[Dovecot] dovecot and tcpwrappers
by Kees Lemmens 23 Aug '11

23 Aug '11

Hi, I used dovecot 1.x for quite a while and it worked fine. However, I used it through inetd and used hosts.allow/deny to restrict access to only certain groups of systems. Since yesterday I have dovecot 2.0.13. But in version 2.0.13 it seems that starting using inetd doesn't work anymore : I only get a strange error message if I try to connect using telnet : telnet localhost imap doveconf: Fatal: execvp(imap-login) failed: No such file or directory I tried a lot of things but couldn't get it going over inetd so I decided to start it directly using an init script, also because you say in the wiki this is (now) the preferred method. That indeed works fine, but I realised today that dovecot is now completely ignoring all my hosts.allow/deny settings and so is worldwide accessible ! Is dovecot indeed ignoring hosts.allow/deny ? And if so, how can I have the same amount of protection as I previously had with dovecot 1.x over inetd ? BTW: I tried to post on the mailinglist but it seems I can't access them it the moment, altough I did subscribe and login. Is there anything wrong ? Thanks for your reply ! -- With best regards, Kees Lemmens. ----------------------------------------------------------------------- Delft Institute of Applied Mathematics (DIAM), Faculty Electrical Engineering, Mathematics and Computer Science, Delft University of Technology, Delft, The Netherlands,

[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

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? Sample log entires for my user matching on the message: Aug 20 16:28:36 host2 dovecot: imap(soho.steve): Disconnected: Too many invalid IMAP commands. bytes=3242/14672 Aug 20 16:28:43 host2 dovecot: imap(soho.steve): Disconnected: Too many invalid IMAP commands. bytes=14219/231327 Aug 20 16:29:50 host2 dovecot: imap(soho.steve): Disconnected: Too many invalid IMAP commands. bytes=640/1968 Aug 20 16:29:57 host2 dovecot: imap(soho.steve): Disconnected: Too many invalid IMAP commands. bytes=3521/2024 Aug 20 16:30:04 host2 dovecot: imap(soho.steve): Disconnected: Too many invalid IMAP commands. bytes=6690/3415 Aug 20 16:30:05 host2 dovecot: imap(soho.steve): Disconnected: Too many invalid IMAP commands. bytes=5098/15294 Aug 20 16:30:06 host2 dovecot: imap(soho.steve): Disconnected: Too many invalid IMAP commands. bytes=706/15684 Steve

[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.
