Dear drupal users,
I have a site with some 1000 users which is now up for a very long time. I want to clean-up the user database and delete (or block) all users with an invalid email.
For this I thought about a script that connects to the mail server of the entered email address and check with a MAIL FROM/RCPT TO if the email address is valid. In case it is not, block or delete the user.
Before I now start to hack a little script for this, is there maybe already something available, I can use?
Thanks, Matthias
