Hi Timo/all I am trying to use stored procedure for password query when it try to connect i get authenticated only for the first user after that for subsequent user it gives me this error. Password query failed: Commands out of sync; you can't run this command now You might have solved this issue before, did some search just found this http://www.dovecot.org/list/dovecot/2006-October/017041.html (not resloved) Could you please guide me how to resolve this issue. thanks in advance. *dovecot-mysql.conf* connect = host=xxxx dbname=dovecot user=xxx password=xxxxx client_flags=65536 user_query = SELECT xx as uid, xx as gid, home FROM table WHERE User = '%u' password_query = call proxyMayBe('%u','%w','%r'); *Dovecot -n : *# 1.2.6: /etc/dovecot.conf # OS: Linux 2.6.18-164.el5 x86_64 CentOS release 5.4 (Final) base_dir: /var/run/dovecot/ log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot-info.log protocols: imap pop3 listen: * ssl: no login_dir: /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_process_per_connection: no login_processes_count: 30 mail_location: maildir:~/ 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/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 auth default: passdb: driver: sql args: /etc/dovecot-mysql.conf userdb: driver: sql args: /etc/dovecot-mysql.conf

[Dovecot] setting up home directories
by Cliff Hayes 17 Nov '09

17 Nov '09

Hello, I have not been using the home directory but I read in MailLocation.txt that I probably should. Does dovecot create each directory? What does it put in there? My server uses mbox format. My users all look like this: [root@sendmail log]# finger chayes Login: chayes Name: 50387.00 Directory: /home/chayes Shell: /sbin/nologin Never logged in. Mail last read Mon Nov 16 19:56 2009 (CST) No Plan. So each user does have a home directory assigned, but it is never created. Here is my current mail_location: mail_location = mbox:/var/empty:INBOX=/var/spool/mail/%u:INDEX=/var/indexes/%u Do I just add the maildir component as follows: mail_location = mbox:/var/empty:INBOX=/var/spool/mail/%u:INDEX=/var/indexes/%u:maildir:/home /u% I'm confused by the MailLocation.txt entry below which says not to mix maildir and mbox formats. ---%<----------------------------------------------------------------------- -- mail_location = mbox:~/mail:INBOX=/var/mail/%u mail_location = maildir:~/Maildir:INBOX=~/Maildir/.INBOX ---%<----------------------------------------------------------------------- -- Note that it's still not possible to mix maildir and mbox formats this way. You need to use<namespaces> [Namespaces.txt] for that. Thanks in advance, Cliff

[Dovecot] deliver is ignoring mail_access_groups
by Peter 17 Nov '09

17 Nov '09

Ubuntu 8.04LTS Dovecot 1.2.6 Postfix 2.5.1 I'm using dovecot imap/deliver in an environment where I don't want users with shell access to reach their mail folders (partly to do with IMAP ACLs requiring open group permissions and partly to do with not wanting users to mess their mail folders / sieve configs up). I specifically don't want to switch to a "single dovecot user" style installation. Current config: mail_location = maildir:/home/mail/%d/%n/Maildir mail_privileged_group = mail mail_access_groups = maildir drwxrws--- 3 nobody maildir 21 2009-11-15 10:52 /home/mail drwxrws--- 4 nobody adomain.com 30 2009-11-15 12:12 /home/mail/adomain.com/ drwxrws--- 3 auser adomain.com 20 2009-11-15 10:52 /home/mail/adomain.com/auser drwxrws--- 3 auser adomain.com 20 2009-11-15 10:52 /home/mail/adomain.com/auser/Maildir And so on... As expected IMAP and Managesieve work perfectly, but deliver fails: Nov 15 12:48:26 s15364807 dovecot: deliver(auser(a)adomain.com): sieve: stat(/home/mail/adomain.com/auser/.dovecot.sieve) failed: Permission denied (using global script path in stead) Nov 15 12:28:06 s15364807 dovecot: deliver(auser(a)adomain.com): stat(/home/mail/adomain.com/auser/Maildir) failed: Permission denied Nov 15 12:28:06 s15364807 dovecot: deliver(auser(a)adomain.com): stat(/home/mail/adomain.com/auser/Maildir/tmp) failed: Permission denied (euid=1002(auser) egid=1001(adomain.com) missing +x perm: /home/mail) Nov 15 12:28:06 s15364807 dovecot: deliver(auser(a)adomain.com): msgid=<20091115122806.79A0F80034F(a)servername.com>: save failed to INBOX: Internal error occurred. Refer to server log for more information. [2009-11-15 12:28:06] Opening the permissions on /home/mail (6771) allows deliver to succeed suggesting that mail_access_groups is being ignored by deliver. As a work-around I can set /home/mail to 6771 but this is not ideal as anyone somehow guessing the directory structure could access mail of another user in the same group regardless of IMAP acl settings. Yes, I can severely obfuscate it but it's not secure. I've spent about half a day trying to figure this out, I'm assuming at this point that either I'm missing something obvious or something else is wrong. Any ideas? Peter.

[Dovecot] read() failed with subscription file
by david＠davidwbrown.name 16 Nov '09

16 Nov '09

Hello Dovecot folks, I have Dovecot running reasonably well against my Postfix SMPTd. All mail is stored in Maildir format only. In my Thunderbird client I can see the Inbox, Trash and Sent folders in the Thunderbird pane but no other directories. I have very many Maildir format directories under my Inbox directory but I cannot see them in the Thunderbird client. I have the Dovecot info and debug log runnning with the solitary error message being displayed in the log when ever I access the Thunderbird client folders pane as stated below. Particulars follow and please advise, David. OS: CentOS 5.2 Postfix: 2.3.3 Dovecot: 1.2 Dovecot log: dovecot: IMAP(user): read() failed with subscription file /home/user/Maildir/subscriptions: Is a directory

Hi! I probably have a problem with the imap folders codepages. I use polish email clients such as MS Outlook and Windows Mail. The clients try to create folders like Wiadomości-Śmieci but Dovecot creates Wiadomo&AVs-ci-&AVs-mieci This happens on two different dovecot installations 1: Installation A # 1.2.6: /etc/dovecot.conf # OS: Linux 2.6.30.9-96.fc11.x86_64 x86_64 Fedora release 11 (Leonidas) info_log_path: /var/log/maillog protocols: imaps ssl_listen: * ssl: required ssl_cert_file: /etc/pki/certs/dovecot/dovecot.pem ssl_key_file: /etc/pki/certs/dovecot/dovecot_key.pem ssl_cipher_list: ALL:!ADH!LOW:!SSLv2:!EXP:+HIGH:+MEDIUM disable_plaintext_auth: yes verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_privileged_group: dovecot_mail mail_debug: yes mail_plugins: autocreate quota imap_quota expire lda: postmaster_address: root@localhost auth default: passdb: driver: sql args: /etc/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot-sql.conf plugin: autocreate: Trash autosubscribe: Trash quota: dict:user::proxy::quota quota_rule: *:storage=1048576 quota_warning: storage=95%% /usr/local/bin/quota-warning.sh 95 quota_warning2: storage=80%% /usr/local/bin/quota-warning.sh 80 expire: Trash 7 INBOX 365 expire_dict: proxy::expire dict: quota: mysql:/etc/dovecot-dict-quota.conf expire: mysql:/etc/dovecot-dict-expire.conf 2: Installation B # 1.1.19: /usr/local/dovecot/etc/dovecot.conf # OS: Linux 2.6.22.14-72.fc6 x86_64 Fedora Core release 6 (Zod) base_dir: /usr/local/dovecot/var/run/dovecot/ log_path: /usr/local/dovecot/var/log/dovecot_log info_log_path: /usr/local/dovecot/var/log/dovecot_log protocols: imaps ssl_cert_file: /usr/local/ssl/certs/dovecot/certificate_04102009.crt ssl_key_file: /usr/local/ssl/certs/dovecot/privateKey_04102009.key ssl_cipher_list: ALL:!ADH!LOW:!SSLv2:!EXP:+HIGH:+MEDIUM verbose_ssl: yes login_dir: /usr/local/dovecot/var/run/dovecot/login login_executable: /usr/local/dovecot/libexec/dovecot/imap-login login_user: dovecot_login mail_privileged_group: dovecot_mail mail_plugins: expire quota imap_quota trash lda: postmaster_address: root@localhost hostname: filemon mail_plugins: expire quota mail_plugin_dir: /usr/local/dovecot/lib/dovecot/lda sendmail_path: /usr/sbin/sendmail auth_socket_path: /usr/local/dovecot/var/run/dovecot/auth-master auth default: mechanisms: plain login debug: yes passdb: driver: passwd-file args: /usr/local/dovecot/etc/passwd.dovecot userdb: driver: passwd-file args: /usr/local/dovecot/etc/passwd.dovecot socket: type: listen master: path: /usr/local/dovecot/var/run/dovecot/auth-master mode: 384 user: mail plugin: quota: dict:user::proxy::quotadict quota_rule: *:storage=5G:messages=2000 quota_rule2: Trash:storage=1G:messages=1000 quota_warning: storage=95%% /usr/local/bin/quota-warning.sh 95 quota_warning2: storage=80%% /usr/local/bin/quota-warning.sh 80 trash: /usr/local/dovecot/etc/dovecot-trash.conf expire: Trash 7 Spam 7 INBOX 180 Sent 180 auth_socket_path: /usr/local/dovecot/var/run/dovecot/auth-master expire_dict: proxy::expire dict: quotadict: mysql:/usr/local/dovecot/etc/dovecot-dict-quota.conf expire: mysql:/usr/local/dovecot/etc/dovecot-dict-expire.conf Please help :-) What should I do to have the right codes for the folder names?

[Dovecot] Ownership and permissions for the index directory/filesystem
by Stewart Dean 14 Nov '09

14 Nov '09

I recently upgraded from DC 1.1.15 to 1.2.6. The /var/dcindx index root directory is: drwxrwsrwt 3962 root sys 192512 Nov 13 11:56 ./ thus 3777. It appears that the user index directories created under DC1.1 look like this (here for /var/dcindx/cep): drwx--S--- 5 cep sys 256 Nov 13 14:26 cep/ while those created under V1.2 look like: drwx------ 3 lrenart sys 256 Nov 12 14:59 lrenart/ It seems that the first time that DC goes to do indexing, I now see this error msg: Nov 12 11:45:15 mercury mail:err|error dovecot: IMAP(bpyi): open(/var/spool/mail/bpyi) failed: Permission denied (euid=2586(bpyi) egid=2000(bard2) missing +w perm: /var/spool/mail) ...but never again... Questions: 1) Are the ownership and permissions on the /var/dcindx index root directory ideal or should they be something else? 2) Ideally what should the ownership and permissions be for individual user subdirs? I create the user mail directories when creating a new account, so it would be little extra trouble to create and set the ownership and permissions. I am currently using mbox mailbox format but will be migrating to maildir over the next some months.

[Dovecot] Index file (date timestamp) issue on OS X 10.6.2 Server
by Darren Latter 14 Nov '09

14 Nov '09

Hi, I've run into a bit of a problem and exhausted my knowledge and research. I'm hoping that I've overlooked something very obvious! I moved from a single Apple OS X 10.6.2 server Dovecot environment to a NFS clustered environment, currently with two servers. Both servers are identical hardware, software. Currently both the Dovecot index and data files are on the NFS RAID array. Both servers are configured to work with NFS per the Dovecot guides. The index and data files are accessed via a target link to the NFS mount via /var/spool/imap/dovecot. Email can be sent and received via either server and there are no errors being reported (both platforms are in debug mode). In essence everything appears to be working fine. The issue is that after the index is initially built (all email timestamps are correct) however any new incoming email is timestamped: 8 July 2037 23:53 I checked the index files: drwx------ 5 XXXX mail 4096 Nov 12 20:41 .UND -rw------- 1 XXXX staff 1472 Nov 13 12:30 .nfs.2005105c.0583 -rw------- 2 XXXX mail 56668 Nov 13 15:44 .nfs.200514ff.0583 -rw------- 2 XXXX mail 1364 Nov 13 15:44 .nfs.20051500.0583 drwx------ 2 XXXX mail 12288 Nov 13 15:44 cur -rw------- 1 XXXX mail 118 Nov 13 10:04 dovecot-keywords -rw------- 1 XXXX staff 5359 Nov 13 15:44 dovecot-uidlist -rw------- 1 XXXX staff 8 Nov 12 21:12 dovecot-uidvalidity -rw------- 1 XXXX mail 0 Jul 8 2037 dovecot-uidvalidity.4afc7a3a -rw------- 1 XXXX staff 1472 Nov 13 15:44 dovecot.index -rw------- 2 XXXX mail 56668 Nov 13 15:44 dovecot.index.cache -rw------- 2 XXXX mail 1364 Nov 13 15:44 dovecot.index.log -rw------- 1 XXXX mail 3859 Nov 13 15:47 maildirsize drwx------ 2 XXXX mail 4096 Nov 13 15:44 new -rw------- 1 XXXX mail 902 Nov 1 14:07 subscriptions drwx------ 2 XXXX mail 4096 Nov 13 15:44 tmp When checking the "stand alone" old data - the files are all correctly dated.

[Dovecot] Rewriting username at login
by Gerry Demaret 13 Nov '09

13 Nov '09

I am trying to make a switch from Cyrus to Dovecot which has some "historical accidents" to it that I have to deal with and ideally would like to get rid of. One of them is that about half of the existing accounts have a different format for their login. All the newer accounts have their email address as login, the old ones use a dot instead of an at: - new: user1(a)domain.tld - old: user2.domain.tld I would like to migrate away from the all-dots notation since it leads to a lot of support questions, and for that I'd like to run in a compatibility-mode for a few months. Effectively, I want to get rid of all the old users and convert them all to the new scheme, and have the username rewritten at login, so every second to last dot gets rewritten to an at. This would ensure that we have no complaints and allow our users to migrate slowly. All users are currently stored in a MySQL database for Cyrus, but this will be changed to a Dovecot-LDAP combination. Is this possible? How could I achieve this? Kind regards, Gerry.

[Dovecot] Turning off "Fixed Duplicates" feature
by Jordan Tardif 13 Nov '09

13 Nov '09

Is there a way to disable this feature? Seems to be causing more harm then good right now. Without getting into too much details it is fixing the duplcates but it does not remove the old file, and the new file it creates is not marked as read like the old one was. I understand that this problem can be created by multiple rsyncs and files changing in between, but is there any way that I can just turn this feature off all together? I do not see anything in the wiki regrading settings to disable. -- Jordan Tardif DreamHost

[Dovecot] Deliver and file system quota
by Rainer Frey 13 Nov '09

13 Nov '09

Hi, what is the quota plugin for deliver supposed to do when using fs quota? With IMAP, and not using noenforcing, a user that is over Soft limit can't copy mails. With deliver, the mail is delivered normally. When hard limit is exceeded, there is an error "rejected: Not enough disk space", just like when I don't use the plugin in lda. Even the lda setting "quota_full_tempfail = yes" works without the plugin configured in lda section. So is there any effect of the quota plugin in lda with file system quota? Thanks Rainer

[Dovecot] sieve files wont get parsed/compiled using cmusieve
by Moritz Krinke 13 Nov '09

13 Nov '09

Hello, im trying to get sieve up and running, but apparently my sieve rules file doesnt get parsed / compiled and i cant see any errors in my logfile which would point me to the problem. im using ubuntu 9.10 (and the dovecot packages from it), dovecot version is 1.1.11. in the protocol lda section of the config file i have added: mail_plugins = cmusieve mail_plugin_dir = /usr/lib/dovecot/modules/lda and in the plugins section: sieve = /var/vmail/%d/%n/.dovecot.sieve sieve_dir = /var/vmail/%d/%n/sieve root@mail:/# l /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.* -rw-r--r-- 1 root root 247470 2009-10-15 06:38 /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.a -rw-r--r-- 1 root root 1038 2009-10-15 06:37 /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.la -rw-r--r-- 1 root root 141384 2009-10-15 06:38 /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so in /var/vmail/%d/%n/ i have a dir "sieve", containing a sieve rule file and a symlink to it: ls -la .dovecot.sieve lrwxrwxrwx 1 root root 21 2009-11-07 17:14 .dovecot.sieve -> sieve/roundcube.sieve ls -la sieve/ total 16 drwxrw-rw- 3 vmail mail 4096 2009-11-07 17:02 . drwxrw---- 20 vmail mail 4096 2009-11-07 17:20 .. -rwxrw-rw- 1 vmail mail 359 2009-11-07 17:02 roundcube.sieve as i understand the documentation there should be a ".dovecot.sievec" file after the first mail arrived. But there isnt. There also is nor err file . Since the dovecot user is in the group "mail", deliver should have rw-access to the sieve file/directory. The Upload of the sieve rule via dovecots managesieve did work as expected. Would be great if anyone had an idea what/where to check next...? ;-) Thanks, Moritz

[Dovecot] UTF-8 mailbox names in filesystem
by Timo Sirainen 13 Nov '09

13 Nov '09

Currently mailbox names are stored in IMAP's modified-UTF-7 format in filesystem. I was wondering about changing this in v2.0. The default would still be to use mUTF-7 in filesystem, but just adding :UTF8 or something to mail_location could enable UTF-8. Any thoughts? Could this be dangerous somehow? UTF-8 enables a lot of weird characters, perhaps no one really wants to see them on filesystem since there's no way to type the characters? But for small systems this probably isn't a problem.

[Dovecot] Postfix and Dovecot SASL
by Rene Bakkum 12 Nov '09

12 Nov '09

Hello all, I am struggeling to get my Dovecot SASL to work within postfix. I have used the configuration example listed on the main-site of dovecot and it basically isn't giving me any success at all. I am probably missing something easy, but after spending a few days testing and walking through everything I could think about I thought figured it was better to ask :) Hope someone can point me to the right direction. My setup is that I have installed Ubuntu 9.04 (64bit), postfix and dovecot linked to a MySQL database. The services are using maildirs which are stored locally (no NFS). Postfix is using the LDA from dovecot to deliver the mail and dovecot is used for IMAP and POP3. This is working and no problems at all so far. The problem starts when I just want to enable the SASL authentication from Dovecot. I used the 'guide' posted on http://wiki.dovecot.org/HowTo/PostfixAndDovecotSASL When I try to telnet to port 25 (smtp) than I doesn't looks like the SASL is working... 220 mail003 ESMTP Postfix (Ubuntu) ehlo localhost 250-mail003 250-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250-STARTTLS 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN Anything I missed in my configuration from either postfix/dovecot? root@mail003:/etc/postfix# dovecot --version 1.1.11 root@mail003:~# dpkg-query -l postfix +++-==============-==============-============================================ ii postfix 2.5.5-1.1 High-performance mail transport agent Here are my configurations of both: root@mail003:/etc/postfix# dovecot -n # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.28-16-server x86_64 Ubuntu 9.04 ext4 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap pop3 imaps pop3s managesieve ssl_cert_file: /etc/ssl/certs/ssl-mail.pem ssl_key_file: /etc/ssl/private/ssl-mail.key ssl_cipher_list: ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM 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 login_executable(managesieve): /usr/lib/dovecot/managesieve-login login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no login_greeting_capability(managesieve): no mail_max_userip_connections(default): 10 mail_max_userip_connections(imap): 10 mail_max_userip_connections(pop3): 3 mail_max_userip_connections(managesieve): 10 mail_privileged_group: mail mail_uid: 5000 mail_gid: 5000 mail_location: maildir:/home/vmail/%d/%n/.Maildir mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_executable(managesieve): /usr/lib/dovecot/managesieve 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 mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): imap_client_workarounds(managesieve): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh pop3_client_workarounds(managesieve): sieve_storage(default): sieve_storage(imap): sieve_storage(pop3): sieve_storage(managesieve): ~/sieve sieve(default): sieve(imap): sieve(pop3): sieve(managesieve): ~/.dovecot.sieve auth default: mechanisms: plain login passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/dovecot-auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail root@mail003:/etc/postfix# postconf | grep sasl broken_sasl_auth_clients = yes cyrus_sasl_config_path = lmtp_sasl_auth_cache_name = lmtp_sasl_auth_cache_time = 90d lmtp_sasl_auth_enable = no lmtp_sasl_auth_soft_bounce = yes lmtp_sasl_mechanism_filter = lmtp_sasl_password_maps = lmtp_sasl_path = lmtp_sasl_security_options = noplaintext, noanonymous lmtp_sasl_tls_security_options = $lmtp_sasl_security_options lmtp_sasl_tls_verified_security_options = $lmtp_sasl_tls_security_options lmtp_sasl_type = cyrus proxy_write_maps = $smtp_sasl_auth_cache_name $lmtp_sasl_auth_cache_name send_cyrus_sasl_authzid = no smtp_sasl_auth_cache_name = smtp_sasl_auth_cache_time = 90d smtp_sasl_auth_enable = no smtp_sasl_auth_soft_bounce = yes smtp_sasl_mechanism_filter = smtp_sasl_password_maps = smtp_sasl_path = smtp_sasl_security_options = noplaintext, noanonymous smtp_sasl_tls_security_options = $smtp_sasl_security_options smtp_sasl_tls_verified_security_options = $smtp_sasl_tls_security_options smtp_sasl_type = cyrus smtpd_recipient_restrictions = reject_unknown_sender_domain, reject_unknown_recipient_domain, reject_unauth_pipelining, permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination smtpd_sasl_auth_enable = yes smtpd_sasl_authenticated_header = yes smtpd_sasl_exceptions_networks = smtpd_sasl_local_domain = $myhostname smtpd_sasl_path = private/dovecot-auth smtpd_sasl_security_options = noanonymous smtpd_sasl_tls_security_options = $smtpd_sasl_security_options smtpd_sasl_type = dovecot Any ideas?

[Dovecot] multiple connections per imap/pop3 process in 2.0

When I set this in master.conf: service imap { service_count = 5 } I see this error when two imap users log in: Nov 11 16:54:16 server dovecot[5432]: imap-login: Login: user=<user1>, method=PLAIN, rip=10.100.0.84, lip=10.80.0.163, pid=5573 Nov 11 16:54:31 server dovecot[5432]: imap-login: Login: user=<user2>, method=PLAIN, rip=::1, lip=::1, secured, pid=5573 Nov 11 16:54:31 server dovecot[5432]: imap(pid 5573 user user2): Fatal: setgid(2002) failed with euid=2001(user1), gid=2001, egid=2001: Operation not permitted Then both users are logged out. Is there another setting I have to change to enable multiple connections per imap/pop3 process in dovecot-2.0, or does it just not work yet? I tried changing client_limit=5 but that had no effect. (I suggest that master.conf needs more documentation.) Thanks.

[Dovecot] selective disable_plaintext_auth
by Mariano Absatz 11 Nov '09

11 Nov '09

Hi, I've been using dovecot for some time now, always with the setting: disable_plaintext_auth = yes so that no user can accidentally expose their username/password in the open. However, I'm now trying to configure a webmail client in a nearby server which doesn't support TLS or SSL IMAP connections :-( Is there any way to allow plaintext_auth only for a small set of IP addresses (for what I see in the comment, this is automatic for local addresses, alas, the webmail client is on another host).

Hi All, Sorry if this is a dumb questions, but what methods are available for retrieving mail for a system user i.e www-data. Basically my setup is just a normal Dovecot-IMAP which is working fine for shell users, but I want to be able to read mail for system users via IMAP. Is this doable? Cheers

[Dovecot] Missing 'mailbox' variable ?
by David Goncalves 10 Nov '09

10 Nov '09

Hi, I'm using Dovecot with LDAP. My users have an home directory and a field named 'mailMessageStore'. Then the full mailbox path is 'homeDirectory/mailMessageStore' In dovecot-ldap.conf i configured as follows : user_filter = (&(objectClass=qmailUser)(cn=%u)) user_attrs = qmailUID=uid,qmailGID=gid,homeDirectory=home,mailMessageStore=mail=maildir:~/%$ Everything is working as expected but... I'm using sieve and in the 'dovecot.conf' there is no way to get a variable containing the mailbox path... As the mailMessageStore field can contain something different than the login or uid, how can i get the mailbox path in the conf ? Regards. -- David Goncalves - http://www.lestat.st

[Dovecot] Auth failure delays
by Timo Sirainen 09 Nov '09

09 Nov '09

Currently Dovecot works like this when authentication fails: - the delay is always at least auth_failure_delay seconds (default: 2s) - each failed attempt doubles the delay for that specific imap/pop3 connection (no such delays for e.g. smtp) - the delay's upper limit is 3 minutes For v2.0 I was planning on making dovecot-auth process do these checks and keeping the state in anvil process: - the delay is always at least auth_failure_delay seconds (default: 2s) - for each remote IP address the delay is doubled, regardless of how the request comes (imap, pop3, smtp, etc). - the delay's upper limit is .. hardcoded to 15 secs? i kind of hate the thought of making this configurable. - each successful authentication from the IP resets the IP's delay - the delay happens before authentication is even attempted, so even successful auth attempts will have the delay (unless of course there haven't been auth failures from that IP) If the upper limit is 15 secs, that means max. 240 auth attempts per hour per IP. The reason I was thinking 15 secs is because I have some vague memories about Thunderbird dropping connection after 15 or maybe 30 seconds of idling. If user has one successful login, it's of course possible to get around the delay doubling by just doing failed attempt -> successful attempt -> failed -> success -> etc. But probably no one is really going to try to do that, and even if they did it's still not that bad. The second successful login will still have that 2 second delay before it resets the delay. So that's still max one auth/2 seconds or max. 1800 auth attempts/hour. Any thoughts?

In fact, because multiple uids (and gids) have to create a directory there, you have to use a tmp-like directory. "1xxx" means the sticky-bit, so users may not remove an entry owned by another user. Because root is owner of /var/dvindex, you have just those two users able to remove: root and the owning user of the subdir.

IMHO, as soon as you have system users the /var/dcindex must be 1777, the few exceptions, when all users share a single group, or you can pre-create the directories are the special cases. BTW: _If_ you use system users and your account name <-> uid relationship can change, you should use an template different than /var/dcindex/%u, e.g. /var/dcindex/%i, because if a new user with an name already used in past, but with another uid logs on the server, the uid cannot access the old /var/dcindex/ahinds tree. The leftover files should not make much worries, except the subscription perhaps.

[Dovecot] v2.0 lmtp logging
by Pascal Volk 05 Nov '09

05 Nov '09

Hi, I am not yet completely happy with the logging behavior of the lmtp. It logs informative messages like 'lmtp: Info: Connection closed' or 'lmtp: Info: Disconnected for inactivity'. Hm, which server was connected to the lmtp? Who was disconnected for inactivity? I think it would be useful if the lmtp would also log new connections. For example: a) TCP connections: lmtp: Info: Connection: rip=10.1.2.3, lip=10.1.2.5, cid=1255555555.12345 b) Socket connections: lmtp: Info: Connection: via socket, cid=1255555777.10452 rip: There may be multiple SMTP servers in front the IMAP server(s) lip: The lmpt may listen to more than one address cid: The 'connection ID', consists of the current unix time and the pid of the lmtp process. (Or some other values in some other format) The cid should be used in the 'saved' messages. So the delivering MTA would see something like '250 2.0.0 OK: 1255555555.12345 Saved', instead of a message like '250 2.0.0 <jdoe(a)example.com> Saved'. The lmtp should also write the cid to the log. For example: 'lmtp(jdoe): Info: msgid=123, cid=1255555555.12345: saved mail to INBOX' (or discarded because of a matching sieve rule). With this connection ID it would be possible to trace the route which the e-mail has taken. Regards, Pascal -- The trapper recommends today: c01dcafe.0929623(a)localdomain.org

Hello Everyone, First wanted to say thanks for any help in advance. I have a clustered mail system each running on centos 5.2. I have a test box that I am running the newest version on dovecot on and I am getting some random authnication failed errors. Here is the error below: Nov 04 17:31:22 auth(default): Error: worker-server(xxx(a)xxxx.com): Aborted: Lookup timed out Nov 04 17:31:23 auth(default): Info: client out: FAIL 2 user=xxx(a)xxxx.com temp The thing is, the errors only show when the user is attempting to send a message.
