Empty mailboxes
by Daniel Miller 24 Sep '14

24 Sep '14

This is driving me nuts. I need to rebuild a server - got a notification the main drive is failing, and it's been a year or two, so it's time. Got a new drive, fresh install of Ubuntu Tantric, started installing everything needed. Data stored on a RAID array - nicely available separate from the boot/operation drive. Did a fresh compile of Dovecot, copied over the configs from the old drive, mounted the RAID...and... Dovecot starts, authenticates users - and shows empty mailboxes. Nothing shown. Full panic - reboot on old drive. All mails present. Change back - no mail. Executing "doveadm user -u username" seems to give valid results. Mailbox location appears correct (using mdbox). I setup uid/gid the same - I thought it was a rights issue but everything looks correct. What can I do to try to find the stupid mistake I'm making? -- Daniel

quota recalc problem for big maildirs
by Dawid Stawiarski - nazwa.pl 24 Sep '14

24 Sep '14

hi, we use dovecot 2.2.13, and we've lately started using maildir quota (previously fs quota was used, right now it's "quota = maildir:User quota" changed from "quota = fs:User quota:user:inode_per_mail"). When the change was applied we didn't manually forced generating maildirsize files. So, when the first deliver happens (or the file grows larger then 5KB) it starts quota recalc. However for users with big maildirs, receiving email every couple of seconds, there are tens of delivery processes each doing its own recalc (as they open file for APPEND and there's no locking). What's even worse, after all the stats and getdents (it takes a lot of IO for 60GB account with 2M emails), deliver makes stat on 'new' dir and detects changes after which it unlinks freshly created maildirsize. So possibly this will never be finished as every process drops its own work. The same thing happened when we checked the native dovecot LMTP server (every connection has its own forked process - each running independently of the others). Is it a known unwanted "feature" of maildir quota (and we should use dict quota instead) or a bug that will be fixed? cheers, Dawid Stawiarski

Re: director

The configuration use to be in /etc/dovecot, and the working dir is /var/run/dovecot. You should store your configuration file in the /etc/dovecot. The dovecot.conf file can be copied to dovecot-backend.conf and dovecot-director, for example, and you will use '-c' argument of dovecot binary to load on or another. If you do this, you will need create two separated working dir, that will be defined in base_dir on each configuration file.

This is a quick run down of my setup: 3 servers running iRedMail (this is a package that installs dovecot 2.1.7, postfix, and LDAP). All three servers share an NFS backend. The same 3 servers are also sitting behind a load balancer. What I want to do is use these three servers as directors and mail servers. So from the replies I have gotten I understand that I need to create 2 config files 1 for director and 1 for dovecot. Now my next question is do these config files need to be stored in /etc/dovecot or /var/run/dovecot? Also is creating the second config file as simple as copying and renaming the dovecot.conf file? > > On Sep 23, 2014, at 2:26 PM, Eduardo Ramos <eduardo(a)freedominterface.org> wrote: > >> Hi, >> >> In fact you don't NEED a director.

sieve redirect to foreign email gets “Relay access denied”
by Henry Stack 23 Sep '14

23 Sep '14

I have a postfix mail server with sql authentication and I want to implement sieve on it. Sieve is working relative good, rules who contain 'fileinto' are executed perfectly. The problem is the redirect to other servers. I configured a rule in Sieve to redirect any email containing "redirect" in subject to a specified foreign destination. # So practically a email coming from sender(a)live.de for the local user testuser(a)server.net should be redirected to destination(a)gmail.com when the subject contains "redirect" if header :contains ["subject"] ["redirect"] {redirect "destination(a)gmail.com"; stop;} when I test it I get the following log entry /postfix/smtpd[32114]: NOQUEUE: reject: RCPT from mail.server.net[xx.xx.xx.xx]: 554 5.7.1 <destination(a)gmail.com>: Relay access denied; from=<sender(a)live.de> to=<destination(a)gmail.com> proto=ESMTP helo=<mail.server.net>/ How can I tell postfix to let dovecot/sieve relay the email?

Announce: Plugin for iOS Push Email support
by Stefan Arentz 23 Sep '14

23 Sep '14

I’ve been hacking on a personal side project to support native iOS Push Email in Dovecot. This is specifically for people who are migrating their mail away from OS X Server while keeping their existing Push Email functionality. Native Push Email has some great advantages: it speeds up email notifications (usually within seconds of being handled by dovecot-lda) and it improves battery life since the native notifications flow over a single highly optimized connection to Apple’s infrastructure. Although this is at version 0.1, it is working pretty well for me and I am looking for some additional testers that are interested. Please note that it is not possible to use this project without legally running a copy of OS X Server. You can purchase OS X Server on the Mac App Store or download it for free if you are a registered Mac or iOS developer. This feature is enabled by two projects: https://github.com/st3fan/dovecot-xaps-plugin <https://github.com/st3fan/dovecot-xaps-plugin> https://github.com/st3fan/dovecot-xaps-daemon <https://github.com/st3fan/dovecot-xaps-daemon> Both projects contain a README that describes how to get things going. I have only developed and tested on Ubuntu 12.04.5 so ideally you run the same version if you are interested in playing with this project. You will need to compile some code and not be afraid of a little admin work. I am also interested in a code review. The Dovecot plugin API is barely documented and I had to guess a lot of things by looking at other plugins. An extra pair of eyes specifically on that code would be awesome. Also from a security perspective. Please file bugs! S.

> BTW: It would be nice, if I could just 'git clone' dovecot. Hi, Thomas, I happily use Felipe Contreras' excellent git-hg bridge, as I am far happier in a GIT environment than an Hg one: https://github.com/felipec/git/wiki/git-remote-hg The workflow couldn't be much easier, in particular if you set up a few aliases for the common sequences of tasks. $ hg clone http://hg.dovecot.org/dovecot-2.2 $ git clone "hg::/home/phil/dovecot-2.2" dovecot-2.2-git $ cd dovecot-2.2-git $ git checkout -b hacking $ # work... $ cd ../dovecot-2.2 $ hg pull -u $ cd ../dovecot-2.2-git $ git checkout master $ git rebase master hacking $ # more work... (OK, my workflow includes pushing too ;-) ) Hope that helps. Cheers, Phil

by Robert Watson 23 Sep '14

I'm having a great deal of difficulty with integrating dovecot 2.0.9 with a new installation of samba4 4.1.11 and would appreciate anyones help who has this working. *Problem 1:* if dn= cn=Administrator,dc=ourhome,dc=net with dnpass = ***** ---------------I get NT_STATUS_LOGON_FAILURE but dn = "Administrator(a)ourhome.net" with dnpass = **** works I guess I shouldn't complain but why doesn't the first one work? *Problem 2:* can't seem to get a working set of usr_attrs/user_filter,pass_attrs/pass_filter to authenticate *dovecot-ldap.conf :* uris = ldap://localhost:389 dn = "Administrator(a)ourhome.net" dnpass = **** tls = no ldap_version = 3 base = cn=Users,dc=ourhome,dc=net scope = subtree user_filter = (&(objectClass=user)(sAMAccountName=%u)) user_attrs = sAMAccountName=user,userPassword=password,=mail=maildir:/var/vmail/%Ld/%n, =home=/var$ pass_filter = (&(objectClass=user)(sAMAccountName=%u)) pass_attrs = sAMAccountName=user,userPassword=password *dovecont.message log output:* *2014-09-22 14:44:50 auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth* *2014-09-22 14:44:50 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libauthdb_ldap.so* *2014-09-22 14:44:50 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_mysql.so* *2014-09-22 14:44:50 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_pgsql.so* *2014-09-22 14:44:50 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so* *2014-09-22 14:44:50 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libmech_gssapi.so* *2014-09-22 14:44:50 auth: Debug: auth client connected (pid=5316)* *2014-09-22 14:45:00 auth: Debug: client in: AUTH 1 PLAIN service=imap secured lip=127.0.0.1 rip=127.0.0.1 lport=143 rport=35148 resp=AEpvaG5Eb2UASm9obkRvZQ==* *2014-09-22 14:45:00 auth: Debug: ldap(JohnDoe,127.0.0.1): pass search: base=cn=Users,dc=ourhome,dc=net scope=subtree filter=(&(objectClass=user)(sAMAccountName=JohnDoe)) fields=sAMAccountName,userPassword* *2014-09-22 14:45:00 auth: Debug: ldap(JohnDoe,127.0.0.1): result: sAMAccountName(user)=JohnDoe* *2014-09-22 14:45:00 auth: Info: ldap(JohnDoe,127.0.0.1): No password returned (and no nopassword)* *2014-09-22 14:45:00 auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth* *2014-09-22 14:45:00 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libauthdb_ldap.so* *2014-09-22 14:45:00 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_mysql.so* *2014-09-22 14:45:00 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_pgsql.so* *2014-09-22 14:45:00 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so* *2014-09-22 14:45:00 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libmech_gssapi.so* *2014-09-22 14:45:00 auth: Debug: pam(JohnDoe,127.0.0.1): lookup service=dovecot* *2014-09-22 14:45:00 auth: Debug: pam(JohnDoe,127.0.0.1): #1/1 style=1 msg=Password: * *2014-09-22 14:45:02 auth: Info: pam(JohnDoe,127.0.0.1): unknown user* *2014-09-22 14:45:04 auth: Debug: client out: FAIL 1 user=JohnDoe*

dsync annoyances
by Alan McGinlay 23 Sep '14

23 Sep '14

Hi! Every time I run dsync for a user against an old Cyrus server, the users mailbox in Dovecot increases by several hundred MB, these are not new emails. So the first dsync run gets the whole mailbox and subsequent runs get a bunch of duplicates or what? doveadm purge clears them all out but why is dsync behaving like this? I didn't happen in previous versions (2.2.13)

[wishlist] testsuite for sieve scripts, libsievetest
by Thomas Koch 23 Sep '14

23 Sep '14

Hi, I'm writing a test suite with Haskell for my sieve script. - Just to learn Haskell. But it might become something usable. The test suite calls sieve-test and parses the output. So it would of course be much simpler for me if the output of sieve-test would be easier to parse and if I'd know what output to expect. And it would be nice, if there would be an easy way to embed libsievetest as a C library. I looked into the source and the sieve-test binary does quite a bit of setup. This might be a nice hacking project for a beginner... BTW: It would be nice, if I could just 'git clone' dovecot. Thank you for dovecot!

doveadm with multiple instances on same machine(s)
by Will Yardley 22 Sep '14

22 Sep '14

Couple questions about running doveadm with multiple instances... I have Dovecot 2.2.13 on RHEL6 running across 3 boxes, each with a director and main instance running. When I try to lookup something on the main instance (which is handling user auth) via its auth-userdb socket directly, I get an error: # doveadm auth lookup -a /var/run/dovecot-main/auth-userdb myuser doveadm(root): Error: passdb lookup failed for myuser: Configured passdbs don't support crentials lookups When I use the default lookup map, I just get the proxy settings that are configured in the director instance's authdb. # doveadm auth lookup myuser passdb: myuser user : myuser proxy : y nopassword: y In addition, "doveadm director map" can't map the username -I get the error: doveadm(root): Error: User listing returned failure doveadm(root): Error: user listing failed [then I get the whole list, but with <unknown> for each user] The director itself doesn't have the LDAP passdb that the main dovecot instance talks to, but I have, in the director config: service doveadm { inet_listener { port = 8889 } } director_doveadm_port = 8889 local 192.168.x.x/24 { doveadm_password = XXXXXX } doveadm_proxy_port = 8888 And in the main config: service doveadm { inet_listener { port = 8888 } } local 192.168.x.x/24 { doveadm_password = XXXXXXX ## same password as above }

sieve redirect to foreign email gets “Relay access denied”
by Henry Stack 22 Sep '14

22 Sep '14

I have a postfix mail server with sql authentication and I want to implement sieve on it. Sieve is working relative good, rules who contain 'fileinto' are executed perfectly. The problem is the redirect to other servers. I configured a rule in Sieve to redirect any email containing "redirect" in subject to a specified foreign destination. # So practically a email coming from sender(a)live.de for the local user testuser(a)server.net should be redirected to destination(a)gmail.com when the subject contains "redirect" if header :contains ["subject"] ["redirect"] {redirect "destination(a)gmail.com"; stop;} when I test it I get the following log entry /postfix/smtpd[32114]: NOQUEUE: reject: RCPT from mail.server.net[xx.xx.xx.xx]: 554 5.7.1 <destination(a)gmail.com>: Relay access denied; from=<sender(a)live.de> to=<destination(a)gmail.com> proto=ESMTP helo=<mail.server.net>/ How can I tell postfix to let dovecot/sieve relay the email?

Authentication using AD : bug ?
by Nicolas Cauchie 22 Sep '14

22 Sep '14

Hello, I've setup a mail server (still in test) with Postfix and Dovecot, authentication made using Active Directory. I authenticate my test user in AD well in Dovecot. However, if I change this user's password in AD, the old password still works for authentication in Dovecot and the new is working too. Is there a time to make Dovecot don't "remember" the old password or is it a bug ? Restarting Dovecot don't solve the problem. Do you already heard about this ? Please tell me what conf files you maybe need. Thanks in advance Nicolas signature -----

Re: LDAP and dovecot
by dovecot＠outputservices.com 22 Sep '14

22 Sep '14

For the record. I compiled dovecot to use the openldap libraries my openldap server uses. My email server and ldap server are on two different machines. So I just copied over my ldap libraries and placed them in the correct place and then compiled dovecot. I saw this clue in a different web page. Something about Solaris ldap libraries being bad. CPPFLAGS=-I/usr/local/openldap/include \ > LDFLAGS='-L/usr/local/openldap/lib -R/usr/local/openldap/lib' \ ./configure --prefix=/usr/local/tools/dovecot --with-ssl=openssl --with-solr --with-zlib --with-bzlib --with-ldap=yes This now allows me to authenticate with my openldap server. I am NOW able to authenticate to my ldap server. So my final configuration is: dovecot -n # 2.2.10: /usr/local/tools/dovecot/etc/dovecot/dovecot.conf # OS: SunOS 5.10 i86pc base_dir = /dovecot/var/run/dovecot log_path = /dovecot/log/log mail_location = mbox:~/posta:INBOX=/var/mail/%u:LAYOUT=maildir++:INDEX=~/posta/index:CONTROL=~/posta/control passdb { args = /dovecot/etc/dovecot/conf.d/ldap.settings driver = ldap } protocols = imap service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 } } ssl_cert = </dovecot/certs/dovecot.pem ssl_key = </dovecot/certs/dovecot.key ssl_prefer_server_ciphers = yes userdb { args = /dovecot/etc/dovecot/conf.d/ldap.settings driver = ldap } /dovecot/etc/dovecot/conf.d/ldap.settings hosts = ldap.outputservices.com tls = no auth_bind = yes ldap_version = 3 base = dc=ldap,dc=outputservices,dc=com Thank you all.

X-DOVECOT capabilities
by Timo Sirainen 22 Sep '14

22 Sep '14

Dovecot has a few hidden features currenly, which I know some webmails have been hardcoded to use. Maybe it would be nice to have these available in a bit more globally usable way and advertise some kind of X-DOVECOT capability? I don't really like the idea of having a ton of separate X-DOVECOT-* capabilities. Maybe instead just have X-DOVECOT-1 for the current functionality and when more is added X-DOVECOT-2 etc? Then describe in Dovecot wiki page what they actually contain. Thoughts? The current list of features are at least: - STATUS (X-SIZE): Sum of all RFC822.SIZEs in a mailbox. (More efficient than FETCHing them.) - STATUS (X-GUID): Show mailbox's GUID. - SEARCH X-SAVEDBEFORE, X-SAVEDON, X-SAVEDSINCE: Search with message's saved-timestamp. - FETCH X-SAVEDATE: Fetch message's saved-timestamp. - SEARCH & FETCH X-GUID: Search/fetch message GUID - SEARCH X-MAILBOX, FETCH X-MAILBOX, FETCH X-REAL-UID: With virtual mailboxes search/fetch the mail's physical mailbox name and message UID. - X-CANCEL <tag>: Stop a (long-running) command, which once in a while goes back to the main loop. For example SEARCH or FETCH.

how to solve : Dovecot version mismatch: Master is v2.1.7, lmtp is v2.2.13
by Dave Myers 22 Sep '14

22 Sep '14

Hello again dovecot list ;) I've recently upgraded my dovecot version from 2.1.7 to 2.2.13. both versions where installed from source. I upgraded why attempting to get lmtp working. I ultimately just coped the executable lmtp to the location that dovecot was expecting it to be in. but then the above error appeared. However when I get the info from dovecot I get the following... $ dovecot -n # 2.2.13: /usr/local/etc/dovecot/dovecot.conf so there seems to be an issue somewhere. I should note that I had copied my previous /conf.d/ files and then copied them back after the update. I guess that I have missed a switch during the build, or need to modify a line in the config somewhere that tells what the version is, but that doesn't explain why the dovecot -n returns the correct info, but the error reports something different. I am considering inserting the version_ignore=yes config option, but where should I insert it ? Thanks in advance.

dovecot´s multiple quota roots
by Andreas Kasenides 22 Sep '14

22 Sep '14

I am trying to find out how Dovecot behaves when there are multiple quota roots. I could not find something authoritative on this. For example, on a nicely running server that used fs quota I now have in 90-quota.conf > plugin { > quota = fs:Mail Quota:user:mount=/Mail > quota2 = maildir:Mail User Quota > } When I do > > doveadm quota get -u atrige01 > Quota name Type Value Limit > % > Mail Quota STORAGE 80036 204800 > 39 > Mail User Quota STORAGE 79306 - > 0 > Mail User Quota MESSAGE 304 - > 0 Apparently both STORAGE quotas values are the same. The question is which of the two is being used by Dovecot. If I insert a limit on the maildir quota which of the two will be used? I am using Dovecot 2.2.12. thank you

Thank you all for your assistance. I was able to locate another web site that mentioned I needed to compile dovecot with my openldap libraries. I then compiled dovecot in the following manner: CPPFLAGS=-I/usr/local/openldap/include \ LDFLAGS='-L/usr/local/openldap/lib -R/usr/local/openldap/lib' \ ./configure --prefix=/tmp/tocevod --with-ssl=openssl --with-solr --with-zlib --with-bzlib --with-ldap=yes This then included the openldap libraries. I tested access and now it works. ldd on /dovecot/libexec/dovecot/auth showed the openldap libraries. libdovecot.so.0 => /usr/local/tools/dovecot/lib/dovecot/libdovecot.so.0 libpam.so.1 => /usr/lib/libpam.so.1 libldap-2.4.so.2 => /usr/local/openldap/lib/libldap-2.4.so.2 libsasl.so.1 => /usr/lib/libsasl.so.1 libssl.so.0.9.7 => /usr/sfw/lib/libssl.so.0.9.7 libcrypto.so.0.9.7 => /usr/sfw/lib/libcrypto.so.0.9.7 liblber-2.4.so.2 => /usr/local/openldap/lib/liblber-2.4.so.2 libresolv.so.2 => /usr/lib/libresolv.so.2 libgen.so.1 => /usr/lib/libgen.so.1 librt.so.1 => /usr/lib/librt.so.1 libnsl.so.1 => /usr/lib/libnsl.so.1 libsocket.so.1 => /usr/lib/libsocket.so.1 libsendfile.so.1 => /usr/lib/libsendfile.so.1 libc.so.1 => /usr/lib/libc.so.1 libgcc_s.so.1 => /usr/sfw/lib/libgcc_s.so.1 libcmd.so.1 => /usr/lib/libcmd.so.1 libmd.so.1 => /usr/lib/libmd.so.1 libaio.so.1 => /usr/lib/libaio.so.1 libmp.so.2 => /usr/lib/libmp.so.2 libscf.so.1 => /usr/lib/libscf.so.1 libdoor.so.1 => /usr/lib/libdoor.so.1 libuutil.so.1 => /usr/lib/libuutil.so.1 libssl_extra.so.0.9.7 => /usr/sfw/lib/libssl_extra.so.0.9.7 libcrypto_extra.so.0.9.7 => /usr/sfw/lib/libcrypto_extra.so.0.9.7 libm.so.2 => /usr/lib/libm.so.2 Thanks again.

Dear dovecot users. I have an odd issue in that when I connect to my dovecot server from either a local or remote system I can't see my test emails (I have the impression that is is looking at the wrong location on disk). here are some details.... # dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-xen-amd64 x86_64 Debian 6.0.3 auth_debug = yes auth_debug_passwords = yes auth_mechanisms = plain login cram-md5 auth_verbose = yes auth_verbose_passwords = plain lda_mailbox_autocreate = yes log_path = /var/log/dovecot.log mail_debug = yes mail_gid = 1002 mail_home = /var/mail/virtual/%d/%n mail_location = maildir:~/mail/: mail_uid = 1002 namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = scheme=SHA512-CRYPT username_format=%u /etc/dovecot/users driver = passwd-file } protocols = imap service auth { unix_listener auth-client { mode = 0660 user = mail } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } } ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { args = username_format=%u /etc/dovecot/users driver = passwd-file } userdb { driver = passwd } verbose_ssl = yes when I connect (via openSSL from a remote system) openssl s_client -connect mail.exsportee.biz:993 CONNECTED(00000003) depth=0 C = fr, ST = coupvray, L = paris, O = exsportee, OU = facilitee, CN = scibearspace, emailAddress = david.myers(a)scibearspace.org verify error:num=18:self signed certificate verify return:1 depth=0 C = fr, ST = coupvray, L = paris, O = exsportee, OU = facilitee, CN = scibearspace, emailAddress = david.myers(a)scibearspace.org verify return:1 [.... security stuff removed....] * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN AUTH=LOGIN AUTH=CRAM-MD5] Dovecot ready. auth login "websales(a)exsportee.biz" "testPassword" auth OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS SPECIAL-USE] Logged in a list "" "*" * LIST (\HasNoChildren) "."

Support of unicode in then recipient names
by Александр Егоров 19 Sep '14

19 Sep '14

Hi Dovecot Community, We are using ltmp to deliver messages through postfix to dovecot. During testing we have found that dovecot does not understand recipient email address if it is composed from national symbols : e.g. ยจฆฟคฏข(a)xn--22cdfh1b8fsa.xn--22cdfh1b8fsa Question is are there any plans to either add native support for such email addresses or to translate it to punycode and then try to find such a recipient? -- Александр Егоров (Alexander Yegorov)

Syslog PID

Hi! How to write PIDs to syslog? Example: Sep 19 00:57:00 hostname dovecot: pop3-login: Login: user=< username(a)domainname.com >, method=PLAIN, rip=XXX.XXX.XXX.XXX, lip=XXX.XXX.XXX.XXX, mpid=14407, TLS, session=<6LYlcmYDAQC4reGs> Sep 19 00:57:00 hostname dovecot: pop3( username(a)domainname.com ): Disconnected: Logged out top=0/0, retr=0/0, del=0/0, size=0 Sep 19 00:57:09 hostname exim[14423]: 2014-09-19 00:57:09 dovecot_login authenticator failed for s16010629.onlinehome-server.info (User) [82.165.16.9]: 535 Incorrect authentication data (set_id=front) Sep 19 00:57:09 hostname exim[14424]: 2014-09-19 00:57:09 dovecot_login authenticator failed for s16010629.onlinehome-server.info (User) [82.165.16.9]: 535 Incorrect authentication data (set_id=front I need it because i write all logs to postgresql and analyze them with Adiscon LogAnalyzer. Perhaps, per-process logs entry with PID would be better.

unable to see mail when using telnet / open ssl
by Dave Myers 19 Sep '14

19 Sep '14

Dear dovecot list. I'm setting up my own VPS and working through getting mail to work. Here is my dovecot -n $dovecot -n maildir:%h/%d/%n/mail : layout=fs # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-xen-amd64 x86_64 Debian 6.0.3 auth_debug = yes auth_debug_passwords = yes auth_mechanisms = plain login cram-md5 auth_verbose = yes auth_verbose_passwords = plain lda_mailbox_autocreate = yes log_path = /var/log/dovecot.log mail_debug = yes mail_gid = 1002 mail_home = /var/mail/virtual/%d/%n mail_location = maildir:~/mail: layout=fs mail_uid = 1002 namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = scheme=SHA512-CRYPT username_format=%u /etc/dovecot/users driver = passwd-file } protocols = imap service auth { unix_listener auth-client { mode = 0660 user = mail } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } } ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { args = username_format=%u /etc/dovecot/users driver = passwd-file } userdb { driver = passwd } verbose_ssl = yes I can successfully log into dovecot using telnet and open ssl from a remote terminal, so authentication and everything is working fine. From the above dovecot -n I asume that mails should be going to /var/mail/virtual/domain/user/mail However when I view this directory I can see a number of test mails that I have sent using echo "Hello me" | mail -s "Dovecot test" $USER (see http://wiki2.dovecot.org/FindMailLocation) Why am I not seeing them when I use telnet / openSSL to log in? All help is greately appreciated. -- Tel: + 33 6 50 14 39 34 email: david.myers.24j74(a)gmail.com Addres: 22 Rue de L'Eglise 77700 Coupvray. 77700 France

negative auth cache?
by Will Yardley 19 Sep '14

19 Sep '14

I am using Dovecot 2.2.13, which doesn't yet seem to have the $auth_cache_negative parameter. Should the negative cache value honor $auth_cache_ttl then? I had a problem where some of our ldap systems were reinitialized. Some users, presumably those who tried to login while their records were returning a failure, became unable to login after the records were once again returning normally. I currently have: auth_cache_size = 5 M auth_cache_ttl = 5 mins # Not yet implemented #auth_cache_negative = 2 mins yet the problem seemed to persist for more than an hour. Also, how can I flush the cache for a non-default instance's cache using doveadm -- "doveadm auth cache flush" doesn't seem to have an '-a' option AFAICT. # doveadm auth usage: doveadm [-Dv] [-f <formatter>] auth <command> [<args>] cache flush w

LDAP and dovecot
by dovecot＠outputservices.com 19 Sep '14

19 Sep '14

At my company I have users who are now becoming remote and using their mobile devices for email. I use Solaris 10 10/09 s10x_u8wos_08a X86 as an operating system and I now need a more secure email solution than the generic sendmail / imap solution. I want to use dovecot and postfix because I have read good reports on these products for ease of setup and use. I need to use both with SSL certificates and username / passwords for both receiving and sending emails. I am having difficulty getting dovecot to work with my ldap password solution. I have read all the documentation, there is a lot of it, and find it confusing. But I have tried very hard to get the solution to work. I have not compiled postfix because I want to use the dovecot authentication solution it mentions. Therefore I need to get dovecot to work first. I have dovecot 2.2.10 & postfix 2.11.1 with openldap 2.4.33. I have tested dovecot with /etc/passwd /etc/shadow password authentication and password flat files. Those work, but not what I need. I need to use ldap so the users only have to set one password. Below is the information I have. I have created self signed SSL certificates for testing purposes. We will get real SSL certificates once everything is operational. ********* I compiled dovecot with the following command: ./configure --prefix=/usr/local/tools/dovecot --with-ssl=openssl --with-solr --with-zlib --with-bzlib --with-ldap=yes ------------------------------------------- dovecot -n # 2.2.10: /usr/local/tools/dovecot/etc/dovecot/dovecot.conf # OS: SunOS 5.10 i86pc base_dir = /dovecot/var/run/dovecot log_path = /dovecot/log/log log_timestamp = "%Y-%m-%d %H:%M:%S " mail_debug = yes mail_location = mbox:~/posta:INBOX=/var/mail/%u:LAYOUT=maildir++:INDEX=~/posta/index:CONTROL=~/posta/control passdb { args = /dovecot/etc/dovecot/tests/ldap.settings driver = ldap } protocols = imap service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 } } ssl_cert = </dovecot/certs/dovecot.pem ssl_key = </dovecot/certs/dovecot.key ssl_prefer_server_ciphers = yes userdb { args = /dovecot/etc/dovecot/tests/ldap.settings driver = ldap } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep } ------------------------------------------- /dovecot/etc/dovecot/tests/ldap.settings hosts = ldap.outputservices.com tls = no ldap_version = 3 base = dc=ldap,dc=outputservices,dc=com ------------------------------------------- If I use ldap for passwords: 2014-09-18 09:44:23 master: Info: Dovecot v2.2.10 starting up for imap 2014-09-18 09:44:33 auth: Fatal: LDAP: Buggy LDAP library returned wrong fd: 1 2014-09-18 09:44:33 master: Error: service(auth): command startup failed, throttling for 2 secs 2014-09-18 09:44:33 imap-login: Info: Disconnected: Auth process broken (disconnected before auth was ready, waited 0 secs): user=<> , rip=137.106.101.127, lip=137.106.76.215, TLS handshaking, session=<d1Nt3FgD1wCJamV/> 2014-09-18 09:44:48 master: Warning: Killed with signal 15 (by pid=18992 uid=0 code=kill) ------------------------------------------- If I use a flat file for passwords: 2014-09-18 09:42:23 master: Info: Dovecot v2.2.10 starting up for imap 2014-09-18 09:43:05 imap-login: Info: Login: user=<dave>, method=PLAIN, rip=137.106.101.127, lip=137.106.76.215, mpid=16769, TLS, se ssion=<vAny1VgDywCJamV/> 2014-09-18 09:43:05 imap(dave): Debug: Effective uid=6010, gid=131, home=/export/home/sun/dave 2014-09-18 09:43:05 imap(dave): Debug: maildir++: root=/export/home/sun/dave/posta, index=/export/home/sun/dave/posta/index, indexpv t=, control=/export/home/sun/dave/posta/control, inbox=/var/mail/dave, alt= 2014-09-18 09:43:10 imap(dave): Info: Disconnected: Logged out in=223 out=1122 2014-09-18 09:43:22 master: Warning: Killed with signal 15 (by pid=17115 uid=0 code=kill) ------------------------------------------- If I use /etc/passwd /etc/shadow for passwords: 2014-09-18 09:39:56 master: Info: Dovecot v2.2.10 starting up for imap 2014-09-18 09:40:14 imap-login: Info: Login: user=<dave>, method=PLAIN, rip=137.106.101.127, lip=137.106.76.215, mpid=13053, TLS, se ssion=<uaT5zFgDwACJamV/> 2014-09-18 09:40:14 imap(dave): Debug: Effective uid=6010, gid=131, home=/export/home/sun/dave 2014-09-18 09:40:14 imap(dave): Debug: maildir++: root=/export/home/sun/dave/posta, index=/export/home/sun/dave/posta/index, indexpv t=, control=/export/home/sun/dave/posta/control, inbox=/var/mail/dave, alt= 2014-09-18 09:41:01 imap(dave): Info: Disconnected: Logged out in=219 out=1118 2014-09-18 09:41:33 master: Warning: Killed with signal 15 (by pid=14765 uid=0 code=kill) ------------------------------------------- I am using openldap 2.4.33.

I want to stop solaris versions of sendmail and use dovecot & postfix. I am also a little confused on the mail_location setting. We use thunderbird as an email client and it sets the "local folders" just fine. But with imap it puts the Sent, Trash, Draft folders in the users "home" directory. With dovecot I have to put them in a different folder, I called it posta for now. It then makes them . Files. (.Sent, .Trash ?)

If you only want to dump a few auth cache entries, you can just authenticate with a bad password. When a different (and possibly correct password) is supplied, there will be a cache miss and the new credentials will be cached. echo "1 login someuser badpassword\n2 logout" | netcat --ssl your-imap-server:993 Joseph Tam <jtam.home(a)gmail.com>

migration from cyrus with dsync sieve problem

Exit status code 134; what is it, in the context of Dovecot Antispam plug-in?
by Ben Johnson 17 Sep '14

17 Sep '14

Hello! I just migrated from Ubuntu 12.04 LTS to 14.04 LTS and thereby from Dovecot 2.0.19 to 2.2.9. I've been using dovecot-antispam plugin with great success for the past year with 2.0.19, but after this migration, I've been seeing the exit status code 134 in the syslog when attempting to debug the Dovecot Antispam plugin not working after the migration. I have some debugging output in my pipe script; the output looks something like this: Copying message contents to temporary file for debugging purposes; file is: /tmp/sendmail-msg-7662.txt Checking if the command-line input argument string (--spam) contains the string "ham" or "spam" Mode is "SPAM" Calling (as user vmail) '/usr/lib/dovecot/deliver -d "sa-training(a)example.com" -m "Training.SPAM" -p "/tmp/sendmail-msg-7662.txt"' Exit status was 134 Yet, I'm able to copy the above command and execute it manually, via the command-line, and it works (and by "works", I mean to say that the behavior is correct and exactly as expected; I receive the "Spam" email at the designated mailbox). Here's how I'm calling it when it works perfectly well (as "root"): # su -c '/usr/lib/dovecot/deliver -d "sa-training(a)example.com" -m "Training.HAM" -p "/tmp/sendmail-msg-7460.txt"' vmail Any idea what status 134 might be or how to work around it?

replicator only starts for users who log in at least once
by Alan McGinlay 17 Sep '14

17 Sep '14

Hi! I recently setup a second with replication to the other. Both machines run ubuntu 12.04 with dovecot 2.2.13 (6bb26098a45c). All users mail accounts are currently synced manually to the first (mb1) using a dsync script, they are synchronised from a cyrus imap server. Users are still logging into the cyrus server. It appears that the only accounts that are replicated are ones who have logged into either of the dovecot servers at least once, is this how it is supposed to work? I was hoping to get full replication of all mail accounts before starting to move users into the new system. Thanks, Alan

Case sensitivity
by John Oliver 15 Sep '14

15 Sep '14

I think I've answered my last question by changing mail_location But I'm still getting duplicate mailboxes: [joliver@localhost ~]$ sudo ls -l /var/vmail/ total 8 drwx------. 3 vmail vmail 4096 Sep 11 10:30 testuser1 drwx------. 3 vmail vmail 4096 Sep 11 10:36 testUser1 The cn for my user is 'testUser1', and that's where postfix writes mail. But dovecot wants to use 'testuser1', even if I log in as 'testUser1' I suppose one answer may be to try to get postfix to always use lower-case, but in case that can't happen, how can I get dovecot to ignore case when looking for mailboxes? -- *********************************************************************** * John Oliver http://www.john-oliver.net/ * * * ***********************************************************************

Per-folder (per-mailbox) message expiration with control from client side — is it possible?
by Lev Serebryakov 15 Sep '14

15 Sep '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 I'm migrating from «old skool» solution with one mail client (MUA) on one computer, which retrieves mail via POP3, sorts it and manages it locally to installation when there are several MUAs on different devices, accessing mail via IMAP4, and all sorting and management should be server-side. Sorting is “easy”: sieve. Here are some nuisance (like, if I want to rename folder/mailbox I need to edit script manually. BTW, it looks like that such thing could be done automagically, as language is very simple and find all references to mailboxes is not too hard task), but it works. But is here good solution for expiration? I have abut 50 folders (mailboxes) and rules are very different for them. They are mostly time-based (like "last 30 days"), but some folders are count-limited ("last 2000 messages") and some folders should have time limit but non-read messages could not be deleted at all. Ok, Thunderbird almost could do it (it doesn't have “don't remove unread messages” option), but I don't want to have any meaningful configuration in MUAs, as each of it could be non-active for long time. Only thing I could find about expiration in dovecot documentation is "doveadm expunge" and helper "Expire" plugin, but it looks like very low-level solution for admins, it could not be managed from client side without direct ssh access to server and it is, in general, very inconvenient. Is here any better solution, maybe, 3rd party one? - -- // Black Lion AKA Lev Serebryakov -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQJ8BAEBCgBmBQJUFf2BXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXRGOTZEMUNBMEI1RjQzMThCNjc0QjMzMEFF QUIwM0M1OEJGREM0NzhGAAoJEOqwPFi/3EePphIQAJUlYIFgXWBcWcrejcbOFgYf op+g35YF4wfwboPkgb/mKk46V3lcjmQImcHir2fci0SCsSSfARcU1a8y4iaeSkPU l949PaMYD8stfukfCbXjoY5pD5FIpj1Os7dDtgdoygp0tfsA4mDg1O0exZoduR9s q4NNPlsnlKOjX2KMOdcWI2AR8/xiFi4zvDTB/vibQPMy8kXVB8ld4Mk0BF1TUyOv 80KKOKzFDxQeLzvoEiNm6FDAqYGEYmpECUaFGXyKG1a7wslhEmEeShJUH5lsj3Oz niMxoO/KTEW0U9QucHQogFJzrcsKkJiOByjqQovWKgZziJll38lCN0O1murMmRBC bDLmN9t53JC7Ef88AbKsaFeULy/AxriohdGU6ePb8j/4W9KlERSJyvgxFkcMxHTg 9mSPiYAHaPr+Ycrzs9SOqhki5b6tI8Q39W/etRorb2us9FS1JE7ib4XLk5ufiUje XOLc4TACUh1qnd/5UUgcIuUrg/akSJgJLZoXg36LqUF/1OeMJHec4RMJresvewAZ RwseWHH/KpD7KxOWlO2Zw1ceHlVFDLWOO/4KWoy/XwZ66fQxEAkLO8ZVyeKMh5Nh dYL+yLQKZdgNWAjalK4lFmwz3u/9jNITwtP5GYLbYnP28EcbDfiN/w9oKGOI8fsD ulD+ca3vx29qdmGGYcKt =9+bG -----END PGP SIGNATURE-----

sieve: is it possible to filter ALL mailing lists (with header List-Id) to their folders with ONE rule?
by Lev Serebryakov 15 Sep '14

15 Sep '14

Hello, Dovecot. Is it possible to write one rule in sieve, which will: (1) Trigger on any message with "List-Id" header AND (2) Put this message to folder with name build from content of "List-Id" header, in such way, that message with List-Id List-Id: This is decription of list <list-name.host.org> will be put into folder "org.host.list-name" where "." is namespace separator (so, such folders will be shown as hierarchy in mail client)? I don't want to write ~50 rules by hands and add new ones from time to time. I'm speaking about dovecot/pigeonhole sieve implementation, of course. All examples on net shows only manual one-rule-per-list approach :( -- // Black Lion AKA Lev Serebryakov <lev(a)serebryakov.spb.ru>

Migration - Getting it right the first time.
by Dan Carroll 15 Sep '14

15 Sep '14

Hello All, I’m currently in the process of migrating a very old imap installation to a new server. I think I have everything in place now but I’ve not yet written the procedure on how to do it. The outline will be as follows: put MTA-OLD into store mode where it holds the incoming emails for an indefinite period. Copy all IMAP data across to the new server. Process the IMAP data, converting it from courier to dovecot. put MTA-OLD into forward mode, sending all mail to MTA-NEW Adjust MX records accordingly so MTA-OLD is no longer used. The “process” part is where I need to take some care. I am aware of the migration tool available for moving the data, but I’m not confidant that my courier databases are in a healthy state. Does anyone have any idea how I can verify that this is the case? I’m happy to do it either before, or after the migration to dovecot, but I’d probably prefer to do it beforehand on the old server. The biggest thing I am concerned about is losing the order of mail messages. It’s not always enough to trust the “received date” for sorting mail, I’d rather my imap clients trust the imap server to send them the correct order. A second question. Is there a possibility to make the MTA switch, and migrate the messages across in an orderly fashion at a later date? Again, I’d like to ensure that older migrated messages appear further down the “order” than new messages coming into the MTA. Lastly, thanks for an awesome piece of software. My limited experience so far has been refreshing! -Dan

Dovecot HA
by Hoggins! 12 Sep '14

12 Sep '14

Hello everyone, Following my previous message about replication (I'm still stuck), I was wondering in a more general way how to achieve high availability with Dovecot, and how to store the mail data. Do you have some thoughts about this ? Maybe one or two links leading to people who already have ideas or experience ? I don't host a big e-mail service, nor have a lot of clients connecting. I just need to ensure that data is always available, from the storage to the actual service. Thanks in advance.

charset-specific searches, and continuation lines
by Eric Abrahamsen 12 Sep '14

12 Sep '14

Hi there, I'm looking into improving IMAP search support for the Gnus Emacs mail client, and trying to add the ability to search non-ascii characters. So far as I know, I start this invocation with something like: . UID SEARCH CHARSET UTF-8 TEXT {NNN} Where NNN is the number of bytes in my search string. Dovecot then responds with: + OK So... what do I do then? I don't actually know what the next statement is, to provide the actual search string itself. Googling has proved unhelpful, as most of the examples online don't actually show this "+ OK" response. Can someone just briefly outline what's meant to happen next? I've tried including the search string immediately after the byte-size, separated by various combinations of \n\r, but that always gives me a "Missing LF after literal size" error. I'm using the Archlinux dovecot package, which reports version 2.2.13-1. Thanks! Eric

Problem with virtual folders
by Urban Loesch 11 Sep '14

11 Sep '14

Hi, I'm trying to activate some virtual folders on a new installed dovecot server. My plan is to have two virtual folders like "All" and perhaps "Unseen", like Gmail style for the first step. - All: lists me all messages in the users mailbox - Unseen: all unseen messages in the users mailbox I'm using dovecot EE Release: ii dovecot-ee-core 1:2.2.13.8-1 amd64 secure mail server that supports mbox, maildir, dbox and mdbox mailboxes ii dovecot-ee-imapd 1:2.2.13.8-1 amd64 secure IMAP server that supports mbox, maildir, dbox and mdbox mailboxes ii dovecot-ee-lmtpd 1:2.2.13.8-1 amd64 secure LMTP server for Dovecot ii dovecot-ee-managesieved 0.4.3-1 amd64 secure ManageSieve server for Dovecot ii dovecot-ee-mysql 1:2.2.13.8-1 amd64 MySQL support for Dovecot ii dovecot-ee-sieve 0.4.3-1 amd64 sieve filters support for Dovecot But I can't get it to work. I can see the virtual folders in my Thunderbird, but the folders are empty and can't find any errors in mail log. I also tried it with "mail_debug = yes".

I copied the configuration from this server. The only three differences between the two servers are: - Server version is different. - The prefix of the default namespace on the new server is "prefix = INBOX/" and not "prefix =" - Mail storage and index files are seperated in different folders on the new server. Here are the relveant namespace configuraiton from the server where it ist working fine: ... namespace { list = children location = mdbox:/home/vmail/%%d/%%n prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace { hidden = no inbox = no list = children location = virtual:/home/virtual:INDEX=~/virtual prefix = [rolmail]/ separator = / subscriptions = yes type = private } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Items" { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = separator = / type = private } ... Have you any hint for me how I can fix my problem. Thanks and regards Urban Loesch

minimal configuration for lucene fts
by Eric Abrahamsen 11 Sep '14

11 Sep '14

Hi, I'm using dovecot (version 2.2.13 on archlinux) in the simplest, no-brainer way possible. It sits between mbsync, which I use to fetch mail from servers, and Gnus, my MUA. Both mbsync and Gnus connect to dovecot with an invocation like this: /usr/lib/dovecot/imap -o mail_location=maildir:$HOME/.mail/ea/ I have three different mail accounts, all that changes is the final directory on the mail_location path above. I haven't touched anything else: there's no running daemon, no configuration, no user database, no PAM, no nothing. Now I'm trying to set up text searching via lucene, but all the examples I've seen online assume a full running daemon and user accounts. I tried to fake it by running: doveadm index -u eric@localhost -q INBOX -o mail_location-maildir:/home/eric/.mail/ea but it was clearly expecting a user database. Is there any way to create text indexes for my three different accounts, in their respective directories, without fully setting up a running dovecot? I'll do that if I have to, but my current setup works great, and is very simple, and I'd like to keep it simple if I can. Thanks! Eric

Just a wild-ass guess, but shouldn't "master_user=%u" be something like "master_user=muser" where "muser" is the master user as defined in your master password file?

outlook 2013
by Bob Miller 10 Sep '14

10 Sep '14

I am trying really hard to wrap my head around why people insist on using this program... Where I have outlook 2013 users, I have had nothing but problems getting their mail to work with imap. my solution has been to set them up with pop, which works just like it always has. Or move them to a different program. recently, I have a customer who requires multiple machines, all using outlook 2013, to access the same email address, so pretty much have to use imap. if I set up just one of the machines with imap, it works more less as expected, with hiccups such as mail taking an hour or two or more to show up. But shortly after I connect a 2nd machine to the same account, one or both machines start to go wonky. Symptoms include deleted items returning, read messages becoming unread again, and duplicates being constantly created and deleted. The last I can confirm by watching in webmail and refreshing the inbox every few seconds; as mail shows up and deletes in outlook, so it does in webmail too. On my test machine connected to the same server, I have evolution, outlook and thunderbird all connecting to one account with no problems. Well, outlook hiccups, but it's not unusable. And I have other users on the system that share email accounts across a variety of other clients and platforms, including older versions of outlook. I have tried checking message rules, there are none; removing all folder subscriptions; running scanpst, which finds errors even before the account finishes syncing and ever time I run it after that; I have looked for viruses/malware; I have confirmed there is no forwarding or some trickery happening on the server; chkdsk and similar hardware checks all come up clean, the computers are only a couple of months old; I have got certs set up with SANs and the CA installed such that outlook does not error on the certificate; and I have tried just about every combination of settings that seem relevant. The one thing that does seem to work, at least for a few minutes or an hour or two, is deleting and recreating the accounts on one of the computers. But the problem inevitably returns in short order. Surely people have outlook 2013 connecting via imap to dovecot without problems; is there some special trick that google is hiding from me? -- Computerisms Bob Miller 867-334-7117 / 867-633-3760 http://computerisms.ca

Dovecot replication
by Hoggins! 10 Sep '14

10 Sep '14

Hello list, I'm trying to achieve very simple replication, but I'm not sure if I'm starting the good way. I have two Dovecot servers that use the same GlusterFS storage. Of course, the indexes get corrupted eventually, even if I apply an "NFS-like" configuration. So I'd like to synchronize my two servers with each other. I'm trying to follow this page : http://wiki2.dovecot.org/Replication, but I have to admit that it's not really self-explanatory. I got several errors, so I decided to start fresh, and that is why I'm not giving you any configuration, but I prefer asking if I have the prerequisites. The page states that my userdb should have "user listing", and that you can check it by issuing `doveadm user '*'`. But I don't know what it's supposed to produce, apart from my userlist (my userdb is the system passwd file). As my servers are located on the same private LAN, I decided I would not go with the SSH replication solution, but with the simple mutual TCP connection... Maybe this is a wrong start. Any help will be appreciated. Thanks in advance !

dovecot 2.2.13: LMTP delivery with multiple recipients incorrectly mixes users
by Arkadiusz Miśkiewicz 10 Sep '14

10 Sep '14

Hi. I'm using exim that delivers email over LMTP to dovecot 2.2.13. I noticed that dovecot LMTP service is sometimes (reare but repeats) mixing users. Example below. There is one mail (msgid=<1ACE53B70631CA45B62348E4EE8757493731A59E@KRMXA41>) that is going to be delivered to multiple local recipients. Some recipients are delivered properly: Sep 1 05:40:33 host dovecot: lmtp(3176): Connect from local Sep 1 05:40:34 host dovecot: lmtp(3176, gbuser1): TDO+HNDpA1RoDAAA16XVAg: msgid=<1ACE53B70631CA45B62348E4EE8757493731A59E@KRMXA41>: saved mail to INBOX Sep 1 05:40:34 host dovecot: lmtp(3176, jpuser2): TDO+HNDpA1RoDAAA16XVAg: msgid=<1ACE53B70631CA45B62348E4EE8757493731A59E@KRMXA41>: saved mail to INBOX Sep 1 05:40:34 host dovecot: lmtp(3176, rkuser3): TDO+HNDpA1RoDAAA16XVAg: msgid=<1ACE53B70631CA45B62348E4EE8757493731A59E@KRMXA41>: saved mail to INBOX Sep 1 05:40:34 host dovecot: lmtp(3176, gbruser4): TDO+HNDpA1RoDAAA16XVAg: msgid=<1ACE53B70631CA45B62348E4EE8757493731A59E@KRMXA41>: saved mail to INBOX Sep 1 05:40:34 host dovecot: lmtp(3176, pbauser5): TDO+HNDpA1RoDAAA16XVAg: msgid=<1ACE53B70631CA45B62348E4EE8757493731A59E@KRMXA41>: saved mail to INBOX Sep 1 05:40:34 host dovecot: lmtp(3176, mwauser6): TDO+HNDpA1RoDAAA16XVAg: msgid=<1ACE53B70631CA45B62348E4EE8757493731A59E@KRMXA41>: saved mail to INBOX Sep 1 05:40:34 host dovecot: lmtp(3176, mdyuser7): TDO+HNDpA1RoDAAA16XVAg: msgid=<1ACE53B70631CA45B62348E4EE8757493731A59E@KRMXA41>: saved mail to INBOX but some are not: Sep 1 05:40:34 host dovecot: lmtp(3176, lkrzyuser8): Error: lstat(/var/lib/dovecot/control/gbuser1/.INBOX/dovecot-uidlist.lock) failed: Permission denied Sep 1 05:40:34 host dovecot: lmtp(3176, lkrzyuser8): Error: file_dotlock_create(/var/lib/dovecot/control/gbuser1/.INBOX/dovecot-uidlist) failed: Permission denied (euid=28371(<unknown>) egid=17373(<unknown>) missing +x perm: /var/lib/dovecot/control/gbuser1, dir owned by 67593:17373 mode=0700) Notice it was trying to deliver to user "lkrzyuser8" but it tries to access some other user files (dovecot-uidlist). euid=28371 is indeed "lkrzyuser8" but why it tries to access "gbuser1" files?

Replication problem
by Ve (HOME) 10 Sep '14

10 Sep '14

Hi, I'm using mdbox and replication. Due to configuration error synchronization was not able to be done last week. Since then the problem has been corrected but synchronisation for some mailbox always failed in I/O stalled timeout for 600 seconds. The link between the two servers is quite slow and multiple sync are done in parallel leading to congested link. I can't replicate with rsync as change in the mdbox has been done on the two servers to get back to a working state. What do you think could be done to resynchronized the two dovecot server. Another question is what is this timeout ? Timeout of communication i.e no data received during 600 seconds ( to me that looks unlikely ) or 600 seconds for doing the full sync or 600 seconds for one mail sync. Thanks for any help. Regards, Vincent

preserving flags for shared mailbox when migrating from cyrus to dovecot
by Jogi Hofmüller 10 Sep '14

10 Sep '14

Dear all, Despite all the progress we are making in our attempt to make the migration as smooth and transparent for our users there are still some important unsolved issues. One thing that I can't figure out is how to preserve a user's flags that s/he has for mail in a shared mailbox. So far we tried 'doveadm backup -R' as well as the cyrus2dovecot script from here [1]. Both work well for individual mailboxes but do not migrate subscriptions for shared mailboxes and -- more importantly -- flags for mail in a shared mailbox. Reconstructing subscriptions is quite easy but I have no clue on how to reconstruct a user's flags. Any hint is greatly appreciated!

master user in ldap?
by Francesco 10 Sep '14

10 Sep '14

Hello everyone, i was wondering if it was possible to add master user criteria in ldap backends. the idea is that the users, members of a specific group, should be able to login with their own credentials on behalf of other users. i've tried setting it up like this: hosts = localhost dn = CN=ldapuser,OU=someldapou,DC=domain,DC=tld dnpass = <password> auth_bind = yes ldap_version = 3 base = DC=domain,DC=tld user_attrs = sAMAccountName=home=/var/vmail/% $,skip=found,maxStorage=quota_rule=*:storage=% $M,quota_rule2=Trash:storage=+100M user_filter = (&(ObjectClass=person)(sAMAccountName=% u)(memberOf=CN=Domain Admins,CN=Users,DC=domain,DC=tld)) then i added a passdb as follows passdb { driver = ldap master = yes args = /etc/dovecot/dovecot-ldap-masteruser.conf.ext } and of course the separator. but when i try to login with realuser*userinadministratorsgroup passwordofuserinadministratorsgroup i get authentication failed. am i missing something? is it even possible to accomplish such thing? because i didn't see any example in the wiki, only plain passdb and sql. thanks in advance Francesco

Escape comma in the LDAP passdb subquery configuration
by Francesco Fiore 10 Sep '14

10 Sep '14

Hi I have to configure the LDAP passdb to execute a subquery defining dinamically the new DN to use. For example: pass_attrs = @mail=mail=%{login_user},dc=%{login_domain},dc=example,dc=com,\ =proxy=y,\ =host=%{ldap:mailHost@mail} In the previous example, the problem is the use of "," for DN representation, which is also the separator for the attribute template in the pass_attr parameter value. I tried to escape it with '\' or '%' but it doesn't work. Dovecot version is 2.2.13. How can I resolve this issue? Thanks in advance

ACL with Public Namespace
by Bruno Galindro da Costa 09 Sep '14

09 Sep '14

I've configured a namespace like this: namespace avisos { type = public list = yes location = maildir:/var/mail.avisos:INDEXPVT=~/Maildir/avisos subscriptions = yes prefix = "AVISOS." mailbox DIVULGA { auto = subscribe } } This is the namespace representation in filesystem: root@imap:~# ls -lha /var/mail.avisos/ total 44K drwxr-xr-x 7 vmail mail 4,0K Set 9 18:21 . drwxr-xr-x 16 root root 4,0K Set 9 17:08 .. drwxr-xr-x 5 vmail mail 4,0K Set 9 16:49 .DIVULGA -rw-r--r-- 1 root root 17 Set 9 18:21 dovecot-acl -rw-r--r-- 1 vmail mail 0 Set 9 18:11 dovecot-acl-list -rw-r--r-- 1 vmail mail 360 Set 9 18:11 dovecot.mailbox.log -rw-r--r-- 1 vmail mail 8 Set 9 18:02 dovecot-uidvalidity -r--r--r-- 1 vmail mail 0 Set 9 14:57 dovecot-uidvalidity.540f3f88 -rw-r--r-- 1 vmail mail 249 Set 9 18:11 subscriptions This is the content of dovecot-acl file located at namespace's root level: root@imap:~# cat /var/mail.avisos/dovecot-acl authenticated rs After reload dovecot service, it trows this error message in log: Sep 9 18:14:13 imap dovecot: imap(user@mydomain): Error: Failed to autocreate mailbox AVISOS.DIVULGA: Permission denied So, I've changed the dovecot-acl file to this one and the problem was solved. root@imap:~# cat /var/mail.avisos/dovecot-acl authenticated rsk But that change created another problem: dovecot-acl file is copied into AVISOS.DIVULGA. So, the user can create a maildir inside it. This behaviour is bad because "invalid" maildirs are created under the filesystem. My intention is to don't permit the user to create any maildir inside any location of that namespace. But, I want to make possible to the administrator to edit the dovecot.conf, insert a new mailbox into namespace avisos and reload dovecot service to create new maildirs automatically. How can I solve this problem? -- Att. Bruno Galindro da Costa

Dovecot + Postfix postmulti SASL
by Nerijus Kislauskas 09 Sep '14

09 Sep '14

Hello, Our Postfix setup uses multi-instance feature. I would like to enable dovecot SASL mechanisms in postfix. Open two unix sockets is not a problem for us: service auth { unix_listener /var/spool/postfix-instance1/private/auth { mode = 0660 user = postfix group = postfix } unix_listener /var/spool/postfix-instance2/private/auth { mode = 0660 user = postfix group = postfix } } Lets assume, that postfix-instance1 uses LDAP1, and postfix-instance2 uses LDAP2. How can I use different userdb and passdb databases for those sockets? -- Sincerely, Nerijus Kislauskas

Panic/backtrace in dovecot 2.2.13
by Ed W 07 Sep '14

07 Sep '14

Hi I'm running into regular problems with dovecot choking on "corrupted" index files. The main problem is that it doesn't sort itself out and recover. This message below is repeated regularly in the log files (until I delete the index files) I *think* the trigger to get into this situation might be a files being delivered with incorrect S= values in the filename? Which is to say I am using maildrop to deliver messages and occasionally maildrop seems to write files with incorrect S= names (anyone know why or how to fix it?). The error logged regarding incorrect S= values is obviously completely different, but I speculate that it could be the earlier cause that gets the index file out of shape as shown in the problem here Thanks for any help?

lmtp memory usage problem - Fatal: pool_system_realloc(268435456): Out of memory
by Arkadiusz Miśkiewicz 05 Sep '14

05 Sep '14

Hi. In my setup exim delivers mails to dovecot using LMTP. In one LMTP session exim can deliver up to 200 recipients (batch_max set to that value). Now the problem is that sometimes 256MB is not enoug for dovecot lmtp to handle incoming emails. My questions: - how big memory limit should be for lmtp? I was thinking that lmtp (more or less) simply reads from one descriptor and writes to file, then does rename() (maildir used here) and that's all. That shouldn't require big number of memory. So how to determine correct memory limit and what affects this limit? - is number of recipients in one LMTP session important here? Not sure, maybe dovecot stores email in memory first and then writes to the user maildirs? Setting (batch) limit to 1 could reduce memory usage then (since no need to store anything in memory) ? Thanks, Log: Sep 4 16:10:30 mail dovecot: lmtp(21383, user): Fatal: pool_system_realloc(268435456): Out of memory Sep 4 16:10:30 mail dovecot: lmtp(21383, user): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(+0x682a0) [0x7fe327e632a0] -> /usr/lib64/dovecot/libd ovecot.so.0(+0x6837e) [0x7fe327e6337e] -> /usr/lib64/dovecot/libdovecot.so.0(i_error+0) [0x7fe327e1dbf8] -> /usr/lib64/dovecot/libdovecot.so.0(+0x7d6a3) [0x7fe327e786a3] -> /usr/lib64/dovecot/libdovecot.so.0(i_stream_grow_buffer+0x8f) [0x7fe327e6c4cf] -> /usr/lib64/dovecot/libdovecot.so.0(i_stream_try_alloc+0x82) [0x7fe327e6c592] -> /usr/lib6 4/dovecot/libdovecot.so.0(+0x73b9b) [0x7fe327e6eb9b] -> /usr/lib64/dovecot/libdovecot.so.0(+0x73c36) [0x7fe327e6ec36] -> /usr/lib64/dovecot/libdovecot.so.0(i_stream_read+0x 53) [0x7fe327e6bad3] -> /usr/lib64/dovecot/libdovecot.so.0(+0x77391) [0x7fe327e72391] -> /usr/lib64/dovecot/libdovecot.so.0(i_stream_read+0x53) [0x7fe327e6bad3] -> /usr/lib 64/dovecot/libdovecot.so.0(i_stream_read_data+0x3d) [0x7fe327e6c2fd] -> /usr/lib64/dovecot/libdovecot.so.0(io_stream_copy+0x7f) [0x7fe327e7cacf] -> /usr/lib64/dovecot/libdo vecot.so.0(+0x83310) [0x7fe327e7e310] -> /usr/lib64/dovecot/libdovecot.so.0(o_stream_send_istream+0x4d) [0x7fe327e7c92d] -> /usr/lib64/dovecot/libdovecot-storage.so.0(maild ir_save_continue+0x5a) [0x7fe32811b14a] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mail_storage_copy+0x88) [0x7fe328145328] -> /usr/lib64/dovecot/libdovecot-storage.so.0 (maildir_copy+0x42) [0x7fe3281179c2] -> /usr/lib64/dovecot/plugins/lib10_quota_plugin.so(+0xb52b) [0x7fe32764352b] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mailbox_cop y+0x6d) [0x7fe32814d29d] -> /usr/lib64/dovecot/libdovecot-lda.so.0(mail_deliver_save+0x185) [0x7fe3283f1765] -> /usr/lib64/dovecot/libdovecot-lda.so.0(mail_deliver+0xeb) [0 x7fe3283f1b6b] -> dovecot/lmtp() [0x405d80] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_call_io+0x3f) [0x7fe327e7398f] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handl er_run_internal+0xd7) [0x7fe327e74897] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x9) [0x7fe327e739f9] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x3 8) [0x7fe327e73a78] -> /usr/lib64/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7fe327e22ca3] Sep 4 16:10:30 mail dovecot: lmtp(21383, user): Fatal: master: service(lmtp): child 21383 returned error 83 (Out of memory (service lmtp { vsz_limit=256 MB }, you may need to increase it) - set CORE_OUTOFMEM=1 environment to get core dump) -- Arkadiusz Miśkiewicz, arekm / maven.pl

stemmer or no-stemmer..
by Akash 05 Sep '14

05 Sep '14

Hi, In the documentation of FTS lucene, I need little more clarification about this section: -------------------------------------------------- --with-lucene --with-stemmer The second switch is only required if you have compiled libstemmer yourself or if it's included in the CLucene you are using. -------------------------------------------------- I am totally unsure but as I understand, on Debian testing, the stemmer support for libclucene comes as part of libclucene-contribs1 package (which isn't a required dependency and doesn't get installed if I install dovecot from repos). Please correct me if I am wrong. When I install dovecot-lucene from repos, libclucene-core1 and libstemmer install with it (but no libclucene-contribs1). Does that mean dovecot search has stemmer support? Now I am compiling dovecot and libclucene for Debian stable (which doesn't have latest libs in repos). If I don't compile the contribs part in clucene package but compile dovecot with --with-stemmer, do I get the stemmer support? If I totally opt of this stemmer thing, do I lose anything on search performance? And when you have a no_snowball option, what is the need of libstemmer altogether? Please help me through these confusions.. -Regards, Akash

Migrating from 2.0.x to 2.2
by Jens Dueholm Christensen 05 Sep '14

05 Sep '14

Hi I'm about to migrate a setup with <20 IMAP (but with a few million mails in all) accounts that belong to the same system-user on an older machine running Dovecot 2.0.13 to a new machine running Dovecot 2.2.13 (or possibly newer..). Mails are stored in Maildirs with no special or advanced features (like alternate storage etc etc). Filesystems are prepared for the expected amount of inodes required, and for the time beeing a change to mdbox is seen as an added complexity. One requirement of the migration is that messageID is not changed - mails are referenced by other systems that expect to find individual mails by the ID. Since dsync is incompatible between 2.0<->2.1<->2.2 what is the best way to perform this migration? I was hoping of rsync'ing all Maildirs from the old machine to the new one (including indexes etc etc) and power up Dovecot 2.2.x and see what happens, but is that possible or is there another (and better) way short of installing 2.0.x on the new machine, rsync everything and then upgrade to 2.2.x? Regards, Jens Dueholm Christensen

Hi, I want to profile runtime performance of imap and pop3 processes. There processes are forked by dovecot master process. I am wondering if there is a way I can profile these processes with valgrind. I tried "service = /bin/valgrind /bin/imap" but this did not work. Thanks,

Hi All, I have a problem with SASL authentification from postfix when more than 10 mails is sent from the same user simultaneously Postfix abort connection ( Connection lost to authentication server ).

Trying Dovecot Replication with dsync
by Listas＠Adminlinux 04 Sep '14

04 Sep '14

Hi, I have a failover cluster for mail server with: Ubuntu12.04 + DRBD (for block replication) + Ext4 filesystem + Dovecot-2.0.19-2 with Mdbox It works fine with ~50k accounts. My cluster design: http://adminlinux.com.br/cluster_design.txt I plan to test Dovecot Replication with dsync to build an active/active cluster with load balancing. Can anyone direct me to some literature? A tutorial for example. I'm installing a cluster (for tests) with Ubuntu 14.04 + Ext4 filesystem (without Drbd) + Dovecot-2.2.9-1ubuntu2.1. My conf is in: http://adminlinux.com.br/replication-doveconf.txt I'm following this doc http://wiki2.dovecot.org/Replication but I'm getting some errors: 1) Aug 14 15:39:34 ceph1 dovecot: imap(account=domaintest.com): Error: open(/var/run/dovecot/replication-notify-fifo) failed: Permission denied What is the correct perms for /var/run/dovecot/replication-notify-fifo ?

Is it possible to log a message custom header through Mail logger plugin or other method? It seems that there are a fixed number of info that is configurable via mail_log_fields (http://wiki2.dovecot.org/Plugins/MailLog) .. My custom header is X-VERTICAL-IP-Quarantine-ID and I want a log event like this one: Aug 27 09:48:13 imap dovecot: imap(user@domain): copy from INBOX: box=SPAM, uid=213, *X-VERTICAL-IP-Quarantine-ID=u7cnUqYDPA9a*, msgid=< 0.0.D7.290.1CFC155CE887302.0(a)etm2.com>, size=26481, vsize=26949, from==?UTF-8?Q?Dafiti=20-=20Parceiros?= <aaa@domain>, subject==?UTF-8?Q?Sapatos=20com=2040%OFF?==?UTF-8?Q?!=20Apro?=? =?UTF-8?Q?veite!?= -- Att.

Setup sieve failed
by Christian Vielhauer 03 Sep '14

03 Sep '14

Hi, I try to setup sieve but I have some trouble. Using dovecot 2.2.9 on Ubuntu 14.04.1 LTS. I replaced my correct domain with „domain.tld“. I am able to create sieve scripts using SOGo. The scripts are created in my mailbox. For example in /var/www/kunden/mail/domain.tld/testuser/sieve/sogo.sieve I have the following script and in same ~/sieve folder is a subdirectory available that’s called "tmp“: ~/sieve ~/sieve/tmp require ["vacation"]; if allof ( not exists ["list-help", "list-unsubscribe", "list-subscribe", "list-owner", "list-post", "list-archive", "list-id", "Mailing-List"], not header :comparator "i;ascii-casemap" :is "Precedence" ["list", "bulk", "junk"], not header :comparator "i;ascii-casemap" :matches "To" "Multiple recipients of*" ) {vacation :days 1 :addresses [„testuser(a)domain.tld"] text: This is a vacation test message.

quota for subfolder with prefix=INBOX.
by Jogi Hofmüller 03 Sep '14

03 Sep '14

Hi all, We use prefix=INBOX. in order to keep things as they were on the old server. Now I started playing with quota and have trouble getting the additional quota for Trash and/or Junk working. My expectation was that once a user is over quota and moves email to trash sh/e should be able to receive new email again. That's what I cannot get to work with our setup. Attached you find the config that I thought should be working. The numbers are ridiculously low but that's just for testing. Here is some output from doveadm doveadm quota get -u user Quota name Type Value Limit % User quota STORAGE 5422 5120 105 User quota MESSAGE 18 - 0 doveadm mailbox status -u user "messages vsize" "*" INBOX messages=13 vsize=3147033 doveadm mailbox status -u user "messages vsize" "INBOX.*" INBOX.Drafts messages=0 vsize=0 INBOX.Sent messages=0 vsize=0 INBOX.Trash messages=5 vsize=2475790 INBOX.Junk messages=0 vsize=0 Regards, -- j.hofmüller We are all idiots with deadlines. - Mike West

Trouble viewing Inbox via IMAP Client

dsync-server couldn't create .dovecot-sync.lock file

My dovecot stores users' emails on /var/spool/imap/<user> and stores the messages index on /var/lib/imap/<user>.

mail_location hashing & lowercasing?
by Ralf Hildebrandt 31 Aug '14

31 Aug '14

Currently, I'm using mail_location = mdbox:/var/spool/mail/%Ld/%Ln/mdbox Now I want to add a partitioning (so I don'T have all directories in one single directory), but can't find the right syntax: mail_location = mdbox:/var/spool/mail/%Ld/<HASHING HERE>/%Ln/mdbox It seems like I'd need to use %N (new hash) on %Ln and then take a substring of that. %2NLn 2 Characters of the %N hash of %Ln (the lowercase username) But this gives me a verbatim "Ln" on the path! -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein

Need help to compile and install a minimal dovecot imap plugin
by Stefan Arentz 31 Aug '14

31 Aug '14

I am trying to create a plugin that adds a new IMAP capability. So far I have this: const char *foo_plugin_version = DOVECOT_ABI_VERSION; static struct module *foo_module; static imap_client_created_func_t *next_hook_client_created; static void foo_client_created(struct client **client) { str_append((*client)->capability_string, " XFOO"); if (next_hook_client_created != NULL) { next_hook_client_created(client); } } void foo_plugin_init(struct module *module) { i_info(“init”); foo_module = module; next_hook_client_created = imap_client_created_hook_set(foo_client_created); } void foo_plugin_deinit(void) { i_info(“deinit”); imap_client_created_hook_set(next_hook_client_created); } const char foo_plugin_binary_dependency[] = "imap”; On Fedora 20, with the dovecot and dovecot-devel packages installed, I compile this with: cc -Wall -shared -fPIC -DHAVE_CONFIG_H -I/usr/include/dovecot -o lib20_foo_plugin.so foo-plugin.c And then install with: sudo cp lib20_foo_plugin.so /usr/lib64/dovecot/ (I also have mail_plugin_dir = /usr/lib64/dovecot in 10-mail.conf) I enable this plugin in /etc/dovecot/conf.d/20-imap.conf with: protocol imap { mail_plugins = $mail_plugins foo } But … nothing happens. No warnings, no errors, no crashes. How do I debug this? Am I missing something obvious? Does the naming of the plugin matter? S.

Misleading error message when case-insensitive file/dir names from config files clash with case-sensitive file system.
by Info Akra 30 Aug '14

30 Aug '14

Hi, Is it noted somewhere that Dovecot (v 2.0.9) doesn’t use case in directory names in its config-files? I found that out the hard way (i.e. a week of debugging)!! in /etc/dovecot/conf.d/10-master.conf, the line: unix_listener /var/spool/postOut/auth/dovecot-auth { creates a: Jul 29 22:15:58 server dovecot: master: Error: service(auth): unlink(/var/run/dovecot/) failed: Is a directory but unix_listener /var/spool/postout/auth/dovecot-auth { works just fine (with matching case changes on the directory names themselves). That’s on running on Ubuntu 12.04.4 TLS, standard installation from apt-get, in cooperation with Postfix 2.0.9. — Hugo

Dsync setup... help needed
by Sinergizmas Sin ergizmas 30 Aug '14

30 Aug '14

Hello, I tried to implement Dsync (doveadm version 2.2.10) following https://www.evilcoder.org/2014/08/22/automatic-replication-with-dovecot/ but had no luck. SSH commands working quite well, but I need to respond more quickly. So TCP looks promising. I have Centos 6, Dovecot 2.2.10. I did everything that is written there, but after I restart dovecot doesn't sync. Then i ran netstat command but no service listen to port 12345 also. Iptables service are of in testing scenario...

Migrating courier to dovecot
by Patrick Lion 29 Aug '14

29 Aug '14

Hi, i want to migrate the following setup: postfix / courier-{imap/s,pop3/s,authlib} / maildrop / mysql I´m using the maildir format and quotas as well. My target is the following setup: postfix / dovecot / some sort of quota respecting lda / mysql What i`ve done already: SQL-Implementation for dovecot, login process and also sending mails via auth-userdb is already working. Quotas are read out from database and working. Before i mention my problems while implementing, here is the config im using at this time: # 2.2.13: /etc/dovecot/dovecot.conf # OS: Linux 3.14.14-gentoo x86_64 Gentoo Base System release 2.2 auth_mechanisms = plain login auth_socket_path = /var/run/dovecot/auth-userdb auth_verbose = yes disable_plaintext_auth = no info_log_path = syslog login_log_format_elements = user=<%u> method=%m ip=%r mpid=%e mail_debug = yes mail_location = maildir:.maildir mail_plugins = quota namespace inbox { inbox = yes location = .maildir 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 = INBOX. separator = . } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { args = /etc/dovecot/dovecot-sql.conf.ext quota = maildir:User quota quota_rule = %u quota_rule2 = trash:storage=+150M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u } service auth { unix_listener /var/spool/postfix/private/auth { group = mail mode = 0660 user = postfix } unix_listener auth-userdb { group = mail mode = 0660 user = postfix } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0666 user = postfix } } ssl_cert = </etc/ssl/dovecot/server.pem ssl_key = </etc/ssl/dovecot/server.key userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota } grep -v '^ *$#.*$\?$' dovecot-sql.conf.ext driver = mysql connect = host=127.0.0.1 dbname=postfix user=postfix password=thereisone default_pass_scheme = MD5-CRYPT password_query = \ SELECT username, password \ FROM mailbox WHERE username = '%u' user_query = \ SELECT concat('/', home, user, '/', destinationname) AS home, uid, gid, \ concat('*:storage=', round(quota / 1000 * 1.024)) AS quota_rule \ FROM mailbox WHERE username = '%u' Where user is the row where the admin-panel user is stored and username is the mbox-user. My problem is the LDA, with dovecot-lda im having the uid / gid trouble and i really dont want to suid oder sudo it. dovecot-lmtp just gives me status=deferred (host xx.xx[/var/run/dovecot/lmtp] said: 451 4.3.0 <box(a)xx.xx> Temporary internal error (in reply to end of DATA command)) Postfix virtual is working as well as maildrop, but no dovecot-implementation wants to, i also didnt find anything about the error above, except a bug in v2.2.2 and a google groups thread where users are just blaming each others for nothing .. I want to use a dovecot lda/lmtp because the quota settings for trash-folders are very nice and reducing my support times but im stuck at getting one of the dovecot-LDAs to work. Let me know if you need any additional information. Any help is greatly appreciated! -- Viele Grüße / Best regards Patrick

Multiple A Records for IMAP service
by Vijay Rajah 29 Aug '14

29 Aug '14

Hello All, I have a quick question. I have 2 MX servers each with a Dovecot Instances (2.2.6). These 2 Dovecot Instances are replicated by using Dsync... All works well. The questions is, Can I have 2 A records for my imap.mydomain.tld? The Idea being, if for any reason, one of the Dovecot IMAP instances are unreachable, the client can connect to the other Instance. (this is purely a fail over scenario). If it matters, The clients are Thunderbird, Android Native (default) Mail client, iOS Mail Client. -Thanks in advance Vijay

Documentation for /usr/lib/dovecot/imap executable
by Christoph Groth 29 Aug '14

29 Aug '14

Dear Dovecot experts, I'm in the process of setting up dovecot with mbsync as a local cache for remote IMAP servers. One recipe that I found involves using the /usr/lib/dovecot/imap (This is with Debian's dovecot package). For example, in .mbsyncrc I have IMAPAccount cwg-wf-local RequireSSL no Tunnel "/usr/lib/dovecot/imap -o mail_location=maildir:/home/cwg/.mail/cwg-wf" This works, but I wonder: is there any documentation for the /usr/lib/dovecot/imap executable? What options does it take? If there's no documentation: where can I find this command in dovecot's sources? Thank you, Christoph

Postfix + dovecot setup
by Timothy Murphy 29 Aug '14

29 Aug '14

I'm trying to clarify the various ways in which I could set up Postfix + Dovecot + SpamAssassin under CentOS-7, and I'd welcome any comments on the following remarks. As far as I can see there are 3 standard ways of setting this up: 1. Use amavisd 2. Use dovecot + pigeonhole/sieve 3. Use spamass-milter At present I'm following (2), but am thinking of going over to (1), since this seems simpler. (Amavisd wasn't available when I set up CentOS-7, so I didn't consider it then.) It seems to me that (2) is using dovecot in a slightly odd way, since as far as I can see dovecot normally takes email from ~/Maildir/cur/ and then moves marked spam. I'm not quite sure if (3) is a genuine alternative, or if it is why it is not the standard? -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

Hi all! Does dovecot cluster (with Proxy/Director) work only distributed filesystems (like NFS) ? Is Dovecot-replication + Ext4 recommended for production environments? Thanks! -- Thiago Henrique

Hi, I'm trying to use imapsync to migrate my accounts and mailbox (mbox) of an server A (Postfix + Dovecot) to a Server B (Zimbra), without having to change user passwords on the server A, using a master user account. I'm using this paper http://wiki2.dovecot.org/Authentication/MasterUsers as guidance. The Dovecot server A, is not letting me authenticate. Follow the testing and debug below: Testing: # telnet <ip_address> 8143 Trying <ip_address>... Connected to <ip_address>. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot ready. a login mailadm*masteruser masterpass a NO [AUTHENTICATIONFAILED] Authentication failed. b logout * BYE Logging out b OK Logout completed.

POP/IMAP HA solution for 5k users
by Sinergizmas Sin ergizmas 28 Aug '14

28 Aug '14

Hello, I want to build simple, cheap HA solution for 5000 users with postfix/dovecot. Each user will have 1.3 GB mailbox (maildir) storage quota. All of the users will use POP and also plus half of them will use IMAP from smart phones. Sometimes they will hit webmail (squirrelmail). I plan that every user will send 20 and receive 20 mails per day. I have 3 locations, but electricity are not very stable there. We have outages for couple of hours 3-4 times per year. So I plan distribute all servers (it's more like good PC's) across locations. I'm very tied on budget also. Or maybe I could say I don't have it and I'm forced to use hardware equipment which is given. We are talking about quite pour HA solution here. Don't judge me please. I start to plan architecture and I would be very thankful for all your thoughts. I'm not expert in this area, but I need to learn, fire up email system and manage it. I will have SMTP server (smtp.example.com) which will filter mail with Clam, Spamassasin, Greylisting and forward emails to IMAP/ POP3/webmail server (mail.example.com) Mail.example.com will sync all user and mail changes to the third server mail2.example.com. Mail2.example.com server is just stand by, hot backup server in cases if main mail server or smtp will not be reachable. Locations of servers are in different cities: Locations #1 - SMTP servers as virtual machines (vmware server or virtualbox), with CPU i3, 6GB RAM, SSD, Centos 6, Virtualmin Location #2 - Dovecot/webmail server: CPU i5, 16GB RAM, HDD 1SSD for OS/dovecot indexes and SATA 2TBx4 LVM (total 8TB) for Maildir's, Centos 6, Virtualmin Location #3 HOT BACKUP (always online) server in case of mail.example.com or smtp.example.com failure, electricity outage and etc. It contains Dovecot/webmail server: CPU i3, 8GB RAM, HDD 1SSD for OS/dovecot indexes and SATA 2x4TB LVM (total 8TB), Centos 6, Virtualmin DNS configuration (and location number): IN MX 10 smpt.example.com. (#1) IN MX 20 mail.example.com. (#2) IN MX 30 mail2.example.com. (#3) .... smtp IN A aa.aa.aa.aa mail IN A bb.bb.bb.bb mail2 IN A cc.cc.cc.cc So I need to solve SMTP, POP, IMAP high availability tasks. SMTP I think will be ok for external users. SMTP feature has all three servers. If smtp.example.com server is offline mail is sent to mail.example.com If mail.example.com is offline, then mail is sent to mail2.example.com If mail2.example.com is offline, the senders SMTP server will hold an email in a queue by default for 3 days (in most cases) and will try to deliver in some intervals. Local (users of domain example.com) SMTP/POP/IMAP users will have problems, because their domain server will be dead. This means that connections from user MTA agents (outlook POP) could not be delivered because DNS A type record pointing to a degraded server. When problem with server mail.example.com (POP/IMAP/webmail) connectivity will happen, I think to login to DNS server and point record (A type) to a working server. So if server in location #2 mail.example.com is dead, I will change mail IN A bb.bb.bb.bb ----> cc.cc.cc.cc The same with the server smtp.example.com. If it's down, I will change mail IN A aa.aa.aa.aa ----> cc.cc.cc.cc I know that this method is not perfect because of ISP DNS caching around the globe, but this the only option I have. Most of my users use ISP that refresh DNS in a period of 30 minutes so it won't be very terrible to half of hour to wait for the connection. My questions: 1. Is this infrastructure is ok for 5000 users? If you think it's not, please write how many users it will serve "normally"? Or maybe I it could handle and 10 000 users load? 2. Is the logic of all setup is right in such situation like mine? What other problems could arise? 3. I prefer to create users from one server. So the LDAP option is the best for me? In case of LDAP it will be on server #2 and I need to replicate it to #3. Is it rigth? Then server #2 will be offline does #3 LDAP will take place? Or should I better use batch command to create user in each server per single command? Actually I do not want to manage and LDAP as extra service. I don't have experience with it. 4. The main problem is to synchronize maildir of POP/IMAP/webmail servers. Because of distance I do not want to use DRBD. It's not suitable for WAN connections. GlusterFS seems an option but.. I saw on internet users also having problems with it performance. Sometimes gluster hang and all cluster must be restarted. Maybe I can sync /home with gluster where maildir resides, but we need to take care of dovecot index and control files synchronization also. The performance of retrieving index'es by several thousands users every 2-5 minutes must be excellent. The only option I found is Dovecot Dsync (or newer Doveadm) command. I made initial tests on two servers, but only to get work with SSH command. The method using TCP connection doesn't work for me. So question, if I use SSH method in several thousand user system does it cause me trouble? SSH adds some overhead comparing to TCP. But could make a permament tunnel and TCP also would be quite secure. So please tell me what methods are you using to sync two mail servers (especially for POP accounts) in different locations? 5. File system. Is it ok to use EXT4 file system? I know that XFS is better in performance working with small files (maildir = a lot of small files), but in power outage it can become corrupted without journal. Thanks.
