Embedded Images Stripped By Receiving Clients

mikebabb[ at ]cableaz.com 4/26/2006 9:30:33 PM

I'm embedding images into HTML emails using Redemption and following
the example given here:

http://www.dimastr.com/redemption/

The emails appear to get created and sent fine, but the images get
stripped when received by Outlook Express and get treated as
attachments when received by a Yahoo account. It appears to be part of
the client's virus protection. Does anyone have any idea what I can do
to prevent this? Thanks.

Did you look at the message source in OE (RMB | Properties | Details |
Message Source)? Arew attachments there? Are they referenced Ok by the HTML
body? Do attachment content-ids look Ok?

The attachments aren't there in OE. Also, the img tags have been
removed from the source.

So the message gets modified by the mail server, right? Can you send
messages with the embedded images through the Outlook UI to teh same
address?

Yes and Yes.

So what is different between messages created by your code and by Outlook?

Here is the message I'm sending that doesn't work:

<HTML><head><meta content="TX_HTML32 12.0.230.500"

Here is the equivalent message generated by a different source that
does work:

<P><SPAN style="FONT-SIZE: 10pt"></SPAN></P>
<P><SPAN style="FONT-SIZE: 10pt"></SPAN> </P></BODY></HTML>

There are differences, but none that I can see that would cause the
problem.

Can you try to set *exactly* the same HTML?

I've reduced the HTML body to the simplest form possible:

<IMG src=cid:image1>

and still the image gets stripped. I'm setting the following
properties on the attachment:

attachment.set_Fields(0x370E001E /*content
type*/, "image/jpeg");
attachment.set_Fields(0x3712001E
/*PR_ATTACH_CONTENT_ID*/, "image1");

is there any other property that should be set?

Did you try to make the attachment contents id value the same as the one
used by Outlook?
Did you compare the two messages in the Sent Items folder with OutlookSpy or
MFCMAPI?

The only real difference I see is the value of the
PR_RENDERING_POSITION. It's -1 for the one that works and 1 for the
one that doesn't.

Re: Embedded Images Stripped By Receiving Clients

"Dmitry Streblechenko" <dmitry[ at ]dimastr.com> 5/8/2006 5:14:37 PM

Did you try to specify the attachment positon open calling Attachments.Add?
What is your code?

I'm not sure what you're asking. Here is my code:

Redemption.Attachment attachment =
safeMailItem.Attachments.Add("c:\\showletter.bmp",
OlAttachmentType.olByValue, 1, "image1");

Re: Embedded Images Stripped By Receiving Clients

"Dmitry Streblechenko" <dmitry[ at ]dimastr.com> 5/8/2006 8:58:42 PM

Your code explicitly passes 1.
In this case you'd be better off only specifying the very first parameter
(file name) and passing empty variant for the rest of the parameters.

I guess the equivalent of empty variant in C# would be null, so I
passed that in for the last three parameters and saw no change.

Save both good (sent by Outlook) and bad (sent by your code) mesasges as MSG
files (File | Save As), zip them (important!!!) and send to my private
address.
