Here's the setup I've inherited: All of the user home directories live on a NetApp filer. Okay, no big deal. The mboxes (inboxes, anyway) live on their own NetApp volume, and the user subdirectories live in their home directories. Our friends at NetApp informed me last week that the NetApp Filer has "problems" with MailDirs, particularly when the size of each directory exceeded 1% of the total system memory (six gig for this filer). So if I want to use MailDir format, I have to apparently restrict each user's quota to 60 megs. Somehow, in 2007, I think my users could still turn up an awful lot of torches and pitchforks were I to attempt such a thing. We have several webmail servers running now, but all told we have anywhere from between 20,000 and 60,000 accounts, though how many are active is a matter of some debate. If anyone has encountered this or similar issues I'd dearly love to hear about it, or failing that, a pointer to where I can air this particular Hobson's Choice in the hopes of gaining decent resolution.
