Hello Remy,

this is the (faulty) test-attachment (the correct end would be: ..Ende!): 

TESTMAIL

testmail attachment
���___�___���
<><><>1234567890
Ende! �y+l�]�ƾz�wj�


The ���.. in the middle are the German "Umlaute".

I figured something out. Your example works, because
you use:
          attach1->ContentType = "text/plain";

With      attach1->ContentType = "multipart/application";
or        "multipart/mixed"
you get the "additional bytes problem" with the .txt-file and
with other, e.g. .pdf-files.

It looks as the problem is caused by the "multipart" phrase.
Even when you use "mime/image" or "mim/image" or just "image" it'ok...

I have not tried "attach1->ContentType = "text/plain"; " before,
because i wanted to attach also binary files (attachment.txt was just one example), but surprisingly these work also with
"text/plain" .


What would be the CORRECT ContentType for binary attachments?


Thank you for your valuable tips, also the free .. delete subject.
Everything would be much easier for the C++ users
like me if there were a few short examples of these components.
If there is something to find in the documentation, ist a 
listing of classes, methods, functions and properties, but the more conceptual overview of HOW to use a special component is missing.

Regards Robert
