Do you get this error at the connection or after you transmitted the
message?
It happens while connecting, so it's blocking on the IP address.
Even though I'm a tiny "provider" (4 users :), I've sent an e-mail to
postmas...@rx.t-online.de (note the "rx", which you need if you are being
blocked from contacting the usual postmas...@t-online.de address), to let
them know that their users will be missing a lot of e-mails (Germany is
quite "diverse" ISP-wise).
Maybe they'll reconsider (not because of my e-mail, but because of the flood
of complaints that should be — surely? — arriving :).
I've sent t...@rx.t-online.de an email and asked to clarify why my fullu
compliant mail server on TransIP network is being blocked and what kind
of problem has occured.
We'll see..
We'll see... I'd say this is a net neutrality issue. Have Germany
adopted some rules on net neutrality?
TBH I don't think this has anything to do with net neutrality, but the term is
(ab)used for many purposes and sometimes even with opposite meanings.
I think this is just Deutsche Telekom going Microsoft. But instead of rejecting
(or silently dropping after accepting) after DATA they block the connection
itself (so at least you know what hit you and when..)
To me it's a case of "their server, their rules" but also a clear case of
"shooting yourself in the foot" or if my German doesn't fail me now "sich ins
Knie schießen".
They'll learn..
