Re: Can't send emails as of today. Is Virgin using other servers now?
I have been using an old Exchange server to handle my email for about 15 years. It has been working all that time using the smtp.blueyonder.co.uk smart host
However for the last couple of days I have been getting the following message and my outbound mail is not being sent (I have not changed anything on my Exchange server):
"
Delivery has failed to these recipients or distribution lists:
[EMAIL ADDRESS REDACTED]
This message was rejected by the recipient's e-mail system. Microsoft Exchange will not try to redeliver this message for you. Please check the recipient's e-mail address and try resending this message, or provide the following diagnostic text to your system administrator.
The following organization rejected your message: csmtp3-prd-nl1-vmo.edge.unified.services.
"
Does anyone have any thoughts why this has started happening?
