https://dovecot.org/releases/2.2/dovecot-2.2.27.tar.gz https://dovecot.org/releases/2.2/dovecot-2.2.27.tar.gz.sig Note that the download URLs are now https with a certificate from Let's Encrypt. * dovecot.list.index.log rotation sizes/times were changed so that the .log file stays smaller and .log.2 is deleted sooner. + Added mail_crypt plugin that allows encryption of stored emails. See http://wiki2.dovecot.org/Plugins/MailCrypt + stats: Global stats can be sent to Carbon server by setting stats_carbon_server=ip:port + imap/pop3 proxy: If passdb returns proxy_not_trusted, don't send ID/XCLIENT + Added generic hash modifier for %variables: %{<hash algorithm>;rounds=<n>,truncate=<bits>,salt=s>:field} Hash algorithm is any of the supported ones, e.g. md5, sha1, sha256. Also "pkcs5" is supported using SHA256. For example: %{sha256:user} or %{md5;truncate=32:user}. + Added support for SHA3-256 and SHA3-512 hashes. + config: Support DNS wildcards in local_name, e.g. local_name *.example.com { .. } matches anything.example.com, but not multiple.anything.example.com. + config: Support multiple names in local_name, e.g. local_name "1.example.com 2.example.com" { .. } - Fixed crash in auth process when auth-policy was configured and authentication was aborted/failed without a username set. - director: If two users had different tags but the same hash, the users may have been redirected to the wrong tag's hosts. - Index files may have been thought incorrectly lost, causing "Missing middle file seq=.." to be logged and index rebuild. This happened more easily with IMAP hibernation enabled. - Various fixes to restoring state correctly in un-hibernation. - dovecot.index files were commonly 4 bytes per email too large. This is because 3 bytes per email were being wasted that could have been used for IMAP keywords. - Various fixes to handle dovecot.list.index corruption better. - lib-fts: Fixed assert-crash in address tokenizer with specific input. - Fixed assert-crash in HTML to text parsing with specific input (e.g. for FTS indexing or snippet generation) - doveadm sync -1: Fixed handling mailbox GUID conflicts. - sdbox, mdbox: Perform full index rebuild if corruption is detected inside lib-index, which runs index fsck. - quota: Don't skip quota checks when moving mails between different quota roots. - search: Multiple sequence sets or UID sets in search parameters weren't handled correctly. They were incorrectly merged together.
