Hi,
We appear to be having some issues with some customers starting a day ago. They could be different customers, but we get the same response.
We go through mimecats to send and receive our email. I have checked some of their ip addresses for IP investigation, but they come back clean.
This is the bounce back;
---------------------------------------------------------------------------------------------------
This is a delivery failure notification message indicating that
an email you addressed to email address :
-- eddie.dougherty@lottechemical.co.uk
could not be delivered. The problem appears to be :
-- Recipient email server rejected the message
Additional information follows :
-- Message filtered. Refer to the Troubleshooting page at
http://www.symanteccloud.com/troubleshooting for more
information. (#5.7.1)
This condition occurred after 1 attempt(s) to deliver over
a period of 0 hour(s).
If you sent the email to multiple recipients, you will receive one
of these messages for each one which failed delivery, otherwise
they have been sent.
---------------------------------------------------------------------------------------------------
I have searched high and low for #5.7.1 and -- Recipient email server rejected the message, but cannot find anything.
The customers do not believe it is their end, but as the message states, its the recipients end.
Thank you for any help.
Regards.
Garry.
