[Dovecot] Problem after migrating from mbox to maildir and squirrelmail
by Wawan S 08 Jun '10

08 Jun '10

Hi all, I just finished migrating from mbox to maildir (and upgrade squirrelmail to the latest version) with some issue. We are using Postfix 2.3, Dovecot 1.2.7 and Squirrelmail 1.4.2. One of user report that suddenly all his Sent and Drafts emails were disapeared. After log in to webmail, I found out that there are 3 new folder called Drafts, Sent and Trash apart from Drafts,Sent,Trash underneath INBOX folder, and all his sent and draft emails were there. I thought I just move the email from Sent folder to the Sent underneath INBOX, but I was wrong. Now he got all sent emails in Sent items but after refreshed the webmail, INBOX wont open at all. it just blank but in the left side it said the amount of his email. what did i do wrong? is it something to do with the dovecot.index and index.cache or the uidlist? please enlighten me.... thank you Hendry

[Dovecot] dovecot transaction log permissions
by Jordan Tardif 08 Jun '10

08 Jun '10

So after some problems with NFS and transaction logs getting corrupted. Im tyring out storing them localy. via.. mail_location: maildir:~/Maildir:INDEX=/var/dovecot/indexes/%u the problem is with a large amount of users.. the indexes dir becomes huge with this setup. So a change to make this better is... mail_location: maildir:~/Maildir:INDEX=/var/dovecot/indexes/%d/%n to seperate the users dir's into domains. What seems to happen is dovecot creates the index's folder automaticly and its owned by that user.. eg.. drwx------ 3 10651674 2598184 4096 2010-06-02 19:08 domain.com this makes it so no other user of domain.com can get their transaction logs created cause the dir is owned by another user at that domain. Is there anyway around this? I see there used to be a umask option but that is gone in 1.2.x. -- Jordan Tardif DreamHost

[Dovecot] Questions about migration Sun Messaging -> Dovecot+Postfix+Ldap
by Javier de Miguel Rodríguez 07 Jun '10

07 Jun '10

Hello. We are planning a migration from Sun One Messaging Server to Dovecot+Postfix+Ldap. We are using Dovecot 1.2.11 with Sun One Directory Server 5.2 ldap (we will migrate to Directory Server 6.3.1) soon. In our University we have 65.000 students, 5.500 staff and 6.500 teachers. Our main ldap realm is dc=us,dc=es (us means University of Seville, Spain). We have two e-mail domains, @us.es (staff+teachers) and @alum.us.es (students). We use Sun One Directory Server to load data to our ldap from several sources (like Oracle databases, flat files, etc) Our ldap tree is like this: dc=us,dc=es | |----->ou=People,dc=us,dc=es // "special" users only used by apps | | |----->o=us.es,dc=us,dc=es // ldap branch for staff+teachers | | |----->o=alum.us.es,dc=us,dc=es // ldap branch for students A user id is unique, so there is only a "john_doe" in the ldap tree (I repeat, there is NOT uid=john_doe,o=us.es,dc=us,dc=es and uid=john_doe,o=alum.us.es,dc=us,dc=es). Below you will find a copy of the dovecot.conf and dovecot-ldap.conf. Our operating system is Red Hat Enteprise Linux 5 x64. These are our questions: 1) We are unable to make dbox work with quota, but we have no problem with maildir. Quota is stored in a ldap attibute called "mailQuota" 2) A user can be in different branches in the same time: for example, a teacher called pepito should be in the uid=pepito,o=us.es,dc=us,dc=es branch but if that teacher is also a student should have another ldap entry uid=pepitosurname,o=us.es,dc=us,dc=es. Our identity management is the piece of software that "promotes" a user in that case. How should we use "mail_location" to addres this? 3) We are planning to use two raid5 of 8 SAS 15.000 rpm disks for these mailboxes. We will use a "2.0, ajax-based webmail" like roundcube. Most of our users will use webmail (imap based). How many iops should we have in that enviroment? We would like to use dbox, but we are stuck in maildir because 1) 4) Some users could have their mailboxes "disabled". We use the following line: user_filter = (&(objectClass=inetorgperson)(uid=%n)(mailUserStatus=active)) but it does NOT work as expected. Any idea) 5) We are planning to use bacula to backup user mailboxes. Any known problem with this (i will ask in the bacula mailing list anyway) 6) I have read carefully perfomance in dovecot wiki. Can I use noatime in /etc/fstab safely with dovecot? Any perfomance hint apart from we already have in our config files? 7) When we set vacation messages they work but we see this error in the log: dovecot: deliver(jorgelp): file_dotlock_create(~/.dovecot.lda-dupes) failed: No such file or directory 8) When a user log in she uses his username "mary" (without @us.es or @alum.us.es) . Our dovecot search in all the ldap tree until it finds that uid. But we would like to store in our mail_location /buzones/us.es or /buzones/alum.us.es. How can we accomplish this? We should use the "upper branch name" as part of the mail_location. Thank you for your support (and for your patience).

Hi, I'm trying to configure shared mailboxes using ACLs. On dovecot 1.2.10 it works fine, but the same configuration on dovecot 2.0. beta4 doesn't work. When I try to access to the shared mailbox I get the following message: Query: SELECT "users/user2/INBOX" Reason Given: Mailbox doesn't exist: users/user2/INBOX In the next the dovecot -n output and the dovecot-ldap.conf content: # 2.0.beta4: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.9-89.ELsmp i686 Red Hat Enterprise Linux AS release 4 (Nahant Update 8) ext3 auth_mechanisms = plain login mail_debug = yes mail_gid = mailusers mail_location = maildir:/mnt/mbox1/mailusers/%n/Maildir mail_uid = mailusers namespace { inbox = yes location = prefix = separator = / type = private } namespace { hidden = no list = children location = maildir:/mnt/mbox1/mailusers/%%n/Maildir: INDEX=/mnt/mbox1/mailusers/%n/Maildir/users/%%n prefix = users/%%n/ separator = / subscriptions = no type = shared } passdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf driver = ldap } plugin { acl = vfile acl_shared_dict = file:/var/tmp/shared-mailboxes.db } service auth { user = root } ssl = no userdb { driver = passwd } userdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf driver = ldap } protocol imap { mail_plugins = quota imap_quota acl imap_acl # /usr/local/etc/dovecot/dovecot-ldap.conf hosts = ldap-vip base = o=mailusers user_attrs = mailQuota=quota_rule=*:backend=%$ user_filter = (&(objectClass=person)(|(uid=%u)(uid=%n))) pass_attrs = uid=user,userPassword=password pass_filter = (&(objectClass=person)(|(uid=%u)(uid=%n))) Regards, Pier Luigi

[Dovecot] mangled user_attrs from LDAP
by markham breitbach 07 Jun '10

07 Jun '10

I have setup dovecot to allow users to login using their email address or uid and have found a strange behaviour when the user logs in using the email address for a "username". I am using OpenLDAP for a backend data store with a rather customized schema. This behaviour occurs for both POP3 and IMAP logins. For some users it works as expected, but for others the pass_attrs->user does not get mapped back to the uid, but remains the mailLocalAddress (dovecot-ldap.conf is attached at the end of this post). Here is an excerpt from the logs for a working and a malfunctioning user. In both cases the users were logged directly into the pop3 port (ie. telnet <mailserver> 110) and used the fully qualified email address as the user (ie. foo(a)ex.tld) Jun 02 13:23:19 pop3-login: Info: Login: user=<foo>, method=PLAIN, rip=64.247.129.10, lip=64.247.129.10, secured Jun 02 13:23:19 POP3(foo): Info: Loading modules from directory: /usr/local/lib/dovecot/pop3 Jun 02 13:23:19 POP3(foo): Info: Module loaded: /usr/local/lib/dovecot/pop3/lib10_quota_plugin.so Jun 02 13:23:19 POP3(foo): Info: Effective uid=14921, gid=2000, home=/nonexistent Jun 02 13:23:19 POP3(foo): Info: Quota root: name=User quota backend=maildir args= Jun 02 13:23:19 POP3(foo): Info: Quota rule: root=User quota mailbox=* bytes=0 messages=0 Jun 02 13:23:19 POP3(foo): Info: maildir: data=/var/mail/foo Jun 02 13:23:19 POP3(foo): Info: maildir++: root=/var/mail/foo, index=, control=, inbox=/var/mail/foo Jun 02 13:23:19 POP3(foo): Info: Namespace : Using permissions from /var/mail/foo: mode=0700 gid=-1 Jun 02 16:54:06 pop3-login: Info: Login: user=<bobs>, method=PLAIN, rip=199.247.84.12, lip=64.247.129.4 Jun 02 16:54:06 POP3(bob_smith(a)example.tld): Info: Loading modules from directory: /usr/local/lib/dovecot/pop3 Jun 02 16:54:06 POP3(bob_smith(a)example.tld): Info: Module loaded: /usr/local/lib/dovecot/pop3/lib10_quota_plugin.so Jun 02 16:54:06 POP3(bob_smith(a)example.tld): Info: Effective uid=38538, gid=2000, home=/nonexistent Jun 02 16:54:06 POP3(bob_smith(a)example.tld): Info: Quota root: name=User quota backend=maildir args= Jun 02 16:54:06 POP3(bob_smith(a)example.tld): Info: Quota rule: root=User quota mailbox=* bytes=524288000 messages=0 Jun 02 16:54:06 POP3(bob_smith(a)example.tld): Info: Quota rule: root=User quota mailbox=Trash bytes=52428800 messages=0 Jun 02 16:54:06 POP3(bob_smith(a)example.tld): Info: Quota rule: root=User quota mailbox=Deleted Messages bytes=52428800 messages=0 Jun 02 16:54:06 POP3(bob_smith(a)example.tld): Info: maildir: data=/var/mail/bob_smith(a)example.tld Jun 02 16:54:06 POP3(bob_smith(a)example.tld): Info: maildir++: root=/var/mail/bob_smith(a)example.tld, index=, control=, inbox=/var/mail/bob_smith(a)example.tld Jun 02 16:54:06 POP3(bob_smith(a)example.tld): Info: Namespace : Using permissions from /var/mail/bob_smith(a)example.tld: mode=0700 gid=-1 Jun 02 16:54:10 POP3(bob_smith(a)example.tld): Info: Disconnected: Logged out top=0/0, retr=0/0, del=0/0, size=0 After much searching for anything different between these records, some tcpdumps showed that the problem occured when LDAP returned the attributes in a different order than they are requested in. In this sample, you can see the request for uid,homeDirectory,uidNumber,gidNumber,mailQuota and the values are returned in the order gidNumber, uid, uidNumber, homeDirectory. There is no mailQuota set for this user. 16:54:06.145597 IP mail.xxxxx.com.62929 > closest-ldap.ldap: P 14:261(247) ack 15 win 33304 <nop,nop,timestamp 1521221146 267819447> 0x0000: 4500 012b fd4d 4000 4006 b87a 40f7 8104 E..+.M@.@..z@... 0x0010: 40f7 8112 f5d1 0185 41e1 8b7d 5aea 01d9 @.......A..}Z... 0x0020: 8018 8218 8522 0000 0101 080a 5aab fe1a ....."......Z... 0x0030: 0ff6 99b7 3081 f402 0120 6381 ee04 0b64 ....0.....c....d 0x0040: 633d 322c 6463 3d73 7369 0a01 020a 0100 c=2,dc=ssi...... 0x0050: 0201 0002 0100 0101 00a0 8198 a317 040d ................ 0x0060: 6163 636f 756e 7473 7461 7475 7304 0661 accountstatus..a 0x0070: 6374 6976 65a3 1c04 1265 6d61 696c 6163 ctive....emailac 0x0080: 636f 756e 7453 7461 7475 7304 0661 6374 countStatus..act 0x0090: 6976 65a1 5fa3 2704 0375 6964 0420 626f ive._.'..uid..bo 0x00a0: 625f 6d61 6364 6f6e 616c 6440 6772 6561 b_xxxxxxxxx@xxxx 0x00b0: 7473 6c61 7665 6865 6c69 2e63 6f6d a334 xxxxxxxxxx.com.4 0x00c0: 0410 6d61 696c 4c6f 6361 6c41 6464 7265 ..mailLocalAddre 0x00d0: 7373 0420 626f 625f 6d61 6364 6f6e 616c ss..bob_xxxxxxxx 0x00e0: 6440 6772 6561 7473 6c61 7665 6865 6c69 x@xxxxxxxxxxxxxx 0x00f0: 2e63 6f6d 3035 0403 7569 6404 0d68 6f6d .com05..uid..hom 0x0100: 6544 6972 6563 746f 7279 0409 7569 644e eDirectory..uidN 0x0110: 756d 6265 7204 0967 6964 4e75 6d62 6572 umber..gidNumber 0x0120: 0409 6d61 696c 5175 6f74 61 ..mailQuota 16:54:06.147464 IP closest-ldap.ldap > mail.xxxxx.com.62929: P 15:142(127) ack 261 win 32942 <nop,nop,timestamp 267819449 1521221146> 0x0000: 4500 00b3 bb91 4000 4006 faae 40f7 8112 E.....@.@...@... 0x0010: 40f7 8104 0185 f5d1 5aea 01d9 41e1 8c74 @.......Z...A..t 0x0020: 8018 80ae b708 0000 0101 080a 0ff6 99b9 ................ 0x0030: 5aab fe1a 307d 0201 2064 7804 1663 6e3d Z...0}...dx..cn= 0x0040: 6773 6862 6f62 6d2c 6463 3d32 2c64 633d xxxbobx,dc=2,dc= 0x0050: 7373 6930 5e30 1304 0967 6964 4e75 6d62 ssi0^0...gidNumb 0x0060: 6572 3106 0404 3230 3030 3010 0403 7569 er1...20000...ui 0x0070: 6431 0904 0767 7368 626f 626d 3014 0409 d1...xxxbobx0... 0x0080: 7569 644e 756d 6265 7231 0704 0533 3835 uidNumber1...385 0x0090: 3338 301f 040d 686f 6d65 4469 7265 6374 380...homeDirect 0x00a0: 6f72 7931 0e04 0c2f 6e6f 6e65 7869 7374 ory1.../nonexist 0x00b0: 656e 74 ent I will spare you the packet dump, but in the cases where the login works correctly, LDAP returns the values in the same order that they are requested in. This behaviour has been found with both OpenLDAP: slapd 2.3.39 and OpenLDAP: slapd 2.4.17, and is consistent with standard LDAP behaviour (ie, there is no guaranteed ordering in the LDAP database). A brief look at the code, seems to indicate that the values are being pulled from the LDAP return struct in a step-wise manner, which could certainly put them out of sync with the request if it is assumed that they will always be returned in the same order....This is just based on a quick review of the code though, and not any detailed tracing.

[Dovecot] Expunge Logging Patch
by James Devine 07 Jun '10

07 Jun '10

I have made some changes to the expunge logging as client->mailbox is set to NULL prior to one of the relevant calls. The change leaves mailbox in the function now and adds client. The modified patch to 1.2.11 is included.

[Dovecot] Ignoring the quota by the LDA?
by Holger Richter 07 Jun '10

07 Jun '10

Is it possible to configure dovecot in a manner that only the imap process respects the quota, and the local delivery ignores completely the quota? I think it should happen if I don't activate the quota plugin in the lda section but only in the imap section. protocol lda { ... # mail_plugins = ... } protocol imap { ... mail_plugins = quota imap_quota ... } Will it work or will it result in a big mess? I've the aim that a mail will never be rejected because the recipient is over his/her quota. Regards, Holger

[Dovecot] Problems with the IMAP proxy after upgrading from dovecot 1.1.16 to 1.211
by Holger Richter 07 Jun '10

07 Jun '10

We have frequent timeout problems after upgrading our imap servers from dovecot 1.1.16 to dovecot 1.2.11. One server acts as proxy only, and the other one is the "real" imap server". The credentials for the proxy service are stored in a remote MYSQL database. There were no trouble with dovecot 1.1.16. But now, with the most recent version, we get frequent login failures. It seems dovecot reconnects too late to the MySQL database after a timeout, after sending the SQL query. Here's a piece of my log file: May 7 14:46:32 ttt dovecot: auth(default): new auth connection: pid=5136 May 7 14:46:42 ttt dovecot: auth(default): client in: AUTH^I1^IPLAIN^Iservice=imap^Isecured^Ilip=xxx.xxx.xxx.xxx^Irip=yyy.yyy.yyy.yyy^Ilport=sss^Irport=26480^Iresp=<hidden> May 7 14:46:42 ttt dovecot: auth-worker(default): sql(uid,yyy.yyy.yyy.yyy): query: SELECT NULL as password, destuser, host, 'zzz' as port, 'Y' as proxy, '0' as proxy_timeout, 'Y' as nopassword, 'Y' as nodelay from accounts where user ='uid'; May 7 14:47:42 ttt dovecot: auth(default): worker-server(uid,yyy.yyy.yyy.yyy): Aborted: Lookup timed out May 7 14:47:42 ttt dovecot: auth-worker(default): mysql: Connected to lll.lll.lll.lll (imapauth) May 7 14:47:44 ttt dovecot: auth(default): client out: FAIL^I1^Iuser=uid^Itemp May 7 14:47:49 ttt dovecot: imap-login: Disconnected (auth failed, 1 attempts): user=<uid>, method=PLAIN, rip=yyy.yyy.yyy.yyy, lip=xxx.xxx.xxx.xxx, TLS May 7 14:48:26 ttt dovecot: auth(default): new auth connection: pid=5159 May 7 14:48:47 ttt dovecot: auth(default): client in: AUTH^I1^IPLAIN^Iservice=imap^Isecured^Ilip=xxx.xxx.xxx.xxx^Irip=yyy.yyy.yyy.yyy^Ilport=sss^Irport=6243^Iresp=<hidden> May 7 14:48:47 ttt dovecot: auth-worker(default): sql(uid,yyy.yyy.yyy.yyy): query: SELECT NULL as password, destuser, host, 'zzz' as port, 'Y' as proxy, '0' as proxy_timeout, 'Y' as nopassword, 'Y' as nodelay from accounts where user ='uid'; May 7 14:48:47 ttt dovecot: auth(default): client out: OK^I1^Iuser=uid^Idestuser=luid^Ihost=mmm.mmm.mmm.mmm^Iport=zzz^Iproxy^Iproxy_timeout=0^Ipass=<hidden> May 7 14:48:47 ttt dovecot: imap-login: proxy(uid): started proxying to mmm.mmm.mmm.mmm:zzz/luid: user=<uid>, method=PLAIN, rip=yyy.yyy.yyy.yyy, lip=xxx.xxx.xxx.xxx, TLS May 7 14:48:48 ttt dovecot: imap-login: proxy(uid): disconnecting yyy.yyy.yyy.yyy As you can see, the second login attempt is always successful.

[Dovecot] authentification failure: double quotes in password
by Martin Ott 07 Jun '10

07 Jun '10

we use Passdb LDAP with authentication binds against an Active Directory Server. The problem with one of our users seems to be the usage of double quotes in his password, as the windows-login works: /var/log/dovecot-info.log auth(default): Info: ldap(testuser 77.22.xx.xxx): invalid credentials (given password: xxxxx"xxxxxxx) Which chars in passwords does the dovecot auth process not like? Is there something similar to auth_username_chars for passwords? thanks, martin

[Dovecot] DOES NOT PERTAIN TO DOVECOT: Does anyone use postfix for some help?
by Jerrale Gayle 05 Jun '10

05 Jun '10

When mail is sent from the mail server, it shows up as originating from the MAIN ip address of the server, 173.50.101.11, when the mail server is bound to 173.50.101.12. I have already set smtp_bind_address: 173.50.101.12 in main.cf and 173.50.101.12:smtp inet - - smtpd in master.cf. This prevents smtp connects TO any other ip but 173.50.101.12 BUT mail STILL shows up originating from eth1, where 173.50.101.12 is eth1:2 I think this is *nix related and most here, on dovecot mailing list, could provide help.

[Dovecot] mdbox error with 2.0.beta5

Running 2.0.beta5 on Mac OS X with HFS+J, I often see this error in the log: Fri May 14 12:25:59 gromit dovecot[5466]: imap(pid 8101 user joe): Error: mdbox /var/spool/imap/dovecot/mail/mailboxes/INBOX/Foobar/dbox-Mails: map uidvalidity mismatch (1273852899 vs 1273853949) Fri May 14 12:25:59 gromit dovecot[5466]: imap(pid 8101 user joe): Disconnected: Internal error occurred.

There appear to be two issues here: the uidvalidity mismatch, and the path in the "rebuilding indexes" message does not match the path in the "uidvalidity mismatch" error.

[Dovecot] Managesieve connection hangs with TLS
by Joel James Adamson 04 Jun '10

04 Jun '10

Hello, I've got dovecot 1.2.11 running on Fedora 12 (x86_64) with the managesieve protocol and sieve plugins enabled, with deliver handling local delivery. I've set disable_plaintext_auth = yes ssl = yes ssl_cert_file = /etc/pki/dovecot/certs/dovecot.pem ssl_key_file = /etc/pki/dovecot/private/dovecot.pem mail_debug = yes protocol managesieve { listen = *:2000 login_executable = /usr/libexec/dovecot/managesieve-login mail_executable = /usr/libexec/dovecot/managesieve } and generated local SSL certificates; everything is going fine on the IMAP end of things (clients ask if I trust the certificate the first time, etc). I've open the appropriate ports, etc. No problems with mail delivery. However, I can't connect to the managesieve daemon. I've tried the Emacs client[1], and it just hangs. I tried manual login to port 2000 and here's what happened: joel@chondestes: /etc/mail > gnutls-cli --starttls -p 2000 localhost Resolving 'localhost'... Connecting to '127.0.0.1:2000'... - Simple Client Mode: "IMPLEMENTATION" "dovecot" "SIEVE" "comparator-i;octet comparator-i;ascii-casemap fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date" "SASL" "PLAIN" "STARTTLS" "NOTIFY" "mailto" "VERSION" "1.0" OK "Dovecot ready." *** Starting TLS handshake C-c C-c That last line is me hanging up in Emacs' shell buffer because nothing was happening. Sorry to sound like such a newbie, but what do I need on the client end to complete the TLS transaction? What else do I need to set up to get managesieve to connect?

Hello, I'm seeing * BAD Internal quota calculation error's with dovecot 2.0. It doesn't happen always but quite frequently.

Reverting the following change fixes the issue http://hg.dovecot.org/dovecot-2.0/rev/50a0c05fb4e7 Thanks, e-frog

[Dovecot] dsync panic in dsync-worker-local.c - 2.0.beta4
by Frode Nordahl 04 Jun '10

04 Jun '10

Hello, While testing mailbox conversion I encountered a Panic in dsync on a few users mailboxes. Running dovecot 2.0.beta4 on RedHat Enterprise Linux 5 (x86_64). I tried to compile the code with -ggdb and debug some more before posting this, but I was unsuccessful. Running dsync from a source tree is hard because of all the dependencies on shares libraries. Is it possbile to build static binaries? Panic message and backtrace included below (anonymized): dsync(user): Error: o_stream_send_istream(/home/user/mdbox/storage/temp.1271871137.P25074Q1M330350.localhost.localdomain) failed: Bad file descriptor dsync(user): Panic: file dsync-worker-local.c: line 1460 (local_worker_save_msg_continue): assertion failed: (ret == -1) dsync(user): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0 [0x3da92343a0] -> /usr/lib64/dovecot/libdovecot.so.0(default_fatal_handler+0x37) [0x3da9234487] -> /usr/lib64/dovecot/libdovecot.so.0 [0x3da92338c8] -> /usr/bin/dsync [0x40db83] -> /usr/bin/dsync [0x40dc5e] -> /usr/bin/dsync(dsync_worker_msg_save+0x79) [0x40d429] -> /usr/bin/dsync [0x408b4c] -> /usr/bin/dsync [0x40d88d] -> /usr/bin/dsync(dsync_worker_msg_get+0x81) [0x40d061] -> /usr/bin/dsync [0x4085fe] -> /usr/bin/dsync [0x40868d] -> /usr/bin/dsync [0x4087d5] -> /usr/bin/dsync(dsync_brain_msg_sync_more+0x3f5) [0x408395] -> /usr/bin/dsync(dsync_brain_sync+0x93f) [0x40720f] -> /usr/bin/dsync [0x4078e0] -> /usr/bin/dsync(dsync_brain_sync+0x42e) [0x406cfe] -> /usr/bin/dsync [0x4079e1] -> /usr/bin/dsync(dsync_brain_sync+0x3f0) [0x406cc0] -> /usr/bin/dsync(dsync_brain_sync_all+0x18) [0x407728] -> /usr/bin/dsync(main+0x436) [0x406156] -> /lib64/libc.so.6(__libc_start_main+0xf4) [0x3d18a1d994] -> /usr/bin/dsync [0x405c29] -- Frode Nordahl

[Dovecot] 'doveadm who' enhancement request
by Brad Davidson 04 Jun '10

04 Jun '10

When Dovecot is in proxy mode, the client sends along the original connection endpoints in an ID command. Is there any chance 'doveadm who' could use this to display the original connection source? As it currently stands, all I see is a bunch of connections from the proxy. Thanks! --- Brandon 'Brad' Davidson Virtualization Systems Administrator University of Oregon Information Services (541) 346-8098 brandond(a)uoregon.edu

Hi Timo, I've just tried to convert my v1.2 configuration to a v2.0 configuration.

[Dovecot] Auto forward virtual users mail using Sieve
by Julian Baker 04 Jun '10

04 Jun '10

Hi All I'm trying to configure Dovecot to automatically forward mail to another account without the virtual user having to log-in first to Roundcube web mail. These are virtual users with no log-in to the server only Roundcube's web interface The situation is that I have two domains only who want to receive email at their domains, get a forwarded copy at their hotmail account, then log-in to Roundcube to reply. A Sieve script running in Dovecot seems the way to go, but the finer points of configuration have failed me. I got as far as 1) /etc/dovecot/dovecot.conf Adding: protocol lda { mail_plugins = cmusieve mail_plugin_dir = /usr/lib/dovecot/modules/lda } 2) /var/vmail/___domain___/___user___/.dovecot.sieve Created the .dovecot.sieve file in the domain/user directory and added: require ["fileinto ","reject","vacation","imapflags","relational","regex","notify"]; # Resend a copy of the message to another address # if true { redirect "julian(a)flatearth.co.uk"; } Which doesn't seem to have broken anything. Or worked. I'm assuming that as /var/vmail/___domain___/___user___/ is their virtual user home/mail spool the '.dovecot.sieve' file will get picked up. It seems that Dovecot isn't configured to use send via Deliver ? My conf is pasted before (Exim handles regular domain email forwarding mail for a bunch of virtual domains to pop accounts.)

[Dovecot] auth socket goes away on reload
by David Jonas 03 Jun '10

03 Jun '10

We're using the SQLite backend for authentication of Postfix SASL. When the db is replaced we HUP dovecot to close and reopen its connection. During this time it appears the socket file is removed and Postfix rejects the authentication attempt. From the logs: Jun 3 00:23:02 xxx dovecot: dovecot: SIGHUP received - reloading configuration Jun 3 00:23:02 xxx postfix/smtpd[14746]: warning: SASL: Connect to private/auth failed: Connection refused Jun 3 00:23:02 xxx postfix/smtpd[14746]: warning: unknown[dd.dd.dd.dd]: SASL LOGIN authentication failed: Jun 3 00:23:02 xxx postfix/smtpd[14746]: NOQUEUE: reject: RCPT from unknown[dd.dd.dd.dd]: 554 5.7.1 <user(a)example.com>: Relay access denied; from=<user2(a)example.com> to=<user(a)example.com> proto=ESMTP helo=<localhost.localdomain> Jun 3 00:23:02 xxx postfix/smtpd[14930]: warning: unknown[dd.dd.dd.dd]: SASL LOGIN authentication failed: Connection lost to authentication server Jun 3 00:23:02 xxx postfix/smtpd[14930]: lost connection after AUTH from unknown[dd.dd.dd.dd] Is there an obvious way around this? I know I could somehow merge the changes into the running sqlite db but that undermines the simplicity of the design I have. Maybe a patch to reopen the db if it's replaced? Or perhaps I should just switch to a different db format -- that's probably the quickest/easiest solution. Any other ideas? There are about 20k entries to deal with. Thanks, David

Hi, i think ive asked it before perhaps this feature can be included in dovecot2 couldnt get it run with dovecot 1.2.x if i use the postfixadmin superuser,domainadmin,domainuser layout so there are domainadmins defined in a sql table it would be a nice feature to break it down to be master only at there related domains via sql lookup at recent i think there is only the chance to give master rights to all adresses for users defined as masters -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] Dovecot aspects of fighting spam
by Phil Howard 02 Jun '10

02 Jun '10

I see no documents in the Dovecot documents wiki on how Dovecot features can be used in the fight against spam. One hit came up in a search, and it was about how to fight spam in the MoinMoin Wiki itself (e.g. TextCHAs and such). I already asked in another thread about removing message files at the search from a designated "learn-spam" folder. My next question would be how to automatically place detected spam into a specific folder for the user to access or ignore as they deem fit. That would seem to me to be something for the deliver command and its -m option. But this might be more of a Dovecot and MTA coordination issue, too (e.g. how to get the spam detection done in the MTA ... Postfix in my case ... to become a label of some sort that ends deciding the folder. The -m option might be harder to get it dynamically set since it would be hard coded in master.cf for Postfix (so a variable has to be able to direct it to INBOX in this case). But maybe the "standard" way of doing this is to shim another program between the MTA (Postfix for me) and the LDA (Dovecot deliver) to dynamically add the -m option on the fly? Lacking any other clever solution, this seems to me to be the way I could make it work. Maybe there is a special header deliver could detect, such as "X-Spam: yes"? A wiki document on how Dovecot helps (or how to help Dovecot) in the fight against spam, I think, would be helpful.

[Dovecot] configuring sendmail to work with dovecot+LDAP
by Douglas Maus 02 Jun '10

02 Jun '10

I would like to setup dovecot (1.1.20) with LDAP virtual users, but I don't seem to understand how to get my sendmail to accept mail for the virtual users. (I am rather new to this, so I may have some misunderstandings) I have followed - wiki.dovecot.org/HowTo/DovecotOpenLdap (OpenLDAP 2.3.43) and I think I have IMAP working for virtual users. I can connect to port 143, enter a username and password and it works. Now I surmise I need to configure my SMTP server to accept mail for these LDAP virtual users, and deliver it appropriately. (The above HowTo doesn't address this step, from what I can tell) I read - wiki.dovecot.org/LDA and wiki.dovecot.org/LDA/Sendmail (I'm using OpenBSD 4.7, which uses sendmail for MTA / SMTP server, sendmail version 8.14.3) For sendmail.cf, I made the changes in my sendmail.mc file to include the dovecot mailer (calling /usr/local/libexec/dovecot/deliver), and compiled with m4 and installed the new sendmail.cf For dovecot.conf, I edited the portions (abbreviated): protocol lda { auth_socket_path = /var/run/dovecot/auth-master } and auth default { socket listen { master {path = /var/run/dovecot/auth-master }}} When I try to test this, (telnet www.example.org 25) If I try: MAIL TO:jdoe@www.example.org I get "User unknown" I see that if I try: MAIL TO:jdoe@example.org I get "Relaying denied" Either way it doesn't get delivered. Thank you for any help. And if anyone knows a good basic tutorial for dovecot+LDAP+sendmail I would really appreciate it. dovecot -n (de-identified, and yes I know SSL is disabled, after it all works I'll fix it) ---------- # 1.1.20: /etc/dovecot.conf Warning: fd limit 128 is lower than what Dovecot can use under full load (more than 640).

[Dovecot] Migration - Dovecot to Dovecot
by Greg Pearson 02 Jun '10

02 Jun '10

Hi, I am using Dovecot with mbox format, and I am interested to move to Maildir. I have run the modified script (mb2md) but it seems UIDs are not preserved. I don't know how to verify this, but my client seems to be downloading all messages again. Can someone help?

[Dovecot] recipient_delimiter
by Phil Howard 02 Jun '10

02 Jun '10

I have recipient_delimiter = + in main.cf (Postfix). But deliveries to dovecot/deliver are still being rejected. It appears that the full email is still in the envelope (e.g. phil+howard(a)example.com which I want to be delivered to phil(a)example.com) Is that how it's supposed to work and Dovecot just doesn't support this?

[Dovecot] Intermittent timeout issues
by Del Stoliker 01 Jun '10

01 Jun '10

Greetings list! We've been experiencing an intermittent issue in which none users are able to log into the mail server for about 10 to 20 minutes. This issue first appeared on our CentOS 4 box running dovecot 1.2.11 after upgrading from the stock version 0.99. The issue persists after migrating our users to a CentOS 5 server - also running version dovecot 1.2.11 but now in the 64-bit flavor. Our users authenticate against LDAP via PAM in case that might be relevant. I've yet to find anything "of interest" in the logs covering the outages. But here is what I've noticed: * Users on our internal network are still able to authenticate and login. * Users from the outside are "Disconnected for inactivity" * Immediately after the restart, external users were able to log in again. It almost sounds like the firewall is blocking external access except that: * The version of dovecot was the thing that changed * Everything starts working again after a dovecot restart If anyone could provide some insight, I'd sure appreciate it.

[Dovecot] purge maildir folder after sa-learn
by Florian Effenberger 01 Jun '10

01 Jun '10

Hello, I am looking for a command-line utility to automatically purge one Maildir folder. I want to periodically run sa-learn from cron, and after the spam learning folder has been added to the Bayes database, its contents should be deleted. I've searched a bit, but only found a few old utilities or some telnet+expect scripts, which both didn't look too reliable. Is there any command-line utility to delete all contents of a Maildir folder, or is there any other solution? Thanks, Florian

Hello Dovecot admins. I've started writing manual pages for Dovecot v2.0. I'm sure they are not perfect yet. I'd like to ask you all to read the manual pages. It would be nice to get some ideas/suggestions/improvements. So that that the Dovecot v2.0.0 release could be distributed with /fine manuals/. The manual pages are available at: http://wiki2.dovecot.org/ManPages This is also the intended place for 'discussions' about the man pages.

[Dovecot] dovecot-2.0-pigeonhole/ManageSieve: wrong service name
by Pascal Volk 31 May '10

31 May '10

Hi Stephan, ManageSieve uses the wrong™ service name for the authdb lookup. With dovecot-1.2-managesieve the service name was changed from 'managesieve' to 'sieve'. So I altered my table layout in order to make the query "SELECT userid AS "user", password FROM dovecotpassword('%Ln', '%Ld') WHERE %Ls" work again. When I try to login on the sieve port 4190/tcp, I find this in my dovecot.log: auth: Error: pgsql: Query failed, retrying: ERROR: column "managesieve" does not exist auth: Error: LINE 1: ...", password FROM dovecotpassword('user', 'example.org') WHERE managesiev...

[Dovecot] Permanent flags not announced and public mailbox with per-user index
by Julien Danjou 31 May '10

31 May '10

Hi, I've a set of public mailboxes that all users can access. The index is stored per user, so each user can mark the message as read for themselves. This is with dovecot 1.2.10. However, when selecting the mailbox, system flags are not announced as permanent but only as session flags: 3619 SELECT "public.Admin" * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS ()] Read-only mailbox. * 324 EXISTS * 0 RECENT * OK [UNSEEN 171] First unseen. * OK [UIDVALIDITY 1254326934] UIDs valid * OK [UIDNEXT 1102] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest 3445 OK [READ-ONLY] Select completed. I think (reading the RFC, but I bet you know it better than me) that FLAGS should also been set in PERMANENTFLAGS since they can be permanent. The relevant code seems to be in commands-util.c (dovecot 1.2.11): void client_send_mailbox_flags(struct client *client, bool selecting) { […] if (mailbox_is_readonly(client->mailbox)) { client_send_line(client, "* OK [PERMANENTFLAGS ()] " "Read-only mailbox."); } else { […] } } Even if it's true that the Maildir is read-only, it's still possible to store \Seen permanently. Am I getting things wrong, or is this a bug? If I'm correct, a simple fix MAY be not to send the PERMANENTFLAGS at all since the RFC says: OK [PERMANENTFLAGS (<list of flags>)] A list of message flags that the client can change permanently. If this is missing, the client should assume that all flags can be changed permanently. Thanks, -- Julien Danjou // ᐰ <julien(a)danjou.info> http://julien.danjou.info

As this is a fresh installation of dovecot I do not know if older versions work better.

[Dovecot] 1.2.11, mbox, new mail
by Stan Hoeppner 31 May '10

31 May '10

With 1.2.11 and mbox storage, the delay time in pulling new mail headers to the client from imap folders seems to be directly proportional to mailbox size, regardless of the number of new messages. At present, if the mailbox is large, pulling new headers is rather painfully slow. Is this expected behavior? Especially given that the client already has all the "old" mails in the folder cached, and thus wouldn't be asking for them? Is there a setting(s) I can change to optimize/fix this? -- Stan

[Dovecot] strange sieve situation
by Andy Dills 31 May '10

31 May '10

Hi there, I've been working on rolling out the "deliver" service so we can implement sieve. Dovecot 1.2.11, Postfix 2.6.6, FreeBSD 8, installed by ports. Clustered environment, NFS backend. Everything is working great for the most part, I'm using it to sort a copy of my personal email on a test server. However, I noticed two emails were not properly sorted. I had added a rule (using Ingo, nice little piece of software) to redirect the nightly FreeBSD security output emails into a folder "servers". However, nothing had triggered that rule, and the "Maildir/.servers" directory had not yet been created. Then, three of the "security outputs" came in at one time: May 29 03:01:48 mg8 dovecot: deliver(andytest(a)xecu.net): sieve: msgid=<20100529070108.F2F0B7F5D4(a)mail-out04.xecu.net>: failed to store into mailbox 'servers': Mailbox already exists May 29 03:01:48 mg8 dovecot: deliver(andytest(a)xecu.net): sieve: msgid=<20100529070109.D8F5E159913(a)mail-out01.xecu.net>: failed to store into mailbox 'servers': Mailbox already exists May 29 03:01:48 mg8 dovecot: deliver(andytest(a)xecu.net): sieve: msgid=<20100529070109.D8F5E159913(a)mail-out01.xecu.net>: stored mail into mailbox 'INBOX' May 29 03:01:48 mg8 dovecot: deliver(andytest(a)xecu.net): sieve: execution of script /mail/var/mail2/xecunet/andytest.xecu.net//.dovecot.sieve failed, but implicit keep was successful May 29 03:01:48 mg8 dovecot: deliver(andytest(a)xecu.net): sieve: msgid=<20100529070110.17A781B53B9(a)mail-out02.xecu.net>: stored mail into mailbox 'servers' May 29 03:01:48 mg8 dovecot: deliver(andytest(a)xecu.net): sieve: msgid=<20100529070108.F2F0B7F5D4(a)mail-out04.xecu.net>: stored mail into mailbox 'INBOX' May 29 03:01:48 mg8 dovecot: deliver(andytest(a)xecu.net): sieve: execution of script /mail/var/mail2/xecunet/andytest.xecu.net//.dovecot.sieve failed, but implicit keep was successful That's the order they appeared in my logfile. I'm assuming they were all sent to deliver at the same time, they all thought they needed to make the directory, the one with msgid 20100529070110.17A781B53B9(a)mail-out02.xecu.net was able to make the directory and get delivered, whereas the other two freaked out because they couldn't make the directory they thought needed to be made, and just sent the mail to the inbox. That's a reasonable approach, although I wonder if deliver/sieve could be (or perhaps "has been in 2.0") adjusted to more intelligently handle that edge case. Also, I'm wondering about "dovecot_destination_recipient_limit = 1". I have that set in my main.cf, but I'm not 100% positive it's taking effect. # grep dovecot /usr/local/etc/postfix/main.cf dovecot_destination_recipient_limit = 1 virtual_transport = dovecot # grep dovecot /usr/local/etc/postfix/master.cf dovecot unix - n n - - pipe flags=DRhu user=mailman argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${recipient} # postconf | grep dovecot smtpd_sasl_type = dovecot virtual_transport = dovecot # postconf | grep destination_recipient_limit default_destination_recipient_limit = 50 lmtp_destination_recipient_limit = $default_destination_recipient_limit local_destination_recipient_limit = 1 relay_destination_recipient_limit = $default_destination_recipient_limit smtp_destination_recipient_limit = $default_destination_recipient_limit virtual_destination_recipient_limit = $default_destination_recipient_limit Is "dovecot_destination_recipient_limit" being converted into local_ ?

[Dovecot] Unresolved client rejection
by Greg Pearson 31 May '10

31 May '10

Hi, would it be possible to prevent users who try to login from an unresolved IP from connecting to Dovecot IMAP? I have a suspicion that it should be done via the authentication module (ie PAM) but I am not sure (if this is the case could someone recommend a good resource or even a solution). For example sendmail has a relevant macro to achieve this, I was wondering if Dovecot can have similar behavior. Thanks

[Dovecot] imap folder aliases for different mail clients naming convention
by Robert Schetterer 31 May '10

31 May '10

Hi, sorry if this was asked before and/or if there is allready a solution different imap mail clients, have different imap folder naming conventions typical by sent , trash, spam i normally use thunderbird conventions, as its working on all major plattforms and configure hord/imp , squirrelmail to use it like thunderbird does, additional i use autocreate with this folders it would be nice to alias other mail clients naming conventions to TB folder naming conventions without poke around with i.e symlinks etc, i guess there might be some solution with namespaces but i hope i could be done more easy eventually with a alias plugin etc? -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

( dovecot2/srv/lmtp/commands.c ~line 695 ) has somebody experiences while delivering huge ammount of mail via dovecot2 lmtp service? - is it faster/slower/comaparable with deliver? - it's hard to believe, that nobody realy misses the return-path header Thanks, Andreas -- Andreas Schulze Internetdienste | P532 DATEV eG 90329 Nürnberg | Telefon +49 911 319-0 | Telefax +49 911 319-3196 E-Mail info @datev.de | Internet www.datev.de Sitz: 90429 Nürnberg, Paumgartnerstr. 6-14 | Registergericht Nürnberg, GenReg Nr.70 Vorstand Prof. Dieter Kempf (Vorsitzender) Dipl.-Kfm.

[Dovecot] Dovecot 1.2 - Quotas - Ignoring Trash folder
by Shayne Jellesma 30 May '10

30 May '10

Hello guys, Firstly I would like to state that I am fairly new to Dovecot. I have played around with it in the past here and there but mainly with debian packages. I have compiled this version of Dovecot from source, so please go easy with me. Ok now down to my questions: I am having trouble getting Dovecot to 'ignore' the Trash folder when summing up the used quota for a user. I am running Dovecot 1.2.11 (with LDA), Postfix 2.5.5, and Postfixadmin 2.3. I am able to send and receive emails fine. Roundcube displays the quota used but this quota also counts what is in the users Trash can. Postfix is configured to hand over delivering of the mail to Dovecot. I have tried different methods from the documentation on ignoring the Trash folder, but have not come up with anything that has worked yet. If someone could point me in the right direction, that would be great. I apologise now if I have not included all required information, I did read the mailing list guidelines and believe I have follow all required steps. charged:/usr/local/etc# dovecot --version 1.2.11 charged:/usr/local/etc# charged:/usr/local/etc# dovecot -n # 1.2.11: /usr/local/etc/dovecot.conf # OS: Linux 2.6.26-2-686 i686 Debian 5.0.4 ext3 base_dir: /var/run/dovecot/ log_path: /var/log/dovecot12.log info_log_path: /var/log/dovecot12.log protocols: imap imaps pop3 pop3s listen: 118.127.29.214 disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login first_valid_uid: 5000 last_valid_uid: 5000 first_valid_gid: 5000 last_valid_gid: 5000 mail_privileged_group: vmail mail_uid: 5000 mail_gid: 5000 mail_location: maildir:/var/vmail/%d/%n/Maildir mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 namespace: type: private separator: . inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)ignitioncarclub.com mail_plugins: quota mail_plugin_dir: /usr/local/lib/dovecot/lda quota_full_tempfail: no auth_socket_path: /var/run/dovecot/auth-master auth default: mechanisms: plain login passdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: sql args: /usr/local/etc/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail plugin: quota: maildir:ignore=Trash trash: /usr/local/etc/dovecot-trash.conf charged:/usr/local/etc# charged:/usr/local/etc# grep -v '^ *$#.*$\?$' dovecot-sql.conf driver = mysql connect = host=localhost dbname=xxx user=mailuser password=xxx default_pass_scheme = MD5-CRYPT user_query = SELECT maildir, 5000 AS uid, 5000 AS gid, CONCAT('*:storage=', quota, 'B') AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1' password_query = SELECT username as user, password, '/var/vmail/%d/%n' as userdb_home, 'maildir:/var/vmail/%d/%n' as userdb_mail, 5000 as userdb_uid, 5000 as userdb_gid FROM mailbox WHERE username = '%u' AND active = '1' charged:/usr/local/etc# charged:/usr/local/etc# dpkg -l | grep postfix ii postfix 2.5.5-1.1 High-performance mail transport agent ii postfix-mysql 2.5.5-1.1 MySQL map support for Postfix charged:/usr/local/etc# Regards, Shayne Jellesma Network Administrator / ICT Support St Martins Lutheran College Web: <http://www.stmartins.sa.edu.au> http://www.stmartins.sa.edu.au Phone: (08) 87 251 430 Skype: shayne.jellesma.smlc

[Dovecot] Problems with Outlook clients after a migration
by Joseba Torre 28 May '10

28 May '10

Hi, I'm doing the final tests before I migrate my 10000 users from RHEL 4 + dovecot 1.1.20 to RHEL5 + dovecot 1.2.11, and I'm having some serious problems with outlook 2007 clients disconnecting very often. In dovecot's log I see lot of connects and disconnects from these clients (as oposed to my kmail, that just connects once when I come in and disconnects when I shut it off). After unchecking the "chek every X minutes" thing in outlook I get fewer of those -while functionality remains-, but the main problem still persists: every now and then (more or less 30 mins), the client disconnects, and sometimes the client goes offline. This didn't happen with my previous setup. I use the outlook-idle workaround, but it doesn't seem to make any difference. Any ideas?

[Dovecot] Cannot Access Inbox
by robertober 27 May '10

27 May '10

Hello Folks, Yesterday while messing around with procmail for SpamAssassin I had my IMAP client open and it lost it's ability to see my Inbox except for two messages. I tried another IMAP client and no success. I can see all other directories such as sent and the ones I have made. The mbox file is there and catable/grepable. I even made a new one. I can read a test account Inbox from the same server with my usual client. Also my small number of other users appear to be using pop3 as normal. Tried so far: * Multiple clients including pop3. * Removed spamd and procmail stuff. * Various permissions. * New mbox. * Restart everything, although I am not sure I rebooted the server last night. * Searched for lock files that may need to be deleted. * Googled. Server setup: * Mandriva Linux 2009.1 * Dovecot 1.1.13 * Postfix 2.5.6 The mailbox in question is my business and some personal email so I would greatly appreciate any help towards fixing this issue. I am self-employed and largely out of business without my email. Thanks, Robert A. Ober

[Dovecot] symlinking maildirs
by Phil Howard 27 May '10

27 May '10

I have some emails that I think are in the Postfix delivery queue going to Dovecot, but didn't get mapped to their alias (because I didn't have all the alias entries in when they were queued). I'm wondering if this trick would work. I have the mail being delivered to /home/mail/%Ld/%Ln/mail and am wondering if I could make a symlink at /home/mail/example.com/foo -> bar and add a dummy password for foo(a)example.com and have that mail trying to go to foo(a)example.com really go to bar@example and make a successful delivery (it is soft bouncing right now).

[Dovecot] Dovecot access imap folder via POP3
by Vincze Janos Istvan 27 May '10

27 May '10

Dear All, I use postfix and dovecot (1.1.11) combo with maildir format. I would have a question about dovecot config. Can I confiugre dovecot to download mails from IMAP folders via POP3? Now, mails can be downloaded only from .INBOX. My dovecot.conf file: .... mail_location = maildir:/home/vmail/%d/%n/Maildir namespace private { separator = . prefix = INBOX. #location = mail_location = maildir:/home/vmail/%d/%n/Maildir inbox = yes #hidden = yes } mail_privileged_group = mail .... Thank you for any help, Janos, Vincze

[Dovecot] Overly long email of miscellaneous Dovecot migration questions
by Mark Moseley 27 May '10

27 May '10

Hello to the list! I've been asked to spec out the feasibility and, if feasible, plan a migration from Courier to Dovecot for both POP3 and IMAP for about 4 million mailboxes. I've been trying to absorb all the dovecot-related info I could over the past couple of weeks from the docs and from the list and I'm sure that I've muddled at least some of it, so apologies in advance if I make grossly incorrect assumptions. BTW, sorry for the giant email but I've got a bunch of questions. This is the sort of overly wordy email that makes my eyes glaze over in mailing lists. But I've got things configured to where (I think) everything will 'just work' if we migrate (barring running POP3 mailbox conversions), so I'm not looking for configuration help, just gotchas and assumption-checking mostly. Me breaking 4 million mailboxes isn't really a good move for my job security ;) * Since Dovecot 2.0 seems like it's just around the corner, that's all I've been testing, and indeed all I've even looked at. * This is a pretty fantastic piece of software. I love the neat little details that make admins' lives easier, e.g. how easy it is to use multiple SSL certs in the same server. That made me smile. I hadn't looked at dovecot in a number of years, so I was really impressed at the full feature set. It's been a while since I've played with a new server application that I've enjoyed this much. * Background: All of our mail is stored on NFS and will be for the foreseeable future, all in maildir format. Courier POP3/IMAP runs on load balanced Linux servers, so clients will be hitting multiple servers, though stickiness based on client IP address is currently done. Webmail as well is done on top of a local Courier IMAP server accessing the same NFS servers but on an entirely different pool of servers. All authentication is done against SQL. Courier has been very, very good to us over the past 9 years, but our NFS servers (12 Netapps) are unfortunately being beaten to death. We've got lots of users with thousands of emails in their inbox (i.e. in ./Maildir/cur/ alone) and I've seen plenty of mailboxes with 10's of thousands in their inbox and I've even seen some really scary ones approaching 100k emails just in cur/. Thanks to an endless cycle of industry raising mailbox limits, we actually have to support this (though not so much the 100k message ones, at least). * Our #1 main motivation for looking Dovecot is relief for our currently overtaxed NFS servers, mostly in the form of the index files. Benchmarking dovecot looks great, even with the index files in the maildir. I know the cool thing to do would be to move the index files to a separate NFS server running entirely on SSDs for the fastest accesses possible. Building a separate index NFS cluster obviously adds complexity and performance with the index files in the maildir seems pretty great already. But I also know that real life often makes assumptions made during benchmarks look very foolish. My inclination is to try things out with the indexes in the maildir directory (and then start looking at moving to a dedicated NFS server for the indexes in a subsequent phase) but I don't want to regret that choice later. Anybody with large-scale NFS maildir stores have any advice either way? * Exim: We currently deliver all of our mail via Exim on separate servers. Our POP3/IMAP servers only do POP3/IMAP and the Exim mail servers delivering to maildirs only do Exim. From what I've seen in the docs and various threads, from what I can gather, the best thing to do in that case would be to use Exim's built-in maildir handling, instead of using 'deliver'. That would be my preference anyway, but I wanted to make sure I didn't misinterpret things. * Any problems running Courier POP3 and Dovecot IMAP for a while, possibly Courier IMAP and Dovecot IMAP concurrently?: Since migrating POP mailboxes is going to be a mighty task, our gameplan would probably be to start migrating *just* IMAP services at first and likely on just a few servers at a time. Being load balanced, there are several scenarios where a user could theoretically access a mailbox on different servers and therefore end up hitting dovecot at one point in time and then later hitting courier or vice versa. Or they could use IMAP from one location and POP3 (during the span of time before we migrated our POP3 services) from another. I've not yet seen any side effects from switching mail servers like that (though I'm aware of what would happen if both dovecot and courier *POP3* were in service at the same time -- redownloaded mail, bleh). Has anyone seen otherwise? I'm not worried as much by the 0.1% of IMAP users who might be using advanced features but rather the other 99.9% who are using it pretty vanilla-ishly. * Union mailboxes: I'm pretty sure in a fairly recent thread that Timo said that something like a 'union' mailbox (at least with maildir) wasn't possible. I tried messing with multiple 'private' namespaces (i.e. a namespace called "ARCHIVE" with a "location" different than the INBOX location, ideally placed on slower but denser NFS servers) but even with 'hidden=no' and 'list=yes', only the main INBOX folders would show up, so I'm guessing that's not going to work. That would be a killer feature, to be able to serve an alternate namespace that would show up in a mail client's subscribable list that could be on slower storage than the main inbox (though I'm not sure a mail client can even handle multiple namespaces). * Any problems with keeping only quota limits in db and not current quota numbers? Our limits come out of a SQL table but the current counts just live in the maildir file. Trying to update quota counts in SQL for 4 million mailboxes is a non-starter for us at this point. >From what I've done, dovecot seems pretty happy to maintain the quota using the 'maildir' quota plugin but let it be overridden by the userdb lookup. So I think I'm fine on that count, but I'd love to hear from anyone knowing of extreme gotchas doing it that way. * Any problem with leaving the namespace in "Courier compatibility" mode? I.e. in namespace 'private', leaving "prefix = INBOX.". With 4 million mailboxes, FAQs all over the place, and support reps trained in a particular way of doing things in IMAP, it'd be hellish to try to change the prefix (I know I could leave the courier namespace around with 'hidden=yes' but retraining support staff is perhaps better left to phase #2). Do I lose anything besides tidiness by not changing it to "prefix =" as if I was deploying dovecot from scratch? Does it hurt performance in any significant way? Benchmarking doesn't look any different, so I'm guessing not. * One thing that threw me and might be good for a FAQ (unless it was just me misconfiguring things) was when I started playing with putting the index files in an alternate location. I was utterly perplexed why it'd create the directories for the indexes but they'd be empty. Based on their location and names when they're in the maildir, I was just looking for the same dovecot.index* files right in the alternate directory. It wasn't till I started strace'ing that I noticed that the index files were indeed getting created but in a subdirectory called .INBOX (and with me just doing 'ls'). * The courier-dovecot-migrate.pl does a fine job at converting our POP3 mailboxes. We'll definitely be doing a mass run of it across all of our mailboxes. But with this many mailboxes, there's no way to get around the time lag between the script getting run and new mail showing up. Which means that there'll be some number of new messages that will re-download in POP3 when the switchover to Dovecot POP3 is done. To keep from getting too many complaints from customers, I'm thinking that I might have to write a wrapper script to do something like compare the mtime of ./Maildir/new/ against dovecot-uidlist and overwrite if ./Maildir/new/ is newer or perhaps see if the mtime of courierpop3dsizelist is newer than dovecot-uidlist and only if that's the case execute the conversion script with --overwrite. Considering we get between 500-2000 POP3 logins/sec, running any script after a POP3 login terrifies me--even a 6 line bash script. Anybody have any opinions to share on that? With a pooled architecture, it's near impossible to only have some mailboxes hit Courier and some hit Dovecot and keep slowly incrementing. At best my available units of increments to migrate are a few thousand at a time and more realistically 10-20k at a time. If we're going to have to live with users complaining about a one-time redownload of just post-conversion mail, I'll need to get started convincing the higher-ups that that's life. A big thanks to anyone who even actually reads this entire tedious email and a tremendous thanks to anyone who actually replies to any of it!

[Dovecot] listescape und sieve
by Heiko Schlittermann 27 May '10

27 May '10

Hello, bug or feature? I'm using Dovecot 1.2.11. And because of a migration projekt I'm tempted to use the listescape plugin. If I understood well, it plugin { escape_char = "%" } should change the escape character to %. But it doesnt. Bug or feature? But more important: # sieve fileinto "a.b"; does not work as expected - the folder is visible as "a.b" in a normal imap client - because of the listescape plugin. # sieve fileinto "a\\2eb"; works. But the user won't understand this. Any ideas?

[Dovecot] mdbox: Is there any more info on the "cleanup" step? (Dovecot 2.0beta5)
by William Blunn 26 May '10

26 May '10

The wiki page which mentions mdbox talks about a "cleanup" step for mdbox: : The space is later freed in "cleanup" step. This may be done : automatically within the session or later in a nightly cronjob when : there's less disk I/O. The cleanup first finds all files that have : refcount=0 mails. Then it goes through each file and copies the : refcount>0 mails to other dbox files (to the same files as where newly : saved messages would also go), updates the map index and finally : deletes the original file. So there is never any overwriting or file : truncation. I was wondering if there was any code to actually do this, or any command-line tools (and if either of those where they might be), or whether it was just design musings at the minute. Regards, Bill

[Dovecot] mdbox: What format is the file "storage/dovecot.map.index" in? (Dovecot 2.0beta5)
by William Blunn 26 May '10

26 May '10

I am looking at "mdbox" under Dovecot 2.0beta5. Looking at the documentation for "mdbox" I saw that we had a directory "storage" containing files "m.#" where "#" is an integer and a map file ("dovecot.map.index"). I think I expected the map file to be a plain text file with one record per line, but in fact it appears to contain binary data. According to the wiki ( http://wiki.dovecot.org/MailboxFormat/dbox ) the records go as: - map_uid: Unique growing 32 bit number for the message. - refcount: 16 bit reference counter for this message. Each time the message is copied the refcount is increased. - file_id: File number containing the message. For example if file_id=5, the message is in file m.5. - offset: Offset to message within the file. - size: Space used by the message in the file, including all metadata. The map file I have here is 1688 bytes in size (and I think there are 64 messages stored). Prime factors of 1688 are 2^3 x 211, so I think it is something other than just a straight array of fixed-size structures. Still, I can always look at the source if I really want to know :-) Regards, Bill

But the whole point of the code is to get number of affected rows for previous UPDATE, so that if there is no quota row for user, the quota gets recalculated. This fixed it for my tests: http://hg.dovecot.org/dovecot-2.0/rev/0c15a760dab8

[Dovecot] newbie question about shared folders
by Tom Lieuallen 26 May '10

26 May '10

I'm preparing to move our site to dovecot 1.2.11 and have a question about shared folders. We're currently using UW imap's mbx mailboxes for shared folders. We accomplish the sharing by use of file system permissions and ACLs. I notice that dovecot's method of sharing is more based on IMAP ACLs and apparently file system permissions are useful, but not necessary. On the main dovecot page, it says: "Dovecot allows mailboxes and their indexes to be modified by multiple computers at the same time..." So, my question is whether I need to use the dovecot imap sharing namespace in order to safely share imap folders, or whether I can just use file system permissions as we have been using? My biggest concern is safe concurrent access to the shared folders, which I'm planning to implent with mbox files for now. thank you Tom Lieuallen Oregon State University College of Engineering

[Dovecot] Busy looping of 2.0Beta4 on NetBSD-current
by Scott Ellis 26 May '10

26 May '10

I built and install Dovecot 2.0Beta4 on my NetBSD/amd64-current system, and am seeing the user-owned imap processes busy-looping. In Dovecot 1.2.x (and 1.x and 0.x..) I force ionotify and ioloop to kqueue, so I suspected that was the problem. Turns out it's not: Using poll or none also causes the same problem. This did not happen in 1.2.8 (didn't try anything later than that). After a quick visit to gdb, I added some i_debug() statements in ioloop-kqueue.c (when I had that as the notify and loop method) which showed that the loop was in io_loop_handler_run() . I haven't done any similar debugging for the other ioloop methods, but a quick look at the 2.0 changelog for those files doesn't raise any immediate alarms. Any ideas what to look for here? Timo, any ideas? 1.2.x worked perfectly so it's something "new" in 2.0. ScottE

[Dovecot] quota and lazy_expunge plugins both used: quotas go wrong with lazy_expunge'd mails
by Baptiste Malguy 26 May '10

26 May '10

Hello, I may have missed a point, but I could have found an issue between plugins quota and lazy_expunge. I have noticed that the "lazy_expunge"d mails are counted as part of the quota, while the documentation says it should not be. I have first tried to find out if this was a configuration mistake somewhere. Notably, you can notice that the expunged mails are in directory ~/expunged while the usual mail is in ~/Maildir : expunged mails are not in a subdirectory of ~/Maildir (this was just to make sure there were no side effect with this). I have deleted some expunged mails to be sure : at its next cycle, the file ~/Maildir/maildirsize contained expected value. So yes, I do know expunged mails in the expunged directory are counted (size, number of mails). So I've taken a look at the source code, adding some i_info(...) at different places of the quota and lazy_expunge plugins. >From the source code reading session, I understand that : 1. In src/lazy-expunge/lazy-expunge-plugin.c 1.1. lazy_expunge_mail_storage_init() sets the expunged mails namespace flag with NAMESPACE_FLAG_NOQUOTA 1.2. lazy_expunge_mail_storage_init() is called by lazy_expunge_mail_storage_created() 1.3. lazy_expunge_mail_storage_created() is part of the callback list hook_mail_storage_create 2. In src/plugins/quota/quota-storage.c: 2.1. The only place in the whole dovecot source code where NAMESPACE_FLAG_NOQUOTA is checked is in function quota_mailbox_list_created() 3. In src/plugins/quota/quota-plugin.c: 3.1 quota_plugin_init() add quota_mailbox_list_created() to the callback list hook_mailbox_list_created. >From my observations : - Callback functions in quota_mailbox_list_created are called _before_ callback functions in hook_mail_storage_create. - This observation led me to move the piece of code that sets NAMESPACE_FLAG_NOQUOTA from lazy_expunge_mail_storage_init() to lazy_expunge_mail_storage_created(). - But there, lazy_expunge_mail_storage_created() is called after quota_mail_storage_created() because names of the library files are lib10_quota_plugin.so and lib02_lazy_expunge_plugin.so. - There I have also learnt that callback functions of the same list are called in the reverse order compared to the library filenames. So see if my observations were right, I have renamed lib10_quota_plugin.so to lib01_quota_plugin.so, then it worked. But I doubt this is the right way to fix it. This also reverses the order other callbacks between the two plugins are called, which migh not be expected at all. I'm not event sure moving some code from lazy_expunge_mail_storage_init() to lazy_expunge_mail_storage_created() was right : I've improvized the reading the source code and do not understand the whole logic, so I suppose this could break something else. Timo, what do you propose ? Thanks for your great software. -- Baptiste MALGUY PGP fingerprint: 49B0 4F6E 4AA8 B149 B2DF 9267 0F65 6C1C C473 6EC2

[Dovecot] Zlib plugin dovecot 2.0beta4
by Alex Baule 26 May '10

26 May '10

Hi Timo... I made the plugin like you say. The header part is saved by dovecot, with o_stream_send , and the body with my function. This implementation, works fine. But i need to get / change some values to create the "link" from header to body. When a email is saved, have the S an W flags, that is the size of email. There is a way to increase this Flags ? I need to put one more line in the header, to have some link to body. To Increase the S Flag i increase the ostream.offset, but the W is based in the offset from istream, that's right ? There is a way to do this without rewrite the read function !? Exemple, when the email is moved from tmp to cur.

[Dovecot] proxy user wildcard
by Martin Ott 26 May '10

26 May '10

Hi, I'd like to try dovecot as a imapproxy in front of a webmailer. Authentication should be done by the main dovecot-imapserver. It works if I specify the user in passdb passwd-file: user2::0:0::::proxy=yes host=[ip-address] ssl=any-cert starttls=yes nopassword=y Is there some kind of catch-all function to pass all users to the main dovecot-imapserver without knowing the valid users? dovecot: 1.2.9 thx Martin

[Dovecot] Plugins and message file access
by Reinaldo Matukuma 26 May '10

26 May '10

Hello. I need to know how I can get the final message file name inside a plugin like the zlib 2.0 plugin. I saw another threads about zlib plugin, but don't see no one asking about this. My interest is to use the message's file name in a specific function that will add some lines on it and, after that, calculate a md5 hash of the modified file. As the size flags will not correspond to the effective message size/vsize, then I could change the flags using the filename too, right? This is my first approach. But... There are another way to do this directly on message been received by the plugin, like pre-allocating the size/vsize flags? I cannot simply to pass the extra text directly on the message being received because I need to do some extra validations over the full content of the message before add my data on the message.

[Dovecot] corrupted transaction log errors causing users mail to disappear temporarily
by Jordan Tardif 26 May '10

26 May '10

So Ive been looking into some problems with users reporting their mail goes missing for a second but then re-apears very soon after. I have tracked it down to happening at the same time these appear in the logs. Seems the transaction logs is getting corrupted somehow and then rebuilding itself (which works fine). The problem is while its re-builing the users think all of their mail is gone. May 3 09:35:52 mailmachine dovecot: IMAP(test(a)domain.com): Corrupted transaction log file usershomedir/Maildir/dovecot.index.log seq 3: Invalid transaction log size (32708 vs 32840): usershomedir/Maildir/dovecot.index.log (sync_offset=32708) We are using load balanced servers and data/index's are stored in their home dir's over nfs. All my config details and nfs options are below. We are currently balancing based on source address so most of the time users imap/pop processes should stick to one machine as much as possible. Does anyone know of a way to rid of this problem, or at least make it so dovecot just returns a server error to the imap/pop client instead of showing them a blank index? #nfs options defaults,intr,vers=3,bg,rsize=8192,wsize=8192,proto=udp 0 0 # 1.2.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.29.2-xenon-mail-ipv6-grsec x86_64 Debian 5.0.1 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap pop3 listen(default): *:143 listen(imap): *:143 listen(pop3): *:110 disable_plaintext_auth: no login_dir: /usr/var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_user: dhmail login_process_per_connection: no login_processes_count: 150 login_max_processes_count: 1000 login_max_connections: 3000 max_mail_processes: 2500 mail_max_userip_connections: 7 first_valid_uid: 100 mail_privileged_group: mail mail_location: maildir:~/Maildir mmap_disable: yes mail_nfs_index: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): UID%u-%v -- Jordan Tardif DreamHost

[Dovecot] Where should I define mail_uid for deliver LDA?
by Alex 26 May '10

26 May '10

Hello folks I'm trying to use Dovecot deliver LDA instead Postfix virtual LDA The last road block I have to resolve is to define mail_uid, becaus dovecot.err log has these error messages: May 04 14:57:19 deliver(user1(a)some_domain.com): Error: User user1(a)some_domain.com is missing UID (set mail_uid) May 04 14:57:19 deliver(user2(a)some_domain.com): Error: User user2(a)some_domain.com is missing UID (set mail_uid) May 04 14:57:25 deliver(user3(a)some_domain.com): Error: User user3(a)some_domain.com is missing UID (set mail_uid) Where exactly should I define mail_uid? Somewhere in Dovecot dovecot.conf file? I tried to set mail_uid in dovecot-sql.conf in user_query as follows: user_query = SELECT maildir as mail, 51 as userdb_uid, 51 as userdb_gid, 51 as mail_uid FROM dovecot_email_maps WHERE email = '%u' But this apparently doesn't provide that mail_uid as I expected. Could somebody please enlighten me on this issue. Thank you in advance, Alex

[Dovecot] mixture of virtual and plain users
by Kapetanakis Giannis 26 May '10

26 May '10

Hi, I have a mail server (postfix/dovecot) running so far with normal local /etc/passwd users for domain example.com. mail_location = maildir:~/Maildir passdb pam { } userdb passwd { } Is it possible to add virtual domains/users to my setup without changing example.com to a virtual domain? I can do the postfix part with http://www.postfix.org/VIRTUAL_README.html#virtual_mailbox but I'm not sure if I can mix dovecot (IMAP and maybe smtp auth) for both local and virtual users. Any hint would be appreciated. best regards, Giannis

[Dovecot] libdovecot not referencing libiconv

[Dovecot] Bug in zlib Plugin (2.0)
by Alex Baule 26 May '10

26 May '10

Hello everyone..... I Made some tests in zlib plugin, and in ostream file (ostream-zlib.c) in o_stream_zlib_sendv function, have it: stream->ostream.offset += bytes; In struct mail_save_context, have saved_physical_size and it can be updated, acording with the observation. /* if non-zero, overrides the physical size that should be saved. for example when using zlib plugin, this would contain the mail's uncompressed size. */ uoff_t saved_physical_size; in file zlib-plugin.c in zlib_mail_save_compress_finish function, have it: ctx->saved_physical_size = ctx->output->offset; It's a update to offset (the size of email) in zlib, but if you update this value with a new number, the W flag in email is NOT updated. This is the original file, without update the or increase offset. 1273155226.M512158P16310.brc,S=435,W=390:2,S This is the file updated with 5000b more. 1273155226.M512158P16310.brc,S=5435,W=390:2,S The S is updated, but W not. OK, this not matter in zlib plugin, because the physical size is the email uncompressed, but if you use the zlib as example, and you use this value (saved_physical_size) to update your saved email size, it can't update the W flag, and the email will not be open, because the W size is wrong.

[Dovecot] A few questions on shared folders
by Michael Durket 26 May '10

26 May '10

I'm looking at the possibility of using shared folders to solve a particular problem for my employer and I have a few questions: 1) Can shared folders be in mbox format while allowing the user's mail to be in maildir format? (I think the answer is yes, but wanted to check). 2) What version of dovecot should I be running in order to support shared folders? 3) Is there a good overview document that people could recommend I read that describes how best to set up shared folders under dovecot (and perhaps also gives an overview of shared folder usage in IMAP mail clients in general)? Thanks very much, Michael Durket

[Dovecot] STARTTLS does not seem to work
by Phil Howard 26 May '10

26 May '10

I believe I have the configuration set to use START TLS on IMAP4 (143) and POP3 (110) ports. However, it does not seem to be working. Yet "STARTTLS" is listed as a capability (which tells me I probably do have it configured right). In the session below, 172.30.0.24 is the mail server I'm putting up. 64.26.60.229 is an outside mail service. A similar thing happens on POP3. The always-SSL/TLS ports (993 and 995) are working. There's very little documentation matching "starttls". ======================================================================== altair/phil /home/phil 162> telnet 172.30.0.24 143 Trying 172.30.0.24...

[Dovecot] config file includes
by Tim Traver 26 May '10

26 May '10

Hi all, ok, I couldn't quite find this in any of the documentation, so I figured I would ask here. In preparation to move to version 2.0 to take advantage of the mutiple IP and SSL cert options that are coming, it would be really nice to be able to include other config files in the main config file, so that I don't have to edit the main config in order to add new IP addresses or certs... Does dovecot currently have the ability to include another config file when it is parsing the main config??? If not, is that something that we can put on the wish list? Thanks, Tim.

[Dovecot] Problems with the fs-quota plugin on delivery stage
by Kostik 25 May '10

25 May '10

Hi All! Just noticed a strange behavior of the FS quota plugin on delivery stage. We use group FS quotas via NFS. And quota-tool says: --- Disk quotas for group #5751796 (gid 5751796): Filesystem blocks quota limit grace nfse:/export 1276 10240 10240 --- I run: --- cat ./test.eml | /usr/local/libexec/dovecot/deliver -e -n -d xxxx(a)xxxxx.xxxx --- and get: --- Quota exceeded (mailbox for user is full) --- But ./test.eml is 7088147 bytes and it is not above the quota. dovecot debug log is: --- May 12 20:01:46 dovecot: deliver(xxxx(a)xxxxx.xxxx): fs quota block device = nfse:/export May 12 20:01:46 dovecot: deliver(xxxx(a)xxxxx.xxxx): fs quota mount point = /mount/m5 May 12 20:01:47 dovecot: deliver(xxxx(a)xxxxx.xxxx): quota-fs: host=nfse, path=/export, gid=5751796, bytes May 12 20:01:47 dovecot: deliver(xxxx(a)xxxxx.xxxx): quota-fs: gid=5751796, value=8409088, limit=10485760, active=1 May 12 20:01:47 dovecot: deliver(xxxx(a)xxxxx.xxxx): from=<xxxx(a)xxxxx.xxxx>, msgid=<4BEA4744.1040701@xxxx@xxxxx.xxxx>: save failed to INBOX: Quota exceeded (mailbox for user is full) --- It seems that "value=8409088, limit=10485760" shows that the quota is no problem, but "save failed". If I become that user, then no problems. I can copy ./test.eml without problems. Now quota-tool says: --- Filesystem blocks quota limit grace nfse:/export 8212 10240 10240 --- If I try to copy again(over quota), then honestly get: --- cp: closing `./test2.msg': Disk quota exceeded --- If I switch off quota plugin on dovecot.conf (LDA specific settings), then: - 1. The first delivery is without error, but the INBOX is corrupted(last msg is clipped) but quota-tool show only 3300 blocks used (quota is 10240 blocks). - 2. Following delivery big msgs (over quoted) ends with an error: "Not enough disk space" (this is correct, because the quota is really ended) - 3. Following delivery small msgs (above quoted) ends well, msgs are delivered (used 3304 blocks and etc.) Our setup: -- slackware 11.0, x86_32 -- linux 2.6.31.6 -- dovecot 1.2.11 -- mailbox(not maildir) via NFS storage. Please, tell me where to start looking for the problem? =kostik

[Dovecot] (1.2.11): Confused about shared/public folders
by Denny Schierz 25 May '10

25 May '10

hi, i red several hours a lot of documentation (wiki, Blogs, lists ...) how to get public folders. Under cyrus it is very easy. Create a mbox on the top with cyradm and some acls. Nothing more ... All i want is: public/info public/group/internal public/foo public/foo/bla on info, everybody can read on group/internal - only group has full access to internal public/foo/bla - read write for everyone The flags (seen, ...) is stored for all. The wiki entries are to old or mixing several things and are not clear, what I should do, to get it working. my config: dovecot.conf mail_location = maildir:/imap/domain/%1n/%n:INDEX=/imap/indexes/domain/% 1n/%n namespace private { separator = / prefix = inbox = yes } #namespace shared { # separator = / # prefix = shared/%%u/ # location = maildir:/imap/shared/domain/%1n/% n:INDEX=mbox:/imap/shared/domain/%1n/%n # subscriptions = no # list = yes #} namespace public { separator = / prefix = public/ location = maildir:/imap/shared/domain subscriptions = no list = yes } mail_uid = vmail mail_gid = vmail mail_privileged_group = vmail protocol imap { login_executable = /usr/local/dovecot/dovecot/libexec/dovecot/imap-login mail_executable = /usr/local/dovecot/dovecot/libexec/dovecot/imap mail_plugin_dir = /usr/local/dovecot/dovecot/lib/dovecot/imap/ mail_plugins = quota imap_quota imap_idle_notify_interval = 120 fsync_disable = yes mail_plugins = quota imap_quota acl imap_client_workarounds = outlook-idle netscape-eoh } plugin { acl = vfile acl_shared_dict = file:/imap/rbg/acl/shared-mailboxes.db acl = vfile:/imap/rbg/acl/dovecot-acls } I wasn't able to use under plugins imap_acl, cause of errors: open(/usr/local/dovecot/dovecot/lib/dovecot/imap//lib02_imap_acl_plugin.so) failed: ld.so.1: imap: fatal: relocation error: file /usr/local/dovecot/dovecot/lib/dovecot/imap//lib02_imap_acl_plugin.so: symbol acl_mailbox_right_lookup: referenced symbol not found Couldn't load required plugins Error: imap dump-capability process returned 89 Fatal: Invalid configuration in /usr/local/dovecot/1.2.11/etc/dovecot.conf System is Solaris10, build by my self with Sieve Patches. After changing to "acl" only, DoveCot starts. So, i can see in Roundcube (webmail) the folder Public (or shared, from the above example) but nothing more. Do i need symlinks, or what I have to do after create the folder + permissions? cu denny

[Dovecot] order of variable modifiers
by Phil Howard 25 May '10

25 May '10

I'd like to have a variable substitute take the domain name part, lower case it, MD5 it, and take a 2-character substring of that. Would that be like %2MLd ? The documentation on the H hash modifier described reversing with R, but expresses it at %3RHu which seems to me like it would be reversing the hash result rather than the user string. I'm undecided about MD5 vs. hash, and could go either way. But I was thinking: mail_location = /data/mail/%2MLd/%Ld/%2MLn/%Ln

[Dovecot] per domain quota
by alex 25 May '10

25 May '10

Hi I'am using dovecot with quota_rule stored in mysql user table, and quota usage stored in mysql dict ###### Quota ############# dict { quotadict = mysql:/usr/local/etc/dovecot-quota.conf } plugin { quota = dict:user::proxy::quotadict quota_rule2 = Trash:storage=10%% quota_rule3 = Sent:ignore #quota_rule = *:storage=10M } ################################### Everything works as expected, but I have some inconveniences for domains with large number of mailboxes. Allocating and maintain quota to every account it's a hard job. I just want to implement some flexibility for this situations (ex the first enforcement to be the user quota and the second to be the domain quota). Is there a way to implement such thing in dovecot and what are the adjustments that I need to do. Regards Alex

[Dovecot] v2.0.beta5 released
by Timo Sirainen 25 May '10

25 May '10

http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta5.tar.gz http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta5.tar.gz.sig Sorry for being so quiet recently. Unfortunately I think it's still going to last a while longer. I'll be in Italy for next two weeks and immediately after that I'll move to Portugal. I'll probably write something about that later to blog. I had hoped that this beta5 would be almost the same as RC1, but I didn't have time to put everything there yet, and thought beta4 is way too old already. The few things that should still be done: - Change expire-tool to be a plugin for doveadm expunge command - doveadm mailbox * commands should use UTF-8 for mailbox names, not mUTF-7 (and add -7, -8 parameters to switch between them) - THREAD command seems to be crashing - some other bugfixes Some of the changes since beta4: - default_login_user is now "dovenull". You should create this user. - imap, pop3 -u <user> now does userdb lookup + changes privileges if necessary, so it's much easier to start imap/pop3 session for a specific user from command line - doveadm has all kinds of new commands and changes - PostgreSQL supports now multiple connections to backend. Also supports load-balancing / HA by specifying multiple host parameters. MySQL and PostgreSQL now share the same code for that. - probably lots of other things I can't think of right now. h

[Dovecot] about acl
by Yavuz Maşlak 25 May '10

25 May '10

I use dovecot, vpopmail. I wish to restrict a mail user's login to its mailbox according to its ip address. I don't wish other users to be affected . Namely, for instance, abc(a)domain.com can login to its mailbox from a few specific ip addresses but the same user will not able to login from anywhere. Meanwhile normally other mail users can login to their mailboxes from all ip addresses. How can I do that with dovecot acl ? any advice.

[Dovecot] suggestion
by Andreas Schulze 25 May '10

25 May '10

hello, dovecot2 implements "!include conf.d/*.conf" to build the configuration from multiple configfiles. So the settings for pop3, imap or lmtp may stay in different files. unfortunately the "protocol = " does not allow a += logic to enables or disable inet listeners. It would be nice to have protocols += imap in conf.d/imap.conf and protocols += managesieve in conf.d/managesieve.conf This would make the include feature more consistent... or is it already possible ? -- Andreas Schulze Internetdienste | P532 DATEV eG 90329 Nürnberg | Telefon +49 911 319-0 | Telefax +49 911 319-3196 E-Mail info @datev.de | Internet www.datev.de Sitz: 90429 Nürnberg, Paumgartnerstr. 6-14 | Registergericht Nürnberg, GenReg Nr.70 Vorstand Prof. Dieter Kempf (Vorsitzender) Dipl.-Kfm.

[Dovecot] List shared folders
by Marcio Merlone 25 May '10

25 May '10

Good morning! I run an imap-only Ubuntu 8.04 mail server with dovecot 1.2 and pam_ldap, so all my users are posix users. No virtual user or domain, no sql so far. I am setting up shared folders with "namespace shared". I got no errors upon restarting the service, but I get no shared folders listing. As per the wiki http://wiki.dovecot.org/SharedMailboxes/Shared I can use a bdb file or sql connection to keep the listing. But when I use a single bdb file like: plugin { acl_shared_dict = file:/var/lib/dovecot/shared-mailboxes.db } everytime a user logs in, this file get its ownership to the user with 0600 mode. I could use an sql dictionary, but since I dont have any sql params on my configs I am not sure where to store connection params like user, password and host for database. Can anybody help me with that? My goal is to allow my users to shared selected folders with other users, hope to be in the right path. Thanks and regards. -- Marcio Merlone

[Dovecot] Setting up ACL for IMAP
by Andrés Gattinoni 25 May '10

25 May '10

Hi guys, I just suscribed cause I'm trying to do something which I'm not sure how. I need to prevent some accounts from deleting there emails. >From what I've seen [0] this could be achieved by using ACL. My first question is, is this right? Is there a way to achieve the same using POP3? I tried setting up ACL using the info at the Wiki [1], but it's not working. What I've seen is that when I put: protocol imap { mail_plugins = acl imap_acl } I get the following error: May 14 14:54:52 mail dovecot: SIGHUP received - reloading configuration May 14 14:54:52 mail dovecot: imap dump-capability: Couldn't read capability (got 0 bytes) May 14 14:54:52 mail dovecot: Invalid configuration, keeping old one May 14 14:54:52 mail dovecot: child 32301 (unknown) returned error 82 (Internal logging error) Looking on the internet I found out that I don't have the imap_acl lib shared object.

[Dovecot] SSL Bug
by Matthew Sackman 25 May '10

25 May '10

Hi, After many hours of testing, I've finally tracked down the issue I have been having with dovecot's SSL support. The problem is that the SSL certs result in "TLS handshaking: SSL_accept() syscall failed: Connection reset by peer" errors *if the certificate granted is not granted for client use*. For servers, I normally generate SSL certificates specifically for servers: [ server_ca_extensions ] basicConstraints = CA:false keyUsage = keyEncipherment extendedKeyUsage = 1.3.6.1.5.5.7.3.1 If you just do that, then the SSL certificate doesn't work in dovecot (it will work fine in Apache, or Postfix etc etc). You also need the certificate to be valide for client side work: [ client_and_server_ca_extensions ] basicConstraints = CA:false keyUsage = digitalSignature, keyEncipherment extendedKeyUsage = 1.3.6.1.5.5.7.3.2, 1.3.6.1.5.5.7.3.1 I believe this is a fault with Dovecot. This is with the Debian package for Dovecot 1.2.11 (Version: 1:1.2.11-1). The default self-signed certificate the Debian post-install script generates pops out a certificate that is valid for everything, which is why it works by default out of the box. Matthew

[Dovecot] dovecot/deliver ... Can't open log file /var/log/dovecot/error.log: Permission denied
by Phil Howard 24 May '10

24 May '10

I'm getting this ... May 10 12:45:01 eth0 postfix/local[3416]: A788D685F7: to=< xxxxxxxx(a)xxxxxxxx.net>, relay=local, delay=13, delays=13/0/0/0.03, dsn=4.3.0, status=deferred (temporary failure. Command output: Can't open log file /var/log/dovecot/error.log: Permission denied ) So I'm looking at http://wiki.dovecot.org/LDA to see what I can do about it. I would have hoped some comments in the example config file would have mentioned this and suggested a default practice solution. Is this something few people or many people encounter (among those using dovecot/deliver from Postfix)? If I do as the wiki describes and make separate log files for dovecot/deliver to use, do I just make them owned by Postfix? It would seem to me a different directory might be more helpful (absent log files could be created by having the directory permissions. I'm also thinking in terms of log rotations, too ... and I prefer to do log rotations by date stamping rather than pushing sequence numbers (the legacy log rotation). Any chance there are %-style variables I can use in log file/path names to make log files automatically named by the date (and maybe time) ... kind of like in a shell script I would do: `date +/path/to/tree/%Y/%m/%d.log` or such.

[Dovecot] Thunderbird very slow startup, 1.2.11, mbox, postfix local delivery to /var/mail
by Stan Hoeppner 22 May '10

22 May '10

I've Google'd to exhaustion and can't seem to find an answer to my problem. I'm not sure if the problem is TBird 3 or my Dovecot setup. The basic problem is that when I launch TBird and it grabs messages upon startup, it takes forever to supposedly pull them down. Once it's got them they sort relatively quickly into the proper IMAP (dovecot) folders. I don't use sieve yet; I sort with TBird rules. I don't sync messages for offline use. The only thing TB stores locally is the index cache, which I deleted and had TB rebuild once, which didn't help. All that did was waste more time, as I've got 40,000 messages in my IMAP folders which had to be re-indexed by TB. (I save all list mail for future searching). As an example of this problem, I'd not checked my email for just over day, had ~300 messages waiting in /var/mail/stan. TBird starts pulling them from dovecot and says in the status bar "downloading x of ~300". As I watch the count tick up +10 at a whack, the TB process is pegged at 100%, there is zero network activity, and the imap process on the server shows zero cpu use. It took over 60 seconds to "pull" the messages, after which TB sorted them. During the apparent sorting process, there is quite a bit of network activity and the imap process on the server is relatively busy. I say "pull" in quotes because the entire time TB is saying it's pulling more messages there is no network activity. The client and server are plugged into the same 100BaseT FDX switch (FDX verified), and the server has zero load. I know TBird isn't the greatest IMAP client around, but I think taking over 60 seconds just to download ~300 messages is way too damn long given the hardware resources, network, and load on the client and server machines. TB basically seems to be pulling, or dovecot serving, only about 5 messages/sec over 100Mb ethernet, which is abysmal performance given neither the server nor client have any load. The messages are mostly list mail which are at max a few kilobytes each. I'm leaning toward a problem with TBird but I've been unable to find a bug report that covers this, nor a forum post anywhere, etc. The closest I've found for "slow startup" are recommendations to compact folders. I have no local folders to compact. I delete immediately and expunge on exit. Anyone have any ideas? Other than switching to LDA+sieve and have TB check the IMAP folders for new mail? -- Stan

[Dovecot] Patch for logging variables
by James Devine 20 May '10

20 May '10

Upon thinking, the variable names may not be descriptive enough as `host` is a bit ambiguous and `deleted_count` may refer to a different command than expunge in imap and may be valid to track at some point so I have changed `host` to `client_ip` and `deleted_count` in imap to `expunged_count`, below is the modified diff for version 1.2.11. diff -crB dovecot-1.2.11.orig/src/imap/client.c dovecot-1.2.11/src/imap/client.c *** dovecot-1.2.11.orig/src/imap/client.c 2010-01-24 16:14:17.000000000 -0700 --- dovecot-1.2.11/src/imap/client.c 2010-05-20 09:30:47.170407921 -0600 *************** *** 42,47 **** --- 42,48 ---- client->fd_out = fd_out; client->input = i_stream_create_fd(fd_in, imap_max_line_length, FALSE); client->output = o_stream_create_fd(fd_out, (size_t)-1, FALSE); + client->expunged = 0; o_stream_set_flush_callback(client->output, client_output, client); *************** *** 105,110 **** --- 106,113 ---- static struct var_expand_table static_tab[] = { { 'i', NULL, "input" }, { 'o', NULL, "output" }, + { 'c', NULL, "client_ip" }, + { 'e', NULL, "expunged_count" }, { '\0', NULL, NULL } }; struct var_expand_table *tab; *************** *** 115,120 **** --- 118,125 ---- tab[0].value = dec2str(client->input->v_offset); tab[1].value = dec2str(client->output->offset); + tab[2].value = getenv("IP") ? getenv("IP") : "Unknown"; + tab[3].value = dec2str(client->expunged); str = t_str_new(128); var_expand(str, logout_format, tab); diff -crB dovecot-1.2.11.orig/src/imap/client.h dovecot-1.2.11/src/imap/client.h *** dovecot-1.2.11.orig/src/imap/client.h 2009-06-26 22:49:34.000000000 -0600 --- dovecot-1.2.11/src/imap/client.h 2010-05-19 16:26:31.529833893 -0600 *************** *** 133,138 **** --- 133,139 ---- unsigned int destroyed:1; unsigned int handling_input:1; unsigned int syncing:1; + unsigned int expunged; unsigned int id_logged:1; unsigned int mailbox_examined:1; unsigned int input_skip_line:1; /* skip all the data until we've diff -crB dovecot-1.2.11.orig/src/imap/cmd-close.c dovecot-1.2.11/src/imap/cmd-close.c *** dovecot-1.2.11.orig/src/imap/cmd-close.c 2010-01-24 16:14:17.000000000 -0700 --- dovecot-1.2.11/src/imap/cmd-close.c 2010-05-19 16:26:31.529833893 -0600 *************** *** 18,24 **** client->mailbox = NULL; storage = mailbox_get_storage(mailbox); ! if ((ret = imap_expunge(mailbox, NULL)) < 0) client_send_untagged_storage_error(client, storage); if (mailbox_sync(mailbox, 0, 0, NULL) < 0) client_send_untagged_storage_error(client, storage); --- 18,24 ---- client->mailbox = NULL; storage = mailbox_get_storage(mailbox); ! if ((ret = imap_expunge(client, NULL)) < 0) client_send_untagged_storage_error(client, storage); if (mailbox_sync(mailbox, 0, 0, NULL) < 0) client_send_untagged_storage_error(client, storage); diff -crB dovecot-1.2.11.orig/src/imap/cmd-expunge.c dovecot-1.2.11/src/imap/cmd-expunge.c *** dovecot-1.2.11.orig/src/imap/cmd-expunge.c 2010-01-24 16:14:17.000000000 -0700 --- dovecot-1.2.11/src/imap/cmd-expunge.c 2010-05-19 16:26:31.529833893 -0600 *************** *** 24,30 **** { struct client *client = cmd->client; ! if (imap_expunge(client->mailbox, search_args == NULL ?

[Dovecot] Dovecot LDAP problems
by Adam Pardy 20 May '10

20 May '10

I'm currently trying to configure a linux mailserver running centos to use an xserve running snow leopard. I am configuring the mailserver to run dovecot,sendmail,clamav,spam assassin and squirrelmail so it matches those used by the mac. The problem I am having is that I cannot get the server to authenticate properly to the macs LDAP database. As far as I can tell it is either a problem authenticating passwords or username and passwords. mail.app says its the password it cant authenticate Thunderbird says it could be either. It seems to be a problem in dovecot-ldap.conf, (as I can run ldapsearch from the linux server authenticate correctly and gain user information) What I'd like to know is there a standard set of settings required to authenticate to the LDAP on the mac? I'm currently running the od with no requirements for Kerberos, SSL or anything else it can authenticate with plain passwords (it will be once it is implemented I'm trying to have as few variables as possible at the moment). Copy of dovecot-ldap.conf below; 1. This file is opened as root, so it should be owned by root and mode 0600. # 1. http://wiki.dovecot.org/AuthDatabase/LDAP # 1. NOTE: If you're not using authentication binds, you'll need to give 2. dovecot-auth read access to userPassword field in the LDAP server. 3. With OpenLDAP this is done by modifying /etc/ldap/slapd.conf. There should 4. already be something like this: 1. access to attribute=userPassword 2. by dn="<dovecot's dn>" read # add this 3. by anonymous auth 4. by self write 5. by * none 1. Space separated list of LDAP hosts to use. host:port is allowed too. hosts =hostname.com 1. LDAP URIs to use. You can use this instead of hosts list. Note that this 2. setting isn't supported by all LDAP libraries. #uris = 1. Distinguished Name - the username used to login to the LDAP server dn= uid=wmuser,cn=#####,dc=##,dc=###########,dc=### 1. Password for LDAP server dnpass = password 1. Use SASL binding instead of the simple binding. Note that this changes 2. ldap_version automatically to be 3 if it's lower. Also note that SASL binds 3. and auth_bind=yes don't work together. #sasl_bind = no 1. SASL mechanism name to use. #sasl_mech = 1. SASL realm to use. #sasl_realm = 1. SASL authorization ID, ie. the dnpass is for this "master user", but the 2. dn is still the logged in user. Normally you want to keep this empty. #sasl_authz_id = 1. Use TLS to connect to the LDAP server. #tls = no 1. Use authentication binding for verifying password's validity. This works by 2. logging into LDAP server using the username and password given by client. 3. The pass_filter is used to find the DN for the user. Note that the pass_attrs 4. is still used, only the password field is ignored in it. Before doing any 5. search, the binding is switched back to the default DN. auth_bind = yes 1. If authentication binding is used, you can save one LDAP request per login 2. if users' DN can be specified with a common template. The template can use 3. the standard %variables (see user_filter). Note that you can't 4. use any pass_attrs if you use this setting. # 1. If you use this setting, it's a good idea to use a different 2. dovecot-ldap.conf for userdb (it can even be a symlink, just as long as the 3. filename is different in userdb's args). That way one connection is used only 4. for LDAP binds and another connection is used for user lookups. Otherwise 5. the binding is changed to the default DN before each user lookup. # 1. For example: auth_bind_userdn = cn=%u,cn=users,dc=##,dc=###########,dc=### # #auth_bind_userdn = 1. LDAP protocol version to use. Likely 2 or 3. ldap_version = 3 1. LDAP base. %variables can be used here. base = dc=##, dc=###########, dc=### 1. Dereference: never, searching, finding, always #deref = never 1. Search scope: base, onelevel, subtree #scope = subtree 1. User attributes are given in LDAP-name=dovecot-internal-name list. The 2. internal names are: 3. uid - System UID 4. gid - System GID 5. home - Home directory 6. mail - Mail location # 1. There are also other special fields which can be returned, see 2. http://wiki.dovecot.org/UserDatabase/ExtraFields user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid 1. Filter for user lookup. Some variables can be used (see 2. http://wiki.dovecot.org/Variables for full list): 3. %u - username 4. %n - user part in user@domain, same as %u if there's no domain 5. %d - domain part in user@domain, empty if user there's no domain user_filter = (&(objectClass=posixAccount)(uid=%u)) 1. Password checking attributes: 2. user: Virtual user name (user@domain), if you wish to change the 3. user-given username to something else 4. password: Password, may optionally start with {type}, eg. {crypt} 5. There are also other special fields which can be returned, see 6. http://wiki.dovecot.org/PasswordDatabase/ExtraFields pass_attrs = uid=user,userPassword=password 1. If you wish to avoid two LDAP lookups (passdb + userdb), you can use 2. userdb prefetch instead of userdb ldap in dovecot.conf. In that case you'll 3. also have to include user_attrs in pass_attrs field prefixed with "userdb_" 4. string. For example: #pass_attrs = uid=user,userPassword=password 1. Filter for password lookups pass_filter = (&(objectClass=posixAccount)(uid=%u)) 1. Default password scheme. "{scheme}" before password overrides this. 2. List of supported schemes is in: http://wiki.dovecot.org/Authentication default_pass_scheme = PLAIN 1. You can use same UID and GID for all user accounts if you really want to. 2. If the UID/GID is still found from LDAP reply, it overrides these values. #user_global_uid = #user_global_gid =

[Dovecot] LDAP against Novell eDirectory: 'Confidentiality required'

Hi list! I am trying to get dovecot to authenticate users against Novell eDirectory via LDAP. I have successfully gotten open-xchange to authenticate, and I have written a PHP module that authenticates, however I cannot seem to get Dovecot working. If I turn on TLS and restart dovecot, I get: dovecot: 2010-05-20 09:22:05 Error: auth(default): LDAP: ldap_start_tls_s() failed: Connect error dovecot: 2010-05-20 09:22:05 Error: auth(default): LDAP: ldap_start_tls_s() failed: Local error If I turn it off, it starts without error, but returns this when a user tries to authenticate: dovecot: 2010-05-20 08:48:39 Error: auth(default): ldap(jkmoseby,127.0.0.1): ldap_bind() failed: Confidentiality required I have tried all combinations of host:port, and LDAP uri strings I can think of, nothing seems to work.

[Dovecot] POP3 Problem with SPAM-Mail's over sieve
by Michael Niehren 20 May '10

20 May '10

Hi together, i am currently using dovecot 1.2.10 with the sieve-plugin and use a sieve-filter to sort the SPAM-Mail's directly into a Junk-Folder: require "fileinto"; # rule:[junkfilter] if header :contains "X-Spam-Flag" "YES" { fileinto "Junk"; } My problem is now, if i try to retrieve the Mails via POP3, i did not get the SPAM-Mail's in the Junk-Folder, only the normal ones, that are not filtered over the sieve plugin. Could anyone tell me how to solve that issue ? best regards Michael -- Michael Niehren __ _ powered by / / (_)__ __ ____ __ / /__/ / _ \/ // /\ \/ / /____/_/_//_/\_,_/ /_/\_\

[Dovecot] Receive Mail via lmtp/tcp
by Denny Schierz 20 May '10

20 May '10

hi, we have IMAP and SMTP (sendmail(solaris)) on different hosts. Sendmail delivers Mails via LMTP to Cyrus and Cyrus puts the mails into the (hopefully) right box. Now I want to replace the Cyrus host with Dovecot. I've searched a bit in Google but there isn't much about LMTP via TCP in combination with DoveCot. Version 2 seems to be get the feature, but we have round about 5k users, so beta is no choice. Also I red something about maidag (mailutils from Gnu) that could do the Job, but maybe there is a better way. I do not want to install Postfix (or any other SMTP service) on that IMAP Server. So I'm asking is there anybody who has the same construct. Important is, that Quota full etc. messages (RFC) gets back to sendmail, so that the MTA reject the mails, before accepting. cu denny

I don't think this really need per-user option. This is basically "system folders" and MUA will decide on their local names. Combining with autocreate plugin seems reasonable.

[Dovecot] logging
by James Devine 20 May '10

20 May '10

I am looking through the logging options and wondering if there are a couple of things that we can do 1. Logouts don't seem to show the IP address of the logout, we typically see multiple sessions at a time and wondering if there is a way to tie the logouts to an IP 2. POP logouts show the number of messages retrieved/deleted but I don't see a way to do this with IMAP, is there a logout option for this with imap? Thanks

I'm still kinda weak on Python (don't know all the cool tricks, yet), and Pike isn't found universally, so things would need to be in C for me to do it and it to be widely usable.

[Dovecot] looking for IMAP testing tool
by Phil Howard 19 May '10

19 May '10

I'm looking for an IMAP testing tool, suitable to use with Dovecot IMAP. It needs to support TLS, STARTTLS, and login/authentication. It needs to be able run from command line, shell scripts, and even do so under cron jobs (e.g. a way to supply the password to use w/o a terminal prompt). Typical interactive mail clients just don't cut it (even the text mode ones). One reason is I need to do the tests on a number of machines, under a number of user and domain names, and with a variety of parameters or destinations. This is for a suite of regression tests I am putting together intended to verify that configuration changes do not break things (or unbreak things that are supposed to not work). Anyone ever heard of such a tool? Open source would be preferred (better yet, my favorite programming languages: C, Pike, Python).

[Dovecot] problem compiling pigeonhole + my fix
by Andreas Schulze 19 May '10

19 May '10

hello, yesterday I tried to package dovecot-2.0beta5 + pigeonhole from Mercurial repository. I put pigeonhole as a subdir in the dovecot sourcetree. Following http://hg.rename-it.nl/dovecot-2.0-pigeonhole/raw-file/tip/INSTALL I called ./autogen.sh; ./configure --with-dovecot=..; make In the buildprocess I saw this output ( from autogen.sh ): Putting files in AC_CONFIG_AUX_DIR, `..'. libtoolize: `config.guess' exists: use `--force' to overwrite libtoolize: `config.sub' exists: use `--force' to overwrite libtoolize: `ltmain.sh' exists: use `--force' to overwrite I dont know *why* AC_CONFIG_AUX_DIR is .. but in .. there are the mentioned files (from dovecot) already present. The following make failed with less helpfull errors. -> my fix is to call "autoreconf -i -f" again after autogen.sh should -f be added to autogen.sh ? -- Andreas Schulze Internetdienste | P532 DATEV eG 90329 Nürnberg | Telefon +49 911 319-0 | Telefax +49 911 319-3196 E-Mail info @datev.de | Internet www.datev.de Sitz: 90429 Nürnberg, Paumgartnerstr. 6-14 | Registergericht Nürnberg, GenReg Nr.70 Vorstand Prof. Dieter Kempf (Vorsitzender) Dipl.-Kfm.

Re: [Dovecot] A new director service in v2.0 for NFS installations

We've talked about that before, that the proxy could for instance fall back to itself as the 'final server'. The people in here want to use their existing monitoring script that would do "ssh host doveadm director remove 1.2.3.4". But on top of that, yeah, maybe proxy itself could tell director that some host is down and retry the lookup. Although determining when it's down might not be fully reliable always, so I'm a bit worried that proxy could sometimes fail to connect to a mail server even if it's up (but e.g. with high load, temporary small network problem, etc).

[Dovecot] double write-locking dovecot.index.log
by Mike Abbott 19 May '10

19 May '10

Dovecot's transactions often write-lock dovecot.index.log twice (without unlocking in between), and then unlock it twice. Is that intended, or is that a bug? If I read the man pages correctly, double write-locking is pointless but safe. But double unlocking could cause data corruption during the period between the first and second unlocks, because the locks don't nest (are not refcounted). The first unlock leaves the file totally unlocked. Could this be the source of some index corruption errors? For example: 1. Process A acquires a F_WRLCK on a file. 2. Through a different code path, process A again acquires a F_WRLCK on the same file. Since these locks don't nest this is essentially a no-op. 3. Process A modifies the file. 4. Process A unlocks the file to undo the lock in step 2. Now the file has no lock on it at all. 5a. Process B locks, modifies, and unlocks the file. 5b. Process A also modifies the file, thinking that it still has a write lock. 6. Process A unlocks the file to undo the lock in step 1, but this is another no-op. Data corruption is possible if steps 5a and 5b conflict, or if 5b uses stale data. Here is a code path in dovecot-1.2.11 which exhibits the above behavior. "Outer" write lock: maildir_transaction_save_commit_pre -> maildir_transaction_save_commit_pre_sync -> maildir_sync_index_begin -> mail_index_sync_begin -> mail_index_sync_begin_to -> mail_index_sync_begin_init -> mail_transaction_log_sync_lock -> mail_transaction_log_lock_head -> mail_transaction_log_file_lock -> mail_index_lock_fd -> file_wait_lock -> file_lock_do "Inner" write lock: maildir_transaction_save_commit_pre -> maildir_sync_index_finish -> mail_index_sync_commit -> mail_index_write -> mail_transaction_log_rotate -> mail_transaction_log_file_create -> mail_transaction_log_file_create2 -> mail_transaction_log_file_lock -> mail_index_lock_fd -> file_wait_lock -> file_lock_do The file being locked is the same, dovecot.index.log. In another case, maildir_sync_index_begin is reached this way (outer lock): mailbox_sync -> mailbox_sync_init -> maildir_storage_sync_init -> maildir_sync_context -> maildir_sync_index_begin -> mail_index_sync_begin -> etc. And maildir_sync_index_finish is reached this way (inner lock): mailbox_sync -> mailbox_sync_init -> maildir_storage_sync_init -> maildir_sync_context -> maildir_sync_index_finish -> etc. Could these lead to data corruption? Please let me know if you need any more information. Thanks.

[Dovecot] how authentication works?
by Mihamina Rakotomandimby 18 May '10

18 May '10

Manao ahoana, Hello, Bonjour, I've read: http://wiki.dovecot.org/Authentication/PasswordSchemes I have a users database with clear plain passwords. Dovecot authenticates users without problems against it. Now, it's time to move to CRYPT scheme. Before that, I would like to know how things happen. He have: - the user, (entering his password in the MUA) - the user's MUA (Thunderbird, Outlook, Squirrelmail,...) - the POP or IMAP server - the users database (mySQL) with username and crypt()'d password How I think the process is: - the user enters his password in a clear way. - the MUA sends the password as the user entered it to the POP or IMAP server - the POP or IMAP server fetches the password from the database - the POP or IMAP server crypt()'s the user entered password - the POP or IMAP server compares crypt()'d ones and gives his response Am I close enough to reality? Too far? Misaotra, Thanks, Merci. -- Architecte Informatique chez Blueline/Gulfsat: Administration Systeme, Recherche & Developpement +261 3456 000 19

[Dovecot] %d is empty in mail_location
by Phil Howard 17 May '10

17 May '10

I have this in dovecot-postfix.conf: mail_location = maildir:/home/mail/dnamesum=%12MLd/dname=%Ld/unamesum=%12MLn/uname=%Ln/mail Yes, it is excessive, but that's just for testing. The pattern I really want is less clear for debugging. In postfix/main.cf I have: mailbox_command = /usr/lib/dovecot/deliver -c /etc/dovecot/dovecot-postfix.conf -a "${RECIPIENT}" I verified through strace that -a "${RECIPIENT}" is in fact getting a full user@domain address. The problem is that %d and %Ld are coming up as empty, and %12MLd is giving me the first 12 hex characters of an md5 of an empty content. It's losing the domain name somewhere. It's in the mail headers and in the -a option. So what else is needed?

[Dovecot] Setting up a 'rootless' server - user and auth_user cannot be the same

I am trying to follow http://wiki.dovecot.org/HowTo/Rootless to set up a personal dovecot server that does not use 'root' and does not need to change uids/gids. I'm trying to set it up on a Cygwin personal system. The problem I'm running into though, the directions say to set "user" and "auth_user" to be the same in this setup. However when you do this, Dovecot compains and will refuse to start up. Did I miss something? $ ./dovecot --version 1.2.11 $ ./dovecot -n # 1.2.11: /usr/local/etc/dovecot.conf Error: login_user cyg_server (uid 1005) must not be same as auth_user Fatal: Invalid configuration in /usr/local/etc/dovecot.conf Config trying to use: protocols = imap disable_plaintext_auth = no ssl = no login_chroot = no login_user = cyg_server login_process_size = 0 login_max_processes_count = 5 mail_location = maildir:~/Maildir max_mail_processes = 5 mail_process_size = 0 auth_process_size = 0 auth default { mechanisms = plain passdb passwd-file { args = /usr/local/etc/dovecot.users } userdb passwd { } user = cyg_server }

[Dovecot] Wiki page(s) to document executable tools?
by William Blunn 14 May '10

14 May '10

Motivated by a desire to know what "doveadm" does: Do we want to be having a page or pages in the Dovecot Wiki which document the executable tools? It might be an idea for each one to say: * What the tool does * How it normally gets invoked (e.g. manually by the administrator, automatically by some other part of Dovecot, automatically by something else) * What parameters it could take and what they would do List of executable tools: (found in Debian dovecot 1.0.15) lib/dovecot/ checkpassword-reply deliver dict dovecot-auth dovecot-config gdbhelper idxview imap imap-login logview managesieve managesieve-login modules pop3 pop3-login rawlog sievec sieved ssl-build-param (found in dovecot 2.0beta5) bin/ doveadm doveconf dsync libexec/dovecot/ anvil auth config dns-client dovecot-lda expire-tool imap-utf7 listview lmtp log maildirlock script ssl-params Regards, Bill

I can also see Dovecot 2.0 builds in there. But they appear to be being made every couple hours, so presumably based on the bleeding edge of the Mercurial repository. It would be kind of handy to have a Debian package of the original 2.0 beta 5 build. Is that lying around anywhere? Regards, Bill

[Dovecot] dovecot 2.0 vs. SELinux
by Michal Hlavinka 14 May '10

14 May '10

Hi, we were modifying old SELinux rules for dovecot 2.0. Everything seems ok, only one report seems odd: "SELinux is preventing /usr/sbin/dovecot "write" access on dovecot.conf." Looking at strace output, dovecot tries to use socket on /etc/dovecot/dovecot.conf which is regular file and no socket: ... geteuid() = 0 getegid() = 0 open("/dev/null", O_WRONLY) = 3 fcntl(3, F_GETFD) = 0 fcntl(3, F_SETFD, FD_CLOEXEC) = 0 socket(PF_FILE, SOCK_STREAM, 0) = 4 fcntl(4, F_GETFL) = 0x2 (flags O_RDWR) fcntl(4, F_SETFL, O_RDWR|O_NONBLOCK) = 0 connect(4, {sa_family=AF_FILE, path="/var/run/dovecot/config"}, 110) = -1 ECONNREFUSED (Connection refused) close(4) = 0 socket(PF_FILE, SOCK_STREAM, 0) = 4 fcntl(4, F_GETFL) = 0x2 (flags O_RDWR) fcntl(4, F_SETFL, O_RDWR|O_NONBLOCK) = 0 connect(4, {sa_family=AF_FILE, path="/etc/dovecot/dovecot.conf"}, 110) = -1 ECONNREFUSED (Connection refused) close(4) = 0 nanosleep({0, 70000000}, NULL) = 0 socket(PF_FILE, SOCK_STREAM, 0) = 4 fcntl(4, F_GETFL) = 0x2 (flags O_RDWR) fcntl(4, F_SETFL, O_RDWR|O_NONBLOCK) = 0 connect(4, {sa_family=AF_FILE, path="/etc/dovecot/dovecot.conf"}, 110) = -1 ECONNREFUSED (Connection refused) close(4) = 0 nanosleep({0, 90000000}, NULL) = 0 socket(PF_FILE, SOCK_STREAM, 0) = 4 fcntl(4, F_GETFL) = 0x2 (flags O_RDWR) fcntl(4, F_SETFL, O_RDWR|O_NONBLOCK) = 0 connect(4, {sa_family=AF_FILE, path="/etc/dovecot/dovecot.conf"}, 110) = -1 ECONNREFUSED (Connection refused) close(4) = 0 nanosleep({0, 80000000}, NULL) = 0 ...

[Dovecot] Compressed mail archives
by Will Palmer 14 May '10

14 May '10

Hello, I have recently begun using IMAP to access my mails, and have found that the size of my maildir is quickly getting larger than I had anticipated. Googling around, I've seen a lot of messages related to compressing individual messages in a maildir. However, what I'm really looking for is a solution which will allow multiple messages to be compressed into a single compressed file, while still allowing those messages to be accessed via IMAP. The reasoning behind this is that most of my incoming mail consists of many very-similar messages (for example, it is not unheard of for me to receive 10,000 emails detailing the same error report over a weekend, with the actual "needs to be processed" parts stuck on the end of each message) I'm expecting a simple "no, there's no way to do that", but I wouldn't mind being pleasantly surprised. My question again: Is there any way to keep a bundle of older mails compressed, so that they can enjoy the high compression of being very similar to each-other, while still allowing access via imap? A solution may involve (just throwing out ideas here, which I have no idea how to implement) putting messages older than N days into an MBox file, and either somehow linking my account to that file (so that my account consists of [compressed readonly Mbox]+[live uncompressed Maildir]), or perhaps the first half of that, but accessing archived messages through a separate account. (Not the preferred way, but if it's the only way, I'll do it) But really I don't even know if it's possible to have dovecot support MBox and Maildir simultaneously, nor do I know enough about the MBox format to even know if the IMAP-style "multiple mailboxes" thing is possible in MBox. Please excuse my no-doubt confused terminology and general air of doesn't-know-what-he's-talking-about. The internals of e-mail are generally not my thing, so I'd appreciate any pointing in the right direction which anyone may have to offer. Any ideas?

[Dovecot] Can't get Thunderbird 2 to delete a folder under mdbox (Dovecot 2.0beta5)
by William Blunn 13 May '10

13 May '10

Can't get Thunderbird 2 to delete a folder under mdbox (Dovecot 2.0beta5) I have built Dovecot 2.0 and installed it under "/opt/dovecot2". I have done the minimum configurations necesary to get it to work with SSL, systems users but with a secondary password database, and set up mail location as "mdbox:~/dbox". I had to create the directory "dbox" in the user's home directory to get things working. Using Thunderbird 2, I can happily copy messages into this system and read them out again, and that all works. In the user's "~/dbox" directory, I get a "storage" directory and a file "m.1". I can also create folders, and nested folders, and put messages into those and read them out again, and that all works. If I try to delete a folder through Thunderbird 2, what happen is that the folder gets moved to be under a folder "Trash" (which Thunderbird calls "Deleted"). So if I had a folder "foo" and deleted it, I end up with a folder "Trash/foo" (which Thunderbird calls "Deleted/foo"). Fair enough: Thunderbird is doing a trash can model on folders. I then go to remove the folder foo from "Trash". Thunderbird doesn't complain, and the folder disappears from the folder list. But upon re-starting Thunderbird, we see that the folder "foo" is still there under "Trash". So it seems the folder was never properly deleted. Perhaps this is a bug in Thunderbird 2, but since this is a beta Dovecot with a new storage subsystem, I thought I would suggest that it might be an issue with Dovecot 2.0beta5. Regards, Bill

[Dovecot] Dovecot and POP3
by DJ GRP 13 May '10

13 May '10

Hi all, I run Dovecot 1.2.9, for both IMAP and POP3 access. I was wondering if there is a way to force messages be deleted from server when the user uses POP3, even if she has selected a 'Leave messages on server' option. I was able to do it in the past using Qpopper (--enable-auto-delete option). Thanks

[Dovecot] auth: Error: PLAIN(user): Request 27511.1 timeouted after 150 secs, state=3
by Mark Sapiro 13 May '10

13 May '10

Since upgrading from Dovecot 2.0.beta4 + patches http://hg.dovecot.org/dovecot-2.0/rev/96496e1d3d12 and http://hg.dovecot.org/dovecot-2.0/rev/aefa279e2c70 to Dovecot 2.0.beta 5, I have started to see the subject error from Dovecot for SASL authentications. It doesn't happen every time, but it happens more often than not. It doesn't seem to affect Postfix's acceptance of the message.

[Dovecot] Help with acl_shared_dict
by Marcio Merlone 11 May '10

11 May '10

Hi all, I am trying to set up shared folders with dovecot 1.2.10-0xk1 on a ubuntu 8.04 server and so far so good. I managed to share a folder using GOSa GUI, but I cannot list it on Thunderbird yet, because of acl_shared_dict param (I guess). I tried BDB as per the wiki: plugin { acl_shared_dict = file:/var/lib/dovecot/shared-mailboxes.db } I gave shared-mailboxes.db 0666 perms but it keeps resetting permissions to 0600, which gives me "open(/var/lib/dovecot/shared-mailboxes.db) failed: Permission denied" errors. So I went to try sql dict, but could not find where to put sql server connection details like user, host, password. dovecot -n (with sql dict): # 1.2.10: /etc/dovecot/dovecot.conf # OS: Linux 2.6.24-27-server i686 Ubuntu 8.04.4 LTS log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps managesieve ssl_cert_file: /etc/ssl/certs/dovecot.pem ssl_key_file: /etc/ssl/private/dovecot.pem disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login mail_privileged_group: mail mail_location: maildir:~/Maildir mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): quota imap_quota acl imap_acl mail_plugins(imap): quota imap_quota acl imap_acl mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: shared separator: / prefix: shared/%%u/ location: maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u list: children lda: postmaster_address: postmaster(a)a1.ind.br hostname: a1.ind.br mail_plugins: quota sieve acl auth default: mechanisms: plain login passdb: driver: pam args: session=yes blocking=yes dovecot userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/dovecot mode: 436 user: postfix group: postfix plugin: quota: maildir:storage=10485760 acl: vfile acl_anyone: allow acl_shared_dict: proxy::acl dict: acl: mysql:/etc/dovecot-dict-sql.conf (/etc/dovecot-dict-sql.conf is a copy from the wiki) Have I missed something?

[Dovecot] Best location for indexes?

11 May '10

I cant seem to find anything via a google search, so if this has been answered I apologize. I am wondering if INDEX=MEMORY is going to give the best performance versus files? I have a server with directly attached storage, 8 gigs of ram, about 500 gigs of data. I am ok with losing and having to rebuild the indexes on a reboot as the last uptime was over 200 days

[Dovecot] Reading emails, vmail user mail access problems.
by David Haggard 11 May '10

11 May '10

Hello, I have a new installation of Ubuntu 10.04 64bit and all packages are from the Ubuntu repos. dovecot version 1.2.9 My goal is to have a basic email server setup with imap and pop support so imap users can send and receive email for the company. Setup: I have a few users that will be using this mail server so I do not need anything advanced and I am ok with creating a user account with a password and managing email addresses manually. I currently have system accounts for a test user and I have setup virtual mailbox as this mail server will host 2+ domains. Postfix is installed and running, I also confirmed mail flow to this box and from this box is working to the test user created. I can log in with the test username of the system and this is the point at which I have some issues as I am having a permission problem which I think is related to dovecot. What I am not able to do is download emails via imap client, but I can send emails just fine. If I change the permissions of the virtual mailbox to the test user that is logged in to chmod 777 I can download emails, but I can't do this for each new email to that users mailbox. /var/vmail/DOMAIN/USER1/cur/ and anything listed here will be owned by vmail so no other user can read it. (can't download emails) as dovecot seems to be trying to use USER1 as a user to read the files. How can I have dovecot read emails as vmail no matter what user logs in? I have tried many config changes using vmail but its failed so I need some advise. Here is my config: I edited the DOMAIN to hide the real domain used. # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-21-server x86_64 Ubuntu 10.04 LTS ext4 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_location: maildir:/var/vmail/DOMAIN/%n/ mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 auth default: passdb: driver: pam userdb: driver: passwd userdb: driver: static args: uid=vmail gid=vmail home=/var/vmail/DOMAIN/%n/ Thank you

[Dovecot] wrong config file?
by Phil Howard 10 May '10

10 May '10

The sample provided config file (the one I started with by editing it) included the following text: # ------------------------------ WARNING ------------------------------- > > # If there's a file /etc/dovecot/dovecot-postfix.conf, which is part of > # dovecot-postfix package, it will be used instead of dovecot.conf. > > # Keep in mind that, if that file exist, none of the changes in > # /etc/dovecot/dovecot.conf will have effect on dovecot's configuration. > # In that case you should customize /etc/dovecot/dovecot-postfix.conf. > > # ------------------------------ WARNING ------------------------------- > So I expected it would use that by default. It seems to not be doing so. Does this mean I have to modify the startup scripts to add the -c option to force the use of this config file? Or should I just put all my configs in the default "/etc/dovecot/dovecot.conf" file? When doing "dovecot -n" it became apparent that my configs were not being used. But "dovecot -c /etc/dovecot/dovecot-postfix.conf -n" was doing it. Any idea why it's not behaving as those comments described?

[Dovecot] configuration user= or auth_user=
by Phil Howard 10 May '10

10 May '10

The sample config file has: # User to use for the process. This user needs access to only user and # password databases, nothing else. Only shadow and pam authentication # requires roots, so use something else if possible. Note that passwd # authentication with BSDs internally accesses shadow files, which also # requires roots. Note that this user is NOT used to access mails. # That user is specified by userdb above. user = root # Directory where to chroot the process. Most authentication backends don't # work if this is set, and there's no point chrooting if auth_user is root. # Note that valid_chroot_dirs isn't needed to use this setting. #chroot = So is the variable for the authentication process user supposed to be "user" or "auth_user"? It would make more sense to be "auth_user". Is it just "user" for legacy reasons, and the reference to "auth_user" is in error? Or can either name be used? Also, those of you who change this, do you change it to something existing like "dovecot" or "vmail" or "nobody" or do you make a whole new user for it?

[Dovecot] lmtp_generic_maps with postfix
by derwyn 10 May '10

10 May '10

Hi All, I am new to dovecot so this may be a very easy thing to do. I need to setup a postfix+dovecot server for a multilocation setup The rules are very simple mails to *(a)local.example.com send to dovecot mails to *(a)otherlocation.example.com send to smtp:[otherlocation] But the users are created on dovecot as user(a)example.com. How can I configure dovecot to accept mails for *(a)local.example.com and deliver to *(a)example.com I use lmtp_generic_maps for a similar thing in postfix+cyrus Thanks Derwyn.

[Dovecot] problems implementing dovecot LDA with Postfix
by Stan Hoeppner 09 May '10

09 May '10

Per the instructions here http://wiki.dovecot.org/LDA and here http://wiki.dovecot.org/LDA/Postfix I set postmaster_address = postmaster(a)hardwarefreak.com in /etc/dovecot/dovecot.conf and mailbox_command = /usr/lib/dovecot/deliver in /etc/postfix/main.cf When I restart dovecot I get this: [07:17:00][root@greer]/etc/dovecot$ /etc/init.d/dovecot restart Restarting IMAP/POP3 mail server: dovecotError: Error in configuration file /etc/dovecot/dovecot.conf line 754: Unknown setting: postmaster_address Fatal: Invalid configuration in /etc/dovecot/dovecot.conf failed! And after restarting Postfix and sending a test message from a gmail account I get this in the mail log: May 9 07:26:09 greer postfix/qmgr[13384]: AEE976C32C: from=<snugmonster(a)gmail.com>, size=1628, nrcpt=1 (queue active) May 9 07:26:09 greer dovecot: deliver(stan): Fatal: postmaster_address setting not given May 9 07:26:09 greer postfix/local[13392]: AEE976C32C: to=<stan(a)hardwarefreak.com>, relay=local, delay=1.4, delays=1.3/0.03/0/0.04, dsn=4.3.0, status=deferred (temporary failure) The server is Debian Lenny 5.0.4 with Postfix 2.5.5 and Dovecot 1.2.11 from Lenny backports. Any ideas? Everything I've found via Google relating to this Dovecot startup error has to do with people converting old dovecot.conf files to a new dovecot version. -- Stan

[Dovecot] CRYPT scheme and 8 character limit
by Phil Howard 09 May '10

09 May '10

I've decided that having users supply cleartext passwords for me to encrypt and encode is a bad idea, anyway. So maybe I won't need dovecotpw. The idea is that users supply an already-encrypted password. Most of the users can fetch their login password from /etc/shadow on their own computer. Wiki page http://wiki.dovecot.org/Authentication/PasswordSchemes indicates that scheme name CRYPT is the one that uses the libc crypt() function. But it also says it uses no more than 8 characters. Then there is MD5-CRYPT. But that doesn't call crypt(), I presume. No limit on password size is indicated. But this at least looks like SOME of the encrypted passwords I have. Other passwords I have have ids indicating SHA-256 and SHA-512. Here is an example from /etc/shadow that encrypted the clear password "dovecotandpostfix" (in case it is necessary to test it): $6$IwZzpjjj$p1VrkxQmgmTED8iQnQrV3sVEZpBmw2N8oD1ykOguXB5tf8aahICesX0TF6.VMThIW2QFs1buHjT3eDtnaAFhF1 The big question is, what scheme name should I use for these passwords? I can, of course, consider the id (6 in the above example, suggesting SHA-512) if there is one (so far all are like this). But the other consideration is most of the passwords are longer than 8, some longer than 12, characters. So apparently CRYPT can't be used in those cases (so I can't have the automatic identification of crypt() to detect the scheme). What scheme would I use for the various passwords? What scheme would be used for the above example for starters? What if the id is 5 or 1 (the ones documented for the crypt() call)?

I tried the http://www.dovecot.org/tools/courier-dovecot-migrate.pl script but I still have the re-downloading event. What are your stories and advices about courier-to-dovecot move? Misaotra, Thanks, Merci. -- Architecte Informatique chez Blueline/Gulfsat: Administration Systeme, Recherche & Developpement +261 34 29 155 34 / +261 33 11 207 36

[Dovecot] Questions, Issues with 2.0
by Kelsey Cummings 08 May '10

08 May '10

I'm trying to use an external program to set the location of user's maildirs to match an existing hashing schema but the docs for how to do this in 1.x do not seem to apply to 2.0 or I'm misinterpreting them. protocol imap { mail_executable = /opt/dovecot-test/sonic-imap ... This correctly executes the and attempts to sets the MAIL variable but it appears that mail_executable is run before the user is logged in so the $USER variable isn't set and the process' uid is still 0. We also need to have dovecot include an additional maildir for each user that is currently stored outside of the user's main maildir directory into the same namespace as a specific folder name. Is there a way to do this in dovecot directly or will it need to be hacked (as it is currently with courier) or could it be done with a plugin? I've also noticed that while doveconf complains about mail_executable: May 3 13:44:10 a dovecot: config: Obsolete setting in /opt/dovecot-test/etc/dovecot/conf.d/imap.conf:7: mail_executable has been replaced by service { executable } However, when replaced as suggested by doveconf: protocol_imap { executable = /opt/dovecot-test/sonic-imap ... It fails altogether: doveconf: Fatal: Error in configuration file /opt/dovecot-test/etc/dovecot/conf.d/imap.conf line 7: Unknown setting: executable Similarly, it also suggests 'drop_priv_before_exec = no' which doesn't appear to be valid either. -- Kelsey Cummings - kgc(a)corp.sonic.net sonic.net, inc.

[Dovecot] Dovecot version mismatch - after restart

Getting the followng error when managesieve is enabled. Any other post I've read says this problem is because the service hasn't restarted after upgrade. I've restarted dovecot & postfix many times, reboot machine too. Still get the error. Racking my brains on this!!

[Dovecot] Requiring STARTTLS only on some networks
by Thomas Hummel 07 May '10

07 May '10

Hello Timo, is there a way, either in 1.2.x or in 2.x to activate disable_plaintext_auth=yes only for some address or network ? The idea would be to enable clients from the internal networks to keep making clear text connections while forbidding it to the rest of the world. Thanks. -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] Tracing sieve execution
by Jerry 07 May '10

07 May '10

I have just recently begun learning how to use sieve. For the most part, it works fine. The problem is that I have created some rather complicated rules. Occasionally, an e-mail will get sorted incorrectly and I am not able to easily determine what rule caused it to occur. Is there any way or utility that I could use to actually see what rule or line in the sieve file caused the action? -- Jerry Dovecot.user(a)seibercom.net Disclaimer: off-list followups get on-list replies or get ignored.

[Dovecot] dovecotpw documentation
by Phil Howard 07 May '10

07 May '10

Where can I find documentation on how to use the "dovecotpw" program that I was referred to? No man page. No wiki. Very little from "dovecotpw -h". What I need to do is generate the "passwd-file" contents with an MD5 scheme (the one equivalent to /etc/shadow is preferred).

[Dovecot] ACLs and public folders
by hyperbatus＠gmx.de 07 May '10

07 May '10

Dear list, I am using dovecot 1.0.15 on Debian Lenny. I have a public folder, I use ACL / vfile (without public ACL), and I use maildir / vmail. Now I have two questions: 1) http://wiki.dovecot.org/ACL states: "Mailboxes in public namespaces don't have owners, so by default no-one can access them." The same document, when explaining the meaning of the k flag in the ACLs, states: "Mailboxes can be created (or renamed) under this mailbox (there is no recursion, so creating a mailbox under this mailbox's child uses only the child's ACLs)" I have placed an ACL (dovecot-ACL) at the root of the public namespace (all rights to anyone). The public namespace was appearing correctly in my IMAP client. Then I have copied a large folder with hundreds of nested subfolders (nesting level > 3) from another account to the root of the public namespace. According to the documentation mentioned above, this should not have been possible (if I got the docs right): The first nesting level of folder should have been created, but not the messages in them and for sure not the deeper nested folders. There is no dovecot-acl within a single of the first level folders (I have verified this), so no one should have access to them. Nevertheless, in addition to the succesful copy, I can see every folder and every message in my IMAP client, I can delete and so on. Could some please explain if I got the docs wrong? 2) If there really is no ACL recursion, how are we supposed to copy large folder structures (perhaps thousands of folders, nested to 5 levels deep) to a public namespace? Do we need to create all folders by hand, then place the dovecot-acl in each folder, and then copy the messages to each folder by hand? Do we need to switch to global ACLs so that we can establish a master user for doing the act of filling the public space? Or is there a dovecot module which, immediately after creating a folder, looks into the parent folder of the new folder and copies the dovecot-acl from the parent folder to the new folder? Currently, I am very happy that dovecot didn't what it should do according to my understanding of the documentation (since I really needed to copy this folder structure to the public namespace), but on the other hand, I am a bit puzzled now not knowing if the documentation is wrong, my understanding of it is wrong or the source code is wrong :-) Thanks you very much for any help, Peter Here is the output of dovecot -n: # 1.0.15: /etc/dovecot/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot-info.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps listen: 192.168.20.23 ssl_cert_file: /etc/dovecot/imap-ssl.home.omeganet.de.crt ssl_key_file: /etc/dovecot/imap-ssl.home.omeganet.de.key ssl_parameters_regenerate: 24 ssl_cipher_list: ALL:!LOW login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_processes_count: 1 login_max_processes_count: 32 max_mail_processes: 32 mail_privileged_group: mail mail_location: maildir:~/Maildir mail_cache_fields: mail_never_cache_fields: mail_plugins: acl namespace: type: private inbox: yes namespace: type: public prefix: Archive. location: maildir:/home/vmail/archive:INDEX=~/Maildir/archive auth default: cache_size: 1 cache_ttl: 600 worker_max_count: 4 passdb: driver: passwd-file args: /etc/dovecot/passdb userdb: driver: static args: uid=vmail gid=vmail home=/home/vmail/%u socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: root plugin: acl: vfile -- GMX DSL: Internet, Telefon und Entertainment für nur 19,99 EUR/mtl.! http://portal.gmx.net/de/go/dsl02
