Hello, There is a problem with sending emails from employees in @cisco.com domain to some certain domain. Emails in opposite direction pass without problem. No errors, no warnings or any other logs at cisco's employees desktop.. We checked popular rbls, spamhauses, senderbase etc. Other domains on the same MX cluster receive emails from @cisco.com without any problems..
I try to get help in many ways ( cisco tac, a few account managers, channel partners) but without success.. If you need any details about "certain domain" etc, let me know, please. I can send as private mesaage my business contact. Big thanks for contact or any other advice best regards, Peter
