I have got a RSS feed running using a cronjob which calls in blogs posts from one site into another, however on the site I am calling in the posts too I am receiving an error on the front saying:
SMTP Error! The following recipients failed: email@example.com: (http://www.datapathltd.com) [184.108.40.206]:33794 is currently not permitted to relay through this server. Perhaps you have not logged into the pop/imap server in the last 30 minutes or do not have SMTP Authentication turned on in your email client.
What is causing this and how can I change the recipient email address as I can not find this anywhere?
