Having > 10 TByte mailstore filesystem-checks takes too much time.
At the moment we have four different partitions, but I don't like to set symlinks or LDAP-flags to sort customers and their domains to there individual mount-point. I'd like to work with mdbox:/mail/%d/%n to calculate the path automatically.
Why not symlinks? You could use e.g. /mail/%16Hu/%d/%n as part of the path which would give you one hex letter when hashing the username (0..9, a..f). So then you could create symlinks like:
/mail/0 -> /storage1 /mail/1 -> /storage2 ..etc..
I'm very interested in the feature "alternative mailstore" with mdbox, because that makes it very easy to use at least TWO filesystems without any tricky configuration.
I think I'd love to have <n> alternative mailstores. Why does dbox doesn't look for its m.*-files in more then two directorys? Sure, looking in 4 directorys would lead to four disc operations, but maybe it could be very helpful.
The current implementation uses a simple message flag to tell when/where to move the mail, so the code would have to get much more complicated with more alt paths.
