Converting Email from Eudora OS X to a modern format - the TidBITS review

My Eudora archive is in PC format. So converting to OS X is even more of a pain.

A pain I'll have to face sometime. As Eudora fades away conversion options narrow. So sometime soon ...

Today Adam Engst published the comprehensive conversion guide based on his experience with a million message archive. It's not pretty (emphases mine) ...

TidBITS Networking: Converting Email from Eudora: Why I No Longer Live at the P.O.

... Before you get started converting your Eudora mail, there are two cleanup tasks I recommend taking first (and another that I discuss in the Eudora Mailbox Cleaner section below). ... Before you convert your mail, you should compress your mailboxes, to make sure that any deleted messages that haven’t yet been removed from the actual mailbox file are not exported with the rest...

Second, if your Eudora Folder is anywhere near as old as mine, it dates to the classic Mac OS, where the / character was perfectly legitimate in filenames. If, like me, you used / in some mailbox names, you’re going to want to rename those mailboxes before converting them, since some utilities will see the / and create a new mail folder, thinking it’s a Unix directory...

... Apple Mail features a built-in Eudora importer that provides the most obvious approach for importing your Eudora archive. If it were the only option, it might be acceptable, but in my testing, it missed converting at least some very old mailboxes. In those it did import, it failed to bring in attachments, messages status, and labels. Worse, in many mailboxes, it appeared to duplicate messages...

... Apple Mail can also import Unix mailbox files, so the question becomes, how do you convert Eudora mailbox files into Unix mailbox files (the two formats are similar, but not identical)? There are a number of options here, including the standalone program Emailchemy and a utility called EudoraExport that’s embedded in Eudora OSE. I had good luck with Unix mailbox files created by EudoraExport...

... now that I have my entire Eudora archive in Apple Mail, I think I’m going to leave it there as well, in case I ever want to move it somewhere else. I’ll stick with either the version of my Eudora archive created by Eudora Mailbox Cleaner (which maintained some message status, along with attachments) or Eudora OSE’s EudoraExport (which didn’t maintain message status, but did bring in attachments and which seemingly found about 120,000 more messages). I’m not a fan of Apple Mail, but its future is guaranteed and I don’t need to use it for anything but access to this email archive...

I'm surprised Apple Mail can handle an archive this large, though Adam tells us search is very slow.
