variable forwarding buglet
by Jan-Pieter Cornet 22 Jun '18

22 Jun '18

I wanted to forward information from the director to the backend dovecot (original login name), so I had the userdb on the director return a forward_ologin variable. However, when I tried to use that variable in the "password_key" query on the backend dovecot, ${forward_ologin} was expanded to UNSUPPORTED_VARIABLE_forward_ologin. After testing a bit and looking around in the source a bit, and turning on debugging logging, it appeared that the forwarded variables actually appear as "passdb/userdb extra fields". So in my case, the forwarded information is available as %{passdb:forward_ologin}. So, problem solved, but this is either an implementation bug, or a documentation bug, or oversight. -- Jan-Pieter Cornet <johnpc(a)xs4all.net> Systeembeheer XS4ALL Internet bv www.xs4all.nl

v2.3.2 release candidate released
by Timo Sirainen 19 Jun '18

19 Jun '18

https://dovecot.org/releases/2.3/rc/dovecot-2.3.2.rc1.tar.gz https://dovecot.org/releases/2.3/rc/dovecot-2.3.2.rc1.tar.gz.sig v2.3.2 is mainly a bugfix release. It contains all the changes in v2.2.36, as well as a bunch of other fixes (mainly for v2.3-only bugs). * old-stats plugin: Don't temporarily enable PR_SET_DUMPABLE while opening /proc/self/io. This may still cause security problems if the process is ptrace()d at the same time. Instead, open it while still running as root. + doveadm: Added mailbox cache decision&remove commands. See doveadm-mailbox(1) man page for details. + doveadm: Added rebuild attachments command for rebuilding $HasAttachment or $HasNoAttachment flags for matching mails. See doveadm-rebuild(1) man page for details. + cassandra: Use fallback_consistency on more types of errors + lmtp proxy: Support outgoing SSL/TLS connections + lmtp: Add lmtp_rawlog_dir and lmtp_proxy_rawlog_dir settings. + submission: Add support for rawlog_dir + submission: Add submission_client_workarounds setting. + lua auth: Add password_verify() function and additional fields in auth request. - doveadm-server: TCP connections are hanging when there is a lot of network output. This especially caused hangs in dsync-replication. - Using multiple type=shared mdbox namespaces crashed - mail_fsync setting was ignored. It was always set to "optimized". - lua auth: Fix potential crash at deinit - SSL/TLS servers may have crashed if client disconnected during handshake. - SSL/TLS servers: Don't send extraneous certificates to client when alt certs are used. - lda, lmtp: Return-Path header without '<' may have assert-crashed. - lda, lmtp: Unencoded UTF-8 in email address headers may assert-crash - lda: -f parameter didn't allow empty/null/domainless address - lmtp, submission: Message size limit was hardcoded to 40 MB. Exceeding it caused the connection to get dropped during transfer. - lmtp: Fix potential crash when delivery fails at DATA stage - lmtp: login_greeting setting was ignored - Fix to work with OpenSSL v1.0.2f - systemd unit restrictions were too strict by default - Fix potential crashes when a lot of log output was produced - SMTP client may have assert-crashed when sending mail - IMAP COMPRESS: Send "end of compression" marker when disconnecting. - cassandra: Fix consistency=quorum to work - dsync: Lock file generation failed if home directory didn't exist - Snippet generation for HTML mails didn't ignore &entities inside blockquotes, producing strange looking snippets. - imapc: Fix assert-crash if getting disconnected and after reconnection all mails in the selected mailbox are gone. - pop3c: Handle unexpected server disconnections without assert-crash - fts: Fixes to indexing mails via virtual mailboxes. - fts: If mails contained NUL characters, the text around it wasn't indexed. - Obsolete dovecot.index.cache offsets were sometimes used. Trying to fetch a field that was just added to cache file may not have always found it.

TCP replication: high connection rate and looping in incomplete state
by tok 17 Jun '18

17 Jun '18

Hi, I am trying to establish TCP(s)-based replication between two FreeBSD 11.1 machines, both running Dovecot 2.2.35 (via pkg) with 10 virtual users and 1.2GB maildir. I followed the Wiki description (https://wiki2.dovecot.org/Replication) just skipped the SSH part. My resulting configurations are attached below. Problem: After reloading both Dovecot instances, a few seconds later they start to initiate connections in an absurdly high rate (30-50 new connections during 10 secs, closing old ones after 2-3 secs) and even after 1 hour they do not „calm down". E-mails are copied, but judging by size and file count, not completely (approx. 1GB and maybe 90% of files are getting synced). What is going on here? On the destination host (with empty storage before replication) I see "incremental - Waiting for dsync to finish“ in dsync-status, constantly flipping between handshake and waiting, for solely 4 out of 10 accounts. Replicator status says 0 requests and 10 total users. On the source host, replicator status says 4 queued full resyncs, 3 waiting failed and 10 total users. I already tried both tcps and tcp; activating debug log did not reveal any errors (e.g. SSL). Would be happy for any advice to track this down.

Hi Looks like I have got in a situation with missing or corrupted attachments. I am getting from time to time lmtp(17147, user1(a)example.com) Error: read(attachments-connector(zlib(/var/spool/mail/example.com/user2/mail/stor… failed: read(/srv/attachments/user2/4a/e0/4ae062027dd745f56c2cc1c43fa4f349f52986a0-2bcf4e063994235bfb4200006f28d014[base64:19 b/l]) failed: Stream is smaller than expected (0 < 5098) Replication works, but is there a way to recover the logic even with empty files or cleaning indices? Thanks Vladimir

After logrotation Dovecot still writes to old log file
by Michael Heuberger 15 Jun '18

15 Jun '18

Hi there This is weird. On my latest Ubuntu server Dovecot seems to write to /var/log/dovecot.log.1 instead of a recently created /var/log/dovecot.log Here my logrotate config for Dovecot: /var/log/dovecot.log { su root syslog rotate 7 missingok copytruncate create 666 root syslog sharedscripts postrotate doveadm log reopen endscript } Doveadm should reopen it but no, still writes to old log file. Not sure, maybe it's someone else, not dovecot, writing to the log file? And here the versions: # 2.2.33.2 (d6601f4ec): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.21 (92477967) # OS: Linux 4.14.49-rh65-20180612025235.xenU.x86_64 x86_64 Ubuntu 18.04 LTS How can we investigate best? Or is there a mistake in the above logrotate config? - Michael -- Binary Kitchen Michael Heuberger 1/33 Parrish Road Sandringham Auckland 1025 (New Zealand) Mobile (text only) ... +64 21 261 89 81 Email ................ michael(a)binarykitchen.com Website .............. http://www.binarykitchen.com
