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 13 Jun '14

13 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
