Hi Steven
Checked our Outbound Mail Route and this is configured to use 'Direct Outbound (recommended)' This is set on our own Ourbound Mail Route 'countydurhamhousinggroup.co.uk' as this is the one we use. But I did note this was not set on the live.hornbill.com outbound mail route. Or does it need to be set here aswell ( for live.hornbill.com)
