Since it's void of any locks, what would be wrong with maildir in AFS?

There's a bunch of things wrong with stock maildir; I've done a lot of work with it. Our site uses a "modified" version of the maildir filestructure for mail storage, and it performs quite well over AFS -- we've got multiple distributed delivery systems, as well as multiple loadbalanced imap/pop readers.

Here's a link to our c-client & procmail patches that we've been using:

and

It's not completely void of locks, though, but since AFS does implement file-level locks, it works fine. (the lock has to do with being able to guarantee uniqness of UIDs for messages -- but it's used very sparingly ;) )
