mx01.t-online.de. Escape character is '^]'. 554 IP=206.125.175.2 - A problem occurred. (Ask your postmaster for help or to contact t...@rx.t-online.de to clarify.) (BL) Connection closed by foreign host.
I'm calling it broken, not intentional. I put a notice up on my Spam Resource blog and Twitter. To all doing a telnet test (from a non-dynamic IP), is anyone NOT getting that 554 error?
