Sales invoices not emailing - Diagnostic code rejected
Hi All
In the last week I have started having emails bounce back from sales invoices that we have sent to customers saying - diagnostic code: rejected.
The process, and both sending and receiving emails have not been changed. Nothing has changed and we have been sending invoices to this customer for a long time. I have seen others have had this issue however it looks like they were all fix via private messages so I do not know what was done to fix the problem. If any one can help as soon as possible it would be appreciated. Thank you.
