[Dovecot] Courier-mta with Dovecot LDA again
by komodo 04 Jan '11

04 Jan '11

Hi all Sorry for repost, but i don't believe that there is noone who know where the problem can be. At least developers should know :-) I have sent this post once, but without answer. I have setup dovecot lda instead of maildrop on my courier server. Delivery is working, sieve plugin too, but i can't figure out why lda can't send emails via sendmail (vacation). I always get error Error: Sendmail process terminated abnormally, exit status 67 And i know why, but i don't know how to setup lda to make it work . Here is .courier file where is redirect to lda. | /usr/libexec/dovecot/deliver -a $RECIPIENT -f $SENDER But the deliver does not pass recipient address to sendmail. Here is some output of strace execve("/usr/libexec/dovecot/deliver", ["/usr/libexec/dovecot/deliver", "-a", "komodo@somedomain", "-f", "someuser@somedomain"], [/* 22 vars */]) = 0 So it's clear that deliver have those variables, but then i can see this execve("/usr/sbin/sendmail", ["/usr/sbin/sendmail", "-i", "-f", "<>", "--", "someuser@somedomain"], [/* 2 vars */] <unfinished ...> And there is empty -f , so here is the problem. How should i setup this to make it work correctly ? Here is my config [root(a)OVZ.mail ~]# dovecot -n # 2.0.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-194.8.1.el5.028stab070.5 x86_64 CentOS release 5.5 (Final) disable_plaintext_auth = no hostname = ovzmail listen = 10.0.10.34 mail_location = maildir:~/Maildir 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 mbox_write_locks = fcntl namespace { inbox = yes location = prefix = INBOX. separator = . type = private } namespace { location = maildir:/home/shared/Maildir prefix = spam_learner. separator = . type = public } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap sieve ssl_cert = </etc/pki/dovecot/certs/server.pem ssl_key = </etc/pki/dovecot/private/server.pem userdb { driver = prefetch } protocol lda { mail_plugins = " sieve" } protocol imap { mail_max_userip_connections = 40 } Many thanks Martin

[Dovecot] Quota ignore subfolders
by Héctor Moreno Blanco 04 Jan '11

04 Jan '11

Hello, We have dovecot 2.0.8 in our servers with Scientific Linux SL release 5.2 (Boron). We want to ignore a mailbox and its child mailboxes. A few weeks ago Timo told me to do this in dovecot.conf, create a new namespace which will be the quotaless namespace and edit the quota: namespace { inbox = yes location = prefix = INBOX. separator = . type = private } namespace { location = maildir:%h/Maildir/carpeta1 prefix = carpeta1. separator = . type = private } plugin { quota = maildir:carpeta1:ns=INBOX. quota_warning = storage=75%% /usr/local/dovecot/bin/quota-warning.sh 75 quota_warning2 = storage=90%% /usr/local/dovecot/bin/quota-warning.sh 90 } We also have passdb and userdb with ldap, with dovecot-ldap.conf: pass_filter = (&(objectClass=qmailUser)(uid=%u)(accountActive=TRUE)) pass_attrs = uid=user,userPassword=password, mailQuotaSize=quota_rule=*:bytes=%$ user_attrs = mailMessageStore=home, mailQuotaSize=quota_rule=*:bytes=%$ user_filter = (&(objectClass=qmailUser)(|(mailAlternateAddress=%u)(mail=%u)(uid=%u))(accountActive=TRUE)) We also tried the easy solution which was to indicate a quota rule in order to ignore the mailbox but with no success. It still get every mailbox to calculate the quota. We set mail_debug=yes to see if there was any error, but everything seemed to be ok. Any suggestions? Thank you very much in advanced.

[Dovecot] Renaming IMAP folders does not affect children
by Johannes Simon 04 Jan '11

04 Jan '11

Hi, we're using dovecot2.0 since August and very happy with it. Just recently Thunderbird users reported problems when renaming folders, and it seems that RFC 2060 (sec. 6.3.5) requires children of a renamed folder to be renamed, too. This however does not happen: Talking IMAP I get: * LIST (\HasChildren) "." "INBOX.NNN1" * LIST (\HasNoChildren) "." "INBOX.NNN1.NNN1a" . rename "INBOX.NNN1" "INBOX.NNN2" * LIST (\HasNoChildren) "." "INBOX.NNN1.NNN1a" * LIST (\HasNoChildren) "." "INBOX.NNN2" There seems to be no problem the filesystem rights, since this works: . rename "INBOX.NNN1.NNN1a" "INBOX.NNN2.NNN1a" * LIST (\HasChildren) "." "INBOX.NNN2" * LIST (\HasNoChildren) "." "INBOX.NNN2.NNN1a" Am I misunderstanding RFC 2060, or is my config wrong (doveconf -n below), or could it be a bug? Cheers, Johannes # 2.0.8 (e030df616faf): /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-openvz-amd64 x86_64 Debian 5.0.7 default_client_limit = 2500 default_process_limit = 600 dotlock_use_excl = yes log_timestamp = "%Y-%m-%d %H:%M:%S " login_greeting = Dovecot 2 ready. mail_fsync = always mail_location = maildir:~/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = autocreate acl 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 mmap_disable = yes namespace { inbox = yes location = prefix = INBOX. separator = . type = private } namespace { list = yes location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u prefix = INBOX.shared.%%u. separator = . subscriptions = no type = shared } passdb { args = session=yes dovecot driver = pam } plugin { acl = vfile acl_shared_dict = file:/etc/dovecot/dict/shared-mailboxes autocreate = INBOX.Trash autocreate2 = INBOX.Junk autocreate3 = INBOX.Sent autocreate4 = INBOX.Junk_old autocreate5 = INBOX.Drafts autosubscribe = INBOX.Trash autosubscribe2 = INBOX.Junk autosubscribe3 = INBOX.Sent autosubscribe4 = INBOX.Drafts sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap pop3 service auth { unix_listener auth-userdb { mode = 0666 } } service dict { user = dovecot } service imap-postlogin { executable = script-login rawlog /etc/dovecot/postlogin.sh user = root } service imap { executable = imap imap-postlogin } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = blocking=yes driver = passwd } protocol imap { mail_max_userip_connections = 50 mail_plugins = autocreate acl imap_acl } protocol pop3 { mail_max_userip_connections = 3 }

[Dovecot] user xxx@mydomain.com doesn't exist
by G.Nau 04 Jan '11

04 Jan '11

new setup of Dovecot 2.0.8 with postfix local users are simply defined as Linux users named xxx, yyy et cetera; IMAP access is fine with that users. Postfix is delivering mails with two domains (to xxx(a)mydomain.com or xxx(a)mydomain.org) and these are rejected by dovecot with 550: user doesn't exist. I've tested the possible usernames with "doveadm user" xxx: okay xxx(a)mydoman.com: "userdb lookup: user xxx(a)mydomain.com doesn't exist" xxx(a)mydoman.org: "userdb lookup: user xxx(a)mydomain.org doesn't exist" Dovecot2 wiki says "Dovecot doesn't care much about domains in usernames" Okay, how to I get dovecot to ignore the domain part (or accept the two defined domains) when mails are delivered from postfix? Or do I have to configure Postfix to strip the domain part before delivering to dovecot? Regards Birte Nauer

[Dovecot] archiving
by PA 03 Jan '11

03 Jan '11

Hi, recently I installed the newest 2.x version of dovecot working with postfixadmin/mysql and it works great, thanks Timo, however I been reading dovecot's mailing list archived messages and haven't run across a good solution for archiving mail with dovecot. There was mention of using rsync but I was looking for incoming mail to be copied to another folder, maybe called archive J, in real time where the user would have only read access to the messages in the archive folder and the expire plug-in would delete messages older then x number of days. Does anyone have an suggestions on how I can implement this, I would also like to hear how some people were implement archiving if they do it differently. Also as far as shared calendars with dovecot what are my options. Sorry if it's a little off topic. Thanks, Paul

[Dovecot] dovecot director terminate ssl ?
by Jan-Frode Myklebust 03 Jan '11

03 Jan '11

I plan on putting two dovecot directors in front of our backend dovecot pop/imap servers, instead of our current haproxy loadbalancing of the connections -- but how do we handle SSL in such a setup. Will all SSL be terminated on the directors automatically, and then proxyed plain text, or is there any configuration needed to achieve this ? Does it matter that the directors are v2.0 while the backends are running v1.2 ? -jf

[Dovecot] Dovecot Quota plugin as Couier quota
by Antonio Perez-Aranda 03 Jan '11

03 Jan '11

I get a similar behavior between dovecot quota plugin and courier quota with the attached patch. When the client change flags, then is forced to recalc. This is because I don't know how to get the changed flags on quota sync method. The courier quota behavior is avoid to count all deleted mails, include "mark as deleted" mails. -- Antonio Pérez-Aranda Alcaide aperezaranda(a)yaco.es Yaco Sistemas S.L. http://www.yaco.es/ C/ Rioja 5, 41001 Sevilla Teléfono +34 954 50 00 57 Fax +34 954 50 09 29

I googled and looked on the dovecot wiki about this client_limit issue, but no success. What's the syntax of the client_limit and where to place it? Into which config file? Inside the global namespace doesn't seems to work (error on dovecot start). -What's the side effect of this setting to my IMAP clients?

[Dovecot] listescape breaks acl plugin
by Jens 02 Jan '11

02 Jan '11

Hi all Without the listescape plugin I see the following things happen: - If I share a mailbox, dovecot-acl-list in Maildir root is updated accordingly. - If I create a subfolder in an already shared mailbox the dovecot-acl file of the parent folder is copied to the new folder and dovecot-acl-list is updated as well. When I activate the "listescape" plugin, this doesn´t happen. Additionally (with listescape enabled), if I create a folder which contains a dot and then share that folder the dovecot-acl-list looses all entries except the first found shared folder without a dot in foldername. I Hope this is not a bug but only a configuration issue. Thanks for any hints in advance and best Regards Jens

[Dovecot] Shared Folders via Symlinking
by Adrian Mardlin 01 Jan '11

01 Jan '11

Hi folks, I'm trying to set up shared folders via symlinking and have come across a problem. I created a folder for one user, then symlinked it to another. I figured that one thing that is likely to happen at some point is that user 2 is going to decide they don't want to look at that folder any more, and will delete it, so I tried this. Much to my relief, it didn't delete the actual mails, just the symlink. However, it did alter the dovecot.index.cache file to indicate that the folder had been removed, and subsequent attempts to select this folder via the primary user resulted in an error, "NO Mailbox was deleted under us". I had to delete dovecot.index.cache to get it working again. Sorry - can't bring myself to call folders mailboxes... ;-) Adrian Mardlin in charge @ The Very Good Email Company t 01442 892641 m 07920 102401 f 01442 808081 w www.verygoodemail.com The content of this email and any attachment is private and may be legally privileged.

[Dovecot] Dovecot 1.2.12 + Postfix + virtual domains: delivering to system users
by Ran Talbott 01 Jan '11

01 Jan '11

As mentioned in my previous posting, I've set up a mailserver for a domain of Winboxen, authenticated through Active Directory. After some struggles, I finally got that working. But I also need to receive emails for a few system users on the mailserver (like postmaster, and a couple of accounts set up for maintaining the system). I thought, based on the way I read the documentation, that I could just add a "userdb passwd", ahead of the "userdb ldap", and deliver would find their home directory maildirs. The virtual users would fail the passwd search, fall through to the LDAP check, and deliver would drop their mail into their maildirs in the /var/mailstore tree. I knew the system users wouldn't be able to login to the IMAP server, but this isn't a concern. Instead, the system users' mail got bounced, after an auth check via the "master" socket (from Postfix, I guess: it's a transient process) whose details don't get logged. And the virtual users' lookups (done by deliver) returned made-up UIDs and GIDs, and maildir locations (/home/<realm>/<username>) completely different from what the LDAP lookup normally returns (/var/mailstore/<username>). So what am I missing here? I managed to work around this by adding the system users to the Postfix virtual.db, but it would be nice to not need to do that. It would also be nice to neable the system users to check email by logging in to the IMAP serve, but I'm reluctant to even try that after the way delivery went completely wonky. Thanks, Ran

[Dovecot] Can doveadm rebuild thread indexes?
by David Warden 30 Dec '10

30 Dec '10

I'm already using "doveadm search" to update my squat fts indexes (dovecot.index.search and dovecot.index.search.uids) but I'd like to also update dovecot's thread index file (dovecot.index.thread) using doveadm. I checked the new wiki and the archives but didn't see any option for this. (I'm running 2.0.8) The alternative (AFAIK) is to write a script that signs in to IMAP and does "thread references UTF-8 ALL" in each folder. As an aside, could the dovecot LDA do any of this work? I'd surely be willing to spend the resources at delivery time to keep those indexes updated if it meant I didn't have to run a cron job to keep them updated. -David Warden

[Dovecot] LDAP binds
by Trever L. Adams 30 Dec '10

30 Dec '10

I am using 2.0.8. Anonymous binds are no longer supported in the environment I am using. I need to change my userdb ldap setup to bind. I believe the ldap server does Kerberos (or can) authentication. My users are authenticating using Kerberos or Kerberos/PAM. This needs to stay in place. Can anyone suggest how I might go about changing my setup to work? My current ldap setup is as follows (the directories, user id, etc are set statically in the configuration elsewhere): tls = yes hosts = MAILSERVER base = dc=middleearth,dc=sapphiresunday,dc=org ldap_version = 3 user_attrs = userPrincipalName=user user_filter = (&(objectClass=person)(|(mail=%u)(sAMAccountName=%u)(userPrincipalName=%u))) # For using doveadm -A: iterate_attrs = userPrincipalName=user iterate_filter = (objectClass=person) Thank you, Trever Adams -- "Seize the day, put no trust in the morrow!" -- Quintus Horatius Flaccus (Horace)

According to this article http://wiki2.dovecot.org/VirtualUsers/Home I think the problem is: mail_location = maildir:/home/vmail/%u and plugin { home = /home/vmail/%u } is the same directory. Is it right? Is the solution to set mail_location = maildir:/home/vmail/mail/%u ? -- Best regards Filip

[Dovecot] IMAP messages not being marked read
by void372＠transientvoid.com 30 Dec '10

30 Dec '10

I recently moved from Fedora 13 to Fedora 14 and consequently to dovecot 2.0.8. Since then, I have observed that messages are not being marked as read in all cases. The general behavior is: 1. Use my mail client to read all unseen messages. All mail folders show no messages unread. 2. Tell mail client to check for new mail. 3. Mail client now says that some folders have new mail (1 or more messages) 4. Clicking on a folder with new mail (say with 6 unread) shows that there are no unread messages. I have observed this behavior using both kmail and squirrelmail so do not believe it is a mail client problem. I have maildir folders to which mail is delivered using procmail recipes directly to the appropriate dovecot folder. In these folders, I notice that the "cur" directory has a matching number of messages that do not have an "S" flag on the end of the file name. For example: # ls .fedora-list/ cur/ dovecot.index.log new/ dovecot.index.cache dovecot-uidlist tmp/ # ls .fedora-list/cur 1293379204.26554_1.nehalem.home.rainbowdreams.com:2,S 1293379206.26571_1.nehalem.home.rainbowdreams.com:2, 1293379207.26581_1.nehalem.home.rainbowdreams.com:2, 1293380106.26744_1.nehalem.home.rainbowdreams.com:2, 1293380106.26748_1.nehalem.home.rainbowdreams.com:2,S 1293381904.26876_1.nehalem.home.rainbowdreams.com:2,S 1293383704.26978_1.nehalem.home.rainbowdreams.com:2,S 1293384604.27005_1.nehalem.home.rainbowdreams.com:2,S 1293385504.27067_1.nehalem.home.rainbowdreams.com:2,S 1293386404.27105_1.nehalem.home.rainbowdreams.com:2,S 1293387305.27158_1.nehalem.home.rainbowdreams.com:2, 1293387305.27166_1.nehalem.home.rainbowdreams.com:2, 1293388204.27193_1.nehalem.home.rainbowdreams.com:2, 1293389105.27234_1.nehalem.home.rainbowdreams.com:2,S 1293390005.27292_1.nehalem.home.rainbowdreams.com:2,S 1293390006.27298_1.nehalem.home.rainbowdreams.com:2,S 1293392706.27400_1.nehalem.home.rainbowdreams.com:2,S 1293392706.27406_1.nehalem.home.rainbowdreams.com:2,S 1293393611.27515_1.nehalem.home.rainbowdreams.com:2,S 1293396304.27673_1.nehalem.home.rainbowdreams.com:2,S 1293396305.27675_1.nehalem.home.rainbowdreams.com:2,S 1293398104.27743_1.nehalem.home.rainbowdreams.com:2,S 1293399003.27966_1.nehalem.home.rainbowdreams.com:2,S I have so far been unable to observe a pattern as to which messages get affected. I made the assumption that perhaps the issue is a conversion issue in my existing maildir folders, but this does not appear to be the case. When I moved the existing directory out of the way and started with a fresh empty directory the issue has come back after a day or two. Unfortunately, my install of Fedora 14 overlaid the partition with Fedora 13, so I cannot confirm the version of dovecot I was using with no issues. (so very glad I use separate disk and partition for the OS!) I can say that all configuration was in one dovecot.conf file, not the multiple conf.d files I see on Fedora 14. Any assistance on what to troubleshoot next is greatly appreciated! The info about my dovecot is shown below. The maildir's are on local LVM/RAID and not remote. Thanks!! # dovecot -n # 2.0.8: /etc/dovecot/dovecot.conf # OS: Linux 2.6.35.10-72.fc14.x86_64 x86_64 Fedora release 14 (Laughlin) ext3 disable_plaintext_auth = no mail_debug = yes mail_location = maildir:/vg02/mail/%u mbox_write_locks = fcntl passdb { driver = pam } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename flag_change append mail_log_fields = uid box msgid size flags } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } # dovecot --version 2.0.8

[Dovecot] Dovecot consulting companies
by Timo Sirainen 30 Dec '10

30 Dec '10

Once in a while someone asks about companies who could help installing / running / etc. their mail server. I don't really know many, so I thought I'd add a wiki page about it. Feel free to add your company on the list if you offer some Dovecot related services. Write also a few words what type of services you offer. http://wiki2.dovecot.org/Consulting I'll add a link there once at least one company is listed. :) Oh and if it's not clear above, I don't mean that the list should contain companies that only offer email accounts (Dovecot or not).

[Dovecot] Reverting from 2.0. to 1.2
by Thomas Hummel 30 Dec '10

30 Dec '10

Hello Timo, I switched this morning from dovecot-1.2.12 to 2.0.8 with a basic setup (high performance login mode, Maildir, everyhing on NFS, one shared but unused namespace). No problem so far except that some Thunderbird users who wouldn't succeed in moving messages from some one folder to another. They'd get a message about some illegal character in the mailboxname (already existing mailbox of course). This is user input so I don't have any details nor sufficient element to consider it a real problem. A Thunderbird restart seems to solve the problem. My questions were : . is there a different handling in the hierarchy separator (internal or advertized for the namespace) ? (I use "/" for both namespaces and "." since in Maildir). . is there a different handling in the non-ASCII mailbox names ? Could it be related ? . if something goes really wrong, is it safe to revert to 1.2.12 ? Maybe some files has non-compatible format (dovecot-uidlist, indexes, ...) ? Thanks. -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] over quota issue

I have a situation where if a user is over quota and sending through postfix I get an error, now this error only happens if the user is over quota, otherwise it works with no problem. However if sending using /usr/local/libexec/dovecot/dovecot-lda it works every time even if overquota, any ideas? I just can't seem to figure this one out.

[Dovecot] Dovecot 1.2.12+Postfix+Active Directory: virtual domain name dropped.
by Ran Talbott 30 Dec '10

30 Dec '10

I have a Windoze-only client who wants to move their mail hosting from godaddy.com hosting to an in-house system. I'm pitching Linux as an alternative to Exchange, and trying to set up a demonstration system for them. While a long-time Linux user, my server admin experience has been in setting up front-ends (mostly Apache-based web interfaces) for the embedded systems I specialize in. The goal is to have an IMAP server where the users don't have Linux IDs, and only need to manually login to the Active Directory domain controller. The client has multiple Internet domains, but all users are in the same Active Directory realm internally. With the help of the how-tos at linuxmail.info, I got the system to the point of being able to authenticate logins for both IMAP and SMTP (usng dovecot-SASL). I tried using PAM first, but it didn't work: running kinit from the command line takes over 90 seconds to get a ticket, and Dovecot timed out after 60 on every login attempt. So I switched to LDAP. Note: I still don't understand why, but authentication through Active Directory didn't work until I changed the querying distinguished name from the "cn=,dc=,dc=" format to "user(a)xxxx.local" format. I have Postfix using dovecot-deliver as the LDA, but I hit a snag: deliver is not putting the domain name in the path to the maildir. I have the active directory query set as: user_filter = (&(objectClass=user)(samaccountname=%n)) user_attrs = =home=/var/mailstore/%d/%n. =uid=501, =gid=501, \ =mail=maildir:/var/mailstore/%d/%n/Maildir/ When I send mail to testing.testing(a)xxxx.xxx (real domain obscured), I see this in mail.log Dec 23 10:49:24 IBMUBUNTU1 dovecot: auth(default): master in: USER#0111#011testing.testing(a)xxxx.xxx#011service=deliver Dec 23 10:49:24 IBMUBUNTU1 dovecot: auth(default): ldap(testing.testing): user search: base=dc=lawley, dc=local scope=subtree filter=(&(objectClass=user) (samaccountname=testing.testing)) fields= Dec 23 10:49:24 IBMUBUNTU1 dovecot: auth(default): ldap(testing.testing): result: objectClass(?unknown?)= cn(?unknown?)= sn(?unknown?)= givenName(?unknown?)= distinguishedName(?unknown?)= instanceType(?unknown?)= whenCreated(?unknown?)= whenChanged(?unknown?)= displayName(?unknown?)= uSNCreated(?unknown?)= uSNChanged(?unknown?)= name(?unknown?)= objectGUID(?unknown?)= userAccountControl(?unknown?)= primaryGroupID(?unknown?)= objectSid(?unknown?)= sAMAccountName(?unknown?)= sAMAccountType(?unknown?)= userPrincipalName(?unknown?)= objectCategory(?unknown?)= Dec 23 10:49:24 IBMUBUNTU1 dovecot: auth(default): master out: USER#0111#011testing.testing#011home=/var/mailstore//testing.testing. =uid=501#011gid=501#011mail=maildir:/var/mailstore//testing.testing/Maildir/ i.e., the domain does not appear in the paths to the home directory or maildir. I found a bug report in the mailing list that looks like it might be the same problem (%d not supported in user_attrs), but the fix it references is for 2.0. Is this a known problem in 1.x? Is there a fix/workaround for it? E.g., could I have Postfix generate the maidir path and pass it to deliver as the "-m" parameter? Thanks, Ran

[Dovecot] Is this really a user agent issue?
by Phil Howard 30 Dec '10

30 Dec '10

I suspect this is a user agent issue, given that Evolution is flaky in so many areas. When I deliver mail to a subfolder/subbox (e.g. the -m option in the deliver command), and Evolution doesn't know of it, yet, creating it fails, and Evolution still can't get to it. Doing things the other way around (create it in Evolution first, then deliver to it) works fine. Seems to be silliness to me. Just wondered if any Dovecot aspects might be involved ... such as the fact that the case is different (e.g. "INBOX" in the filesystem, but "Inbox" in Evolution). -- sHiFt HaPpEnS!

[Dovecot] How to get a working dovecot.conf?
by oddball56 29 Dec '10

29 Dec '10

Hi, I installed openSUSE 11.3 server version, and followed the guidelines from: http://www.howtoforge.com/perfect-server-opensuse-11.3-x86_64-ispconfig-3 Everything works, accept loggin into dovecot. For many days i tried to get logged into dovecot, from localhost, from other pc in the lan, from squirrelmail, not possible. I read manuals on http://wiki.dovecot.org/ and tried to set the passwd db like: auth default { .. passdb passwd-file { args = /etc/passwd.dovecot } .. The "args" were not accepted according to the output from dovecot -n As now i installed dovecot 20, with a fresh dovecot.conf. Ofcourse this was not working, so i 'updated' ISPConfig. Now my dovecot.conf is a mess, and i get errormessages like: Dec 20 21:00:02 AsusTT-sfn6 postfix/smtpd[7073]: fatal: no SASL authentication mechanisms And from dovecot: dovecot.pem missing from /etc/ssl/certs, so no ssl login possible also Now i am checking dovecot -n line by line and this message pops out: mail_plugin_dir: access(/usr/lib/dovecot/modules/imap) failed: No such file or directory passdb { driver = pam } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } furtheron: ssl = no userdb { driver = passwd } userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } it has 64 lines. first and last_valid_uid and gid are set to 5000. In this conf i did not change anything. I would realy appreciate some help, as my only goal was to set up an imap server so i can access my mail from all over the world, and have all mail in 'one' central place, instead of scattered all over many pc's and laptops. The irony is that evrything but this works ;-p tia, for an answer.

[Dovecot] director in large(ish) environments
by Cor Bosman 28 Dec '10

28 Dec '10

Hey all, just wondering who here is running the director service in a larger environment. I just switched our whole production setup to the director and am quite pleased with the result. We're doing a peak of about 25000 tot 30000 concurrent sessions on 3 servers. But ive shut 1 server down a couple of days ago to see what would happen and 2 servers carried the load easily. (16 CPU, 24GB memory servers). If others are using the director on larger setups maybe we can all post when things do or dont work well. Now to see if the solution is better than the problem :) Cor

[Dovecot] Migrate from Maildir to mdbox
by Odhiambo Washington 28 Dec '10

28 Dec '10

Looking at http://wiki2.dovecot.org/Migration/MailFormat, I do not see much on how to do a migration from Maildir to mdbox. That page isn't quite updated it looks. I have several domains (virtual) with the following storage layout: /var/spool/virtual/$domain. So the users have their mail stored as follows: /var/spool/virtual/domain1/$user/Maildir /var/spool/virtual/domain2/$user/Maildir /var/spool/virtual/domain3/$user/Maildir /var/spool/virtual/domainN/$user/Maildir >From the wiki, I am told the steps to take are: 1. Set mail_location=mdbox:~/mdbox 2. Run "doveadm mirror -u username maildir:~/Maildir" The instruction above confuses me because in my situation, I don't have a "username" per se. dovecot-deliver knows how to figure out my usernames and their mail_location settings. How do I derive my "username" when users are virtual, stored in MySQL back end? Again, the right command seems to rely on dsync, not "doveadm mirror". I could manually get all the values for the users for each domain and run: dysnc -u $u -o "mail_location=maildir:/var/spool/virtual/domain1/$u/Maildir" mirror "mdbox:/var/spool/virtual/domain1/$u/mdbox" This is so manual, especially because I have to (if I remember well) create /var/spool/virtual/domain1/$u/mdbox (and have the permissions right) before running dysnc. Is there an easier way out, perhaps?? -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Damn!!

[Dovecot] passwd, gid and uid
by Mauricio Tavares 25 Dec '10

25 Dec '10

I forgot the answer for this: in http://wiki.dovecot.org/AuthDatabase/PasswdFile, we have the passwd file defined as user:password:uid:gid:(gecos):home:(shell):extra_fields What should the uid and gid be associated with? In my setup I told postfix to use Dovecot LDA's deliver, which then is saving files as uid:gid of 1500:1500. How would that affect the uid:gid used in the passwd file? From what I read in the dovecot's wiki, you want them *not* to be anything that has the rights to access the emails. So, does that mean any value for them will do?

[Dovecot] Maildir feature I'd like to see - SSD for newer messages
by Marc Perkel 24 Dec '10

24 Dec '10

SSD drives are very fast but expensive. So I have a crude idea that I'd like to see. May not be practical but would like to get some thoughts on it. Some new SSDs use SATA 3 (6gb/sec) with 355/mb/sec read speeds and 215MB/sec write. Put these in raid 0 and it screams! Can you imagine how fast that would be? What would be nice is if new email were on faster drives with old email being migrated to larger mechanical cheaper storage. Perhaps messages over a month old? From dovecot's perspective it would sort of all look the same but maybe one a week a script would run migrating older messages to slower media. It would also make backups easier. The faster newer messages could be archived hourly. On the weekend after the archiving script was run the older message could be backed up once a week. I'm not sure what it would take to make dovecot seamlessly access email from two different locations or if this is practical. Just wanted to throw the idea out there to see if something sticks.

[Dovecot] Is this an index problem?
by Chris Barnes 23 Dec '10

23 Dec '10

This is my first post to this list/gmane newsgroup, so please be gentle with me.... :-) Here's my situation: I have a user (the "main boss secretary") who uses MS Outlook 2007 as her email client. She has over 46,000 messages in her inbox, with nobody knows how many more in 75+ different folders & subfolders. Surprisingly, her response time wasn't too terrible up until we had to reboot our mail server the other day (actually, restoring the entire server from a backup). Now it takes anywhere from 10 to 60 seconds for her to switch from 1 folder to another. Details: * Server is Debian running Postfix and Dovecot (both the current release). Using Maildir format stored in the user's ~/Maildir folder. * User connects to server via Imaps. Connection is local using gigabit network (ie. it ain't the network). * Yes, we did all the things on the Outlook side -thinking that is where the problem lays. Rebuild the .pst file, had Outlook re-index, compacted the .pst file, etc. So now I'm thinking that maybe I need to just wipe out all of the ~/Mailder/dovecot* files (including all those in sub-directories) and let it all reindex. Which begets 3 questions: (1) will this help? (2) anyone have a shell script that will remove all those dovecot* files from the user's directory AND all the sub-directories? (3) Any other suggestions I might be missing? -- Chris Barnes

[Dovecot] Deliver limit based of number of destination recipients and size of mails, any option to do that?
by Andrés Yacopino 23 Dec '10

23 Dec '10

I have a mail server with postfix, dovecot (1.2.15) and deliver lda (dovecot) with 350 users. I have the problem that in this christmas the employees are sending some big files (mainly powerpoints files) to a lot of recipients, because of that the server get a lot of charge (is a Xeon quad core 5405 with 4GB of Ram), i have four disks in Raid 5 configuration (HP E200 controller, not very fast) Is there any option to limit this type of delivery, the total size of the mails delivered to each user (total recipients * size of mail), in dovecot deliver. I don't want to limit the concurrent delivery more lower than 350 recipients and the max size of the mail we can send is 15M. Thanks a lot, -- Andrés Fernando Yacopino

[Dovecot] trying to make cmusieve happen globally
by Phil Howard 22 Dec '10

22 Dec '10

In Dovecot 1.1.11 cmusieve is apparently integrated in the Ubuntu 9.10 package "dovecot-common" since the files are there. I am wanting to right now just do a very basic test of the setup to see how it runs before doing more sophisticated steps that could obscure any errors or bugs (e.g. unit testing). So I took the following example sieve script from the wiki1 documentation: require "fileinto"; if header :contains "X-Spam-Flag" "YES" { fileinto "spam"; } and recoded it to skip the test and just always do the fileinto step like so: require "fileinto"; fileinto "spamtest"; Then I configured my dovecot.conf file (via dovecot-postfix.conf it really points to) by setting: protocol lda { ... mail_plugins = cmusieve mail_plugin_dir = /usr/lib/dovecot/modules/lda ... } and: plugin { sieve_global_path = /etc/dovecot/sieve-global.d/spam.sieve } I manually compiled /etc/dovecot/sieve-global.d/spam.sieve so there also exists /etc/dovecot/sieve-global.d/spam.sievec in the same directory. Then I restarted both Dovecot and Postfix. Mail is being delivered, but still only to the same place it always has. The filesystem shows these sieve files are not being accessed at all. I've read documents http://wiki1.dovecot.org/LDA/Sieve and http://wiki1.dovecot.org/LDA/Sieve/CMU to come up with this. But it just doesn't seem to be happening. So I guess it is a good thing I've broken my testing down into smaller units. Anything standout that I misinterpreted about the documentation? If not, I can post the whole config files (in case there is a conflict with something else I have done). FYI, I'm only trying to do a global sieve, not per-user sieve scripts. I'll tackle per-user stuff at a later date, after the global is working. -- sHiFt HaPpEnS!

I'm using: - CentOS 5.5 - Kernel 2.6.18-194.26.1.el5 x86_64 - Dovecot 2.0.8 (from source) - Postfix 2.7.2 (from source) - MySQL 5.0.77 (CentOS binary) - Postfixadmin 2.3.2 (from source) - Horde Webmail 1.2.9 - Thunderbird 3.1.7 (from CentOS) I follow this how to: http://wiki2.dovecot.org/HowTo/DovecotLDAPostfixAdminMySQL I was able to send and recieve e-mail via Postfix/Dovecot. I'm having troubles in the quota. As I said, I use Postfixadmin to manage users. When I log in Horde, it says that the quota is unlimited. Thunderbird too. I think it's because of the configuration on Dovecot. Here it's my confs files: ===== dovecot.conf ===== #ssl_cert_file = /etc/pki/dovecot/certs/myserver.example.com.crt #ssl_key_file = /etc/pki/dovecot/private/myserver.example.com.key #ssl_ca_file = /etc/pki/dovecot/certs/ca-bundle.crt #default_login_user = nobody disable_plaintext_auth = no log_path = /var/log/dovecot.log auth_mechanisms = plain login first_valid_uid = 200 last_valid_uid = 200 mail_location = maildir:/var/vmail/%d/%u ssl = no passdb { args = /usr/local/dovecot/etc/dovecot/sql.conf driver = sql } plugin { #acl = vfile:/usr/local/dovecot/etc/dovecot/acls quota = maildir:storage=10240:messages=1000 trash = /usr/local/dovecot/etc/dovecot/trash.conf } service auth { unix_listener auth-userdb { group = vmail mode = 0660 user = vmail } unix_listener auth-master { group = vmail mode = 0660 user = vmail } unix_listener /var/spool/postfix/private/auth { group = vmail mode = 0660 user = postfix } user = dovecot } userdb { args = /usr/local/dovecot/etc/dovecot/sql.conf driver = sql } userdb { driver = prefetch } protocol imap { imap_client_workarounds = delay-newmail mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { mail_plugins = quota postmaster_address = postmaster(a)mydomain.com #log_path = /var/log/dovecot.log #info_log_path = /var/log/dovecot.log } ===== ===== sql.conf ===== driver = mysql connect = host=localhost dbname=postfix user=dovecot password=password user_query = SELECT concat('/var/vmail/', maildir) as home, concat('maildir:/var/vmail/', maildir) as mail, 200 AS uid, 200 AS gid, concat('maildir:storage=', floor(quota/1024)) AS quota FROM mailbox WHERE username = '%u' AND active = '1' ===== ===== mysql ===== mysql> select * from mailbox; +----------------------+------------------------------------+--------------+-----------------------+---------+------------+----------------+---------------------+---------------------+--------+ | username | password | name | maildir | quota | local_part | domain | created | modified | active | +----------------------+------------------------------------+--------------+-----------------------+---------+------------+----------------+---------------------+---------------------+--------+ | teste(a)mydomain.com | $1$bb3d6a71$IF/FORTbdoIqdzBLuSciJ0 | E-mail Teste | mydomain.com/teste/ | 1024000 | teste | mydomain.com | 2010-12-17 10:32:16 | 2010-12-17 11:46:24 | 1 | +----------------------+------------------------------------+--------------+-----------------------+---------+------------+----------------+---------------------+---------------------+--------+ ===== ===== mysql_virtual_mailbox_limit_maps.cf ===== user = postfix password = password hosts = localhost dbname = postfix query = SELECT quota FROM mailbox WHERE username='%s' AND active = '1' ===== I think it's it.

[Dovecot] Managesieve with multiple uid's

Hi, I'm trying to setup a system with dovecot to remove the old courier one, and everything (pop3, imap, lmtp, quotas) but managesieve is working fine.

In this system when I try to connect to the managesieve port using telnet I get no response: $ telnet localhost 4190 Trying 127.0.0.1... Connected to localhost.localdomain (127.0.0.1).

[Dovecot] Restarting dovecot-auth stops authentication
by Attila Nagy 22 Dec '10

22 Dec '10

Hi, The Dovecot wiki states that Dovecot's master restarts all died processes, which is good for availability. But when I kill dovecot/auth (to simulate an error condition which happened on a machine), the authentication fails with: Nov 16 14:32:40 be dovecot: imap: Error: net_connect_unix(auth-master) failed: No such file or directory It seems -albeit it gets restarted- dovecot/auth doesn't re-create its socket file. Before: # ls /var/run/dovecot/ anvil auth-worker doveadm-server anvil-auth-penalty config dovecot.conf auth-client dict empty auth-login director-admin lmtp auth-master director-userdb login auth-userdb dns-client master.pid # ps auwx | grep dovecot/auth dovecot 87455 0.0 0.0 20024 3832 ?? S 2:34PM 0:00.01 dovecot/auth # rm /var/run/dovecot/auth-master; kill 87455 # ps auwx | grep dovecot/auth dovecot 88815 0.0 0.0 20024 3776 ?? S 2:36PM 0:00.01 dovecot/auth # ls /var/run/dovecot/ anvil config dovecot.conf anvil-auth-penalty dict empty auth-client director-admin lmtp auth-login director-userdb login auth-userdb dns-client master.pid auth-worker doveadm-server I've deleted the auth-master socket because if I don't, you can't see that it's not re-created. :) Is this a normal behaviour? I understand that killing dovecot/auth is not, but Dovecot could survive this easily, if recreating and re-using the new socket file would work. And loosing dovecot/auth happens sometimes (I don't yet now why). Thanks,

[Dovecot] Moving email between folders outside of IMAP context
by Phil Howard 21 Dec '10

21 Dec '10

I'd like to run a script from cron that will scan certain mailboxes and move selected mail from one folder (usually INBOX) to another folder. The basic idea is to move previously detected spam based on headers prepended to the mail. Since I am not able to figure out how to get Postfix to invoke deliver with the -m option in these cases, and not in others, this is one idea I have come up with to deal with it. The big (hopefully obvious) complication seems to be getting the indexes updated. Is there a way to move mail this way AND then have the indexes updated to reflect that move (maybe even if regenerating the entire index all over again)? -- sHiFt HaPpEnS!

[Dovecot] Maildir and Solaris UFS acls
by Tom Lieuallen 21 Dec '10

21 Dec '10

I have a centrally located shared imap folder location. We have several maildir folders with different file system permissions. They are for several groups of people who are loosely related for support purposes. All mail gets delivered to queue1 just fine. The files are group writable by group1. Some of the mail gets moved via imap to queue2. Queue2's maildir tree is configured with Solaris UFS acls such that any new files are read/write by group1 or group2. If a new file is created within queue2 anywhere, it has the correct permissions. However, if a message is moved from queue1 to queue2, it retains the permissions that it had within queue1. This is what happens if I use 'mv' within the file system, btw. Is there any way to configure dovecot such that if a person moves or copies a message to another imap folder, it creates a new file instead of doing a link or mv or whatever? If not, no problem; I was just hoping for an elegant solution to my particular problem. :-) queue1 - read/write by group1 queue2 - read/write by group1 & group2 through solaris ACLs BTW, if any file whatsoever in queue2 is not readable by group2, those in group2 cannot read _anything_ in queue2. thanks Tom Lieuallen

Hello, Is there a way to have a Sieve script create a non-existent folder rather than have it deliver messages to INBOX instead? I'm using Dovecot 2.0.8 with Postfix, via LMTP. Thanks!

[Dovecot] Best way to move mail to an archive
by Richard C. Cox 18 Dec '10

18 Dec '10

Hello all...new to dovecot and this list. I have a question that may have been answered before, but I can't find anything yet that addresses it directly. I installed dovecot 2.0.8 (+postfix, fetchmail) on a small server to manage several e-mail accounts. I love this software! So, to back to the question: I'd like to archive e-mail as it ages into a single IMAP archive directory. Ideally, I would like to set up a cron job to search for e-mail in all of my imap directories that older that 'X' days and move it to the archive directory. I know that dovecot wants to manage e-mail movement thru the IMAP interface, so I'm leery of just using ordinary Linux commands to move mail around and bypass the IMAP protocol. Does anybody have any recommendations about dovecot/IMAP safe commands I could use to accomplish this task? Thanks in advance and I apologize for not being more knowledgeable about this subject. Regards, Richard

[Dovecot] Problem with expunge
by Jeff Mitchell 18 Dec '10

18 Dec '10

I'm running Dovecot 2.0.8. The other day I tested doveadm expunge on a test Inbox with a few messages received over the course of a day, and using savedbefore <a few hours>, and it seemed to work. However, today I was testing converting some maildirs over to sdbox, and noticed odd behavior: it's deleting all messages in the specified folder instead of just the ones matching the condition I'm using ("savedbefore 4w"). The command I'm using is "doveadm -Dv expunge -A mailbox Trash savedbefore 4w" Because of the conversion, all of the ctimes for all of the files are actually the same (basically, a few minutes ago), due to the converstion to sdbox from maildir, so I would expect that either it doesn't delete any of them or looks inside at some header of the mail (half of which was received/placed into Trash before 4w ago and half of which wasn't). I definitely don't expect full-on deletion... Any idea what's going on? Thanks, Jeff

Hi, after deciding to use Dovecot 2.0.8 as a postfix LDA using mysql DB I'm running into some issues. I started to follow, http://wiki.dovecot.org/HowTo/DovecotLDAPostfixAdminMySQL but noticed that the auth settings on the config changed, after looking through the dovecot wiki I think I have that issue fixed.

[Dovecot] namespace and list=children inconsistencies
by Holger Mauermann 17 Dec '10

17 Dec '10

Hi, after setting up a new Dovecot server with shared and public namespaces, both with hidden=no and list=children, I see some inconsistency in the folder listing. . NAMESPACE * NAMESPACE (("" "/")) (("Shared/" "/")) (("Public/" "/")) . OK Namespace completed. . LIST "" * * LIST (\HasNoChildren) "/" "INBOX" * LIST (\Noselect \HasChildren) "/" "Shared/user(a)do.main" * LIST (\HasNoChildren) "/" "Shared/user(a)do.main/INBOX" * LIST (\HasChildren) "/" "Public" . OK List completed. . LIST "Shared/" * * LIST (\Noselect \HasChildren) "/" "Shared/user(a)do.main" . OK List completed. . LIST "Public/" * . OK List completed. With LIST "Shared/" the other users INBOX is missing, so with namespace capable clients like Thunderbird it is impossible to see or subscribe this folder. The "Public/" namespace has some subfolders, but only for other acl_groups and I don't have rights to access any of them. So the LIST "Public/" looks good. However, with LIST "" * it is shown without the trailing slash and with \HasChildren where it should be hidden. Here is the relevant doveconf -n output: ... namespace { list = children location = maildir:%%h/Maildir:INDEX=~/shared/%%u prefix = Shared/%%u/ separator = / subscriptions = no type = shared } namespace { list = children location = cydir:/var/spool/imap/public:INDEX=~/public prefix = Public/ separator = / subscriptions = no type = public } ...

[Dovecot] How to avoid "authenticated user not found" - messages when using multiple Ldap userdbs/passdbs?
by Sebastian Urbanneck 16 Dec '10

16 Dec '10

Following: We've got a Dovecot 1.0.10 running on Ubuntu Hardy. Till now we used to have only mail accounts under our own domain, but since we're also a webhoster the people began to ask if there is a possibility to use there own Domains in there mail address. For addressing this we changed our Ldap Tree Structur: users which had been there befor remain in there old subtree, new accounts for Virtual Domains are located below an "vd=<domain>,ou=domains,..." subtree. The main Problem at this: old users are used to login only with their username and password, new users has to login via their complete mail address and their password. This is not going to change in the future so I tried to do this: Using two userdb/passdb - entries, in each case one for the old users and one for the new ones. If a user is not found through the first request the second is tried. If this failed too, the user gets rejected. The Problem with this: when not found during the first try the request logs an "authenticated user ot found" - message, no matter if trying via the second etry is successful. Is there a way to tell dovecot, that the user is not "not found" until __both__ requests failed? Regards Sebastian

[Dovecot] adding servers to director_mail_servers
by Cor Bosman 16 Dec '10

16 Dec '10

Is there a specific order in which one has to add servers to director_mail_servers, Let's say I have 20 loadbalanced director servers (I dont, but for arguments sake). I want to add 5 servers to director_mail_servers. If I do this by restarting each director server 1 by 1 with an updated conf, it seems the 5 new servers dont get added. Or at least I dont get what makes it work eventually. Only after restarting a few times they seem to all want to agree on the new list of servers. Cor

[Dovecot] users's mailboxes = mbox , shared mailboxes = maildir ... is it possible ?
by Frank Bonnet 16 Dec '10

16 Dec '10

Hello I solved my previous SSL problem by reinstalling dovecot2 ... :-) at FreeBSD 8.1 Now I'm using dovecot 2 , cool ... Actually my production mail server runs with MBOX format but reading the dovecot 2 wiki I read shared mailboxes are only working well with Maildir format. As I would like to setup some shared mailboxes, is it possible to have MBOX format for normal users ( UNIX NIS users ) and Maildir format for shared mailboxes to gain access to the per-user \Seen flag Or do I have to convert ALL my server to Maildir format ? Thanks a lot for your help

Hello, What the subject says. I am trying, that is. OK, here's the story. Users very lazy. Don't want to write down their contact details from scratch. Here's what I thought : migrate (export?) contacts from outlook to mozilla thunderbird. Then find a way to make thunderbird "talk" to dovecot, so that the latter can import the contact details from mozilla tb. Any ideas ? Will it work ?

Regarding Dovecot 1.2.x, for maildir, I believe it would be something like this: mail_location = maildir:~/Maildir:INDEX=MEMORY The ":INDEX=MEMORY" disables writing the index files to disk, and as the name implies, I believe, simply keeps indexes in memory. The docs say: "If you really want to, you can also disable the index files completely by appending :INDEX=MEMORY." My read of that is that indexing isn't disabled completely, merely storing the indexes to disk is disables. The indexes are still built and maintained in memory. Timo, is that correct? Also, due to the potential size of the index files (mine alone are 276 MB on an 877 MB mbox), you'll need to do some additional research to see if this is a possibility for you. If using a ramdisk, 100 mail boxen like mine would require ~ 27.6 GB or RAM just for the index files. This would not be logical to do or feasible given the amount of RAM required. I don't know if, or how much, storing them in RAM via :INDEX=MEMORY consumes, as compared to using a ramdisk. The memory consumption may be less or it may be more. Timo should be able to answer this, and give a recommendation as to whether this is even a sane thing to do. -- Stan

[Dovecot] question about snarf plugin in dovecot 2
by Tom Lieuallen 15 Dec '10

15 Dec '10

I'm trying to get the snarf plugin working with dovecot 2.0.7. Specifically, I want to use the UW-IMAP style optional snarfing. I'm looking at the wiki2 documentation. The first question is whether the UW-IMAP optional snarfing will require any changes to the mail_location. The first section suggests (but doesn't specifically state, which I'd propose be clarified) that mail_location be updated to point at ~/mbox for INBOX. However, with the optional snarfing, sometimes inbox will be at /var/mail and for some users, it'll be ~/mbox. What, if anything, do I do to mail_location? Does it matter where (in which config file) the plugin block is placed? I put all of my snarf configuration in 10-mail.conf. It's not working; not snarfing and not reading mail from ~/mbox (how would it, I have yet to tell it to). The following are excerpts from 10-mail.conf mail_location = mbox:~/mail:INBOX=/var/mail/%u:INDEX=/a2/imap-index/%u .... namespace { type = private separator = / prefix = inbox = yes } .... namespace snarf { prefix = /snarf separator = / location = mbox:/private/dovecot/var/run/dovecot/empty:INBOX=/var/mail/%u:INDEX=MEMORY list = no hidden = yes } plugin { snarf = /snarf/INBOX mbox_snarf = ~/mbox } Thank you BTW, the dovecot-2.0.7/docs/wiki appear to be from wiki1, not wiki2... :-) Tom Lieuallen Oregon State University

[Dovecot] After-delivery sieve processing
by Daniel L. Miller 14 Dec '10

14 Dec '10

Is it possible to run sieve against an existing mailbox? My application: I've got a mailbox that stores status messages from multiple sites. It's easier to check up on recent events by having them all in one folder. However, after I've read them, I'd like to have them archived to individual folders per site. I currently have a sieve script that uses "fileinto" to sort the mails - but I'm thinking of removing it from deliver if I can run it as a manual job later. I suppose another method would be to duplicate the mails on delivery into both the main folder and the per site folders, then delete after I've read them - but for whatever reason that strikes me as inelegant. -- Daniel

[Dovecot] Migration from UW-IMAP
by Daniel Senie 14 Dec '10

14 Dec '10

I am attempting to test out dovecot on a server on a separate IP address from the live, functioning UW-IMAP. I am having mixed results with dovecot. An entirely new account that's never been used with UW-IMAP seems to work fine, but that's really not the point of the exercise. If I try changing over an existing account to use dovecot, I get a variety of issues. Testing with Apple Mail.app, if I synchronize the account, the INBOX stops displaying. So off to plan B, and debug via command line commands. I tried connecting to Dovecot. It was able to list the mailboxes for me. I asked for status on INBOX. Sometimes I get an error back in the IMAP stream, sometimes not. Either way, the log shows complaints about creating mail/.imap and below (we use mbox format, plus /var/mail/%u for inbox). I have active namespace compatibility recommended by the Wiki so that clients specifying "mail/" and clients not specifying an imap path both work. With the test account, I proved this functionality is working. At this point I clearly have some issues, and could use some help figuring out what to ask for help with, i.e. how to proceed to debug this without damaging the existing UW-IMAP setup in the process. The goal is to cut over to dovecot once I can be sure it really is working compatibly, but until then I have a large user base and can't blow everything up. And yes, I really, truly have RTFM (i.e. read the Wiki, the troubleshooting pages, the migration pages).

[Dovecot] Incorrect W value after filesystem corruption
by Bob 14 Dec '10

14 Dec '10

Dec 14 00:15:54 vm dovecot: IMAP(####@####): Maildir filename has wrong W value: /var/vmail/#####/####/cur/#########.M###########.??.????.??.??,S=4951,W=5057:2,RSa Dear Dovecot elite, This morning I woke up to find my mail server hard disk controller had gone crazy and decided to corrupt my file system. After over eight passes with the fsck and a new machine I have mostly recovered but this being a personal server the backups were a half-job. So for speed I recovered the mail directly off the bad file system. Most of the data was fine but a few files were corrupt and as a result I have found Dovecot to be a real pain when it comes to handling a wrong W value. I am having to separately look at the mail.log and just systematically remove the W value as a quick work-around. But it seems to me that it would be much easier to have this done by Dovecot when it realises it has this wrong value, especially as Dovecot seems to drop the connection of that user after encountering this problem. Can I suggest as an improvement this scenario is handled better? I saw one posting which said "this should never happen" but clearly it can and I think there could be better handing of it perhaps?

[Dovecot] Courier-mta with Dovecot LDA
by komodo 14 Dec '10

14 Dec '10

Hi all I have setup dovecot lda instead of maildrop on my courier server. Delivery is working, sieve plugin too, but i can't figure out why lda can't send emails via sendmail (vacation). I always get error Error: Sendmail process terminated abnormally, exit status 67 And i know why, but i don't know how to setup lda to make it work . Here is .courier file where is redirect to lda. | /usr/libexec/dovecot/deliver -a $RECIPIENT -f $SENDER But the deliver does not pass recipient address to sendmail. Here is some output of strace execve("/usr/libexec/dovecot/deliver", ["/usr/libexec/dovecot/deliver", "-a", "komodo@somedomain", "-f", "someuser@somedomain"], [/* 22 vars */]) = 0 So it's clear that deliver have those variables, but then i can see this execve("/usr/sbin/sendmail", ["/usr/sbin/sendmail", "-i", "-f", "<>", "--", "someuser@somedomain"], [/* 2 vars */] <unfinished ...> And there is empty -f , so here is the problem. How should i setup this to make it work correctly ? Here is my config [root(a)OVZ.mail ~]# dovecot -n # 2.0.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-194.8.1.el5.028stab070.5 x86_64 CentOS release 5.5 (Final) disable_plaintext_auth = no hostname = ovzmail listen = 10.0.10.34 mail_location = maildir:~/Maildir 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 mbox_write_locks = fcntl namespace { inbox = yes location = prefix = INBOX. separator = . type = private } namespace { location = maildir:/home/shared/Maildir prefix = spam_learner. separator = . type = public } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap sieve ssl_cert = </etc/pki/dovecot/certs/server.pem ssl_key = </etc/pki/dovecot/private/server.pem userdb { driver = prefetch } protocol lda { mail_plugins = " sieve" } protocol imap { mail_max_userip_connections = 40 } Many thanks Martin

Windows Live Mail seems to be a nice IMAP client! Do you have good or bad experiences of WLM with dovecot as server? Thanks!

[Dovecot] FTS and compound searches
by Tony Pyro 13 Dec '10

13 Dec '10

Hello, New subscriber here. I noticed that the FTS index is not used in compound searches. Is this expected? Tested in 2.0.0 and 2.0.8: . search BODY "waldo" * SEARCH . OK Search completed (0.000 secs). . SEARCH CHARSET UTF-8 OR SUBJECT "waldo" FROM "waldo" * SEARCH . OK Search completed (1.768 secs). . SEARCH CHARSET UTF-8 OR SUBJECT "waldo" BODY "waldo" * OK Searched 0% of the mailbox, ETA 9605:25 * OK Searched 4% of the mailbox, ETA 6:39 * OK Searched 6% of the mailbox, ETA 6:58 * OK Searched 8% of the mailbox, ETA 6:54 It's a problem for us because the Afterlogic webmail client does not offer a body-only search. The two search options are From + To + Subject, or "entire messages", which puts together a large OR query: SRCH1069 SEARCH CHARSET UTF-8 OR (OR (OR FROM "waldo" TO "waldo") SUBJECT "waldo") BODY "waldo" I also checked to see whether the header fields are included in the FTS index but it didn't appear so. I got more results from the search "TO gmail.com" than from "BODY gmail.com" plugin { fts = squat } protocol imap { mail_plugins = " fts fts_squat" } Thanks!

[Dovecot] postfix-dovecot-sasl help
by Ted To 13 Dec '10

13 Dec '10

I'm trying to set up SMTP authentication on my server and am getting an authentication failed error. My client is set up to automatically select authentication method and tries CRAM_MD5. The http://wiki.dovecot.org/HowTo/PostfixAndDovecotSASL suggests "passdb pam" and "userdb passwd" -- is it possible to configure sasl authentication using a dovecot.conf like http://pastebin.com/6JWE5jp1? Thanks in advance, Ted To

[Dovecot] Question about "slow" storage but fast cpus, plenty of ram and dovecot
by javierdemiguel＠us.es 13 Dec '10

13 Dec '10

Hello We are using dovecot 1.2.x. In our setup we will have 1200 concurrent imap users (maildirs) and we have 2xraid5 sas 15k diks mounted by iSCSI. The dovecot server (RHEL 5 x64) is a virtual machine in our vmware esx cluster. We want to minimize disk I/O, what config options should we use. We can "exchange" CPU & RAM to minimize disk i/o. Should we change to dovecot 2.0? Maybe mdbox can help us? Maybe ext4 instead of ext3? Any idea is welcome. Regards Javier

[Dovecot] Pigeonhole 0.2.2 - managesieve supports virtual namespaces?
by Tom Talpey 13 Dec '10

13 Dec '10

I got around to trying the 0.2.2 managesieve listener and it's not working for me. As soon as the client authenticates, the connection is closed and the following is logged on the server: > Dec 13 11:48:30 managesieve(xx(a)yy.com): Error: user xx(a)yy.com: Initialization failed: Namespace 'Mobile/': Unknown mail storage driver virtual > Dec 13 11:48:30 managesieve(xx(a)yy.com): Error: Invalid user settings. Refer to server log for more information. I do have such a virtual namespace defined in dovecot.conf, obviously, and it works fine with dovecot 2.0.8. Additionally, the sieve plugin is working fine for lda, dovecot's deliver is executing it perfectly. Do I need to add a setting or plugin to "protocol managesieve" for this? Combed the wiki to no avail.

[Dovecot] extra fields with "passwd" userdb
by Patrick McLean 13 Dec '10

13 Dec '10

Hi, I am planning a migration of ~600 accounts to mdbox (from maildir) and was hoping to do some initial testing of certain account. I am hoping to use extra fields to migrate certain accounts in advance for testing, and I can't find info on setting up extra fields with the "passwd" backend. Is this possible, or will I have to use another approach?

[Dovecot] Feature request
by Nikita Koshikov 13 Dec '10

13 Dec '10

Hello Timo, and all. Preface: From time to time we have problems with thunderbird. The problem is that mail client begin to sync users inbox (or other folder) and this process didn't stop. Last time we have this situation - our monitoring system shows unusual amount of imap traffic send to one of local hosts. This host was - terminal server and 20 users worked with their mailboxes that time. But normal 20 imap session can't fork that amount of traffic (5.2Gb). After measuring local thunderbird's cached mailboxes we find out that one user have local INBOX about 19Gb and size is rising. On server side - this mailbox was 89Mb. And after killing thunderbird in logs appear: Dec 10 17:35:53 IMAP(user@domain 192.168.2.92): Info: Disconnected: Logged out bytes=1133593/1175103 Dec 10 17:35:53 IMAP(user@domain 192.168.2.92): Info: Disconnected: Logged out bytes=15964/44364 Dec 10 17:35:53 IMAP(user@domain 192.168.2.92): Info: Disconnected: Logged out bytes=54758/944989 Dec 10 17:35:53 IMAP(user@domain 192.168.2.92): Info: Disconnected: Logged out bytes=6532/43930 Dec 10 17:35:53 IMAP(domain@domain 192.168.2.92): Info: Connection closed bytes=235408/4797272694 As you can see - 4.8Gb of data was send to this client - and who knows - what was that. So we have 5.2Gb send to host with 20 active sessions and 4.8Gb send to one user. Of course lifetime of this connection can be much more than last day, but problem disappeared after killing it. This is not single accident. But this one was hard to find out because of 20-25 users working at the same time from 1 server. So it will be great if dovecot has feature to limit the amount of data send per connection. For example: service imap { bytes_per_connection = 100Mb } And after limit reached - close connection and log warning. This will much simplify fights with sometimes become crazy imap clients. That do you think?

by Giovanni Mancuso 13 Dec '10

13 Dec '10

Hi, can i configure dovecot to limit the max number of login concurencly? I read in documentation that there is "mail_max_userip_connections", but in this way i limit the login that come from same ip. If the same user tries to connect from different ip, he succeeds. Can i do it? Thanks
