220 T-Online ESMTP receiver ready.
QUIT
221-2.0.0 mailin82.aul.t-online.de closing.
221 2.0.0 Closing.
Connection closed by foreign host.
From same data center but a real email server cluster..
Looks like they might be using aggressive RBL checks, but exempting

Also, try from servers with 'mail' in the PTR record.. just a theory
