The mail queue using throttling works really well. I can send out a batch of emails over 2 or 3 days. Is it possible to stop the emails that are still waiting and appear as not sent in the email queue log? I am pretty sure the answer will be no, as I imagine it is in the hands of the cron job. Thought I'd ask though. Could be useful if you suddenly realise you have made an error in the email. Thanks.
