[Dovecot] dovecot proxy, imapproxy, perdition . . . or?
by Lorens Kockum 21 Mar '11

21 Mar '11

Hi, I have two load-balanced dovecot servers using a single NFS mount. The version is 1.2.11. I chose this so that if one server goes down the other will take up the load, and if my load is too much for one server I just have to add more identical servers. It works, but I wish to move to SAN storage because the NFS server is exhibiting irregular performance. (I spent a lot of time with tcpdump to check that it wasn't NFS locking problems). Performance is very important to me, not in the sense of many users but in the sense of quick response time, since the main use is as a webmail backend. That means that instead of load-balancing connections between servers I will have to partition users between servers (all on one to begin with) and direct users to the corresponding server. I expected to use perdition, but when reading up on that I found imapproxy, which could be interesting for performance reasons, and also that dovecot has an included proxy, and that its performance is better than perdition. However on http://wiki.dovecot.org/HowTo/ImapProxy the feature "IMAP/POP3 server with proxy feature" is noted as "This model is still a bit unfinished in current code." Is this still true? There's also a general note that "This page was written quite a long time ago and may not match reality anymore" . . .

[Dovecot] questions/problems virtual plugin pop3 leave copies on the server for x days then delete
by Robert Schetterer 21 Mar '11

Hi Timo, i allready asked about this , and did some fixes , but it isnt working yet ,as far i have a setup like namespace default { # type = private separator = / prefix = "" list = yes # hidden = no subscriptions = yes } namespace virtual { # type = private prefix = "virtual/" separator = / location = virtual:/etc/dovecot/virtual:LAYOUT=maildir++:INDEX=~/virtual hidden = yes list = no subscriptions= no } namespace real { # type = private prefix = "RealMails/" separator = / list = no hidden = yes } pop3_enable_last = yes pop3_reuse_xuidl = no pop3_uidl_format = %g pop3_logout_format = top=%t/%p, retr=%r/%b, del=%d/%m, size=%s mail_max_userip_connections = 100 mail_plugins = expire virtual quota mail_log fts fts_squat notify pop3_client_workarounds = outlook-no-nuls oe-ns-eoh RealMails/ RealMails/* -RealMails/Trash -RealMails/Trash/* -RealMails/Sent -RealMails/Sent/* -RealMails/Templates -RealMails/Templates/* -RealMails/Drafts -RealMails/Drafts/* -RealMails/Archives -RealMails/Archives/* unseen normally this works as expected some users want to use leave copies messages on the server for x days then delete via pop3 i tested this with thunderbird and looked into the maildir, it seems that the mails stay in "new" folder of the maildir after i downloaded via pop3 ( i am not sure is this expected ? , i would thought they get to cur ) thunderbird does not download this mails again ( good ), but it doesnt delete them from maildir new ever( bad ) , so the whole leave copy and delete after x days function pop3 is not working i am not quite sure if there is relation to virtual namespaces ( which i like to use in future too ) , but have to renable this feature working any idea? -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] Virtual and system users with public mailboxes
by kshaw＠kendallshaw.com 21 Mar '11

21 Mar '11

Hi, I am running dovecot 1.2.9 and postfix, and I am trying to setup a public mailbox. My thought is that there would be one system user with a sieve script to deliver messages to the public mailbox. And, I would like to give virtual users access to the mailbox. On this list, I read how you can have both system and virtual users by using passdb and static userdbs. But, I don't understand how this can be combined with namespaces, where I specify the location. For all virtual users I had: mail_location = maildir:/var/somewhere/%u/maildir/ I think I need that for virtual users and: maildir:~/Maildir for the system users. namespace private { location = ? # how do I have the location be different for system and virtual users? } namespace public { location = ? # ditto (for the index)? } Kendall

[Dovecot] maildir location
by upen 21 Mar '11

21 Mar '11

Hello, I am trying to use dovecot (v. 2.0.11) and postfix (v. 2.7.3) together. The email server is an ldap client and user's home directories on NFS server are mounted using autofs. As I understand, Maildir performance is better than mbox type, so I'd like to use Maildir instead of mbox. However, when I checked conf.d/10-mail.conf file, there is mail_location = maildir:~/.maildir already configured in it which means user's email will reside in their home directories on the NFS server rather than being on Email server's local storage where plenty of space is available. I anticipate due to NFS there will again be a performance hit . Question : Can I change mail_location for maildir to be somewhere other than ~/.maildir. ( like /var/mail/%u/Maildir, where /var/mail is local storage). There are about 200 ldap users who will be using this email server through squirrel-mail or access them through email clients. By the way, I am confused about one setting in postfix : home_mailbox = .maildir/ in main.cf . Does this really play any role? If so, which parameter should be changed and to what and with what permissions to the new directory. Hope I was able to explain, if not please let me know for more details.. Thanks, U

[Dovecot] Can't disable chroot to 'empty' dir, but need to... how to do it?
by Tim Bessie 21 Mar '11

21 Mar '11

Hello all... I've installed dovecot on my ISP's shell server, and am using SSH tunnelling so that I can retrieve my mbox-format mail from procmail-processed mailboxes on that server (normally I just ssh there and read them locally with pine, but now that I have a phone with an IMAP client, I wanted to be able to read it more easily there). The problem I'm having is, although it's working, whenever dovecot starts up, or I try to log in, it attempts to chroot to /home/mydir/dovecot/var/run/dovecot/empty (where /home/mydir/dovecot is the path to my dovecot installation). I've turned off all chroot'ing in all the config files, but it still seems to want to chroot to that one directory. The message I see in the log is: Mar 19 02:09:43 master: Info: Dovecot v2.0.11 starting up (core dumps disabled) Mar 19 02:09:44 anvil: Fatal: chroot(/home/mydir/dovecot/var/run/dovecot/empty) failed: Operation not permitted Mar 19 02:09:44 master: Error: service(anvil): command startup failed, throttling This doesn't cause a problem accessing my mail, but it DOES seem to wait 60 seconds between attempts at chroot'ing, so logins to the server take that long (until the chroot fails). Is there any way I can disable this? Again, I've followed the instructions and set 'chroot=' (empty) for all services, but that hasn't helped. - Tim

[Dovecot] dovecot authentication Local + MySQL
by PARTH MONGA 20 Mar '11

20 Mar '11

Hi Friends I am facing an issue with dovecot configuration and i am describing it in a nutshell. We have a dovecot setup under ultramonkey load balancer and in loadbalancer we have a check defined for pop service which queries mysqldatabase for a particular user name/password after every 2 minutes to check if service is live or not.. Things are fine till here . Now The catch is if somehow that particular user info(either password or username) is mistakenly changed in mysql database whole of my pop gets down beacuse load balancer cant login and that is a single point of failure in my setup . Now what i want is I want to know if there is any method that i can setup in dovecot to lookup for a user locally first and then go for a remote search for the user( ie in mysql database) So that we get the user searched locally before querying the mysql database Local + mysql database authetication i want to be in parallel with each other. Please show some light on this . Thanks and Regards Parth Monga

[Dovecot] Strange Dovecot Issue
by Scott Hughes 20 Mar '11

20 Mar '11

Greetings, I am trying to copy email from one server to another server using Thunderbird. The old server is a closed source ModusMail server and the new server is a Qmail server running Dovecot 1.2.3 (yes, I realize this is behind the times a bit). My issue is this: Whenever Thunderbird gets to a message that has been forwarded (has the forward flag set) an error is generated from the new server (dovecot) that it does not know how to handle the forward flag. Is this a known issue or is it simply that my version of Dovecot is behind? Thanks, Scott

[Dovecot] Question about "extracting" unwanted e-mails from mdbox

Imagine the following scenario Last Saturday, 3:00 AM a big phishing attack hits our e-mail inboxes. Spamassassin does not mark them as spam, and our 50.000+ users have in their mdbox a very credible phishing attack. What doveadm-fu could I use to delete (or move to spam) that e-mail from each user INBOX (let´s imagine the Subject or a Header is known)? I repeat: already delivered e-mail, how to filter/prune it.

[Dovecot] remove old files

Hello I use the dovecot 2.0.10 server and wonder how to clean up correctly the old mails (especially for spam folder). I use maildir storage, and wonder if deleting files with an rm and file command combinaison would be good or would corrupt indexes files/whatever. for exemple, the spam folder is in ~/.mail/.INBOX.spam/ Thus, can I "cd ~/.mail/.INBOX.spam/ && rm 'files older than 2 months' " or something else ?

[Dovecot] dovecot LDA: "temporary failure"
by David Koski 18 Mar '11

18 Mar '11

This really has me stumped and desperate. I upgraded Debian from 5 to 6 (squeeze) and now Dovecot LDA fails. I have checked permissions and the usual. Postfix SMTP, Dovecot POP3 and Dovecot IMAP work. Having to upgrade MySQL from 5.0 to 5.1 made me question that. Logging is of little help. I have turned on logging for LDA to a separate file. When I try to run the deliver command it returns nothing and appears to do nothing: ~$ cat /etc/hosts | /usr/lib/dovecot/deliver -f root@localhost -d dkoski(a)[domainhidden].com $ ..but then I don't know what to expect.

[Dovecot] Migrating to mdbox
by Chris Wilson 17 Mar '11

17 Mar '11

Hi all, I think it would be a good idea for me to move from mbox to mdbox, as I have 57,000 messages in my inbox, and clients hang for a minute whenever they request a CHECK, or Dovecot feels the need to run one itself. Looking at past threads: http://www.mail-archive.com/dovecot@dovecot.org/msg35212.html http://comments.gmane.org/gmane.mail.imap.dovecot/53936 it seems that the safest way is to run: sudo dsync -v -u chris backup mdbox:/home/chris/mdbox eliminate any errors that it reports, test the new mdbox access temporarily, and then switch my config in Dovecot. Ideally I'd like to do that just for me, without disrupting other users of this server (that I help to admin). This error occurs every time I run dsync, and I understand it, so I've elided it: dsync(chris): Error: open() failed with mbox file /home/chris/mail/admin: Permission denied dsync(chris): Error: Failed to sync mailbox admin: Internal error occurred. Refer to server log for more information.

[Dovecot] SSL Compatibility? SNI vs SAN (Subject Alternative Names) and multiple domains
by Thomas Harold 17 Mar '11

17 Mar '11

Getting ready to redo our mail server setup and I'm trying to wrap my head around the ins and outs and pratfalls involved in SSL, multiple domains, and Dovecot. I've taken a look at: http://wiki2.dovecot.org/SSL/DovecotConfiguration My basic understanding at this point is that: - With SSL for IMAP/POP3, it is limited to one certificate per IP address, because the SSL process starts as soon as the client opens the socket to the IP address. In order to support multiple domains / server names, you have to rely on SAN (Subject Alternative Names) in the server's SSL certificate. - If I use STARTTLS for IMAP/POP3 and Dovecot 2.x, then the SNI process will allow the client to specify that they want to talk to mail server XYZ and Dovecot will hand the correct certificate to the client. However, a lot of devices don't support SNI yet so this is fraught with peril and incompatibilities. So it seems like if I have fewer IP addresses then mail server names, I should stick with a single SSL cert and use SANs. (Wildcard certs are not an option due to the top level domain being different.) How big of an issue is a cert with half a dozen or a dozen SANs attached? Do most mail clients handle that sort of certificate properly in order to access their mailboxes? Reference links: http://www.digicert.com/subject-alternative-name-compatibility.htm

[Dovecot] dict crashes with multiple map definitions
by Birger Brunswiek 17 Mar '11

Hi, I get a crash in dict if I use multiple map sections. Each one of them works fine by their own. I managed to convince dovecot to create dump files to debug this, but I can't figure out how to do the same for dict. How can I do this? Anyway, perhaps someone already know's what's wrong by looking at what I do in the sql dict configuration.

[Dovecot] dovecot 1.2 quota with local users
by iti＠promax.media.pl 17 Mar '11

17 Mar '11

Hello, I got problem with setting quota from mysql for local users. In database are only information with quota. Password are store in passwd/shadow. My database have only simple info like in wiki description. Table created with: CREATE TABLE quota ( username varchar(100) not null, bytes bigint not null default 0, messages integer not null default 0, primary key (username) ); In dovecot.conf like in description is: dict { quotadict = mysql:/etc/dovecot-dict-sql.conf } plugin { # v1.2 + SQL: quota = dict:user::proxy::quotadict # v1.2 + file: quota = dict:user::file:%h/Maildir/dovecot-quota quota_rule = *:storage=10M:messages=1000 } File dovecot-dict-sql.conf has: # v1.2+ only: connect = host=localhost dbname=mails user=sqluser password=sqlpass map { pattern = priv/quota/storage table = quota username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota username_field = username value_field = messages } With corrected values about databasename, user and password. Where should to add information about sql query when autorization is not via myqsl (only shadow/password). There are in description info about additional file with user_query: dovecot-mysql.conf. Can anybody know how it should it look like and where to add it in config?

[Dovecot] inetd config - dovecot doesn't exits
by kjonca＠o2.pl 17 Mar '11

17 Mar '11

Is there any option for dovecot to exit when is unneded? I mostly use dovecot via shell process (ie. something like /usr/sbin/dovecot --exec-mail imap) But sometimes I want to use it remotely via tcp and I run dovecot via inetd. --8<---------------cut here---------------start------------->8--- localhost:imap stream tcp nowait root /usr/sbin/tcpd /usr/lib/dovecot/imap-login --8<---------------cut here---------------end--------------->8--- in inetd.conf works good, but dovecot stays, even if all clients ended their connections. How can I make dovecot to exit after last client disconnects?

[Dovecot] Attachment file size error in SIS
by Daniel L. Miller 17 Mar '11

17 Mar '11

I've got an attachment that triggers a "smaller than expected" error. It was a pdf I received some time ago. I copied the file from the dovecot storage, renamed it to something close to the original name (I don't remember what that was), then created a new mail with this as an attachment and saved it to the server. This created a new file, identical file size to the other - but continues to have the "smaller than expected" error. -- Daniel

[Dovecot] Configuration of LMTP Reject Code
by Petter Urkedal 17 Mar '11

17 Mar '11

Is it possible to change the reject codes from the Dovecot LMTP agent? In particular I would like to change the "550 5.1.1 <...> User doesn't exist." to a temporary failure, since we already validate email addresses on the mail front-end, and such errors are most likely due to a temporary glitch in the user database lookup. We use Postfix on the front-end, which is very configurable in this respect. I don't see a way to override the error code from LMTP, though, but suggestions are welcome.

[Dovecot] Using dovecot with wordpress/phpass passwords?
by Joan 17 Mar '11

17 Mar '11

Good afternoon, I am trying to setup dovecot to authenticate using the userdata from wordpress. It's being a bit mor difficult than I thought. This is the relevant part of the dovecot-sql.conf default_pass_scheme = CRYPT password_query = SELECT user_pass AS password FROM wp_users WHERE user_email='%u'; user_query = SELECT 501 as uid, 501 as gid,'maildir:storage=51200' as quota FROM wp_users WHERE user_email = '%u' I can see that the query is being procecessed according to the logs. Wordpress and others are using phpass to authenticate (http://www.openwall.com/phpass/) it is basically a salted md5 hash. Basically, after the process, a hash like this is obtained. $P$BiWISc3IsqRHxeEjq4VJP1Vi8gy4mg1 (for test123 password) I would like to know if dovecot would be able to read this, otherwise I could still make a custom checkpassword function but that would be non-optimal. Could someone guide me on this? If you need more details just ask. Thanks a lot, joan

[Dovecot] exim and /var/run/dovecot/auth-client permissions
by John Connett 17 Mar '11

17 Mar '11

I am attempting to configure a dovecot 2.0 + exim + fetchmail (demon) combination on openSUSE 11.4, initially with the standard dovecot package (2.0.9-3.4-x86_64) and now with the later server:mail build service package (2.0.11-1.1-x86_64). I followed the instructions in http://wiki2.dovecot.org/HowTo/EximAndDovecotSASL but despite the changes in conf.d/10-master.conf the permissions on /var/run/dovecot/auth-client remain unchanged: $ ls -l /var/run/dovecot/auth-client Srw------- 1 root root 0 Mar 14 13:11 /var/run/dovecot/auth-client $ This is probably the cause of authentication failures from exim. I suspect it is something trivial but haven't yet been able to find the answer.

[Dovecot] Patch proposition to implement a new workaround: tb-lsub-flags
by Bruno Tréguier 12 Mar '11

12 Mar '11

Hi again Timo, As agreed earlier tonight, you'll find as attachments 4 diffs (diff -u) implementing the new workaround "tb-lsub-flags". The 4 impacted files are: ./src/imap/imap-settings.h ./src/imap/imap-settings.c ./src/imap/cmd-list.c ./src/config/all-settings.c Here is the proposed description for the dovecot.conf file: # tb-lsub-flags: # Usually IMAP servers don't bother returning the flags attached # to each mailbox, but Thunderbird presently needs them in order # to correctly process the "folders of folders" case. Please tell me if the patch format is suitable or if you expect something else. Best regards and thanks again for your responsiveness.

[Dovecot] SASL abort causes 5s delay, triggered by UW libc-client
by Arne Nordmark 12 Mar '11

Since upgrding to Debian squeeze, the web mail system (Imp4/Horde3) suffers delays every time a new IMAP connection is needed. Tracing the authentication conversation, we find: 08:45:55.270609: 00000000 AUTHENTICATE GSSAPI 08:45:55.271277: + 08:45:55.271761: * 08:45:55.271782: 00000000 BAD Authentication aborted by client. 08:45:55.271815: 00000001 AUTHENTICATE PLAIN 08:46:00.271008: + and the PLAIN login succeeds. Imp4 is using php5-imap which is using libc-client, and the delays makes the interface so slow to hardly usable. For reasons best known to its authors, libc-client first initiates GSSAPI authentication, then checks if there is a Kerberos ticket it can use (there is none), then realizes its mistake and aborts SASL, and tries PLAIN. At this point dovecot delays for 5000ms. While not defending libs-client's odd behaviour of not checking for tickets first, it has probably done so for a long time, and dovecot from Debian lenny does not delay at this point. I am lost as how to get around this without changing the code. The "nodelay" parameter can not be used with PAM passdb, according to the documentation. I would be inclined to call always call client_auth_failed with nodelay=TRUE in the SASL_SERVER_REPLY_AUTH_ABORTED case.
