Question: Do you have to have a radically greater setting for maildir than for mbox? I would think... What sort of values are people using with both formats? Sounds like a nasty thing that could bite one in the $%# come migration from mbox to 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.
