a hang when trying to COPY to a non existent mailbox via IMAP.
|
|
|
|
* Linux: Fixed a high system CPU usage / high context switch count
performance problem
* Maildir: Avoid unnecessarily reading dovecot-uidlist while opening
mailbox.
* Maildir: Fixed renaming child mailboxes when namespace had a prefix.
* mdbox: Don't leave partially written messages to mdbox files when
aborting saving.
* Fixed master user logins when using userdb prefetch
* lda: Fixed a crash when trying to send "out of quota" reply
* lmtp: If delivering duplicate messages to same user's INBOX,
create different GUIDs for them. This helps to avoid duplicate
POP3 UIDLs when pop3_uidl_format=%g.
* virtual storage: Fixed saving multiple mails in a transaction
(e.g. copy multiple messages).
* dsync: Saved messages' save-date was set to 1970-01-01.

* Services' default vsz_limits weren't being enforced correctly in
earlier v2.0 releases. Now that they are enforced, you might notice
that the default limits are too low and you need to increase them.
This problem will show up in logs as "out of memory" errors.
See default_vsz_limit and service { vsz_limit } settings.
* LMTP: In earlier versions if mail was delivered to user+detail@domain
address, LMTP server always attempted to deliver the mail to mailbox
named "detail". This was rather unintentional and shouldn't have been
the default. lmtp_save_to_detail_mailbox=yes setting now preserves
this behavior (default is no).
+ Added systemd support (configure --with-systemdsystemunitdir).
Based on patch by Christophe Fergeau.
+ Replaced broken mbox-snarf plugin with a new more generic snarf
plugin.
- dbox: Fixes to handling external mail attachments
- verbose_proctitle=yes didn't work for all processes in v2.0.7
- imap, pop3: When service { client_count } was larger than 1, the
log messages didn't use the correct prefix. Last logged in user's
prefix was always used, regardless of what user's session actually
logged it. Now the proper log prefix is always used.
- MySQL: Only the first specified host was ever used

dovecot2-pigonhole package. Back out the changes related to this.

* master: default_process_limit wasn't actually used anywhere,
rather the default was unlimited. Now that it is enforced, you might
notice that the default limit is too low and you need to increase it.
Dovecot logs a warning when this happens.
* mail-log plugin: Log mailbox name as virtual name rather than
physical name (e.g. namespace prefix is included in the name)
+ doveadm dump: Added imapzlib type to uncompress IMAP's
COMPRESS DEFLATE I/O traffic (e.g. from rawlog).
- IMAP: Fixed LIST-STATUS when listing subscriptions with
subscriptions=no namespaces.
- IMAP: Fixed SELECT QRESYNC not to crash on mailbox close if a lot of
changes were being sent.
- quota: Don't count virtual mailboxes in quota
- doveadm expunge didn't always actually do the physical expunging
- Fixed some index reading optimizations introduced by v2.0.5.
- LMTP proxying fixes

dovecot-sieve option (managesieve support is now included with sieve).
Create additional "dovenull" user for login processes. Add MESSAGE
with upgrade notes. Grab maintainership.
Major changes since 1.2:
* Dovecot uses two system users for internal purposes now by default:
dovenull and dovecot. You need to create the dovenull user or change
default_login_user setting.
* Global ACLs are now looked up using namespace prefixes. For example
if you previously had INBOX. namespace prefix and a global ACL for
"INBOX.Sent", it's now looked up from "INBOX.Sent" file instead of
"Sent" as before.
* Maildir: File permissions are no longer based on dovecot-shared file,
but the mailbox directory.
+ Redesigned master process. It's now more modular and there is less
code running as root.
+ Configuration supports now per-local/remote ip/network settings.
+ dsync utility does a two-way mailbox synchronization.
+ LMTP server and proxying.
+ Added mdbox (multi-dbox) mail storage backend.
+ doveadm utility can be used to do all kinds of administration
functions. Old dovecotpw and *view utilities now exist in its
subcommands.
+ imap and pop3 processes can now handle multiple connections.
+ IMAP: COMPRESS=DEFLATE is supported by imap_zlib plugin
+ director service helps NFS installations to redirect users always
to same server to avoid corruption

written with security primarily in mind. Dovecot is an excellent choice for both
small and large installations. It's fast, simple to set up, requires no special
administration and it uses very little memory.
