Mathematica Import/Export Format

MBOX (.mbox, .mbx)

Unix mailbox format.
Holds a collection of electronic mail messages.
Native archive format of email clients such as Unix mail, Eudora, Mozilla, Netscape, and Thunderbird.
ASCII format.
Stores mailbox messages in their original format, with individual messages concatenated and separated by an empty line.
May contain binary attachment files using an ASCII representation.
Email applications normally use improved versions of the original Unix mbox format.

Import supports all common variants of the mbox file format.

IMPORT

Import["file.mbox"] imports an mbox file, returning the entire contents as rules.

Import["file.mbox"] returns an expression of the form {msg₁, msg₂, ...}, giving the individual mail messages msg_i in the form {"From" -> str₁, "To" -> str₂, ...}.

Import["file.mbox", elem] imports the specified element from an mbox file.

Import["file.mbox", {elem, sub_a, sub_b, ...}] imports a subelement.

Import["file.mbox", {{elem₁, elem₂, ...}}] imports multiple elements.

The import format can be specified with Import["file", "MBOX"] or Import["file", {"MBOX", elem, ...}].

See Import for full general information.

ImportString supports the mbox format.
