What sort of values are people using with both formats? Sounds like a

maildir
No, there's pretty much no difference in fd usage between mbox and
maildir. The main problem is the Dovecot master process, since it uses
1-2 fds per child process.
It's more of a client/server activity and usage issue than anything
else. Based on lsof on individual processes, there doesn't seem to be
anything unique to maildir but I don't have any mbox or dbox experience.
O/S tweaks are no limited to dovecot, you get into these issues with
databases and webservers. To be honest, I only knew to look into these
issues because of settings needed to Oracle/MySQL/Apache/etc servers.
Tuning isn't limited to just ulimit. I know of some useful RHE settings,
but not all.
