Hi, Nick.

I dealt with Eudora's mailbox format some time around 1998.  Eudora
didn't store messages in the conventional text-only mailbox format
using "From " as the delimiter at the start of the file.  Your example
suggests this as you only have the "From:" header field not the "From
" message delimeter.

As Eudora mailboxes contain no inline message delimeters, Eudora also
stored message offsets in a binary file which you could poke at with
pack() to pull out the messages in the mailbox.  Various people had
documented the format of the binary files on the Web, even back then.

This is all off the top of my head.  My memories may have become
confused over time.

Wikipedia has a good explanation of the mailbox format I describe

Also you might like to look at Tie::Eudora on CPAN, although I don't
know how well it might work.

Finally, congratulations on keeping better backups than I do. :)
