[Dovecot] Design: Adding checksums to index files
by Timo Sirainen 05 Aug '13

05 Aug '13

I've been planning on adding these for years. Maybe it's about time soon. I guess they could be added already to v2.2, but enabled only by a new setting because it requires file format changes that old Dovecots can't then read. I could probably patch v2.1 also so it is able to at least read the new format without failing. For v2.3 this new format could then be made the default. And what would the checksums be exactly? Would the standard CRC32 and CRC8 work fine, or are there any better ones? 1. dovecot.index v2.1+ always only fully recreates this file, never overwrites data to it. So the checksums could be written only when the dovecot.index is being recreated. There are 3 possible things to checksum: - header (32bit checksum) - all of the mail records (32bit checksum) - each mail record independently (8bit checksum per mail) The header's checksum could be verified every time the index is opened. The full mail record checksum could be verified when something appears to be wrong, but it's probably a waste of time to check it in normal operation. I'm not really sure about the per-mail checksums. It would be easy to create them while dovecot.index is being created, but after reading the file into memory the records are updated in many ways in many places. It's probably not worth the complexity and extra slowness to verify and/or update the checksums in all the different places. So is it worth it to even have them? In error conditions when fixing up indexes it could be useful to skip over records with broken checksums (and check if the mail is in dovecot.index.backup with correct checksum). Maybe that's enough to be worth 1 byte per message?.. 2. dovecot.index.log This file is only appended to. Each committed transaction could be prefixed in the new format with <transaction size><transaction 32bit checksum>. With the new format this wouldn't actually increase the log file size much, because there is already some space wasted for a compatibility "boundary" record that could be removed now. 3. dovecot.index.cache Cache file is the most complex file. Its headers get overwritten once in a while. Probably not worth the trouble to checksum the header itself, and there's not a lot that could be done even if a broken checksum was found. But each mail_cache_record could have its own checksum. A 8bit checksum could be added without increasing the file's size. Maybe that would be enough? 4. dovecot.index.thread This is a rather simple file and a 32bit checksum could be added to its header, and verified every time the file is read (because it's fully read anyway). 5. dovecot.mailbox.log This file doesn't even have a header. There are 3 unused bytes in each record currently. One of them could be used for a new "flags" parameter, with the only flag being "checksum added". There would still be space left for 8bit or 16bit checksum. 6. Other files There are also some text files, like dovecot-acl, subscriptions, quota usage and Sieve scripts. They probably have to be without checksums for now.

[Dovecot] How to configure sendmail using dovecot lmtp
by alfdc 05 Aug '13

05 Aug '13

Hi, I can't seems to find any posting on how to configure sendmail to use dovecot as lmtp. All I see is using it as LDA. I am particularly interested on how to tell sendmail to ask dovecot to deliver the message to the user. In the wiki for lda it says to add the following in the sendmail config: FEATURE(`local_procmail', `/usr/local/libexec/dovecot/deliver',`/usr/local/libexec/dovecot/deliver -d $u') MODIFY_MAILER_FLAGS(`LOCAL', `-f') MAILER(procmail) Is this the same for lmtp? If so how does it know when to use lda or lmtp? Beside, is procmail playing any role in any of these? Can the I just replace the whole thing as: FEATURE(`local_lmtp',`/usr/local/libexec/dovecot/deliver',`/usr/local/libexec/dovecot/deliver -d $u) MAILER(`local') Thanks. -- View this message in context: http://dovecot.2317879.n4.nabble.com/How-to-configure-sendmail-using-doveco… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Antispam folder names
by Jost Krieger 05 Aug '13

05 Aug '13

Is there anywhere a collection of folder names for the antispam_trash and antispam_spam configuration? Our problem is that in academia, you have a vast amount of different clients, and some, like Microsoft, use language-specific folder names *on the server*. So we're now collecting folder names to better handle the rare cases. Two more problems: 1. We needed to fix UTF-8 handling in the plugin, so that we kow canb say antispam_trash_pattern_ignorecase = gelöscht* in place of :set sp antispam_trash_pattern_ignorecase = gel&APY-scht* 2. Some clients allow prefixing the IMAP folders with a fixed name, often "INBOX". So we would like to specify something like antispam_trash_pattern_ignorecase = Junk*;*/Junk* which is not supported.

[Dovecot] Fileoperations in Maildir – problematic or okay?
by Martin Burgraf 05 Aug '13

05 Aug '13

Hi, I'm wondering: Is it a problem to move and delete files inside a dovecot-managed maildir? For example: I have a folder ~/.maildir/.Sub1.Start/cur and a folder ~/.maildir/.Sub1.Start.old/cur and like to regularly move old mails from the first to the second one. Can you create a cron job saying something like: find ~/.maildir/.Sub1.Start/cur -mtime +5 -exec mv {} ~/.maildir/.Sub1.Start.old/cur \; ? I guess this would be some sort of problem, wouldn't it? IIRC dovecot keeps indexes of the files inside a folder and moving them around like this may confuse the software, am I right? bye Martin

[Dovecot] ./configure dovecot
by LuKreme 03 Aug '13

03 Aug '13

When I do a ./configure in dovecot (2.2.1) I get this notice (first line): configure: WARNING: you should use --build, --host, --target Then, much later on: checking sys/ucred.h presence... yes configure: WARNING: sys/ucred.h: present but cannot be compiled configure: WARNING: sys/ucred.h: check for missing prerequisite headers? configure: WARNING: sys/ucred.h: see the Autoconf documentation configure: WARNING: sys/ucred.h: section "Present But Cannot Be Compiled" configure: WARNING: sys/ucred.h: proceeding with the compiler's result configure: WARNING: ## ---------------------------------- ## configure: WARNING: ## Report this to dovecot(a)dovecot.org ## configure: WARNING: ## ---------------------------------- ## checking for sys/ucred.h... no at the end I get: configure: creating ./config.status Install prefix . : /usr/local File offsets ... : 64bit I/O polling .... : kqueue I/O notifys .... : kqueue SSL ............ : yes (OpenSSL) GSSAPI ......... : no passdbs ........ : static passwd passwd-file pam checkpassword : -shadow -bsdauth -sia -ldap -sql -vpopmail userdbs ........ : static prefetch passwd passwd-file checkpassword nss : -ldap -sql -vpopmail SQL drivers .... : : -pgsql -mysql -sqlite Full text search : squat : -lucene -solr but there is no makefile created. ./configure --help just runs the configure script again, and none of --build --host or --target have any effect on the errors shown, including the first line error. So I think, ok, fine, I'll grab the latest build (2.2.4). Same result. OK, fine. Let's look at 1.2.17. Same thing, only without the cured.h warning. Still the same error on the first line after ./configure and still no make file. There's no big flashing warning anywhere that I can see that says, "Hey, dummy, this isn't going to work." config.log even ends with a "configure: exit 0" (The system already has dovecot 1.2.17 installed, but I was looking at installing $LATEST). -- May you live in interesting times

[Dovecot] Mail being delivered but MUA showing empty inbox

Dovecot : 2.0.19 (see config at http://pastebin.com/raw.php?i=KMaQ9Ccc) Postfix : 2.9.6 (see config at http://pastebin.com/raw.php?i=EEeevHfk) I'm trying to get Dovecot and Postfix working on Ubuntu 12.04LTS but am not having much luck.

[Dovecot] system_groups_user syntax especially in LDAP
by ray klassen 02 Aug '13

02 Aug '13

so if possible, I'd like an example of how to include system_groups_user in the userdb setup. I'm using ldap, but I could revert to using pam on ldap. There is a ldap query (gleaned from smbldap-tools) that will return a list of groups for a user (&(objectclass=posixGroup)(memberuid=%u)) but I don't know if the ldap driver will handle it but above all I can't figure out how it fits into the dovecot configuration! I'm trying to get Dovecot 2.1.7 on debian wheezy to recognize shared folders that have group ownership.

[Dovecot] Lowering Log Levels Back to Defaults
by Asai 02 Aug '13

02 Aug '13

Greetings, I'm sorry for asking what may be a really obvious question, but I'm having a hard time turning off logging, or at least getting less verbose logging. My dsync logs are about 7 MB daily, and I'm trying to get that switched off. At one point I had it on a lower level of verbosity, and I turned it up for debugging purposes, but now I cannot seem to turn it back down, which is something I did many times before. For example the logs are getting tons of Info level messages. dsync(asai(a)globalchangemusic.org): Info: expunge: box=Trash, uid=61625, msgid=<JIRA.14456.1367259371732.1046.1367259384800@hexagon>, size=9586 In dovecot.conf I have commented out the following include, which used to lower the log levels back to the defaults, but I've upgraded Dovecot recently to 2.2.4 from 2.1 something: #!include conf.d/10-logging.conf I had the default levels raised in that config file. I'm not sure this helps but: [vmail@triata ~]# doveconf -n # 2.2.4: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-194.32.1.el5xen x86_64 CentOS release 5.5 (Final) ext3 auth_mechanisms = plain login mail_home = /vmail/%d/%n/home mail_location = maildir:/vmail/%d/%n mail_plugins = " mail_log notify" 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 namespace { inbox = yes location = prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } plugin { sieve = /vmail/%d/%n/sievescript } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { group = vmail mode = 0660 user = vmail } unix_listener auth-userdb { mode = 0660 user = vmail } user = root } service imap-login { process_min_avail = 3 service_count = 0 vsz_limit = 0 } ssl_cert = </etc/postfix/ssl/triata.globalchangemultimedia.net.pem ssl_key = </etc/postfix/ssl/triata.key userdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } protocol lda { hostname = triata.globalchangemultimedia.net mail_plugin_dir = /usr/lib64/dovecot/ mail_plugins = sieve postmaster_address = postmaster(a)globalchangemultimedia.net } protocol imap { imap_idle_notify_interval = 24 mins mail_max_userip_connections = 60 } -- --Asai

[Dovecot] Custom quota setup
by Richard Platel 02 Aug '13

02 Aug '13

(Dovecot 2.2-ee) We have a weird quota requirement, we have file storage that we manage through our own APIs but want that usage to come out of the user's mail quota. The usage is in a maildirsize like file uncreatively called filestoresize in the user's maildir. In the past we've been doing this by modifying the quota plugin and re-compiling, but it seems like it should be possible to do this via configuration. Is there a way to add a quota setting pointing at this file for additional usage (not limits)? The feature is used infrequently so it would probably be acceptable use the dirsize backend, but I can't figure out how to configure that to point at a certain directory. We pass custom quota rules for each user in our userdb, and use a custom dict proxy program, so that program could read the file and pass a setting at log in time too (if, for example, there was a setting that said "offset the user's quota usage by X amount") Thanks.

We do our own password auth (so we can support custom hash types, etc). I've only a private version of a HTTP-based passdb implemented for a customer.

[Dovecot] 2.2.4 - Some questions about and needing help with quota-status
by Axel Luttgens 02 Aug '13

02 Aug '13

Help! I'm stuck. :-( The config of my experimental setup appears at the end of this message; I'm providing hereafter some more info that may not be immediately obvious. This is dovecot 2.2.4 with changesets 9091d0f2d971 and 2be295a0b64f. All involved databases are sqlite ones. passdb and userdb are devised so as to change usernames. For example, I could have a user with addresses "doe(a)oldexample.com", "johnd(a)oldexample.com" and "john.doe(a)example.com" needing to be able to log in as "jdoe" or "u123456"; all db lookups for that user then end with name "john.doe". This is a single mail user setup (user/group "dovemailer", uid/gid 999). Service lmtp has been configured to run as that user; that required a slight adjustment at the auth-userdb socket level. As a general rule, the quota dict appears to be correctly updated upon message arrivals and removals (thru lmtp, pop, imap), and to be correctly queried/interpreted by the various parts of the server. For example, thru the userdb query, user john.doe has been given an even lower quota limit than the already low default defined for testings: $ sudo doveadm quota get -u john.doe Quota name Type Value Limit % Quota utilisateur STORAGE 20 5 400 Quota utilisateur MESSAGE 14 - 0 and is clearly recognized as being over-quota by lmtp: $ telnet /_ROOT/var/run/dovecot/lmtp Trying /_ROOT/var/run/dovecot/lmtp... Connected to (null). Escape character is '^]'. 220 almba.local Dovecot ready. mail from:<mary.jane(a)example.com> 250 2.1.0 OK rcpt to:<john.doe(a)example.com> 250 2.1.5 OK data 354 OK Subject: test . 552 5.2.2 <john.doe(a)example.com> Quota exceeded (mailbox for user is full) Note that both services config and dict are launched if they aren't running. Since it has been previously seen that running quota-status as root comes with its own problems, and since it is a single user setup anyway, I'm trying to run it as dovemailer as well. So, let's try to see what quota-status thinks about john.doe: $ sudo -u _postfix telnet /_ROOT/var/spool/postfix/private/quota-policyd Trying /_ROOT/var/spool/postfix/private/quota-policyd... Connected to (null). Escape character is '^]'. Connection closed by foreign host. Clearly, not much... Looking in the log: dovecot[10554]: quota-status: Fatal: Error reading configuration: net_connect_unix(/_ROOT/var/run/dovecot/config) failed: Permission denied This thus raises a first question: Q1. What makes lmtp and quota-status different? How does lmtp manage to fetch all needed info, while quota-status seems to require an access to the config socket? Let's then slightly adjust dovecot.conf, in the hope to make quota-status happy: service config { unix_listener config { group = dovemailer mode = 0660 } } Q2. Should the above really be needed, wouldn't there be a better way? I ask, because it seems to me that I'm starting to seriously lose the benefits of privilege separation...

[Dovecot] mails delivered to the wrong user when using lmtp_proxy and reject_unverified_recipient
by Peer Heinlein 02 Aug '13

02 Aug '13

Hi, looks like we detected a serious bug in dovecot's lmtp proxying where e-mails are delivered to the wrong user. The setup is: *) Dovecot is configured with "lmtp_proxy=yes" # Support proxying to other LMTP/SMTP servers by performing passdb lookups. lmtp_proxy = yes *) Postfix uses "dynamic recipient verification", so Postfix starts sending a (verify) mail by LMTP to dovecot, but quits the lmtp-session right after the RCPT TO:. No DATA-stage is reached in the protocol and no real e-mail is sent. But Postfix had a LMTP-connection for "user1". *) Just some seconds later a "real" e-mail to "user2" has to be delivered to dovecot by LMTP. But Dovecot will deliver this mail to the wrong "user1" instead of "user2". Looks like dovecot re-uses the (still opened?) lmtp-proxy-connection from "user1" to deliver an e-mail to "user2". Have a log at the protocol: 1) There's a verify call to user1 from Postfix: Jul 19 13:49:49 mailms postfix/lmtp[9842]: DE653280C51: to=<user1(a)example.com>, relay=localhost[127.0.0.1]:24, conn_use=2, delay=120, delays=117/0.45/0/2.5, dsn=2.1.5, status=deliverable (250 2.1.5 OK) 2) Just five seconds later the e-mail to user2 (see Postfix' point of view in the last line) is delivered to user2 (see result from Dovecot in the last line): Jul 19 13:50:04 mailms dovecot: lmtp(10965, kraemer): save: box=INBOX, uid=49880, msgid=<59798276-E5D1-4053-A570-9901B731DF5D(a)example.come>, size=11020 Jul 19 13:50:04 mailms dovecot: lmtp(10965, kraemer): 1zTeKrMn6VHVKgAAhyqEuA: msgid=<59798276-E5D1-4053-A570-9901B731DF5D(a)example.com>: saved mail to INBOX Jul 19 13:50:04 mailms postfix/lmtp[10953]: C25FC280BE5: to=<user2(a)example.com>, relay=localhost[127.0.0.1]:24, conn_use=19, delay=116, delays=115/0.53/0/0.33, dsn=2.0.0, status=sent (250 2.0.0 <user2> 1zTeKrMn6VHVKgAAhyqEuA Saved) Same with user3 and user4: Jul 19 14:47:53 mailms postfix/lmtp[10845]: C389A2809D7: to=<user3(a)example.com>, relay=localhost[127.0.0.1]:24, delay=4.7, delays=3.7/0.87/0/0.19, dsn=2.1.5, status=deliverable (250 2.1.5 OK) Jul 19 14:47:55 mailms dovecot: lmtp(26546, fs211113): save: box=INBOX, uid=8504, msgid=<928729810.113.1374238063381(a)example.com>, size=233151 Jul 19 14:47:55 mailms dovecot: lmtp(26546, fs211113): MbMvI2816VGyZwAAhyqEuA: msgid=<928729810.113.1374238063381(a)example.com>: saved mail to INBOX Jul 19 14:47:55 mailms postfix/lmtp[22524]: 6F0D2280A6E: to=<user4(a)example.com>, relay=localhost[127.0.0.1]:24, conn_use=2, delay=10, delays=8.4/1/0/0.8, dsn=2.0.0, status=sent (250 2.0.0 <user3> MbMvI2816VGyZwAAhyqEuA Saved) The user itself is quite normal in the user database (but has a mailhost=127.0.0.1 set): root@mailms:/etc/dovecot/conf.d# doveadm user user2(a)example.com userdb: user2(a)example.com uid : 5000 gid : 5000 home : /srv/mail/user2 root@mailms:/etc/dovecot/conf.d# doveadm auth user2(a)example.com Password: passdb: user2(a)example.com auth failed extra fields: user=user2 Peer -- Heinlein Support GmbH Schwedter Str. 8/9b, 10119 Berlin http://www.heinlein-support.de Tel: 030 / 405051-42 Fax: 030 / 405051-19 Zwangsangaben lt. §35a GmbHG: HRB 93818 B / Amtsgericht Berlin-Charlottenburg, Geschäftsführer: Peer Heinlein -- Sitz: Berlin

[Dovecot] Auth-woker log lines
by Grzegorz Staniak 02 Aug '13

02 Aug '13

Hi, Are log lines like the following: Jul 28 15:30:50 mx1.somewhere dovecot: auth-worker(18980): sql(user(a)domain,217.67.x.x): unknown user Jul 28 15:32:56 mx1.somewhere dovecot: auth-worker(18980): sql(user(a)domain,212.182.x.x): Password mismatch written every time any authetntication phase fails, in SASL as well as in POP3/IMAP mailbox access? I have a legacy app that would gain a lot if I could distinguish between failed SASL authentication and failed POP3/IMAP authentication. I know I can use the "auth failed" lines for the latter case, and postfix log lines in the former, but they don't contain user info. Is there a way for log monitoring software to get failed login lines with both user info, and the reason (SASL, POP3, IMAP)? Regards, -- Grzegorz Staniak <gstaniak [at] gmail _dot_ com>

[Dovecot] 2.2.4 - quota-status changing the user it is running as
by Axel Luttgens 02 Aug '13

02 Aug '13

Hello, I'm currently experimenting with this quota-status service configuration: service quota-status { client_limit = 1 executable = quota-status -p postfix # Let's make the default explicit. user = root unix_listener /var/spool/postfix/private/quota-policyd { user = postfix } } The idea is to run the service as root during the preliminary tests (at worst, since the service is going to be used as a policy daemon by Postfix only, it shouldn't be very problematic to have it running as root anyway). A user, with address john.doe(a)example.com and identified as john.doe, is known to be over-quota. A "doveadm quota get" returns: $ sudo doveadm quota get -u john.doe Password: Quota name Type Value Limit % Quota utilisateur STORAGE 5 5 100 Quota utilisateur MESSAGE 9 - 0 and messages for that user are correctly rejected by lmtp: dovecot[4989]: lmtp(5069, john.doe(a)example.com) QWSWLgrP4lF7FAAA5Q0ykw: msgid=<20130714161643.9085DF176F2(a)ALMba.local>: save failed to INBOX: Quota exceeded (mailbox for user is full) Let's now simulate a connection from Postfix: $ sudo -u postfix telnet /_ROOT/var/spool/postfix/private/quota-policyd Trying /_ROOT/var/spool/postfix/private/quota-policyd... Connected to (null). Escape character is '^]'. A look at the output of top (excerpt) confirms that quota-status is running as root: PID COMMAND UID 5100 quota-status 0 Going on with our telnet session: recipient=john.doe(a)example.com size=10000 action=OK Hmmm... OK, this may be a config problem of mine which may require further investigation. Anyway, looking at top's output: PID COMMAND UID 5100 quota-status 999 it appears that quota-status is now running as the mail_uid/mail_gid user; the switch happens immediately after having entered the empty line in the telnet session. Let's then try to go further within the telnet session: recipient=john.doe(a)example.com size=10000 action=DEFER_IF_PERMIT Internal error occurred. Refer to server log for more information. ^] telnet> quit Connection closed. and a look at the log indeed reveals that quota-status doesn't have sufficient privileges anymore: dovecot[4989]: quota-status(john.doe(a)example.com): Error: user john.doe(a)example.com: Error reading configuration: net_connect_unix(/_ROOT/var/run/dovecot/config) failed: Permission denied Is this the expected behavior, to have quota-status switch to another user? TIA, Axel

[Dovecot] [PATCH] quota-status: allow different action for messages that are too large (over maximum quota)
by Ulrich Zehl 02 Aug '13

02 Aug '13

This proposed patch to quota-status allows the administrator to return different actions for messages that (a) cannot currently fit in the quota (because there's not enough free space) and (b) are over the maximum quota limit (and could not even be delivered if the mailbox was empty). Configuration works like this: plugin { quota_status_overquota = DEFER_IF_PERMIT 4.2.2 Mailbox full quota_status_toolarge = REJECT 5.2.3 Message length exceeds administrative limit } The patch is backwards compatible: If quota_status_toolarge is not set, quota_status_overquota is returned. No changes are necessary in setups where the new feature is not desired. The reason I developed this patch is: In my environment, I have mostly POP3 mailboxes, where condition (a) changes frequently (usually after each login), but condition (b) will almost never change (users do not get additional mailbox space often). Thus, I'd like to avoid bouncing mails that could be delivered half an hour later. This patch works for 2.2 and 2.1. (This assumes you have already applied the trivial patch I sent earlier; otherwise patch(1) will report some fuzz.) What do you think of this?

[Dovecot] misconception in uid and gid
by Felix Rubio Dalmau 02 Aug '13

02 Aug '13

Hi, I'm using a SQL database to store the usernames and passwords of my users. However, I have found that I must explicitly return the uid and gid with every query, even though all virtual users use the same uid and gid. The query, that works, is: user_query = SELECT mail, 'vmail' AS uid, 'vmail' AS gid, home, CONCAT('*:storage=', quota_MB*1024) AS quota_rule \ FROM virtual_users AS V LEFT JOIN virtual_domains AS D ON V.domain_id=D.id WHERE V.user='%n' AND D.name='%d' Nevertheless, if I remove the segments "'vmail' AS uid, 'vmail' AS gid" and modify the file conf.d/10-mail.conf to show mail_uid = vmail mail_gid = vmail I get this error: dovecot: auth: Error: userdb(<mail>): client doesn't have lookup permissions for this user: userdb reply doesn't contain uid (change userdb socket permissions) Does anybody know what is wrong in my set-up? Regards, Felix

Re: [Dovecot] dovecot Digest, Vol 124, Issue 4

Hello Axel, but then I don't get it: I thought that "uid" and "gid" in the user_query where used to access the local FS, whereas the "unix_listener auth-userdb" are used to indicate under which owner/group must be auth-userdb run... although maybe I'm wrong :-S :-) What I'm looking forward to is to eliminate the need for returning these two fixed items, as long as all the virtual_users will be using the same uid and gid. Does anybody know how can I do it?? Regards, and thank you!

[Dovecot] Wrong remote IP (rip) in mail.log using IMAP login
by tyli 02 Aug '13

02 Aug '13

Dear list users While trying to secure our dovecot server with fail2ban I came across the following problem: We use dovecot (1.2.9, ubuntu package) behind a NAT, and failed login attempts are logged with our firewall as the remote ip. Example: Apr 15 08:36:26 mail dovecot: imap-login: Disconnected (auth failed, 6 attempts): user=<xy>, method=PLAIN, rip=192.168.0.1, lip=192.168.0.3 Therefore I would ban 192.168.0.1 which means that I ban EVERY user. Funny thing is that POP3 login attempts are logged correctly: Apr 13 11:05:50 mail dovecot: pop3-login: Disconnected (auth failed, 1 attempts): user=<sgvyniwx>, method=PLAIN, rip=217.81.27.55, lip=192.168.0.3 Any ideas how to change this? Thanks in advance tyli

[Dovecot] trouble with setting individual quota values for multiple namespaces
by Andreas Oster 01 Aug '13

01 Aug '13

Hello all please apologize that I repost this problem again. I tried to get some help several times on the list but did not find/get a solution. I am still struggling to setup different quotas for namespaces. In addition to the default "INBOX" namespace I have created a namespace called "MailArchive" which should have its own quota value of 5G per user. At first I configured quota2 like this: quota2 = maildir:MailArchive quota:ns=MailArchive/ quota2_rule = *:storage=5G and this seemd to work quite well. Users, accessing the MailArchive namespace can see the 5G limit in their mail client, unfortunately in the mail.err log file, errors like these repeatedly appear: Jul 29 11:40:24 mailserver dovecot: imap(testuser): Error: quota: Unknown namespace: MailArchive/ Jul 29 11:41:43 dovecot: last message repeated 47 times In the WIKI I have read, that in order to have quota for different namespaces, one would have to use different quota backends so I changed the quota config for the MailArchive namespace to SQL. namespace inbox { disabled = no hidden = no ignore_on_failure = no inbox = yes list = yes location = mailbox Drafts { auto = subscribe driver = special_use = \Drafts } mailbox Junk { auto = subscribe driver = special_use = \Junk } mailbox Sent { auto = subscribe driver = special_use = \Sent } mailbox "Sent Messages" { auto = no driver = special_use = \Sent } mailbox Trash { auto = subscribe driver = special_use = \Trash } prefix = separator = / subscriptions = yes type = private } namespace { disabled = no hidden = no ignore_on_failure = no inbox = no list = yes location = maildir:/var/vmail/archive/%Ln/Maildir mailbox "Archived Mails" { auto = subscribe driver = } prefix = MailArchive/ separator = / subscriptions = yes type = private } plugin { quota = maildir:User quota:ns= quota2 = dict:Archive Quota:%u.mailarchive:ns=MailArchive/:proxy::sqlquota quota2_rule = *:storage=5G quota_rule = *:storage=1G quota_rule2 = Trash:storage=+200M } dict { sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } Unfortunately this did not change anything. Quota is working like expected but I still get the same errors in mail.err. I am currently using dovecot version 2.2.4. Thank you for your kind help best regards Andreas

[Dovecot] SSL warning messages

Hi, I've had the following appear in my logfile, and am just wondering what the warning means? dovecot: managesieve-login: Warning: SSL alert: where=0x4008, ret=256: warning close notify [a.b.c.d] dovecot: imap-login: Warning: SSL alert: where=0x4004, ret=256: warning close notify [w.x.y.z] Should I be worrying about these kinds of messages?

I think the cause is clear enough: you (user=md5i/uid=1000) are not part of group mail (gid=8), so the dovecot user process doing things on your behalf cannot create index files that are anlogous to the mailbox it's indexing. You can either 1) add "md5i" to group mail 2) remove g+w permission on your mail files (making group membership irrelevant) 3) fiddle with "mail_privileged_group = mail", but I'm a little hazy on all the ramifications of this. I don't know your particular circumstances, so I don't know which is best. If (big if) nothing on your system (particularly the MTA) requires access to your mail spool files by running as group=mail, probably 2) is your best option. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] LMTP: userdb lookup - user-filter with variables
by Burckhard Schmidt 31 Jul '13

31 Jul '13

I tried to use dovcots lmtp instead of dovecot-lda. postfix has in master.cf ... dovecot-lda -f ... -d ${user} to separate the user part from user(a)hostname.domain. So lookup of "user" succeeds in userdb (LDAP) done by dovecot-lda. I have always local addresses like to=<user(a)hostname.domain> postfix/lmtp[6579]: [ID 197553 mail.info] B3CDA66A16: to=<h0094slk(a)mailstore4.hu-berlin.de> With lmtp the userpart must be separated also. I tried user_filter (LDAP) with %n, %Ln, %8n without success: userdb lookup: user(a)hostname.domain doesn't exist) dovecot-2.1.17 I used "doveadm user h0094slk" and "doveadm user h0094slk(a)mailstore4.hu-berlin.de" for my tests. userdb { driver = ldap args = /usr/dovecot/etc/ldapuser.conf } and ldapuser.conf with ... user_filter = (&(uid=%n) (objectClass=cmsAccount)) user_attrs = homeDirectory=home I modified user_filter like uid=%Ln or uid=%8u success for doveadm user h0094slk (because nothing to split) userdb: h0094slk home : /home/p0094/h0094slk but no success for doveadm user h0094slk(a)mailstore4.hu-berlin.de userdb lookup: user h0094slk(a)mailstore4.hu-berlin.de doesn't exist It looks for me like user_filter do not use variables at this point?

"Hogging" CPU and memory is putting it strongly, as it is basically suspended while blocked on waiting for a connection, and if left for a long time in an idle state, might be swapped out to disk and not consuming (real) memory, or consuming real memory that isn't in use otherwise. As I stated before, the resource usage is small compared with all the other stuff going on, so if you don't have a busy mail server, I don't think you should sweat the difference. The benefits of LMTP should increase with load, as having LMTP resident will save you the overhead of repeatedly loading/unloading LDA, and I'm sure the CPU and memory usage of servicing that overhead will be non-trivial. If you have oodles of memory, then it's no problem keeping a LMTP resident. If you don't have enough memory and are VM disk thrashing, you'll have other problems and LDA/LMTP is the least of your worries. > And when it's running as root there is always the danger > of privilege escalation. LDA only runs when it's needed and since it > uses only user rights it shoudbe more harmless. I didn't contest the privilege separation aspect, as it a necessary design trade-off that one daemon doing things for all user will need overriding access. However, if this is a concern, you can virtualize all your users. LMTP can theoretically be subverted, but at least won't be as root. (I'm assuming LMTP stays as root, and not spawning off user processes to do the real work.) Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] LDA vs. LMTP
by Martin Burgraf 30 Jul '13

30 Jul '13

Hi there, I'm using Dovecot together with Postfix; as I understand it, there are two ways to transfer the mail from Postfix to Dovecot. 1.) by using LDA with mailbox_command = /usr/libexec/dovecot/dovecot-lda -f "$SENDER" -a "$RECIPIENT" 2.) by using LMTP with mailbox_transport = lmtp:unix:private/dovecot-lmtp (currently using number 1) I'm interessted in the differences and the advantages/disadvantages of each of those solutions. According to http://wiki2.dovecot.org/LDA the recommended way is to use LMTP, since it's supposed to have a better performance. On the other hand, http://wiki2.dovecot.org/LMTP says, that LMTP is a backgound process, while LDA is only called when needed. I've also read, that LDA only uses the users privileges, which both means, that LDA should be better. I've also noticed, that LMTP adds an additional Recieved:-Header to the mail. Are there any other differences? Thank you M.

[Dovecot] Maildir permissions and Solr re-indexing
by Michael Welsh Duggan 29 Jul '13

29 Jul '13

I am running a very small dovecot installation with only one user (me). I use the Solr indexer for indexing. Due to complicated reasons, I was forced to remove all the indexes and need to re-index everything. All the files in my Maildir are owned by md5i:mail (I am md5i), and have 660 permissions. All directories have the same user:group permissions, and 770 with the setguid bit set. (That last may not be necessary, but I was trying several things to get my use case to work.) Unfortunately, I can't seem to get re-indexing to work. When I do "doveadm fts rescan -A" as root, I get the following error for each of my subgroups: doveadm(md5i): Error: fchown(/home/md5i/Maildir/.mail.test/dovecot.index.log.newlock, group=8(mail)) failed: Operation not permitted (egid=1000(md5i), group based on /home/md5i/Maildir/.mail.test - see http://wiki2.dovecot.org/Errors/ChgrpNoPerm) After this, each directory has a dovecot.index.log with md5i:md5i 600 permissions. I've read the mentioned page, and played around with the ideas on it, but haven't gotten things to work. Anyone have any clue to ship my way? -- Michael Welsh Duggan (md5i(a)md5i.com)

[Dovecot] Upgrading to dovecot2 broke IDLE on one mailer, but not another
by John Stracke 29 Jul '13

29 Jul '13

Last weekend I upgraded my server (complete reinstall, actually), from Debian sarge to wheezy, which brought me from dovecot 1.x (I think) to 2.1.7. It's all working now, *except* that the MUA I use on Android, Kaiten (a fork of K-9), apparently no longer gets IDLE notifications. Before the upgrade, when mail arrived, Kaiten would pop up an Android notification immediately; now, it never does (or it might, hours later, with all the messages it notices at that time--presumably this happens when its background service gets killed off and restarted). The weird thing is that IDLE still works flawlessly with Thunderbird, which suggests this is a protocol interaction between Dovecot 2 and Kaiten. (I plan to check with the Kaiten folks next.) Has anybody here seen this? Is there something I can turn on in Dovecot to help debug it? I did check my old Dovecot settings, and they didn't specify anything non-default about IDLE. Thanks in advance!

[Dovecot] how to setup different quota for multiple namespaces
by Andreas Oster 29 Jul '13

29 Jul '13

Hello all, I am using dovecot for some time now but always had very basic configurations. I recently have configured a new, additional namespace in order to move archived mails (Thunderbird Archives) to another storage system. namespace { type = private separator = . prefix = Archives. location = maildir:/var/vmail/archive/%Ln/Maildir subscriptions = yes list = children inbox = no } This works well but unfortunately I cannot find a solution to either ignore this new namespace from quota computation or add a separate quota value for it. I have integrated user authentication with LDAP and fetch some user attributes from LDAP entries: user_attrs = =home=/var/vmail/%Ln/Maildir,=mail=maildir:/var/vmail/%Ln/Maildir/,otherPager=quota_rule=*:storage=%$ I configured the quota plugin in the following way: plugin { quota = maildir:User quota:ns= quota2 = maildir:Archive quota:ns=Archives. quota_rule = *:storage=1G quota_rule2 = ns=Archives.:ignore } unfortunately this does not give the desired result. Folders under the Archives namespace use the same quota as INBOX. Does anyone have an idea how to fix this ? Thank you for your kind help Andreas

[Dovecot] Case-insensitive "detail" mailboxes?
by /dev/rob0 27 Jul '13

27 Jul '13

We're using sieve with LMTP. We want to have lda_mailbox_autocreate and lmtp_save_to_detail_mailbox. Is there a way to make the "detail" case-insensitive? If so I have not found it yet. I suppose we could lowercase the input string for the SQL userdb query, but that's not what is wanted. The idea being that if a user makes a mailbox called "Test" is that user+test(a)example.com and user+TEST(a)example.com should both go to that "Test" mailbox. If it was lowercased, a mailbox called "Test" would be ignored and "test" used. With autocreate, this could be a problem if mail is delivered to autocreated case-sensitive mailboxes that the user won't see. Hmmm, maybe a global sieve script? -- http://rob0.nodns4.us/ -- system administration and consulting Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:

[Dovecot] dbus support in dovecot?
by Gene Heskett 27 Jul '13

27 Jul '13

Greetings; I am trying to transition from ubu10.04.4 LTS to ubu12.04.2 LTS, but in the changeover I want to setup dovecot as a local only imap server so that I can read & respond to email from any of the other 4 or so machines on my local net. To that end, and given that I have a well working setup right now, using fetchmail driving mailfilter as a pre-check, procmail as the MTA delivering to /var/spool/mail/me, with clamav and spamd in the mix to intercept and send to /dev/null the worst of the spam, or to a quarantine file if clamav triggers. The current transfer mechanism is driven by a script that uses inotifywait to detect newly delivered mail in that directory, and which then sends kmail a dbus message to go get the mail. Since I want to insert dovecot into this chain, does dovecot have a dbus port, and if so, what is the format of the command it expects? Thanks all.

[Dovecot] Namespace, Sieve and upgrading to dovecot 2.0 -- no folder "INBOX/"
by Ben 27 Jul '13

27 Jul '13

I just upgraded from debian squeeze->wheezy. This meant upgrading from dovecot 1.2 to 2.1.7 and upgrading to Pigdeonhole sieve. I have dovecot configured to use sieve and virtual users (I'll post config below) Now any message that come in get filtered by sieve, but any messages that don't hit any filters gives the error (in the sieve log): msgid=<XXXX(a)XXX.com>: failed to store into mailbox 'INBOX/': Invalid mailbox name As far as I can tell, Pidgeonhole has hard-coded to the behavior of 'keep' (that is unfiltered emails) to be: fileinto "INBOX/" However, in my setup "INBOX/" is not a valid folder. "INBOX" is. Is there a way to get pidgeonhole sieve to treat 'keep' as fileinto "INBOX"? Or do I need to reconfigure my dovecot namespaces? I tried playing with them, but everything works right now (sharing, etc) and when I changed my prefix on the inbox, etc, it did weird things (INBOX.INBOX.FOLDER) instead of (INBOX.Folder). Suggestions? Here is, I believe the relevant config info: dovecot.conf: namespace { inbox = yes location = prefix = separator = / type = private } namespace { list = children location = maildir:/Mail/Users/%%n/:INDEX=/Mail/Users/%u/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } Thanks, Ben

[Dovecot] dovecot-lda not logging if dovecot runs under daemontools
by Roberto Puzzanghera 26 Jul '13

26 Jul '13

Hello all, I have dovecot running under daemontools and I can't see dovecot-lda in action when I read the logs. I've set the logs to /dev/stderr because daemontools redirects /dev/stderr to /var/log/dovecot/current. The dovecot server works fine and I know that dovecot-lda is actually doing the delivery, because the sieve facility is working as well. I can get lda log working -but only on syslog- if I override the log_path in this way: protocol lda { mail_plugins = $mail_plugins sieve log_path = } I'm calling dovecot-lda in the usual qmail way. This is my .qmail-default: |/var/qmail/bin/preline -f /usr/libexec/dovecot/deliver -d $EXT@$USER As running dovecot under daemontools seems to be a common practice among qmail users, could any of you give me an hint on how dovecot should be configured to achieve the purpose? Thanks in advance.

[Dovecot] Managing IMAP IDLE/Push with Sieve – possible?
by FF 25 Jul '13

25 Jul '13

Hello, I've been using Dovecot with Sieve for a long time already, and I'm very happy with it. Push is working fine too. I was wondering, however, whether it would be possible to define a Sieve rule (perhaps using some plug-in), such that an IMAP push message gets sent out only for specific senders etc.? Have you come across anything like that? Thanks a lot, F.F.

[Dovecot] POP3 issues
by Thomas I Higgins 24 Jul '13

24 Jul '13

I have been trying off and on for the better part of a year to get a dovecot server migrated from one machine to another. It is currently working on CENTOS and we are trying to get it on Redhat. Currently I have everything migrated and working in IMAP, but we have one client device that requires POP3 (doesn't support IMAP). To this end, we have set up everything to work in POP3 as far as I can tell. In the dovecot.conf file, we show: protocols = imap imaps pop3 pop3s protocol pop3 { pop3_uidl_format = %08Xu%08Xv } The services running include: dovecot-auth imap-login imap-login imap-login pop3-login pop3-login pop3-login Everything else looks good including the logs which seem to show proper connectivity - messages are being received, accounts are connecting and disconnecting, etc. but the pop connections are not (apparently) passing messages found in that box. They are still just sitting there, not being read, picked up, or otherwise delivered by dovecot. Any ideas on what else I can check or change to get this to pick up? Thanks, Tom Higgins

I manually fixed it by copying src/plugins/zlib/lib20_zlib_plugin.la to /usr/local/lib/dovecot/doveadm I do not understand why 'make install' won't do that? A bug perhaps?

[Dovecot] OT: SAN vs Flash only SAN-less VM architecture for data storage
by Charles Marcus 21 Jul '13

21 Jul '13

Hello all, I am investigating options for leveraging our companies two locations, to provide fault tolerance/redundancy for our VM infrastructure. I was looking at SAN storage options, but ran across an interesting article, and would like opinions. It sounds great, a real win-win as to cost *and* performance... We have redundant/identical hosts at each location that can fulfill the requirements discussed... http://www.storage-switzerland.com/Articles/Entries/2012/9/20_The_Benefits_… or http://tinyurl.com/khwuspo Stan, I'm especially interested in your take, considering your experience with high end SANs and VM storage environments... Thanks, -- Best regards, Charles

[Dovecot] Archiving mail
by Koenraad Lelong 18 Jul '13

18 Jul '13

Hi, I'm going to migrate my company-mailserver to new hardware. I would like to take the opportunity to archive some older mail. But I would like to have it still accessible, would this be possible with dovecot ? I mean, I would like to put that older mail from different users (I got about 50 users) on some read-only media but mount that media in the users mail-dirs. That way I will have less to backup after I backup that old mail and store it safely away. I can't convince my users to really clean up their mailboxes, so I backup more than 100GB mail while the total backup is a bit more than 300GB. Writing this I realise I could give each user a folder oldmail and symlink that to a read-only oldmail folder. Would this work ? I will have to find out how my backup-software can ignore the oldmail-folder. Thanks for any suggestions, Koenraad Lelong

[Dovecot] Password encryption type for dovecot & postfix saslauthd with mysql
by Simon 18 Jul '13

18 Jul '13

Hi There, We are using dovecot v2.2.4 (compiled from source) and postfix (yum install) on Centos 6.4. We are storing our virtual user config in mysql. Server 1 has dovecot/postfix and accepts incoming mail from our mail filter servers - this is purely for IMAP/POP services. Server 2 has postfix for our clients to send email via TLS/saslauthd. Both use the same (separate) mysql server for config. One issue is that we have a requirement to merge user / passwords for sending clients from two sources: 1) the dovecot mailbox list 2). another list. The dovecot user list is email + password. The other list is username + password. To that end we have created a view table in mysql that merges the two.. tables + view look a little like this: table: mail_users (for dovecot) email,password test(a)test1.com,CRAM-MD5_PASSWORD test2(a)test1.com,CRAM-MD5_PASSWORD bla(a)bla.com,CRAM-MD5_PASSWORD table: mail_senders_other username,password username1,CRAM-MD5_PASSWORD something_else,CRAM-MD5_PASSWORD view: mail_senders (for postfix) username,password test(a)test1.com,CRAM-MD5_PASSWORD test2(a)test1.com,CRAM-MD5_PASSWORD bla(a)bla.com,CRAM-MD5_PASSWORD username1,CRAM-MD5_PASSWORD something_else,CRAM-MD5_PASSWORD I have dovecot working fine, but just need a little push in the correct direction (please) to figure out the correct settings and password encryption scheme to make the above work. Many thanks! Simon

[Dovecot] Dovecot 2.2.4 does not create home directory?
by Dmitry . 17 Jul '13

17 Jul '13

Hi, Does not create, or something I did wrong? Here http://wiki2.dovecot.org/VirtualUsers/Home it is written Home vs. mail directory Home directory shouldn't be the same as mail directory. It's possible to do that, but you might run into trouble with it sooner or later. Some problems with this are: and Ways to set up home directory The home directory is the same as the mail directory. If for example home=/var/vmail/domain/user/ mail=/var/vmail/domain/user/mail/, set: mail_home = /var/vmail/%d/%n mail_location = maildir:~/mail I think I've done it so. And yet, here http://wiki.dovecot.org/HowTo/SimpleVirtualInstall it is written Users can be added by editing this file. Dovecot automatically notices the new users immediately after they're added. It also creates their home directories when the user logs in. However, the directory is not created.

[Dovecot] Variable similar to %u but providing the username changed by a database lookup?
by Axel Luttgens 17 Jul '13

17 Jul '13

Hello, Variable %u may be used in dovecot.conf whenever the "full username" is needed. But the expansion of %u returns the username before a possible change performed thru a password or user database lookup (e.g., in the case of a SQL database, thru as "AS user" clause). Is there a variable that would expand to the changed name when used in the configuration file? TIA, Axel

[Dovecot] Fail2ban and logging
by Paul van der Vlis 17 Jul '13

17 Jul '13

Hello, Dovecot is logging authentication failures this way: ------ Jul 12 18:07:19 vps0 dovecot: imap-login: Disconnected (auth failed, 22 attempts in 172 secs): user=<info>, method=PLAIN, rip=82.95.148.152, lip=1.2.3.4, TLS, session=<QylMqlLhVwBSX5SY> ------ Fail2ban is trying to catch them with this regex: ------ failregex = .*(?:pop3-login|imap-login):.*(?:Authentication failure|Aborted login \(auth failed|Aborted login \(tried to use disabled|Disconnected \(auth failed).*rip=(?P<host>\S*),.* ------ This way fail2ban is counting 22 attempts as 1 attempt... I expect I need to change something on the logging, so that every attempt is seperate logged. But I don't know how. Is here somebody who knows how to get fail2ban correct working?

[Dovecot] courier to dovecot
by J Gao 17 Jul '13

17 Jul '13

Hi, All, I am new here and I need your advises. Here is my story: I have a mail server like this: - CentOS 5 32 bit (LAMP) - Postfix 2.3 - Courier - MailScanner Courier use maildir to save emails in /home/vmail/<virtual domain>/<user> / Now I want to build a new system on CentOS 6.4 64bit with postfix, dovecot and migrate all user accounts and their emails. I already installed CentOS 6.4, postfix and mysql. Also just installed Dovecot v2.2.4 from the RPM. Now I am looking into how to Is there a good instruction on how to do this kind of migration? I still prefer using the maildir system. If I just copy all users email from old server to new dovecot user maildir, will dovecot see these mails (and sub-folders) ? Do I need do anything extra? Thanks in advance. Gao -- __ _|==|_ ('')__/ >--(`^^') (`^'^'`) `======'

[Dovecot] reload without shutting imap connections down
by Hajo Locke 16 Jul '13

16 Jul '13

Hello, we have some problems with users who report connectionproblems to dovecot sometimes. According to the logs there are dovecot reloads at this times. Seems that a reload also causes dovecot to shut all imapconnections down: Jul 16 13:31:40 myhostname dovecot: master: Warning: SIGHUP received - reloading configuration Jul 16 13:31:40 myhostname dovecot: imap: Server shutting down. bytes=251/675 I tried to reload by initscript or sending -HUP manually to pid, dovecot is shutting down imapconnections and i think this is the reason for users to report this problems with some clients. This seems to be new with versions 2.x, i have some old 1.2.x dovecots running and cant find "Server shutting down" in their logs after reload. I have still potential to reduce reloads, but cant avoid them completely. Is there a workaround? Thanks, Hajo

[Dovecot] Difference between using auth_realms and setting up virtual mailboxes in postfix?
by Gab IIpop 16 Jul '13

16 Jul '13

Hi, there is a possibility in the future that I might have to support multiple domain names(but using the same IP address). Postfix has something called 'virtual mailboxes' to help handle this. But I also noticed that dovecot has a setting "auth_realms" where I can specify domains separated by a space. What is the relationship between the two?

[Dovecot] mail not reject when the mailbox is full (Dovecot-LDAP-Imap_quota)
by Victor Oñate 16 Jul '13

16 Jul '13

Hello List. Currently I have configured the share of users through the LDAP query as shown #dovecot.conf protocol imap { mail_plugins = quota imap_quota } plugin { quota = dirsize } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } #dovecot-ldap.conf auth_bind = yes ldap_version = 3 base = dc=XXX,dc=YY,dc=ZZ deref = never scope = subtree user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,mail=Maildir,mailQuotaSize=quota_rule=*:storage=%$ user_filter = (&(objectClass=posixAccount)(uid=%u)) pass_attrs = uid=user,userPassword=password,homeDirectory=userdb_home,uidNumber=userdb_uid,gidNumber=userdb_gid pass_filter = (&(objectClass=posixAccount)(uid=%u)) Additionally in thunderbird customers have the plug so they can see the share. This works perfect! However, when the mailbox exceeds 100% users continue to receive mail which makes the risk set allocated disk space, the idea is that when full the mail reject with a message "mailbox XXX full" . As always appreciate the ideas. Victor Oñate

[Dovecot] Proxying improvements in v2.1.2
by Timo Sirainen 16 Jul '13

16 Jul '13

I just committed a couple of features that will make life easier for some types of proxying setups: 1. IMAP proxying has already for a while supported sending local/remote IP/port to backend server, which can use it for logging and other purposes. I've now implemented this for POP3 as well, although only the remote IP/port is forwarded, not local IP/port. I implemented this also for LMTP in v2.2 tree, but haven't bothered to backport that change. Both POP3 and LMTP uses XCLIENT command that is compatible to Postfix's (XCLIENT ADDR=1.2.3.4 PORT=110). 2. proxy_maybe=yes + host=host.example.com actually works now. As long as host.example.com DNS lookup returns one IP that belongs to the current server the proxying is skipped. 3. auth_proxy_self = 1.2.3.4 setting means that if proxy_maybe=yes and host=1.2.3.4 then Dovecot assumes that this is a local login and won't proxy it, even if 1.2.3.4 isn't the actual local IP. This can be helpful if the host field contains load balancer's IP address instead of the server's. You can add more than one IP (space separated) and of course everything related to this works just as well with hostnames as with IPs (even when hostname expands to multiple IPs).

[Dovecot] Sieve vacation variables reference
by Simon 16 Jul '13

Hi There. We are using dovecot v2.2.4 with pigeonhole 0.4.1 (both compiled from source) Centos 6.4. Sorry for the dumb question in advance if I'm just missing an obvious link somewhere (also if I've got the terminology all wrong!), but could someone point me to the reference list for "vacation", e.g.: vacation :days :subject :addresses :from is there a definitive list of things like "days", "subject" etc? Thanks Simon

Hi There. We are using dovecot v2.2.4 with pigeonhole 0.4.1 (both compiled from source) Centos 6.4. We are storing our virtual user config in mysql. At the moment we are storing our sieve script configs in mysql and then running a script to write these out to a file.. But I'm wondering if there a way to store sieve scripts in mysql? Many thanks!

[Dovecot] Services not starting in 2.1 (or 2.2)
by Tommy Wareing 16 Jul '13

16 Jul '13

I'm trying to install Dovecot onto my QNAP NAS. I apologise for this! It means I'm not working in a normal environment, and don't (necessarily) have the normal range of tools available (or the most up to date version of those tools). It seems that 2.0.21 works (at least, as far as I've tested), but 2.1.17 and 2.2.4 won't start up their child services. I've got the source code for all three from http://www.dovecot.org/download.html, and, for experimental purposes, I'm configuring with: ./configure --prefix=/opt The configure script ends by reporting: Install prefix . : /opt File offsets ... : 64bit I/O polling .... : epoll I/O notifys .... : inotify SSL ............ : yes (OpenSSL) GSSAPI ......... : no passdbs ........ : static passwd passwd-file shadow checkpassword : -pam -bsdauth -sia -ldap -sql -vpopmail userdbs ........ : static prefetch passwd passwd-file checkpassword nss : -ldap -sql -vpopmail SQL drivers .... : : -pgsql -mysql -sqlite The dovecot.conf I'm using, at the moment, is the absolute minimal to fire things up: protocols = imap listen = * ssl_cert = </opt/etc/ssl/certs/dovecot.pem ssl_key = </opt/etc/ssl/private/dovecot.pem dovecot -n is happy, and reports those four lines back to me. When I start this up, I get, in /var/log/messages file: Jul 10 10:09:28 QNAP mail.info dovecot: master: Dovecot v2.0.21 starting up (core dumps disabled) and ps shows: [admin@qnap dovecot]# ps -ef | grep dovecot admin 11478 1 0 10:09 ? 00:00:00 /opt/sbin/dovecot dovecot 11479 11478 0 10:09 ? 00:00:00 dovecot/anvil admin 11480 11478 0 10:09 ? 00:00:00 dovecot/log admin 11482 11478 0 10:09 ? 00:00:00 dovecot/config admin 11525 455 0 10:10 pts/5 00:00:00 grep dovecot All is right with the world! Well, until I try to use dovecot properly, at which point I'll need a full configuration. But it's alright so far! :) However, if I go through the same routine with Dovecot 2.1.17, I get the appropriate message in messages: Jul 10 10:12:45 QNAP mail.info dovecot: master: Dovecot v2.1.17 starting up (core dumps disabled) But this time, ps shows: [admin@qnap dovecot-2.1.17]# ps -ef | grep dovecot admin 15259 1 0 10:12 ? 00:00:00 /opt/sbin/dovecot admin 15294 455 0 10:12 pts/5 00:00:00 grep dovecot and the child services don't seem to have started. This is born out by the fact that no network connections work: they stall, and then eventually time out (telnet localhost 143 produces no output at all, until I disconnect it). Even dovecot stop has trouble, taking several seconds before it returns me to the prompt, and *not* killing the existing process. dovecot -n is still happy however (and in a full configuration, components which don't require the services seem to work properly, such as dovecot-lda, if it doesn't require auth). I'm not sure that I need those newer versions of dovecot, so I'll get back to version 2.0 for now. But I'd certainly like the option, and imagine that somebody else might care as to what the problem is! -- Tommy Wareing

[Dovecot] trying to configre dovecot
by Gene Heskett 15 Jul '13

15 Jul '13

Hi all; Thinking I'd like to have a bit of security, I followed the example for dovecot from allgoodthings.org Guessing between the lines I made a few substitutions to localize it for me, but when I run the line to dump the configs, the output is very short because I do not have the *.pem files. Where can a usable set of these ssl 'keyfiles' be obtained? Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

[Dovecot] User login for SMTP but not for IMAP/POP?
by Martin 15 Jul '13

15 Jul '13

Hello everybody, I have a question, though I'm not sure if it's a matter of dovecot or postfix. Or if it's even possible to do at all. If I understand it correctly, SMTP authentification is done via SASL. When a user wants to login Postfix queries an external user database (dovecot). Therefore the SMTP-users are identical to the IMAP/POP-users. I want to achieve the following: I want some user credentials (username&password) for a user that is able to login via SMTP, but who doesn't have a mailbox and therefore shouldn't be able to login via IMAP/POP. Is this even possible? How can it be achieved? Or: does this behaviour have a special name, which I can google for? Regards, Martin

[Dovecot] login_trusted_networks from webmail ?
by Jan-Frode Myklebust 15 Jul '13

15 Jul '13

I'd like to get the IP-address of the webmail-klient logged in my maillog (for being compliant with coming data retention policies). I've noticed that with login_trusted_networks pointing at my dovecot directors, we get rip=client-ip logged on the backends. How is the proxy providing this to the dovecot backends? Anybody know what magic we need to implement in our webmail-solution to be able to forward the webmail-client-ip and have it logged as rip= in dovecot? I belive it will be enough to have it logged as rip= on the directors, maybe not needed to be forwarded all the way to the backends (but that would be nice as well). -jf

[Dovecot] new user questions
by Gene Heskett 14 Jul '13

14 Jul '13

Greetings; Trying to follow along with the wiki2 setup instructions and thought I'd hit a snag with the first "send me a mail" snippet as it took several minutes to arrive, so I assume that somehow procmail was involved in the delivery and my procmail runs mail thought a whole bunch of checks before finally handing it off to a mailfile as /var/mail/gene. Then the next script seems to only try whats in my home dir, and of course doesn't find it as neither exists, yet... I assume that is because dovecot needs a kill -HUP. But I am not familiar with that, so how is it done, and as what user, me, or root, on a ubuntu 12.04.2 LTS install? Thanks.

[Dovecot] Mail replication ... totally confused !
by HL 13 Jul '13

13 Jul '13

Hello, I am totally confused configuring replication in dovecot. In my case I have 2 servers instead of running rsync as a daemon which takes a lot of time I would like SERVER-A will be the master and SERVER-B will be the slave My users directly interact with server A, Server B stands as a mails backup only I've setup SERVER-B ( backup ) like that, NO SPECIAL CONF on master SERVER-A Is this ok ?? I Don't want to miss any mails Since this is a live server service aggregator { # give enough permissions for mail processes # fifo_listener replication-notify-fifo { user = vmail mode = 0600 } unix_listener replication-notify { user = vmail mode = 0600 } } service replicator { # start replication at startup # process_min_avail = 1 } service doveadm { # if you're using a single virtual user, set this to start ssh as vmail # (not root) # user = vmail } service config { # needed to grant access to /var/run/dovecot/config for service doveadm # unix_listener config { user = vmail } } dsync_remote_cmd = ssh -p 1234 -l%{login} %{host} doveadm dsync-server -u%u -l%{lock_timeout} -n%{namespace} plugin { mail_replica = remote:vmail@master-server-a.tld replication_full_sync_interval = 1 hours }

[Dovecot] Ambiguous behavior with prefetch database?
by Axel Luttgens 13 Jul '13

13 Jul '13

Hello, Let's say dovecot.conf contains: mail_uid = dovemailer mail_gid = dovemailer mail_home = /some/path/%n mail_location = mbox:~/mboxes:INBOX=~/mboxes/inbox and that the password database query is of the form: password_query = \ SELECT \ passwd AS password, \ nickname AS user, \ mail_home AS userdb_home, \ mail_location AS userdb_mail, \ WHERE \ ... The database initially comes with NULL for both mail_home and mail_location, the goal being to be able to progressively replace legacy settings. With the above, one gets such entries in the logs upon a pop or imap connection: auth-worker(11262): Debug: auth(u12345678,127.0.0.1): username changed u12345678 -> john.doe auth: Debug: auth(u12345678,127.0.0.1,<dsNsasbgRQB/AAAB>): username changed u12345678 -> john.doe [...] auth: Debug: prefetch(john.doe,127.0.0.1,<dsNsasbgRQB/AAAB>): passdb didn't return userdb entries, trying the next userdb and, of course, the userdb_query fails since it isn't supposed to be invoked under such circumstances. Of course, the userdb_query could be adapted so as to handle pop/imap connections in addition to say, lmtp or doveadm connections, but this would anyway raise the question: why bother with a prefetch database setup? In fact, it seems that the problem comes from the fact that the password_query returns NULL values (i.e. "do not override dovecot.conf settings") for all userdb_xxx settings even if, technically speaking, it returns such columns. A slight yet somewhat silly modification of the password_query, such as this one: password_query = \ SELECT \ passwd AS password, \ nickname AS user, \ 'dovemailer' AS userdb_uid, \ mail_home AS userdb_home, \ mail_location AS userdb_mail, \ WHERE \ ... indeed seems to bring back all the expected behavior: now, the "passdb returns userdb entries" and, for example, the config's mail_home expands to the expected value /some/path/john.doe. Could it be that the case "userdb_xxx columns returned, even if all with NULL values" has been somehow overlooked in the code? Or am I erring with my interpetation of all those matters? TIA, Axel

[Dovecot] A sqlite-based quota dict
by Axel Luttgens 13 Jul '13

13 Jul '13

Hello, While experimenting with the sqlite backend, I noticed a big vacuum wrt its use for a quota dict. This is thus an opportunity to share a solution I managed to devise after some trials and errors and a (very quick and unscientific) look at the code. And also the opportunity to ask the community to check for possible flaws. Yes, nothing comes for free... ;-) TIA, Axel This is the SQL for creating the database or for adding needed table/trigger to an existing database (with many comments and few "active" lines): CREATE TABLE quota ( -- We will assume that, in the case of a sqlite DB (and probably a pgsql DB -- as well), Dovecot will *always* act along these lines: -- In case of a "row creation": -- INSERT INTO quota (subject, byte_count) -- VALUES (<some id>, <byte count>); -- INSERT INTO quota (subject, message_count) -- VALUES (<some id>, <msg count>); -- In case of a recalculation: -- UPDATE quota -- SET byte_count = byte_count + <byte count diff>, -- message_count = message_count + <msg count diff> -- WHERE subject = <some id>; -- In case of a row deletion: -- DELETE FROM quota -- WHERE subject = <some id>; -- For example, a "doveadm quota recalc" may first delete the relevant row -- if it exists, then (re-)create it. -- Clearly, the "row creation" case is a bit problematic, hence the need for -- a trigger. -- An id for the entity subjected to a quota (a user/mailbox, a domain...). subject TEXT PRIMARY KEY NOT NULL, -- The entity's size, expressed as a storage space use and as a message -- count. -- Note the NULL defaults: they allow to simplify the trigger's logics. byte_count INTEGER DEFAULT NULL, message_count INTEGER DEFAULT NULL ); CREATE TRIGGER quota_insert BEFORE INSERT ON quota FOR EACH ROW BEGIN -- If there's a row to update, that's because the first INSERT of the "row -- creation" has been performed. -- (this UPDATE could probably be simplified if the insertion order, -- byte_count then message_count, was guaranteed; anyway, since the "row -- creation" operation shouldn't be very frequent, we may afford a slight -- inefficiency). UPDATE quota SET byte_count = CASE WHEN NEW.byte_count ISNULL THEN byte_count ELSE NEW.byte_count END, message_count = CASE WHEN NEW.message_count ISNULL THEN message_count ELSE NEW.message_count END WHERE subject = NEW.subject; -- In which case we may ignore that second (current) INSERT, since the -- previously inserted row has just been updated with the value coming -- from the current INSERT statement. SELECT raise(IGNORE) WHERE EXISTS (SELECT * FROM quota WHERE subject = NEW.subject); END; The corresponding dict configuration being thus supposed to be similar to this one: connect = /path/to/database map { pattern = priv/quota/storage table = quota username_field = subject value_field = byte_count } map { pattern = priv/quota/messages table = quota username_field = subject value_field = message_count }

[Dovecot] Dovecot Virtual Folders... could these be managed by a/the Client?
by Charles Marcus 12 Jul '13

12 Jul '13

Hi all/Timo, I was thinking about Thunderbirds ability to create Virtual folders allowing you to have many different views of your messages... The downside though, is you only see these in Thunderbird. I know that dovecot supports server side virtual folders: http://wiki2.dovecot.org/Plugins/Virtual But I'm wondering about the possibility to manage these from the client side... For example, would it be possible to create an extension in Thunderbird that allowed the user to manage these (create, edit the filters for, delete, rename, etc)? Thanks, -- Best regards, Charles

[Dovecot] (no subject)
by Gab IIpop 12 Jul '13

12 Jul '13

>From the documentation, virtual users seem like a good idea if you plan on having a lot of users. Although I'm wondering about the following: What other benefits/consequences are there to using virtual over system users and vice versa? Will virtual users have the same protection as system users (system users would use linux permissions, which is pretty secure)? How easy will it be to switch from using system users to virtual users or vice versa?

12 Jul '13

Hello, I'm using a nagios check to monitor dovecot status, since dovecot v2 I see those syslog messages on every nagios check: pop3-login: Aborted login (no auth attempts in 0 secs) imap-login: Aborted login (no auth attempts in 0 secs) I tried to avoid those messages sending a logout string: check_imap -H localhost -e 'OK' -s 'a logout' check_pop -H localhost -e 'OK' -s 'quit' but now I get imap-login: Disconnected (no auth attempts in 0 secs) pop3-login: Disconnected (no auth attempts in 0 secs) what can I do to avoid a log message on every nagios check? thanks! Lluís

[Dovecot] getting quota error when accessing private namespace
by Andreas Oster 12 Jul '13

12 Jul '13

Hi all, I have run into a problem which I cannot find a solution for. I have created an additional private namespace with the following commands in dovecot.conf : namespace { disabled = no hidden = no ignore_on_failure = no inbox = no list = children location = maildir:/var/vmail/archives/%Ln/Maildir mailbox "archived mails" { auto = subscribe driver = special_use = \Archive } prefix = Archives/ separator = / subscriptions = yes type = private } plugin { quota = maildir:User quota:ns= quota2 = maildir:Archives quota:ns=Archives/ quota2_rule = *:storage=5G quota_rule = *:storage=1G quota_rule2 = Trash:storage=+200M } I can access the new namespace without any problems but every time a folder in this namespace is accessed, I get the following error messages in mail.err log: dovecot: imap(testuser): Error: quota: Unknown namespace: Archives/ dovecot: last message repeated 49 times Quota seems to work, though I have the feeling, that it only will be updated when closing and reopening the mail client, but this can also be a client issue. Quota for the INBOX is either taken from LDAP or, if there is no value defined in LDAP, will be assigned a quota of 1G The Archives/ namespace has a static quota of 5G for every user. Does anyone have idea how to get rid of these error messages ? Thank you for your kind help Andreas

[Dovecot] Multiple Folders Continually Auto-Created
by Cassidy Larson 12 Jul '13

12 Jul '13

I've had reports of a number of clients running Outlook 2011 on Mac where they have quite a few folders with the same name appended by multiple "1"s. So far I've only narrowed it down to Outlook 2011 on Mac. We've been in the process of migrating to sdbox on a new server from maildir using dsync backup. Example folder structure: INBOX INBOX 1 INBOX 1 1 INBOX 1 1 1 INBOX 1 1 1 1 INBOX 1 1 1 1 1 INBOX 1 1 1 1 1 1 INBOX 1 1 1 1 1 1 1 INBOX 1 1 1 1 1 1 1 1 INBOX 1 1 1 1 1 1 1 1 1 INBOX 1 1 1 1 1 1 1 1 1 1 Junk Junk 1 Junk 1 1 Junk 1 1 1 Junk 1 1 1 1 Junk 1 1 1 1 1 Junk 1 1 1 1 1 1 Junk 1 1 1 1 1 1 1 Junk 1 1 1 1 1 1 1 1 and so on for "Sent Messages", etc. Seems that the the default folders for these clients are getting created over and over again, each time with a new "1" at the end. Anybody else see this? I'm digging for a client I can troubleshoot with and reproduce with me watching. Thanks, -c

[Dovecot] SSL cert problem
by Peter von Nostrand 12 Jul '13

12 Jul '13

Hi, I'm running a new dovecot 2.0.9 under Centos 6.4. I'm having an issue with SSL certificate not being accepted by the email client. I have my own CA and I have generated certificates for web usage without a problem. For imaps and pop3s what I did was generate a certificate for the hostname of my dovecot server and then cat that cert with the intermediate and root CA certificates. No matter what thunderbird still complains with Unknown identity. # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-358.2.1.el6.x86_64 x86_64 CentOS release 6.4 (Final) auth_mechanisms = plain login auth_socket_path = /var/run/dovecot/auth-userdb auth_username_format = %n disable_plaintext_auth = no log_path = /var/log/dovecot.log mail_fsync = never mail_home = /vmail/%u 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 mbox_write_locks = fcntl 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 pop3 lmtp sieve quota_full_tempfail = yes service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail mode = 0660 user = vmail } } service lmtp { unix_listener lmtp { user = vmail } } service managesieve-login { inet_listener sieve { port = 4190 } } service pop3-login { inet_listener pop3s { port = 995 ssl = yes } } ssl_cert = </etc/pki/dovecot/certs/mail.pem ssl_key = </etc/pki/dovecot/private/mail.example.com.key userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } verbose_ssl = yes protocol lmtp { mail_fsync = optimized mail_plugins = sieve quota } protocol lda { mail_plugins = sieve quota } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota This is the log: Jul 11 15:38:45 imap-login: Warning: SSL: where=0x10, ret=1: before/accept initialization [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2001, ret=1: before/accept initialization [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2002, ret=-1: SSLv2/v3 read client hello A [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 read client hello A [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 write server hello A [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 write certificate A [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 write key exchange A [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 write server done A [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 flush data [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2002, ret=-1: SSLv3 read client certificate A [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2002, ret=-1: SSLv3 read client certificate A [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 read client key exchange A [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 read finished A [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 write session ticket A [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 write change cipher spec A [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 write finished A [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 flush data [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x20, ret=1: SSL negotiation finished successfully [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2002, ret=1: SSL negotiation finished successfully [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL alert: where=0x4004, ret=558: fatal certificate unknown [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL alert: where=0x4008, ret=256: warning close notify [192.168.0.1] Jul 11 15:38:45 imap-login: Info: Disconnected (no auth attempts): rip=192.168.0.1, lip=192.168.1.1, TLS: SSL_read() failed: error:14094416:SSL routines:SSL3_READ_BYTES:sslv3 alert certificate unknown: SSL alert number 46 Thx in advance -- Peter

[Dovecot] dsync/imapc migration question
by Gedalya 12 Jul '13

12 Jul '13

Doing an imapc migration with the pop3 migration plugin, using doveadm backup -R. I occasionally get the following output: dsync(user(a)domain.tld): Error: imapc(mail01.domain.tld:143): Server disconnected unexpectedly dsync(user(a)domain.tld): Error: imapc(mail01.domain.tld:143): Server disconnected unexpectedly dsync(user(a)domain.tld): Error: imapc(mail01.domain.tld:143): Server disconnected unexpectedly dsync(user(a)domain.tld): Warning: I/O leak: 0xb7648650 (line 1229, fd 10) dsync(user(a)domain.tld): Warning: I/O leak: 0xb7648650 (line 1229, fd 11) dsync(user(a)domain.tld): Warning: Timeout leak: 0xb76488b0 (line 1316) dsync(user(a)domain.tld): Warning: Timeout leak: 0xb76488b0 (line 1316) The source server is really crappy, no need to look at the dovecot side for causes. My question is: is it possible that the migration did complete successfully? Dovecot does seem to continue and it's kind of vague on what went wrong, and did it re-try. This operation can take several hours on large mailboxes so this question is really meaningful in my case. (I'd try with -D but it's really hard to reproduce this on demand). Thanks Gedalya

[Dovecot] Pigeonhole vacation auto-response not respecting "days" parameter
by Thomas Harold 11 Jul '13

11 Jul '13

This might be a PEBKAC on my end, but in our old server, "vacation" responses would only be sent back to an origin address once per day because we had ":days 1" in the rule. On the new server, even though we have ":days 1", pigeonhole is sending responses to every message, resulting in multiple vacation responses each day back to each origin address. The following was generated by Roundcube's web interface, it looks to be correct. ----------------------- require ["vacation"]; # rule:[vacation-reply] if allof (not header :contains "Subject" "[spam]", not exists "List-Unsubscribe") { vacation :days 1 :addresses ["email1(a)example.com","email2(a)example.com"] :subject "Out of office reply" text: I am currently out of the office July 11th and 12th, returning on July 15th. During this time I will have no access to email. Thank you. User So-And-So . ; } ----------------------- Interestingly, if I look at .dovecot.sieve.log, I see error messages like (except that the vacation responses are, in reality, being sent): error: msgid=<20130711134816.35B9A40335(a)mail.example.com>: failed to send vacation response to <originemail(a)example.com> (refer to server log for more information). And in the maillog: Jul 11 09:48:17 servername sendmail[28244]: r6BDmHem028244: SYSERR(UID1132): Who are you? Jul 11 09:48:17 servername sendmail[28244]: r6BDmHem028244: Authentication-Warning: servername .example.com: Unknown UID 1132 set sender to <> using -f Jul 11 09:48:17 servername sendmail[28244]: r6BDmHem028244: from=<>, size=725, class=-60, nrcpts=1, msgid=<dovecot-sieve-1373550497-202242-0(a)servername.example.com>, relay=Unknown UID 1132@localhost My guess at this point is that I've failed to configure pigeonhole and/or postfix's copy of the sendmail command properly so that it can create the "who I have send mail to recently" file.

[Dovecot] How to manipulate attachments with LDA?

Hi All, I want to plug in a tool that will convert attachments somewhere into a mail delivery process (postfix->dovecot). I think deliver would be a good place to do it. Does it make sense? Could you direct me where I could read about how to do it please? Piotr Szafarczyk

[Dovecot] Have an issue with catch-all - Dovecot-lda andPostfix
by Joakim Ohlsson 10 Jul '13

10 Jul '13

Hi, I run dovecot version 2.1.7 and postfix 2.9.6. I'm using dovecot-lda as local delivery. I use virtual users and need to use catch-all for some of my domains. My problem when using catch-all is that I got a separate email for each recipient. As an example: If I send mail to: test1(a)test.org, test2, test3(a)test.org, test4(a)test.org and have a catch-all which will send this mail to test(a)test.org. In this example I get 4 mails in my test(a)test.org inbox and in TO: field in the header I have all this four recipients: TO: test1(a)test.org, test2, test3(a)test.org, test4(a)test.org. In my dovecot log: 2013-07-10 13:49:25 lda(test(a)test.org): Debug: Destination address: test(a)test.org (source: user@hostname) 2013-07-10 13:49:25 lda(test(a)test.org: Info: msgid=<20130710114924.DBA3F9FA8D(a)mail2.test.org>: saved mail to INBOX 2013-07-10 13:49:25 lda(test(a)test.org): Info: msgid=<20130710114924.DBA3F9FA8D(a)mail2.test.org>: saved mail to INBOX 2013-07-10 13:49:25 lda(test(a)test.org): Info: msgid=<20130710114924.DBA3F9FA8D(a)mail2.test.org>: saved mail to INBOX 2013-07-10 13:49:25 lda(test(a)test.org): Info: msgid=<20130710114924.DBA3F9FA8D(a)mail2.test.org>: saved mail to INBOX My question is if it's possible to receive just one mail instead of four? If I send the mail via Spamassassin I'll just receive one mail to test(a)test.org with TO: test1(a)test.org, test2, test3(a)test.org, test4(a)test.org in the header. Thanks in advance Br Joakim # dovecot -n:

[Dovecot] Dovecot SLOW in imaptest without any apparent reason
by FABIO FERRARI 10 Jul '13

10 Jul '13

Hello, I'm migrating a mail server from a centos 5 cluster architecture to a centos 6 cluster architecture. The new cluster involves faster machines then the old cluster, and a virtual machine. I use dovecot-2.0.9-5.el6.x86_64, while the old cluster uses dovecot-2.0.1-1_118.el5. Tha mail server uses mysql for the users database, and a local ldap for authentication. The storage is also much faster in the new cluster: OLD SERVER: date; dd if=/dev/zero of=/cl/prova.bin bs=102400 count=10240; sync; date Wed Jun 26 15:43:53 CEST 2013 10240+0 records in 10240+0 records out 1048576000 bytes (1.0 GB) copied, 30.0202 seconds, 34.9 MB/s Wed Jun 26 15:44:28 CEST 2013 --> 1GB / 35 secs = about 29.25 MB/sec NEW SERVER: date; dd if=/dev/zero of=/cl/prova.bin bs=102400 count=102400; sync; date mar 25 giu 2013, 15.46.36, CEST 102400+0 records in 102400+0 records out 10485760000 bytes (10 GB) copied, 62,5143 s, 168 MB/s mar 25 giu 2013, 15.48.33, CEST [root@eta ~]# ---> 10GB / 117secs = about 85.47MB/sec An 'ls -l' in the user direcotry is also much faster, when the ldap/sssd cache is populated: OLD SERVER: real 0m8.540s user 0m1.229s sys 0m0.699s NEW SERER: real 0m3.938s user 0m0.250s sys 0m0.151s But my imaptest is much slower: ./imaptest user=XXXXXXX pass=XXXXXXX secs=120 seed=123 mbox=./dovecot-crlf OLD SERVER: Totals: Logi List Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo 100% 50% 50% 100% 100% 100% 50% 100% 100% 100% 100% 30% 5% 1122 559 547 1121 1121 1568 136 900 1121 1121 2244 NEW SERVER Totals: Logi List Stat Sele Fetc Fet2 Stor Dele Expu Appe Logo 100% 50% 50% 100% 100% 100% 50% 100% 100% 100% 100% 30% 5% 390 210 185 389 389 589 49 320 389 389 780 The configuration is exactly the same in the 2 clusters, that is: ----------- # 2.0.1: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-348.3.1.el5 x86_64 Red Hat Enterprise Linux Server release 5.9 (Tikanga) xfs auth_cache_size = 1024 auth_cache_ttl = 21600 s auth_debug = yes auth_debug_passwords = yes auth_master_user_separator = * auth_mechanisms = plain login auth_socket_path = /var/run/dovecot/auth-userdb auth_verbose = yes base_dir = /var/run/dovecot/ disable_plaintext_auth = no hostname = mail.unimore.it info_log_path = /var/log/dovecot.log lda_mailbox_autocreate = yes log_path = /var/log/dovecot.log mail_debug = yes mail_location = maildir:/cl/mail/vhosts/sms.unimo.it/%Ln/Maildir mail_plugins = $mail_plugins quota mailbox_idle_check_interval = 60 s mbox_write_locks = fcntl namespace { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = /usr/local/etc/dovecot.masterusers driver = passwd-file master = yes } passdb { args = dovecot driver = pam } plugin { quota = maildir:User quota quota_exceeded_message = Quota exceeded (mailbox is full) quota_rule = *:storage=200MB quota_rule2 = *:messages=100000 quota_rule3 = INBOX.Trash:storage=+100M quota_warning = storage=90%% quota-warning 90 %u quota_warning2 = storage=85%% quota-warning 85 %u quota_warning3 = messages=95%% quota-warning 95 %u quota_warning4 = messages=80%% quota-warning 80 %u setting_name = quota } postmaster_address = postmaster(a)unimore.it quota_full_tempfail = yes service anvil { client_limit = 199999 process_limit = 1 } service auth { client_limit = 21224 unix_listener auth-userdb { mode = 0600 user = vmail } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 } process_limit = 10000 } service imap { process_limit = 10000 } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 } } service pop3 { process_limit = 1024 } service quota-warning { executable = script /usr/local/bin/quota-warning.sh unix_listener quota-warning { group = vmail user = vmail } user = dovecot } ssl_ca = </etc/pki/tls/certs/ca_unimore_tcs.pem ssl_cert = </etc/pki/tls/certs/mailposta1.pem ssl_key = </etc/pki/tls/certs/mailposta1.key userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } verbose_ssl = yes protocol lda { mail_plugins = $mail_plugins quota } protocol imap { mail_plugins = $mail_plugins } protocol pop3 { mail_plugins = $mail_plugins quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } ----------- Is anyone able to tell me what I have to check? thanks in advance Fabio Ferrari

[Dovecot] Strange Problems when deleting folders.
by Davide Bozzelli 10 Jul '13

10 Jul '13

Hi I'm experiencing a strange problem on my dovecot 2.0.21 setup. When i delete a folder "foo" it was correctly moved in the trash folder. If i try to delete from it the folder "foo" from the trash it gets renamed "foo1". If I try to dlete "foo1" it gets renamed foo11, and the operation could be continued figured out in an endless loop. This happens both from thunderbird and sogo (a webmail). Is it a known bug or a misconfiguration ? Thx in advance

[Dovecot] Migrating domain using IMAPc

Hi list, I'm trying to do a domain migration using the imapc feature, but i'm having some problems and I really don't know what is happening. So if you guys could help me with a path to solve this, I will be glad. I'm using Dovecot 2.1.7 in a Debian Wheezy machine.

[Dovecot] LMTP Proxy
by Cassidy Larson 10 Jul '13

10 Jul '13

Trying to figure out Proxying with LMTP to a few back end storage servers for quota checking before accepting email delivery on the front end nodes. If I connect to the back end server directly via telnet, everything works great. If I use a front-end server to proxy to the back end server, I don't get the same result. Running 2.2.4 on both front and back end servers. Any help would be appreciated. ------ backend dovecot.log: dovecot: lmtp(72274): Error: userdb lookup(user@host*masteruser): Disconnected unexpectedly dovecot: auth: Fatal: master: service(auth): child 72272 killed with signal 11 (core not dumped) ------ front end dovecot.log: dovecot: lmtp(7495): Debug: auth input: user=user(a)host.comnopassword=<hidden> host=<backend_server_ip> destuser= user(a)host.com*masteruser nologin=Y nodelay=Y proxy=Y pass=<hidden> port=2525 ------ front end dovecot.conf: lmtp_proxy = yes protocols = lmtp protocol lmtp { postmaster_address = postmaster(a)mydomain.com mail_plugins = quota passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf driver = sql } } service lmtp { client_limit = 5 executable = lmtp idle_kill = 0 process_limit = 0 process_min_avail = 0 protocol = lmtp service_count = 0 inet_listener lmtp { address = <frontend_server_ip> port = 2525 } } ------ backend dovecot.conf: auth_master_user_separator = * lmtp_rcpt_check_quota = yes passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf driver = sql master = yes } userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf driver = sql } service lmtp { client_limit = 5 executable = lmtp -L idle_kill = 0 process_limit = 0 process_min_avail = 0 protocol = lmtp service_count = 0 inet_listener lmtp { address = <backend_server_ip> port = 2525 } } protocol lmtp { info_log_path = /var/log/dovecot-lmtp.log postmaster_address = postmaster(a)infowest.com mail_plugins = quota }

[Dovecot] Non-blocking file_dotlock_open() in quota-maildir question
by do1＠yandex.ru 10 Jul '13

10 Jul '13

Hello, Is it safe to change lines in plugins/quota/quota-maildir.c::maildirsize_write() from fd = file_dotlock_open_group(.., DOTLOCK_CREATE_FLAG_NONBLOCK, ..); to fd = file_dotlock_open_group(.., 0, ..); ? Rationale is: exim+cpanel frequently leave stale maldirsize.lock, but when quota plugin try to dotlock maildirsize, it do this with NONBLOCK flag and just once, so first lock fails with EAGAIN and second may never happen. (When last mail is over quota this also prevent user from further receiving any mail because quota remain exceeded, forver. This is annoing problem.) I wonder if it is possible to do easy fix problem by removing NONBLOCK flag, but as I don't understand why this NONBLOCK flag is used in the first place I decided to ask developers in the list for approval. If removing NONBLOCK flag is not possible I will just call file_dotlock_open_group() twice if first one return -1 with EAGAIN. Best regards, Don.

[Dovecot] Mailbox statistics (sdbox / indexes) (+ wiki2 frontpage notes)
by Jeroen Massar 10 Jul '13

10 Jul '13

Hi, I used to, with a simple script, loop over the filenames in a Maildir, grab the From from the contents of the file and grab the flags (especially "READ" and "REPLIED") from the filename, but after moving to sdbox these flags are hidden in the index file. Is there anyway to get these out of there programmatically without having to resort to using an imap-client or is that the way to go? (I am effectively counting who has sent the most mail to a mailbox and how many of the the messages have been and have not been replied to; thus another answer would be: "I got a stats program for mailboxes") Greets, Jeroen PS: just reverted the wiki2 Frontpage, apparently even bots know who the author of the IMAP protocol is (leading me to believe that that check does not work): http://wiki2.dovecot.org/FrontPage?action=info I could not find a "revert" button thus copied&pasta'd the previous edition in there. PS2: there seems to be a master.wiki2.dovecot.org and a wiki2.dovecot.org; logging in on the one does not log in on the other, and accounts on the one are different from the other, and it seems cookies go missing also somewhere, hence why an IP is logged and not my account (which I used to have, now was missing and thus I recreated, but needed to do that on both boxes)

[Dovecot] [PATCH] login-common: Add support for ECDH/ECDHE cipher suites
by David Hicks 10 Jul '13

10 Jul '13

# HG changeset patch # User David Hicks <david(a)hicks.id.au> # Date 1373085976 -36000 # Sat Jul 06 14:46:16 2013 +1000 # Node ID ccd83f38e4b484ae18f69ea08631eefcaf6a4a4e # Parent 1fbac590b9d4dc05d81247515477bfe6192c262c login-common: Add support for ECDH/ECDHE cipher suites ECDH temporary key parameter selection must be performed during OpenSSL context initialisation before ECDH and ECDHE cipher suites can be used. OpenSSL >= 1.0.2 automatically handles ECDH temporary key parameter selection. For OpenSSL < 1.0.2 we must manually specify a named elliptic curve that Dovecot will use to generate an ephemeral key pair. By default we try to use the same named curve as that used in the server's private EC key file. If this attempt fails, a fall back curve of NIST P-384 (secp384r1) is used instead. RFC 6460 states that NIST P-384 MUST be used for cipher suites that include AES-256. For cipher suites that include AES-128, RFC 6460 states that NIST P-256 MUST be used. No matter which curve is used as a fall back option, Dovecot will be non-compliant. The reason for selecting NIST P-384 as a fall back curve is to ensure that the non-compliance is in the form of providing too great a level of security for AES-128 cipher suites rather than too little security for AES-256 cipher suites. diff -r 1fbac590b9d4 -r ccd83f38e4b4 src/login-common/ssl-proxy-openssl.c --- a/src/login-common/ssl-proxy-openssl.c Fri Jun 28 19:48:37 2013 +0300 +++ b/src/login-common/ssl-proxy-openssl.c Sat Jul 06 14:46:16 2013 +1000 @@ -119,6 +119,10 @@ const struct master_service_ssl_settings *ssl_set); static void ssl_server_context_deinit(struct ssl_server_context **_ctx); +static void ssl_proxy_ctx_set_crypto_params(SSL_CTX *ssl_ctx, + const struct master_service_ssl_settings *set); +static int ssl_proxy_ctx_get_pkey_ec_curve_name(const struct master_service_ssl_settings *set); + static unsigned int ssl_server_context_hash(const struct ssl_server_context *ctx) { unsigned int i, g, h = 0; @@ -993,11 +997,58 @@ store = SSL_CTX_get_cert_store(ssl_ctx); load_ca(store, set->ssl_ca, load_xnames ? &xnames : NULL); } + ssl_proxy_ctx_set_crypto_params(ssl_ctx, set); SSL_CTX_set_info_callback(ssl_ctx, ssl_info_callback); + return xnames; +} + +static void +ssl_proxy_ctx_set_crypto_params(SSL_CTX *ssl_ctx, + const struct master_service_ssl_settings *set) +{ +#if !defined(OPENSSL_NO_ECDH) && OPENSSL_VERSION_NUMBER >= 0x10000000L && OPENSSL_VERSION_NUMBER < 0x10002000L + EC_KEY *ecdh; + int nid; + const char *curve_name; +#endif if (SSL_CTX_need_tmp_RSA(ssl_ctx)) SSL_CTX_set_tmp_rsa_callback(ssl_ctx, ssl_gen_rsa_key); SSL_CTX_set_tmp_dh_callback(ssl_ctx, ssl_tmp_dh_callback); - return xnames; +#if !defined(OPENSSL_NO_ECDH) + /* In the non-recommended situation where ECDH cipher suites are being + used instead of ECDHE, do not reuse the same ECDH key pair for + different sessions.

[Dovecot] dovecot.index disappeared
by Metro Domain Admin 10 Jul '13

10 Jul '13

Hello, One of my users just mysteriously lost all files from his inbox. I have "mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename" but couldn't find any evidence of accidental file or folder deletion. I logged in to find that ~user/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index and its backup were tiny, only 552 bytes, when the folder had thousands of messages. Other folders were left intact. We are running 2.1.15 (mdbox) on Ubuntu 12.10 using ext4. The system was rebooted about 10 days before and the full INBOX was definitely seen since the reboot. I'm just looking for ideas about what might have happened. Thanks, Tony

by Dieter Knopf 09 Jul '13

09 Jul '13

Hello, i'm using Dovecot since a long time but now I need to share folders for global mail adresses like info@ and support@ between all users. What is the right way to share this mailboxes between many users (everyone with own read flag). My config for location is: mail_location = maildir:/home/vmail/%d/%n:INDEX=/home/vmail-indexes/%d/%n And now i have a folder like /home/vmail/bar.com/foo for sharing... Thanks!

I was not able to find specific help for configuring the crt file for CaCert. I gleaned from examples the following order: server certificate CaCert class 3 certificate Cacert root certificate However, when I try to configure my mail reading for IMAP, Dovecot shows the following error in the log: dovecot: imap-login: Aborted login (no auth attempts): I am assuming, based on searches for this error, that my crt file is not correct but I don't know what to do at this point.

[Dovecot] namespace delivery question
by Laszlo Kiraly 04 Jul '13

04 Jul '13

Hi list, I like to have public mailboxes in addition to other private in the same domain, and manage the public mailbox permissions through acls. For example: info(a)domain.com <- public, readable by user2 user1(a)domain.com <- private user2(a)domain.com <- private The mailboxes are virtual, authentication through pam (kerberos). The public mailbox doesn't have valid kerberos account. My smtp server is exim 4.80. I set the mail delivery to lmtp. I couldn't find solution in the documentation, how can I manage the email delivery to the public namespace? There is a -m option in the lda delivery where you can give namespace prefix. Maybe it's good for this, but I couldn't find any information how can I do this with lmtp? my dovecot config: test:~# dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.0.0-1-686-pae i686 Debian squeeze/sid 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 namespace { location = sdbox:/home/vmail/public/%u prefix = public. separator = . subscriptions = no type = public } namespace inbox { inbox = yes location = sdbox:/home/vmail/private/%n mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Spam { auto = subscribe special_use = \Junk } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = . } passdb { driver = pam } plugin { acl = vfile sieve = /home/vmail/%n/.dovecot.sieve sieve_dir = /home/vmail/%n sieve_global_dir = /home/vmail/sieve } protocols = " imap lmtp sieve" service managesieve-login { inet_listener sieve { port = 4190 } service_count = 1 } ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { args = uid=1035 gid=8 home=/home/vmail/%Lu allow_all_users=yes driver = static } protocol lmtp { mail_plugins = " sieve" } protocol lda { mail_plugins = " sieve" } protocol sieve { mail_max_userip_connections = 10 managesieve_implementation_string = Dovecot Pigeonhole managesieve_logout_format = bytes=%i/%o managesieve_max_line_length = 65536 } Best regards: László Király

[Dovecot] dnsbl feature for dovecot
by John Fawcett 04 Jul '13

04 Jul '13

dnsbl's are a popular method to prevent listed ips from making connections to mta software. cf. postscreen_dnsbl_sites in postfix Would it be possible to introduce such a feature in dovecot, so that connections can be denied based on a dnsbl lookup (where the precise dnsbls used are configurable)?

I'm using dict quota like so: quota = dict:User quota::file:/[path]/quotas/%u [path]/quotas/ is a tmpfs. The idea is to do less work on disk. Other than forcing dovecot to rebuild quotas on a reboot, are there any downsides? Thanks, Ken -- Ken Anderson Pacific Internet - http://www.pacific.net

Looking at my POP3/IMAP logs, users enter wrong passwords all the time, then their mail client keeps trying to re-authenticate, giving the appearance of a slow rolling BFD. For example, I just grabbed this typical sample Jul 2 13:24:48 dovecot: imap-login: Aborted login (auth failed, 1 attempts in 5 secs): user=<x> ... Jul 2 13:26:03 dovecot: imap-login: Aborted login (auth failed, 1 attempts in 5 secs): user=<x> ... Jul 2 13:26:13 dovecot: imap-login: Aborted login (auth failed, 1 attempts in 9 secs): user=<x> ... Jul 2 13:26:37 dovecot: imap-login: Aborted login (auth failed, 1 attempts in 5 secs): user=<x> ... Jul 2 13:26:43 dovecot: imap-login: Aborted login (auth failed, 1 attempts in 5 secs): user=<x> ... Jul 2 13:27:08 dovecot: imap-login: Aborted login (auth failed, 1 attempts in 5 secs): user=<x> ... Jul 2 13:27:14 dovecot: imap-login: Aborted login (auth failed, 1 attempts in 5 secs): user=<x> ... Jul 2 13:27:30 dovecot: imap-login: Aborted login (auth failed, 1 attempts in 5 secs): user=<x> ... Jul 2 13:27:36 dovecot: imap-login: Aborted login (auth failed, 1 attempts in 5 secs): user=<x> ... Jul 2 13:27:51 dovecot: imap-login: Aborted login (auth failed, 1 attempts in 5 secs): user=<x> ... Brute force attempts are more intense, so I think these rules can be set harder to not risk plunking your users into blacklist hell. Also, some common role account (that don't exist on my system e.g. "admin") will trigger an immediate blacklist here -- an easy way to shortcut the process. > I feel your pain and frustration. I do not believe there is an RBL list > of offending IP's for brute force attacks ... Maybe http://www.blocklist.de/en/index.html I use it for ssh BFD blocking, and it detects 2/3 of the IPs trying to do attempts. On their web page, they also list FTP, Web, and Mail login brute forcers, although I'm not sure whether "Mail" logins means IMAP, POP, SMTP-AUTH, or all of them. You can also integrate this with fail2ban so that not only can you use it to block, but can also contribute to the global detection of brute forcers. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Released Pigeonhole v0.4.1 for Dovecot v2.2.4.
by Stephan Bosch 03 Jul '13

03 Jul '13

Hello Dovecot users, Now that I am not preoccupied anymore, I quickly release a new version of Pigeonhole for Dovecot v2.2. This consists mainly of bug fixes. One new feature is that the Sieve plugin will try to pass temporary failures (e.g. from mail storage) back to LDA/LMTP as much as possible. However, this change turned out a little bigger than I would have liked, so experiment with it a bit before you deploy it in production. Changelog v0.4.1: + Added support for handling temporary failures. These are passed back to LDA/LTMP to produce an appropriate response towards the MTA. - Sieve storage: Removed PATH_MAX limitation for active symlink. This caused problems for GNU/Hurd. - Fixed line endings in X-Sieve headers added by redirect command. - ManageSieve: Fixed '[' ']' stupidity for response codes (only happened before login). - Fixed setting name in example-config/conf.d/20-managesieve.conf. - Sieve extprograms plugin: Fixed interaction between pipe command and remote script service. The output from the script service was never read, causing a broken pipe error at the script service. Apparently, this was broken since the I/O handling for extprograms was last revised. - Fixed assertion failure due to datastack problem in message header composition. The release is available as follows: http://www.rename-it.nl/dovecot/2.2/dovecot-2.2-pigeonhole-0.4.1.tar.gz http://www.rename-it.nl/dovecot/2.2/dovecot-2.2-pigeonhole-0.4.1.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] Creating an authenticated user master user
by Chris Bullock 03 Jul '13

03 Jul '13

dovecot --version 1.1.18 mbox format We are trying to migrate from dovecot to another imap server and need some help migrating the user data to the new server. We have written a perl script to migrate the data but it seems that we need an "authenticated or Master user" in order for the script to access the user mail boxes without the users password. We are using PAM authentication, and root does not have access to the user's mail boxes. Any help would be appreciated. Chris

[Dovecot] Who all accessed my dovecot server?
by pvsuja 03 Jul '13

Hi, I have set up a mail server with dovecot as IMAP/POP3 server, postfix as MTA and roundcube as web mail client. Other mail clients such as Thunderbird is also being used for mail access. Now as a security policy in our organization, I want to know the IP addresses of the machines from which my mail server was accessed. Is there any monitoring tools to get these details?

[Dovecot] IMAPS: Disable SSL connection without client certificate
by Ireneusz Szcześniak 02 Jul '13

02 Jul '13

I've been using Dovecot 2.1.8 on OpenBSD 5.2 i386 for about a month. It works great. Dovecot serves IMAPS only, and I'm using Thunderbird to access my mail. I configured Dovecot to allow clients that present a valid certificate when establishing SSL connection. I configure my Thunderbird for SSL/TLS connection with normal password. It works fine. However, with my config anybody can connect to my server without presenting a certificate: > openssl s_client -connect server:993 > (...) > * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS > ID ENABLE IDLE AUTH=PLAIN] Dovecot ready. Luckily, after connecting without a certificate logging fails: > a001 login iszczesniak password > a001 NO [ALERT] Client didn't present valid SSL certificate *QUESTION: Is there a way in Dovecot to disable establishing an SSL connection without a client certificate?* My complete config is : # dovecot -n # 2.1.8: /etc/dovecot/dovecot.conf # OS: OpenBSD 5.2 i386 auth_ssl_require_client_cert = yes mail_location = maildir:~/archive/mail mbox_write_locks = fcntl mmap_disable = yes namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Sent { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = bsdauth } protocols = imap service imap-login { inet_listener imap { port = 0 } } ssl_ca = </etc/ssl/certs/cacertcrl.pem ssl_cert = </etc/ssl/cert.pem ssl_key = </etc/ssl/private/key.pem ssl_verify_client_cert = yes userdb { driver = passwd } verbose_ssl = yes protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep tb-lsub-flags } protocol pop3 { pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } -- Ireneusz (Irek) Szczesniak http://www.irkos.org

[Dovecot] Doubt the relationship between NTLM and Kerberos.
by Maria Jose Yañez Dacosta 01 Jul '13

01 Jul '13

Could someone explain to me what role does the Authenticating Kerberos NTLM in Authenticating NTLM explained in http://wiki.dovecot.org/HowTo/ActiveDirectoryNtlm ? Not understand that relationship between NTLM and Kerberos?. I have to configure thunderbird with simple password method and leave the password to be blank or have to use the gssapi? Although gssapi not supported by windows right? You have to generate a keytab for imap server against AD? I should create in windows and copy it to linux where I have my imap server? I appreciate someone can explain this. Thank you!. -- Maria José

Re: [Dovecot] Samba4 and user auth

The password field > in your query is userPassword or am I wrong here? the password field is hidden (only the user can see it) by default, and not stored as a unix-friendly value (anything a crypt() would understand) what I use is auth_bind (which uses user-supplied password to bind to the LDAP directory). what it means is that on every login there are 2 lookups (first one using your "service" DN to find the user DN, second one with your user DN to check the password) that also means that you need a password format that your LDAP can understand (mostly a plaintext password, or NTLM if your mail server is a Samba domain member). As long as you only offer IMAP/SSL I dont think plaintext (as in "auth_mechanisms = plain") is an issue, security wise. as far as the service account (the one that is used to look up users) goes, I am using the default option (setting "dn" and "dnpass" variables), which I think is a simple bind. it is possible that it only works because Samba4 and dovecot run on the same machine.

The timestamp is not correlated to any of my cron jobs. How can I find out what caused this? Of course with Dovecot shut down Postfix refused to send mail as there was no auth service available.

[Dovecot] Samba4 and user auth
by Carsten Laun-De Lellis 01 Jul '13

01 Jul '13

Hi all I am trying to set up an email Server with a Samba4 AD as user Directory. Does anybody know a good how-to to setup user auth against AD ? Or could anyone tell me how to do it? I am having an email Server up and running with openldap but want to change to Samba4 AD, because of the openchange Integration. I would appreciate any help on this topic. -- Mit freundlichem Gruß Carsten Laun-De Lellis Hauptstrasse 13 D-67705 Trippstadt Phone: +49 6306 992140 Fax: +49 6306 992142 Mobile: +49 151 27530865 email: carsten.delellis(a)delellis.net http://www.linkedin.com/in/carstenlaundelellis [1] Links: ------ [1] http://www.linkedin.com/in/carstenlaundelellis

[Dovecot] LIST command -- quoting of folder names
by Eric Abrahamsen 01 Jul '13

01 Jul '13

If I open an imap connection to a local maildir installation like so: /usr/lib/dovecot/imap -o mail_location=maildir:$HOME/.mail/account/:LAYOUT=fs And issue: c list "" * This is the result (this is a gmail account): * LIST (\HasChildren) "/" [Gmail] * LIST (\HasNoChildren) "/" [Gmail]/Spam * LIST (\HasNoChildren) "/" [Gmail]/Starred * LIST (\HasNoChildren) "/" [Gmail]/Trash * LIST (\HasNoChildren) "/" [Gmail]/Drafts * LIST (\HasNoChildren) "/" "[Gmail]/Sent Mail" * LIST (\HasNoChildren) "/" [Gmail]/Important * LIST (\HasNoChildren) "/" INBOX Only "[Gmail]/Sent Mail" is quoted. This is messing up gnus, my MUA, which truncates other folder names after the / separator. Examples of testing I've seen online have shown all folder names quoted, which would allow things to work correctly here. Is this something I can affect with local configuration, or is there some other solution? Would removing "LAYOUT=fs" affect this issue? Thanks!

[Dovecot] Issues when compiling dovecot antispam on debian wheezy
by Joan 28 Jun '13

28 Jun '13

I've been trying to compile the latest version of dovecot-antispam, and it doesn't work, the latest patch fixes compilation for dovecot versions greater than 2.1.16 but the packaged version in debian is 2.1.7 and doesn't provide the DOVECOT_PREREQ macro. It seems there are some solutions: 1) Rollback to the last working version so it can be used on wheezy 2) Open a bug report in debian to see if they can backport the macro here ( http://www.dovecot.org/list/dovecot-cvs/2013-March/022903.html) 3) Use the packaged version from debian 4) .. What's your opinion?

[Dovecot] Zero-sized Maildir files and index corruption on over-quota
by Edgar Fuß 28 Jun '13

28 Jun '13

We are using Postfix as an MTA delivering via Dovecot's LDA (with sieve). We also use Dovecot as a POP/IMAP server. Mail storage is Maildir on NFS, indexes are stored locally. Quotas are FS quotas enforced by the NFS server. The Dovecot version is 1.2.11. Recently, for one user being over quota, some attempts to deliver mail bounced as expected while some others resulted in zero-sized Maildir files. I can verify zero-sized files in cur, while I cannot tell whether they were already zero-sized in new. However, since nobody except Dovecot is accessing the mail storage, it's either Dovecot's LDA or Dovecot's IMAP producing the zero-sized files. Logs show successful delivery (deliver: stored mail into mailbox 'INBOX') but ,,Corrupted index cache file /var/db/dovecot/indexes/XXX/.INBOX/dovecot.index.cache: Corrupted virtual size for uid=YYY: 0 != NNNN'' alerts on IMAP access. It looks like all mails which correctly got bounced are >64KB while those resulting in zero-sized files are <64KB (there is one >32KB). My first guess would be that maybe for large files, write() fails, while for small ones, close() fails or there is some buffering involved for large files.

[Dovecot] traffic statistics
by Martin Waschbüsch 28 Jun '13

28 Jun '13

Hi all, Does anyone know a good tool to gather traffic statistics for imap? And what level of logging would I need to set for dovecot to make it happen. Ideally this would be able to filter per domain, too. ;-) Thanks a lot, Martin -- Martin Waschbüsch IT-Dienstleistungen Lautensackstr. 16 80687 München Telefon: +49 89 57005708 Fax: +49 89 57868023 Mobil: +49 170 2189794 martin(a)waschbuesch.de http://martin.waschbuesch.de

[Dovecot] Dovecot NTLM Authentication
by Matthew Larsen 27 Jun '13

27 Jun '13

I'm working on getting authentication for Postfix smtpd clients working with Dovecot. I've got both plain text and GSSAPI mechanisms working. Winbind also works for shell access and the command line test work fine. If I can get NTLM authentication working I can use Postfix as a drop in replacement for a MS MTA I want get rid of. I'm hoping the community might be able to offer some insight into what I'm missing to get NTLM authentication working with Dovecot and Postfix. Something related to winbind I suspect. When I use the NTLM mechanism I get this " auth: Debug: client out: FAIL#0112" message in my maillog file. Nothing seems to show up in the winbind files for this. ---- log file from NTLM mechanism used ---- Jun 26 17:02:53 SBSMTPNV05 postfix/smtpd[2221]: connect from nvit01b.mydomain.com[10.20.2.0] Jun 26 17:02:53 SBSMTPNV05 dovecot: auth: Debug: client in: AUTH#0112#011NTLM#011service=smtp#011nologin#011lip=10.20.4.12#011rip=10.20.2.0#011resp=TlRM...A= Jun 26 17:02:53 SBSMTPNV05 dovecot: auth: Debug: client out: CONT#0112#011TlRM....A Jun 26 17:02:53 SBSMTPNV05 dovecot: auth: Debug: client in: CONT#0112#011TlRM....Q= Jun 26 17:02:53 SBSMTPNV05 dovecot: auth: winbind(?,10.20.2.0): user not authenticated: NT_STATUS_UNSUCCESSFUL Jun 26 17:02:55 SBSMTPNV05 postfix/smtpd[2221]: warning: nvit01b.mydomain.com[10.20.2.0]: SASL NTLM authentication failed: TlRM....A Jun 26 17:02:55 SBSMTPNV05 dovecot: auth: Debug: client out: FAIL#0112 Jun 26 17:02:59 SBSMTPNV05 postfix/smtpd[2221]: disconnect from nvit01b.mydomain.com[10.20.2.0] ------------------------------------------ ---- log file from GSSAPI mechanism used ----- Jun 26 17:02:08 SBSMTPNV05 postfix/smtpd[2221]: connect from nvit01b.mydomain.com[10.20.2.0] Jun 26 17:02:08 SBSMTPNV05 dovecot: auth: Debug: auth client connected (pid=2221) Jun 26 17:02:08 SBSMTPNV05 dovecot: auth: Debug: client in: AUTH#0111#011GSSAPI#011service=smtp#011nologin#011lip=10.20.4.12#011rip=10.20.2.0#011resp=YIIN....

Dear Team, Due to some reasons I need to move vmail folder to another drive. I tried to do rsync & I was able to copy all the files and structure with same old date and time stamp. I made symbolic link and new mail flow was fine but problem is, all the mail boxes started downloading old mails again . Is there any way where I can copy location of the folder without this problem.

[Dovecot] How to manage email with an ISP restricted mailbox size?
by Tom Atkins 26 Jun '13

26 Jun '13

Sorry if this is a bit off topic but I'm hoping list members here might have some ideas. Aim: use ISP provided email with restricted inbox size but keep an IMAP accessible archive of emails (including 'sent' messages) on a remote server. Scenario: - Don't want to run my own SMTP server - Have free ISP email with 1Gb mailbox limit and spam filtering that works well - Have remote server with plenty of disk space - Want to use remote server for IMAP access to archive of email to avoid 1Gb ISP mailbox limit Options I tried: 1. Use ISP email via IMAP and periodically backup / archive messages to remote server with something like mbsync / isync to maildir format. Delete old messages on ISP server safe in knowledge they are backed up on my server. QUESTION: how to access those archives via IMAP (read only is OK)? 2. Use ISP email for sending messages only. Use Getmail / Fetchmail to move messages to remote server and run Dovecot there. I tried using Getmail to do this but couldn't figure out how to keep copies of 'Sent' and 'Draft' messages if the email client was configured to read via IMAP on one server and send via SMTP to another server. Any thoughts on how best to achieve my aims? Thanks, Tom.

[Dovecot] Help installing Dovecot 1.0 on Debian 6.0.7

Hi, Could someone please let me know if I can get the pre-built binaries for Dovecot 1.0 for Debian 6.0? If I do "apt-get install dovecot...", I am getting Dovecot v1.2.5 installed, but it doesn't like the existing Dovecot 1.0 configuration I have, and due to some urgency, I am trying to avoid migrating the configuration to the new structure / requirements.

[Dovecot] Dovecot 2 and managesieve
by Darek 25 Jun '13

25 Jun '13

Having some difficulty finding out whether managesieve is still a separate package (not seeing it in the FreeBSD ports tree, only one for 1.x) or whether it was integrated into the main 2.x package. I've only been using 1.2.x up to now, and trying to document a system install. So is it in the main distribution now? -- Darek

[Dovecot] NTLM Authentication with Dovecot and Postfix
by Matthew Larsen 25 Jun '13

25 Jun '13

I'm trying to get NTLM authentication working with Dovecot to authenticate Postfix SMTP clients. I can authenticate postfix smtp clients using the plain text login mechanism via Dovecot and winbind. However, using the NTLM mechanism gives me an error in my maillog that says: "dovecot: auth: winbind(?,10.20.2.0): user not authenticated: NT_STATUS_UNSUCCESSFUL". At this point, I'm rather stuck. It appears PAM and winbind work for authenticating with AD because it works with the plain text mechanism, but I'm missing something with the NTLM authentication method.

[Dovecot] Configuring TLS 1.2
by Phillip Odam 25 Jun '13

25 Jun '13

Hi I'm running dovecot 2.1.6 and am trying to configure it to require TLS 1.2. So far I've only got as far as getting TLS 1.0 going. In the config file <dovecot root>/etc/dovecot/conf.d/10-ssl.conf, I've tried setting ssl_protocols to values like TLSv1.2:!TLSv1:!SSL3 but without any success. Attempts to google this matter turns up results for dovecot v1.2 as opposed to configuring TLS 1.2 in dovecot And having a look over the mailing list archive hasn't turned anything up thus far. Any pointers would be greatly appreciated. Thanks Phillip

[Dovecot] Sieve file permission problem
by Zoltan Lippai 25 Jun '13

25 Jun '13

Hi folks, I am using dovecot 2.1.7 with the ManageSieve plugin which works great. Recently I set up Afterlogic webmail on my server (the community version) and it has a nice UI to manage the sieve settings. It uses port 2000 to communicate with dovecot via the ManageSieve plugin. Also, dovecot uses Maildirs to store the messages. The problem is that the permissions on the files that store the sieve rules are to strict. I am talking about the "sieve" directory and the .dovecot.sieve file. The sieve folder has a chmod 700 and the .dovecot.sieve is chmod 600. Both are owned by vmail:mail If I delete these two items, then the rules can be saved via the web interface. Then these files are created but for some reason the ManageSieve plugin can't modify them. Here is the output of dovecot -n: http://pastebin.com/4eqyBKCA Can you help me out on this? Thanks a lot! Zoltan

[Dovecot] Quota based on LDAP group
by Pavel Herrmann 25 Jun '13

25 Jun '13

Hi I have a setup where my dovecot (2.0, if that makes a difference) authenticates against an LDAP directory. In my scenario, I have two types of users, lets call them "normal" and "privileged". What I need is for the normal user to have a fixed quota, but for the priviledged to have none. (The users do not exist on the underlying system, so I cant do quota based on FS) The issue is that my LDAP is actually an AD, and there is a fair amount of new accounts over the time (in other words, I cannot use LDAP attribute for storing quota, because the AD tools don't understand it, and I would have to add it manually for each new account). The approach I had in mind is using quota based on user group (I do have groups representing both normal and priviledged users), but I cannot find a way to set it up in dovecot. Am I missing something or does dovecot not support LDAP groups as attribute source? thanks Pavel Herrmann

[Dovecot] Warning recipient when message delivery fails due to over-quota
by Ben Johnson 24 Jun '13

24 Jun '13

I'm working to configure automated quota notifications in Dovecot and am wondering if it is possible to send a warning message to a user when message delivery fails because the user is over-quota. I already have the following directives configured: quota_warning = storage=95%% quota-warning 95 %u %d quota_warning2 = storage=80%% quota-warning 80 %u %d quota_warning3 = -storage=100%% quota-below below %u %d These seem to function as expected, but the problem I'm facing is that when a message is large enough to take the user's quota from, say, 84% to over 100%, the message is rejected (as expected), but the user is never warned that a message failed to be delivered because it would have put him over 100% usage. I suppose that I'm looking for a trigger that is tripped when delivering the message *would* put the user over-quota (as opposed to *does in fact* put the user over). The sender receives an automated rejection message already. I'm wondering if the recipient can be warned at the same time. (I'm not concerned about further increasing the user's quota consumption with the warning message; I would set noenforcing to 1.) Is this possible? Any help is much appreciated. Thanks in advance. -Ben

Hi, I am looking for a way to sync only selected files/mailbox'es using dsync. Am I using the dsync -m option incorectly? It looks like it's being ignored.

[Dovecot] dovecot-lda - dovecot: quota-warning: Error: lda: Fatal: Unknown argument
by Ben Johnson 24 Jun '13

24 Jun '13

Hi, everyone, I'm attempting to configure automated quota warnings for users and have hit a snag. The script I'm using is as follows: --------------------------------------------------------------------- #!/bin/sh PERCENT=$1 MAILBOX=$2 DOMAIN=$3 cat << EOF | /usr/lib/dovecot/dovecot-lda -d $USER -o "plugin/quota=dict:user::file:/var/vmail/%d/%n/.quotausage" From: postmaster@$DOMAIN Subject: Email quota warning - mailbox over $PERCENT% full [...] --------------------------------------------------------------------- When the script is triggered, here's what appears in the log: --------------------------------------------------------------------- Jun 24 11:16:53 host dovecot: quota-warning: Error: lda: Fatal: Unknown argument: plugin/quota=dict:user::noenforcing:file:/var/vmail/%d/%n/.quotausage Jun 24 11:16:53 host dovecot: master: Error: service(quota-warning): child 22415 returned error 64 --------------------------------------------------------------------- If I paste the same on the command line, the message is delivered, as expected: /usr/lib/dovecot/dovecot-lda -d user(a)example.com -o "plugin/quota=dict:user::noenforcing:file:/var/vmail/%d/%n/.quotausage" -p /tmp/test.txt The problem seems to be that the -o switch isn't being interpreted correctly when dovecot-lda is called from within the script. -o is the correct switch, yes? From the manual at http://wiki2.dovecot.org/LDA : -o name=value: Override a setting from dovecot.conf. You can give this parameter multiple times. What am I missing here? Is some shell script escaping or similar required? Thanks for any tips! -Ben

[Dovecot] NTLM Authentication for Postfix SMTP clients
by Matthew Larsen 24 Jun '13

24 Jun '13

I'm trying to get NTLM authentication working with Dovecot to authenticate Postfix SMTP clients. I can authenticate postfix smtp clients using the plain text login mechanism through winbind. However, using the NTLM mechanism gives me an error in my maillog that says: "dovecot: auth: winbind(?,10.20.2.0): user not authenticated: NT_STATUS_UNSUCCESSFUL". At this point, I'm rather stuck. It appears PAM and winbind work for authenticating with AD because it works with the plain text mechanism, but I'm missing something with the NTLM authentication method. Any suggestions as to what I've got wrong, or other logging I can turn up / examine that might shed some light on this? When I use the LOGIN mechanism I see this in the mail logging and the message is relayed: Jun 21 13:12:58 SBSMTPNV05 postfix/smtpd[1501]: connect from nvit01b.mydomain.com[10.20.2.0] Jun 21 13:12:58 SBSMTPNV05 dovecot: auth: Debug: auth client connected (pid=1501) Jun 21 13:12:58 SBSMTPNV05 dovecot: auth: Debug: client in: AUTH#0111#011PLAIN#011service=smtp#011nologin#011lip=10.20.4.12#011rip=10.20.2.0#011resp=AG[...snip...]g== Jun 21 13:12:58 SBSMTPNV05 dovecot: auth: Debug: pam(myusername,10.20.2.0): lookup service=dovecot Jun 21 13:12:58 SBSMTPNV05 dovecot: auth: Debug: pam(myusername,10.20.2.0): #1/1 style=1 msg=Password: Jun 21 13:12:58 SBSMTPNV05 dovecot: auth: Debug: client out: OK#0111#011user=myusername Jun 21 13:12:58 SBSMTPNV05 postfix/smtpd[1501]: 54EAF8059B: client=nvit01b.mydomain.com[10.20.2.0], sasl_method=PLAIN, sasl_username=myusername Jun 21 13:12:58 SBSMTPNV05 postfix/cleanup[1504]: 54EAF8059B: message-id=<51C4B3C8.30008(a)domain1.com> Jun 21 13:12:58 SBSMTPNV05 postfix/qmgr[1499]: 54EAF8059B: from=<someone(a)domain1.com>, size=2700, nrcpt=1 (queue active) Jun 21 13:12:58 SBSMTPNV05 postfix/smtpd[1501]: disconnect from nvit01b.mydomain.com[10.20.2.0] Jun 21 13:12:59 SBSMTPNV05 postfix/smtp[1505]: 54EAF8059B: to=<someone(a)gmail.com>, relay=gmail-smtp-in.l.google.com[74.125.25.27]:25, delay=1.2, delays=0.23/0.04/0.16/0.72, dsn=2.0.0, status=sent (250 2.0.0 OK 1371845579 wf5si3786287pab.138 - gsmtp) Jun 21 13:12:59 SBSMTPNV05 postfix/qmgr[1499]: 54EAF8059B: removed I also see this in the secure log: Jun 21 13:12:58 SBSMTPNV05 auth: pam_unix(dovecot:auth): authentication failure; logname= uid=0 euid=0 tty=dovecot ruser=myusername rhost=10.20.2.0 user=myusername Jun 21 13:12:58 SBSMTPNV05 auth: pam_winbind(dovecot:auth): getting password (0x00000010) Jun 21 13:12:58 SBSMTPNV05 auth: pam_winbind(dovecot:auth): pam_get_item returned a password Jun 21 13:12:58 SBSMTPNV05 auth: pam_winbind(dovecot:auth): user 'myusername' granted access Jun 21 13:12:58 SBSMTPNV05 auth: pam_winbind(dovecot:account): user 'myusername' granted access However, when I switch the mechanism to NTLM in the Thurnderbird MUA I see this: Jun 21 13:15:46 SBSMTPNV05 postfix/smtpd[1506]: connect from nvit01b.mydomain.com[10.20.2.0] Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libauthdb_ldap.so Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libmech_gssapi.so Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: auth client connected (pid=1506) Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: client in: AUTH#0111#011NTLM#011service=smtp#011nologin#011lip=10.20.4.12#011rip=10.20.2.0#011resp=TlRMT[...snip...]A= Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: client out: CONT#0111#011TlRMT[[...snip...]A Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: client in: CONT#0111#011TlRMT[...snip...]A= Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: winbind(?,10.20.2.0): user not authenticated: NT_STATUS_UNSUCCESSFUL Jun 21 13:15:48 SBSMTPNV05 postfix/smtpd[1506]: warning: nvit01b.mydomain.com[10.20.2.0]: SASL NTLM authentication failed: TlRMT[...snip...]A Jun 21 13:15:48 SBSMTPNV05 dovecot: auth: Debug: client out: FAIL#0111 Jun 21 13:15:49 SBSMTPNV05 postfix/smtpd[1506]: disconnect from nvit01b.mydomain.com[10.20.2.0] with nothing in the secure log and I don't see anything show up in the winbind logs either.

[Dovecot] Calling dovecot-lda from within Antispam pipe script (bash) seems to have no effect
by Ben Johnson 24 Jun '13

24 Jun '13

Hello, I'm attempting to configure the Dovecot Antispam plug-in on Ubuntu 12.04 LTS with Dovecot 2.0.19. Everything seems to be in order with one considerable exception: when my pipe script (a simple Bash shell script) calls the dovecot-lda executable, absolutely nothing seems to result. If I copy/paste the exact same command into the terminal, the mail is delivered to the target mailbox, as expected. Here's my pipe script: http://pastebin.com/DBXAZqsN When I move a message from INBOX -> Junk, or from Junk -> INBOX, the pipe script is called, and here's the output: --------------------------------------------------------------- 31465-start (--debug --username=amavis --ham) Checking if the command-line input argument string (--debug --username=amavis --ham) contains the string "ham" or "spam" Mode is "HAM" Calling (as user vmail) '/usr/lib/dovecot/deliver -d "sa-training(a)example.com" -m "Training.HAM" -p "/tmp/sendmail-msg-31465.txt"' 31465-end --------------------------------------------------------------- But, for some reason, the call to "/usr/lib/dovecot/deliver" doesn't seem to do anything. If I copy the above output and paste it into the terminal: /usr/lib/dovecot/deliver -d "sa-training(a)example.com" -m "Training.HAM" -p "/tmp/sendmail-msg-31465.txt" Dovecot does indeed deliver the message. This works whether I execute the above command as "root" or "vmail". Why does this command have no effect when called from within the pipe script? Here is my "doveconf -n" output: # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-042stab076.8 x86_64 Ubuntu 12.04.2 LTS auth_mechanisms = plain login disable_plaintext_auth = no listen = *,[::] log_timestamp = "%Y-%m-%d %H:%M:%S " mail_privileged_group = vmail passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { antispam_backend = pipe antispam_debug_target = syslog antispam_pipe_program = /usr/bin/sa-learn-pipe.sh antispam_pipe_program_args = --debug;--username=amavis antispam_pipe_program_notspam_arg = --ham antispam_pipe_program_spam_arg = --spam antispam_pipe_tmpdir = /tmp antispam_spam_pattern_ignorecase = SPAM;JUNK antispam_trash_pattern_ignorecase = trash;Deleted * antispam_verbose_debug = 1 quota = dict:user::file:/var/vmail/%d/%n/.quotausage quota_rule2 = Trash:storage=+100M quota_rule3 = Junk:ignore quota_warning = storage=95%% quota-warning 95 %u %d quota_warning2 = storage=80%% quota-warning 80 %u %d quota_warning3 = -storage=100%% quota-below below %u %d sieve = /var/vmail/%d/%n/.sieve } protocols = imap pop3 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 quota-below { executable = script /usr/local/bin/quota-below.sh user = vmail } service quota-warning { executable = script /usr/local/bin/quota-warning.sh user = vmail } 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 antispam } protocol pop3 { mail_plugins = quota pop3_uidl_format = %08Xu%08Xv } protocol lda { info_log_path = /var/log/dovecot-lda.log log_path = /var/log/dovecot-lda-errors.log mail_plugins = sieve quota } Thank you, -Ben

[Dovecot] Dovecot + SELinux permission problems
by Johnny 24 Jun '13

24 Jun '13

Hi, I have set-up dovecot on a F17 box and am encountering weirdnesses with SELinux (who isn't??). Again, I am trying to refrain from disabling SWLinux all together, however tempting, but am stuck in troubleshooting and hope for some ideas...

[Dovecot] tables between dovecot and postfix and a paradoxical question
by Mohsen Pahlevanzadeh 23 Jun '13

23 Jun '13

Dear all, I read we create the following table in wiki2 : CREATE TABLE users ( userid VARCHAR(128) NOT NULL, domain VARCHAR(128) NOT NULL, password VARCHAR(64) NOT NULL, home VARCHAR(255) NOT NULL, uid INTEGER NOT NULL, gid INTEGER NOT NULL ); But i read the following text in the official postfix documentation : "DO create tables with each matching item as a key and with an arbitrary value. With SQL databases it is not uncommon to return the key itself or a constant value." ref: http://www.postfix.org/mysql_table.5.html How can i combine together? --mohsen

[Dovecot] Problem with virtual user mailbox initialization
by Denis Kasak 22 Jun '13

22 Jun '13

Hello, I'm trying to set up a postfix/dovecot server where postfix hands over incoming mail to dovecot using lmtp virtual transport via a Unix socket. Dovecot is then supposed to write the mail to /var/mail/<domain>/<user>/ using a virtual users setup. It seems to work except for failing when the mailbox is supposed to be initially created: Jun 22 03:25:04 lmtp(2400, dkasak(a)foo.org) Error: user dkasak(a)foo.org: Initialization failed: Namespace '': mkdir(/var/mail/foo.org/dkasak) failed: Permission denied (euid=5000(postman) egid=5000(postman) missing +w perm: /var/mail, we're not in group 6(mail), dir owned by 0:6 mode=0775) As can be seen from the error message, I've set mail_uid and mail_gid to account/group postman. /var/mail/ is empty and owned by root:mail so I've also set mail_privileged_group = mail. I was under the impression that mail_privileged_group is used precisely for these situations (when dotlocking or initial creation of the mailbox fail due to insufficient privileges), but it still doesn't work. If I either set mail_gid = mail, or set mail_access_groups = mail, or create foo.org/ owned by postman:postman by hand, it works as expected. Here is the complete configuration: # 2.2.2: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 9.1-RELEASE-p4 i386 ufs base_dir = /var/run/dovecot/ mail_gid = postman mail_location = maildir:/var/mail/%d/%n/:LAYOUT=fs mail_privileged_group = mail mail_uid = postman 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 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 = separator = / type = private } passdb { args = scheme=CRYPT username_format=%u /etc/dovecot/users driver = passwd-file } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap lmtp service auth-worker { user = $default_internal_user } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } service imap-login { inet_listener imap { port = 143 } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0660 user = postfix } } ssl = required ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = username_format=%u /etc/dovecot/users default_fields = quota_rule=*:storage=2G driver = passwd-file } protocol imap { mail_plugins = " notify mail_log" } Any ideas? -- Denis Kasak

You didn't provide the analogous output from the interactive shell to see the differences (for example, USER might be being used), but from your later strace, I guess CONFIG_FILE has something to do with it. These threads seems relevant http://www.dovecot.org/list/dovecot/2011-May/059127.html http://www.mail-archive.com/dovecot@dovecot.org/msg38349.html That thread poster solved his problem by commenting out service imap-postlogin { # user = $default_internal_user ... } but I have no idea if it works, or whether it's a good idea, for your case.

[Dovecot] Getting NTLM authentication for Postfix SMTP clients to work
by Matthew Larsen 22 Jun '13

22 Jun '13

I'm trying to get NTLM authentication working with Dovecot to authenticate Postfix SMTP clients. I can authenticate postfix smtp clients using the plain text login mechanism through winbind. However, using the NTLM mechanism gives me an error in my maillog that says: "dovecot: auth: winbind(?,10.20.2.0): user not authenticated: NT_STATUS_UNSUCCESSFUL". At this point, I'm rather stuck. It appears PAM and winbind work for authenticating with AD because it works with the plain text mechanism, but I'm missing something with the NTLM authentication method. Any suggestions as to what I've got wrong, or other logging I can turn up / examine that might shed some light on this? When I use the LOGIN mechanism I see this in the mail logging and the message is relayed: Jun 21 13:12:58 SBSMTPNV05 postfix/smtpd[1501]: connect from nvit01b.mydomain.com[10.20.2.**0] Jun 21 13:12:58 SBSMTPNV05 dovecot: auth: Debug: auth client connected (pid=1501) Jun 21 13:12:58 SBSMTPNV05 dovecot: auth: Debug: client in: AUTH#0111#011PLAIN#011service=**smtp#011nologin#011lip=10.20.**4 .12#011rip=10.20.2.0#011resp=**AG[...snip...]g== Jun 21 13:12:58 SBSMTPNV05 dovecot: auth: Debug: pam(myusername,10.20.2.0): lookup service=dovecot Jun 21 13:12:58 SBSMTPNV05 dovecot: auth: Debug: pam(myusername,10.20.2.0): #1/1 style=1 msg=Password: Jun 21 13:12:58 SBSMTPNV05 dovecot: auth: Debug: client out: OK#0111#011user=myusername Jun 21 13:12:58 SBSMTPNV05 postfix/smtpd[1501]: 54EAF8059B: client= nvit01b.mydomain.com[**10.20.2.0], sasl_method=PLAIN, sasl_username=myusername Jun 21 13:12:58 SBSMTPNV05 postfix/cleanup[1504]: 54EAF8059B: message-id=< 51C4B3C8.30008(a)**domain1.com <51C4B3C8.30008(a)domain1.com>> Jun 21 13:12:58 SBSMTPNV05 postfix/qmgr[1499]: 54EAF8059B: from=< someone(a)domain1.com>, size=2700, nrcpt=1 (queue active) Jun 21 13:12:58 SBSMTPNV05 postfix/smtpd[1501]: disconnect from nvit01b.mydomain.com[10.20.2.**0] Jun 21 13:12:59 SBSMTPNV05 postfix/smtp[1505]: 54EAF8059B: to=< someone(a)gmail.com>, relay=gmail-smtp-in.l.google.**com<http://gmail-smtp-in.l.google.com/>[74.125.25.27]:25, delay=1.2, delays=0.23/0.04/0.16/0.72, dsn=2.0.0, status=sent (250 2.0.0 OK 1371845579 wf5si3786287pab.138 - gsmtp) Jun 21 13:12:59 SBSMTPNV05 postfix/qmgr[1499]: 54EAF8059B: removed I also see this in the secure log: Jun 21 13:12:58 SBSMTPNV05 auth: pam_unix(dovecot:auth): authentication failure; logname= uid=0 euid=0 tty=dovecot ruser=myusername rhost=10.20.2.0 user=myusername Jun 21 13:12:58 SBSMTPNV05 auth: pam_winbind(dovecot:auth): getting password (0x00000010) Jun 21 13:12:58 SBSMTPNV05 auth: pam_winbind(dovecot:auth): pam_get_item returned a password Jun 21 13:12:58 SBSMTPNV05 auth: pam_winbind(dovecot:auth): user 'myusername' granted access Jun 21 13:12:58 SBSMTPNV05 auth: pam_winbind(dovecot:account): user 'myusername' granted access However, when I switch the mechanism to NTLM in the Thurnderbird MUA I see this: Jun 21 13:15:46 SBSMTPNV05 postfix/smtpd[1506]: connect from nvit01b.mydomain.com[10.20.2.**0] Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/**libauthdb_ldap.so Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/**libdriver_sqlite.so Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/**libmech_gssapi.so Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: auth client connected (pid=1506) Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: client in: AUTH#0111#011NTLM#011service=**smtp#011nologin#011lip=10.20.**4. 12#011rip=10.20.2.0#011resp=**TlRMT[...snip...]A= Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: client out: CONT#0111#011TlRMT[[...snip...**]A Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: client in: CONT#0111#011TlRMT[...snip...]**A= Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: winbind(?,10.20.2.0): user not authenticated: NT_STATUS_UNSUCCESSFUL Jun 21 13:15:48 SBSMTPNV05 postfix/smtpd[1506]: warning: nvit01b.mydomain.com[10.20.2.**0]: SASL NTLM authentication failed: TlRMT[...snip...]A Jun 21 13:15:48 SBSMTPNV05 dovecot: auth: Debug: client out: FAIL#0111 Jun 21 13:15:49 SBSMTPNV05 postfix/smtpd[1506]: disconnect from nvit01b.mydomain.com[10.20.2.**0] with nothing in the secure log and I don't see anything show up in the winbind logs either.

[Dovecot] Sieve Plugin Setup
by Denny Jones 22 Jun '13

22 Jun '13

I've got an existing setup that I want to add Sieve filtering to. I'm on QmailToaster: qmailadmin-toaster-1.2.16-1.4.0 I using Dovecot version 2.0.11 I'm looking for a good tutorial for installing Sieve Rules functionality on an existing system. Anybody know of one? Anybody else done this? Do I just install the latest Dovecot-sieve plugin release with wget, etc? What kind of configuration can I expect to have to go through. Do I have to reconfigure Dovecot to work in conjunction with the Sieve plugin? I'm hoping to find someone else has done this that can help me navigate the waters so-to-speak. Thanks in advance, Denny

Have you also checked the environment variables? I think dovecot-lda gets some information from them.

[Dovecot] Would attempting plaintext auth repeatably cause a DOS and server to crash?
by Hugh Davenport 21 Jun '13

21 Jun '13

Hey All, I'm just wondering whether this is what caused my server to crash. Started last night in NZ land. Jun 20 19:22:11 elm dovecot: imap-login: Disconnected (tried to use disallowed plaintext auth): user=<>, rip=attackerip, lip=10.0.0.3, session=<0C8LzpDfZQDINsQC> occasionally get Jun 20 19:22:52 elm dovecot: imap-login: Disconnected (no auth attempts in 1 secs): user=<>, rip=attackerip, lip=10.0.0.3, session=<bHdz0JDfpwDINsQC> or in 0 secs last at Jun 20 19:26:24 elm dovecot: imap-login: Disconnected (tried to use disallowed plaintext auth): user=<>, rip=attackerip, lip=10.0.0.3, session=<1MUR3ZDfcwDINsQC> and a minute later the server lost contact to the world. When I checked a bit later, the underlying host machine (dovecot runs on a VM (KVM)) had been powered off. Now, here in NZ land, there was also a crazy storm last night, and lots of brown outs. There could potentially of been a surge that killed it, but the UPS was still running fine when I started it again. The "attack" lasted around 4 minutes, in which there was 1161 lines in the log for a single attacker ip, and no other similar logs previously. Would this be enough to kill not only the VM running dovecot, but the underlying host machine? All up to date with patches, running debian stable (wheezy). dovecot-core debian package version 1:2.1.7-7 dovecot version 2.1.7 I notice there is a version 2.2.3 out, but not in debian yet. Could this fix this issue? I don't particularly want to have it happen again :D. Any thoughts? Cheers, Hugh

[Dovecot] Allowing clients to test their Sieve scripts
by Frerich Raabe 21 Jun '13

21 Jun '13

Hi, One thing which came up repeatedly is that clients using the IMAP server I run (using Dovecot 2.1) wonder whether they broke their Sieve scripts, i.e. it often goes like "I don't know whether I just didn't receive any mail, or whether my filters broke. Can you check the logs?". I then usually just run the sieve-test binary (part of the Pigeonhole distribution) and send them the output. However, I was wondering - is there maybe a way for them to try it themselves? Like, maybe a tiny web server which just prints a form asking for a mail file and a sieve script, and then it runs sieve-script and prints the output of that? I wonder how other people do that. -- Frerich Raabe - raabe(a)froglogic.com www.froglogic.com - Multi-Platform GUI Testing

[Dovecot] dovecot enterprise release

20 Jun '13

Hi all, Not sure if this is the right place to ask, but...: On the dovecot enterprise release pages, only debian 6 compatibility is shown. Are there any plans to support wheezy? (as 7 is stable now, and we are running it...) Regards, Mourik Jan

[Dovecot] Patch for pigeonhole 0.4.0 avoiding PATH_MAX
by Svante Signell 19 Jun '13

19 Jun '13

Hi, I recently downloaded and built dovecot-2.2.2 and dovecot-2.2-pigeonhole-0.4.0 on GNU/Linux and GNU/Hurd. The changes needed will be sent to the Debian maintainer shortly. Latest Debian release is 2.1.7-7 and dovecot-2.1-pigeonhole-0.3.1. When building dovecot-2.2.2 there were no PATH_MAX problems on GNU/Hurd, thank you for that. However, pigeonhole 0.4.0 had one remaining PATH_MAX construct. The attached patch solves this problem. It it good enough to be accepted upstream? (According to the description of t_malloc, free is not needed, right?) Thanks, Svante Signell

[Dovecot] A common, read-only IMAP INBOX for all accounts
by Gus 19 Jun '13

19 Jun '13

Hi, since I had no luck finding people available on IRC, I hope someone here can provide me with some answers to, hopefully, 2 simple questions (and have the solution recorded in the archives for everyone with the same need). A little background, as the subject says it - I want to have a single INBOX shared among all the accounts on my system, where only one account would have writing rights, and all the rest would only be able to read the messages. Note this is different than providing a shared mailbox in addition to an INBOX - I actually want the shared INBOX to be the one and only folder that users can see and read as they will not be receiving any personal mails on this system. Naturally, I would also want that each account keeps track of read/unread messages independently of others. So, this is what I came up with (showing the relevant part of configuration only): # Per-user mail root and private/shared INBOX namespace userdb { driver = static args = uid=vmail gid=vmail home=/var/vmail/users/%u } namespace { type = private separator = / prefix = location = maildir:/var/vmail/public:INDEX=~/public inbox = yes } # The ACL contents of /var/vmail/public/dovecot-acl user=admin lrwstipekx anyone lrs Now, this actually results in exactly what I want (apart from a problem I'll describe below), but I'm not sure if it's the right way to do it. So the questions: 1. I have doubts that this solution could cause problems with dot file locking or dovecot data files corruption in the /var/vmail/public mailbox/directory when multiple users access the box simultaneously (and this could be thousands of users in production). Is this a valid concern and have I gone completely wrong with this solution, or there should be no problem with locking and I can keep it this way? If this is not the way to do it, can someone advise on the proper configuration that would achieve the same result, if it's possible at all (or what are the alternatives if it can't be done). 2. For testing purposes, I used a perl script (using the Maildir::Lite module) to create a test message in this mailbox (it gets stored in the new/ subdirectory, as I suppose it should). Now this message shows up as "unread" for all accounts, however when I read it in an IMAP client and then refresh the mailbox, it shows up as unread again. Per-user INDEX directory is writable and I see some files created there by dovecot, so shouldn't they contain the \Seen flags that indicate the message has been read? Is this maybe a client problem and how can I check that dovecot actually saves the flag correctly? The dovecot version I'm using is 2.0.9 (from the CentOS 6.x repositories). Thanks in advance and kind regards, Tin

[Dovecot] dovecot creating unknown users
by Yann Shukor 19 Jun '13

19 Jun '13

Hi We recently installed a dovecot postfix roundcube debian wheezy serverIt is now in production and we are feeling our way as we progressivelyadd new users to this local server. I noticed that dovecot is creating user directory structures for unknown users withinour domain in /var/vmail, even though we have setup a static users.conf db file. I tried omiting the "allow_all_users=yes" parameter but that doesn't seem to be linked to this issue Sorry if this has been asked a number of times already Is there an easy way to search the archives of this mailinglist ?

[Dovecot] v2.2.3 released
by Timo Sirainen 18 Jun '13

18 Jun '13

http://dovecot.org/releases/2.2/dovecot-2.2.3.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.3.tar.gz.sig This is a pretty important upgrade for v2.2 users, because of the IMAP ENVELOPE reply fix. * LDA/LMTP: If new mail delivery first fails with "temporary failure", tempfail the whole delivery instead of falling back to delivering the mail to INBOX. (Requires new Pigeonhole as well.) * doc/solr-schema.xml was updated to Solr v4.x format. Also the default analyzers were changed, hopefully for the better. Note that the schema can't be changed for existing Solr indexes without rebuilding everything. * Solr plugin does only soft commits from now on. You'll need a cronjob to send a hard commit command to it every few minutes. + Added %N modifier for variables as %H-like "new hash" + sdbox, mdbox: Support POP3 message order field (for migrations) + Added mailbox { driver } to specify a different mail storage format for the mailbox than generally used within the namespace. + Added initial lib-sasl library for client side SASL support. Currently supports only PLAIN, LOGIN and plugins. Used currently by IMAP and POP3 proxying when authenticating to the remote server. - IMAP: If subject contained only whitespace, Dovecot returned an ENVELOPE reply with a huge literal value, effectively causing the IMAP client to wait for more data forever. - IMAP: Various URLAUTH fixes. - imapc: Various bugfixes and improvements - pop3c: Various fixes to make it work in dsync (without imapc) - dsync: Fixes to syncing subscriptions. Fixes to syncing mailbox renames.

[Dovecot] Mailbox conversion/importing

I've been tasked with importing a large bunch of mbox folders (about 500) into an existing mdbox setup in Dovecot 2.1 As far as I can see, dsync "mirror" or "backup" are both inappropriate ways of doing this. Does anyone have any suggestions about how I could proceed? Thanks in advance

[Dovecot] Problem redirecting email using pigeonhole 0.4.0 (with patch)
by Andriy Syrovenko 18 Jun '13

18 Jun '13

Hello, Starting from the version 0.4.0 Pigeonhole adds "X-Sieve" and "X-Sieve-Redirected-From" headers ending them with CR+LF, and then copies the original message (including original headers) ending the lines with LF-only. This causes troubles at least if using Exim (I have not checked with other MTAs)- original message gets dropped, and only the new pigeonhole-generated headers are sent out. The attached file fixed the problem for me. --- dovecot-2.2-pigeonhole-0.4.0.orig/src/lib-sieve/cmd-redirect.c 2013-04-07 01:57:26.000000000 +0300 +++ dovecot-2.2-pigeonhole-0.4.0/src/lib-sieve/cmd-redirect.c 2013-06-05 03:22:53.000000000 +0300 @@ -344,9 +344,9 @@ string_t *hdr = t_str_new(256); /* Prepend sieve headers (should not affect signatures) */ - rfc2822_header_write(hdr, "X-Sieve", SIEVE_IMPLEMENTATION); + rfc2822_header_append(hdr, "X-Sieve", SIEVE_IMPLEMENTATION, FALSE, NULL); if ( recipient != NULL ) - rfc2822_header_write(hdr, "X-Sieve-Redirected-From", recipient); + rfc2822_header_append(hdr, "X-Sieve-Redirected-From", recipient, FALSE, NULL); o_stream_send(output, str_data(hdr), str_len(hdr)); } T_END; Best regards, Andrey.

[Dovecot] Dovecot 2.2.2: doveadm user doesn't honor -x option
by Axel Luttgens 17 Jun '13

17 Jun '13

Hello, 1. Considering a user_query similar to this one: SELECT ... FROM ... WHERE CASE '%s' WHEN 'lmtp' THEN ... and issuing following command: doveadm user -x service=lmtp someuser(a)example.com the log shows: SELECT ... FROM ... WHERE CASE 'doveadm' WHEN 'lmtp' THEN ... and the query of course fails. The same config with Dovecot 2.1.16 yields expected results. 2. This is more a question. Issuing above command first writes this to the log: prefetch(someuser(a)example.com): passdb didn't return userdb entries, trying the next userdb Is there really an attempt to make use of the prefetch database? If yes, under which circumstances could it succeed? TIA, Axel

[Dovecot] Trash plugin
by Jason Pfingstmann 17 Jun '13

17 Jun '13

Hello all! I tried to post this earlier today, but it's stuck in a moderator queue for being too long, so here's a shorter version (mod, please delete the pending message from me, if you read this). I'm new to dovecot and just finished setting everything up. It's a postfix + dovecot + myql + spamassassin + postgrey virtual mail server. The issue I'm having (1 of 2) is that the Trash plugin isn't working, over-quota mail is being rejected despite a large piece that would bring it under quota with room to spare for the piece being delivered that is in the Trash folder. My configs (postconf -n, doveconf -n, trash.conf): http://pastebin.com/vFJ0rfZ6 It may be unrelated, but it seems postgrey isn't running either, but maybe those are partially tied together? Thanks for all your help! Jason Pfingstmann

[Dovecot] Trash plugin
by Jason Pfingstmann 17 Jun '13

17 Jun '13

Hello! This is my first dovecot install, which I put together by mixing and matching pieces of various online howtos (fortunately, Dovecot doesn't seem to be overly complex - a big plus). I've got it mostly working, but the trash plugin doesn't seem to be working right. Below are configs and some logs. Any thoughts? Also, any suggestions regarding my configuration? I can post other items for troubleshooting if they'd be helpful. -Jason Pfingstmann Here's my doveconf -n: # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-358.6.2.el6.x86_64 x86_64 CentOS
