Dovecot lifecycle announcement
by Aki Tuomi 03 Aug '18

03 Aug '18

Hi! We are giving the following end of life (EOL) statements: For any version before 2.2, we are not going to be providing any patches or fixes. This has been the case before, but we are now officially declaring them EOL. For 2.2 versions, we are going to provide security and critical bug fixes for 2.2.36 only. If you are using 2.2.x version prior to .36, we will not be providing anything other than critical security fixes. This means that if you are experiencing a problem with Dovecot, we need you to upgrade into latest 2.3 release and reproduce the problem there. If this happens, please file a bug report and we are more than happy to take a look! If you are using a 2.2.x version packaged from an Operating System Vendor, please open a bug against them for fixing it. We do not provide patches or bug fixes against these OS Vendor specific releases. 2.3.x is the current main release, which will receive feature, bug and security patches. We accept bug reports against latest 2.3 version or master version of Dovecot. If you need packages for 2.3, please see https://repo.dovecot.org. Thank you for using Dovecot! Note: Users with a commercial agreement with Open-Xchange (Dovecot Pro) have a separate EOL policy, so this announcement does not apply to those customers. Aki Tuomi Open-Xchange Oy

Debugging rules with Pigeonhole Sieve
by Pete Gonzalez 03 Aug '18

03 Aug '18

I have a lot of rules in my Sieve script. Sometimes an email message ends up in the wrong folder, due to a problem with one of the rules. However, this is very difficult to debug, because I have no idea which rule matched the email. A log file might be helpful, but that wouldn't be readable without shell access to the mail server. This is not a solution that would work for everyday users, who configure their rules via a web page UI. What would be great would be for the Sieve interpreter to append a custom header to each email message after it gets processed. This header would record which Sieve rules matched the email. Does this feature exist already? Or is there a way to accomplish it via the Dovecot server configuration? Thanks!

Managesieve stopped working - Undefined symbol "i_stream_read_memarea"
by Henrik Larsson 02 Aug '18

After upgrading Dovecot to 2.3.2.1 and Pigeonhole to 0.5.2, managesieve stopped working. I'm using FreeBSD ports tree, to build these. Only domains have been modified in below output. A FreeBSD bug report have also been created. But I'm not sure if this is FreeBSD ports related or Dovecot/Pigeonhole related: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=228067 %uname -a FreeBSD 10.4-RELEASE-p9 FreeBSD 10.4-RELEASE-p9 #0: Sat Jul 14 22:38:37 CEST 2018 /usr/obj/usr/src/sys/GENERIC amd64 %pkg version -v dovecot-2.3.2.1 = up-to-date with index dovecot-pigeonhole-0.5.2_2 = up-to-date with index %dmesg -a /usr/local/libexec/dovecot/managesieve: Undefined symbol "i_stream_read_memarea" doveconf: Error: managesieve-login: dump-capability process returned 1 % dovecot -n # 2.3.2.1 (0719df592): /usr/local/etc/dovecot/dovecot.conf # Pigeonhole version 0.5.2 (7704de5e) /usr/local/libexec/dovecot/managesieve: Undefined symbol "i_stream_read_memarea" doveconf: Error: managesieve-login: dump-capability process returned 1 # OS: FreeBSD 10.4-RELEASE-p9 amd64 # Hostname: mail.example.com auth_mechanisms = plain login first_valid_uid = 125 hostname = mail.example.com listen = * log_path = /var/log/dovecot mail_plugins = zlib mail_privileged_group = postfix mail_temp_dir = /var/db/dovecot namespace compat { hidden = yes inbox = no list = no location = prefix = INBOX. separator = . type = private } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox "Sent Items" { special_use = \Sent } mailbox Spam { special_use = \Junk } mailbox Trash { special_use = \Trash } prefix = separator = . type = private } passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { fts = squat fts_squat = partial=4 full=10 sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = postmaster(a)example.com protocols = imap pop3 lmtp sieve service auth-worker { user = $default_internal_user } service auth { unix_listener /home/mail/postfix/private/dovecot-auth { group = postfix mode = 0660 user = postfix } } service lmtp { executable = lmtp -L unix_listener /home/mail/postfix/private/dovecot-lmtp { group = postfix mode = 0660 user = postfix } } ssl_cert = </etc/ssl/example.com-chained.crt ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lmtp { log_path = /var/log/dovecot-deliver mail_plugins = zlib sieve } protocol lda { mail_plugins = zlib sieve } protocol imap { mail_max_userip_connections = 30 mail_plugins = zlib imap_zlib }

Re: LMTP error, mysterious
by Andras Kemeny 02 Aug '18

you mean i should define another, "fallback" userdb service if prefetch doesn't work for some reason? is it the problem that it's a chicken and egg scenario and with LMTP address verification (from postfix) there is no login beforehand so then dovecot needs to consult the userdb once again and having no fallback mechanism, it gives up? i can understand that, but then it would need to be emphasized in either the prefetch document or the lmtp document on the wiki. i've tried it and now it works, thank you ever so much.

[SIEVE] pipe :copy to external program with arguments
by spamvoll＠googlemail.com 02 Aug '18

02 Aug '18

Hi all, quick questions about sieve pipe: I want to pipe spam messages to an external program with additional parameters my spamlearn.sieve script: require ["vnd.dovecot.pipe", "copy", "imapsieve"]; pipe :copy "mybin" ["-h 127.0.0.1:44444" , "markspam"]; I also tried: pipe :copy "mybin" ["-h 127.0.0.1:44444 markspam"]; pipe :copy "mybin" ["-h 127.0.0.1:44444"] ["markspam"]; pipe :copy :args ["-h 127.0.0.1:44444 markspam"] "mybin" ; It never executes correct, it always ends with: Error: sieve: Execution of script /my/path/to/spamlearn.sieve failed So whats the correct syntax ? What works is a single argument: pipe :copy "myscript" ["markspam"]; Dovecot Version 2.3.2.1

Problems with Sieve and vnd.dovecot.pipe
by Haiko Hertes 02 Aug '18

02 Aug '18

Hello all! I have changed my mailserver from spamassasin and procmail to rspamd and sieve. Rspamd is working, but with some sieve script I still have problems. I have created a script to learn spam: haiko@SERVERNAME:~$ sudo cat /var/vmail/sieve/global/learn-spam.sieve require ["vnd.dovecot.pipe", "copy", "imapsieve"]; pipe :copy "rspamd-learn-spam.sh"; If I run sieve to use this script I get this: haiko@SERVERNAME:~$ sudo sieve /var/vmail/sieve/global/learn-spam.sieve sieve: vnd.dovecot.pipe: file not found sieve: can't require vnd.dovecot.pipe Speicherzugriffsfehler I think, my configs are OK: haiko@SERVERNAME:~$ doveconf -n # 2.2.27 (c0f36b0): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.16 (fed8554) # OS: Linux 4.9.0-7-amd64 x86_64 Debian 9.5 auth_debug_passwords = yes auth_mechanisms = plain login PLAIN LOGIN auth_username_format = %Ln debug_log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot.log listen = * log_path = /var/log/dovecot.log mail_gid = postfix mail_location = maildir:~/Maildir mail_privileged_group = postfix mail_uid = postfix managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacati on subaddress comparator-i;ascii-numeric relational regex imap4flags copy includ e variables body enotify environment mailbox date index ihave duplicate mime for everypart extracttext imapsieve namespace inbox { inbox = yes location = mailbox "Deleted Items" { special_use = \Trash } mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Spam { auto = subscribe special_use = \Junk } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = . } passdb { driver = pam } passdb { driver = pam } plugin { imapsieve_mailbox1_before = file:/var/vmail/sieve/global/learn-spam.sieve imapsieve_mailbox1_causes = COPY imapsieve_mailbox1_name = Spam imapsieve_mailbox2_before = file:/var/vmail/sieve/global/learn-ham.sieve imapsieve_mailbox2_causes = COPY imapsieve_mailbox2_from = Spam imapsieve_mailbox2_name = * quota = maildir:User quota quota_exceeded_message = Benutzer %u hat das Speichervolumen überschritten. / User %u has exhausted allowed storage space. sieve = ~/.dovecot.sieve sieve_before = /var/vmail/sieve/global/spam-global.sieve sieve_extensions = +vnd.dovecot.pipe +vnd.dovecot.filter sieve_global_extensions = +vnd.dovecot.pipe +vnd.dovecot.filter sieve_implicit_extensions = +vnd.dovecot.pipe +vnd.dovecot.filter sieve_pipe_bin_dir = /var/vmail/sieve/global sieve_plugins = sieve_imapsieve sieve_extprograms sieve_trace_level = tests sieve_user_log = ~/.dovecot.sieve.log } postmaster_address = postmaster(a)hertes.net protocols = imap lmtp sieve service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = postfix mode = 0660 user = postfix } } service imap-login { inet_listener imaps { address = * } process_min_avail = 1 } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service managesieve-login { inet_listener sieve { port = 4190 } } service managesieve { process_limit = 1024 } service pop3-login { inet_listener pop3s { address = * } } ssl = required ssl_cert = </etc/letsencrypt/live/hertes.net/fullchain.pem ssl_cipher_list = EDH+CAMELLIA:EDH+aRSA:EECDH+aRSA+AESGCM:EECDH+aRSA+SHA256:EECD H:+CAMELLIA128:+AES128:+SSLv3:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!DSS:!

Basic question about file permissions for sieve error log
by J Doe 02 Aug '18

02 Aug '18

Hello, I have an admittedly very basic question, but I am not able to get it to work. I store my global sieve script in: /etc/dovecot. I recently made a mistake in my global sieve script which causes Dovecot to attempt to log the errors in: /etc/dovecot/sieve-global.log In /var/log/dovecot.log I see: Jul 24 15:33:32 lmtp(test(a)example.com): Error: ABVWGAx/V1uKLAAA1B5X9w: sieve: failed to open logfile (LOGGING TO STDERR): open(/etc/dovecot/sieve-global.log) failed: Permission denied (euid=5000(vmail) egid=5000(vmail) missing +w perm: /etc/dovecot, we're not in group 122(dovecot), dir owned by 0:122 mode=0775) …but the group membership shows: $ sudo -u vmail groups vmail dovecot …and I restarted Dovecot, but the same error happens. What am I doing wrong ? Thanks, - J

In the postfis log is goes like this on mail in: Jul 26 10:23:13 edimailsl2 postfix/smtpd[12812]: 41blTs18Bzz40nl: client=unknown[172.0.0.12] Jul 26 10:23:21 edimailsl2 postfix/cleanup[12825]: 41blTs18Bzz40nl: message-id=<> Jul 26 10:23:21 edimailsl2 postfix/qmgr[10666]: 41blTs18Bzz40nl: from=<tk(a)multimed.dk>, size=225, nrcpt=1 (queue active) Jul 26 10:23:21 edimailsl2 postfix/lmtp[12827]: 41blTs18Bzz40nl: to=<test(a)domain.dk>, relay=172.26.248.178[172.26.248.178]:2003, delay=8.6, delays=8.5/0.06/0.01/0.08, dsn=2.0.0, status=sent (250 2.0.0 <test(a)domain.dk> oCuyJ/mEWVvFfwAAbOxY/Q Saved) Jul 26 10:23:21 edimailsl2 postfix/qmgr[10666]: 41blTs18Bzz40nl: removed And the LMTP on the Dovecot server is: Jul 26 10:23:21 vanslmtpsl1 dovecot: lmtp(32709): Connect from 172.0.0.1 Jul 26 10:23:21 vanslmtpsl1 dovecot: lmtp(test@ domain.dk): msgid=unspecified: saved mail to INBOX Jul 26 10:23:21 vanslmtpsl1 dovecot: lmtp(32709): Disconnect from 172.0.0.1: Successful quit How can I make LMTP log the ID it gives postfix (oCuyJ/mEWVvFfwAAbOxY/Q)? So I can relate the logs from the 2 servers.
