Postfix Error: cannot update mailbox /var/mail/user for user user. error writing message: File too large
Earlier while troubleshooting an error with PHP’s mail function I noticed an error in the maillog on a CentOS server. I know I have run into this error before and previously I fixed the issue by setting a larger size limit on the Postfix mailboxes. Below is information about the Postfix error in the maillog explaining mail cannot be delivered to a specific user because the mailbox has reached the maximum size allowed as configured in the Postfix main.cf file.
