Procmail wiki text -- don't muck with SENDMAIL
by era eriksson 16 Jun '14

16 Jun '14

I tried to edit http://wiki2.dovecot.org/procmail but got stuck on the TextCha. Approaching this list instead seems to be a time-tested secondary approach, and I wasn't completely comfortable making these changes without discussion anyway. So here goes. The SENDMAIL= assignment is not only irrelevant, but actually wrong. The note down in the update section about Ubuntu explains the problem well enough, but it applies to all the sections on the page. My proposed edit was to simply remove SENDMAIL and SENDMAILFLAGS from all the recipes on the page, and then remove the Ubuntu section altogether, because it would no longer add anything useful to the page. If somebody in the Dovecot community with edit access to the wiki wants to implement this change, I would be grateful on behalf of the people who try to use Procmail with Dovecot. -- If this were my real .signature, it would suck less. Well, maybe not.

connection to director (lmtp) time out
by Patrick Westenberg 16 Jun '14

16 Jun '14

Hi all, I'm running two directors with lmtp proxy as relay transport for my mail exchangers. relay_transport = lmtp:inet:dovecot-directors.example.net dovecot-directors.example.net resolves to 172.17.1.3 and 172.17.1.4 Now, .3 is down and Postfix tries to deliver it to .4 but this connection gets a timeout: (delivery temporarily suspended: connect to 172.17.1.4[172.17.1.4]:24: Connection timed out There is no log entry on the director. Can anyone give me a hint how to solve this or maybe optimize my configuration?

[Dovecot] Pigeonhole and dsync replication not replicating 'SETACTIVE' for a sieve script
by Skeffling 16 Jun '14

16 Jun '14

Hello, I'm testing dovecot replication alongside pigeonhole and liking it. Dovecot v2.2.13 Pigeonhole v0.4.3 If I create or edit a sieve script on one server (via managesieve, using the thunderbird plugin as it happens) then it does get replicated to the other - great! However, if I set a script to be active (SETACTIVE) on one side then this is not being replicated across to the other server. Is this a known issue? Thank you! -- Andrew

[Dovecot] Outlook 2007 & 2010 hangs in v2.2?
by Timo Sirainen 15 Jun '14

15 Jun '14

Has anybody noticed Outlook 2007 & 2010 (but apparently not 2013) hanging IMAP connections with Dovecot v2.2 (but not v2.1) when they're FETCHing large mails? I can't think of any reasonable explanation for this.

[Dovecot] doveadm index - Bug or expected behaviour?
by Bruno Galindro da Costa 13 Jun '14

13 Jun '14

My ldap config is using the variable %d in base search for domain replacement when dovecot will search for users in LDAP. Its works fine for dovecot operation. But, for doveadm index, not. It ignores that variable and tries to pass a base search without domain. So, the search will not working. This is the command: # doveadm -v index -A INBOX This is my config: # cat /etc/dovecot/dovecot-ldap-userdb.conf hosts = 10.0.0.1 tls = no auth_bind = no ldap_version = 3 base = ou=%d,ou=mail,ou=services,dc=domain scope = subtree deref = never user_filter = (& (cn=%n)(objectclass=nisMailAlias)(ContaAtiva=TRUE) ) user_attrs = cn=rfc822mailmember,EmailQuota=quota_rule=*:storage=%$M,EmailQuotaSpecial=quota_rule=*:storage=%$M,eduPersonPrincipalName=eppn iterate_filter = (&(objectclass=nisMailAlias)(ContaAtiva=TRUE)(!(EmailQuota=0))) iterate_attrs = rfc822mailmember=user This is the error reported by doveadm index: doveadm(root): Error: User listing returned failure doveadm: Error: Failed to iterate through some users If you put a tcpdump to monitor the search, you i'll see 3 packets.

Subject tag [Dovecot] is gone
by Timo Sirainen 13 Jun '14

13 Jun '14

I've actually been thinking about it almost since the beginning. It's just been annoying waste of space on my screen. And more importantly nowadays it's also breaking DKIM/DMARC signatures. So if somebody still uses Subject-based filtering it's about time to switch to List-ID header based filtering now. Another thing I'm wondering about is if I should allow text/html parts, because removing them will also break the DKIM signatures. Or mainly I'd like to allow only multipart/alternative with text/plain + text/html, but I don't think I can configure Mailman to support that.

display SSL version?
by Zube 12 Jun '14

12 Jun '14

Sorry for the bother, but is there any way to poke or prod or query dovecot so that it will reveal what version of SSL it is currently using? dovecot --build-options tells me that openssl is there, but not the version. ldd on any of the binaries in libexec comes up empty. I can get the version and what directory it is looking at by: strings ssl-params | grep -i ssl but that is kludgy. CentOS 5, dovecot 2.2.13. Thanks for any help. Cheers, Zube

A solution : dsync(someuser) Error: Mailbox GUIDs are not permanent without index files
by James Rogers 12 Jun '14

12 Jun '14

While migrating from mbox to maildir using dsync, I kept running into a brick wall. Some folders would not sync. The message in stderr was: Error message GUID: Mailbox GUIDs are not permanent without index files. This is what solved things for me. I hope this might help someone. Let me know if I'm completely off sides. When working with dsync to migrate from mbox to maildir format mailboxes, I kept running into the error: dsync(someuser): Error: Couldn't get mailbox Drafts GUID: Mailbox GUIDs are not permanent without index files dsync(someuser): Error: Couldn't get mailbox Junk E-mail1 GUID: Mailbox GUIDs are not permanent without index files dsync(soemuser): Error: Couldn't get mailbox TO DO LATER - US GUID: Mailbox GUIDs are not permanent without index files dsync(someuser): Error: Couldn't get mailbox Notes GUID: Mailbox GUIDs are not permanent without index files dsync(someuser): Error: Couldn't get mailbox Orders Pending GUID: Mailbox GUIDs are not permanent without index files dsync(someuser): Error: Couldn't get mailbox Junk E-mail GUID: Mailbox GUIDs are not permanent without index files dsync(someuser): Error: Couldn't get mailbox Server Mgmt+Config GUID: Mailbox GUIDs are not permanent without index files The error messages were helpful, but it would be nice to know what prevented the creation of the indexes in the errors (permissions, settings, disk space, etc.). I finally figured it out semi-randomly when I dumped my doveconf file using doveconf -n, and saw: mbox_min_index_size = 100 k I felt very um... happy? And not too bright. The following made my problems go away, and the sync worked flawlessly. mbox_min_index_size = 0 I guess it's best to set this using dsync -o'mbox_min_index_size=0' Mail now converts quickly and completely even for 0 length mailboxes (i.e. empty folders are created). Also, I would like to note that mb2md.pl should not be used to convert mbox to maildir. The regex used to split mboxes will fragment messages. mb2md.pl uses: if ( /^From / And in the very least, the following would be less harmful: if ( /^From\s+(\S+.*(a)\S+.*|MAILER.DAEMON)\s+.*$/ I love dovecot. I knew it must be something bone-headed I just wasn't seeing. And now I can go get some rest. --James W. Rogers

lazy_expunge mangles dovecot-acl-list
by Christoph Bußenius 12 Jun '14

12 Jun '14

Hi, I think I found a bug in Dovecot 2.1.17 and 2.2.13. In our setup, sometimes ACLs stop working because "dovecot-acl-list" is replaced by an empty file. We found that lazy_expunge is connected to this. To reproduce, create ACLs for "user1" in a folder. Put a mail in that folder and expunge it, so that the folder will be created in the "expunged" namespace. For instance, # cat user1/mail/mailboxes/folder/dbox-Mails/dovecot-acl user=user2 keilrwts # cat user1/mail/dovecot-acl-list 1350914868 folder # doveadm -f flow fetch -u "user1" 'guid' mailbox _EXPUNGED.\* # ls -l user1/mail/dovecot-acl-list -rw------- 1 vmail vmail 0 2014-06-12 11:40 user1/mail/dovecot-acl-list You see that we have used doveadm to list the expunged namespace, which has emptied the "dovecot-acl-list" file.

Parse dovecot 2.2 logs with logstash

12 Jun '14

Guys, I need to parse my dovecot log files with logstash grok patterns. Is there any document specifying the patterns used by dovecot to write it's logs? I need to find all the log possibilities that could be writed to log files by dovecot. So, if a document like that exists or if anyone could answer my question, I'll could make the parser with less difficult. -- Att. Bruno Galindro da Costa

Converting mailboxes from one Maildir format to another
by Patrick C 12 Jun '14

12 Jun '14

I am currently running dovecot 2.0.9 on a CentOS 6 server with the following layout for mailboxes: mail_location = maildir:~/Maildir I would like to change the layout to this format to match the output of other software packages such as offlineimap, mbsync, etc: mail_location = maildir:~/Maildir:LAYOUT=fs:INBOX=~/Maildir/INBOX Is there a way to convert the mailbox layout for all mail accounts currently on the server? I was looking at dsync, but there aren't any Maildir <--> Maildir examples. I was also looking at potentially writing a script to manually rename directories/move files around to match the new format, but wasn't sure whether that would mess with UIDs or other dovecot internals. pat patrickc81(a)gmail.com

Safe to downgrade 2.2 to 2.1?

11 Jun '14

Hi, is it safe to downgrade Dovecot 2.2 to 2.1 (in my case 2.2.13 to 2.1.17 with mdbox format) or will there be troubles with index files and backup/restore is recommended? Unfortunately with 2.2+ it is not to be possible to use acl + lazy_expunge together anymore, so downgrading is the only option for me... @Timo, please fix acl + lazy_expunge in 2.2 if you find some time.

Change index location problem

11 Jun '14

Hi All, I was unable to change location of Dovecot indexes. Currently they are under /var/vmail/%d/%u, but I want to change them to /media/ephemeral0/%u I've changed conf line in /etc/dovecot/dovecot.conf: mail_location = maildir:/var/vmail/%d/%u:INDEX=/media/ephemeral0/%u and setup permissions of /media/ephemeral0 to dovecot:dovecot, tried also vmail:mail (which is default user for e-mails) and also tried with 777 on all dirs, but Dovecot is keeping creating indexes on the old location. I tried moving them from old to new location, but Dovecot recreates them on the old location. Details: # dovecot --version 2.0.9 # doveconf -a | grep location mail_location = maildir:/var/vmail/%d/%u:INDEX=/media/ephemeral0/%u Has anyone experienced something similar, any solution for this? Thanks in advance! -- View this message in context: http://dovecot.2317879.n4.nabble.com/Change-index-location-problem-tp48468.… Sent from the Dovecot mailing list archive at Nabble.com.

I have a filter that colorizes messages that have no SPF or a missing DKIM or bad DKIM signature. I *have* noticed that a lot of messages from the list get marked in such manner, but it never really bothered me and I never thought about it much. Now I understand why that happens (the [Dovecot] identifier in the subject). When trying to solve a problem, the first thing is to correctly identify the problem. You cannot solve a problem if you do not even know what it is. The underlying problem is to identify and classify emails as ones you want and ones you do not want. This is not easy and involves reading a person's mind. A person may, depending on their mood, classify the same email differently at different times, which complicates things. DKIM assumes that you can, in many cases, classify emails this way based on authenticating the *domain* of the sender. This has some serious flaws in that it does not address this issue, even though it purports to. One way to classify an email as "wanted" is if it comes from someone you know and want to communicate with. Signing based on a domain does nothing to address this. If my girlfriend is judy(a)yahoo.com, I want to receive her emails. That does not means I want to receive all emails from the yahoo.com domain. I do not want someone else to impersonate her. If later, we break up and I no longer want to receive her emails, DKIM does nothing to help with that, either. That could be OK if such functionality is beyond its scope. DKIM erroneously bundles sender authentication with message validation. I want to know that it really was judy(a)yahoo.com that sent me the message and not someone trying to impersonate her. However, as a separate function, I would like to know that the message I received is not the one she sent. These functions should not be integrated. As it is now, if the signature does not verify, I do not know why. Was the sender spoofed? Was some part of the message modified in some way? And just for the record, I believe that the subject line should conceptually be treated as part of the message, along with the date. DKIM is too strict. If I want to present a legal document (email) in court, I may want to prove that the document I present to the court is exactly as it was when it was sent to me. However, this is not a common occurrence. The real world is messy and imperfect and often, changes to emails are innocuous and legitimate. Mailing lists are an example of this. A mailing list or anti-virus scanner *should* be able to add a footer or add a mailing list identifier to the subject line, as long as those changes can be marked as later additions that the original sender is not accountable for. An email program should make it clear to the recipient which parts are not accountable to the original sender. I am not proposing a new standard, simply pointing out that breaking an established protocol (by removing the [Dovecot] subject identifier) because of a flawed anti-spam system is not in people's best interest. Can a spammer spoof messages from the list? Sure. Has it happened? Not that I am aware of. Is it a problem? Not so far. So why, then, make people go through all this trouble of setting up new filters and rules, mail routing, software upgrades, etc, just to appease a standard that is clearly broken? Dem

replication with plugin won´t work
by Florian Schaal 11 Jun '14

11 Jun '14

Hi all, i try to setup a master-master replication with dovecot / dsync. I´m using virtual-users. When I call doveadm sync -A remote:vmail@server2 new mails are copied to the second server, but new messages from server 2 not on Server 1. To fix this i run doveadm sync -A remote:vmail@server on the 2nd server But I want that it works with dovecot / dsync (see my config at the end - identical on bot servers, only mail_replica is different). I added some services regarding http://wiki2.dovecot.org/Replication If i send a local mail on one server it will not be replicated to the other server until i run doveadm sync. Maybe i just missed some steps in my setup? doveadm user '*' displays the right users on both servers. === docecot.conf === # 2.2.13 (7b25994a8cb7): /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-042stab076.8 x86_64 Debian 7.5 auth_mechanisms = plain login ntlm disable_plaintext_auth = no dsync_remote_cmd = ssh -p 4711 -l%{login} %{host} doveadm dsync -u%u listen = *,[::] log_timestamp = "%Y-%m-%d %H:%M:%S " mail_debug = yes mail_plugins = " notify replication" mail_privileged_group = vmail passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { mail_replica = remote:vmail@server2 quota = dict:user::file:/var/vmail/%d/%n/.quotausage replication_full_sync_interval = 1 hours sieve = /var/vmail/%d/%n/.sieve } protocols = imap pop3 service aggregator { fifo_listener replication-notify-fifo { mode = 0666 user = vmail } unix_listener replication-notify { mode = 0666 user = vmail } } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail mode = 0600 user = vmail } user = root } service config { unix_listener config { user = vmail } } service doveadm { user = vmail } service imap-login { client_limit = 1000 process_limit = 500 } service replicator { process_min_avail = 1 } ssl_cert = </etc/postfix/smtpd.cert ssl_key = </etc/postfix/smtpd.key userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota pop3_uidl_format = %08Xu%08Xv } protocol lda { mail_plugins = sieve quota } === docecot.conf === regards Florian

[Dovecot] Can't get authentication for masterusers on Mac OS X Server 10.6.8
by Gilles Celli 11 Jun '14

11 Jun '14

Hi dovecot masters, This is my first post here, since I desperately need some advices from the dovecot community. I've tried to get an answer on the Apple Forums but til now no luck....here we go: I've tried to sync our users emails (Mac OS X Server 10.6.8 Snow Leopard with dovecot 1.1.20-apple0.5) via imapsync to our new server by using the masterusers authentication method on the old 10.6.8 server... The main problem on OS X Server 10.6.8 is that dovecot 1.1.20 uses the OD (OpenDirectory) driver (well I think), so that when following the directions of Master users/password from this page I can't login with the http://wiki1.dovecot.org/Authentication/MasterUsers I couldn't find anything on the OD driver directive....the dovecot 1.1.20-apple build doesn't even have the shadow driver built in (see below the dovecot --build-options), so that passdb shadow {} won't work anyway I always get NO Authentication failed, when trying the following: >telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK Dovecot ready. 1 login user1*mailadmin PASSWORD 1 NO Authentication failed. I've tried also to add a Post-login scripting like described here, but no luck either: http://www.stefanux.de/wiki/doku.php/server/dovecot Does someone know how to fix my migration issue ? Any help is greatly appreciated.

Dovecot auth NTLM
by dovecot.lista＠palacio.cu 10 Jun '14

10 Jun '14

Hello, this is my first email to the list... i´m configuring Dovecot with NTLM authentication, at least this is what i wanted, but i´m having a few problems. 1-I made my configuration following the steps from this howto http://wiki2.dovecot.org/HowTo/ActiveDirectoryNtlm from the dovecot official site, but my dovecot´s version is 2.1.7 and the tutorial dovecot´s version is 1.1.16. But, the fact is that when i enter to the wiki1, for the version 1.x i found that all the howtos are obsoletes and the tutorial for the version 1.x is the same for the 2.x version, so this howto is not trustful.... but, there is not another one. 2-When i implement it all seems to work OK, but the communication between dovecot and the helper in "/usr/bin/ntlm_auth". I made the tests with the binary(/usr/bin/ntlm_auth) and i got the right answers from it, and i also made the test with the tool wbinfo and were successful. During the tests i was monitoring the logs of my Domain Controller (The server from where i want to authenticate) and it logged all the requests i made however when i try to authenticate with dovecot in my Domain Controller nothing is written in the logs... then i get to the conclusion that Dovecot is not communicating with the helper, and of course in dovecot´s logs appears: auth: Info: winbind(?,10.10.10.10): user not authenticated: NT_STATUS_UNSUCCESSFUL As i said, my friends, there is no any other tutorial or howto in internet, at least i did not see it. I´m asking for your help... if any of you have configured Dovecot to auth against NTLM, please tell me how. Im working on Debian Wheezy and Dovecot 2.1.7. PS:Please forgive my English i speak Spanish

Bug when virtual mailbox is set to auto=subscribe

[Dovecot] Issues with VANISHED CHANGEDSINCE
by Michael J Rubinsky 09 Jun '14

09 Jun '14

I've been seeing the following wonky behavior with Dovecot. Currently this is with Dovecot 2.0.19, but I was also seeing it in earlier versions as well, including versions from the 1.x series. Some background, this is from Horde's ActiveSync library, when it is trying to determine what UIDs have recently been expunged. I can guarantee that when this command was sent, there was only one or two emails that were removed since the provided MODSEQ value. C: 8 UID FETCH 1:* UID (VANISHED CHANGEDSINCE 587742) S: * VANISHED (EARLIER) 1:119944,119947:123482,123484:128043,128045:130388,130390:130456,130458:132127,132129:135832,135834:136201,136203:136301,136303:136316,136318:138502,138504:140099,140101:141908,141910:142607,142609:142744,142746:142865,142867:143160,143164:143173,143176:143179,143181:143187,143189:143190,143192:143195,143197:143270,143272:143273,143275:143280,143282:143302,143305:143307,143309:143318,143320:143333,143335:143337,143339:143341,143343:143375,143377:143400,143402:143551,143553:143637,143640:143706,143708:144069,144071:144178,144180:144307,144309:144316,144318:144329,144331:144931,144933:144983,144985:145000,145002:145069,145071:145072,145074:145132,145136:145178,145180:145191,145193 Also, to verify it wasn't something screwy with my server, Michael Slusarz provided me with this from his server: <quote> There's definitely something wonky going on in the code.

[Dovecot] checkpassword memory limit

Hi. I am trying to authenticate dovecot from a wordpress database. I was thinking of using the checkpassword script to start a cli php script. That php script would then include the necessary wordpress functions, do the auth (find the wp username from user database using the email address, and authenticate with the user/pass), and return the result to the checkpassword script. I made the above scripts (the php script will be used to authenticate some other services too), and when I run them "by hand" (even with "sudo -u dovecot ..."), it works. But, when the dovecot runs them, the php runs out of memory. After a lot of debuging, I find out that when the dovecot starts the checkpassword script, it makes a 250kB memory limit. But it is not enough for the php script, it needs 14MB. I tried to put a "ulimit -v 16777216" into the checkpassword.sh, but it doesn't work.Is there some hardcoded limit in the dovecot itself? And if there is, could it be somehow changed?I am using a simple D ebian Wheezy LAMP, and installed everything from repo. Thanks for every idea.

[Dovecot] Authentication Failure (newbie)
by Danny Gorton 08 Jun '14

08 Jun '14

Greetings, I'm am learning about running a mail server and I set up a brand new Ubuntu 14.04 server with postfix and dovecot. I had some initial problems with dovecot not starting, and then with not having proper permissions/access to the various directories and files and pipes, etc, and in the process starting to learn how this thing works. After searching in web-land I seem to have overcome those issues and dovecot and postfix both start and accept connections now (http://wiki2.dovecot.org/TestPop3Installation) However when I check to see if I can authenticate I get Authentication Failed. At the time of these login attempts there are no messages added to syslog or mail.log, dovecot log entries are below. Note I redacted my test user and password values to 'xxxxx', and my domain value to 'domain.com'. Also I'm testing with my plain text password, but I've tried using AUTH PLAIN <base64 encoded uid/pwd>. I have also tried the setup with a default auth domain, and I've tried authenticating with and without the domain name as part of the user name, with the same results. I added the debug settings and disable_plaintext_auth = no to try to solve this issue. Here is my test command set: xxxxx@apacweb:~$ sudo doveadm user xxxxx field valueuserdb lookup: user xxxxx doesn't exist and : xxxxx@apacweb:~$ telnet localhost 110 Trying ::1... Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. +OK Dovecot (Ubuntu) ready. user xxxxx +OK pass xxxxx -ERR [AUTH] Authentication failed. Here is a cut from the dovecot log: 2014-06-08 01:22:10 auth: Error: passwd-file(xxxxx): stat(uid=vmail gid=vmail home=/home/vmail//xxxxx /etc/dovecot/users) failed: Address family not supported by protocol I figure this is the root cause of this issue and the solution to it is supposedly to tell dovecot to not listen on IPv6 (listen = *), but I did that and it didn't help (see config). Here is a cut from the dovecot.info log: 2014-06-08 00:16:25 auth: Debug: auth client connected (pid=3131) 2014-06-08 01:22:10 auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth 2014-06-08 01:22:10 auth: Debug: Read auth token secret from /var/run/dovecot//auth-token-secret.dat 2014-06-08 01:22:10 auth: Debug: passwd-file /etc/dovecot/passwd: Read 1 users in 0 secs 2014-06-08 01:22:10 auth: Debug: master in: USER 1 xxxxx service=doveadm 2014-06-08 01:22:10 auth: Debug: userdb out: NOTFOUND 1 Here is my dovecot config: # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux 3.13.0-24-generic x86_64 Ubuntu 14.04 LTS ext4 auth_debug = yes auth_debug_passwords = yes auth_mechanisms = plain cram-md5 auth_verbose = yes base_dir = /var/run/dovecot/ disable_plaintext_auth = no info_log_path = /var/log/dovecot.info listen = * log_path = /var/log/dovecot log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = maildir:/home/vmail/%d/%n/Maildir passdb { args = /etc/dovecot/passwd driver = passwd-file } protocols = imap pop3 service auth { executable = /usr/lib/dovecot/auth unix_listener /var/spool/postfix/private/auth-client { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { group = postfix mode = 0777 user = postfix } user = vmail } service imap-login { chroot = login executable = /usr/lib/dovecot/imap-login user = dovecot } service imap { executable = /usr/lib/dovecot/imap } service pop3-login { chroot = login executable = /usr/lib/dovecot/pop3-login inet_listener pop3 { address = * port = 110 } inet_listener pop3s { address = * port = 995 } user = dovecot } service pop3 { executable = /usr/lib/dovecot/pop3 } ssl = required ssl_cert = </etc/ssl/certs/smtpd.crt ssl_key = </etc/ssl/private/smtpd.key userdb { args = uid=vmail gid=vmail home=/home/vmail/%d/%n /etc/dovecot/users driver = passwd-file } valid_chroot_dirs = /var/spool/vmail protocol pop3 { pop3_uidl_format = %08Xu%08Xv } I'm sure I've done something stupid, but after thrashing about for some days I haven't been able to figure out what it is.

[Dovecot] Running dovecot under Cygwin
by Manolis Spanakis 06 Jun '14

06 Jun '14

Hi, In http://wiki2.dovecot.org/DovecotFeatures I found the following statement regarding devcot support of cygwin: Cygwin works after a few code changes, but doesn't support SCM_RIGHTS I downloaded "dovecot-2.2.13.tar.gr" and tried to compile it under cygwin version 1.7.30 (0.272/5/3) CYGWIN_NT-6.3-WOW642.580 (32-bit). As I executed the: $./configure I got the following error: error: fd passing is required for Dovecot to work If I bypass this error by changing "configure" I get no other errors either in "configure" or "make". It seems that "src/lib/fdpass.c" is the only library incompatible with cygwin. Is there any file version available that provides a solution? Thank you in advance, Manolis Spanakis

[Dovecot] CRAM-MD5 authentication memory leak problem.
by Kenji Tonami 06 Jun '14

06 Jun '14

I used dovecot Auth daemon for postfix SMTP Auth. I saved clear password to OpenLDAP, then I set up that as the password will be used. There ware no trouble when authentication had sucessed. But when authentication failed by using "CRAM-MD5", it caused increasing memory allocation of dovecot auth daemon. In case of using "PLAIN" or "LOGIN", there were no problem even if authentication had failed. I got same result on dovecot-2.0.9(RHEL6) and dovecot-2.2.13. Does anyone know similar case? I tried restarting dovecot Auth daemon by using service_count parameter in service auth settings. When authentication failed, message on postfix was as follows: ** 535 5.7.8 Error: authentication failed: "CRAM-MD5 string" When authentication failed and restarting dovecot auth daemon at the same time, message on postfix was changed as follows: ** 535 5.7.8 Error: authentication failed: Connection lost to authentication server It looks like that the failed authentication request is suspended by restarting auth daemon. -- config (10-auth.conf) auth_mechanisms = plain login cram-md5 -- -- config (10-master.conf) service auth { executable = auth unix_listener /var/spool/postfix/private/auth { mode = 0666 user = postfix group = postfix } } -- -- auth-ldap.conf.ext passdb { driver = ldap args = /etc/dovecot/ldap-passdb.conf.ext } -- -- ldap-passdb.conf.ext host = xxx.xxx.xxx.xxx dn = LDAP Manager DN dnpass = Manager DN password base = ou=mail,dc=xxxxxx,dc=xx scope = subtree pass_attrs = mailID=user,mailClearPassword=password pass_filter = (mailID=%u) auth_bind = no default_pass_scheme = plain -- Thanks. -- Kenji Tonami

It turned out to be a TCP scaling problem. If a router/firewall drops packets with a TCP scaling option set, the endpoints disagree on how many outstanding non-ACK packets are allowed, resulting in timeouts. http://support.microsoft.com/kb/935400 http://en.wikipedia.org/wiki/TCP_window_scale_option The Microsoft KB does hint those versions of Outlook may be affected, but I can't figure out why there would be a difference between Dovecot 2.1 and 2.2.

[Dovecot] Sharing folder with others
by Claudinei Santos 05 Jun '14

05 Jun '14

Hello, The sharing folders with dovecot works, but when the user that i shared the folder reads any e-mails in the folder, all my subcribed folder (the folders that i do not shared with this user) is unsubcribed from my account. The only folders that remains is the default ones ( inbox, trash, spam and sent) and the folder that i shared with that user. my configurations: # separator for master-users, example: "login_user*master_user -> user(a)domain.tld*masteruser auth_master_user_separator = * passdb passwd-file { driver = passwd-file args = /etc/dovecot-masterusers master = yes } namespace private { type = private separator = / prefix = #location defaults to mail_location. inbox = yes } namespace shared { type = shared separator = / prefix = Share Folders/%%u/ location = maildir:/var/spool/mail/vmail/%d/%%n:INDEX=/var/spool/mail/vmail/%d/%n/shared/%%u subscriptions = yes list = children } # cat /etc/dovecot-postlogin #!/bin/bash export MASTER_USER="$USER" exec /usr/lib64/dovecot/imap "$@" Can someone help me out with this?

[Dovecot] What are the options for HA and\or replication and\or storage?
by Eliezer Croitoru 05 Jun '14

05 Jun '14

I am considering couple options of converting a current service into a HA using multi servers or any other solutions. The point is that I am thinking about the options and which I am looking for. NFS can be a storage which has it's own pros and cons. There is the option of DRBD but as of now it's limited for two hosts. What options do exist out-there as a solution? The main issues are that the current service is based on Maildir and is on one server with resierfs. The service is composed of one host with 50k users couple disks in raid6. On the same machine we have postfix as mailer. I would like to hear about HA environment that I can use to replicate the boxes. My basic research leaded me to smtp on one host or more and using lmtp to send the messages to dovecot o another host which will have a replicated host and will be used with storage system based on ISCSI or NFS. Any other idea to enhance the current one or to replace it is more then just welcome. Thanks, Eliezer

[Dovecot] General questions about TCP replication with dsync
by Patrick De Zordo 05 Jun '14

05 Jun '14

Hi Guys, I would like to question why I see this errors in my logs. Let explain me! Dovecot version: 2.2.9 (on Ubuntu 14.04 LTS) Ive configured our dovecot servers (2 servers) to do the TCP replication with dsync. This is working flawless. 1. Question: In logs I can see this errors on every sync (on the slave server / server without changes which should be updated): ---8<----------------------------------------------------------------------- ---------------------------------------------------------------------------- ---- dsync-server(email(a)example.com): Error: net_connect_unix(/var/run/dovecot/replicator-doveadm) failed: Permission denied ---8<----------------------------------------------------------------------- ---------------------------------------------------------------------------- ---- Googling a bit gave me the information This should be normal..? Well ok, errors in logs are not nice to see, but can someone confirm this is really ok? Timo? 2. Question (much more important): We are using sieve scripts for our users, they are replicated to the replica-host but this errors appears in logs on every synchronized message: ---8<----------------------------------------------------------------------- ---------------------------------------------------------------------------- ---- dsync-server(email(a)example.com): Error: Failed to access mailbox dovecot/sieve: Internal error occurred. Refer to server log for more information. dsync-server(email(a)example.com): Error: stat(/var/vmail/example.com/email/.dovecot.sieve/tmp) failed: Not a directory ---8<----------------------------------------------------------------------- ---------------------------------------------------------------------------- ---- So whats going on there? This is strange and should not be, right? Any hints? Thank you very much! --------------------------------------------------------------------- Mit freundlichen Grüßen / Distinti saluti / Kind regards De Zordo Patrick patrick(a)spamreducer.eu

[Dovecot] IMAP copy fails because the mailbox size of user1 is exceeding the quota limit of user2??
by Katja Wegner 05 Jun '14

05 Jun '14

Hi all, I do have a mailbox-quota problem in dovecot 2.0.19 that is beond my understanding. Could someone pls. give me a hint. - user1 max. mailbox quota is set to 1GB, the current mailbox size of user1 is 15MB - user2 max. mailbox quota is set to 10MB, the current mailbox size of user1 is 10kB - user1 shares the folder 'shared_folder' to user2 with all rights (read, write ...) - user2 has subscribed to 'shared_folder' the problem: - user2 tries to move a mail (20kB) to the shared folder via telnet: ". copy 1:1 shared/user1/shared_folder" - it fails with: "NO [OVERQUOTA] Quota exceeded (mailbox for user is full)" - copying the same mail to a local folder of user2 works without problems. - After I raised the max. mailbox quota of user2 from 10MB to 16MB it was possible to move the mail to the 'shared_folder' of user1. It looks like the copy operation fails because the mailbox size of user1 is exceeding the quota limit of user2! Is this possible? Is this a bug?

[Dovecot] attachment sis + EMLINK (too many links) = segfault bug (2.2.12)
by Pavel Stano 05 Jun '14

05 Jun '14

Hi, we use attachment dedup with lots of emails (still migrating to it from maildir). We use netapp storage with wafl filesystem over nfs. Problem is that netapp has hard limit of 100k hardlinks to one file. And we encountered it. Problem is that dovecot start do segfault (lmtp,dsync,pop3 etc) when it happend when tried to deliver new emails with that attachment. Here is strace of dsync: 6740 link("/nfsmnt/mailatch1/f9/10/hashes/f9108ddaa156ac15738e41ed3bedec1eda50175d", "/nfsmnt/mailatch1/f9/10/f9108ddaa156ac15738e41ed3bedec1eda50175d-7bb7a20ddb598853541a000028db4a9f") = -1 EMLINK (Too many links) 6740 --- SIGSEGV (Segmentation fault) @ 0 (0) --- ls -lh: -rw------- 100000 vmail vmail 4.7K Apr 28 16:54 /nfsmnt/mailatch1/f9/10/hashes/f9108ddaa156ac15738e41ed3bedec1eda50175d We were using mail_attachment_min_size=4kb, we solve it by increasing it to 8kb. It would be nice to somehow fix this problem. Like not crash when EMLINK happend and maybe do not deduplicate attachments but deliver email without dedup. Or create second file in hashes/ and start hardlinking it instead of original. AFAIK ext4 has also hard-link limit 64k (http://en.wikipedia.org/wiki/Hard_link#Limitations_of_hard_links) So this can happen to anyone with lots of emails.

[Dovecot] Plugin mail-filter tangles
by Stanislas SABATIER 05 Jun '14

05 Jun '14

System installed : Dovecot 2.2.12 as IMAP server and Postfix as MTA. Dovecot and Postfix connected via LMTP + Dovecot mail plugin 'mail-filter' to encrypt/decrypt emails on the fly with public/private users' RSA keys. Case study : You have 3 (virtuals) users belonging to 3 different domains, all managed by your Dovecot server. One of these users is connected to Dovecot with MUA Thunderbird, and he's writing an email to someone outside of yours domains, but he puts the two others users' email addresses in CC : mail from user1(a)domain1.dovecot --> to: someone@outside, CC: user2(a)domain2.dovecot, user3(a)domaine3.dovecot What happens (as far as I can understand) : The email is submitted to Postfix : one copy is delivered outside, the other is passed to Dovecot via LMTP for user2 & user3 @dovecot Dovecot is handling the final delivery, through mail-filter plugin as follow : 1. both users contexts are created from user_db queries 2. mail-filter plugin is init for user2 3. /mail_user_created/ for user2 4. mai-filter plugin arguments are parsed for user2 5. â¦/mail_allocated/ then /mail_save_begin/ for user2 (at this stage, the email is encrypted with users2 params) 6. Dovecot tells to LMTP that mail for user2 is delivered 7. then, â we are still in user2 context â, an other /mail_allocated/ is run, followed by a /istream_opened/ 8. mail user context is swithed to user3 --> /mail_user_created/ --> plugin's args parsed --> â¦ /mail_allocated/ 9. andâ¦ Dovecot tells to LMTP that mail for user3 is delivered So, it appears that Dovecot is re-using user2's email to pass it to user3 by opening an istream in user2's context. In my configuration, Dovecot can't do that because it has not the user2's private rsa key to reopen the email it has just encrypted, so it passes the email to user3 with user2 encryption params. Final result : user3 is receiving the email encrypted with user2's rsa key ! Problem : how to force Dovecot to deinit then reinit mail-filter plugin for each user to be sure that each email is encrypted with the right key before it is saved to users' mailboxes ? Thank you in advance for your help. Stan.

[Dovecot] SQL passdb, LDAP userdb
by Kristof Bajnok 05 Jun '14

05 Jun '14

Hi, in my current setup, LDAP authentication + userdb works fine. I'd like to integrate Dovecot with Shibboleth. I have a custom module at the IdP (*) that inserts short-time tokens to an SQL table at user authentication, and I want Dovecot to use the token table for passdb but keep LDAP for storing the userdb (uid, quota, etc) I thought it was simple as omitting the sql user_query, but I got: Warning: mysql: Query failed, retrying: Table 'webmail.users' doesn't exist Error: sql(user@domain,ipaddr): User query failed: Table 'webmail.users' doesn't exist (using built-in default user_query: SELECT home, uid, gid FROM users WHERE username = '%n' AND domain = '%d') Do you have any hints how to do this? Thanks, Kristof (*): in SAML there is an Identity Provider that does user authentication, which is separated from the services

UID 26624 is a valid user ('info' of domain14552) but under a compleltly different domain name (hamish is under domain25367). However that user has also not logged in around the time the ownership was changed. There is no relevance to the two users, except that they exist on the system and for some reason this issue happened to the hamish user. The NFS server does not know about the UIDs, it just provides the numeric IDs which is translated on the dovecot/exim servers by NSS and Dovecotr using the replicated MySQL database. Additionally both users have existed for some time and the databases are in sync. Customers also do not have any access to the file system so there will be no symlinks in place. Its also not a single server that we are seeing the issue on, it maybe one Dovecot server accessing one NFS server. Then the next time its a different Dovecot server accessing a different NFS server. >> >the logs for that time which is abnormal (a whole bunch of other logins from >> >other customers but nothing from those two users and no errors) > What about cron jobs, message delivery, backups, ... anything that > possibly can alter that file. I don't think, it's a Dovecot issue, unless > the uid 26624 is valid and hamish is shared with that user. Nothing besides Courier being replaced by Dovecot has changed in the server setup (although I could be wrong there, but we are going through one component at a time and until this issue is resolved we are not moving onto the next), and the only file which is being modified is a file which only Dovecot maintains. There are hourly backups which do an rsync to another server in case of hardware failure, there are scripts which move mailboxes between NFS servers but they show up in logs. Exim has no need to touch a dovecot controlled file, and when it writes mail into the maildir its writing as the correct user. It also seem odd that one login is fine then randomly the next login the file ownership has changed, nothing happens in between the two logins which are in some cases only 5 to 10 minutes apart. All I am really looking for is ideas on where to look, as it seems odd that nobody else is reporting this, and since its a reasonably new setup its possibly something we have done in the config (which I posted in my first email). Is there a reliable way to run a script directly when a dovecot session starts and finishes so we could output the ownership before and after which may also help eliminate the session itself. Cheers, Bruce

[Dovecot] empty emails with 2.2.13/pigeonhole
by Cor Bosman 04 Jun '14

04 Jun '14

I recently upgraded from 2.2.10 to 2.2.13, and also upgraded pigeonhole. Ever since im seeing some empty emails appear in my inbox. Return-Path: <cricket(a)stats2.xs4all.net> Delivered-To: <cor> Received: from imapdirector1.xs4all.net ([194.109.26.173]) by userimap9.xs4all.nl (Dovecot) with LMTP id CHu0MUDDjlOBdwAAwvsqNQ for <cor>; Wed, 04 Jun 2014 08:57:04 +0200 Thats all this mail contains. This only happens using LMTP/Sieve, and with many different senders/recipients. Debug log shows nothing out of the ordinary, except that the mail seems to be corrupted by the time it hits sieve. It's very hard to diagnose. Our path is kind of lengthy, and in theory it could happen everywhere. Mail first arrives on incoming MX server which is sendmail. From there it's sent to a dovecot director using lmtp, which sends it to a server that does final delivery with sieve. Im not sure where the email gets corrupted. Any extra debugging I could turn on? Two extra things to note. So far it seems to only happen to emails that would have hit a matching sieve filter rule. I have asked a dozen people to verify this, and all emails would have matched a filter if all was well. Instead, it gets dropped into the inbox because pigeonhole seems to be working with the corrupt file and cant match any rules anymore. And second, 99% of our email is handled differently, from the sendmail server directly into a local mailer, and that never causes issues. We're in the process of switching to lmtp. Any insights? cor

[Dovecot] /etc/passwd userdb and long usernames

hi! i've configured dovecot to lookup usernames in /etc/passwd and it's working ok but it's having some problems retrieving info when the username is longer than 32 chars (i know it isn't recommended but everything seemed to work ok except for the hardcoded limit in useradd...) i found this on logs showing extra characters on the home field: http://pastie.org/pastes/9257902/text?key=vsxstofu3rf5wum4aic5va is there a limit on username length? i "solved" it by setting auth_username_format = %0.30u -- http://partidopirata.com.ar

[Dovecot] Dovecot + NFS + FreeBSD breakage ?
by Xavier Beaudouin 04 Jun '14

Hi, I am trying to update my old mails servers from dovecot 2.1.15 to 2.2.12 (freebsd ports) and upgrade to FreeBSD 10.0-P3. My mail storage are on NFS with index also. On 2.1.15 everything is ok, and in 10-mail.conf I have the good things to be added as wiki tell me (eg http://wiki2.dovecot.org/NFS) BUT, when I try a single connection like : $ telnet ::1 110 Trying ::1...

[Dovecot] Change in LAYOUT=fs between 1.2.9 and 2.0.19?
by Martijn 04 Jun '14

04 Jun '14

While testing an upgrade from Dovecot 1.2.9 (on Ubuntu 10.04 LTS) to 2.0.19 (12.04 LTS) I encountered the following change in behaviour: In both setups, mail_location is defined as follows: mail_location = maildir:~/domains/%d/%n/.Maildir:LAYOUT=fs No other mail_location-related settings are set in the config. On 1.2.9 this leads to new mail being delivered to this example directory: /home/username/domains/example-domain.ext/webmaster/.Maildir/INBOX/new/ On 2.0.19 the exact same mail_location is set, but new mail is now delivered to: /home/username/domains/example-domain.ext/webmaster/.Maildir/new/ Notice the missing /INBOX/ in the path on 2.0.19. I found no mention of this change on http://wiki2.dovecot.org/Upgrading/2.0 which first lead me to suspect this was a bug in 2.0.19. However, while browsing the 2.0-wiki I found a page which sheds some light on the behaviour that is to be expected from Dovecot 2.0.x. Quote from http://wiki2.dovecot.org/MailLocation/Maildir#Directory_layout > "Mailbox directory name": "Without DIRNAME, INBOX will be stored at ~/Maildir/{new,cur,tmp}/, but when DIRNAME is specified, we get an extra path component INBOX/ immediately prior to the DIRNAME value, so in the example above INBOX would be stored at ~/Maildir/INBOX/mAildir/{new,cur,tmp}/." I then changed mail_location to have an empty DIRNAME, like: mail_location = maildir:~/domains/%d/%n/.Maildir:LAYOUT=fs:DIRNAME= It appears this fixes the problem for new mail arriving (haven't tested other folders yet). Questions: 1. Is this a deliberate change in behaviour between the two versions? If so, may I suggest adding this change to the Upgrading to 2.0 wiki page, because I was unable to find the relevant info quickly. If not, is this a misconfiguration on my side, or a (known) bug in one of the two versions? 2. Is the DIRNAME=(empty) a good solution, or is it unusual/hacky to leave DIRNAME empty? Any particular problems I may expect using this configuration? Thanks in advance for your help. -- Kind regards, Martijn

[Dovecot] Info about sharing mail folder
by Gianluca Calloni 03 Jun '14

Hi to all. First of all.. I'm new on the mailing list.. So.. Sorry in advance for any mistake or error on posting here.. The question (or doubt..) is about sharing mail folder. I use a test mail server. Is not the production server (always dovecot + postfix + spamassassin + clamav) Well.. In test mail server i can use the share folder, follow the conf istruction on wiki dovecot. And work fine. But i need to know if is possible for user_a(a)mydomain.com to share only 1 or 2 subfolder (E.g. .INBOX.FOLDER_A and .INBOX.FOLDER_B shared, .INBOX_FOLDER_C not shared) When i do some test sharing folder, the user with wich user_a(a)mydomain.com share the mailbox can view all the subfolder of user_a(a)mydomain.com Following my dovecot versione e config. Thank's in advance My dovecot version is 2.0.19 My dovecot conf is : # 2.0.19: /etc/dovecot/dovecot.conf doveconf: Fatal: open(/etc/dovecot/dovecot.conf) failed: Permission denied calloni@dovecot:~$ sudo -i [sudo] password for calloni: root@dovecot:~# dovecot -n # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.5.0-49-generic i686 Ubuntu 12.04.4 LTS ext4 dict { acl = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } disable_plaintext_auth = no first_valid_uid = 150 last_valid_uid = 150 mail_gid = mail mail_location = maildir:/var/vmail/%d/%u mail_plugins = acl mail_uid = vmail namespace { inbox = yes location = prefix = separator = / type = private } namespace { list = yes location = maildir:%%h:INDEX=~/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { acl = vfile acl_shared_dict = proxy::acl } postmaster_address = postmaster(a)jodovit.local protocols = " imap pop3" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = mail mode = 0600 user = vmail } } service dict { unix_listener dict { group = mail mode = 0600 user = vmail } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } Thi

Not offhand, but if you want a remote tool, it ought to be simple to cobble together some feeder script and netcat (or openssl s_client). It will also be simpler if you configure the master password feature so you don't have access to all user passwords. So something like this for dumping the INBOX contents #!/bin/sh master-user=masteru master-password=masterp while read user server; do netcat --ssl $server 993 <<_EOF_ >${user}.report 1 LOGIN ${user}*${master-user} ${master-password) 2 SELECT INBOX 3 ... 4 LOGOUT _EOF_ done I don't know enough IMAP to fill in "3 ..." to dump all headers, but I'm sure it's not hard to find out. It's even simpler if you don't need to do it remotely: just use doveadm fetch -A hdr MAILBOX '*' Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] list all emails from command line?
by Tomasz Chmielewski 03 Jun '14

03 Jun '14

This is not strictly Dovecot question, but a more general IMAP one. I'm running a Dovecot server and have a user who is claiming that some email sent to him, say, on 30 May, showed up in his mailbox on 02 Jun. I've checked Postfix logs, and the message was correctly received on 30 May and passed to Dovecot. A similar issue happens every few days. This leaves me with two possibilities: 1) Dovecot is somehow not presenting the new mail to the user in a "timely manner" 2) user's email program is broken Therefore, I wanted to do some kind of "IMAP list" of the account, with a command line tool: - specify username, pass and server, - the tool would return a list of all email in their folders (message ID, From, To, Date, Subject). I would run it i.e. daily and this would let me verify when the mail was really visible in the account. Is anyone aware of a tool I could use to achieve that? -- Tomasz Chmielewski http://www.sslrack.com

[Dovecot] dovecot: lda(foo): Error: User foo doesn't have home dir set, disabling duplicate database
by Christian Hoffmann 02 Jun '14

Hello everyone, I have a small problem with dovecot installed on ubuntu-13.10. I use dovcot as LDA with a LDAP-passdb and a pam-passdb. The userdb is static. A mail to LDAP-user 'foo' is delivered with the error-message dovecot: lda(foo): Error: User foo doesn't have home dir set, disabling duplicate database A mail to the pam-user 'bar' will deliverd without this error. But both users should work with the static-userdb. Where is my mistake?

Can someone explain how I can create message rules to use with this version of Dovecot? I specially switched to this version because it supports then Pigeonhole Sieve. I would like to volunteer to contribute as a volunteer when someone would like to create a html driven user interface that provides a user friendly configuration interface and would make such configuration a piece of cake. -- Best regards, Jos Chrispijn --- Artificial intelligence is no match for natural stupidity

[Dovecot] Dovecot 2.1.13: some questions about the mail-filter plugin
by Axel Luttgens 02 Jun '14

02 Jun '14

Looking at mail_filter_mailbox_allocated() of src/plugins/mail-filter/mail-filter-plugin.c: if ((class_flags & MAIL_STORAGE_CLASS_FLAG_OPEN_STREAMS) == 0 && (class_flags & MAIL_STORAGE_CLASS_FLAG_BINARY_DATA) != 0 && muser->out_socket_path != NULL) v->save_begin = mail_filter_mail_save_begin; it seems that a backend with MAIL_STORAGE_CLASS_FLAG_OPEN_STREAMS unset and MAIL_STORAGE_CLASS_FLAG_BINARY_DATA set is expected by the plugin. Technically, this would thus exclude the mbox backend, since its flag configuration seems to be exactly the opposite: struct mail_storage mbox_storage = { .name = MBOX_STORAGE_NAME, .class_flags = MAIL_STORAGE_CLASS_FLAG_MAILBOX_IS_FILE | MAIL_STORAGE_CLASS_FLAG_OPEN_STREAMS | MAIL_STORAGE_CLASS_FLAG_HAVE_MAIL_GUIDS, [...] Is this a correct interpretation? If yes, what is the rationale? I couldn't find any info related to such a limitation in the docs; the README file of http://dovecot.org/patches/2.2/mail-filter.tar.gz even says: "Mail filter plugin can read an email from any storage supported by Dovecot and modify the mail in some way"... All of this stems from my attempts to have working mail filters when I was trying to better understand the behaviors Stanislas was describing in a recent thread... Hence another question; in sdbox-storage.c, the definition of the "alias" for sdbox comes with: struct mail_storage dbox_storage = { .name = "dbox", /* alias */ .class_flags = MAIL_STORAGE_CLASS_FLAG_FILE_PER_MSG, [...] The initialization of member class_flags seems to be incomplete, when compared to the one for the name "sdbox". A typo? On the other hand, Stanislas showed a configuration with mail_location = dbox:/mailboxes/%Ld/%Ln and seemed to have a working mail filter. If above interpretation is correct, this would mean that the "alias" definition isn't used, but that the one for "sdbox" is used instead. Out of curiosity, how/where is that substitution achieved? Regards, Axel

[Dovecot] Combining userdbs
by Bubreg István 01 Jun '14

01 Jun '14

Hi, I think that using more than one userdb with setting the result actions doesn't work as expected from the documentation. The goal would be to set user-specific quotas for a few users with a specific passwd-file like this : cat /etc/dovecot/quotas foo:x::::::userdb_quota_rule=*:storage=2G The first userdb is passwd (with pam passwd): userdb { driver = passwd result_failure = return-fail result_internalfail = return-fail result_success = continue-ok skip = never } The second one is for the specific quota userdb { args = username_format=%n /etc/dovecot/quotas driver = passwd-file result_failure = continue result_internalfail = continue result_success = return-ok skip = notfound } User 'foo' exists in (pam) passd, but there's no place to store his own quota rule, that's why came handy to use a second userdb for storing just one extra field. That's working quiet well, he default quota is overriding form passwd-file. BUT: I've played a lot with changing the result_* and the 'skip' parameters, but none of them worked in the situation where a user ('bar') _only_ exists in passwd (and has to use the default quota config). doveadm quota get -u bar says doveadm(bar): Fatal: User doesn't exist With changing the parameters this error has gone, but the second userdb doesn't used for user 'foo' - even if the parameters are : userdb { driver = passwd result_failure = return-fail result_internalfail = return-fail result_success = continue <-- in theory, the next userdb is coming skip = never } userdb { args = username_format=%n /etc/dovecot/quotas driver = passwd-file result_failure = continue result_internalfail = continue result_success = return-ok skip = notfound } My question is that how should i set the result_* and 'skip' parameters to solve this : - there's a default quota rule in the config - some (a few) users has a larger quota - there's no way to store the user-specific quotas in the 'real' userdb (because it's pam/passwd) Thank you for your effort. # dovecot -n # 2.2.13 (de9b10f2e168): /etc/dovecot/dovecot.conf # OS: Linux 3.11.0-15-generic i686 Ubuntu 12.04.4 LTS auth_debug = yes auth_debug_passwords = yes auth_verbose = yes auth_verbose_passwords = yes disable_plaintext_auth = no listen = * log_path = /var/log/dovecot.log mail_debug = yes mail_location = maildir:~/Maildir mail_plugins = " quota" 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 ihave duplicate namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } plugin { quota = maildir:User quota quota_rule = *:storage=1G quota_rule2 = Trash:storage=+100M sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap sieve" service managesieve-login { inet_listener sieve { port = 4190 } } service managesieve { process_limit = 1024 } ssl = no ssl_cert = </etc/dovecot/private/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { driver = passwd result_failure = return-fail result_internalfail = return-fail result_success = continue-ok } userdb { args = username_format=%n /etc/dovecot/quotas driver = passwd-file result_failure = continue-ok result_internalfail = continue-ok skip = notfound } protocol imap { mail_plugins = quota }

[Dovecot] Disabling plus sign extension delimiter in lmtp listener (or userdb)
by Benoit Panizzon 01 Jun '14

01 Jun '14

Hello We have migrated our email services from a server, which did not support IMAP and folders, therefore threated the plus sign + as a normal character in a part of an email address. Our new server delivers the emails via lmtp to dovecot. the few users which got a + character in the username first could not log-in (fixed by adding + to auth_username_chars). Now the next problem turn out to be, that the lmtp listener stripps everything after the + sign. The MTA correctly sends the whole email address, so it's not the MTA's fault. It can easily be tested by connecting to the dovecot LMTP listener IP address by telnet: 220 grautvornix.imp.ch Dovecot ready. mail from:<nobody> 250 2.1.0 OK rcpt to:<b+enoit(a)iscan.ch> 550 5.1.1 <b+enoit(a)iscan.ch> User doesn't exist: b(a)iscan.ch I could not find any configuration parameters for the lmtp listener or userdb service to tell it what to do with the + sign. Did I miss something, or is it impossible to have the + sign accepted as a normal character in an email address? Kind regards -Benoit-

[Dovecot] Upgraded my dovecot?

I upgraded my server from Ubuntu 12.04LTS to 14.04LTS and it upgrade my dovecot too. Probably should have thought about that a little more before I pushed the button but oh well. So it didn't work when it came back up and I had to add a "inbox=yes" line to my namespace in 15-mailboxes.conf and that fixed it. So is there anything else I should update in my config files for this newer version of dovecot? # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-30-generic x86_64 Ubuntu 14.04 LTS auth_mechanisms = plain login mail_location = mbox:~/mail:INBOX=/var/mail/%u namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } protocols = " imap" service imap-login { inet_listener imaps { port = 0 } } service pop3-login { inet_listener pop3 { port = 0 } inet_listener pop3s { port = 0 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol imap { imap_capability = IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS mail_max_userip_connections = 30 } Thanks,

[Dovecot] ot: identifying TB IMAP issues
by voytek＠sbt.net.au 31 May '14

31 May '14

I have a user with with W7/TBird/IMAP to my dovecot 2.1.17 server, the user complains whilst he is composing lengthy emails (with multiple fowrds/replies quoted in the message) he gets 'hour glass' over compose windows with some message about not being able to save drafts, he then powers off ADSL modem, which enables him to continue composing email, powers on ADSL, and sends email what if anything can I assess at server end to identify any issues? any TB tips, what to enable or disable on TB ? looking at dovecot now (past the issue) with 'doveadm who' I don't see the user listed I think the user keeps many messages open concurrently in TB tabs, could that exhaust connection limit ? I expect this to be a TB issue? but, hope for some pointers

Hi there, We recently upgraded to 2.2.12 (the current version in FreeBSD's port tree), and are seeing these errors in our logs (not super frequently, but it happens): May 30 13:20:57 mail1 kernel: pid 15752 (imap), uid 1005: exited on signal 6 May 30 13:20:57 mail1 dovecot: imap(xxx): Fatal: master: service(imap): child 15752 killed with signal 6 (core not dumped - set service imap { drop_priv_before_exec=yes }) I tried manually upgrading to 2.2.13, on the off chance that was fixed, but I couldn't get the new pigeonhole (0.4.3) to compile once I did (perhaps why the FreeBSD port maintainer hasn't updated yet?). Suggestions? Right now we just check every couple of hours for affected users, and then delete all of the dovecot files for the affected user, which ends the error.

As others have intimated, the use of procmail as your LDA is causing your mailbox to become inconsistent with respect to your indices. Procmail is appending your messages to mailboxes, but is ignorant of the existence of dovecot indices, and does not update them. When your IMAP service access those mailboxes, it detects this condition, and that's the log messages you are seeing. I think those messages are benign -- you can probably ignore it. Dovecot will automatically rebuild them. The alternative is to let dovecot's be responsible for message delivery: it can then update the indices, and IMAP/POP will find consistent indices. Try this at the end of procmailrc for regular delivery to the INBOX ################################################################################ # Replace default action using dovecot-lda to maintains caches. ################################################################################ :0 w | /location/of/dovecot-lda -d $USER For for non-INBOX filtering, try something like :0 Hw *^Subject: TEST |/location/of/dovecot-lda -d $USER -m testbox Joseph Tam <jtam.home(a)gmail.com>

> * ^List-Id:.*users.lists.fedoraproject.org > | $DELIVER -m $DESTDIR/MLists/Fedora You removed the '-d' parameter -- it may or may not work without it, but you'll need it in a virtual user setup. I'm not sure whether procmail sets $USER by itself or it gets passed as an environment variable, so if $USER is not working, use $LOGNAME, or better yet, just hardcode the value if this is your own script. Also, the -m parameter is the name of a mailbox, not a pathname, so I think "MLists/Fedora" is what you want. > This is what I found in the procmail log: > lda: Fatal: destination user parameter (-d user) not given Well, this error couldn't be more explicit, can it?

[Dovecot] dovecot 2.1.15 hangs while connecting.
by Albert Whale 28 May '14

28 May '14

I am using Dovecot in two Server environments. My Legacy (5 years+ old) servers are running dovecot 1.1.20, and are responding as expected. These servers are using an NFS based storage for the /home directory structure, and are working beautifully. However, I need to replace these inefficient servers, and get more current. That brings me to the problem, where I am implementing Dovecot 2.1.15, which does not complete the authentication cycle. I have converted the 1.1.20 configuration using the documentation available, and I have the following for my running configuration (which is not working): # 2.1.15: /etc/dovecot/dovecot.conf # OS: Linux 3.8.13.4-server-1.mga3 i686 Mageia 3 auth_debug = yes base_dir = /var/run/dovecot/ disable_plaintext_auth = no lock_method = dotlock login_greeting = SpamZapper Email ready. login_log_format_elements = user=<%u> method=%m rip=%r lip=%l %c mail_debug = yes mail_fsync = always mail_location = maildir:~/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_privileged_group = mail mmap_disable = yes passdb { driver = pam } protocols = imap pop3 service auth { user = root } service imap-login { chroot = login client_limit = 256 user = dovecot } service pop3-login { chroot = login client_limit = 256 user = dovecot } ssl = no userdb { driver = passwd } verbose_proctitle = yes protocol pop3 { mail_max_userip_connections = 50 pop3_logout_format = top=%t/%p, retr=%r/%b, del=%d/%m, size=%s pop3_uidl_format = %08Xv%08Xu } protocol lda { postmaster_address = postmaster(a)example.com } I have captured the Debug output of the dovecot process while attempting to connect: May 27 13:02:10 ns dovecot: auth: Debug: client in: AUTH#0111#011PLAIN#011service=pop3#011session=IzAYqGT6pgBCz4Xk#011lip=66.207.133.227#011rip=66.207.133.228#011lport=110#011rport=38566#011resp=<hidden> May 27 13:02:10 ns dovecot: auth-worker(551): Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth May 27 13:02:10 ns dovecot: auth-worker(551): Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_mysql.so May 27 13:02:10 ns dovecot: auth-worker(551): Debug: pam(aewhale,66.207.133.228): lookup service=dovecot May 27 13:02:10 ns dovecot: auth-worker(551): Debug: pam(aewhale,66.207.133.228): #1/1 style=1 msg=Password: May 27 13:02:10 ns dovecot: auth: Debug: client passdb out: OK#0111#011user=aewhale May 27 13:02:10 ns dovecot: auth: Debug: master in: REQUEST#0112671116289#011453#0111#01174d85bf0d878139a83e682a869786da9 May 27 13:02:10 ns dovecot: auth-worker(551): Debug: passwd(aewhale,66.207.133.228): lookup May 27 13:02:10 ns dovecot: auth: Debug: master userdb out: USER#0112671116289#011aewhale#011system_groups_user=aewhale#011uid=501#011gid=501#011home=/home/aewhale May 27 13:02:10 ns dovecot: pop3-login: Login: user=<aewhale>, method=PLAIN, rip=66.207.133.228, lip=66.207.133.227 May 27 13:02:10 ns dovecot: pop3(aewhale): Debug: Effective uid=501, gid=501, home=/home/aewhale May 27 13:02:10 ns dovecot: pop3(aewhale): Debug: maildir++: root=/home/aewhale/Maildir, index=, control=, inbox=/home/aewhale/Maildir, alt= All processing stops here.

[Dovecot] Corrupted Mail?
by Arthur Dent 28 May '14

28 May '14

Hello All, I have a Dovecot v2.2.12 installation running on a Fedora 20 box which is the mailserver for my family. This means that it is serving only 4 accounts. I use fetchmail->procmail to feed Dovecot and I read my mail on clients such as Evolution on (another) Fedora 20 machine, iPad/iPhone or squirrelmail on the web (running on the same Fedora 20 server). The average mail throughput for the whole family is around a couple of hundred messages per day, but each (and every) day I get between 3 and 10 of the following messages: dovecot: imap(mark): Error: Next message unexpectedly corrupted in mbox file /home/mark/mail/MLists/Fail2Ban at 3407473: 1 Time(s) I have googled, but with little success. What I have found seemed to suggest that removing the .index files and allowing Dovecot to rebuild them will solve this. I did: find /home -type f -name "dovecot.index.*" -exec rm -f {} \; but it has made no difference. Can anyone help me solve this please? Thanks in advance Mark

[Dovecot] dsync changing source permission to "root" in backup mode
by Peter Mogensen 27 May '14

27 May '14

Hi, We have dsync failing once in a while when running in "backup" mode. What's strange is that the result is that the file permissions on the *source* machine ends up with the wrong permissions (set to uid 0). Even though the dsync manual clearly says: "Backup mails from default mail location to location2 (or vice versa, if -R parameter is given). No changes are ever done to the source location. Any changes done in destination are discarded." Running: 'dsync -R -o mail_home=/users/maildir backup ssh -c arcfour src-host "dsync -o mail_home=/users/maildir"' I know it's running as root, but even then ... it shouldn't modify the source in "backup" mode ?? The error message from dsync when failing is: dsync-remote(root): Error: Cached message size larger than expected (5292 > 5289) dsync-remote(root): Error: Maildir filename has wrong S value, renamed the file from /users/maildir/.Sent/cur/1381224782.M959810P3574.mail,S=5292,W=5411:2,S to /users/maildir/.Sent/cur/1381224782.M959810P3574.mail,S=5289:2,S dsync-remote(root): Error: Corrupted index cache file /users/maildir/.Sent/dovecot.index.cache: Broken physical size for mail UID 1040 dsync-remote(root): Error: dsync(dst-host): read(/users/maildir/.Sent/cur/1381224782.M959810P3574.mail,S=5292,W=5411:2,S) failed: Cached message size larger than expected (5292 > 5289) /Peter

[Dovecot] Segfault when deselecting virtual folder 2.2.13+ HG TIP
by Colin Knox 27 May '14

27 May '14

Hello, I'm seeing a segfault in the imap process with the current mercurial tip (including changeset 17382 e99cd21e1f92) when selecting a particular virtual mail folder (but no other virtual mailboxes) and then selecting a different mail folder as in the IMAP transcript below. The same segfaults are triggered with IMAP clients. The situation is worse with the 2.2.13 which segfaults when any virtual mailbox is deselected so the recent patch helps partially. Configuration summary, IMAP session in gbd including backtrace and virtual mailbox spec follow. Any ideas what's causing this?

[Dovecot] Odd ownership of the dovecot-uidlist file
by dclist.hook＠hook.net.nz 27 May '14

27 May '14

Hi, We have just recently switched from Courier to Dovecot for both IMAAP and POP access for our shared hosting platform, and while the issues we have been seeing with Courier have gone away a new one has popped up. Unfortunately googling for an answer is difficult as it falls into the ownership and permissions category which people seem to have all the time. But in those cases it always happens, whereas what we are seeing is a random ownership change on the dovecot-uidlist file. Basically what we see is the user is able to login fine for days and then all of a sudden the file has changed ownership to a user under a different domain, what's worse is the other user has not even logged in during that time. Here's a snippet from a case from a month ago which was escalated to us, there are plenty of other examples but its so random we only know its happened when the customer complains or we happen to watch the logs, the current help desk procedure when the customer calls is to just fix the ownership of the file. -- 8<-- Mar 25 11:18:05 brio dovecot: pop3-login: Login: user=<accounts@DOMAIN1>, method=PLAIN, rip=IP, lip=IP, mpid=21739, TLS, session=<mwQLnGH1ZAB2XalI> Mar 25 11:18:08 brio dovecot: pop3(accounts@DOMAIN1): Disconnected: Logged out top=0 (0 b), retr=4 (274142 b), messages=27 (10797760 b), del=0 Mar 25 11:19:24 brio dovecot: pop3(accounts@DOMAIN1): Error: open(/mnt/spool/keepers/t/DOMAIN1/accounts/Maildir/dovecot-uidlist) failed: Permission denied Mar 25 11:19:24 brio dovecot: pop3(accounts@DOAMIN1): Error: open(/mnt/spool/keepers/t/DOMAIN1/accounts/Maildir/dovecot-uidlist) failed: Permission denied -- 8<-- In this case the ownership of the file was: -rw------- 1 jacqui-30747 DOMAIN2 48839 Mar 25 10:31 dovecot-uidlist when it should be: -rw------- 1 accounts-25105 DOMAIN1 48839 Mar 25 10:32 dovecot-uidlist As you can see both the user and the group have changed to a different user as if that user had recreated the file. Its worth noting that the parent directory does not change: drwx------ 8 accounts-25105 DOMAIN1 4096 Mar 25 10:31 . so this user should not even be able to access this file. It would be great if someone can give us some hints where the problem maybe as this has us stumped.

Exim is writing to the Maildir with the correct permissions, and after fixing the ownership of the file dovecot can read and change the mailboxes. We do have a postlogin.sh script which runs after authentication to convert the old courier files over to the dovecot ones, this only happens however when the process has not run before (it appears dovecot deletes the files and recreates them, so we use a state file). Adding debugging to the script shows its running as the correct user at the last successful login. It does not run at all after the ownership has changed. There are some users who this is happening regularly, and other users who it has happened to only once. It is also not just limited to POP3, although this is where we commonly see it as dovecot accepts the IMAP connection if the ownership on a sub folders uidlist is different. If you need any further detail, I can provide it. Debugging could be much more difficult because of how random it is, while it can happen daily there have been periods of up to one week before its seen. Any help in finding this would be greatly appreciated, Cheers, Bruce

[Dovecot] Incorrect IMAP search results when FTS/Squat indexes are present with 2.1.7
by Robert L Mathews 27 May '14

27 May '14

We recently upgraded from Dovecot 1.2.15 (on Debian squeeze) to Dovecot 2.1.7 (on Debian wheezy/stable). For now, we continue to use FTS with Squat indexes. We'd like to eventually switch to Lucene but it's not yet supported in Debian stable. Since upgrading to 2.1.7, we've seen some problems with IMAP search results when an FTS Squat index is present (i.e., when the "dovecot.index.search" and "dovecot.index.search.uids" files are present). If it's present, even header searches sometimes give incorrect results (such as searches on FROM or SUBJECT headers). I'm wondering if this is a known issue with 2.1.7 and whether upgrading to a later version of Dovecot with Squat is likely to fix this (due to, say, <http://www.dovecot.org/list/dovecot-cvs/2012-June/020881.html>), or if Squat in all versions is a lost cause and I need to switch to Lucene. I can demonstrate the problem by showing the results of three searches on my mailbox. First, here are the correct results for header FTS searches when no "dovecot.index.search[.uids]" file is present: ---- . UID SEARCH FROM "Nick" * SEARCH 9 66 100 116 179 212 274 338 347 386 494 519 579 603 643 766 781 788 827 1107 1280 1626 1641 1667 1688 1702 1703 2184 2187 3202 3519 3716 3798 3885 3886 4024 4166 4345 4400 4401 4436 4491 4561 4595 4618 4676 4711 4712 4746 4788 4883 5217 5253 5577 5602 5722 .

[Dovecot] LDAP: allow pop3, restrict imap
by Andreas Schulze 26 May '14

26 May '14

Hello, I have all userdata in a ldapserver. Every user has the right to use pop3. There is no explicit attribute allowing that. It's simply possible. Now I like to add imap. For a starting period I like to restrict, who may use imap. http://wiki2.dovecot.org/Authentication/RestrictAccess mention a solution where I could modify ldap pass_filter. But that require an attribute "service=pop3" to be present in the ldap servers. In my case I have to add it for every existing user :-/ No way... Are there other options? Thanks, Andreas

[Dovecot] socket /var/spool/postfix/private/auth not created
by lister171254 26 May '14

26 May '14

I'm on Ubuntu 13.10 and followed these instructions http://wiki2.dovecot.org/HowTo/PostfixAndDovecotSASL to configure Dovecot for Postfix. No matter what I try, the listener is not created. <http://dovecot.2317879.n4.nabble.com/file/n48182/32.png> dovecot -n does not show the listener (I guess that's why its not created) This is the extract from the /etc/dovecot/conf.d/10-master.conf --------------- service auth { # auth_socket_path points to this userdb socket by default. It's typically # used by dovecot-lda, doveadm, possibly imap process, etc. Users that have # full permissions to this socket are able to get a list of all usernames and # get the results of everyone's userdb lookups. # # The default 0666 mode allows anyone to connect to the socket, but the # userdb lookups will succeed only if the userdb returns an "uid" field that # matches the caller process's UID. Also if caller's uid or gid matches the # socket's uid or gid the lookup succeeds. Anything else causes a failure. # # To give the caller full permissions to lookup all users, set the mode to # something else than 0666 and Dovecot lets the kernel enforce the # permissions (e.g. 0777 allows everyone full permissions). unix_listener auth-userdb { #mode = 0666 #user = #group = } # Postfix smtp-auth unix_listener /var/spool/postfix/private/auth { mode = 0600 user = postfix group = postfix } # Auth process is run as this user. #user = $default_internal_user } ---------------- Postfix is not involved in this right now as I expect the socket to be created when I restart dovecot. Can't find any meaningfull errors in the logs either. I hope I'm missing something obvious Thanks, Leo -- View this message in context: http://dovecot.2317879.n4.nabble.com/socket-var-spool-postfix-private-auth-… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Copies of outgoing emails in the Sent folder
by Dmitry Podkovyrkin 26 May '14

26 May '14

Hi! My mail server works in tandem: Dovecot (IMAP) + Postfix. How can I configure in Gmail: Outgoing email copied to the Sent folder using postfix without mail client? This question is for the mailing list for Postfix? Mail client itself copies outgoing messages in the folder Sent, but the messages are large, and the server is far away. And to transmit email twice for sending and copying is not effective. Sorry for my English ). -- Regards Dmitry Podkovyrkin mobile: +7 922 20 56 756 email: dmirty(a)rutelecom.company skype: dmitryrw

[Dovecot] Multilayer mail handling
by Jimmy Thrasibule 26 May '14

26 May '14

Hi, I'm wondering what is the correct architecture and configuration to setup a multilayer mail handling? What I have in mind is something more like what we can found in Web platform architectures. 1. First layer does first checks: user authentication and SSL offloading. If all checks are OK request is proxied to layer 2. 2. Second layer, will actually handle the IMAP/POP3 connection proxied by layer 1, no major checks should be done as already made by layer 1. 3. Finally, layer 3 to do some virus checks on the emails and maybe some other things I can't think about. Do you have some pointers on how to set up such a mail stack where each layer can be on multiple other hosts? Best regards, Jimmy

[Dovecot] Index cache errors worse with 2.2.x
by Alexander 'Leo' Bergolth 25 May '14

25 May '14

Hi! I am getting "Cached message size smaller than expected" errors since dovecot-2.1.x. Until now, I thought that those errors don't do any harm, I assumed that the cache will just be rebuilt after the error had been detected. However, since dovecot 2.2.x (I tried 2.2.7 and 2.2.10), the errors sometimes seem to actually cause mail access to fail. With dovecot-2.1.1, only the first two messages were logged, since using 2.2.7 and 2.2.10, the "read ... failed: Invalid argument" sometimes appear: -------------------- 8< -------------------- May 7 17:03:52 samba dovecot: imap(xyz): Error: Cached message size smaller than expected (2246 < 2247) May 7 17:03:52 samba dovecot: imap(xyz): Error: Corrupted index cache file /home/xyz/mail/.imap/INBOX/dovecot.index.cache: Broken physical size for mail UID 11277 May 7 17:03:52 samba dovecot: imap(xyz): Error: read(/var/mail/xyz) failed: Invalid argument May 7 17:03:52 samba dovecot: imap(xyz): Error: read(/var/mail/xyz) failed: Invalid argument (uid=11277) -------------------- 8< -------------------- I am using dovecot on RHEL6 with mbox mailboxes.

[Dovecot] dsync incredibly slow
by Alan McGinlay 23 May '14

23 May '14

Hi! While performing a dsync from cyrus imap to dovecot 2.2.12, dsync seems to stop for perhaps a minute without disk / cpu / memory activity (that I can see). This happens several times per sync per user so it takes an enormous amount of time to sync just a couple of gigs of mail. dsync -D -v -o mail_fsync=never mirror -f -R -u user(a)example.com imapc: What could possibly be the cause of this slowness? Is it protocol dependent or just dsync it's self? Thanks!

[Dovecot] Dovecot ontop of glusterfs issue.

Hey, I am testing Glusterfs as a storage backend for dovecot as a LDA and imap server. I have seen similar lines in the logs to these: May 21 10:46:01 mailgw dovecot: imap(eliezer(a)ngtech.co.il): Warning: Created dotlock file's timestamp is different than current time (1400658105 vs 1400658361): /home/vmail/ngtech.co.il/eliezer/Maildir/.Mailing_lists.ceph_users/dovecot-uidlist May 21 10:46:01 mailgw dovecot: imap(eliezer(a)ngtech.co.il): Error: Transaction log /home/vmail/ngtech.co.il/eliezer/Maildir/dovecot.index.log: duplicate transaction log sequence (2713) The volume is mounted only by one server with ubutntu 14.04. I have seen threads and posts about similar issue with nfs. I want to try to debug the issue but note that with the same settings of the server nfs worked fine but slower. dovecot -n output: http://pastebin.centos.org/9626/ The glusterfs is a replicated volume constructed of two bricks which is mounted only on one dovecot server. All three servers are using the same ntp pool and are synced. Any direction is better then the state I am now. Thanks, Eliezer

[Dovecot] director with same director / backend servers
by Will Yardley 22 May '14

22 May '14

I know this has been covered somewhat, but I'm still not totally clear. I'm trying to setup a 3 node cluster with 3 directors and 3 backend systems. This post (from 2012) suggests that proxy_maybe should work with director: http://www.dovecot.org/list/dovecot/2012-December/069806.html However, these two posts (from 2013) seem to say that it will not: http://dovecot.org/pipermail/dovecot/2013-November/093776.html http://dovecot.org/pipermail/dovecot/2013-November/093809.html When I try to just set =proxy_maybe=y in my LDAP config's pass_attrs, and not have an explicit 'director' listener for pop3-login / imap-login, it complains about lack of a host. May 22 14:28:08 XXXX dovecot: pop3-login: Error: proxy: host not given: user=<XXXXXXX>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Guessing the answer is "no", but is there any way (with v 2.x) to have one regular "listener" for imap / pop3, and one "director" listener for each as well, using the same instance of Dovecot? Has anyone gotten this to work successfully? I'm using LDAP, and do not want to explicitly specify a host for each username, I just want director to balance users across the 3 hosts. Obviously, I can just create two instances, but not only does this make the config more convoluted (especially following the convention of having the config files broken out into a bunch of files), but means I have to modify the default init script to really do it cleanly (something we were doing on the older iteration of this system that I had really been hoping to avoid). I'm assuming it's not possible to simply have the listeners for 'foo-login' execute something different depending on the port? I tried a couple different ways of configuring this, but it didn't seem to work. Dovecot is version 2.0.9 from RHEL 6. w

[Dovecot] Dovecot pam
by Tommy Berglund 22 May '14

[Dovecot] When the subject portion of an e-mail contains a control character, dovecot.sieve terminates unexpectatedly.
by Atsuko Tanaka 22 May '14

22 May '14

Hello. We have currently set dovecot.sieve to insert the text "[SPAM]" at the beginning of an e-mail's subject when it's X-Spam-Score is above 80%. After we set our system as stated the following errors occur: 1) When an e-mail's subject contains control characters like [Ctrl+V|^V], dovecot.sieve terminates with an error and an e-mail is not able to be sent. When a MIME encoded Subject like [ＴＥＳＴ^VＭＡＩＬ] is sent we're not able to edit the subject and dovecot ends with an error. This is a sample of the data that was used in testing. Subject: =?ISO-2022-JP?B?GyRCI1QjRSNTI1QbKEIWGyRCI00jQSNJI0wbKEI=?= X-Spam-Score: 100.00% ↓ Subject: =?ISO-2022-JP?B?GyRCI1QjRSNTI1QbKEIWGyRCI00jQSNJI0wbKEI=?= X-Spam-Score: 100.00% This is the log generated by the data above. ---------------------------------------------------------------------- sieve: info: started log at May 02 10:46:22. main script: line 14: error: addheader action: specified value `[SPAM] ＴＥＳＴ?・・' is invalid. ---------------------------------------------------------------------- Aside from [Ctrl + V] the following control charcters also cause errors: backspace Ctrl + A Ctrl + C Ctrl + [ Ctrl + X Ctrl + Y 2) When an e-mail's subject line contains a "\0" character, everything following the null character is deleted. When a MIME encoded Subject is sent, for example "ＴＥＳＴ\0ＭＡＩＬ", the subject becomes "[SPAM]ＴＥＳＴ", the characters after the NULL character are deleted and dovecot.sieve ends normally. This is a sample of the data that we collected.

[Dovecot] Sieve fileinto extension and redirect action
by FUSTE Emmanuel 21 May '14

21 May '14

Hello, Is there any way to limit the use of the "redirect" action (local user only or silent ignore) as provisioned by the RFC in the Pigeonhole implementation ? The only way I found for the moment is to completely disable the fileinto extension which hardly beat the users experience. "redirect" is forbidden by my organization policy. Regards, Emmanuel.

[Dovecot] LMTP hostname ignoring ENV variables
by G H 21 May '14

21 May '14

I am having an issue with LMTP appending the local hostname to received mail from Postfix. I either want to append localhost, a custom string, or nothing at all. Looking through the source code, I believe I should be able to set "export DOVECOT_HOSTNAME" and "export DOVECOT_HOSTDOMAIN" in my initscript to override the hostname set in lmtp/commands.c, client_get_added_headers() I'm using Centos 5; my hostname is mailtest1.atest.qq -- it is not defined in /etc/hosts. The added header is below: Received: from mail.mailorxyz.de by mailtest1.atest.qq (Dovecot) with LMTP id sreUK1+sfFOseQAAPYI4hw for <admin(a)mailorxyz.de>; Wed, 21 May 2014 13:39:03 +0000 Received: by mail.mailorxyz.de (Postfix, from userid 97) id CC743116AB5; Wed, 21 May 2014 13:39:03 +0000 (UTC) I have the following defined in /etc/init.d/dovecot: export DOVECOT_HOSTDOMAIN=dovecot.mailorxyz.de export DOVECOT_HOSTNAME=dovecot.mailorxyz.de Am I missing something or did I misunderstand the source code? Thanks.

Hi Again, we have one domain, i suppose we don't have any problem with %n parameter. our mail server has mapped LUN Storage disk , we have some empty space problems, so i think it's better keep user things in storage for backup etc. we have totally 40K users(most of students) but i think at most 50 of them use this filter, autorespond etc. :) thank you for your reply.

Please explain the following dovecot (2.2.13) behaviour: I run dovecot in ldap auth debug mode and log file excerpt follows: 2014-05-21T08:22:01+02:00 dovecot/ip dovecot: auth: Debug: ldap(user@domain,pcip,<bdKvA+P5HQCbnmFI>): bind search: base=o=tree,dc=do,dc=ma,dc=in filter=(&(objectClass=MailAccount)(accountActive=TRUE)(mail=user@domain)) 2014-05-21T08:22:01+02:00 dovecot/ip dovecot: auth: Debug: ldap(user@domain,pcip,<bdKvA+P5HQCbnmFI>): result: mail=user@domain; mail unused 2014-05-21T08:22:01+02:00 dovecot/ip dovecot: auth: Debug: ldap(user@domain,pcip,<bdKvA+P5HQCbnmFI>): result: mail=user@domain 2014-05-21T08:22:01+02:00 dovecot/ip dovecot: auth: Debug: client passdb out: OK 24 user=user@domain 2014-05-21T08:22:01+02:00 dovecot/ip dovecot: auth: Debug: ldap(user@domain,pcip,<bdKvA+P5HQCbnmFI>): user search: base=o=tree,dc=do,dc=ma,dc=in scope=subtree filter=(&(objectClass=MailAccount)(accountActive=TRUE)(mail=user@domain)) fields=mail,quota,mailbox 2014-05-21T08:22:01+02:00 dovecot/ip dovecot: auth: Debug: ldap(user@domain,pcip,<bdKvA+P5HQCbnmFI>): result: mailbox=maildir:/mail/domain/user/mail/ quota=1G mail=user@domain; mail,mailbox,quota unused 2014-05-21T08:22:01+02:00 dovecot/ip dovecot: auth: Debug: ldap(user@domain,pcip,<bdKvA+P5HQCbnmFI>): result: mailbox=maildir:/mail/domain/user/mail/ quota=1G mail=user@domain 2014-05-21T08:22:01+02:00 dovecot/ip dovecot: auth: Debug: master userdb out: USER 3606315009 user@domain quota_rule=*:bytes=1G mail=maildir:/mail/domain/user/mail/ home=/mail/domain/user Question: why are there two ldap result log lines while the first line shows unused attributes and the second doesn't. Does the first occurence show some code being excessive somehow? Thanks. MU

[Dovecot] allow_nets + default + ldap
by Andreas Schulze 21 May '14

21 May '14

Hello, I'm playing with allow_nets function. It is really cool! In a filebased passwd backend you simply add "allow_nets=192.0.2.143/32" as mentioned in http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/AllowNets But if I use an LDAP backend it looks different. Following http://wiki2.dovecot.org/AuthDatabase/LDAP/AuthBinds and http://wiki2.dovecot.org/AuthDatabase/LDAP/Userdb#Attribute_templates_.28v2… my pass_attrs looks this: pass_attrs = =user=%{ldap:uid}, \ =allow_nets=%{ldap:allownets} Using this syntax I could add an attribute "allownets" in the ldapserver to limit access for a user. A problem occour if the attribute is not present. For example if a user should not be limited or only some but not any user should be limited. So I extend my pass_attrs with a default. pass_attrs = =user=%{ldap:uid}, \ =allow_nets=%{ldap:allownets:10.0.0.0/8} Again, that's fine. Any user was allowed to connect from my private network. But then some users connect via ipv6. I tried to extend my default to pass_attrs = =user=%{ldap:uid}, \ =allow_nets=%{ldap:allownets:10.0.0.0/8,fec0::/16} That syntax, a comma separated list, produces errors no matter if quoting using " or ' or no quoting at all. So I looked at the source (thanks, it's open!) and wrote a little patch to allow simple defaults: - ALL -> allow any address - NONE -> deny any address Now I could write pass_attrs = =user=%{ldap:uid}, =allow_nets=%{ldap:allownets:ALL} or pass_attrs = =user=%{ldap:uid}, =allow_nets=%{ldap:allownets:NONE} to allow or deny any ldap account not having an attribute allownets. Maybe there are other solutions, but that's my way... Andreas
