email addresses

Linux and Unix-Like UNIX and Linux Applications

Greetings to all.
I have installed dadamail on my web site and it works extremely well.
I have two questions:

  1. I have modified dada to bounce bad emails, but only the first newsletter will use the modifications. If I create another list, it doesn't use the modification.
    What gives?

  2. Are the email addresses stored in the newsletter user list safe from email harvester robots?

I deeply appreciate any help.
