I have had a .com domain with Dynadot with email forwarding for ~3 years with no problems, however for the last couple of days I have not received any emails sent to addresses on this domain.
Emails sent directly to my ISP domain are received with no problems so the issue is not at my ISP's end.
I have checked the forwarding settings againt my domain and all appears to be in order.
We just got the trace back form engineering and it does that messages are successfully reaching the internode email server where they are being labeled abuse and bouncing back to us.
Can you please forward the traces that show this happening as my ISP (who also hosts the email server) say that they can't see anything unusual from their end.
While we can't provide you with trace, our engineers believe they can work with Amazon to address the problem directly. It is being worked on now. Please give us about a week to get it straightened out. In the meantime, can you create a free email address to receive your forwards? Something like gmail or hotmail perhaps.
I'll look into this further but, the way I understand it is, our system will attempt delivery 3 times before discarding the message. Once discarded, the message is lost and can not be retrieved or redirected.
