[Zope-CMF] mass mailings

[Chad Nantais]

I want to send a weekly email newsletter out to all members of my CMF site 
(could be up to 2000 users). I plan to create a script that gets a list of 
all member email addresses from memberdata and inserts that into the 'To:' 
line of an email that will be sent using my smtp mailhost. However, I don't 
want the recipients' addresses to be exposed to the recipients. 

1. How can I keep the list of recipents undisclosed in the email.
2. Is mailhost a bad way to do mass mailings?
