The prefix attribute of the <dtml-in> tag renames the sequence-specific variables within the loop. Thus: <dtml-in some_list> <dtml-var sequence-index> : <dtml-var sequence-item><BR> </dtml-in> produces the same thing as: <dtml-in some_list prefix=list> <dtml-var list_index> : <dtml-var list_item><BR> </dtml-in> The second form substitutes list_index for sequence-index, list_item for sequence-item, etc. The prefix attribute isn't required for a simple loop, but should (IMO) be considered a best practice. It becomes *necessary* when you nest loops or want to make use of a sequence variable in an expression... in those cases, you'll be glad you're in the habit of using prefix and don't have to figure out why <dtml-var "do_something(sequence-item)"> is unable to bind the name "sequence". (In an expression, "sequence-item" means "the sequence variable minus the item variable" not "the variable called sequence-item") For more info, see the docs for dtml-in.

Thanks Dylan,
I have to run to a meeting tonight so I'll have to write back later to let you know how it goes. I understand the first call, I'm making an empty list. then I'm bringing the Catalog in and appending the email addresses to the list. The part I'm not sure about is the "prefix=recipient" and (recipient_item). Everything else seems to make sense. The dtml-var makes the list into a string that is comma delimited. Thanks for the info, at least I know what the issue is now.

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)">

Thanks Tino,
I guess this is where dtml just doesn't cut it. i'm real new to Python, (just learning it), so I'll try working on this for a while and see if it does it or not. I am just confused as to why dtml-in does not work inside of sendmail. I also tried, as Mike suggested, creating another method and moving the [with / in] statement to it and then calling it as Bcc: <dtml-var listNames> and that didn't work either. When I 'viewed' it, it appeared to work fine, ie: email@address1.com email@address2.com email@address.com etc. but not inside of sendmail.

Hi Michael,
just drop DTML for this too and use Mailhost.send() instead. If you have a recent Zope, it strips BCC automatically and you only have to provide it with mailtxt, which is mailheader + 1 free line + mailbody. Minimal mailheader is To: Person <person@target.com> From: Person <person@source.com> Subject: what to say...
The simplest way to do this in a loop is to use a Python long string:
msg="""To: %(to)s From: %(from)s Subject: Your subject
Hi there, foobar... """.replace('\n','\r\n')
The replace stepp changes the line endings from single newline (Unix, python) to carriage-return + newline, which is for rfc822 complience.
all_addresses=[{'to':'Person1 <person1@person1.com>,'from':'Me <myself@me.com>'}, {'to':'Person2 <person2@person2.com>,'from':'Me <myself@me.com>'}, {'to':'Person1 <person3@person3.com>,'from':'Me <myself@me.com>'}]
for target in all_addresses: Mailhost.send(msg % target)
This is untested, but schould give you a starting point.
Does this help?

I have put up a small job site for Linux jobs here in N. Colorado. I want to offer the option of entering an email address and have job postings emailed directly to subscribers as they are posted. I tried the example below, but there seems to be a problem iterating inside sendmail.
For the time being, I just created a method and manually entered all the email addresses in it, ie: Bcc: <dtml-var listNames>, but I would like to automate it if possible. Does anyone have any idea on how to approach this?
