[Dovecot] zlib plugin doesn't read concatenated .gz mailbox
by Dmitry Nezhevenko 23 Aug '11

23 Aug '11

Hi, I've observed that dovecot doesn't displays all mails from compressed via gzip mailbox (mbox). At the same time "mutt -f mailbox.gz" displays it correctly with all messages. I'm using archivemail to archive old mails. Internally it creates new "gzip" archive with "expired" messages and then concatenates it with archive. The easiest way to reproduce it without archivemail is to create two mailboxes, gzip them independently and then concatenate to one gzip archive. mutt, gunzip and other tools understands such archives. Also I've shared such mbox: http://dion.org.ua/uploads/2011/07/dovecot_test_gzip.gz It should contains ~20 messages. dovecot will "see" only two first. PS. % sudo dovecot --version 2.0.13 -- WBR, Dmitry

[Dovecot] dovecot's documentation dearth
by Postmaster 23 Aug '11

23 Aug '11

Hello. The first thing for me to say is thanks! I've been using dovecot since test 61 and it has basically performed flawlessly for me from day number 1. Dovecot makes me look like a genius sysadmin, especially compared to my colleagues struggling with exchange. So thanks, gracias, obrigado!! I'm working on a configuration for 2.0 and I'm finding the documentation somewhat difficult. I think it would be very helpful to me to have encountered a single page that detailed all available configuration sections. I don't know how to find out what the sections are, when to use them or what specifically they control. So far I've encountered... passdb plugin service protocol userdb local_name (and I think there is another one of these for ips) The service section itself would benefit from a single page detailing all of the possible types of service sections available. The next problem I've had is discovering that several parts of dovecot have no documentation at all even though they are standalone executables run by root. config, log, and ssl_params all run as root but there is also anvil and they look to me like they could support listening on a port if inet_interfaces is defined. You can say, "Relax fella, trust me. These programs are all part of dovecot and are run only if they're needed." Then I'll say, "Yes but I'm the administrator. I need to know how the parts fit together to know if the system's broken." Then you say, "Well that makes sense, but the things you're talking about aren't really configured. They are mostly internal to dovecot, they just happen to be broken out into external programs. You may as well be asking for documentation on a specific function in a library. If that's what you want, you can read through the source code." Well I guess that would be one solution. The bottom line is that it gives me an uncomfortableness to not be able to control or explain the operation of the software I'm supposedly administering. Take the program named log (which should be named dovecot-log or something less generic), it is launched even though I've specified syslog in the configuration. Logging is not interrupted when the process is killed. So, why is it running? What is it doing? Why does it need root? How do I control it? I think these are all good questions for an administrator to ask. That's my feedback for what it's worth, but mostly, thanks again for dovecot!

[Dovecot] Default and per-User sieve script
by Patrick Westenberg 23 Aug '11

23 Aug '11

Hi guys, is there any way to configure Dovecot to process the default sieve script and, after that, a user specific script? I have a default script to sort spam into a spam folder but if a user specific script is present, the default script is ignored. sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_global_path = /usr/local/etc/dovecot/sieve/default.sieve Regards Patrick

[Dovecot] dovecot deadlock with procmail
by kunal verma 23 Aug '11

23 Aug '11

I m using dovecot 1.0.7. I m having problems in mail delivery to my mail server locally. When a user sends a mail few mails are in mail Q for longer period of time. The local delivery agent(*procmail*) is trying to deliver the mail at regular interval but it is unable to deliver. But as soon as I *restart* *dovecot* the mails in the Q are delivered immediately. I suspect it is because of locking of *mbox* file of users by dovecot. How to overcome this problem as mails are some mails are taking hours to be delivered?? please let me know the solution.

[Dovecot] Large Mailbox Slow
by Matt 23 Aug '11

23 Aug '11

Doubt if there is any answer to this but will ask anyway. Have a few pop3 accounts with thousands of messages. Its slow when checking email naturally. Are there any tweaks to speed it up? I imagine there is an exchange of the message and header list which is the slow down. Too bad the list could not be compressed with gzip or something first. I think http has an option similar to that. Just asking.

[Dovecot] Dovecot Postfix and ssl_require_client_cert
by mezzo 23 Aug '11

23 Aug '11

Hi, I have a working mail system with postfix 2.7 and dovecot 1.2.15. I use secure connections for imap and smtp. When I try to use client certificate authorisation I have some problems. As soon as I enable the dovecot feature ssl_require_client_cert I have to present a valid certificate to receive or send email. Receiving emails works fine, but I can not send emails any more. The only way I could get this to work was to disable smtpd_sasl_auth_enable so postfix did not tries to get authorisation from dovecot. This way I can not have sasl authorisation for localnet and client certificate authorisation from extern. The reson seams to be that postfix does not sent the valid-client-cert along with the other parameter that are needed to satisfy the auth-process of dovecot. I found a few threads from 2008 where this problem is discussed but without a final solution. Is there a way to enable ssl_require_client_cert in dovecot and have smtpd_sasl_auth_enable=yes in postfix? Better would be a way to tell dovecot only to use ssl_require_client_cert during the imap autorisation. I did not get it to work. I miss something?

[Dovecot] Update indexes with dovecot 1.1
by Angel L. Mateo 23 Aug '11

23 Aug '11

Hello, I have a farm of dovecot 1.1 servers (debian lenny). Mailboxes are in Maildir format. Is there any way to manually update indexes? Does it worth? I mean... Our problem is that mail is delivered via dovecot lda, but, because we have a farm of servers, we don't guarantee that mail is delivered through the same server that the user is using for his imap connection, so the imap server could have this index unupdated. So I want to force an update (or at least nearly updated) in order to have the index updated in all servers at the time the user get to work. -- Angel L.

[Dovecot] Disconnected: Too many invalid IMAP commands
by Steve Fatula 23 Aug '11

Using current Apple mail 4.5 as client to Dovecot 2.0.13 I see lots of these messages in the log file for one machine and account. Near as I can tell, the client still works (it's mine), but, the messages concern me. Is there some known issue with Apple mail, or, if not, how to capture the information needed to debug?

[Dovecot] Duplicate Email with Dovecot Sieve
by Holden Hao 22 Aug '11

22 Aug '11

I am trying to use Dovecot Sieve after upgrading Dovecot from 1.0.15 to 1.2.17. I used the same config file from the old version but I added some entries to make sieve work. In my initial tests, sieve works and is able to do the actions that I set it to do. However, I get 2 copies of incoming emails. The inbox would always preserve a copy even if the sieve filter is set to transfer emails to another folder or redirect it to another address. The logs do not seem to report any issues. I don't know what causes the problem and I would appreciate some pointers. Here are some more details of my setup: OS: Linux 2.6.24.2 Dovecot: 1.2.17 Dovecot Sieve:0.1.19 Manage Sieve:0.11.13 MTA: Qmail 1.03 dovecot -n ---------------------------------------------------------------------------- # 1.2.17: /usr/local/etc/dovecot.conf # OS: Linux 2.6.24.2 i686 Debian lenny/sid log_path: /var/log/dovecot.log log_timestamp: protocols: imap pop3 imaps pop3s managesieve ssl_cert_file: /var/dir/etc/certificates/server.crt ssl_key_file: /var/dir/etc/certificates/server.key disable_plaintext_auth: no login_dir: /usr/local/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_executable(managesieve): /usr/local/libexec/dovecot/managesieve-login login_greeting: Welcome login_process_size: 32 verbose_proctitle: yes first_valid_uid: 1000 mail_location: maildir:~/Maildir mail_debug: yes 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_executable(managesieve): /usr/local/libexec/dovecot/managesieve mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugins(managesieve): 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 mail_plugin_dir(managesieve): /usr/local/lib/dovecot/managesieve imap_client_workarounds(default): outlook-idle imap_client_workarounds(imap): outlook-idle imap_client_workarounds(pop3): imap_client_workarounds(managesieve): pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): UID%u-%v pop3_uidl_format(managesieve): %08Xu%08Xv 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. location: maildir:~/Maildir inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)xxxxxxxxxx.org mail_plugin_dir: /usr/local/lib/dovecot/lda mail_plugins: quota sieve sendmail_path: /var/qmail/bin/sendmail log_path: /var/log/dovecot-deliver-errors.log info_log_path: /var/log/dovecot-deliver.log auth default: verbose: yes passdb: driver: checkpassword args: /var/qmail/bin/auth_pop userdb: driver: prefetch plugin: quota: maildir sieve: ~/.dovecot.sieve sieve_dir: ~/sieve -------------------------------------------------------------------- from: dovecot-deliver.log -------------------------------------------------------------------- deliver(user): Info: Loading modules from directory: /usr/local/lib/dovecot/lda deliver(user): Info: Module loaded: /usr/local/lib/dovecot/lda/lib10_quota_plugin.so deliver(user): Info: Module loaded: /usr/local/lib/dovecot/lda/lib90_sieve_plugin.so deliver(user): Info: Quota root: name= backend=maildir args= deliver(user): Info: Namespace: type=private, prefix=INBOX., sep=., inbox=yes, hidden=no, list=1, subscriptions=yes deliver(user): Info: maildir: data=/home/user/Maildir deliver(user): Info: maildir++: root=/home/user/Maildir, index=, control=, inbox=/home/user/Maildir deliver(user): Info: sieve: using sieve path for user's script: /home/user/.dovecot.sieve deliver(user): Info: sieve: opening script /home/user/.dovecot.sieve deliver(user): Info: sieve: executing compiled script /home/user/.dovecot.sieve deliver(user): Info: sieve: msgid=< CAJNnNYmQpmEopFfT3+_qHvXYxf3v-4bzv9ojJqGfRtcddnTg8g(a)mail.gmail.com>: stored mail into mailbox 'Inbox.Test' Thanks in advance for your replies.

[Dovecot] Dovecot 1.2.16 and Thunderbird 5 - pop3 mails not getting deleted
by Ian Evans 22 Aug '11

22 Aug '11

I run a Dovecot 1.2.16 pop3 server and have just started using the Thunderbird 5 email client. Thunderbird is set to leave the messages on the server unless they are over 91 days old. However, I'm not seeing it delete any of the older messages. I'll run a debug run of Thunderbird when I get back home, but I'm just wondering if there's any gotcha's I should be aware of with Thunderbird and Dovecot in a pop3 environment. The Thunderbird folks are wondering if it's the server not the client. Thanks.

Upgrading to Dovecot2 would allow you to solve this in various ways: - use "doveadm force-resync" - user director to bind to a particular server You could put the indices on a shared filesystem. If neither an update nor shared indices are feasible, maybe you can enable the master user feature, and run a script that logs in as each user and do an IMAP operation that will force a resync of the INBOX indices. For example, # On IMAP server with a localhost interface for u in $users; do echo "1 login $u*master masterpw\n2 SELECT INBOX\n3 logout" | \ nc 127.0.0.1 143 done Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Sharing all mailboxes and userdb LDAP attrs
by Felipe Scarel 19 Aug '11

19 Aug '11

Hello all, I'm setting up a Dovecot environment here, version 1.2.15 on Debian 6.0.2 "squeeze". This is actually a complete revamp of the previous setup we have in-place here, built from the ground up with updated versions of all involved software. The operators have told me that they use some scripts hacked up by a previous sysadmin to give a single "admin" account full access to all user mail. That is, if any user runs into problems, they: 1. Call in; 2. The operator logs in as the admin user; 3. Operator performs maintenance duties on user email. I've been researching the possibility of using Dovecot shared namespaces to perform that very same task in a better fashion in this new server. So far, I've been able to globally share users' INBOXes and view them from a single admin account (through user= entries on global acl's). My ultimate goal, however, is to have access to all user mailboxes with any user that's a member of a particular group, adding all operators to that group as needed. - - - - - First question, then, is this one: how can I give global access to all user mailboxes? I've read that it's possible to give access to all subfolders of a particular folder throught the use of a .DEFAUL acl. That didn't seem to work with the uppermost directory, however. Here's what I tried: root@mail:/etc/dovecot# dovecot -a | grep acl: acl: vfile:/etc/dovecot/acl:cache_secs=300 root@mail:/etc/dovecot# cat acl/.DEFAULT owner lrwstipekxa user=admin lrwstipekxa Renaming .DEFAULT to INBOX does achieve the intended goal, but only for the INBOX folder evidently. - - - - - Second question is somewhat simpler. So far I've been using a single admin user, but I'd like to switch to using an admin group in the future. I've read that the best way to do that would be to use the user_attrs entry in my dovecot-ldap.conf file, while using a userdb ldap. The groups should be strings separated by commas in the appropriate attribute, from what I understand. Is there any readily-available or recommended schema I can use to fill up that attribute? I'm using the default ones (plus samba.schema) but I've seen mostly space to fit GID's, not group names. Thanks in advance, fbscarel PS: Here's my dovecot -a output, should it be needed. - - - - - root@mailaluno:~# dovecot -a # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian

[Dovecot] Dovecot-Antispam 2.0 with SpamAssassin (sa-learn)
by Nick Rosier 18 Aug '11

18 Aug '11

Hi, has anyone figured out how to use the dovecot-antispam plugin with sa-learn? I need to pass the username (user(a)domain.tld) to sa-learn and --ham or --spam depending on the move. I was thinking of using the CRM14 option and replace the command and arguments but cannot find anything about the ability to pass the username. Any pointers would be welcome. N.

[Dovecot] May Dovecot help in users education
by Alexandre Chapellon 18 Aug '11

18 Aug '11

Hello, I was wondering if dovecot could help me in my project to smoothly make all my users switch to TLS encrypted POP / IMAP sessions and forget about cleartext. My first idea was to setup dovecot as a POP/IMAP proxy for my mailhosts and ask dovecot to display a warning message or slowdown non TLS sessions. Is there any way to achieve this with dovecot? Does anybody have another idea smoothly force used to switch to TLS? Regards. -- <http://www.horoa.net>

[Dovecot] invalid credential using openldap
by Daminto Lie 17 Aug '11

17 Aug '11

Hi, What I have been trying to achieve is to be able to authenticate users through openLDAP while using Postfix, Dovecot as IMAP server and squirrelmail. I keep getting the following error messages when trying to login to squirrelmail 2011-08-17 12:27:59 auth(default): Info: client in: AUTH 1 PLAIN service=imap secured lip=127.0.0.1 rip=127.0.0.1 lport=143 rport=57794 resp=AGFkbWluAGFwbXg2c3Bu 2011-08-17 12:27:59 auth(default): Info: ldap(myuser,127.0.0.1): invalid credentials (given password: xxx) 2011-08-17 12:28:00 auth(default): Info: new auth connection: pid=1921 2011-08-17 12:28:01 auth(default): Info: client out: FAIL 1 user=myuser 2011-08-17 12:28:06 imap-login: Info: Aborted login (auth failed, 1 attempts): user=<myuser>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured This seems to be trivial but I just could not figure out what else went wrong. I wonder if anyone might be able to give me a bit of help as I'm still learning my way around under linux system environment. The following is what I have in /etc/dovecot/dovecot-slapd.conf hosts = localhost dn = cn=myadmin,dc=mycompany,dc=com dnpass = secrets auth_bind = yes auth_bind_userdn = cn=%u,ou=people,dc=mycompany,dc=com ldap_version = 3 base = ou=people, dc=pbj, dc=com, dc=au scope = subtree user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid user_filter = (&(objectClass=posixAccount)(uid=%u)) pass_attrs = uid=user,userPassword=password pass_filter = (&(objectClass=posixAccount)(uid=%u)) Thank you in advance

[Dovecot] Slackware Dovecot recompile with SSL/TLS question
by CopalFreak 16 Aug '11

16 Aug '11

I am having some problems and was told to ask in this list to try and get some help. When asking elsewhere, I was told that I was too verbose, so I'll try to be as brief as possible, while still including all the pertinent info. Slackware 13.1.0 Dovecot 2.0.8 Postfix 2.4.3 MySQL (virtual users) Spamassassin 3.3.1 ClamAV 0.97.1 (without Amavis) Have wild-card SSL certs and CA from GoDaddy ##"postconf -a" >> cyrus >> dovecot I compiled Dovecot without SASL support and need to re-compile it WITH SASL support, but I don't want to mess up my existing configuration. (I have it the way I want it as far as where it's installed, where the conf files are located, UID, GID settings, etc.) Dovecot 2.0.13 is out and I would prefer to use the newer version assuming it doesn't have any problems that would prevent me from using it. Is there a way to re-compile (or upgrade) so that it doesn't change any of my existing settings? I would like to be able to bring it down, do upgrade, maybe copy some config files over the defaults etc, and bring it all back up within a few minutes instead of a week of tweaking and fixing stuff. Is there a way to do something like this : stop dovecot backup all dovecot conf files ./configure CPPFLAGS=-I/path/to/openssl LDFLAGS=-L/path/to/openssl --config_dir /etc/dovecot/dovecot.conf (or something like that..not sure what it actually is) make sudo make install edit conf files to point to SSL certs start dovecot IN CASE anything goes wrong, copy old config files back and restart dovecot to make it go back the way it was (only it's using the new 2.0.13 version) any suggestions and/or tips on how-to do this would be greatly appreciated. Thanks!
