The "dtml-mime" is supposed to set the "boundary" itself. It might be necessary to enhance this tag a bit in order to generate a "multipart/related" rather than a "multipart/mixed" "Content-Type".
As an alternative, you can use Pythons "email" package (part of Pythons standard library from Python 2.2 on, can be used for Python 2.1.3 as well) to construct the message and then send it via the "MailHost"'s "send" method. You will need an External Method for this (or allow import and use of the Email package for Python Scripts --> Zope Developer Guide).
Thanx for the hint. I was already looking at the email package to work arrond the lackings of dtml-mime. I just got suspicious because I found this in the MIMETools change-log: 1.11: "Added cid and cid_expr fields for the Content-ID header. This is needed for embedding images in a HTML message."
