Hello Albrecht,

I copied the header partly:

Content-Type: multipart/mixed;

        Content-Type: text/plain; charset=\"iso-8859-1\"

        Content-Type: message/rfc822
        Content-Disposition: attachment;

        Content-Type: multipart/related;
	 
\tboundary=\"_005_OF09C5FA2C95B6065FONC125881700424C2CC1258817004301DCbun_\";
        \ttype=\"multipart/alternative\"

        Content-Type: text/plain; charset=\"iso-8859-1\"

        Content-Type: text/html; charset=\"iso-8859-1\"

        Content-Type: image/png; name=\"ATT00001.png\"
        Content-Description: ATT00001.png

The company I work for part time uses MS Office and MS Exchange but I  
use Balsa from my home office. Hope the information above helps.
BR,

Are these two parts encapsulated in a multipart/mixed (“mixed parts”)  
or in a multipart/alternative (“alternative parts”)?  In the latter  
case, the content should actually be the same, according to RFC 2046,  
Sect. 5.1.4, but this requirement is sometimes violated, in particular  
by messages created by scripts (usually not by real MUA's)…

…quite often, (commercial, spam) messages are constructed as

multipart/alternative
    text/plain -> with a body reading “your MUA doesn't support HTML”  
or similar
    multipart/related
        text/html -> the real content…
        image/png -> …and some extra stuff referenced by the html

Printing such messages is currently broken in Balsa (see issue #75,  
item 3), working on that.

If my assumptions are completely wrong, it would be great if you could  
give more details (or even share the message).

Thanks, Albrecht.
