MBOX stands for Mailbox. MBox file format represents a container for a collection of electronic mail messages. MBOX is a file extension for a text file that is used for storing and organizing a collection of email messages. The MBOX file is supported or created by several email applications like SeaMonkey, Thunderbird, Apple Mail, etc. The most used format for storing e-mail messages on a hard drive is the mbox format, in which all the messages are stored as a single, long, text file. The messages are stored inside the container with their attachments.
A message in the MBOX file format is specified by "From" with a white space character and at the end of every message, it is specified with a blank line. "From" means the line in the messages and the header starts with F,r,o,m, and space.
It is a type of email file, which stores messages in plain text format. The MBox file format remained non-standardized for a quite long time until 2005. Each message in Mbox begins with a separate line that identifies the message sender, and also the date and time at which the message was received. Well, there are some variants of MBOX file formats: mboxo, mboxrd, mboxcl, and mboxcl2. These will be clear to understand as mentioned:
Mboxo: It is different from the original Mailbox file because it uses constant strings like "???@???". Original MailBox uses the email address of the sender.
Mboxrd: It is basically the variation of mboxo mailbox, where the initial point of a message is described either in form of header or body.
Mboxcl: This format of the MBOX file is operated in 'Unix System v'. When new mail is appended to the mboxcl mailbox, it is transformed into the file before appending.
Mboxcl2: It is similar to mboxcl. It does not scan for 'From' lines. Each mboxcl2 comprises the content-length attribute in its header part.
MBOX stores all its data at a default location. There is no native location where one can find the MBOX file. Well, depending upon the email application and platform.
