Sending email with multiple binary attachments using BTS 2006

[zee]

I'm trying to send an email with multiple attachments from an orchestration
using a SMTP port in BTS 2006 using custom pipeline component with MIME
encoder. I got it to work where I get an email with multiple attachments but
the attachment data is corrupted for binary attachments (.exe or .doc etc).
The orchestration calls custom .Net code which creates and populates the
multiple parts with the attachment data. Here is the code snippet for
reference:

byte[] databytes = System.IO.File.ReadAllBytes(@"C:\notepad.exe");
MainMessage.AddPart(databytes, "Attachment1");
Microsoft.XLANGs.BaseTypes.XLANGPart part1 = message["Attachment1"];
part1.SetPartProperty(typeof(MIME.FileName), "t2.exe");

How can I get the binary attachments to work without them getting corrupt?
Any help on this would be appreciated.

Hi,

Which type of content transfer encoding is used on the MIME/SMIME pipeline
component? Is it the default Base64? I think you should try attaching the
files directly(using Attachments property) instead of adding them as
message parts. Some information/reference may be helpful:

Also you may set 'Send body part as attachment' to true to have a try.

Thankyou for responding to my question and providing the useful links.

The encoding in use is the default base64 encoding on the pipeline. It seems
that BizTalk is sending the message part out as an XML as the attachment I
get in the email looks like this:

<?xml version="1.0"?>
<base64>0M8R4KGxGuEAAAAAAAAAAAA</base64>

How to indicate to BizTalk to treat the message part as a MIME message part
and not a XML message part? I'm sure it would work if I use the Attachments
property of the SMTP adapter, but I'm curious to know why it doesn't work
this way.

Any comments/suggestions would be appreciated.

Hi Zee,

I'd perform some further researching on how to make it work with message
parts. Please wait for my update. Thanks.
