[Dovecot] Signal 11 with dovecot-lda
by Jim Dishaw 19 May '14

19 May '14

dovecot version: 2.2.13 NetBSD 5.1 on an amd64 architecture Based on the log file, I think this problem first manifested itself when I upgrade from 2.2.9 to 2.2.12. I tried to go back to 2.2.9, but I would have had to rollback some of the other dependencies. I built 2.2.13 and the problem still exists. Mail gets successfully delivered, but the sender get a non-delivery message. I've hacked a temporary workaround to prevent the non-delivery from being sent by having the bounce service run discard instead of bounce. Logfile excerpt: May 18 04:37:07 chaos postfix/smtp[27935]: 39F8B2134F: to=<XXXX(a)YYYY.ZZZ>, relay=127.0.0.1[127.0.0.1]:10024, delay=21, delays=1.9/0.13/0.69/18, dsn=2.0.0, status=sent (250 2.0.0 from MTA(smtp:[127.0.0.1]:10025): 250 2.0.0 Ok: queued as 0538621350) May 18 04:37:07 chaos postfix/qmgr[19537]: 39F8B2134F: removed May 18 04:37:07 chaos dovecot: lda(XXXX(a)YYYY.ZZZ): msgid=<MAILSM200e8021240fd744d9d8094cd0c3e82dfc2@MAILSM200>: saved mail to INBOX May 18 04:37:07 chaos postfix/pipe[12775]: 0538621350: to=<XXXX(a)YYYY.ZZZ>, relay=dovecot, delay=0.54, delays=0.07/0.3/0/0.18, dsn=5.3.0, status=bounced (Command died with signal 11: "/usr/pkg/libexec/dovecot/dovecot-lda") May 18 04:37:07 chaos postfix/cleanup[2233]: 88C0221353: message-id=<20140518043707.88C0221353(a)chaos.dishaw.org> May 18 04:37:07 chaos postfix/bounce[18857]: 0538621350: sender non-delivery notification: 88C0221353 May 18 04:37:07 chaos postfix/qmgr[19537]: 88C0221353: from=<>, size=14448, nrcpt=1 (queue active) May 18 04:37:07 chaos postfix/qmgr[19537]: 0538621350: removed May 18 04:37:08 chaos postfix/smtp[20299]: 88C0221353: to=<AAAA(a)BBBB.CCC>,relay=site.careerbuilder.com[208.82.4.130]:25, delay=0.89, delays=0.03/0.03/0.25/0.58, dsn=2.6.0, status=sent (250 2.6.0 message received) May 18 04:37:08 chaos postfix/qmgr[19537]: 88C0221353: removed Backtrace: #0 0x00007f7ffc907270 in ??

[Dovecot] RFE: please add Return-Path: to sieve sent mail headers
by Maciej Uhlig 18 May '14

18 May '14

May I ask to add Return-Path: some meaningful header line to sieve sent mail headers in vacation message? Now the header line isn't generated at all and the effect is as follows: on receiving MTA: 2014-05-09T15:04:32+02:00 host/ip postfix/qmgr[2408]: 41F2F6024E: from=<>, size=900, nrcpt=1 (queue active) in received mail body: Return-Path: <> Would be nice to get: Return-Path: <user@domain> Copy of From: header line could be sufficient. Thanks. MU

[Dovecot] antispam plugin doesn't recognize spam folder
by Paul DiSciascio 18 May '14

18 May '14

After a recent upgrade to dovecot 2.2.9 (caused by an ubuntu upgrade to 14.04), the antispam plugin has stopped recognizing my spam folders as spam. I see the plugin initializes properly, but when moving a message, the mailbox_is_spam() function always returns 0. The version of dovecot-antispam that ships with ubuntu is 2.0+20130822-2build1. I also compiled the latest version in the git repository (last update 9/12/2013) and had the same results. This worked fine prior to the upgrade, with dovecot version 2.0.19 and dovecot-antispam version 2.0+20120225-2. Here are the logs from initialization: May 18 07:48:45 lebeau imap: antispam: plugin initialising (2.0-7-gabdad24) May 18 07:48:45 lebeau imap: antispam: verbose debug enabled May 18 07:48:45 lebeau imap: antispam: "SPAM" is exact match spam folder May 18 07:48:45 lebeau imap: antispam: "Spam" is exact match spam folder May 18 07:48:45 lebeau imap: antispam: "Junk" is exact match spam folder May 18 07:48:45 lebeau imap: antispam: no unsure folders May 18 07:48:45 lebeau imap: antispam: "trash" is exact match trash folder May 18 07:48:45 lebeau imap: antispam: "Trash" is exact match trash folder May 18 07:48:45 lebeau imap: antispam: "Deleted Items" is exact match trash folder May 18 07:48:45 lebeau imap: antispam: "Deleted Messages" is exact match trash folder May 18 07:48:45 lebeau imap: antispam: dspam binary set to /usr/bin/dspam May 18 07:48:45 lebeau imap: antispam: dspam extra arg --user May 18 07:48:45 lebeau imap: antispam: dspam extra arg thenut(a)bytemonkey.net May 18 07:48:45 lebeau imap: antispam: signature header line is "X-DSPAM-Signature" And then from the message move: May 18 07:50:06 lebeau imap: antispam: mailbox_is_unsure(SPAM): 0 May 18 07:50:06 lebeau imap: antispam: mailbox_is_trash(INBOX): 0 May 18 07:50:06 lebeau imap: antispam: mailbox_is_trash(SPAM): 0 May 18 07:50:06 lebeau imap: antispam: mail copy: from trash: 0, to trash: 0 May 18 07:50:06 lebeau imap: antispam: mailbox_is_spam(INBOX): 0 May 18 07:50:06 lebeau imap: antispam: mailbox_is_spam(SPAM): 0 May 18 07:50:06 lebeau imap: antispam: mailbox_is_unsure(INBOX): 0 May 18 07:50:06 lebeau imap: antispam: mail copy: src spam: 0, dst spam: 0, src unsure: 0 Clearly mailbox_is_spam(SPAM) should return 1. The other folders I have designated as spam (Junk and Spam) produce the same results. ~Paul

[Dovecot] Feature Request doveadm acl command
by Thomas Leuxner 18 May '14

18 May '14

I have switched to global ACLs for public namespaces which eases their administration greately. Now while running housekeeping scripts (e.g. expunge old mails/archive mails etc.) this requires temporary overriding the global ACLs with mailbox specifix ACLs to expunge mails. The scripts would then revoke the temporary changes (delete flags) and the global ACL would take precedence again. Ideally I would want to get rid of the 'dovecot-acl' file after the scripts ran so the global ACL kicks in. There seems to be no interface command to purge 'dovecot-acl' files so this is handled by the scripts for now: [...] # Get actual path of dovecot-acl file and remove it as it is handled by global ACL acl_path=$(doveadm acl debug -u $mailbox_owner "$source_mailbox_base/$1" 2>&1 | sed -n "s/$.*$$debug_acl_mailbox_path//p") [ -f $acl_path/dovecot-acl ] && rm $acl_path/dovecot-acl It would be nice if purging a specific dovecot-acl would be handled by doveadm to avoid custom-scripting.

[Dovecot] User not found when using shadow for passdb
by John J. Stimson III 17 May '14

17 May '14

I am getting "user unknown" when trying to connect to the dovecot server using IMAP. The client gets an authentication failed message and does not download mail. The host system uses shadow passwords in /etc/shadow. I would like to use the same passwords for IMAP sessions, so I have set the passdb driver to shadow. The system is Slackware, which does not use PAM. Here is the dovecot version and configuration output: # dovecot -n # 2.1.17: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 3.6.5 i686 Slackware 13.1.0 auth_debug_passwords = yes auth_verbose = yes namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = blocking=no driver = shadow } service auth { unix_listener auth-userdb { user = root } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = blocking=no driver = passwd } Here are the dovecot auth_passwd_debug level log messages when the client tries to connect: May 2 09:05:07 harlie dovecot: auth: Debug: Loading modules from directory: /usr/local/lib/dovecot/auth May 2 09:05:07 harlie dovecot: auth: Debug: auth client connected (pid=22181) May 2 09:05:07 harlie dovecot: auth: Debug: client in: AUTH^I1^IPLAIN^Iservice=imap^Isecured^Isession=ABCDEFGHIJKLMNOP^Ilip=96.229.223.7^Irip=10.0.0.181^Ilport=993^Irport=51898^Iresp=zxywvutsrqponmlkji== May 2 09:05:07 harlie dovecot: auth: Debug: shadow(john,10.0.0.181,<ABCDEFGHIJKLMNOP>): lookup May 2 09:05:07 harlie dovecot: auth: shadow(john,10.0.0.181,<ABCDEFGHIJKLMNOP>): unknown user May 2 09:05:09 harlie dovecot: auth: Debug: client passdb out: FAIL^I1^Iuser=john May 2 09:05:09 harlie dovecot: imap-login: Disconnected (auth failed, 1 attempts in 2 secs): user=<john>, method=PLAIN, rip=10.0.0.181, lip=96.229.223.7, TLS, session=<ABCDEFGHIJKLMNOP> The user john is a real account on the host machine and has entries in both /etc/passwd and /etc/shadow.

[Dovecot] Problems setting up extprograms in combination with crm114
by Patrick Winnertz 16 May '14

16 May '14

Hello, I've troubles to configure sieve correctly to call the mailreaver script in order to parse mails for spam. I've the task to migrate a existing procmail setup to a sieve setup, and to keep the mail filtering step within sieve. I've added in /usr/lib/dovecot/sieve-filters/ a script called "mailreaver", which contains basically only one line - calling the right mailreaver.crm script: exec /usr/share/crm114/mailreaver.crm -u ~/.crm114 This script is then called in the sieve file using "filter "mailreaver". Indeed the script is invoked for every mail, however the signature is appended at the very end of the mail, not at the end of the header. Invoking the /usr/lib/dovecot/sieve-filters/mailreaver manually this way: cat test-email | /usr/lib/dovecot/sieve-filters/mailreaver or this way: /usr/lib/dovecot/sieve-filters/mailreaver < test-email results in both cases in a correct formatted way, so I don't know what is going wrong here. Adding a | tee /tmp/test-output resulted in the complete mail in /tmp/test-output, as I first thought that maybe the headers are not piped into the script - but this seems to be not the case obviously. Does anybody has a clue, as this seems not to be related to crm114 (as it obviously works on cmd), but to the way sieve calls this script. Or it would help to understand how the external filtering program is called - maybe my assumptions are wrong here (or I've simply missunderstood the documentation available online). Greetings Winnie

Tried this but it doesn't work. Says Unknown setting: password passdb { driver = static pass word = secret } The real file doesn't have a space in pass word. What am I doing wrong? Thanks in advance.
