[Dovecot] Courier to dovecot migration issue
by Rami Rami 21 Oct '09

21 Oct '09

Hello, I am trying to migrate users form courier to dovecot 1.2.6. The main configuration parameters are as follows : ------------------------------------------------------------------------------------------------------ # 1.2.6: /usr/local/etc/dovecot.conf Warning: fd limit 1024 is lower than what Dovecot can use under full load (more than 2304).

This issue is resolved by replacing : maildir:~/Maildir:INDEX=/tmp/QUOTA/index/%u:CONTROL=/tmp/QUOTA/control/%u with maildir:~/Maildir any idea on the reason of these duplicates or workarounds to prevent them while keeping indexes in /tmp. Thank you.

[Dovecot] testing needed
by Timo Sirainen 21 Oct '09

21 Oct '09

Can someone find an OS where the attached program doesn't work? It should print "success". So far tested for success: Linux 2.6, Solaris 10, FreeBSD 7.2, OpenBSD 4.2.

Good afternoon again I was thinking about the Dovecot upgrading so i´m doing this in the next hours. in the other hand here i show you the dovecot-ldap.conf file I think it has just the necessary options to bind the LDAP server. /hosts = ********* base = ou=People,o=*****,o=****** ldap_version = 3 auth_bind = yes auth_bind_userdn = uid=%u,ou=People,o=******,o=****** /About the dovecot.conf should I use some login options as /login_process_per_connection = yes /or /login_processes_count = 1/? For now thanks so much for the help i´ll inform about the new version installation Juan Felipe Estrada dovecot-request(a)dovecot.org escribió: > Send dovecot mailing list submissions to > dovecot(a)dovecot.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://dovecot.org/cgi-bin/mailman/listinfo/dovecot > or, via email, send a message with subject or body 'help' to > dovecot-request(a)dovecot.org > > You can reach the person managing the list at > dovecot-owner(a)dovecot.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of dovecot digest..." > > > Today's Topics: > > 1.

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

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.

@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] 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.
