[Dovecot] cyrus2courier or cyrus2maildir.py, which to choose?
by Steinar Bang 09 Sep '08

What's the best utility to use to convert mail folders from a cyrus 2.2.13-10, on a debian 4.0 Etch system, to folders that can be used by dovecot? The http://wiki.dovecot.org/Migration/Cyrus page isn't too clear on what's the difference. cyrus2courier says "It should be able to preserve message UIDs, flags and 26 first keywords." cyrus2maildir.py says "preserves delivery timestamps and \Seen flags." But does that means that what cyrus2maildir.py preserves is in addition to what cyrus2courier preserves? Or is what cyrus2maildir preserves a subset of what cyrus2courier preserves? Thanx! - Steinar

[Dovecot] Error in Sieve + Dovecot 1.1.3
by Allan Cassaro 09 Sep '08

09 Sep '08

Hi, when I upgrade my dovecot to lastest version (from 1.1.1 to 1.1.3) and sieve plugins I discover a little problem in deliver (LDA) or in Sieve interface. With version 1.1.1 I have this in my dovecot.conf (and works fine) protocol lda { postmaster_address = root(a)mct.gov.br hostname = faraday.mct.gov.br mail_debug = no mail_plugins = cmusieve quota sieve_global_dir = /etc/dovecot/scriptssieve/ sieve = /home/%u/.dovecot.sieve } When I upgrade, the deliver/LDA stop to work and show me this message (in logs): deliver(acassaro): cmusieve: /home/%u/.dovecot.sieve doesn't exist So, when I change the "sieve" parameter, everything works fine again. protocol lda { postmaster_address = root(a)mct.gov.br hostname = faraday.mct.gov.br mail_debug = no mail_plugins = cmusieve quota sieve_global_dir = /etc/dovecot/scriptssieve/ sieve = ~/.dovecot.sieve } So, I don't know if this error is on LDA or Sieve patch (probably in sieve patch) Versions: dovecot-1.1.3 dovecot-sieve-1.1.5 dovecot-1.1-managesieve-0.10.3 dovecot-1.1.2-managesieve-0.10.3.diff Regards.

[Dovecot] Thunderbird, subscriptions, and upgrade to 1.1.3
by Jack Stewart 08 Sep '08

08 Sep '08

Hi, I've upgraded from 1.0.7 to 1.1.3. When I did this, my Thunderbird lost its brain and did not show some subscribed folders. squirrelmail also seemed to have issues. Applemail and mutt were fine. The configuration output is below. Hopefully this is just me and just random bizarreness. There wasn't a problem in 1.0.7 but I could have been caught in mid-upgrade. Thunderbird did not seem to update the subscription file (or at least I could not find the one it thought it was using). Any pointers are appreciated. Thanks in advance. ---Jack /opt/dovecot/sbin/dovecot -c /etc/dovecot.conf -n # 1.1.3: /etc/dovecot.conf Warning: fd limit 1024 is lower than what Dovecot can use under full load (more than 6144).

[Dovecot] zlib plugin nad moving mails, bug?
by Mateusz Kijowski 08 Sep '08

08 Sep '08

Hi, Recently I gzipped mails older than 30 days in our users' maildirs. I used find and gzip. Gzip added 'Z' at the end of the filename and everything seemed to work fine, users did not notice any difference in performance (yet :-), and I saved about 30% of our mail storage space. There seems to be a problem when moving gzipped messages from one folder to another though. Dovecot drops the Z flag, moved messages are not processed by the zlib plugin and email clients end up showing garbage. Is there something wrong with my config, or did I encounter a bug? dovecot -n follows: # 1.0.13: /etc/dovecot/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot.log protocols: imap imaps pop3s ssl_ca_file: /etc/certs/certum-chain.crt ssl_cert_file: /etc/certs/wild.dfqs.pl.crt ssl_key_file: /etc/certs/wild.dfqs.pl.key ssl_cipher_list: ALL:!LOW:!MEDIUM login_dir: /var/run/dovecot/login login_executable(default): /usr/lib64/dovecot/imap-login login_executable(imap): /usr/lib64/dovecot/imap-login login_executable(pop3): /usr/lib64/dovecot/pop3-login login_greeting: imap.dfqs.pl ready. login_process_per_connection: no login_processes_count: 5 login_max_processes_count: 32 max_mail_processes: 4096 verbose_proctitle: yes mail_location: maildir:~/mail:INDEX=/var/lib/dovecot/indexes/%Ln mail_debug: yes maildir_copy_with_hardlinks: yes maildir_copy_preserve_filename: yes mail_executable(default): /usr/local/lib64/dovecot-post-login-imap.sh mail_executable(imap): /usr/local/lib64/dovecot-post-login-imap.sh mail_executable(pop3): /usr/local/lib64/dovecot-post-login-pop3.sh mail_plugins(default): imap_quota trash quota acl zlib mail_plugins(imap): imap_quota trash quota acl zlib mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib64/dovecot/plugins/imap mail_plugin_dir(imap): /usr/lib64/dovecot/plugins/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/plugins/pop3 mail_log_max_lines_per_sec: 0 imap_client_workarounds(default): outlook-idle tb-extra-mailbox-sep imap_client_workarounds(imap): outlook-idle tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh namespace: type: private separator: / inbox: yes namespace: type: public separator: / prefix: Public/ location: maildir:/var/vmail/Public:CONTROL=~/Public/control:INDEX=~/Public/index namespace: type: shared separator: / prefix: Shared/ location: maildir:/var/vmail/Shared:CONTROL=~/Shared/control:INDEX=~/Shared/index auth default: verbose: yes debug: yes worker_max_count: 512 passdb: driver: pam args: dovecot userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 user: root group: vmail master: path: /var/run/dovecot/auth-master mode: 432 user: root group: vmail plugin: quota: maildir:storage=12582912:ignore=Trash acl: vfile: trash: /etc/dovecot/dovecot-trash.conf

[Dovecot] v1.1.3 release candidate
by Timo Sirainen 08 Sep '08

08 Sep '08

I thought about making a release now, but I'll probably do some more fixes tomorrow, so here's a prerelease for everyone to test. :) If you see any bugs with this (old or new), please report. http://dovecot.org/tmp/dovecot-1.1.3-rc.tar.gz Important changes are: * mail_max_userip_connections limit no longer applies to master user logins. + login_log_format_elements: Added %k to show SSL protocol/cipher information. Not included by default. + imap/pop3-proxy: If auth_verbose=yes, log proxy login failures. + deliver: Added -s parameter to autosubscribe to autocreated mailboxes. - message parser fixes - hopefully fixes an infinite looping problem - SORT: One more assert-crashfix when renumbering index sort IDs. - mbox: Saving may have truncated the mail being saved - mbox: Several other bugfixes - mail_full_filesystem_access=yes was broken when listing mailboxes (it still is with maildir++ layout). - maildirlock utility was somewhat broken - zlib plugin: bzip2 support was somewhat broken - NFS: Make sure writing to files via output streams don't assert-crash when write() returns only partial success.

Hello all. I'm have this problem: I'm want auth users by "uid" filed but this filed uniq only in one LDAP container. So im what to tell dovecot were to look some "uid" by "mail" filed of this user. Can im do this: pass_filter = (&(objectClass=mailUser)(mail=*@%d)(uid=%n)) Will this construction work? -- Best regards, Proskurin Kirill

[Dovecot] Error starting dovecot
by Diego Ledesma 08 Sep '08

08 Sep '08

Hello, I have a linux system (Ubuntu 7.04 server edition) running Postfix 2.3.8 Today i installed Dovecot through apt-get (got version 1.0.rc17 installed) and configured it to do sasl auth only, (i already have other pop3,smtp and imap servers running) following the howto's at dovecot.org The thing is that if i try to start dovecot or run dovecot -n i get this message: Error: Can't use mail executable /usr/lib/dovecot/imap: No such file or directory That directory does not exist but why should it if i don't want to run dovecot as imap? I only installed dovecot-common package. Also, i setted protocols to "none". Does anyone know why i get that error message? One last comment. Before installing dovecot on the production mail server i installed it on my laptop's linux (Ubuntu 8.04 LTS) for testing purposes. The testing mail server runs Postfix 2.5.1 and Dovecot 1.0.10 and in this case Dovecot runs fine (the /usr/lib/dovecot/imap directory does also not exist and dovecot.conf is configured exactly on both servers). This are the uncommented parts of dovecot.conf #Only use dovecot-auth protocols = none disable_plaintext_auth = no log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = maildir:~/Maildir mail_privileged_group = mail protocol imap { } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } auth default { mechanisms = plain login passdb passwd-file { args = /etc/passwd.dovecot } passdb pam { } userdb passwd { } user = root socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } dict { } plugin { } ---- Any help is greatly appreciated. Thanks. Diego.

Sorry, bounced this the first time ;( Darren I'd happily switched to a real cert if I knew that this was the problem. Are you using the cert actually on the phone to validate its identity? I have the org unit set slightly differently on my fake CA and the phone to make netscape derived browsers happy. The trouble is that I'm not getting a useful enough error message from anyone to diagnose problem. I have also considered putting my fake CA cert on the phone to see if that would make it happier, Darren >Charles Marcus wrote: >>You're not using self-signed certs by any chance? >> >> > >I have had good success using the cheapo certs from GoDaddy - they >offer a cert with multiple Alt names so you can connect using a >variety of server names.
