Postfix Error: cannot update mailbox /var/mail/root for user root. cannot create file exclusively: No such file or directory
While working on a project unrelated to Postfix on a CentOS server I noticed an error in the mail logs that indicated an issue with the root users mailbox. I have yet to locate the root cause of the problem however I was able to resolve the problem easily. Below I explain the error in more detail as well as how I was able to resolve the problem with sending email to the root users inbox.
