@Sam,
I'm sending mails by looping a csv file in Joomla. The first batch of about 120 emails were sent without a problem. The next batch of about 130 emails however didn't go anywhere. Seems the mails must have been blocked somewhere.How can I find out exactly where and how can this be prevented? Is it possible to send mails in a loop without a problem?--
