[Dovecot] Rotating the dovecot log file
by Jerry 24 Oct '09

24 Oct '09

Using FreeBSD-7.2, I am attempting to configure the system newsyslog utility to rotate the dovecot.log file. I would prefer to use the system utility rather than the one described on the dovecot wiki for rotating the file. Unfortunately, it is not working. This is the error message that is spawned: newsyslog: illegal signal number in config file: /var/log/dovecot.log root:wheel 0666 1 * $M1D0 CJ /var/run/dovecot/master.pid USR1 Does anyone have an idea how to get this to work?

[Dovecot] New error messages

[Dovecot] v2.0.alpha2 released
by Timo Sirainen 23 Oct '09

23 Oct '09

http://dovecot.org/releases/2.0/alpha/dovecot-2.0.alpha2.tar.gz http://dovecot.org/releases/2.0/alpha/dovecot-2.0.alpha2.tar.gz.sig Changes since alpha1: - All debug messages are now logged to debug log (debug_log_path setting, defaults to info_log_path). Patch by Pascal Volk. - Added support for SORT=DISPLAY IMAP extension. - Added doveadm who command for listing currently logged in users. - ssl_ciphers_list: Disable anonymous and export ciphers by default. - mail_chroot can now contain %variables (e.g. /home/%u) - fixed a bad maildir crashing bug - ssl-params is now run with +15 priority when generating the ssl parameters - Redesigned how login processes log in and create imap/pop3 processes. This fixes several settings and some other problems, plus it's now also possible for a single imap/pop3 process to handle multiple connections. If you want to try this, modify master.conf: service imap { # comment out: #service_count = 1 # This should be at least the number of CPUs, maybe more (2-3x?) process_min_avail = 4 # Limit the number of clients a single process can handle. # Disk IO is blocking, so some commands can take a while. client_limit = 5 } It currently doesn't even try to group same user's connections to same process, they'll just go randomly to whichever process manages to accept it first. Some day perhaps there should be a new service in the middle that keeps track of existing connections and forwards new ones to right mail processes. v2.0.beta1 TODO list: - master.conf has to be somehow put into defaults, so doveconf -n doesn't show its contents. an example master.conf would be minimal and show only those settings that admin might want to change (and those would show up in doveconf -n) - verbose_proctitle=yes is now quite useless because of the imap/pop3 process creation change. Probably enable linux-proctitle-hack and start changing the proctitle much more often. For example it could contain the command that's currently being run by user. And login processes could contain how many client connections they currently have. And other processes too something similar.. - change plugin hook design to allow multiple users in same process to run different plugins See alpha1 release announcement for more about these TODO: - v1.x config backwards compatibility - dsync is buggy - config process is slow - tcp-wrappers support

[Dovecot] Capability info in hello message not complete?

Hi, one Fedora user complains about not some troubles after update to dovecot 1.2. He suspects wrong capability information given by dovecot 1.2 In dovecot.conf he uses imap_capability= option. While response to 'A CAPABILITY' respects imap_capability value, the capability info in hello message does not. for imap_capability=IMAP4 IMAP4rev1 ACL NAMESPACE CHILDREN SORT QUOTA THREAD=ORDEREDSUBJECT UNSELECT IDLE STARTTLS AUTH=PLAIN A CAPABILITY response is: * CAPABILITY IMAP4 IMAP4rev1 ACL NAMESPACE CHILDREN SORT QUOTA THREAD=ORDEREDSUBJECT UNSELECT IDLE STARTTLS AUTH=PLAIN but hello message is: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN] Dovecot ready.

[Dovecot] HA Dovecot Config?
by dovecot＠corwyn.net 23 Oct '09

23 Oct '09

Hi! I'm currently running Dovecot 1.1.8 on a HP server using CentOS 5.2 as my IMAP server, receiving mail from postfix, and also using squirrelmail as the frontend. As I look at upgrading the mail server, I'd like to change to a higher availability configuration (where the server can fail and I don't have to reconfig my imap users). For the SMTP that's easy, because I can use multiple MX records, and I can redirect a port forward from one server to another. But IMAP doesn't have the same functionality, because it's the storage that matters. What's the "best" way to do that? Clustered servers using a SAN? NAS? some sort of appliance in front? Suggestions? Thanks! Rick Rick Steeves http://www.sinister.net In reality nothing is more damaging to the adventurous spirit within a man than a secure future - Alexander Supertramp

[Dovecot] Need a little shadow to MySQL conversion help
by Marc Perkel 22 Oct '09

22 Oct '09

Excuse me for being stupid and confused. I'm trying to convert my dovecot install from passwd-file to mysql. I have a single table called "users" that has 3 fields, user_name, domain_name and password. The data came from passwd/shadow files so it uses the same password encryption as the shadow files do. The directory where the email is stored is calculated elsewhere and not stored in the database. The UID and GID are both mail for all virtual users. The user logs in passing the full email address and the password. So - what would be the config for using MySQL? Do I even need a userdb? If so - what would it be? Thanks in advance.

[Dovecot] VZW Blackberry BIS problems?
by B. Cook 22 Oct '09

22 Oct '09

Ever since Columbus day things have been strange with my two dovecot servers, according to my Blackberry users. We do not have a BES just the standard BIS that comes with a personal account. Several people have told me that since that Monday that they get occasional duplicate copies of messages which only appear singularly in their Maildir inboxes. I myself even called VZW and got transferred to RIM themselves where they 'reset' my account; (same as me going into the BIS server and deleting and adding again) only to have the same thing happen; again occasionally.. Below is relevant dovecot info.. -r-xr-xr-x 1 root wheel 164064 Oct 1 17:16 /usr/local/sbin/dovecot (date it was built; prior to any problems.. *whew*) ;) 1 # 1.2.4: /usr/local/etc/dovecot.conf 2 # OS: FreeBSD 7.2-RELEASE-p3 i386 3 ssl_cert_file: /usr/local/etc/lighttpd/ssl/mail.poughkeepsieschools.org.pem 4 ssl_key_file: /usr/local/etc/lighttpd/ssl/mail.poughkeepsieschools.org.pem 5 disable_plaintext_auth: no 6 verbose_ssl: yes 7 login_dir: /var/run/dovecot/login 8 login_executable: /usr/local/libexec/dovecot/imap-login 9 login_greeting: mail.poughkeepsieschools.org OK 10 first_valid_uid: 89 11 last_valid_uid: 89 12 first_valid_gid: 89 13 last_valid_gid: 89 14 maildir_copy_preserve_filename: yes 15 mail_plugins: quota imap_quota 16 imap_client_workarounds: delay-newmail outlook-idle tb-extra-mailbox-sep 17 auth default: 18 mechanisms: plain login 19 user: vpopmail 20 passdb: 21 driver: vpopmail 22 userdb: 23 driver: vpopmail 24 socket: 25 type: listen 26 client: 27 path: /var/run/dovecot/auth-client 28 mode: 438 29 plugin: 30 quota: maildir:User quota 31 expire: Trash 7 Spam 30 Now what does not show here is something that I put in that it looked like it was supposed to help but didn't.. mailbox_idle_check_interval = 30 after looking around at other people complaining about BIS and possible dovecot issues it seemed that that entry was the 'magic' the BIS was missing; except I never had it and never had troubles. I'm assuming this is a BIS issue of some sort, but I can't tell. After looking on the wiki I didn't see anything that says "BIS users look here for tips.. " So I'm assuming there aren't any; I think it should just work with the IMAP server.. Any help would be appreciated as everyone thinks this is 'our problem' and "if we had an exchange server we wouldn't be having these problems.." Thanks in advance..

[Dovecot] Public Folders

[Dovecot] NFS random redirects
by Thomas Hummel 22 Oct '09

22 Oct '09

Hello, Dovecot documentation states that the "random redirects to multiple servers" NFS solution is to be avoided and I'm investigation the actual risks of it and a way to put it to test. I'm running dovecot-1.2.6 with Maildir (indexes, mailboxes and control files are all on NFS) and I'm using procmail instead of deliver as the LDA. 1. Documentation says : "Dovecot locks the maildir while doing modifications to it or while looking for new messages in it" and then mention the "dovecot-uidlist.lock" dotlock file. a) if that file fcntl'ed in addition (i.e. dotlocked + fcntled or just dotlocked) ? b) is that file THE way to lock the Maildir mentionned above or is it just something else used only for updating that particular file (i.e. is Maildir locked in some way + dovecot-uidlist.lock created or just dovecot-uidlist.lock created) ? 2. Documentation says : "NFS caching is a big problem when multiple computers are accessing the same mailbox simultaneously" I guess it's because of the dotlocks files and not fcntl locking ? Is there anything else than dovecot-uidlist which is dotlocked ? If yes, is it dotlocked only or dotlocked and fcntled ? 3. Documentation says : "Dovecot v1.1 flushes NFS caches when needed if you set mail_nfs_storage=yes" How can a program flush the NFS caches ? By which (system) call ? 4. Documentation says : "Besides the NFS cache problems described above, mailbox contents can't be cached as well in the memory either." Is it about in-memory indexes or part of indexes loaded into memory ? 5. How can I torture-test concurrent access to the same mailbox through 2 dovecot servers ? I don't see imaptest.c anymore on http://dovecot.org/tools but I see 2 nfs_test ? Is there some command line options I should use ? 6. when and why can a random redirect to multiple server can cause mailbox corruption ? On flags only or on content as well ?

[Dovecot] deliver+sieve: Destination address (-a) parsing changes
by Frank Behrens 21 Oct '09

21 Oct '09

When I upgraded my old, long running dovecot 1.1 to newer dovecot-1.2.4 + doevecot-sieve- 0.1.12 I observed a change in destination address (-a) parsing. Old behaviour: When Timo introduced this feature (http://www.dovecot.org/list/dovecot/2007-September/025813.html) it was possible to hand over only the detail part. In my sendmail configuration I used "-a +$h", where $h contains the detail part and may be empty. By default sendmail can call the delivery agent with the following information: $u: The recipient user (always set) $h: Detail part, may be empty $g: The sender address (relative to the recipient). New behaviour: The current sieve version needs a complete address with local- and domain-part. Otherwise we get a warning like deliver(user): sieve: envelope recipient address 'user' is unparseable. The problem is, that the domain part is not always available, e.g. for local delivered emails. This is the main problem, although the setup could be simplified if deliver would accept the old syntax. I'm going to make modifications to sendmail to be able to have all address information available, but this will not solve the problem with missing domain. Now comes my question: Is it better to enhance the address parsing in sieve plugin or should I use a wrapper around deliver? The latter is not very difficult, but introduces an additional process (that may fail). Regards, Frank -- Frank Behrens, Osterwieck, Germany PGP-key 0x5B7C47ED on public servers available.

I want to set expire plugin only for some domains in the same way I set autocreate plugin. vchkpw-wrapper.sh #!/bin/bash DOMAIN=`echo $VPOPUSER|sed s/^.*@//` echo $USER > /tmp/autocreate echo $DOMAIN >> /tmp/autocreate if [ "$DOMAIN" = "operaciones.qnet.com.pe" ]; then export USERDB_AUTOCREATE=INBOX.Spam export USERDB_AUTOSUBSCRIBE=INBOX.Spam export USERDB_EXPIRE="INBOX.Spam 1 INBOX.Spam.* 1" export USERDB_EXPIRE_DICT="proxy::expire" export EXTRA="USERDB_AUTOCREATE USERDB_AUTOSUBSCRIBE USERDB_EXPIRE USERDB_EXPIRE_DICT" set > /tmp/environment fi unset USER exec $* Record the right information in the database but when you run /usr/local/sbin/dovecot --exec-mail ext /usr/local/libexec/dovecot/expire-tool --test Displays the following message Fatal: expire and expire_altmove settings not set You told me it was to migrate to Dovecot 1.2.6 with support for userdb chkpassword to use the following configuration: userdb: driver: prefetch userdb: driver: checkpassword args: /usr/local/bin/userdb.sh My problem is that I have no idea how to create the userdb.sh Please could help in the creation of this script?

[Dovecot] Question about IMAP IDLE (and Palm Pre)
by Ingo Thierack 20 Oct '09

Hello, i try to understand, how it works (IDLE). Try to get it successfully work with my new Palm Pre ;-) which looks like to have a lot issues wir imap... so i'll blame not dovecot for the issues. Sent a mail, from googlemail. processed by dovecot ad 12:11. what me now confusing, is, that there in the out-log is nothing visible, I expected, to see there was sent an notification, there was a new mail. Do i miss something? After arounde 15 minutes the Palm sent a "DONE" and reconnect. then the messages was received.

[Dovecot] Unknown setting: driver
by Rodolfo González González 20 Oct '09

20 Oct '09

Hi, the conversion from courier was done without problems, but now I have a problem with my auth config. I followed the sql example included in the latest dovecot source, and put driver=mysql in dovecot.conf (outside any section), and now I get: --- Error: Error in configuration file /usr/local/etc/dovecot.conf line 50: Unknown setting: driver Fatal: Invalid configuration in /usr/local/etc/dovecot.conf Starting DovecotError: Error in configuration file /usr/local/etc/dovecot.conf line 50: Unknown setting: driver Fatal: Invalid configuration in /usr/local/etc/dovecot.conf --- So I'm lost... what's wrong? if I followed the example :o Then, another question: I had to go back to courier so my users still can work, but I already created the files using the migration script: do I need to rerun the migration script? or what do I need to do when I manage to fix the error above and run dovecot? Thanks.

[Dovecot] clarify 'type', 'executable' & 'path' in 2.0 master.conf?
by PGNet Dev 19 Oct '09

19 Oct '09

@2.0's master.conf, there's, e.g., service config { type= config executable =config unix_listener { path = config mode = 0666 } } can someone please explain function/usage for the 'type', 'executable' & 'path' fields? and, for any file paths, are the presumed to be _relative_ to the dovecot executable? in $PATH? can they accept full/absolute paths? thanks.

[Dovecot] Can't use string ("0") as a HASH ref while "strict refs" in use at /usr/local/sbin/courier-dovecot-migrate.pl line 300.

I use courier-imap 4.6.0, access using pop3 causes no problems. Any hint on what's wrong is appreciated, thanks. Salut, Rodolfo.

[Dovecot] Dovecot deliver with AD LDAP userdb
by Mark Schaub 19 Oct '09

19 Oct '09

Good Afternoon, I have my virtual users stored in an Active Directory database. As far as mail info goes the 2 important fields are: mail (their primary email address) and otherMailbox (a multivalue attribute containing their mail aliases). Right now all email addresses belong in the same domain and there are no immediate plans to change this. If I use Postfix to do the lookups and delivery only using Dovecot for passdb Pam driver and a static userdb then everything delivers fine to mail and otherMailbox addresses. I have been working on switching over to Dovecot's deliver process in order to integrate sieve capability. I have configured userdb ldap and passdb ldap in Dovecot and have set up master and client sockets. Before I describe my problem let me show you my configuration (as I think the dovecot-ldap.conf in particular needs to be explained). Here are the important parts of dovecot.conf: auth default { socket listen { master { path = /usr/var/run/dovecot/auth-master mode = 0666 user = vmail group = vmail } client { path = /var/spool/postfix/private/auth mode = 0666 user = postfix group = postfix } } passdb ldap { args = /etc/dovecot-ldap.conf } userdb ldap { # Path for LDAP configuration file, see doc/dovecot-ldap-example.conf args = /etc/dovecot-ldap.conf } and my dovecot -n: lda: postmaster_address: postmaster(a)sau24.org mail_plugins: sieve auth default: mechanisms: plain login debug: yes passdb: driver: ldap args: /etc/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot-ldap.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 438 user: postfix group: postfix master: path: /usr/var/run/dovecot/auth-master mode: 438 user: vmail group: vmail plugin: sieve: ~/.dovecot.sieve sieve_dir: ~/sieve sieve_storage: ~/sieve Further, here is my dovecot-ldap.conf: hosts = delldb.sau24.org:3268 base = dc=sau24, dc=org ldap_version = 3 dn = cn=Mail User,cn=Users,dc=sau24,dc=org dnpass = secret auth_bind = yes scope = subtree user_attrs = sAMAccountName=home=/home/vmail/%$,=uid=501,=gid=501 pass_attrs = sAMAccountName=user user_filter = (&(objectclass=person)(|(sAMAccountName=%n)(mail=%n@sau24.org)(otherMailbox=%n@sau24.org))) pass_filter = (&(objectclass=person)(|(sAMAccountName=%n)(mail=%n@sau24.org)(othermailbox=%n@sau24.org))) Now, you'll notice that the user_filter and pass_filter have the domain statically placed after the mail and othermailbox attributes. This reason for this is that this ldap configuration is used for both authentication purposes and local delivery, so its not always being passed the domain info (for authentication it gets the users IP address). Since all my users are on the same domain I can statically set this here. This setup authenticates users to imap and pop (users use their sAMAccountName as their username when they log in), and pulls their correct home directory. Checking mail is not a problem at all. Further, this setup will deliver mail correctly to mail addressed to the value in the "mail" attribute. The problem seems to be in the otherMailbox attribute, it cannot lookup the users sAMAccountName based off of the otherMailbox field. Here is what it looks like in the logs for mail sent to my "mail" attribute (mark.schaub(a)sau24.org) Oct 14 12:36:19 auth(default): Info: master in: USER 1 mark.schaub(a)sau24.org service=deliver Oct 14 12:36:19 auth(default): Info: ldap(mark.schaub(a)sau24.org): user search: base=dc=sau24, dc=org scope=subtree filter=(&(objectclass=user)(|(sAMAccountName=mark.schaub)(mail=mark.schaub@sau24.org)(otherMailbox=mark.schaub@sau24.org))) fields=sAMAccountName Oct 14 12:36:19 auth(default): Info: ldap(mark.schaub(a)sau24.org): result: sAMAccountName(home=/home/vmail/%$)=/home/vmail/mschaub Oct 14 12:36:19 auth(default): Info: master out: USER 1 mark.schaub(a)sau24.org home=/home/vmail/mschaub uid=501 gid=501 Oct 14 12:36:19 deliver(mark.schaub(a)sau24.org): Info: sieve: msgid=<6b71e3a70910140936v4e8cd6fdwd847a1721a9d9786(a)mail.gmail.com>: stored mail into mailbox 'INBOX' But this is what I get when I try to send to an address listed in my otherMailbox field (tech(a)sau24.org) Oct 14 12:30:58 auth(default): Info: master in: USER 1 tech(a)sau24.org service=deliver Oct 14 12:30:58 auth(default): Info: ldap(tech(a)sau24.org): user search: base=dc=sau24, dc=org scope=subtree filter=(&(objectclass=user)(|(sAMAccountName=tech)(mail=tech@sau24.org)(otherMailbox=tech@sau24.org))) fields=sAMAccountName Oct 14 12:30:58 auth(default): Info: ldap(tech(a)sau24.org): Unknown user Oct 14 12:30:58 auth(default): Info: master out: NOTFOUND 1 As a test I tried modifying my dovecot-ldap.conf to use different fields instead of otherMailbox. Sending to some of those attributes worked, others didnt. I could use the "sn" and "givenName" attributes, but "postalCode" and "title" would give the same error as otherMailbox. My question is this: is there something wrong with my configuration or can Dovecot only query certain fields in the user_attr string? Thanks, ~ Mark

[Dovecot] Released Sieve v0.1.13 for Dovecot v1.2.6
by Stephan Bosch 19 Oct '09

19 Oct '09

Hello Dovecot users, After about a month of silence, I finally release a new version of Pigeonhole Sieve. This release fixes problems in the multiscript support and improves the body extension further towards RFC compliance. The body extension still needs work, however, since some content types still give erroneous results. Changelog Sieve v0.1.13: + Body extension: implemented proper handling of the :raw transform and added various new tests to the test suite. However, :content "multipart" and :content "message/rfc822" are still not working. + Fixed race condition occuring when multiple instances are saving the same binary (patch by Timo Sirainen). + Test suite: added support for testing multiscript execution. - Made compiler more lenient towars missing CRLF at the end of the script in a hash comment. - Body extension: don't give SKIP_BODY_BLOCK flag to message parser, we want the body! (patch by Timo Sirainen). - Fixed handling of implicit side effects for multiscript execution. - Fixed bugs in multiscript support; subsequent keep actions were not always merged correctly and implicit side effects were not always handled correctly. - Fixed a segfault bug in the sieve-test tool occuring when compile fails. - Fixed segfault bug in action procesing. It was triggered while merging side effects in duplicate actions. - Fixed bug in the Sieve plugin that caused it to try to stat() a NULL path, yielding a 'Bad address' error. The release is available as follows: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.13.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.13.tar.gz.sig Refer to http://pigeonhole.dovecot.org for more information. Have fun testing the new release and don't hesitate to notify me when there are problems. Releases for Dovecot v2.0 are still under development... Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] migrate courier to dovecot script - questions about directory structure
by Ross 17 Oct '09

17 Oct '09

Hi all, Im in the process of moving about 7000 users across from courier to dovecot. Both Maildir setups. The migration script works a treat, but I need a slight change to it. Couriers directory structure looks ike this: /home/vmail/<domain.com.au>/<username>/cur/ /home/vmail/<domain.com.au>/<username>/new/ /home/vmail/<domain.com.au>/<username>/tmp/ /home/vmail/<domain.com.au>/<username>/maildirsize /home/vmail/<domain.com.au>/<username>/courier* etc.. Dovecot looks like this: /home/vmail/<domain.com.au>/<username>/Maildir/cur/ /home/vmail/<domain.com.au>/<username>/Maildir/new/ /home/vmail/<domain.com.au>/<username>/Maildir/tmp/ So the issue is, there is an additional Maildir directory in the structure. Now the migration script works fine, however when the migration is completed, I have to manually add the Maildir directory into the structure, which is going to take a little too long :) Is there something in the script that can add this ? Is there a way to perhaps use the script to add the Maildir part ? My initial plan was to copy the entire /home/vmail/<domain.com.au>/* across to the dovecot server and run the migration script. However, without the Maildir directory in the structure it won't work. Has anyone run into this issue ? How did you solve it ? -- Regards Ross fatboy:/tmp# dovecot --version 1.0.15 fatboy:/tmp# dovecot -n # 1.0.15: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_privileged_group: mail mail_location: maildir:/var/vmail/%Ld/%Ln/Maildir mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv namespace: type: private separator: . prefix: INBOX. inbox: yes auth default: mechanisms: plain login passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: static args: uid=5000 gid=5000 home=/var/vmail/%d/%n allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail plugin: quota: maildir:storage=51200

Re: [Dovecot] Dovecot deliver with AD LDAP userdb [SOLVED]
by Mark Schaub 16 Oct '09

16 Oct '09

> Then there's something different what Dovecot and ldapsearch does. They > have the same dn, dnpass, neither uses tls, same base, deref, scope? > I figured it out, there certainly is something different! The AuthDatabase/LDAP documentation on the Dovecot Wiki says "When connecting to AD, use port 3268". Port 3268 is used for Global Catalog searching. By default the Active Directory Global Catalog wouldn't include attributes like otherMailbox, but would include mail and sn. The solution here would be to either use port 389 and search the domain like ldapsearch or to add the otherMailbox attribute (or any others I want to search on) to the global catalog. It might be worth updating the wiki to mention the reasoning behind using port 3268 and the implications it can cause. Thanks for the help!

[Dovecot] Sendmail and Dovecot Delivery to Virtual Users
by Philipp Hunold 16 Oct '09

16 Oct '09

I'm new to dovecot and sendmail and my server doesn't forward mails to 'dovecot deliver' at all. I was reading http://wiki.dovecot.org/LDA/Sendmail and this http://www.dovecot.org/list/dovecot/2009-June/040353.html from the mailling list but I could figure it out myself. I someone could point me into the right direction. I'm confused with the config for LDA. Basically what I want is every message coming in go to 'deliver' except if there's no dovecot user of course. I'm using 'local_procmail' feature right now, but I tried to comile the dovecot Mailer also. Anyway the dovecot 'deliver' itself works fine. But I cannot receiving emails or messages don't go anywhere. All the debugging I do with telnet right now. first I got 'User Unknown' errors in the maillog so I thought I just missing an alias/virtuser entry. So I create one and forward those to procmail. But now the messages don't go anywhere and the status is sent and I don't seem them in the /var/log/dovecot-deliver.log either, so they are stuck in the middle somewhere. Oct 16 14:26:26 sendmail[29939]: n9GIQQAh029939: to=|/usr/bin/procmail, ctladdr=<mail.address> (8/0), delay=00:00:00, xdelay=00:00:00, mailer=prog, pri=31420, dsn=2.0.0, stat=Sent I don't seem to understand how the message get to dovecot's 'deliver' from sendmail. Some questions I have which may help to solve the problem myself: - how can I tell the LDA to lookup dovecot users too? to it would accept it? - do I need aliases therefore for each dovecot users? - What would the alias look like or is this the wrong way to do it? "test.user: |/usr/bin/procmail" ? - what's the procmail recipe which would work for maildir:/home/vmail/%u mail_location?

[Dovecot] Sieve question
by CJ Keist 16 Oct '09

16 Oct '09

If there is a separate sieve mailing list let me know. But have question if someone else has done this or not. Right now I have web form people use to setup their vacation replies using Sieve (1.1.6). The form alows them to set what they want their reply address to be, whether to send the reply once, weekly or bi-weekly. I would like to setup another option to let them set the date in which to de-active the vacation replies automatically. Right now they have to remember to log back into the form to turn off the vacation reply. Has anyone set something like this up? -- C. J.

If the mailbox is large, it may take time to re-generate index and put lock on inbox file until it's done. However, it should not for smaller mailbox file. Deleting index files did not help. The workaround is rename the mailbox file and copy it to ~/mail folder and let MTA re-create the mailbox. Then let mail client subscribes to the new temp mailbox.

[Dovecot] Dovecot can't find users' sieve files
by Bartosz Fenski aka fEnIo 16 Oct '09

16 Oct '09

Hello. I asked for help on #dovecot but one suggestion I got was setting sieve variable explicitly but unfortunatelly that didn't help. I'm trying to set up sieve to be able to use vacation module. So in the lda section I put: mail_plugins = sieve And in plugins section: sieve = ~/.dovecot.sieve Then I put .dovecot.sieve file in the user's directory.

[Dovecot] Better APPEND performance
by Mike Abbott 16 Oct '09

16 Oct '09

Moving a large number of messages into an IMAP folder on a dovecot server takes quite a long time. This is a popular operation for users migrating their stored messages from their old mail servers through a mail user agent, and it causes a poor first impression of dovecot. I'd like your help to speed this up. I have studied this problem in recent versions, including 1.1.[17-19] and 1.2.[4-6] but I'll focus on 1.2.6, using Maildir++. It seems to be caused by O(n^2) behavior in maintaining the UID list, where n is the number of messages. The client selects a folder then sends thousands of individual APPEND commands (no use of multiappend unfortunately). These cause dovecot to behave as follows: 1. For every other APPENDed message, dovecot appends the new UID to the list quickly. No problem here, this is fast. 2. For every other other APPENDed message, dovecot scans the entire UID list. This is an O(n) algorithm. Since it happens every n/2 times it causes O(n^2) behavior across n consecutive APPENDs. More specifically, 1. APPEND a message to a folder that already contains 30,000 messages. maildir_uidlist_refresh_fast_init() takes the fast path. 2. APPEND a second message to the same folder. maildir_uidlist_refresh_fast_init() takes the slow path: it populates the uidlist->files hash table with all the UIDs, checking for duplicates. At the end of the command maildir_uidlist_deinit() destroys the hash table. Note how this APPEND takes much longer than #1. 3. APPEND a third message to the same folder. Just like #1. 4. APPEND a fourth message to the same folder. Just like #2, and since #2 destroyed the hash, it has to do all that work over again. 5. And so on. What can be done to make maildir_uidlist_refresh_fast_init() choose the fast path more often?

[Dovecot] v2.0.alpha1 released
by Timo Sirainen 16 Oct '09

16 Oct '09

http://dovecot.org/releases/2.0/alpha/dovecot-2.0.alpha1.tar.gz http://dovecot.org/releases/2.0/alpha/dovecot-2.0.alpha1.tar.gz.sig So here's the first alpha version of Dovecot v2.0. There are still a couple of things left to do, but in general it should work for most people. I started using it for my own mails a few days ago and it seems to work without errors. Largest changes since v1.2: * Global ACLs are now looked up using namespace prefixes. For example if you previously had INBOX. namespace prefix and a global ACL for "INBOX.Sent", it's now looked up from "INBOX.Sent" file instead of "Sent" as before. + Redesigned master process. It's now more modular and there is less code running as root. + Configuration supports now per-local/remote ip/network settings. + dsync utility does a two-way mailbox synchronization. + LMTP server and proxying. + Added mdbox (multi-dbox) mail storage backend. + doveadm utility can be used to do all kinds of administration functions. Old dovecotpw and *view utilities now exist in its subcommands. Some things left to do: - Do something about backwards compatibility with v1.x. Either make it read v1.x config files or provide some config conversion utility. - dsync still has some bugs - config process is a bit too slow. config handling in general could use some caching all around. no need to ask configuration for each login unless there are per-remote-ip settings. - some kind of an optional connection policy server could be useful. mainly to finally implement tcp-wrappers support. - mail_uid, mail_gid, mail_chroot settings don't really work now. I think this actually needs a bit larger change, which is probably a good idea in any case: After successfully authenticating, login process needs to get imap/pop3 process executed. Currently this is done by transferring the connection fd to master process, doing userdb lookup and then forking and execing the imap/pop3 process. The new behavior I'm thinking is that after auth, login process would connect to imap/pop3 unix socket in the login/ directory. That would cause master process to fork a new imap/pop3 process (running as root). Login process would send the necessary auth information via the unix socket, possibly transfer also the fd, and imap/pop3 would do the userdb lookup and then drop privileges. This change has some pros: - Master process will no longer temporarily hold some extra fds and use extra memory during auth lookups. If auth process is hanging these could cause problems. - Master process will no longer have any special auth handling code and I can remove type=auth-source and type=auth services. - Of course fixes the mail_* setting issue, because all of this is now done by imap/pop3 process, which knows about these settings. - Creating support for "multiple imap/pop3 post-login connections in a single process" should be pretty easy to implement with this. The imap/pop3 unix socket just needs to be listened by a new process in the middle that keeps track of what imap/pop3 processes exist and can redirect the new connections to those. But also some cons: - drop_priv_before_exec=yes no longer works, unless the uid/gid is hardcoded to the service {} block. - Each imap/pop3 process needs to do a connect() to auth server at startup, adding a bit to the latency.

[Dovecot] "From" address in vacation response on hosted domains with dovecot/postfix/sieve
by Peter Borg 16 Oct '09

16 Oct '09

Hi, I have a working dovecot/postfix/sieve configuration: Ubuntu 8.04 LTS Dovecot 1.2.6 Sieve 0.1.12 Postfix 2.5.1 The server is configured to host multiple domains. All mail delivery, logins and aliases work absolutely perfectly. There's only one weirdness: the 'From' address in vacation responses. If a message is sent to user(a)hosteddomain.com the response comes from user-hosteddomain.com(a)hostingservername.com Obviously it's doing what one would expect in that it's taking the username (user-hosteddomain.com) and appending the local host name (hostingservername.com) This isn't great from the perspective of the hosted user, however, who'd much rather their vacation message was sent from their actual email address. Clearly I can modify this by using a ':from' statement in each relevant sieve file, but I can't rely on users' mail clients to set this (as not all do) and the webmail client in use on the server doesn't set this. I can almost certainly implement some kind of hack using this, but I'd rather not. So how does sieve determine the from address to use if it's not explicitly set in the sieve script for the user, and how can I direct sieve to determine the address differently, preferably with a central configuration option that will apply to all users regardless of domain.....? Regards, Peter.

[Dovecot] Internal server
by Guy 16 Oct '09

16 Oct '09

Hi, I'm looking at doing some testing for a little internal IMAP server. Basically use fetchmail (or some such thing to bring in mail) so users have a local IMAP server to connect to. I'm interested in trying out mdbox, but since I'd have to use dovecot 2.0 with it I thought I'd just check what peoples' experience with 2.0 is like so far? Is it reasonably stable already? Is there also a page showing the differences in config for dbox over maildir? Or is it simply just the change in mail_location and nothing else? Thanks Guy -- Don't just do something...sit there!

[Dovecot] FS Quota broken for delivering BIG message

[Dovecot] Dovecot inactive after an intermittent connection with LDAP

And it still "pending" somehow to wait a response from dovecot. But when ldap is connected to the system, these pending connection (from user) is still pending .... so it makes the "request queue is full". Isn't it?
