I'm looking for a a web bulk mailing sw. It should be used not for spam, obviuously. It should be used for an association to deliver newsletter to certain member groups.
It's not exactly what you asked for, but ezmlm is a nice mailing list package.
It has automated subscribe/unsubscribe, automatically unsubscribes email addresses that bounce, and it can be configured with QmailAdmin.
You can import/export lists of addresses from the command line, and can make lists moderated so only you can send to them.
