[Dovecot] Problems with dovecot/sendmail combi.
by Roger Berger 24 Aug '09

24 Aug '09

Hi, I am really stuck here. I am trying to setup imap for an external mail server. I have a freebsd server running sendmail / dovecot. I am transfering the existing mail from an exchange 2003 server to the mailserver using imapsync. This works fine, but gives errors when it tries to make a submap, also thunderbird gives an error "Mailbox doesn't allow inferior mailboxes" when I try to make a submap. I found out that it has something to do with the mbox not able to have submaps and there should be a workaround using namespaces. I tried several setups but keep getting errors. Does anybody know how to configure namespaces to allow submaps? dovecot -n # 1.2.3: /usr/local/etc/dovecot.conf # OS: FreeBSD 6.4-STABLE i386 log_path: /var/log/dovecot.log protocols: imap imaps pop3 pop3s disable_plaintext_auth: no verbose_ssl: yes 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_process_per_connection: no login_processes_count: 4 verbose_proctitle: yes first_valid_gid: 0 mail_access_groups: mail mail_location: mbox:~/mail:INBOX=/var/mail/%u 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_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: #mbox/ location: mbox:~/mail:INBOX=/var/mail/%u inbox: yes list: yes subscriptions: yes namespace: type: private separator: / location: maildir:~/mail list: yes subscriptions: yes lda: postmaster_address: postmaster(a)example.com sendmail_path: /usr/sbin/sendmail auth default: verbose: yes debug: yes debug_passwords: yes passdb: driver: pam userdb: driver: passwd mbox is in /var/mail/%u and home dir is in /home/mailusers/%u

[Dovecot] sieve vacation response
by Jure Pečar 24 Aug '09

24 Aug '09

Hello, we're implementing a dovecot 1.2.1 with sieve 0.1.7 and managesieve 0.11.7. We're having problems with creating sieve scripts so that vacation works. Our script looks like this: require ["fileinto", "vacation"]; if address :matches ["To", "Cc"] "*someone(a)example.com*" { if not header :matches "X-Spam-Status" "Yes*" { vacation :days 1 :subject "test" "autoresponder test."; keep; } } And when sent and delivered to someone(a)example.com, we get this in the log: dovecot: deliver(username): sieve: msgid=<...>: discarding vacation response for message implicitly delivered to <username(a)fqdn.hostname.com> Our final recipients are in the form of username(a)fqdn.hostname.com; it looks like this is being matched in sieve as address. But we want to match against original recipient address, not address after alias expansion. Any ideas? -- Jure Pečar http://jure.pecar.org http://f5j.eu

[Dovecot] High load with Thunderbird
by Emmanuel Seyman 24 Aug '09

24 Aug '09

Hello, all. I'm using Dovecot 1.0.15 on our internal mail server and I'm seeing a high load from one of our users. This user uses Thunderbird (with the IMAP protocol) and the load average of the server goes through the roof every once in a while. I'ld like to understand why we're seeing this and whether the blame should be put on Thunderbird or on Dovecot. Has anyone ever seen this before? Emmanuel

[Dovecot] SOT: Removing _extra_ linefeeds from MSOutlook(?) messages
by Roderick A. Anderson 24 Aug '09

24 Aug '09

I realize this is sorta off topic but my searches using Google have got me mostly no where. So I thought I'd ask here as there is a lot of _past Postfix_ mail handling issues discussed. The issue is; I have to deal with a lot of messages that come from MS Outlook users and sometimes they are replies to replies to replies ... My reading indicates it has a little to do with HTML composed messages and the format=flowed declaration. This produces messages with *lot* of extra line feeds. Makes the messages nearly unreadable -- in Thunderbird. I'm sure others have got two line (sentence) messages that took 6+ lines to display. Then when they are replies or forwards it is even more. Every line gets two NLs/CRLFs. Anyone have a suggestion of how to _strip_ multiple line feeds from a message? Is there a sieve method/way? I don't want to fiddle with all the users emails just my own. Pointers, ideas, clues? \\||/ Rod --

[Dovecot] critical X-UID reordering problem after upgrade from 1.1 to 1.2
by robh＠cs.indiana.edu 23 Aug '09

23 Aug '09

We upgraded our imap server hardware and went from dovecot 1.1.3 to 1.2.3 in the process and have been having a critical problem since. I believe I've tracked it down to X-UID reordering that dovecot seemed to do to the mbox format (I know, I know...) inboxes. The problem has manifest itself in several ways with different mail clients but the general problem is that the mail clients have gotten confused about which message is which. For example, thunderbird will display the wrong information about a message in the header listing but then show the correct data in the message display window when you actually open the message. As you can imagine, this is causing all kinds of user problems. Here is a very simplified explanation of what I'm seeing. Imagine that the inbox had 5 messages with X-UID values 1, 3, 5, 6, and 9 before the upgrade. After the upgrade the X-UIDs were reordered so these same 5 messages now might have X-UID values of 1, 2, 3, 4, and 5. Thunderbird then shows the summary information like this: Subject/Sender/Date for message 1 Subject/Sender/Date for message 2 Subject/Sender/Date for message 2 Subject/Sender/Date for message 4 Subject/Sender/Date for message 3 Now, if you actually open the 5th message it shows the right message body but the summary information is for the message that *used* to have X-UID 5 (which is now the 3rd message). So, the thunderbird cache is out of sync and I can fix it by removing the .msf file for that mailbox but, as you can imagine, the prospect of getting all the users to remove their .msf/.pst/?? cache files is daunting, to say the least. I've seen discussions about similar things happening with mbox format inboxes but they all seem to be in the context of some ancient 0.xx version of dovecot with known mbox processing bugs. But, I went from a reasonably current 1.1.3 version to 1.2.3. Right after seeing the problem, I upgraded to the just released 1.2.4 but either that didn't address the problem or, if it did, the reordering damage was already done by version 1.2.3. So, my 2 questions are: 1) Anyone know why this would have happened and whether it is a dovecot problem or something I botched? I folded all the local config changes I had made to the 1.1.3 conf file into the stock 1.2.3 conf file so they should have been identical modulo changes in the distro. And, our local config changes are really minimal. 2) Is there anything I can do now other than getting all the users to remove their .msf/.pst/etc files? It sure would be grand if there was something I could do on the server side that would magically cause all the client-side caches to be invalidated. I'm hesitant to strip the inboxes of all the X-IMAPbase and X-UID lines because I'm not sure what the ramifications of that might be. Here are some other random thoughts in case they might be related: - The old server was running 32bit RHEL4 and the new one 64bit RHEL5 - I'm using the pre-built dovecot rpms from atrpms.net - The dovecot index cache is kept in /var/cache/dovecot/indexes and I did not copy that over from the old server to the new assuming it would just be rebuilt. Any and all help is greatly appreciated! --Rob =============== dovecot -n output follows ================== # 1.2.4: /etc/dovecot.conf # OS: Linux 2.6.18-128.4.1.el5 x86_64 Red Hat Enterprise Linux Server release 5.3 (Tikanga) protocols: imaps pop3s ssl: required ssl_cert_file: /etc/mail.pem ssl_key_file: /etc/mail.pem 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 login_max_processes_count: 512 max_mail_processes: 2048 mail_max_userip_connections(default): 15 mail_max_userip_connections(imap): 15 mail_max_userip_connections(pop3): 10 first_valid_uid: 200 mail_location: mbox:~/mail/:INBOX=/var/spool/mail/%u:INDEX=/var/cache/dovecot/indexes/%u 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/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %v.%u lda: postmaster_address: postmaster(a)example.com auth default: passdb: driver: pam userdb: driver: passwd

[Dovecot] Released Sieve v0.1.12 and ManageSieve v0.11.9 for Dovecot v1.2.4
by Stephan Bosch 21 Aug '09

21 Aug '09

Hello Dovecot users, I finally managed to make new releases of Sieve and ManageSieve for the recent Dovecot v1.2.4 release. The ManageSieve release is important to match login proxy API changes in Dovecot; older versions will not compile against the new Dovecot release. The new Sieve release first includes the new date extension, which allows matching against date values in header fields and the current date-time at script execution. Changelog Sieve v0.1.12: + Testsuite: added support for testing binaries stored on disk. + Implemented the new date extension. This allows matching against date values in header fields and the current date at the time of script evaluation. Changelog ManageSieve v0.11.9: * Adjusted to changes in the Dovecot login proxy API. This release therefore depends on Dovecot v1.2.4. + Reintroduced ability to abort SASL with "*" response. Latest ManageSieve specification includes it. The releases are available as follows: Sieve: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.12.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.12.tar.gz.sig ManageSieve (package + patch): http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.9.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.9.tar.gz.s… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.4-managesieve-0.11.9.diff.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.4-managesieve-0.11.9.diff.g… Have fun testing the new releases and don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl
