[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

[Dovecot] feature request: IMAP passdb prefetch
by Richard Platel 02 Aug '13

02 Aug '13

It'd be useful for us if the IMAP passdb could be used as a prefetch userdb. The remote IMAP server could respond with something like * OK key=value * OK key=value SEQ OK [CAPABILITY ...] Logged in. Or * OK <some JSON key value pairs> SEQ OK [CAPABILITY ...] Logged in. Would anyone else find this useful?

> You should take this discussion off list. Tell me Dem.... which part of my original question was not fit for the list ? It was a perfectly valid technical question relating to Dovecot, and according to the description of the mailing list "This is the main list for requesting help with Dovecot or talking about it in general" So I was "requesting help" with Dovecot, and everyone else is perfectly within their rights to "talk about it".
