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.
