Upgrading Dovecot v2.0 to v2.1
==============================
v2.1 is mostly compatible with v2.0 configuration, except:
* 15-mailboxes.conf included in the default configuration now specifies a few
default SPECIAL-USE [http://tools.ietf.org/html/rfc6154] mailboxes. This
file assumes that you already have 'namespace inbox { .. } ' specified (in
10-mail.conf). If you don't, you'll get errors about namespaces. Note that
the namespace's name must be "inbox" (as well as usually include inbox=yes
setting). The solution is to either make sure that you have such a namespace
defined, or you can simply delete the 15-mailboxes.conf if you don't care
about SPECIAL-USE.
* <Plugins.txt> now use UTF-8 mailbox names rather than mUTF-7: acl,
autocreate, expire, trash, virtual
* Usernames in authentication are now lowercased by default.
* Non-lowercase usernames in password/user database result in "unknown
user" errors
* To allow mixed case usernames again, set 'auth_username_format=' (i.e. to
empty)
* <Solr> [Plugins.FTS.Solr.txt] full text search backend changed to use
mailbox GUIDs instead of mailbox names, requiring reindexing everything.
solr_old backend can be used with old indexes to avoid reindexing, but it
doesn't support some newer features.
* <Expire plugin> [Plugins.Expire.txt]: Only go through users listed by userdb
iteration. Delete dict rows for nonexistent users, unless
expire_keep_nonexistent_users=yes.
* <dsync> [Tools.Dsync.txt] was merged into doveadm. There is still "dsync"
symlink pointing to "doveadm", which you can use the old way for now. The
preferred ways to run dsync are "doveadm sync" (for old "dsync mirror") and
"doveadm backup".
* dsync protocol isn't compatible with v2.0's dsync, so you can't dsync
between v2.0 and v2.1 servers.
