Thunderbird only offers to create another account in the format "Unix Mailspool (Movemail)".
What is this format? It looks different from "Maildir".

MBOX File Format
Mailbox file (Berkeley Unix)
MBOX is a file extension for a text file used to organize and store e-mail messages. MBOX stands for MailBOX.
The MBOX file is the most common format for storing email messages on a hard drive. All the messages for each mailbox are stored as a single, long, text file in a string of concatenated e-mail messages, starting with the “From” header of the message. MBOX files were used predominantly on Unix. MBOX files are still used with several current e-mail clients, including Mozilla Thunderbird, Microsoft Entourage and Qualcomm Eudora.
