From an OCI compute VM unable to send message using mailx

Content

Hello- I'm logged into an OCI compute instance, and trying to send a test message to my corporate email account as follows:

mailx -s "Hello World" nagendra.solanky@oracle.com  < out.txt

It doesn't work, and I find no issues in syslog or mail mail.

However, email to my yahoo account works just fine.

mailx -s "Hello World" nsolanky@yahoo.com  < out.txt

 

PS: I'M NOT USING EMAIL DELIVER service.
