tSendmail is limiting base64 string

Dear Talend Support guys,
I am trying to send an email via DI Component tSendMail. The email has to be a html one and there is an image inside as a base64 string.
When the email is sent by tSendmail the email client (Outlook) afterwards receives the email as html - so far so good.
However the base64 string is chopped to nearly its original half length. I have observed this if I save the email from outlook as html.
In contrast I did previously a System.out.println(<Mail-HTML-Content>) and there the base64 String is properly whole.
As a result of the chopped base64 string the image is not shown. :-(
What is going on there? Any ideas? By the way: Content-Type text/html and MimeTyp is also as HTML configured.
We are using Talend 5.3.1
Kind regards

Hi hilderich,
Have you tried this issue on latest build version 5.5.1? Does this issue repro?
Best regards
