Hi,

I have installed Postfix and Dovecot on CentOS 7.

Emails can be sent from CentOS Mail CLI, Thunderbird and Outlook clients and deliver fine.

However, emails do not deliver to the Maildir of the individual users. All email is sent to the root account's mailbox.

I have created the maildir's. Changed the ownership and mode and even transferred the backup from a previous server.

If I move the email messages to the accounts using Webmin, they then delivered to the mail accounts.

PS: The MySQL database is acting up, after a user deleted the root account. I am not sure if this is related to the issue.

Thanks
