[Techtalk] df isn't accurate?

[jennyw]

Lovely! That's probably it ... I deleted 40,000 or more files when I had
the problem and it started working again. I'm now at 94% of inodes used
... I had no idea there was a limit here! Something to learn ... Maybe
I'll try Reiser or something for e-mail since it seems appropriate for
something like Maildirs ...

Thanks!
