Unreachable SFC-CNS E-mail Error (Mar. 31)
Lately, we received some requests about the following troubleshooting;
- Not delivered emails which users sent via the SFC-CNS SMTP server
- Delayed email receiving via the SFC-CNS IMAP server
We have found that IP addresses of SFC-CNS SMTP servers are registered to Real-time Blackhole List (RBL) in any security appliances and applications. We have already identified causes and applied for deleting the IP addresses in RBL.
Affected destinations are:
- hotmail.co.jp
If you have not sent or received SFC-CNS emails yet, please contact us.
Thank you for your patience and understanding.
