[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

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.

[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. I'm not sure if I should bother adding something to be distributed with Dovecot, since I guess most people would want to modify it in some way anyway.

It'd be useful for us if the IMAP passdb could be used as a prefetch userdb. The remote IMAP server could respond with something like * OK key=value * OK key=value SEQ OK [CAPABILITY ...] Logged in. Or * OK <some JSON key value pairs> SEQ OK [CAPABILITY ...] Logged in. Would anyone else find this useful?

[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... Anyway, let's ask quota-status again: $ sudo -u _postfix telnet /_ROOT/var/spool/postfix/private/quota-policyd Password: Trying /_ROOT/var/spool/postfix/private/quota-policyd... Connected to (null). Escape character is '^]'. recipient=john.doe(a)example.com size=10000 action=OK ^] telnet> quit Connection closed. In the log: dovecot[11050]: auth: Debug: userdb out: USER 1 john.doe(a)example.com quota_rule=*:storage=5k dovecot[11050]: quota-status: Debug: auth input: john.doe(a)example.com quota_rule=*:storage=5k dovecot[11050]: quota-status: Debug: Added userdb setting: plugin/quota_rule=*:storage=5k dovecot[11050]: quota-status(john.doe(a)example.com): Debug: Effective uid=999, gid=999, home=/_Mailstores/john.doe dovecot[11050]: quota-status(john.doe(a)example.com): Debug: Quota root: name=Quota utilisateur backend=dict args=john.doe:proxy::sql_quota dovecot[11050]: quota-status(john.doe(a)example.com): Debug: Quota rule: root=Quota utilisateur mailbox=* bytes=5120 messages=0 dovecot[11050]: quota-status(john.doe(a)example.com): Debug: Quota grace: root=Quota utilisateur bytes=512 (10%) dovecot[11050]: quota-status(john.doe(a)example.com): Debug: dict quota: user=john.doe, uri=proxy::sql_quota, noenforcing=0 dovecot[11050]: quota-status(john.doe(a)example.com): Debug: fs: root=/_Mailstores/john.doe/mboxes, index=, indexpvt=, control=, inbox=/_Mailstores/john.doe/mboxes/inbox, alt= It is to be noted that the config server is now launched as expected, but that the dict server still isn't. Trying a dirsize backend instead of the dict backend doesn't help. The problem seems to be circumscribed to the interaction with the quota backend since, for example, querying quota-status for an unknown recipient yields an expected "action=REJECT Unknown user". Hence my last question, after having tried a lot of things for several days now, with no more success: Q3. What am I doing wrong?

[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

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?

[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?

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

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>

Well, the background process is hogging CPU and RAM while it basically does nothing. And when it's running as root there is always the danger of privilege escalation.

[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!

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] Please help with : undefined symbol: mail_deliver_save_open
by Markus Kalb 28 Jul '13

Greetings dovecot-mailing list! after upgrading from debian squeeze -> debian wheezy and therefore making the big dovecot jump from 1.x to 2.x we are stuck with one final(?) error that we can't get fixed. During login attempts the following is written to the logfiles. Error: dovecot: imap: Error: dlopen(/usr/lib/dovecot/modules/lib90_sieve_plugin.so) failed: /usr/lib/dovecot/libdovecot-sieve.so.0: undefined symbol: mail_deliver_save_open Searching the mailinglist and google in general the only thing i could find was that this error could be connected to loading the sieve plugin outside of lda. But as you can see in the attached config dump, we only load it inside the lda protocol block. ciao markus Our setup: > dovecot --version 2.1.7 > dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-686-pae i686 Debian 7.1 auth_debug = yes auth_mechanisms = plain login digest-md5 cram-md5 auth_verbose = yes mail_debug = yes mail_plugins = acl fts fts_solr mail_shared_explicit_inbox = no 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 imapflags notify namespace { hidden = no list = children location = maildir:/home/lists/.mail/:CONTROL=%h/.mail/private/.imap/shared/control:INDEX=%h/.mail/private/.imap/shared/index prefix = lists/ separator = / subscriptions = no type = shared } namespace { hidden = yes list = no location = maildir:/home/security/.mail/:CONTROL=%h/.mail/private/.imap/shared/control:INDEX=%h/.mail/private/.imap/shared/index prefix = security/ separator = / subscriptions = no type = shared } namespace { hidden = yes list = children location = maildir:/home/dsys/.mail/:CONTROL=%h/.mail/private/.imap/shared/control:INDEX=%h/.mail/private/.imap/shared/index prefix = duales_system/ separator = / subscriptions = no type = shared } namespace inbox { hidden = no inbox = yes list = yes location = mbox:%h/.mail/private:INBOX=/var/mail/%u 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=DIGEST-MD5 username_format=%u /etc/dovecot/passwd driver = passwd-file } plugin { acl = vfile:/etc/dovecot/acls:cache_secs=300 sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = +imapflags +notify } protocols = " imap sieve" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } } service imap-login { inet_listener imap { port = 143 } } ssl_cert = </etc/ssl/certs/SERVER.pem ssl_key = </etc/ssl/private/SERVER.key userdb { args = username_format=%u /etc/dovecot/passwd default_fields = mail_plugins=sieve system_groups_user=%u driver = passwd-file } protocol lda { mail_plugins = acl fts fts_solr sieve } protocol imap { mail_max_userip_connections = 20 mail_plugins = acl fts fts_solr } # dpkg -l '*dovecot*' |grep ii | cut -c 0-60 ii dovecot-antispam 2.0+20120225-3 ii dovecot-core 1:2.1.7-7 ii dovecot-imapd 1:2.1.7-7 ii dovecot-ldap 1:2.1.7-7 ii dovecot-managesieved 1:2.1.7-7 ii dovecot-sieve 1:2.1.7-7 ii dovecot-solr 1:2.1.7-7

[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?

[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.

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).

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

[Dovecot] zlib error when running doveadm
by Michael Long 22 Jul '13

22 Jul '13

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

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).

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?

[Dovecot] avoid log message when using nagios check
by lluis 12 Jul '13

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!

[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

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.

[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] Fault in dovecot 2.1.17
by Adrian Stoica 11 Jul '13

The system hang, linux from scratch. I have changed the live kernel from linux-2.6.35.4 to linux-2.6.32.61 , to see if the fault still occurs. The kernel 2.6.35.4 was working fine with all version up to dovecot 2.1.12 , from which i made update to 2.1.17. dovecot -n # 2.1.17: /usr/dovecot21/etc/dovecot/dovecot.conf # OS: Linux 2.6.32.61 i686 auth_cache_negative_ttl = 1 secs auth_cache_size = 2 M auth_failure_delay = 4 secs auth_mechanisms = plain login digest-md5 cram-md5 auth_worker_max_count = 100 base_dir = /var/run/dovecot/ default_client_limit = 4096 default_internal_user = vmail default_login_user = nobody default_process_limit = 256 deliver_log_format = mail delivery from=%f subject=%s msgid=%m: %$ dict { acl = mysql:/usr/dovecot21/etc/dovecot/dovecot-dict-sql.conf.ext } disable_plaintext_auth = no first_valid_uid = 1 lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes listen = * mail_location = maildir:~/Maildir mail_plugins = " quota acl trash notify mail_log" 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 { hidden = no list = children location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes list = 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 = / subscriptions = yes type = private } passdb { args = /usr/dovecot21/etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { acl = vfile acl_defaults_from_inbox = yes acl_shared_dict = proxy::acl autocreate = Trash autocreate2 = Drafts autocreate3 = Sent autosubscribe = Trash autosubscribe2 = Drafts autosubscribe3 = INBOX autosubscribe4 = Sent mail_log_events = delete mailbox_delete mailbox_rename mail_log_fields = box subject from msgid size quota = maildir:User quota quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=95%% quota-warning 90 %u quota_warning3 = storage=85%% quota-warning 85 %u sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_max_redirects = 10 trash = /usr/dovecot21/etc/dovecot/dovecot-trash.conf.ext } postmaster_address = postmaster(a)dacris.net protocols = imap quota_full_tempfail = yes rejection_subject = Rejected: %s: %r service auth { unix_listener auth-client { mode = 0666 user = vmail } unix_listener auth-userdb { mode = 0666 user = vmail } } service dict { unix_listener dict { user = vmail } } service imap-login { process_min_avail = 4 } service imap-postlogin { executable = script-login /bin/imap.sh unix_listener imap-postlogin { mode = 01232 } } service imap { executable = imap imap-postlogin process_limit = 1024 vsz_limit = 1 G } service quota-warning { executable = script /bin/quota_warning.sh unix_listener quota-warning { user = vmail } user = vmail } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /usr/dovecot21/etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lda { mail_plugins = " quota acl trash notify mail_log sieve autocreate" } protocol imap { imap_client_workarounds = delay-newmail mail_max_userip_connections = 20 mail_plugins = " quota acl trash notify mail_log imap_quota imap_acl" } Log from kernel: Jul 11 10:14:01 mail kernel: BUG: Bad page map in process imap-login pte:c926b025 pmd:4597c067 Jul 11 10:14:01 mail kernel: page:c2f2ed60 count:1 mapcount:-1 mapping:ec5a03a0 index:0x4ab Jul 11 10:14:01 mail kernel: page flags: 0x80020068(uptodate|lru|active|mappedtodisk) Jul 11 10:14:01 mail kernel: addr:b73f4000 vm_flags:08000075 anon_vma:(null) mapping:e289ec88 index:7b Jul 11 10:14:01 mail kernel: vma->vm_ops->fault: filemap_fault+0x0/0x2fa Jul 11 10:14:01 mail kernel: vma->vm_file->f_op->mmap: ext4_file_mmap+0x0/0x39 Jul 11 10:14:01 mail kernel: Pid: 22889, comm: imap-login Not tainted 2.6.35.4 #2 Jul 11 10:14:01 mail kernel: Call Trace: Jul 11 10:14:01 mail kernel: [<c1078901>] ?
