550 Blocked for sending broken messages

[owindrich]

Hello,

For some reason only one provider does't accept our email anymore.
Everybody else does, gmail, hotmail and all others, but not our
local cable-company.

I can't find out why? On others DA servers it works
Is there a way to fix it within DA or within the OS?
It was a clean install Running CentOS with ESMTP Exim 4.67

Below is the message I get when I try to send a mail with webmail.

Not unless they'll tell you what they mean by broken messages.

Problem found

Problem found, they blocked the sender domain and finaly confirmed that its was blocked on there site.

A previous newsletter that was send under that domain had multiply header info lines that caused this block. It had nothing to do with the main webserver settings, but with the email-newsletter php scripts on that domain.

At the start of this problem they said that it was the way we send out the current email messages, and that there was "no block" for that domain.

We finaly we found the real problem, they have to unblock it, and our problem is solved then.
