Maildir and MBOX are just the file formats to store email messages to a local system. Earlier, MBOX was used as a format to store emails on a cPanel server; but currently, Maildir is mostly preferred. In MBOX format, messages are stored in the same file on the server. Whereas Maildir stores messages in a tree form with unique names on individual files.
To know the difference between Maildir and Mbox formats, read about them from below:
Maildir format was specifically made to remove the inadequacies of MBOX files. As messages in the Maildir directory are; saved in a new subdirectory in a tree form. Maildir can be accessed by multiple users at a time. There is a specific naming convention while storing messages in Maildir. In Maildir, any locking system is not required.
New: All the new incoming emails are stored in this subdirectory. To indicate a new mail to the user the date and time are written on it. For storing messages, a Maildir uses RFC 822 format to display Return-path and Delivered-to line.
Cur: This directory is the same as the New directory, but it stores only the mails that a user has read.
Tmp: Tmp stands for Temporary in a Maildir file extension. It ensures proper delivery of emails and stores all temporary emails.
MBOX is the traditional method to store emails on cPanel servers. Each message is saved in a single file and stored in the form of a series. To separate each message a marker is applied where the one message ends and the other begins. A single MBOX file can be accessed in the read/write mode. While multiple working, a locking mechanism is required to maintain data consistency.
Let’s clear out differences by knowing the advantages of using each file storage format:
Advantages of Maildir:
Advantages of MBOX:
These were the differences between Maildir and MBOX.
Here, I have mentioned the differences between Maildir and MBOX. I hope that you got an accurate knowledge of using a specific general format. Both formats have their concrete existence, and transferring a file is efficient with the MBOX format. But, viewing emails is much facilitated with the Maildir structured format.
