- In general, we should be NFS-safe. - NFS server must support fcntl() locking currently. It's possible to add file-based locking code, but I haven't bothered. - Modifylog uses fcntl() for figuring out when to delete the log file, and assumes that changing file locking between F_RDLCK / F_WRLCK is atomic (not sure if this is the case with all operating systems, I hope so). This anyway could be more difficult to change not to use fcntl(). - gethostname() must return different name for each IMAP server accessing a user's mailboxes - Clocks should be somewhat synchronized: - maildir: One minute difference is enough to have a small chance of new mail to get temporarily lost until more mail arrives. - One hour is enough to create a problem when two imap servers try to open the same mailbox at the same time.
