Hi everybody,

I am really hoping on a quick answer here, I have a crazy deadline in a few days, so sorry for barging in like this...

The problem is as follows, i am to send an email with a (hidden) plaintext part, an html part and a few embedded images. This went pretty smoothly while testing it on Outlook Express, but when I looked at Yahoo and hotmail, the images show up as attachments and are not displayed inline, inside the html.
The last two days I have been trying to get it to work, by trying hundreds (really!) of combinations, i.e. different ways of combining the related and alternative multiparts and their bodyparts ; by adding and removing and setting the headers of the individual bodytParts programmatically ; comparing the raw source of my emails and other (3d party) emails that do work on Yahoo & Hotmail, etc, etc.

No luck so far and time is running out

Below you can find the source of my mail composition class, please have a look at it and tell me where I am messing up. Sorry if the code is messy (all those commented-out lines) but this is really work under construction.

Thanks a lot,
Rob Boellaard
