I don't know of a mod, but I have a suggestion: create a usergroup for users to be deleted. Then use a query to move users to that group, like maybe:

UPDATE user SET usergroupid=X WHERE usergroupid=4 AND email LIKE %hotmail.com%

(usergroupid=4 means users awaiting moderation). You'd replace the X with the usergroupid you created. You can do this multiple times if you have more than one email provider you want to exclude.

Then use Move/Prune users to delete users in usergroupid X.

The safe thing to do would be to have a backup before making any changes directly to the database.
