[Dovecot] lmtp server
by fernando＠dfcom.com.br 03 Sep '09

03 Sep '09

I believe that dovecot lmtp server will be released with 2.0 version. I working at a project that requires an lmtp server to have scalability. How about the stability of the actual version (alpha, beta ?). Is it mature to be used at production environment ? Another question, my 'ideal' setup would be to receive a message by lmtp and delivers it to an external command (like maildrop). Would it be possible. ? Best Regards, Fernando

[Dovecot] maildrop index update
by fernando＠dfcom.com.br 03 Sep '09

03 Sep '09

Hi, I´m using a multi-storage architecture in my email environment and maildrop as deliver command at mta. But to this deliver the mx servers mount nfs partitions - we need to use maildrop because many patches we inserted. How can I insert a piece of code at maildrop allowing it to update the dovecot indexes (which lib and/or function from dovecot I need to use ?) Best Regards, Fernando

[Dovecot] Question about sieve script execution
by Mel Flynn 03 Sep '09

03 Sep '09

Hi, after reading the wiki about sieve_before/sieve_after and sieve_global_path, it's still unclear to me if: sieve_before scripts are executed if no user script exists, but a global script is defined. The reason I ask, is because I'd like to use the same script, so that I don't have to maintain two scripts to apply "company policy" or "global features". It seems implicit from this sentence, but I've been taught not to assume implicitness by various pieces of software ;) "This is not possible using the sieve_global_path setting, because that is only used when the user's private script does not exist." -- Mel

[Dovecot] Sieve segfault on sieve-before scripts
by Max Ivanov 03 Sep '09

03 Sep '09

I use dovecot 1.2.4 release with sieve 0.1.12 If I setup sieve-before script and latest script contains "keep" at the very end and no personal scripts found then segfault take place. here is part of exim log: 2009-09-01 18:43:06 1MiUZA-0005V9-IB ** ivanov_maxim(a)domain.my <admin(a)domain.my> R=localuser T=local_delivery: Child process of local_delivery transport (running command "/usr/libexec/dovecot/deliver -d $local_part") was terminated by signal 11 (Segmentation fault) Once I remove "keep" from end of latest sieve-before script, everything goes fine. Here is latest global sieve script: # cat /etc/dovecot1.2/sieve-before.d/020-SENT-STORE.sieve require ["imap4flags"]; if header :contains "X-Set-Seen" ["Yes", "YES", "1"] { setflag "\\Seen"; } #keep;

[Dovecot] POP3 and AVG
by Rick Romero 02 Sep '09

02 Sep '09

Is anyone running v 1.2.3 and have clients with AVG email scanning? I upgraded a server a few weeks ago (which ran Dovecot and the Maildir mail store), and all of a sudden clients with AVG were unable to use POP. Essentially, AVG freezes. The server upgrade was from FreeBSD 7 to OpenSolaris 2009.06, and I did upgrade the Dovecot version from 1.1.17 to 1.2.3, but kept the same config. When I point those users to a port running qmail-popup on another machine (NFS mounting the new server), they work fine. I'm sure I reverted to 1.1.17 during the initial hectic days, with no change. Of course, I'm also sure I had a few of the users test the alternate qmail-popup server, maybe they did it wrong. :( Any thoughts? Should I attach compile configs? #/usr/local/sbin/dovecot -n # 1.2.3: /usr/local/etc/dovecot.conf # OS: SunOS 5.11 i86pc base_dir: /opt/csw/dovecot/ protocols: imap imaps pop3s pop3 ssl_cert_file: /etc/ssl/mail.rapid.pem ssl_key_file: /etc/ssl/mail.rapid.key ssl_key_password: password disable_plaintext_auth: no shutdown_clients: no login_dir: /opt/csw/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: VFEmail.net ready. login_process_per_connection: no login_process_size: 256 login_processes_count: 6 login_max_processes_count: 512 login_max_connections: 384 mail_max_userip_connections: 25 verbose_proctitle: yes first_valid_uid: 89 last_valid_uid: 89 first_valid_gid: 89 last_valid_gid: 89 mail_privileged_group: mail fsync_disable: yes mail_executable(default): /usr/local/libexec/dovecot/rawlog /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/rawlog /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/rawlog /usr/local/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 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 namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)vfemail.net mail_plugin_dir: /usr/local/lib/dovecot/lda sendmail_path: /var/qmail/bin/sendmail auth_socket_path: /opt/csw/dovecot/auth-master auth default: mechanisms: plain login digest-md5 cram-md5 user: vpopmail username_translation: %@ passdb: driver: vpopmail userdb: driver: passwd userdb: driver: vpopmail socket: type: listen master: path: /opt/csw/dovecot/auth-master mode: 384 user: vpopmail plugin: quota: maildir

[Dovecot] Smartsieve patch on Dovecot wiki?
by Ronald Johnson 02 Sep '09

02 Sep '09

I am attempting to get smartsieve 1.0 RC2 working with our test install of dovecot, but can not locate the Managesieve.php fix listed on the ManageSieve page: http://wiki.dovecot.org/ManageSieve/Clients Does anyone know of another location to get this fix? I've googled around, but not found an alternate location. We're running: dovecot-1.2.3 dovecot-1.2-sieve-0.1.12 dovecot-1.2-managesieve-0.11.9 The managesieve server is working fine for other ManageSieve clients such as Roundcube's managesieve and sieverules plugins, it is only smartsieve I am having problems with. Any pointers are appreciated. Cheers, Ron --

Re: [Dovecot] Question about ACL/flags
by Eric Jon Rostetter 01 Sep '09

01 Sep '09

Quoting Timo Sirainen <tss(a)iki.fi>: > You can't have per-user seen flags with mbox currently. So create a > public namespace with a maildir location and set up dovecot-acl file in > a way that allows only some specific users access to it. So for example: To refresh, I want a shared account, but my system was Dovecot 1.1 with all mbox mailboxes. Well, this is what I've done so far: 1) Upgraded to dovecot 1.2 (just because I could, I guess) 2) Tried to setup private/public namespaces... Edited "dovecot -n" output: # 1.2.4: /etc/dovecot.conf # OS: Linux 2.6.18-128.4.1.el5.centos.plus x86_64 CentOS release 5.3 (Final) [...] mail_location: mbox:~/mail/:INBOX=/var/spool/mail/%u:INDEX=/var/dovecot/indexes/ %u [...] mail_plugins(default): zlib acl mail_plugins(imap): zlib acl mail_plugins(pop3): zlib [...] namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: public separator: / prefix: shared/ location: maildir:/var/spool/mail/public:INDEX=/var/dovecot/indexes/public/%u list: no lda: postmaster_address: postmaster(a)physics.utexas.edu hostname: mail.ph.utexas.edu log_path: info_log_path: syslog_facility: mail auth default: passdb: driver: ldap args: /etc/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot-ldap.conf plugin: acl: vfile 3) Created /var/spool/mail/public/.myfolder for the account to deliver to. Created empty dovecot-shared file for it. 4) Created a .forward file in the account to run "deliver" which does in fact deliver the account's email to the right maildir location. 5) Created /var/spool/mail/public/.myfolder/dovecot-acl which has something like: owner lrwstiekxa user=me lrwstiekxa user=you lrst So, mail is delivered to this account correctly as a maildir mailbox. But, I don't know how to read it, and/or configured something incorrectly. It appears to be there, more or less: a0 namespace * NAMESPACE (("" "/")) NIL (("shared/" "/")) a0 OK Namespace completed. a0 list "" "shared/" * LIST (\Noselect \HasNoChildren) "/" "shared/" a0 OK List completed. But I can't figure out how to access it (either manuall via telnet as above, or from a client, etc). So, how do I access it, and/or what did I do wrong? While I've been doing email servers since the 1980's, this is my first try at using IMAP namespaces and shared folders, and I'm just not getting it... :( -- Eric Rostetter The Department of Physics The University of Texas at Austin This message is provided "AS IS" without warranty of any kind, either expressed or implied.

[Dovecot] Hang on login since 1.2.4
by Tom Sommer 01 Sep '09

01 Sep '09

I upgraded a number of servers to Dovecot 1.2.4, and now suddenly I get a lot of customers saying it takes a long time for them to log in. I enabled all debug and see the following: Sep 01 10:49:18 auth(default): Info: client in: AUTH 10 DIGEST-MD5 service=pop3 lip=195.41.131.35 rip=111.111.111.111 lport=110 rport=3730 Sep 01 10:49:18 auth(default): Info: digest-md5(?,111.111.111.111): Invalid realm: example.com Sep 01 10:49:25 auth(default): Info: client in: AUTH 11 PLAIN service=pop3 lip=195.41.131.35 rip=111.111.111.111 lport=110 rport=3730 resp=<hidden> Basically there is a lag of ~7-9 seconds upon login, this seems to be consistant across the servers. Any help would be greatly appreciated. // Tom

[Dovecot] fts_squat + virtual => crash
by intrigeri 01 Sep '09

01 Sep '09

Hi, dovecot's imap process segfaults when I search a virtual mailbox using the fts_squat plugin. Is this supposed to work, or a known bug? I've seen some changes commited to fts_solr a couple of months ago that where supposed to fix search issues on virtual mailboxes, maybe fts_squat needs to be fixed to? log === rawlog ------ 3551 SELECT "INBOX.virtual.unseen" 3552 UID SEARCH TEXT "catalyst" syslog ------ 11:34 kernel: [78583.208983] imap[29376]: segfault at 0 ip 0 sp 7fff9b3e1698 error 14 in imap[400000+f4000] 11:34 dovecot: dovecot: child 29376 (imap) killed with signal 11 (core dumps disabled) backtrace ========= As I'm using Debian's 1.2.1 package, the debugging symbols are stripped.
