[Dovecot-news] v2.2.8 released



+ Mail cache lookups work for the mail being saved. This improves performance by avoiding the need to parse the mail multiple times when using some plugins (e.g. mail_log).
+ Mail cache works for recently cached data also with in-memory indexes.
+ imapc: Many performance improvements, especially when working with dsync. Also added imapc_feature=fetch-headers which allows using FETCH BODY.PEEK[HEADER.FIELDS (..)] to avoid reading the entire header.
+ mail_location = ..:FULLDIRNAME=dbox-Mails is the same as :DIRNAME=dbox-Mails, but it will also be used for :INDEX and :CONTROL directories. (It should have worked this way from the beginning, but can't be changed anymore without breaking existing installations).
- Fixed infinite loop in message parsing if message ends with "--boundary" and CR (without LF). Messages saved via SMTP/LMTP can't trigger this, because messages must end with an "LF.". A user could trigger this for him/herself though.
- lmtp: Client was sometimes disconnected before all the output was sent to it.
- imap_zlib plugin caused crashes during client disconnection in v2.2.7
- replicator: Database wasn't being exported to disk every 15 minutes as it should have. Instead it was being imported, causing "doveadm replicator remove" commands to not work very well.
