It's a binary format used by pine and IMAP. It essentially contains the
straight text mail messages, with a CRLF convention, but surrounded by
header information containing message length etc. information, to allow
quick searches and lookups.

It's undocumented as a format. The author informs me that he likes to keep
it that way so that people access it through the IMAP API.

One exists as part of the imap-utils. It's called mbxcvt and can convert
from any recognised mailbox format to any other
