Posted to the list there, but if anyone's done this before, I'd appreciate a bit of guidance. Begin Crosspost: I've got a poorly conceived and implemented system I'm trying to migrate off of. Right now we've got 20K accounts or so, in mbox form, under UW-IMAP. Eventually we're going to move to Maildir format, but the first step is to move to Dovecot on one of our imap servers as a proof of concept. In other words, all config changes have to take place on the dovecot side, until I get PHB approval to proceed further. Right now, the inboxes are the user's username, located in /var/mail (an NFS mounted volume). So my inbox would be at /var/mail/chandler. The sub-mailboxes are in the user home directories, just scattered around-- no /mail subdirectory or anything close. So there's a folder called ~chandler/INBOX.Sent, ~chandler/INBOX.Trash, and a ~chandler/Dovecot (for this list). The list of these files is kept in ~chandler/.mailboxlist. I attempted to follow the instructions at http://wiki.dovecot.org/Migration about: You can either rename your .mailboxlist file to .subscriptions for all your users using uw2dovecot.sh <http://wiki.dovecot.org/uw2dovecot.sh>, or change the definition of SUBSCRIPTION_FILE_NAME in /src/lib-storage/subscription-file/subscription-file.c/. In 1.0-test, this value is defined in /src/lib-storage/subscription-fileindex/maildir/maildir-storage.h/ and /src/lib-storage/subscription-fileindex/mbox/maildir-storage.h/. .subscriptions is located inside of the mail directory, whereas it is possible .mailboxlist was outside of it (in user's home directory). However, I built dovecot from ports on FreeBSD 6.2, and the only files that approach this are: wurfel# ls -al total 58 drwxr-xr-x 3 root wheel 512 Jan 16 20:48 . drwxr-xr-x 6 root wheel 1024 Jan 16 20:48 .. drwxr-xr-x 2 root wheel 512 Jan 16 20:48 .deps -rw-r--r-- 1 root wheel 14662 Jan 16 20:48 Makefile -rw-r--r-- 1 root wheel 266 Oct 20 2004 Makefile.am -rw-r--r-- 1 root wheel 14009 Jan 6 23:26 Makefile.in -rw-r--r-- 1 root wheel 4374 Jan 16 20:48 libstorage_subscription_file.a -rw-r--r-- 1 root wheel 6935 Jan 3 15:19 subscription-file.c -rw-r--r-- 1 root wheel 703 Jan 13 2006 subscription-file.h -rw-r--r-- 1 root wheel 4060 Jan 16 20:48 subscription-file.o wurfel# pwd /usr/ports/mail/dovecot/work/dovecot-1.0.rc17/src/lib-storage/subscription-file I took a look at subscription-file.c, but didn't notice where I should change the definition of the file itself-- my code-fu is weak.
