[Dovecot] How to do line breaks in sieve scripts?

[Dovecot] problems with sieve and lda
by Harondel J. Sibble 13 Aug '08

13 Aug '08

Okay, after reading the wiki and list archives, I am confused. I am attemping to get the deliver LDA working on a centos 5.1 system # rpm -qa | grep dovecot dovecot-1.0.7-2.el5 dovecot-sieve-1.0.2-6.el5 # rpm -qa | grep postfix postfix-2.3.3-2 so that I can use Sieve for mail filtering to imap folders, I am using the mbox format Following the wiki here for system users http://wiki.dovecot.org/LDA/Postfix I never get any info in the logs about cmusieve, the only way I see anything show up is if I add the transport settings to postfix/master.cf or see below >From reading the list archives, as best as I can tell, the only time I need to make the changes in postfix's master.cf is if I am using a virtual environment, otherwise for local delivery, all I need is the mailbox_command setting in postfix/main.cf However with that setting, I get nothing! If I then run deliver from the command line as per a couple of mailling postings, cat /etc/hosts | /usr/libexec/dovecot/deliver -d localaccount(a)mydomain.com -f mygmailaccount(a)gmail.com I get deliver(localaccount(a)mydomail.com): Aug 10 22:07:17 Info: Loading modules from directory: /usr/lib/dovecot/lda deliver(localaccount(a)mydomail.com): Aug 10 22:07:17 Info: Module loaded: /usr/lib/dovecot/lda/lib90_cmusieve_plugin.so deliver(localaccount(a)mydomail.com): Aug 10 22:07:17 Error: Can't connect to auth server at /var/run/dovecot/auth-master: No such file or directory Config stuff (dovecot -n) # 1.0.7: /etc/dovecot.conf log_path: /var/log/dovecot/dovecot.log info_log_path: /var/log/dovecot/dovecot.log protocols: imaps pop3s listen(default): *:143 listen(imap): *:143 listen(pop3): [::] ssl_listen(default): *:943 ssl_listen(imap): *:943 ssl_listen(pop3): ssl_cert_file: /etc/pki/dovecot/certs/dovecot.cert ssl_key_file: /etc/pki/tls/private/my.domain.tld.key verbose_ssl: yes 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 mail_location: mbox:~/mail:INBOX=/var/spool/mail/%u:INDEX=~/mail/.imap/.imap/indexes/ mail_debug: 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 auth default: passdb: driver: pam userdb: driver: passwd postfix/main.cf has mailbox_commmand = /usr/libexec/dovecot/deliver A .dovecot.sieve file with the following contents for testing purposes is located at ~/mail require "fileinto"; if header :comparator "i;ascii-casemap" :contains "Subject" "**SPAM**" { fileinto "Trash"; stop; } The LDA section from the dovecot.conf file protocol lda { # Address to use when sending rejection mails. # postmaster_address = # Hostname to use in various parts of sent mails, eg. in Message-Id. # Default is the system's real hostname. #hostname = # Support for dynamically loadable plugins. mail_plugins is a space separated # list of plugins to load. mail_plugin_dir = /usr/lib/dovecot/lda mail_plugins = cmusieve # Binary to use for sending mails. #sendmail_path = /usr/lib/sendmail # UNIX socket path to master authentication server to find users. #auth_socket_path = /var/run/dovecot/auth-master #sieve_global_path = script_path = ~/.dovecot.sieve log_path = /var/log/dovecot/deliverlog info_log_path = /var/log/dovecot/deliverlog debug = yes } What am I missing here to getting this working -- Harondel J.

[Dovecot] Dovecot,nfs or memory indexing
by Sebastian Tymków 13 Aug '08

13 Aug '08

Hi, I wonder if it's normal behaviour that indexes created in memory have long creation time. Other problem is that indexes created on nfs sometimes get crushed and I need to delete indexes in case of fetching mails ( I see mails on hd but when telnet on host and make stat I don't see any). Does version 1.1.x correct this errors ? And what is better to use : nfs or memory indexing ? Can someone point me adventages and disadventages of using both solutions? Best regards, Sebastian

[Dovecot] Quota does not apply.
by Dario Ale 13 Aug '08

13 Aug '08

Hello list: I am try to run quota plugin but only works a part. The users are virtual and his homedir and mbox are in NFS server, INDEX files are in local disk. Quota only is applied to global home, if I configure a low global quota and sent an mail to my e-mail, quota works fine, mail is temporally deferred. But, if I configure a high global quota and a small quota for INBOX, sent a mail that is more big that quota for INBOX, then quota is not applied and the mail is delivered to INBOX.

[Dovecot] Server-side sieve for client-side copies
by Daniel L. Miller 13 Aug '08

13 Aug '08

I know I could test this - but I'd rather ask first. To my knowledge, we haven't come up with a good server-side implementation for savings copies of sent messages (by all means correct my ignorance in this regard). So the typical way is to enable it in clients like Thunderbird (this prompted a whole discussion of how to save these messages without sending them to the server multiple times). My understanding is that sending a message from a client (use Thunderbird for simplicity of this conversation) is performed via SMTP. Saving a copy into a sent folder is performed via IMAP (hence the multiple transfers to the server). Now that I've laid a background - let's make it Dovecot specific. I don't know how "behind-the-scenes" Dovecot performs the act of saving mail messages that it receives from IMAP, instead of SMTP. Specifically, if I'm using sieve filters via deliver - can I setup a filter that will place mail copies to specific recipients into specific subfolders? -- Daniel

[Dovecot] stopping dovecot

This may be a silly question but how to correctly stop dovecot and be sure that it's possible to start it again? kill -TERM `cat /var/run/dovecot/master.pid` doesn't work well. I have imap-login processes staying arround and occupying port which leads to Fatal: listen(0.0.0.0, 993) failed: Address already in use when trying to start again 2s after stopping. -- Arkadiusz Miśkiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/

Hi I'm using dovecot imap with ldap accounts. User management interface is phamm. Internal clients connect directly using imap client. External clients must use webmail (squirrelmail). But not everyone is supposed to use webmail. Is there any way to control who is allowed to log in from a specific IP (webmail ip)? Thanx for suggestions Jan

[Dovecot] Mail quota usage errors
by Jeff Koch 12 Aug '08

12 Aug '08

Hi: We're using dovecot with qmail and vpopmail and are having problems with major inaccuracies in the mail quota usage maintained in the maildirsize file. Although the file starts off accurate after we delete it and force a rebuild it quickly becomes inaccurate. It doesn't seem to be catching new mail added to the directories. Does anyone have any suggestions or links to pages that will help us troubleshoot/correct this problem. Best Regards, Jeff Koch

Hi anyone. Can dovecot be configured to authenticate user using only SSL Certificates only and not ask for a password. So far I've got it taking the username from the common name of the certificate but I like it to use the certificate in place of the password. Is this possible and how? -- Regards Stephen.

[Dovecot] Dovecot crashing
by Erinn Looney-Triggs 12 Aug '08

12 Aug '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Sent an e-mail off as was detailed here: http://wiki.dovecot.org/MboxProblems for crashes but I also wanted to see if any of you folks had insight into the issue. Dovecot is crashing on a certain user inbox which is in mbox format as well as one of the users other mbox files. The crash doesn't exactly match what is listed in the aforementioned wiki page, so I thought their might be some other insight into this process or how to fix it. Here is the error in the log files: Aug 8 09:26:07 localhost dovecot: IMAP(user): UIDVALIDITY changed (1216167307 -> 1218134720) in mbox file /var/mail/user Aug 8 09:26:07 localhost dovecot: Panic: IMAP(user): file index-sync.c: line 39 (index_mailbox_set_recent_uid): assertion failed: (seq_range_exists(&ibox->recent_flags, uid)) Aug 8 09:26:07 localhost dovecot: IMAP(user): Raw backtrace: imap [0x80f5257] -> imap [0x80f5aa4] -> imap(i_fatal+0) [0x80f53b3] -> imap(index_mailbox_set_recent_uid+0x62) [0x80b1af9] -> imap(index_mailbox_set_recent_seq+0x33) [0x80b1b6f] -> imap [0x808ef93] - -> imap [0x808f502] -> imap [0x808fe73] -> imap(mbox_sync+0x2b) [0x8090120] -> imap(mbox_storage_sync_init+0x8b) [0x80901ee] -> imap(mailbox_sync_init+0x1b) [0x80b61df] -> imap(mailbox_sync+0x1c) [0x80b6256] -> imap(cmd_select_full+0x13b) [0x805fad7] -> imap(cmd_select+0x19) [0x805fc63] -> imap [0x8062444] -> imap [0x8062679] -> imap [0x8062777] -> imap [0x80627b3] -> imap(client_input+0xb7) [0x8062941] -> imap(io_loop_handler_run+0x17d) [0x80ff704] -> imap(io_loop_run+0x35) [0x80fea32] -> imap(main+0xb0) [0x806dd99] -> /lib/libc.so.6(__libc_start_main+0xdc) [0xc31dec] -> imap [0x805a151] Aug 8 09:26:07 localhost dovecot: child 4740 (imap) killed with signal 6 Any ideas or thoughts?

[Dovecot] Possible bug in v1.1.1
by John Wood 12 Aug '08

12 Aug '08

Greetings, I recently upgraded our server from Dovecot 1.0.14 to 1.1.1. I am building using the FreeBSD ports system, so nothing is custom aside from the flags set there. dovecot fell down a few days after the update with: pid 1823 (imap), uid 1000: exited on signal 11 the mail log shows: Jul 4 14:36:07 hostname dovecot: IMAP(username): Corrupted index cache file /home/username/mail/.imap/INBOX/dovecot.index.cache: Broken MIME parts for mail UID 10462 Jul 4 14:36:07 hostname dovecot: child 1823 (imap) killed with signal 11 unfortunately I do not have a core. The closest thing I could find in the Changelog is: v1.1.rc13 2008-06-20 Timo Sirainen <tss(a)iki.fi> - Message parser: Fixed assert-crash if cached MIME structure was broken. but, it does not appear to be the same issue. The upgrade file mentions issues with cache/index files, but they are related to downgrades. The rest of the relative information: Dovecot version: v1.1.1 Operating system: FreeBSD 6.2 p11 CPU architecture: x86 Filesystem you used: FreeBSD UFS Message that caused the crash: attached Dovecot configuration: 1.1.1: /usr/local/etc/dovecot.conf Warning: mail_extra_groups setting was often used insecurely so it is now deprecated, use mail_access_groups or mail_privileged_group instead protocols: imap imaps pop3 pop3s listen(default): 127.0.0.1:143 listen(imap): 127.0.0.1:143 listen(pop3): 127.0.0.1:110 ssl_listen(default): *:993 ssl_listen(imap): *:993 ssl_listen(pop3): *:995 ssl_ca_file: /etc/ssl/godaddy_cert/gd_intermediate.crt ssl_cert_file: /etc/ssl/godaddy_cert/hostname.cert ssl_key_file: /etc/ssl/godaddy_cert/hostname.key ssl_parameters_regenerate: 400 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 login_greeting: Hostname ready. login_process_per_connection: no login_process_size: 128 verbose_proctitle: yes first_valid_uid: 1000 first_valid_gid: 1000 mail_extra_groups: mail mail_access_groups: mail mail_location: mbox:~/mail:INBOX=/var/mail/%u mbox_read_locks: fcntl dotlock mbox_write_locks: fcntl dotlock 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_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 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix I have not been able to repeat this so far.

[Dovecot] Auth message
by Pavel Shirov 12 Aug '08

12 Aug '08

Recently my network was scanned. Various services was scanned, and checking the logs of mail server the following string draw my attention: mail dovecot: pop3-login: Disconnected: user=<ttejmgpfip>, method=PLAIN, rip=87.228.15.180, lip=x.x.x.x This looks weird to me, because pop3-login: Disconnected looks like succesful login attempt to me. I have no such user named ttejmgpfip exits ofc. I've check what dovecot writes to log if try PLAIN login method with random login/password, and it's "Aborted login". As I'm using SQL backend for user/pass database, I'm afraid that I might have something misconfigured and a possible sql-injection or something else allowed attacker to "login" with random password. Or my worries are groundless and I can get such message in some case of unsuccessful login? Running dovecot 1.0.rc15 (CentOS 5). Here is how my sql auth done: default_pass_scheme = MD5 password_query = SELECT password FROM mailbox WHERE active = '1' AND (LEFT(username, INSTR(username, '@')-1) = '%u' OR username = '%u') user_query = SELECT maildir as home, 6000 AS uid, 6000 AS gid, domain FROM mailbox WHERE LEFT(username, INSTR(username, '@')-1) = '%u' OR username = '%u' I have such query so it is possible for a user to login either as user@domain or just as user (I have single domain).

[Dovecot] About domains in antispam plugin

Hi there, I have the problem that the antispam filter is looking in a different subdirectory (I think is the domain subfolder) than the actuallly used i.e., The following error message is constant: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Aug 12 12:07:58 mail dspam[4540]: Unable to open file for reading: /var/spool/dspam/data/local/itadmin/itadmin.sig/48a1c36c24 9461173910573.sig: No such file or directory Aug 12 12:07:58 mail dspam[4541]: Unable to open file for reading: /var/spool/dspam/data/local/itadmin/itadmin.sig/48a1c36c24 9461173910573.sig: No such file or directory ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The file in the error exists but in a different subdirectory than the one AntiSpam Plugin is looking: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ls -l /var/spool/dspam/data/local/itadmin/itadmin.sig/48a1c36c249461173910573.sig ls: cannot access /var/spool/dspam/data/local/itadmin/itadmin.sig/48a1c36c249461173910573.sig: No such file or directory ls -l /var/spool/dspam/data/mydomain.com/itadmin/itadmin.sig/48a1c36c249461173910573.sig -rw-rw---- 1 root dspam 968 Aug 12 12:07 /var/spool/dspam/data/mydomain.com/itadmin/itadmin.sig/48a1c36c249461173910573.sig ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ I looked at the /etc/dovecot/dovecot.conf for a line containing a local doman vs mydomain.com but there's nothing even in the comments. So If there's something I'm missing I'd be glad you to enlight me. Thanks a lot in advance for you help. Rgds, Eduardo

[Dovecot] NFS vs CIFS - and Dovecot
by Daniel L. Miller 12 Aug '08

12 Aug '08

I've seen a number of posts discussing NFS based storage and issues with Dovecot. When the term "NFS" is used - does this exclusively refer to the Linux NFS network file system, or is it a generic reference to any network file system? I don't recall seeing any posts referencing issues with CIFS or SMBFS - is this because no one is using it, or because it just works instead of fiddling with NFS? -- Daniel

[Dovecot] Install from source of dovecot 1.1.2
by Guy 12 Aug '08

12 Aug '08

Hi guys, I have what I'm sure is a stupid question. I'm trying to install Dovecot 1.1.2 from source and my command sequence is this: cd dovecot-1.1.2 ./configure --prefix=/usr --exec-prefix=/usr --with-mysql --with-storagesmaildir --sysconfdir=/etc/dovecot make make install cd ../dovecot-sieve-1.1.5 ./configure --with-dovecot=../dovecot-1.1.2 make make install I don't get any errors during either install I've done the odd config on dovecot to try and keep it as close to the install dirs used by the Dovecot package included with Ubuntu. Once it's done, dovecot -n still looks in /usr/local/etc and when I try and start dovecot it looks for the libexec dir in /usr/local instead of /usr. Is there something I'm missing on the configure? I've very, very little experience (rather obviously) installing directly from source so any advice would be greatly appreciated. Thanks Guy -- Don't just do something...sit there!

[Dovecot] Cyrus vs Dovecot
by Mathieu Kretchner 12 Aug '08

12 Aug '08

First of all : forgive me for my poor English Hello all, I've to compare cyrus with dovecot for my work. Because these are the only solutions that could fit our needs. Unfortunately I really don't know a lot about dovecot and I would like to have some of its assets. Here are the properties of the versus table I've done : dovecot cyrus Installation: Update: Migration from cyrus : Migration from dovecot : functionalities : Management : Local Delivery : availability : Security : Indexes management : NFS compatibility : Scalability : Configuration : interoperability : Sieve filter : Documentation : Quota capability : Performance : IMAP capability : So I know this can scared you, but If you have some asset for dovecot, It could be great and a lot more FAIR !! Thank you in advance for your advice.

[Dovecot] GlusterFS
by Jeroen Koekkoek 12 Aug '08

12 Aug '08

Hi everybody, We use a Dovecot setup with GlusterFS. Dovecot 1.1.2 and GlusterFS 1.3.9. I enabled the following options (I don't have posix-locks translators): lock_method = dotlock dotlock_use_excl = no mmap_disable = yes mail_nfs_index = yes mail_nfs_storage = yes I receive the following error message. Aug 7 09:38:51 mta2 dovecot: POP3(somebody(a)domain.tld): nfs_flush_fcntl: fcntl(/var/vmail/domain.tld/somebody/Maildir/dovecot.index, F_RDLCK) failed: Function not implemented I think that I can disable mail_nfs_index to fix these messages. Has anybody had the same problem, if so, how did you solve it? Kind regards, Jeroen Koekkoek

[Dovecot] proxy_maybe and IPv6
by Matthieu Herrb 12 Aug '08

12 Aug '08

Hi, Using dovecot 1.1.2 on a dual-stack server, with the 'proxy_maybe' attribute to forward some clients to another server, it seems that only clients connecting with the same protocol version as the one used by address in the 'host' attribute in the password db are recognized as local. If an IPv4 address is specified as 'host', a dovecot proxy is created for clients connecting using IPv6 to this server, and symmetrically if the proxy is specified as an IPv6 address, clients connecting through IPv4 will get forwarded to the v6 address. Is there a way to avoid that? -- Matthieu Herrb

[Dovecot] optionnal arguments to ntlm_auth helper
by François LEGAL 10 Aug '08

10 Aug '08

Hello, I'm setting up (at least I try) to set up network services with single sign on. I could build and configure dovecat to use samba's ntlm_auth helper to achieve ntlm authentication of imap users. The point is, I wanted to restrict which users could actually authenticate through ntlm. The ntlm_auth helper has this ability with the --require-membership-of=... command line parameter. I first tried (unsuccessfully) to add this parameter to the auth_winbind_helper_path token in dovecot.conf, and figured out by checking the source that this was not possible. I then decided to patch the source so that one can pass any argument to the ntlm_auth helper by specifying at new line in dovecot.conf with the token "auth_winbind_helper_args" (for instance, what I wanted to do is "auth_winbind_helper_args = --require-membership-of=... ") Well, here comes the patch. It is to be used with recent 1.1.2 release. Best regards François

[Dovecot] tcp-wrappers.patch
by Edgar Fuß 09 Aug '08

09 Aug '08

I'd like to see tcp-wrappers.patch getting integrated into dovecot. I ported the original 1.0 patch to 1.1, but would prefer not to have to maintain another local patch. As the name suggests, the patch adds libwrap support to dovecot. We use is to limit access from outside our network to secure (imaps/pop3s) protocols only and to exclude certain internal addresses from accessing dovecot in general. I fully understand Timo's concern of people not reading documentation and then whining that librwapping doesn't work whereas they simply forgot to put hosts.{allow,deny} into the login chroot. Would it be acceptable if either dovecot itself or the init script copies /etc/hosts.{allow,deny} into the chroot (unless it's already there)? Also, dovecot could probably complain/abort/turn off libwrap if these files are missing in the login chroot. The problem mainly occurs with the default (Linux) setting of login_dir = /var/run/dovecot/login; on NetBSD, I use /var/chroot/dovecot-login instead, which doesn't get wiped out at boot. Comments? Suggestions? Oh, yes, managesieve (which uses src/login-common) would need a slight update, too.
