This is a very small scale server, especially compared to yours!
It originally ran on a PII-266 with 512M Ram. It's a VM now. :) It does
handle 10's of Gs of email quite nicely though.
The tune2fs command can be used to change settings. See the man page.
You can change settings on the fly. I think the dir_index gets built on
the fly, but I'm not positive about this. You might want to check up on
that. It's a highly recommended option for ext3 Maildirs though.
