I just skipped your question. Not sure, that I got it right.

DTML does not have true variables with assignments.
However, you can use the REQUEST object as a variable container.

If your problem is to collect all recipients from the form
and feed them to "sendmail" you could do something like this:

    <dtml-call "REQUEST.set(recipients,[])">
    <dtml-in "REQUEST.form.items()">
      ...
      <dtml-call "recipients.append(_['sequence-item'])">
      ...
    </dtml-in>

    <dtml-sendmail ...>
    To: <dtml-var "_.string.join(recipients,', ')>
    ....
    </dtml-sendmail>


You can even let ZPublisher form the list for you:

   give all form variables that will contain a recipient
   the name "recipients:list:ignore_empty"

Then, if at least one of these fields got a value,
you REQUEST will have a variable "recipients" containing
a list with all these fields.

I would like to point you to Python's "in" operator.
Instead of

    _['sequence-key'] == 'message') or 
    or (_['sequence-key'] == 'sender') or (_['sequence-key'] ==
    'senderEmail') or (_['sequence-key'] == 'subject')

you can write:

    _['sequence-key'] in ('message','sender','senderEmail','subject')

Easier to write and to read.
