Note that when I set the body exchange in MimeMultipartDataFormat.java <https://github.com/apache/camel/blob/main/components/camel-mail/src/main/java/org/apache/camel/dataformat/mime/multipart/MimeMultipartDataFormat.java> directly it works:
ByteArrayOutputStream byteStream = new ByteArrayOutputStream(); mm.writeTo(byteStream, headers.toArray(new String[0])); exchange.getIn().setBody(byteStream.toString()); however when using the normal stream: mm.writeTo(stream, headers.toArray(new String[0])); (on line 167) On Fri, Feb 14, 2025 at 5:02 PM ski n <raymondmees...@gmail.com> wrote: > I have the following route: > > <route> > <from uri="direct:start"/> > <enrich strategyRef="CurrentEnrichStrategy"> > <simple>direct:enrich</simple> > </enrich> > <marshal ref="mimemultipart"/> > <to uri="log:loggingmimemessage"/> > </route> > > This route works as follows: > > 1.
