We are currently experiencing some problems for customers sending or forwarding email to @btinternet.com email addresses. These messages are being deferred with an error ’421 Too many messages (220.127.116.11)’
This appears to be due to a BT policy and outwith our control. We recommend affected customers contact BT to ask them to review the policy, as there is nothing we are able to do about it from this end.
BT’s contact details can be found here - http://home.bt.com/pages/static/i/pansegment/contact_us/contactus.html
