Whew!!! Thank goodness that works! Although I'm a little surprised that it does. By my reading of the documentation, the INBOX: part of mail_location (default_mail_env) is used specifically for mbox mail stores because mbox files cannot have both messages and directories, making it necessary to somehow distinguish the INBOX mbox containing the messages from the mbox listing the folders on the server.

I was actually expecting the answer to be something like, "can't be done using mail_location for maildir. The only way to store mail seperately is to create a second private namespace something like:"

mail_location = maildir:/data/fast/%Ld/mail/%Ln:INDEX=/data/fast/%Ld/indices/%Ln

namespace private { separator = / prefix = inbox = yes hidden = yes }

namespace private { separator = / prefix = "archives/" location = maildir:/data/deep/%Ld/mail/%Ln }

"and train your users how to use it." Incidentally, this answer would work as well wouldn't it? Would this provide "archives" at the same level as Inbox in a namespaces aware email client with the ability to create folders under "archives" that would be stored seperately from folders created outside of "archives"?

Just for completeness, is there an officially sanctioned way of configuring dovecot to store certain arbitrary maildir folders in specific separate locations?

Thanks very much for your help.

I'd like to store all of my mail in maildir, but I want to store the inbox and indices on fast storage and everything else on deep storage. Does the following configuration value for mail_location accomplish this?

mail_location = maildir:/data/deep/%Ld/mail/%Ln:INBOX=/data/fast/%Ld/mail/%Ln:INDEX=/data/fast/%Ld/indices/%Ln

I have the following setup:

default_mail_env = maildir:/var/maildir/%u/:INBOX=/var/mail/inboxes/%u/:INDEX=/var/mail/indexes/%u/index

/var/maildir is a nfs mounted directory on a filer /var/mail is local

I'm running rc2, so maybe default_mail_env is now named mail_location

in this case, you don't need a specific namespace setup.

for compatibility reasons for clients which have a 'Imap Directory' setting my namespaces ook like this:

namespace private { separator = / prefix = inbox = yes }

namespace private { separator = / prefix = ~/MailImap/ hidden = yes }

namespace private { separator = / prefix = /home/%u/MailImap/ hidden = yes }

namespace private { separator = / prefix = ~/mailIMAP/ hidden = yes }

...

If not, does the following configuration accomplish this with namespaces?

mail_location = maildir:/data/fast/%Ld/mail/%Ln:INDEX=/data/fast/%Ld/indices/%Ln

namespace private { separator = / inbox = yes hidden = yes prefix = location = }

namespace private { separator = / hidden = yes prefix = ??? location = maildir:/data/deep/%Ld/mail/%Ln/??? }

---

Actually, I can't quite finish the namespace configuration. I'd like to set something like:

prefix = * location = maildir:/data/deep/%Ld/mail/%Ln

But I suspect the '*' won't actually match everything, and even if it did, I suppose it would also match the inbox. I began with listing any and every typical folder in its own namespace like:

namespace private { separator = / hidden = yes prefix = drafts location = maildir:/data/deep/%Ld/mail/%Ln/drafts }

namespace private { separator = / hidden = yes prefix = templates location = maildir:/data/deep/%Ld/mail/%Ln/templates }

namespace private { separator = / hidden = yes prefix = sent location = maildir:/data/deep/%Ld/mail/%Ln/sent }

and so on, but that doesn't seem very elegant. Also, namespaces scare me for client compatibility. Am I missing something obvious?

the prefix setting is not for defining which folder is where, prefix defines where dovecot will look for mail, if a client has the 'Imap Server Directory' set to this value.
