[Dovecot] Fileoperations in Maildir – problematic or okay?
by Martin Burgraf 05 Aug '13

05 Aug '13

Hi, I'm wondering: Is it a problem to move and delete files inside a dovecot-managed maildir? For example: I have a folder ~/.maildir/.Sub1.Start/cur and a folder ~/.maildir/.Sub1.Start.old/cur and like to regularly move old mails from the first to the second one. Can you create a cron job saying something like: find ~/.maildir/.Sub1.Start/cur -mtime +5 -exec mv {} ~/.maildir/.Sub1.Start.old/cur \; ? I guess this would be some sort of problem, wouldn't it? IIRC dovecot keeps indexes of the files inside a folder and moving them around like this may confuse the software, am I right? bye Martin

[Dovecot] ./configure dovecot
by LuKreme 03 Aug '13

When I do a ./configure in dovecot (2.2.1) I get this notice (first line): configure: WARNING: you should use --build, --host, --target Then, much later on: checking sys/ucred.h presence... yes configure: WARNING: sys/ucred.h: present but cannot be compiled configure: WARNING: sys/ucred.h: check for missing prerequisite headers? configure: WARNING: sys/ucred.h: see the Autoconf documentation configure: WARNING: sys/ucred.h: section "Present But Cannot Be Compiled" configure: WARNING: sys/ucred.h: proceeding with the compiler's result configure: WARNING: ## ---------------------------------- ## configure: WARNING: ## Report this to dovecot(a)dovecot.org ## configure: WARNING: ## ---------------------------------- ## checking for sys/ucred.h... no at the end I get: configure: creating ./config.status Install prefix . : /usr/local File offsets ... : 64bit I/O polling .... : kqueue I/O notifys .... : kqueue SSL ............ : yes (OpenSSL) GSSAPI ......... : no passdbs ........ : static passwd passwd-file pam checkpassword : -shadow -bsdauth -sia -ldap -sql -vpopmail userdbs ........ : static prefetch passwd passwd-file checkpassword nss : -ldap -sql -vpopmail SQL drivers .... : : -pgsql -mysql -sqlite Full text search : squat : -lucene -solr but there is no makefile created. ./configure --help just runs the configure script again, and none of --build --host or --target have any effect on the errors shown, including the first line error. So I think, ok, fine, I'll grab the latest build (2.2.4). Same result. OK, fine. Let's look at 1.2.17. Same thing, only without the cured.h warning. Still the same error on the first line after ./configure and still no make file. There's no big flashing warning anywhere that I can see that says, "Hey, dummy, this isn't going to work." config.log even ends with a "configure: exit 0" (The system already has dovecot 1.2.17 installed, but I was looking at installing $LATEST). -- May you live in interesting times

[Dovecot] Mail being delivered but MUA showing empty inbox
by Nigel Smith 03 Aug '13

03 Aug '13

Dovecot : 2.0.19 (see config at http://pastebin.com/raw.php?i=KMaQ9Ccc) Postfix : 2.9.6 (see config at http://pastebin.com/raw.php?i=EEeevHfk) I'm trying to get Dovecot and Postfix working on Ubuntu 12.04LTS but am not having much luck. The problem is that although mail gets delivered to the correct place, however pointing a MUA of any description at Dovecot just yields a purportedly empty inbox ! I will first demonstrate correct delivery of mail, then I will show MUA - domain names changed to protect the innocent !

[Dovecot] system_groups_user syntax especially in LDAP
by ray klassen 02 Aug '13

02 Aug '13

so if possible, I'd like an example of how to include system_groups_user in the userdb setup. I'm using ldap, but I could revert to using pam on ldap. There is a ldap query (gleaned from smbldap-tools) that will return a list of groups for a user (&(objectclass=posixGroup)(memberuid=%u)) but I don't know if the ldap driver will handle it but above all I can't figure out how it fits into the dovecot configuration! I'm trying to get Dovecot 2.1.7 on debian wheezy to recognize shared folders that have group ownership.

[Dovecot] Lowering Log Levels Back to Defaults
by Asai 02 Aug '13

02 Aug '13

Greetings, I'm sorry for asking what may be a really obvious question, but I'm having a hard time turning off logging, or at least getting less verbose logging. My dsync logs are about 7 MB daily, and I'm trying to get that switched off. At one point I had it on a lower level of verbosity, and I turned it up for debugging purposes, but now I cannot seem to turn it back down, which is something I did many times before. For example the logs are getting tons of Info level messages. dsync(asai(a)globalchangemusic.org): Info: expunge: box=Trash, uid=61625, msgid=<JIRA.14456.1367259371732.1046.1367259384800@hexagon>, size=9586 In dovecot.conf I have commented out the following include, which used to lower the log levels back to the defaults, but I've upgraded Dovecot recently to 2.2.4 from 2.1 something: #!include conf.d/10-logging.conf I had the default levels raised in that config file. I'm not sure this helps but: [vmail@triata ~]# doveconf -n # 2.2.4: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-194.32.1.el5xen x86_64 CentOS release 5.5 (Final) ext3 auth_mechanisms = plain login mail_home = /vmail/%d/%n/home mail_location = maildir:/vmail/%d/%n mail_plugins = " mail_log notify" managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave namespace { inbox = yes location = prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } plugin { sieve = /vmail/%d/%n/sievescript } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { group = vmail mode = 0660 user = vmail } unix_listener auth-userdb { mode = 0660 user = vmail } user = root } service imap-login { process_min_avail = 3 service_count = 0 vsz_limit = 0 } ssl_cert = </etc/postfix/ssl/triata.globalchangemultimedia.net.pem ssl_key = </etc/postfix/ssl/triata.key userdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } protocol lda { hostname = triata.globalchangemultimedia.net mail_plugin_dir = /usr/lib64/dovecot/ mail_plugins = sieve postmaster_address = postmaster(a)globalchangemultimedia.net } protocol imap { imap_idle_notify_interval = 24 mins mail_max_userip_connections = 60 } -- --Asai

[Dovecot] Custom quota setup
by Richard Platel 02 Aug '13

02 Aug '13

(Dovecot 2.2-ee) We have a weird quota requirement, we have file storage that we manage through our own APIs but want that usage to come out of the user's mail quota. The usage is in a maildirsize like file uncreatively called filestoresize in the user's maildir. In the past we've been doing this by modifying the quota plugin and re-compiling, but it seems like it should be possible to do this via configuration. Is there a way to add a quota setting pointing at this file for additional usage (not limits)? The feature is used infrequently so it would probably be acceptable use the dirsize backend, but I can't figure out how to configure that to point at a certain directory. We pass custom quota rules for each user in our userdb, and use a custom dict proxy program, so that program could read the file and pass a setting at log in time too (if, for example, there was a setting that said "offset the user's quota usage by X amount") Thanks.

We do our own password auth (so we can support custom hash types, etc). I've only a private version of a HTTP-based passdb implemented for a customer. I'm not sure if I should bother adding something to be distributed with Dovecot, since I guess most people would want to modify it in some way anyway. Here's a somewhat modified version of it that hopefully works (at least it compiles): http://dovecot.org/patches/2.2/passdb-openam.c
