forward port SVN commit 578481 by dkukawka:

* fixed import of mboxes from maillinglist archives which contain a 
  line in the mailheader starting with "From " (instead of "From: ").
  This should allow to move imported mails to IMAP servers (Cyrus 
  e.g. don't accept mail with such a header line)
