[Dovecot-news] Dovecot v2.3.8 released
Binary packages in


+ Added mail_delivery_started and mail_delivery_finished events, see for details.
+ dsync-replication: Don't replicate users who have "noreplicate" extra field in userdb.
+ doveadm service status: Show total number of processes created.
+ When logging to syslog, use instance_name setting's value for the ident. This commonly is added as a log prefix.
+ Base64 encoding/decoding code was rewritten with additional features. It shouldn't cause any user visible changes.
- v2.3.7 regression: If a folder only receives new mails without any other mail access, dovecot.index.log keeps growing forever and dovecot.index keeps being rewritten for every mail delivery.
- dsync-replication may lose keywords after syncing mails restored from another replica. This only happened if the mail only had keywords and no system flags.
- event filters: Non-textual event fields could not be filtered using wildcards.
- auth: Scope parameter was missing from OAuth password grant request.
- doveadm client-server communication may hang in some situations. It is also using unnecessarily small TCP/IP packet sizes.
- doveadm who and kick did not flush protocol output correctly.
- imap: SETMETADATA with literal value would delete the metadata value instead of updating it.
- imap: When client issues FETCH PREVIEW (LAZY=FUZZY) command, the caching decisions should be updated so that newly saved mails will have the preview cached.
- With mail_nfs_index=yes and/or mail_nfs_storage=yes setuid/setgid permission bits in some files may have become dropped with some NFS servers. Changed NFS flushing to now use chmod() instead of chown().
- quota: warnings did not work if quota root was noenforcing
- acl: Global ACL file ignored the last line if it didn't end with LF.
- doveadm stats dump: With JSON formatter output numbers using the number type instead of as strings
- lmtp_proxy: Ensure that real_* variables are correctly set when using lmtp_proxy.
- event exporter: http-post driver had hardcoded timeout and did not support DNS lookups or TLS connections.
- auth: Fix user iteration to work with userdb passwd with glibc v2.28.
- auth: auth service can crash if auth-policy JSON response is invalid or returned too fast.
- In some rare situations "ps" output could have shown a lot of "?" characters after Dovecot process titles.
- When dovecot.index.pvt is empty, an unnecessary error is logged:  Error: .../dovecot.index.pvt reset, view is now inconsistent
- SMTP address encoder duplicated initial double quote character when the localpart of an address ended in '..'. For example "[[email protected]](mailto:user%[email protected])" became ""user+.."@[]( in a sieve redirect.
