[Zope] Iterating inside Sendmail

[Dylan Reinhardt]

This isn't a DTML problem, per se.  You can't send e-mail that isn't 
properly formatted... that's your core problem.

Unless the variable you render in the BCC field contains a value that 
conforms with RFC822, you won't get the results you're expecting.

Multi-line DTML statements insert line breaks into your output stream... 
that's not a problem when they're forming HTML, but it will mess up e-mail 
headers.  And when you're sending to multiple recipients (on any header), 
bear in mind that the correct format is comma delimited, not space delimited.

Try something like:

<dtml-call "REQUEST.set(my_names, [])">
<dtml-in "something_that_produces_addresses()" prefix=recipient>
   <dtml-call "my_names.append(recipient_item)">
</dtml-in>

and then in <dtml-sendmail ...>, put:

Bcc: <dtml-var "','.join(my_names)">

HTH,

Dylan
