Parse of pseudo-duplicate From line in mbox files

Hi,

I'm currently writing a tool to merge two mbox files and use Mail::Box modules for this purpose.

Unfortunately some of the mbox files contain a duplicate header like this

  From [email protected]  Sat Oct 23 13:40:27 2004
  >From tjahns  Sat Oct 23 13:40:27 2004

because the message was delivered with "procmail -f [email protected]" via fetchmail's mda mechanism.

Since the consume method of Mail::Message::Field::Fast tries to interpret the second >From as an ordinary header line, I get the following two results:

1) an error message stating a header line contains an illegal character.
2) (and this is the serious problem) when I write such a message to another file
    (with $message->copyTo()), it is mangled like this:

  >From tjahns  Sat Oct 23 13: 40:27 2004

  (notice the added space after 13:), because it's treated like a header.

Since mutt,balsa or gnumail and probably other email-programs I haven't tried have no problem parsing such mailboxes, I wanted to place a featurewish for Mail::Box to do the same.

I'm using libmail-box-perl (2.068-1) from debian etch.

If I can provide any further useful information (like snippets from my perl code), I'll happily do so.

Ciao, Thomas Jahns
