[Dovecot] Problem with sieve and namespace

Hi guys, my default sieve script fails due to an unknown mailspace even I told him to use one. What's wrong?

[Dovecot] process_min_avail being ignored?
by Douglas Mortensen 03 Mar '11

03 Mar '11

Today I found out we are having users w/ problems because: Mar 3 09:57:33 jlgray dovecot: master: Warning: service(imap-login): process_limit reached, client connections are being dropped Mar 3 09:58:42 jlgray dovecot: master: Warning: service(imap-login): process_limit reached, client connections are being dropped Mar 3 10:02:51 jlgray dovecot: master: Warning: service(imap-login): process_limit reached, client connections are being dropped Mar 3 10:04:29 jlgray dovecot: master: Warning: service(imap-login): process_limit reached, client connections are being dropped Mar 3 10:05:41 jlgray dovecot: master: Warning: service(imap-login): process_limit reached, client connections are being dropped Mar 3 10:06:58 jlgray dovecot: master: Warning: service(imap-login): process_limit reached, client connections are being dropped So, based on the dovecot2 wiki, it would seem that the solution is to follow the recommendations at http://wiki2.dovecot.org/LoginProcess, and use them as a guide for our situation. I have done so. But unless I misunderstand their purpose, I don't think they're working. Maybe I don't have them in the correct place?? I am expecting the imap-login process count to immediately jump up to 200 (based on my config below). But instead, they just slowly gradually increase. But even an hour after changing the config & restarting dovecot, I only have 78 login processes. dovecot -n output is: # 2.0.9: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0 auth_debug = yes auth_mechanisms = plain login disable_plaintext_auth = no log_timestamp = "%Y-%m-%d %H:%M:%S " mail_debug = yes mail_location = maildir:~/ mail_privileged_group = mail passdb { driver = pam } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } user = root } ssl_cert = </etc/ssl/certs/jlgray.com.cer ssl_key = </etc/ssl/private/jlgray.com.key userdb { driver = passwd } This configuration was updated from a dovecot 1.x config, by following the instructions at: http://wiki2.dovecot.org/Upgrading/2.0 Namely: doveconf -n -c dovecot-1.conf > dovecot-2.conf Then we renamed dovecot-2.conf to dovecot.conf I'm pretty sure there were no problems with that part.

[Dovecot] TB, dovecot & trailing slash - again
by Bruno Tréguier 03 Mar '11

03 Mar '11

Hi there, I have been browsing the mailing list archives in search of a solution to my problem, related to the quite infamous "trailing slash" issue with Thunderbird, but I don't seem to have found any closely related discussion. Please forgive me if this problem has already found a solution. Here I go; We use a lot of TB clients (2.x and 3.x), and we are using Dovecot 1.2.4 on our production server (mbox format). As told in many places, including this list, I added the option "tb-extra-mailbox-sep" in my dovecot.conf file. The checkbox regarding the mix of mailbox/submailbox and mailbox/messages is unchecked in the advanced options of our TB standard config. I snooped the connection with "ngrep" when creating a folder meant for containing subfolders. Here is the trace: > 6 create "ABCDE/".. < 6 OK Create completed... > 7 subscribe "ABCDE/".. < 7 OK Subscribe completed... > 8 list "" "ABCDE/".. < * LIST (\Noselect \HasChildren) "/" "ABCDE/"..8 OK List completed... So far, so good. But when you have a look at the .subscriptions file, you can see that the ABCDE folder has no trailing slash: it has been stripped off, apparently due to an "enhancement" made in 2009: http://hg.dovecot.org/dovecot-1.2/rev/339be408f49a It may be intended, but the drawback is that TB then gets a bit confused, as it has no way, during a "LIST" operation, to distinguish between a "folder/subfolder" scheme and a "folder/message" scheme: consequently, you get an error message from TB whenever you click on the containing folder, stating that "the mailbox isn't selectable". The problem is not just cosmetic, though, as the subfolders of such folders are not synchronized when selected for offline reading. I made a test with another version of Dovecot, of the 1.1 branch, and it behaves a little bit differently: the trailing slash is kept in the .subscriptions file, and everything is ok. TB is able to make the distinction between both kinds of folders. For the moment, I simply erased the "tb-extra-mailbox-sep" from my config file, and this is what happens: > 306 create "ABCDE/".. < 306 OK Create completed... > 307 subscribe "ABCDE/".. < 307 NO Invalid mailbox name: ABCDE/.. > 308 list "" "ABCDE/".. < * LIST (\Noselect \HasChildren) "/" "ABCDE/"..308 OK List completed... In that case, the "subscribe" command fails, so the folder does not appear by itself in the .subscriptions file, but as it is not used (only "terminal" mailboxes, containing messages, which are files in the filesystem), this is not a problem. The directory is created on the disk, and you can then create subfolders without any problem... Sorry for this long message, I just wanted to explain precisely what happens. A last word: switching to maildir would be quite a hassle, as we use quite a lot of procmail-based tools. Rewriting everything using Sieve is not planned for the moment. Does anyone out there have a solution for this ? What am I doing wrong ? Is the "tb-extra-mailbox-sep" really necessary when using TB ? As far as I can tell, it rather got us into trouble here, than solved anything... Thanks for any info/pointer/else !

[Dovecot] expire plugin and sieve
by cvb＠kruemel.org 03 Mar '11

03 Mar '11

Hi. I am running dovecot 1.2.9 here, allowing users to filter their mails with the sieve plugin, and am using sieve to move mail tagged as probably spam into the spam folder. I'm now looking to get the expire plugin working as well. It does work as described in the wiki: Once I manually move messages into other folders, the mysql database is filled with entries. However, the combination of sieve and expire does not seem to be working: When sieve moves messages into a folder, no entry is created in the database. Don't these plugins work together, or did I misconfigure something? # dovecot -n # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-27-server x86_64 Ubuntu 10.04.1 LTS fuse.glusterfs log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s managesieve ssl_cert_file: /etc/dovecot/imapd.pem ssl_key_file: /etc/dovecot/imapd.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(pop3): /usr/lib/dovecot/pop3-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login login_user: postfix login_process_per_connection: no login_process_size: 128 first_valid_uid: 113 mail_privileged_group: mail mail_location: maildir:/home/vmail/%Ld/%Ln:INDEX=/var/indexes/%u mail_debug: yes mail_nfs_storage: 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): expire mail_plugins(imap): expire mail_plugins(pop3): expire 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): managesieve_logout_format(default): bytes=%i/%o managesieve_logout_format(imap): bytes=%i/%o managesieve_logout_format(pop3): bytes=%i/%o managesieve_logout_format(managesieve): bytes ( in=%i : out=%o ) namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)example.com mail_plugins: expire mail_plugins: sieve auth default: mechanisms: plain login user: nobody verbose: yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: static args: uid=5000 gid=5000 home=/home/vmail/%Ld/%Ln allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: root master: path: /var/run/dovecot/auth-master mode: 438 user: vmail group: vmail plugin: sieve: /home/vmail/%Ld/%Ln/.dovecot.sieve sieve_global_path: /home/vmail/globalsieverc sieve_dir: ~/sieve sieve_global_dir: /var/lib/dovecot/sieve/global/ expire: INBOX.Trash 7 INBOX.Mailing-Lists.* 30 INBOX.Spam 14 expire_dict: proxy::expire dict: expire: mysql:/etc/dovecot/dovecot-dict-expire.conf Thanks, Christian

Hello List, I have created a shared folder in dovecot and am trying to use ACL's to limit access to it and give users who do have access the ability to create sub-directories and copy email to them.

Without ACL support enabled all works as expected. Any help would be appreciated. Eric

[Dovecot] Does dovecot proxy support message caching?
by Edward Carraro 03 Mar '11

03 Mar '11

For example, say the connection between the user and the dovecot proxy is fast/cheap, but the connection from the proxy to the dovecot imap backend server is costly. is there a way to set up the proxy to cache messages to allow faster loading? if so, does it have different levels of caching (full message, headers only, etc)? I'm using dovecot 2.0.9 for both the proxy and the imap backend. if not, is there something that can work with dovecot to allow this? Thanks!

[Dovecot] Segfault in managesieve with "sieve_extensions = -redirect"
by Sven Hartge 03 Mar '11

03 Mar '11

Hi! I've got a segfault in managesieve while using: sieve_extensions = -vacation -reject -spamtest -virustest -enotify -redirect The problem seems to lie in "-redirect". Reason for excluding "redirect" from sieve is my users should not use sieve to forward or redirect mails but use an external method (web-script to set LDAP attribute) which checks several things like active spam-checker, existing target mailbox, etc. The version ov dovecot ist 1:2.0.9-1~3.gbp785ad1~dvz60+1 on Debian Squeeze which is from the Debian maintainers git repository recompiled on Squeeze (I know, pretty wild.) doveconf -n and backtrace follow: -----------------------8<--------------------------------------------- # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0 auth_username_format = %Ln dict { quota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } disable_plaintext_auth = no first_valid_gid = 1000 first_valid_uid = 1000 last_valid_gid = 1000 last_valid_uid = 1000 mail_access_groups = virtmail mail_gid = virtmail mail_location = mdbox:~/mdbox mail_plugins = " quota zlib" mail_uid = virtmail mdbox_rotate_interval = 23 hours mdbox_rotate_size = 25 M namespace { hidden = yes inbox = yes list = yes location = prefix = INBOX. separator = . subscriptions = yes type = private } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { quota = dict:Benutzer-Quota::proxy::quota quota_rule = *:storage=2G sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = -vacation -reject -spamtest -virustest -enotify -redirect zlib_save = gz zlib_save_level = 6 } postmaster_address = postmaster(a)th-mittelhessen.de protocols = imap pop3 sieve service dict { unix_listener dict { group = virtmail mode = 0660 } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } } service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieve_deprecated { port = 2000 } } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-ldap-userdb.conf.ext driver = ldap } protocol lmtp { mail_plugins = " quota zlib sieve" } protocol lda { mail_plugins = " quota zlib sieve" } protocol imap { mail_plugins = " quota zlib imap_quota imap_zlib" } -----------------------8<--------------------------------------------- (gdb) bt full #0 sieve_extensions_set_string (svinst=<value optimized out>, ext_string=<value optimized out>) at sieve-extensions.c:567 ext = 0x0 op = 0 '\000' name = 0x2375331 "redirect" _data_stack_cur_id = 2 ext_reg = 0x23856c8 ext_names = 0x2375368 i = <value optimized out> ext_count = <value optimized out> relative = true #1 0x00007fb2db4207c2 in sieve_extensions_init (svinst=0x2385680) at sieve-extensions.c:256 extensions = <value optimized out> ext = <value optimized out> #2 0x00007fb2db426914 in sieve_init (env=0x40d700, context=<value optimized out>, debug=false) at sieve.c:83 svinst = 0x2385680 uint_setting = 0 size_setting = 37179544 pool = 0x2385660 #3 0x00000000004085ff in managesieve_capabilities_dump () at managesieve-capabilities.c:125 svinst = <value optimized out> notify_cap = <value optimized out> #4 0x0000000000408af5 in main (argc=4, argv=0x237d370) at main.c:273 set_roots = {0x610040, 0x0} service_flags = <value optimized out> storage_service_flags = 0 postlogin_socket_path = 0x0 username = 0x0 c = <value optimized out> -----------------------8<--------------------------------------------- Grüße, Sven. -- Sig lost.

We are stress testing our preproduction system. One of the "evil" tests we made was putting our mailboxes filesystem in read-only in the middle of smtp(+lda) delivery. When we try to purge one of the affected mailboxes we get error like the followings: / doveadm(lbandera@mysite): Panic: file mdbox-purge.c: line 225 (mdbox_purge_save_msg): assertion failed: (ret == (off_t)msg_size) doveadm(lbandera@mysite): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0 [0x3b0943bab0] -> /usr/lib64/dovecot/libdovecot.so.0(default_fatal_handler+0x35) [0x3b0943bb95] -> /usr/lib64/dovecot/libdovecot.so.0 [0x3b0943b4c3] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mdbox_purge+0xe83) [0x3b0986f0c3] -> /usr/bin/doveadm [0x408d65] -> /usr/bin/doveadm [0x4093c1] -> /usr/bin/doveadm(doveadm_mail_single_user+0x9d) [0x4094ed] -> /usr/bin/doveadm [0x4096fe] -> /usr/bin/doveadm(doveadm_mail_try_run+0xb7) [0x409b37] -> /usr/bin/doveadm(main+0x2fc) [0x40dddc] -> /lib64/libc.so.6(__libc_start_main+0xf4) [0x3b0881d994] -> /usr/bin/doveadm [0x408c39]/ / doveadm(leonvela@mysite): Panic: file mdbox-purge.c: line 225 (mdbox_purge_save_msg): assertion failed: (ret == (off_t)msg_size) doveadm(leonvela@mysite): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0 [0x3b0943bab0] -> /usr/lib64/dovecot/libdovecot.so.0(default_fatal_handler+0x35) [0x3b0943bb95] -> /usr/lib64/dovecot/libdovecot.so.0 [0x3b0943b4c3] -> /usr/lib64/dovecot/libdovecot-storage.so.0(mdbox_purge+0xe83) [0x3b0986f0c3] -> /usr/bin/doveadm [0x408d65] -> /usr/bin/doveadm [0x4093c1] -> /usr/bin/doveadm(doveadm_mail_single_user+0x9d) [0x4094ed] -> /usr/bin/doveadm [0x4096fe] -> /usr/bin/doveadm(doveadm_mail_try_run+0xb7) [0x409b37] -> /usr/bin/doveadm(main+0x2fc) [0x40dddc] -> /lib64/libc.so.6(__libc_start_main+0xf4) [0x3b0881d994] -> /usr/bin/doveadm [0x408c39]/ The mailboxes are damaged, but maybe doveadm should not crash on them, should handle the error more gracefully and exit with a error status.
