This mail log shows an attempt to send email to the address "mailuser01@ramya.com".
"ramya.com" appears to be configured as a local, or a locally-hosted domain, however no such mailbox exist, and, as such, the mail gets returned as undeliverable. However, "root@ramya.com" is also undeliverable, so is "postmaster@ramya.com", because none of these mailboxs exist.
Sounds like a local domain misconfiguration.
