Reason
Your e-mails have been rejected by our mail system because the information provided in the e-mail header does not comply with the specifications in RFC 5322 and RFC 2047.
The header field "From" is syntactically not correct.
Solution
Please make sure that the requirement of RFC 5322 chapter 3.4 for the header field "From" is fulfilled.
Example of syntactically correct notation:
From: "Sender name" <sender@example.com>
In case you use Non-ASCII characters like accented letters or symbols, please consider RFC 2047. For these characters you must use MIME encoding.
As soon as the corrections have been made by you, you can deliver emails to our system again.
