Released Pigeonhole v0.4.11.rc1 for Dovecot v2.2.21
by Stephan Bosch 04 Jan '16

04 Jan '16

Hello Dovecot users, First, a happy new year to you all! :) In the last few weeks I got quite a few bug reports. I also found a few things myself. Some of the bugs are quite annoying, so a new release is necessary. First, I release RC1. If all is well, I'll release the definitive Pigeonhole v0.4.11 within the next few days. Changelog v0.4.11: - Sieve mime extension: Fixed the header :mime :anychild test to work properly outside a foreverypart loop. - Several fixes in message body part handling: - Fixed assert failure occurring when text extraction is attempted on an empty or broken text part. - Fixed assert failure in handling of body parts that are converted to text. - Fixed header unfolding for (mime) headers parsed from any mime part. - Fixed trimming for (mime) headers parsed from any mime part. - Fixed erroneous changes to the message part tree structure performed when re-parsing the message. - LDA Sieve plugin: Fixed logging of actions; sometimes the configured log format was not followed. - LDA Sieve plugin: Fixed bug in error handling of script storage initialization. - Sieve Extprograms plugin: Ignored ENOTCONN error in shutdown(fd, SHUT_WR) call. - Fixed duplication of discard actions in the script result. Each discard was counted as a separate action, which means that action limit would be crossed too early. - Made sure that quota errors never get logged as errors in syslog. - Fixed handling of implicit keep for a partially executed transaction that yielded a temporary failure. - Fixed handling of global errors. If master and user error handler were identical, in some cases the log message could be lost. - Fixed AIX compile issue in message body parser. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.11… http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.11… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release candidate and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

Howto get information about quota used
by Макаров Денис 03 Jan '16

03 Jan '16

Hello guys! I have Dovecot server (version: 2.2.9) with quota and imap_quota plugins. I wanna know how to get information about quota used of current email. I can do this with IMAP client like Thunderbird, but how I can do it on server? doveconf -n | grep quota mail_plugins = quota, antispam quota = maildir:User quota_exceeded_message = Message quota_rule = *:storage=100M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u quota_warning3 = -storage=100%% quota-warning below %u service quota-warning { executable = /usr/local/bin/quota-warning.sh mail_plugins = quota imap_quota mail_plugins = quota sieve For each mailboxes I use quota limits from MySQL. -- С уважением, *Макаров Денис* *почта*: makarovdenis11(a)gmail.com <mailto:makarovdenis11@gmail.com> Best regards, *Makarov Denis* *email*: makarovdenis11(a)gmail.com <mailto:makarovdenis11@gmail.com>

SASL binds
by Brendan Kearney 01 Jan '16

01 Jan '16

i am looking to get SASL binds working in Dovecot for userdb lookups, and i am not sure what i might be doing wrong. Dovecot version - 2.2.19 running on Fedora 22. MIT Kerberos and OpenLDAP are being used. my LDAP configs: uris = ldap://server1.bpk2.com ldap://server2.bpk2.com sasl_bind = yes sasl_mech = gssapi sasl_realm = BPK2.COM sasl_authz_id = imap/imap.bpk2.com(a)BPK2.COM base = dc=bpk2,dc=com the above results in the below error logs: Jan 01 13:56:58 mail auth[16747]: GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (No Kerberos credentials available) Jan 01 13:56:58 mail dovecot[16722]: auth-worker(16747): Error: LDAP: binding failed (dn (none)): Local error, SASL(-1): generic failure: GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (No Kerberos credentials available) i am assuming the keytab, /etc/dovecot/dovecot.keytab would be used to bind to the directory, but i am not sure. the auth_krb5_keytab directive is set with the absolute path and keytab name. is there something i am missing, such as a /etc/sasl2/dovecot.conf file? in the directory, i am mapping the Kerberos ID to LDAP user object as such: uid=imap\/(.*).bpk2.com,cn=bpk2.com,cn=gssapi,cn=auth uid=mda,ou=processUsers,ou=Users,dc=bpk2,dc=com if i change the sasl_authz_id to uid=mda,ou=processUsers,ou=Users,dc=bpk2,dc=com, and restart dovecot, i still get the same error. can anyone shed light on where i am going wrong? thanks in advance, brendan

doveadm expunge no longer works
by Fabian Groffen 31 Dec '15

31 Dec '15

Heya, Just upgraded from 2.2.19 to dovecot-2.2.21 and noticed expunging mail no longer works. # doveadm expunge -u theuser MAILBOX spam all Fatal: expunge: To avoid accidents, each branch in search query must contain something else besides MAILBOX (e.g. just add "all" if you want everything) Clearly, I've already got all in there, so I tried capitalising, etc. Looking at the code, I see expunge_search_args_is_msgset_or_ok apparently is failing. I'm wondering if this function [1] is actually doing what it is supposed to do, since it uses return, instead a var to figure out whether it is ok or not. In my case, just because it finds MAILBOX it returns without looking whether there is any further arguments. Or am I missing the point here (and how should I expunge a folder of mail?) Thanks, Fabian [1] https://github.com/dovecot/core/blob/6971937a6f3e93844dbd43bdbe903628e21a94… -- Fabian Groffen Gentoo on a different level

sieve-filter to script fails with SHUT_WR
by Mark Stover 31 Dec '15

31 Dec '15

Trying to make vnd.dovecot.filter to exchange an email with my script. (I have a vnd.dovecot.pipe script working, so I'm pretty sure it's not the configuration...) I'm passing the email using stdin/stdout and _not_ using sockets. My script receives the email and processes it, but the filter process fails: lda(<username>): Error: shutdown(/usr/local/lib/dovecot-sieve/sieve-filter/CleanAttachments.py, SHUT_WR) failed: Socket is not connected lda(<username>): Error: sieve: 20-filter-incoming: line 15: filter action: failed to execute to program `CleanAttachments.py' Not sure, what I'm doing wrong...

Query regarding migration from Maillenium to Dovecot mail server
by Sirisha R 29 Dec '15

29 Dec '15

Hi, We have few queries regarding dovecot mail server. Our application used to supported maillenium mail server, but soon this server is going to retire. So we are planning to migrate our application mail server to dovecot for which we seek your help. Previously, the mailboxes that our application used to support were under att domain, then the mailboxes were migrated to maillenium mail server, and aliases of the existing att mailboxes were created by maillenium support group, so that any mail sent to the att mailbox automatically gets redirected to maillenium alias mailbox. For instance, for the mailbox abc.att.com, an alias was created as abc(a)maillenium.att.com<mailto:abc@maillenium.att.com>. Maillenium support group provided us mailServerHost, mailServerUsername and mailServerPassword. We seek your help in migrating from Maillenium mail system to Dovecot. Thanks & Regards, R Sirisha This message and the information contained herein is proprietary and confidential and subject to the Amdocs policy statement, you may review at http://www.amdocs.com/email_disclaimer.asp
