[Dovecot] IMAP SPECIAL-USE extension
by Timo Sirainen 07 Dec '11

07 Dec '11

It's implemented now in dovecot-2.1 hg. It also deprecates autocreate plugin (but it still works the old way). The idea is that you can now do e.g.: mailbox Trash { auto = no special_use = \Trash } mailbox Drafts { auto = no special_use = \Drafts } mailbox Sent { auto = subscribe # autocreate, autosubscribe special_use = \Sent } mailbox Spam { auto = create # autocreate, but don't autosubscribe special_use = \Junk } mailbox virtual/All { # if you have a virtual "All messages" mailbox auto = no special_use = \All } The mailbox names require a namespace prefix, so if you use e.g. "INBOX." prefix you'll need to use: mailbox INBOX.Trash { ..etc..

[Dovecot] master user only for sieve
by Jan-Frode Myklebust 07 Dec '11

07 Dec '11

Changes in SOGo is forcing me to define a master user, so that SOGo can disable sieve out-of-office processing on a given date. I'm not too happy about having master users that are allowed to read the users messages, so is it possible to define a master user that can only log in trough manage-sieve? -jf

But for solving the localization problem for special-use folders, it's only half the way. Are there any plans to support RFC5464 SETMETADATA, so individual users can name their "\Trash" folder "Skraldspand" in danish or what ever they prefer? /Peter

[Dovecot] MUAs creating different "Sent" folders
by Ralf Hildebrandt 06 Dec '11

06 Dec '11

While our webmail installation creates "Sent" as a Sent-Items Folder, Apple Mail creates "Sent Messages". Is there a way of "mapping" foldernames e.g. map "Sent Messages" to "Sent" map "Deletes Messages" to "Trash" and so on? -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | http://www.charite.de

[Dovecot] MS Exchange IMAP Proxy
by Terry Carmen 06 Dec '11

06 Dec '11

I need to make the IMAP interface of an Exchange 2000 server available on the net, however I would like to give it a little protection, and believe Dovecot's IMAP proxy might be appropriate. Does anybody have a *really simple* config that would allow IMAP pass-through to a single Exchange server? The examples I've seen all assume some sort of load balancing, which isn't an issue here, so I'd like to eliminate the need for an unnecessary database server. Does Dovecot do any cleanup of the IMAP commands that would be useful in protecting Exchange (from this, http://www.cvedetails.com/cve/CVE-2007-0221/ for example), or am I barking up the wrong tree? If Dovecot isn't helpful for this, can anybody point me to a better resource? Thanks! Terry

[Dovecot] Strange quota problem

I have a strange problems with quota on v2.0.14. We have an ldap user directory, and all users should have a mailQuota defined there.

[Dovecot] Dovecot crash non stop: "uid 0: exited on signal 11"

Hi all, I have an old physical freebsd 6.2 server running Dovecot 1.0.7. I wanted to virtualised it. So, I did a dd from the physical server and then I restored it on then now Virtual Machine.

[Dovecot] Questions about single intance storage
by Maria Arrea 03 Dec '11

03 Dec '11

Hello We are using dovecot 2.0.16 with mdbox+zlib. We are now testing SiS (Single Instance Storage) and I have 5 questions: 1º Is possible to "dedup" existing mdboxes? 2º Are attachments compressed with zlib if mdboxes already use zlib? 3º I have plenty CPU to spare, should I use a low value of mail_attachment_min_size , like 16KB ? 4º Can I "undo" SiS if I have problems? 5º We use bacula to save indexes & mdboxes, and we recover mailboxes using doveadm import when a user "makes a fatal mistake" wiping all her Inbox. If we enable SiS I am not really sure how can we safely restore a user's INBOX if that user has SiS attachments. Thank you for your (great) support. Maria

[Dovecot] lda/sieve ignores quota from ldap
by Jens Meißner 03 Dec '11

03 Dec '11

Hello, I'm using Dovecot 2.0 with Sieve as MDA and Postfix as MTA. The Postfix delivery command is /usr/lib/dovecot/dovecot-lda -f "$SENDER" -a "$RECIPIENT". I have set a default quota with quota_rule = *:storage=1G. Some users should have a larger quota. This is defined in a ldap directory and I have set user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,mailQuota=quota_rule=*:storage=%$. The imap_quota plugin shows the right quota for all users but the lda ignores the quota rule from ldap. If a user is over default quota but not over his ldap defined quota I get the following error message: From: Mail Delivery Subsystem <postmaster@[…]> Your message to <[…]> was automatically rejected: Quota exceeded (mailbox for user is full) The log file shows the following: Nov 30 18:21:17 […] dovecot: lda([…]): Error: sieve: msgid=<20111130172116.7F065A07D@[…]>: failed to store into mailbox 'INBOX': Quota exceeded (mailbox for user is full) Nov 30 18:21:17 […] dovecot: lda([…]): Error: sieve: script /var/mail/[…]/dovecot.sieve failed with unsuccessful implicit keep (user logfile /var/mail/[…]/dovecot.sieve.log may reveal additional details) Nov 30 18:21:17 […] dovecot: lda([…]): msgid=<20111130172116.7F065A07D@[…]>: rejected: Quota exceeded (mailbox for user is full) dovecot.sieve.log: error: msgid=<20111130172116.7F065A07D@[…]>: failed to store into mailbox 'INBOX': Quota exceeded (mailbox for user is full).

[Dovecot] Authentication listener configuration
by Rainer Frey 02 Dec '11

02 Dec '11

Hi, I'm wondering about the authentication listeners that dovecot uses. In many configurations I see: service auth { unix_listener auth-userdb { Does any component of dovecot use this listener internally (lmtp, lda ...) and does that read the config and search for the listener, or is the exact name "auth-userdb" expected? Is this maybe dependent on the userdb? Which ones need it? And if I want to use postfix SMTP auth, should I define a second listener, or just re-configure that default one to postfix's needs? Also, in which cases do I need to define an auth-worker service, and a unix_listener for it?

[Dovecot] LDAP Authentication - Home Directory Creation
by Stephen Bowman 02 Dec '11

02 Dec '11

How does everyone handle this case? Users are authenticated by LDAP, and do not have accounts on the IMAP/dovecot server. When a new user is added to LDAP, the home directory (/home/newuser) needs to be created on the IMAP/dovecot server so dovecot can create the mail directories inside it (/home/newuser/mail/). Obviously I can come up with a few custom solutions, utilizing cron, but I feel like there's a cleaner solution out there. Thanks!

[Dovecot] dovecot-lda quota rule
by Micah Anderson 01 Dec '11

01 Dec '11

I really like the feature where you can define quota rules with percents which trigger off of the default values[0] (so you can set the Trash to allow for 10% more of the user's quota for example). What I would really love in dovecot would be for the ability to configure a quota rule for dovecot-lda. I would like to configure things so we don't bounce emails for users until they are well over quota, the IMAP quota plugin is a really great way to notify people that they are over quota because it fails to write to other folders.... that should be enough to get people's attention that they need to deal with things, but bouncing is harsh. Is there a way to do this now that I haven't seen? thanks! micah 0. http://wiki2.dovecot.org/Quota/Configuration --

[Dovecot] second active directory
by Айдар Камалов 30 Nov '11

30 Nov '11

Hello! There is dovecot authenticating through AD. All is working well, if authentication is just one of AD. But there is another AD, and working with 2 AD's dovecot don't recognizes last AD user's home directory. For example, if user name in the second AD - 1developer and Mail - it-2c(a)zakamye.ru then dovecot creates folder /var/mail/zakamye.ru/1cdeveloper but it should be /var/mail/zakamye.ru/it-2c. What I do wrong?( And, if I change the order of viewing AD, does not work precisely the second AD: passdb ldap-DUSLYK { driver = ldap args = /etc/dovecot/dovecot-DUSLYK.conf } userdb ldap-DUSLYK { driver = ldap args = /etc/dovecot/dovecot-DUSLYK-users.conf } passdb ldap-DUSL-OFFICE { driver = ldap args = /etc/dovecot/dovecot-DUSL-OFFICE.conf } userdb ldap-DUSL-BASE { driver = ldap args = /etc/dovecot/dovecot-DUSL-OFFICE-users.conf } Sorry for my bad english, but maybe you can understand logs and configs: http://pastebin.com/mtk4XsNE -- Айдар А.

[Dovecot] Fault tolerant architecture
by Marcelo Salhab Brogliato 30 Nov '11

30 Nov '11

Hi, I'm new to this list and want your help. I'm the mail admin for some domains in Rio de Janeiro - Brazil. Today we have only one machine running dovecot (imap+pop3) with local mail. We are migrating to two virtual machines in kvm running in separate hosts. Then we have two main problems: - How to share mail files to both dovecots? We've been thinking about NFS using local indexes. Is this a good approach? - How do we have a fault tolerant mail servers? Our first solutions is using two IP addresses in our DNS records. About NFS using local indexes, I'm configuring a test server. But how to configure local indexes when my mail_location comes from sql (userdb_home actually). I'm using dovecot 1.2.9. I guess you already had some of these problems or maybe in another architecture these neither exists. Thanks for any help, Marcelo

[Dovecot] Best setup for performance and fault tolerance
by Donny Brooks 30 Nov '11

30 Nov '11

Hello all. I am in need of some guidance. First a little background. Currently our mail server is on physical hardware (Dell server with 2x 2.8GHz Xeon w/ 4GB ram, raid5 array, single gigabit nic) running on Fedora 11 and postfix-2.5.6-3.fc11.x86_64 with dovecot-1.2.11-3.fc11.x86_64. Mailstore is via Maildir format that was converted from mbox about a year ago. This same machine is also our PDC with samba, Master LDAP, slave MySQL replication, primary DNS, and home server for about 20 users. We have approximately 200 end users that have mailboxes on the server ranging from 1KB to 20GB in size. Total mail store is currently at 300GB. About 75 of the users are currently POP access and their mail will be moved to the server soon and setup as IMAP. This is calculated to add roughly another 150GB of mail for a total of 450GB mail store. Being a state agency we have to keep the mail indefinitely for public record reasons. We use a mixture of Thunderbird as an IMAP client and SOGo for web access. Now to the problem: Recently we have been having super slow access to the mail server. Turns out the load was insanely high partially due to the samba home server portion, which is being moved off as we speak, and the other part is due to people searching their mail. Just yesterday one of our users nearly brought the entire agency to its knees by performing a search on her 8GB of mail via IMAP. Since the server is old in both hardware and software I have been tasked with moving it to newer hardware and a newer OS. We currently have 3 virtual servers running Xen and a SAN. The new setup will be placed in the virtual environment. I will probably run Fedora 16 as the OS but am open to Centos, Fedora, or Ubuntu. Now to the question: What is the best way to setup Dovecot so that it is tuned for performance and high available? We have been running with this single point of failure for years so as long as we are moving the mail server we might as well build in some redundancy. To solve the searching problem I thought of maybe setting up some type of indexing. I do kind of want to break the various services out on to separate virtual machines for a little more fault tolerance, but that is not totally necessary. What do you think of things like iRedmail? I see it's usefulness but the not being able to separate services kind of defeats the purpose, plus I want to setup a high available MySQL cluster and possibly OpenLDAP or 389 cluster so iRedMail may not be the best solution. Sorry for the long email but I am trying to get all the information out there at once so it will help get more directed responses in the shortest amount of time. I look forward to any and all input on this matter -- Donny B MDAH
