We are now more forgiving of MIME boundry headers generated by earlier
versions of eudora. However, if you have messages already in the mailstore
that you want to fix you will need to reconstruct the affected mailboxes
to regenerate the cached bodystructure data to take this into account.
Nothing needs to be done for new messages to be treated in this way.
Upgrading from 2.1.12 or earlier
timsieved was corrected to behave properly in the altnamespace configuration.
However, this means that it was previously looking for sieve scripts in
"user.name" format instead of the (correct) "user^name"
format. A sample script to do this (which should be run in the top level of
the sieve directory) is in tools/convert-sieve.pl. Note that this
is only needed if you are running with altnamespace turned on.
Upgrading from 2.1.3 or earlier
If you use notifications (previously notify_zephyr or
notify_unix) this functionality has been seperated out to
notifyd. See the notifyd manpage and example
entries in master/conf.
Upgrading from 2.1.2 or earlier
Sieve has been updated to be compliant with RFC 3028 and
draft-martin-sieve-notify-01. All notify actions and any
fileinto and/or redirect actions using stringlists
will have to be updated/changed.
If you use timsieved to manage Sieve scripts, and have
enabled the alternate namespace and/or the Unix hierarchy separator,
run the script "tools/translatesieve". This script will
translate the folder names in fileinto actions.
Cyrus now uses the service name "sieve" instead of "imap" for the
SASL profile of timsieved. If you use timsieved to
manage Sieve scripts, be sure to update your password checking
mechanism appropriately,
If you have enabled the improved directory hashing scheme, run
the script "tools/rehash full". This script will rehash your
existing directories.
The hashed deliver databases (used for duplicate delivery suppression
and Sieve) have been merged into a single deliver.db database.
You can safely remove the entire /var/imap/deliverdb
directory structure after shutting down the server.
All of the Cyrus databases have been unified under a single DB3
environment. A new ctl_cyrusdb tool is now used for database
recovery and checkpointing instead of ctl_mboxlist and
ctl_deliver. You should replace the appropriate START and
EVENTS entries in cyrus.conf with those in the
sample configurations in the master/conf directory.
Cyrus now caches SSL/TLS sessions in an external database. If you
have support for SSL/TLS, and haven't disabled session caching (see
imapd.conf(5)), you should add a line like the following to
the EVENTS section of cyrus.conf to prune expired
sessions from the database:
# this is only necessary if caching TLS sessions
tlsprune cmd="tls_prune" period=1440
Upgrading from 2.0.6, 2.0.7, 2.0.8, or 2.0.9 or earlier
If you use timsieved to manage Sieve scripts, run the
script "tools/upgradesieve". timsieved now uses
symlinks instead of hard links.
Upgrading from a previous 2.0 version to 2.0.6
Warning: You do not need to follow these instructions if you're
upgrading from version 1.6.
You can now pick whether to use Berkeley db to store seen state,
the subscription files, and the mailboxes file or a flat text file, at
compile time only. (Look in imap/seen_db.c and
imap/mboxlist.h.)
The format of the mailboxes file and seen state has changed. It is
not possible to preserve seen state, but upgrade the mailboxes file as
follows:
Run ctl_mboxlist -d > mboxlist.temp to dump existing
mailboxes.
Remove old database files: rm mailboxes.db db/*
user/*/*.seen
With the new version of ctl_mboxlist, run ctl_mboxlist -u <
mboxlist.temp.
Upgrading from 1.6.22 or 1.6.24
Warning: Cyrus imapd 2.0 will automatically convert on-disk
file formats as the server is used. It is not possible to run 1.6
after 2.0 has been used on a mail spool without reconstructing every
mailbox.
Create some extra directories and remove the duplicate delivery
database:
su cyrus
cd /var/imap
ctl_mboxlist -u < mailboxes
ctl_cyrusdb -c
Please keep a backup of your mailboxes file. You can dump an
old-style mailboxes file by using ctl_mboxlist -d.
remove "/etc/inetd.conf" entries. The imap and
popd3d lines need to be removed from /etc/inetd.conf
and inetd needs to be restarted.
master process configuration: You'll need to configure the master
process Cyrus process and ensure that it starts on boot. see this section of the
configuration instructions.
MTA configuration. You will have to reconfigure your MTA to speak
to lmtpd. See this section of
the configuration document.
cyrus.seen conversion. The cyrus.seen file will be automatically
upgraded as users read mail. After some time, you might want to
delete the cyrus.seen file in each mailbox; it is superceded by the
user/joe.seen file.
cyrus.index conversion. The cyrus.index file will be
automatically upgraded the first time each mailbox is SELECTed.
Netnews conversion. The netnews programs are no longer built. If
you are using netnews, you will need to apply the diff in the
netnews/ directory to INN or see if INN is now distributing
those changes. You will also want to run remotepurge on a
regular basis to purge old netnews posts.
Upgrading from 1.6.13
Upgrading from the Cyrus IMAP server version 1.6.13 or earlier:
if you use Sieve, you should run the "tools/upgradesieve"
script, as the format of the "/usr/sieve" directory has
changed slightly.
timsieved, included in this release, will handle maintenance of Sieve
scripts.
Upgrading from the Cyrus IMAP server version 1.6.10 or earlier:
if you export news via the IMAP server, you'll have to change your
"newsfeeds" file to contain
collectnews!:*:Tf,WR:collectnews
The format of the
input to collectnews has changed.
Duplicate delivery suppression is now required for Sieve.
Upgrading from the Cyrus IMAP server version 1.6.1 or earlier
(including 1.5.x!): the quota and user directories are now hashed by
the first character of the username. This is to reduce the number of
entries in any given directory. It doesn't do a great job (and in some
cases it will do a really poor job) but as a quick hack it shouldn't
make things worse. Optionally, the data partitions can also be hashed
by enabling the "hashimapspool" option.
You must hash your directories using the "dohash" script
in the tools subdirectory. (If you want to hash your mail spool, be
sure to set "hashimapspool" before running "dohash".) This
must be run as the Cyrus user. Be sure to stop mail service while
converting. Doing this in single user mode is probably the safest.
Upgrading from 1.5
Upgrading from the Cyrus IMAP server version 1.5 or earlier:
libsasl is now required. Configuring SASL to work may be a chore,
especially if you use shadow passwords.
Make sure to read the upgrading instructions under 1.6 above.
Upgrading from 1.5.14 or earlier requires deleting the delivered
database. Remove the file delivered.db in the configdirectory and make a
directory called "deliverdb" in the configdirectory. This may cause some
duplicates to get through.
Upgrading from 1.5.14 or earlier requires removing the PTS cache
database (if the AFS PTS group support is used, which is not the
default). The PTS cache is in /var/ptclient/ptscache.db, and you
should remove it. This is because the format for the PTS cache for
IMSP has changed. If you use AFS ACLs, IMSPd, and IMAPd on the same
machine, make sure you have version 1.5a5 of the IMSP server for this
version of the IMAP server. (If you don't have IMSP, or AFS, don't
worry about it.)
