Sending 100k+ emails will most likely get smtp.ddd.com on a lot of blacklists.

At the minimum you need to throttle sending mails, and most likely you will also need to handle rejections properly.

You should also make sure that your SMTP server at smtp.dddd.com can handle 100k+ queued mails.

Personally, I would add provisions to restart the script from a given mail address. This involves sorting the list of mail addresses and then selecting all mails after the last (successful) mail.

Note also that you are (re)creating your $transport for every mail you try to send. You might want to do that outside of your mail subroutine instead.

Again, sending 100k+ mails sounds like a really bad idea and you should think about using one of the mail sender services like Amazon SQS or Mailchimp or whatever.
