mbox is a Go library to parse mbox files. It currently supports the mboxrd format used for example for Google Mail exports.

The basic use case is to open a mailbox file and read its messages. The following code does not include error handling.

mbox, _ := mbox.Open(path, mbox.Mboxrd)

for {
    msg, _ := mbox.Read()
    if msg == nil {
        break
    }

    fmt.Printf("%s\n", msg.Id)
}

mbox.Close()

The mbox directory contains a tool to work with mbox files. Commands and options can be displayed with mbox -h.
