Not if the write fails in mid-stream.

Well I suppose that's one failure mode which could lose the entire mailbox.

The only failure I've experienced with mbox was one where either the first two or three, (or possibly the last, it's been a while and I forget) emails in the mailbox got corrupted. I could still see their content when I opened the file in a text editor, but in the mail clients they showed up with blank headers and no body.

Remember the recent kerfuffle regarding KDE assuming that the way ext3 works is hows every file
system works, and thus losing config files on ext4 partitions?

No. Got a link?

you could write a recovery utility, if one doesn't already exist.
But yes, I agree, maildir is better than mbox because you're likely
to lose no more than one message in the event of corruption. But
keep in mind that when Netscape 2 came out, mbox really was the
standard -- these days I'd say only old dinosaurs use mbox.
90+% of the people using Tbird still use mbox...

Like I said, old dinosaurs.

A few months back, I broke my Kmail config, and decided I'd check out Thunderbird (I haven't used it since it was part of Netscape 3). I gave it a good go, I really did, but it felt like I was being asked to do carpentry with my hands cuffed together and a small monkey riding on my back hitting me with over-ripe bananas.

How so? I've used Tbird for years, after having used Evolution, KMail (back in the KDE 2.x days) and Nutscrape 2.x-4.78.

(But then, I and my family use the IMAP interface. Years ago, I set up postfix/SA/malidrop and fetchmail in cron jobs running every 5-6 minutes for the 4 users of our LAN.)

I wouldn't say it is unusable, but I think it's aimed at users whose expectations are lower than mine.

That's not to say that Kmail doesn't have its problems too... all software sucks, it's just that some sucks less than others.

And at least mbox is a text format, and you have one file per mail
box, and not one giant undocumented binary file for all mail boxes
like Exchange uses.

It's the undocumented part that disturbs me.

If you're worried about mbox corruption losing an entire mail box, you should be worried about Exchange corruption losing every mail box for every user.

I'm also sure that "they" really screwed the pooch when designing
the PST file format.  The Outlook XP format, though, does seem to
perform better than the older version.

Yeah, but that's not saying much.
