Hi team
Recently i have configured two smtp relay server on my environment. Both are running in server OS 2019 and both server are in same domain but in different location.
i am getting mail through one SMTP replay server and not through second smtp relay server. we have opened ports and checked in network part and there is no port blocked . i have reconfigure the server and still mails are in the bad mail folder.
Diagnostic-Code: smtp;553 #5.1.8 Domain of sender address <> does not exist
no idea where is the problem
