Close to 20 years ago I moved from mbox to cyrus and have never looked back. I did learn that the Ext file systems had some issues bit big directories and for a lot of years I used reiserfs. It seems that recent Ext filesystems have the big directory problem fixed. In those early years I had Ext give me more than a few bad days. On 12/14/2015 01:36 PM, Lennart Sorensen wrote:

I found it interesting that ReiserFS was pointed at as having amongst the best handling of errors, passing them back sensibly to applications. It better have good error handling given how many insane errors it often generates (in my experience). It is not a place I want to store my data anymore.
Also interesting was that they pointed at using SQLite as a way of mostly hiding applications from worrying about such troubles.
Also entertaining was the notion of "MBox considered harmful"; makes me like MH and Maildir all the better, as they have the merit of storing a message per file, so that there's fewer concurrency issues surrounding re-opening files and rewriting them. (Possibly I'm wrong, and the problem just shifts to directory metadata access...) Well deleting a message requires deleting a file, not rewriting the entire mbox after that message, so Maildir is a good idea.
