Maildir to Unix style mbox

Some tools, like SpamProbe, require your mailbox to be in mbox format.

A while ago I converted my mailboxes to maildir. But especially SpamProbe can only handle unix style mboxes.

Here is a little Python script reading a maildir and putting out mbox format on stdout:

import sys
import email
from email.Errors import BoundaryError, HeaderParseError
from mailbox import Maildir

maildir = sys.argv[1]

md = Maildir(maildir, email.message_from_file)

while True:
    try:
        mail = md.next()
    except (BoundaryError, HeaderParseError):
        continue
    if mail is None:
        break
    print mail.as_string(True)
