[Dovecot] dovecot with Active Directory problem
by marie ot 18 Nov '10

18 Nov '10

Hello, I am using dovecot-2.0.6 with NetBSD amd64. Active Directory is used as an authentication server. (Windows Server 2008 R2) However, the message of "Operations error" was displayed first and it did not move. It solved it by understanding that this is because the authority of the user who used it for bind was insufficient, and adding to "Account Operators" group. # Though it is not the best. The error "Error: re_encode_request new request is" occurs, and it doesn't operate still as follows. Postfix operates though connects with LDAP. The following are samples. ------------------------ # Active Directory Server settings domain = example.com server_host = ldap://xxx.xxx.xxx.xxx:389 search_base = dc=example, dc=com version = 3 timeout = 30 # Active Directory Searcher settings bind = yes bind_dn = cn=Mail Administrator, cn=Users, dc=example, dc=com bind_pw = ********* # Filter Query query_filter = (&(&(objectCategory=person)(|(mail=%s)(userPrincipalName=%s)))(!(userAccountControl:1.2.840.113556.1.4.803:=2))) result_attribute = userPrincipalName result_filter = %s/ chase_referrals = no ------------------------ The packet was done with wireshark by using this definition and a capture doing and a similar test were done to dovecot. It is a setting of dovecot. ------------------------ hosts = xxx.xxx.xxx.xxx:389 dn = cn=Mail Administrator, cn=Users, dc=example, dc=com dnpass = ********* auth_bind = no ldap_version = 3 base = dc=example, dc=com user_attrs = unixHomeDirectory=home,uidNumber=uid,gidNumber=gid user_filter = (&(&(objectCategory=person)(userPrincipalName=%u))(!(userAccountControl:1.2.840.113556.1.4.803:=2))) pass_attrs = userPrincipalName=user,unixUserPassword=password pass_filter = (&(&(objectCategory=person)(userPrincipalName=%u))(!(userAccountControl:1.2.840.113556.1.4.803:=2))) iterate_attrs = userPrincipalName=user iterate_filter = (&(objectCategory=person)(!(userAccountControl:1.2.840.113556.1.4.803:=2))) default_pass_scheme = MD5 ------------------------ # Schema of LDAP is matched to Windows Services for UNIX, # and the password is made a hush with MD5. Both dovecot and postfix the first "bindRequest" was quite the same demand and the results. Next, dovecot demanded query of "userPrincipalName" and "unixUserPassword". It seems to be ok for the result. # This fails if it doesn't add to "Account Operators" group. However, "name" and "simple" were issued by the blank (anonymously?) as for the following next demand (bindRequest). In addition, query of "userPrincipalName" and "unixUserPassword" is issued to "cn=Configuration, dc=example, dc=com" afterwards. And, "Operations Error" is returned because of this. Error description in LDAP packet: ------------------------ errorMessage: 000004DC: LdapErr: DSID-0C0906DC, comment: In order to perform this operation a successful bind must be completed on the connection., data 0, v1db0 ------------------------ Because LDAP is unprofessional, it has not understood though the source code was seen. Do you serve as a reference? Thanks powerful codes.

[Dovecot] Multiple MYSQL hosts as passdb backend
by moody_cz 18 Nov '10

18 Nov '10

Hello, I use mysql as passdb backend for my dovecot 2.0.6 installation. I have 2 mysql 5.0.77 servers with master/slave replication enabled. My goal is to ensure dovecot's ability to provide its services even when one of the mysql hosts are unavailable. Here is my passdb backend conf: passdb { driver = sql args = /etc/dovecot/mysql.conf } and mysql.conf: default_pass_scheme = PLAIN driver = mysql connect = host=10.0.0.3 host=10.0.0.4 dbname=some_database user=some_user password=some_password password_query = some_query Everything works fine as long as 10.0.0.3 is up and running. However, when I shutdown mysql server on 10.0.0.3, dovecot won't even try the other host 10.0.0.4 as it is told to do in the conf. My dovecot verbose log says: Nov 16 14:29:24 auth: Error: mysql: Query failed, retrying: MySQL server has gone away Nov 16 14:29:24 auth: Error: mysql: Connect failed to 10.0.0.3 (some_database): Can't connect to MySQL server on '10.0.0.3' (111) - waiting for 1 seconds before retry Nov 16 14:30:28 auth-worker: Error: mysql: Query timed out (no free connections for 64 secs): some_sql_query Nov 16 14:30:28 auth-worker: Error: sql(mail_user,127.0.0.1): Password query failed: Not connected to database Nov 16 14:30:28 auth: Error: auth worker: Aborted request: Lookup timed out Nov 16 14:30:28 auth: Error: mysql: Connect failed to 10.0.0.3 (some_database): Can't connect to MySQL server on '10.0.0.3' (111) - waiting for 1 seconds before retry Nov 16 14:31:33 pop3-login: Info: Disconnected (auth failed, 1 attempts): user=<mail_user>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured What am I doing wrong?

[Dovecot] Debian package init scripts
by Jan Behrend 18 Nov '10

18 Nov '10

Dearest list, I am using dovecot with heartbeat-2 and I noticed that the init scripts in the Debian packages from http://xi.rename-it.nl/debian/ do not conform to the LSB standard: http://refspecs.freestandards.org/LSB_3.1.1/LSB-Core-generic/LSB-Core-gener… E.g. the return code for "program is not running" is not 3. Is there is special reason for this?

[Dovecot] add basic systemd support to dovecot
by Christophe Fergeau 17 Nov '10

17 Nov '10

Hi all, In the last days, I've been trying to add support for systemd[1] socket activation to dovecot. The basic idea is that systemd takes care of opening the sockets needed by dovecot to communicate with external processes, and when a connection happens on one of these sockets, systemd spawns dovecot, and then dovecot uses these sockets instead of creating its own sockets. The main reason why I hacked on this was that I wanted to get on-demand startup of dovecot on my home box. WIth the patch attached to this email, I'm now able to do that. The patch includes a dovecot.socket file which should be seen as a sample file, however I'm not sure what is the best way to handle this file (systemd uses it to know which sockets dovecot needs). What I wanted to ask the list for now is if such a patch is wanted, and to get feedback on how things are done in it, and what should be improved in it. [2] and [3] might be useful reading while looking at the patch. Thanks in advance for the feedback!

[Dovecot] Ongoing performance issues with 2.0.x
by Ralf Hildebrandt 17 Nov '10

17 Nov '10

Due to the ongoing performance issues with 2.0.x I switched back to 1.2.15 yesterday evening, with no changes to the machine or my users. (I migrated from 1.2.15 to 2.0.x by converting the existing config) Today, we have MUCH LESS load, with the same number of logins/min. I cannot say what exactly causes this immense increase in load, but one observation is that the time spent in system() has now dropped (user and iowait have stayed contant) to a third of the values I was seeing with 2.0.x. This evening I'll post some graphs showing two comparable 24 hour ranges. -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | http://www.charite.de

[Dovecot] \Noselect eliciting bug?

Timo, examine these two simplified sets if you will. This, is a properly working $inbox folder: d /home/david/.maildir /home/david/.maildir/dovecot.* d /home/david/.maildir/cur d /home/david/.maildir/new d /home/david/.maildir/tmp /home/david/.maildir/subscriptions This one is not, $inbox becomes \Noselect: d /home/david/.maildir /home/david/.any-file /home/david/.maildir/dovecot.* d /home/david/.maildir/cur d /home/david/.maildir/new d /home/david/.maildir/tmp /home/david/.maildir/subscriptions i can make directories willy nilly starting with a dot, but a -file- starting with a dot breaks my mailbox. it doesn't affect any other folder, just $inbox 2.0.6

Dearest list, just now I migrated a pine user to dovecot. Nothing special so far, but then I saw this in my syslog and the user reported, that he got this error message: MAIL FOLDER "INBOX" CLOSED DUE TO ACCESS ERROR Obviously this problem is related to his local filter rules: If commented out everything works like a charm. The corresponding filter rule looks for a "From"-Line in the email header but the filter string itself is empty.

[Dovecot] local users and virtual users
by Egbert Jan van den Bussche 17 Nov '10

17 Nov '10

Hi list, I'm facing this problem: I have a e few local (system) users and a bunch of virtual users (in MySQL). To make it easy for the big group, I've set a default domain which is not the domain of the server (which is just the servername). So the big group logs in with there short name without @<domain>. BUT the few system users (in passwd) cannot login to pop or imap because they get the non-local domain attached and cannot be found in the mysql db but they cannot be found in passdb either with their long name. The same applies when system users give their longname with the local domain which IS the localname of the server. This name is not in mysql nor passdb either. Is there a way to find local users in passdb when the come in with a long name? Do I need another passwd like file (i hope not...) Recap: local Domain is :mail-dev.hobby.nl default domain added bij dovecot is kader.hcc.nl kader users are found in mysql regardless if they give @kader.hcc.nl or not (then it is added) system user are never found since longname is not in mysql nor in passdb. dovecot -n: root@mail-dev:/etc/dovecot# dovecot -n # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-25-server x86_64 Ubuntu 10.04.1 LTS log_path: /var/log/dovecot/error.log info_log_path: /var/log/dovecot/info.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap pop3 imaps pop3s managesieve listen: *, [::] 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 disable_plaintext_auth: no verbose_ssl: yes 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 mail_max_userip_connections(default): 10 mail_max_userip_connections(imap): 10 mail_max_userip_connections(pop3): 3 mail_max_userip_connections(managesieve): 10 verbose_proctitle: yes first_valid_uid: 200 mail_privileged_group: vmail mail_location: maildir:~/Maildir mail_debug: yes mmap_disable: yes dotlock_use_excl: no mail_nfs_storage: yes mail_nfs_index: yes 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_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): convert autocreate mail_plugins(imap): convert autocreate mail_plugins(pop3): convert autocreate mail_plugins(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): lda: postmaster_address: postmaster deliver_log_format: msgid=%m: %$ rejection_reason: Your message to <%t> was automatically rejected:%n%r auth_socket_path: /var/run/dovecot/auth-master auth default: mechanisms: plain login realms: kader.hcc.nl hobby.nl default_realm: kader.hcc.nl cache_size: 1024 verbose: yes debug: yes debug_passwords: yes passdb: driver: pam args: failure_show_msg=yes cache_key=%u dovecot passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd args: mail=maildir:~/Maildir 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 plugin: convert_mail: mbox:/disk/mail/convert/%n autocreate: Trash autocreate2: Sent autocreate3: Drafts autocreate4: Spam autosubscribe: Trash autosubscribe2: Sent autosubscribe3: Drafts autosubscribe4: Spam Pse help.

[Dovecot] Dovecot + vpopmail + shared folders
by qmail＠top-consulting.net 17 Nov '10

17 Nov '10

I'm using dovecot 1.2.14 with vpopmail. I've enabled shared folders and the default setup was not working. The default setup being this line: location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u Going through the Archives I saw a message from Timo that said to apply a patch and use this line instead: location = maildir:/usr/home/vpopmail/domains/%d/%%n/Maildir:INDEX=~/Maildir/shared/%%u It seems like the patch is already existing in version 1.2.14 and that line works well for shared folders for domains directly under /usr/home/vpopmail/domains. However, with vpopmail after a certain number of domains, it starts putting them in /usr/home/vpopmail/domains/A, ..domains/B, etc. Shared folders do not work for those domains since my location line is forcing it to look directly in /usr/home/vpopmail/domains/xyz.com instead of /usr/home/vpopmail/domains/A/xyz.com Any workaround this ? How come we can't use %h or ~/ directly ?

German law limits the use of profiles like these quite strictly; in general an employer has no business to log all these actions generally. This does not mean it can be helpful for diagnosing problems, but I would not recommend to do so as a general procedure. On the other hands, it is a de-facto requirement today that you can trace every communiction that has entered the company. The only place where you can do this without potentiall missing some messages is the MTA. This is why all the archival tools want to couple to the MTA... JC

[Dovecot] Mail history function?
by Oliver Berse 17 Nov '10

17 Nov '10

I'm a newbie at Dovecot. For a company groupware I need a kind of a history function for mails to see which user sent which mail to whom / got which mail from whom. So I have to get the message ID of in- and outgoing mails (and write related data to a mysql database). My first idea was to monitor the log file with a daemon and search for strings like "deliver(x(a)y.z): 2010-11-15 17:34:56 Info: msgid=<AANLkTikoRgUiEg2KgUW2gLmULD4TX-bPst4yhUbuHoEH(a)a.b>". I'm not sure if this is the right approach. Does anyone know a better solution with Dovecot? thanks, Oliver

17 Nov '10

Timo, On following my previous thread that went somewhat off-topic, I noticed - or rather failed to notice - any response from you. This leaves me to draw one of the following conclusions: 1. You didn't see it. 2. You ignored it. 3. You saw it, took offense, and disregarded it. 4. You saw it, accepted the compliment for what it was - and didn't bother to respond. On the chance any of options 1-3 apply - please allow me to state as clearly as possible: your creation, that of Dovecot in general, and single-instance mdbox storage in particular, have significantly contributed to my own ease of system administration - and I offer my sincere thanks and admiration. -- Daniel

[Dovecot] Help - custom vpopmail
by Rick Romero 16 Nov '10

16 Nov '10

Hi, First, I'm not sure if dovecot should alter this, but it seems vpopmail writes the IP into the 'remote_ip' field instead of the auth type. Dovecot still writes the auth type. I want both. So I modified my vpopmail install to write an additional field into the lastauth table. My custom vpopmail writes the remote IP into remote_ip, and the auth type into a 'type' field. I tested with qmail's POP3 daemon to verify vchkpw would fill the table correcly. But I'm not sure how to get dovecot to do it: I know this is close, but there is something not right in src/auth/userdb-vpopmail.c line 99. vset_lastauth(vpop_user, vpop_domain, &auth_request->remote_ip, t_strdup_noconst(auth_request->service)); I'm, by far, NOT a C programmer - Feel free to laugh at my code publicly :) Thanks, Rick

[Dovecot] v2.0.7 released
by Timo Sirainen 16 Nov '10

16 Nov '10

http://dovecot.org/releases/2.0/dovecot-2.0.7.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.7.tar.gz.sig * master: default_process_limit wasn't actually used anywhere, rather the default was unlimited. Now that it is enforced, you might notice that the default limit is too low and you need to increase it. Dovecot logs a warning when this happens. * mail-log plugin: Log mailbox name as virtual name rather than physical name (e.g. namespace prefix is included in the name) + doveadm dump: Added imapzlib type to uncompress IMAP's COMPRESS DEFLATE I/O traffic (e.g. from rawlog). - IMAP: Fixed LIST-STATUS when listing subscriptions with subscriptions=no namespaces. - IMAP: Fixed SELECT QRESYNC not to crash on mailbox close if a lot of changes were being sent. - quota: Don't count virtual mailboxes in quota - doveadm expunge didn't always actually do the physical expunging - Fixed some index reading optimizations introduced by v2.0.5. - LMTP proxying fixes

[Dovecot] dsync mbox->mdbox: Unexpectedly lost From-line and other issues from a big conversion.
by Axel Thimm 16 Nov '10

16 Nov '10

Hi, I'm trying to convert a 33GB mail store from mbox to compressed mdbox (largest mbox is 2.7GB). The source store is live, e.g. there are mails delivered into it and mails are being read. Actually it is my own mail. :) Although my test runs were very successful I have run into trouble with the first run on the whole store. After fighting a bit around with errors like Error: Trying to open a non-listed mailbox with guid=f59c5b31b8f3df4c70180000e7dd553b I did several reruns in case these errors would be fixed on the next iteration, but my mdbox storage wasn't growing anymore. I decided to restart after removing all old index files from the source store in case I had some corruption somewhere. Since on mbox/maildir index files are completely recreatable this would just slow down thing at the worst. Indeed many of the errors went away, and I managed to convert about 10-20%, but then I hit another array of errors that would persist even after restarting: > $ grep -v Info: dsync2.log.old* > dsync2.log.old1:dsync(user): Error: Next message unexpectedly lost from mbox file /home/user/mail/lists/mplayerhq.hu/ffmpeg-devel at 58706201 (cached) > dsync2.log.old1:dsync(user): Error: read(msg input) failed: Invalid argument > dsync2.log.old1:dsync(user): Error: Next message unexpectedly lost from mbox file /home/user/mail/lists/gnupg.org/gnupg-users at 6507197 (cached) > dsync2.log.old1:dsync(user): Error: Unexpectedly lost From-line from mbox file /home/user/mail/lists/gnupg.org/gnupg-users at 6486645 > dsync2.log.old2:dsync(user): Error: mdbox /home/user/mdbox/mailboxes/lists/mplayerhq.hu/ffmpeg-devel/dbox-Mails: map uid lost for uid 26483 > dsync2.log.old2:dsync(user): Error: msg guid lookup failed: Internal error occurred.

I'd like to spot them and correct them, so I tried let's convert to maildir first, which I can debug more easily. Unfortunatly the conversion speed to maildir is about 25 times slower than converting to mdbox (wow!), and it would take almost 5 days to convert to maildir. This is no sane timeframe for debugging, so I'd rather try different tactics with mdbox. One thing I'm going to try is to do an offline conversion of a snapshot of the store. Anyway I wanted to document the issues I saw in case it is something that is a bug in dovecot. -- http://thimm.gr/ - http://ATrpms.net/

[Dovecot] POP users complaining about multiple copies of mail
by H. Wade Minter 16 Nov '10

16 Nov '10

Hello, We just switched from UW to Dovecot for our mail server. The transition went smoothly, except we have some users complaining about their email clients re-downloading mail or getting multiple copies of emails. When we go into their accounts, we only see one copy of the email, so I'm assuming there's something odd in the communication between their client and us that's causing the mail to get downloaded repeatedly. The clients that we've heard about are Outlook and one called "Goldmine". Has anyone run across this before? Scanning the archives didn't show me anything. This is Dovecot 1.2.12-1ubuntu8 on Ubuntu 10.10.

[Dovecot] Trying to building a customized auth plugin
by Antonio Perez-Aranda 16 Nov '10

16 Nov '10

I'm on dovecot 2.0.7 and I trying to building a customized auth plugin. I take passdb-passwd-file.c and userdb-passwd-file.c to try to build with a simple gcc comand out of dovecot environment as in example: export DOVECOT=/path/to/untar/dovecot-2.0.7 gcc -fPIC -shared -g -Wall -I$DOVECOT \ -I$DOVECOT/src/lib \ -I$DOVECOT/src/lib-auth \ -I$DOVECOT/src/lib-sql \ -I$DOVECOT/src/lib-settings \ -I$DOVECOT/src/lib-ntlm \ -I$DOVECOT/src/lib-master \ -I$DOVECOT/src/auth \ passdb-passwd-file.c -o passdb-passwd-file.o With this, I get errors relate with uoff_t Is possible to build this plugin by this way? Another way is patching against one plugin on dovecot RPM, but I prefer this on a separated RPM.

[Dovecot] Single-instance storage is bad for you!
by Daniel L. Miller 16 Nov '10

16 Nov '10

This single-instance storage is going to encourage bad habits! I just found myself preparing an e-mail that needs to be sent to multiple recipients - including several within my own organization - yet it's not necessary for everyone (in-house) to get the large attachment. As I was getting ready to split the message into two parts for distribution I remembered - I can just send it to EVERYBODY in-house and it only occupies a single instance - which it would anyway just being in my "sent" folder! Blasting away... You're quite the enabler, Timo! Now any mail admin who tries to lecture users on only sending attachments to those in-house personnel who really need it, because otherwise it's wasteful of precious server storage space, is going to hear the response, "Dude - don't stress out so much - just setup Dovecot with SIS!". Thanks again! -- Daniel

[Dovecot] service_count=0 for imap and pop3
by Mark Moseley 16 Nov '10

16 Nov '10

This is copy-pasted from Timo's comment in the "Todays Performance Data for 2.0.x" thread, but I didn't want to hijack that thread. In it, Timo says: <snip> service imap { service_count = 0 } (i.e. reuse imap processes) reduced the system CPU usage to almost nothing. But if you use different UIDs for different users you can't do that. </snip> Is that safe to do in imap and/or pop3? Or at least no more insecure than using service_count=0 for imap-login and pop3-login? Since I saw that comment I've been googling around and grepping the wiki but I can only find instances of using it with "service imap-login", not "service imap" or "service pop3". The mention in Timo's comment that it reduces the CPU usage by a lot got my attention, esp for pop3. We're already using service_count=0 for pop3-login and imap-login.

[Dovecot] Local node indexes in a cluster backend with GFS2
by Aliet Santiesteban Sifontes 15 Nov '10

15 Nov '10

Hi, all this days I'm testing a dovecot setup using lvs, director and a cluster email backend with two nodes using rhel5 and gfs2. In the two nodes of the email backend I configured mail location this way: mail_location = sdbox:/var/vmail/%d/%3n/%n/sdbox:INDEX=/var/indexes/%d/%3n/%n /var/vmail is shared clustered filesystem with GFS2 shared by node1 and node2 /var/indexes is a local filesystem at the node, so each node has his own /var/indexes stuff on ext3 and raid1 for improving performance, I mean each node a different /var/indexes of its own. Now, if the director was using node2 for the email for user1 and I removed node2 now all the connections for that user are redirected to node1, that node has its local /var/indexes, when this ocurr I can not see the emails that in fact are in the mailboxes, I guess should be indexes not current with the user mails. Is supposed indexes to be rebuilt automatically when the node switches?? Or I have to configure the indexes in the shared storage so the two node update the information concurrently? I will appreciate your help... best regards

[Dovecot] Is Dovecot Director stable for production??
by Aliet Santiesteban Sifontes 14 Nov '10

14 Nov '10

Today I will try Dovecot Director for a setup using a Cluster Backend with GFS2 on rhel5, my question is if is Director stable for use in production for large sites, I know is mainly designed for NFS but I believe it will do the job also for a cluster filesystem like GFS2 and should solve the mail persistence problem with a node and locking issues. I plan to add a layer behind a load balancer to do the stuff, I will appreciate if you guys can point me to best practices in configuring the director, or how the thing works since is new for me, I have seen the example conf but I don't have clarity in some of the concepts and the wiki is empty. I use 2.0.6, thank's for a great job with dovecot. best regards, Aliet

[Dovecot] Daemon will not start, invalid argument in stat of base_dir (error within)
by Frank Collette 13 Nov '10

13 Nov '10

Running CentOS 5 and Dovecot 1.2.16 Receiving error: Error: stat(/var/run/dovecot) failed: Invalid argument Fatal: Invalid configuration in /etc/dovecot.conf I've put the default dovecot.conf in place and still get the same thing. I've tried removing the /var/run/dovecot folder and letting it re-create it with no success. It creates the /var/run/dovecot folder but that is all. I've tried setting the base_dir to /tmp/dovecot to test and get the exact same error. I'm at a loss as are many other people so am hoping someone here might be able to help!

[Dovecot] dovecot sieve enotify question
by Robert Schetterer 13 Nov '10

13 Nov '10

Hi, sorry not dovecot but heres the question is it possible to use dovecot sieve enotify not only for notify mail i.e arrived but with add the incomming mail as attachment to the notification ? i.e. i have found a example require ["enotify", "fileinto", "variables"]; if header :contains "X-Spam-Flag" "YES" { set "from_addr" "admin(a)example.com"; set "subject" "Spam"; notify :message "${from_addr}: ${subject}" "mailto:user@example.com"; } is there a way to add the orginal mail as attach to the notfication mail , and finally perhaps delete it this would like a redirect/forward with right from_addr ( which should always be the default mailboxname/emailaddress -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] squirrelmail inbox empty
by Paul Cartwright 13 Nov '10

13 Nov '10

I am running Dovecot + Postfix +Squirrelmail on Debian Lenny.Fetchmail pulls the mail, dovecot spreads it around. I had squirrelmail setup & I tested it from within my router ( internal LAN). yesterday I had to go babysit my grand daughter, and I setup port forward for IMAP port 143, and I can use squirrelmail through firefox on my laptop. All the other folders have all the mail from the time I left til now. Yesterday I was reading inbpox mail, deleted a few junks, etc, and suspended my laptop. When I came back my inbox was empty, and I've never seen any more messages in it. I know I should have LOTS of older+new messages that don't get filtered. Unfortunately ssh doesn't seem to work from this linux side, it does from the windos side ( ssh keys?), so I can't get in to look at the logs.. I already removed ( I think ) all the inbox index files... & restarted, but no joy. I am not sure if it is getting filtered from the ibox, or if I just can't see it. I am not familiar with how squirrelmail works with local IMAP folders, so I am unsure where to look or what logs to browse. I will be home later today. suggestions clues or otherwise?? -- Paul Cartwright

[Dovecot] Occasional fchown errors?
by Knute Johnson 12 Nov '10

12 Nov '10

Hi: I get the occasional error below. Is there something I don't have configured correctly? Or should I just ignore this? It is not always this file, sometimes it is the cache.lock file or the log.newlock file. I have a mail client running on my computer and my phone at the same time, could that have something to do with it? Nov 10 08:32:59 rabbitbrush dovecot: IMAP(bob): fchown(/home/bob/mail/.imap/INBOX/dovecot.index.tmp, -1, 8(mail)) failed: Operation not permitted (egid=1000(bob), group based on /var/mail/bob) From dovecot -n # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-25-generic i686 Ubuntu 10.04.1 LTS log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps ssl_cert_file: /etc/ssl/certs/ssl-cert-snakeoil.pem ssl_key_file: /etc/ssl/private/ssl-cert-snakeoil.key login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mail_location: mbox:~/mail:INBOX=/var/mail/%u mbox_write_locks: fcntl dotlock auth default: passdb: driver: pam userdb: driver: passwd Thanks very much, -- Knute Johnson
