[Dovecot] Problems running Dovecot 1.2.17 on AIX
by ra＠rz.uni-frankfurt.de 28 Sep '11

28 Sep '11

Hello, we have a problem getting Dovecot 1.2.17 to work on one of our AIX-Machines (AIX 5.3). Dovecot compiles fine, but if we try to run it we get strange library dependency problems such as the following: [root@localhost dovecot-test]# /local/dovecot-test/sbin/dovecot -F -c /local/dovecot-test/etc/dovecot.clients.conf Edlopen(/local/dovecot-test/lib/dovecot/imap/lib01_acl_plugin.so) failed: rtld: 0712-001 Symbol bsearch_strcmp was referenced from module /local/dovecot-test/lib/dovecot/imap/lib01_acl_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol safe_mkstemp_group was referenced from module /local/dovecot-test/lib/dovecot/imap/lib01_acl_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol mail_user_module_register was referenced from module /local/dovecot-test/lib/dovecot/imap/lib01_acl_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol dict_iterate_init was referenced from module /local/dovecot-test/lib/dovecot/imap/lib01_acl_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol dict_iterate was referenced from module /local/dovecot-test/lib/dovecot/imap/lib01_acl_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol dict_iterate_deinit was referenced from module /local/dovecot-test/lib/dovecot/imap/lib01_acl_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol i_strcmp_p was referenced from module /local/dovecot-test/lib/dovecot/imap/lib01_acl_plugin.so(), but a runtime definition of the symbol was not found. Additional errors occurred but are not reported. FCouldn't load required plugins We tried to use the compiler-script as described on the wiki (http://wiki1.dovecot.org/AixPluginsSupport) and we tried to compile dovecot with gcc instead of xlc. We even tried it on another host running AIX 5.3 but dovecot still fails with the runtime linker complaining about missing runtime definitions. Any hint/help would be appreciated. Thanks in advance Manuel

[Dovecot] Virtual Folder configuration problem.
by Terry Carmen 28 Sep '11

28 Sep '11

I'm attempting to create a virtual inbox that contains all unread messages from the user's Maildir. I created a conf file called 80-virtual.conf containing: mail_plugins = $mail_plugins virtual namespace { prefix = virtual/ separator = / location = virtual:~/Maildir/virtual } And created the /home/username/Maildir/virtual/unseen/dovecot-virtual file which contains: # ~/Maildir/virtual/unseen/dovecot-virtual * unseen However it doesn't work and the maillog file contains: dovecot: imap(username): Error: user username: Initialization failed: namespace configuration error: inbox=yes namespace missing This is with dovecot 2.0.beta6 (3156315704ef) Does anybody have any suggestions? Thanks! Terry

Hi All, Our test users re-download the mail they've left on the server when they switch from Qpopper to Dovecot. Qpopper includes the X-UIDL header - X-UIDL: X8V"!E)<"!58?"!"9C"! - on read messages.

[Dovecot] Create userdir on dovecot login --- solved
by Andreas Cieslak 27 Sep '11

27 Sep '11

Sorted out the problem, which was already solved in an older forum post of dovecot. In the file /usr/local/etc/dovecot/conf.d/auth-system.conf.ext I set Passdb { Driver = pam args = session=yes dovecot } Unfortunately this didnt work because when I log in with a user xy, the user dovecot became the owner of the userdir. When I modified the file /usr/local/etc/dovecot/conf.d/auth-system.conf.ext like this: Passdb { Driver = pam # args = session=yes dovecot } And gave anyone (for testing) the permission to write to home. That worked! At least put the ldap-users in a group and gave that group writing permissions to home. Finished! -----Ursprüngliche Nachricht----- Von: dovecot-bounces(a)dovecot.org [mailto:dovecot-bounces@dovecot.org] Im Auftrag von Andreas Cieslak Gesendet: Donnerstag, 22. September 2011 15:41 An: dovecot(a)dovecot.org Betreff: [Dovecot] Create userdir on dovecot login Hi List, I am trying to set up automated userdir-creation on login via squirrelmail or email-client with a dovecot backend. The users are first imported on an openldap directory on the same server as the dovecot runs on. Authentication on the dovecot mail system via pam_ldap works properly. Tried already to integrate some advices from the dovecot wiki like Passdb { Driver = pam args = session=yes dovecot } But the homedir creation works only when the user logs onto the machine. When I try to log in via Squirrel on the dovecot no homedir is created and there is following message in the logs: auth: Error: pam(cieslak,193.175.157.121): pam_open_session() failed: Permission denied I think its something about the user rights, but dont really know where to search for the needle Here is the config of my environment root@server:/home# dovecot -n # 2.0.13: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-686 i686 Debian 6.0.2 auth_debug = yes auth_mechanisms = login plain auth_verbose = yes first_valid_uid = 1000 hostname = server info_log_path = /var/log/dovecot-info last_valid_uid = 10000 listen = * log_path = /var/log/dovecot mail_access_groups = mail mail_debug = yes mail_full_filesystem_access = yes mail_location = maildir:~/Maildir mbox_write_locks = fcntl passdb { args = session=yes dovecot driver = pam } postmaster_address = mailaddress service auth-worker { group = shadow user = $default_internal_user } service auth { user = $default_internal_user } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } process_min_avail = 0 service_count = 0 vsz_limit = 256 M } service lmtp { unix_listener lmtp { mode = 0666 } } service pop3-login { inet_listener pop3s { port = 995 ssl = yes } } ssl_ca = </usr/local/etc/dovecot/ca ssl_cert = </usr/local/etc/dovecot/crt ssl_key = </usr/local/etc/dovecot/key userdb { driver = passwd } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } dovecot --version 2.0.13 The configuration of the pam module /etc/pam.d/dovecot looks like @include common-auth @include common-account @include common-session The common session has the line session required pam_mkhomedir.so skel=/etc/skel umask=0077 I would appreciate any hints.

[Dovecot] deliver agent and index/control files
by Nerijus Kislauskas 27 Sep '11

27 Sep '11

Hi Timo and others, We use Dovecot in Kaunas University of Technology in Lithuania. For now our LDA is Postfix and POP/IMAP server is Dovecot. We would like to implement dovecot deliver as LDA. Everything is ok exept one small thing: deliver is creating dovecot.index.log in wrong place In dovecot config files we have: ... mail_location = maildir:/var/mail/%Ln:INDEX=/var/indexes/%Ln:CONTROL=/var/indexes/%Ln ... As you can see, mail and index/control files are in different partitions. and deliver log: deliver(nerijus.kislauskas(a)ktu.lt): maildir: data=/var/mail/nerkisl deliver(nerijus.kislauskas(a)ktu.lt): maildir++: root=/var/mail/nerkisl, index=, control=, inbox=/var/mail/nerkisl That is why dovecot.index.log is created in /var/mail/nerkisl, and not in /var/indexes/nerkisl. How can we fix this? -- Sincerely, Nerijus Kislauskas KTU ITPI, LitNET NOC Studentu g. 48a - 101, Kaunas tel.: (8~37) 30 06 45 mob. tel.: 8-614-93889 e-mail.: nerijus.kislauskas(a)ktu.lt

[Dovecot] Subscription File
by Carlos Mennens 26 Sep '11

26 Sep '11

I had a use lose 20 folders on their mail account. I was able to pull them back from a restore and dumped them all back on the server in her Maildir. The problem is she doesn't see them on her Thunderbird or Outlook client. I checked to make sure I put them back into the correct directory and I did as well as verify permissions aren't weird. I then noticed a file called 'subscriptions' in her Maildir directory. She appears to only be seeing folders that are listed in this 'subscriptions' file. My question is how do I update this file? If I delete it, will Dovecot re-generate the file with the correct subscription entries? I don't understand what to do but I'm hoping I don't have to edit the file by hand...that seems way too cumbersome.

[Dovecot] how to disable quota for second namespace?
by Udo Lembke 26 Sep '11

26 Sep '11

Hi all, I have a second namespace as archive, where no quota should be active (work with type = shared). But if I change the type to private the quota will allways count. My dovecot version is the 2.0.13. I have tried things like this: plugin { quota_rule = *:storage=500M quota_rule2 = Trash:storage=+100M quota_rule3 = Sent:storage=+50M quota_rule4 = ns=archiv/%u/:ignore } It's also doesn't work with "quota_rule4 = archiv/%u/:ignore" The namespace: namespace { type = private separator = / prefix = "archiv/%u/" location = maildir:/var/data/archiv/%d/%n:INDEX=/var/data/indexes/archiv/%u:LAYOUT=fs inbox = no hidden = no subscriptions = no list = yes } Even if I define the namespace for quota I see the quota-value also in the "root": plugin { quota = maildir:User quota quota2 = maildir:Archiv quota:ns=archiv/%u/ } doveadm quota get -u test(a)example.com Quota name Type Value Limit % User quota STORAGE 1587135 512000 309 User quota MESSAGE 13346 - 0 Archiv quota STORAGE 1359379 - 0 Archiv quota MESSAGE 10577 - 0 du -ks /var/data/mail/example.com/test 234364 /var/data/mail/example.com/test du -ks /var/data/archiv/example.com/test 1383792 /var/data/archiv/example.com/test Now is the big question, how can I reach such an output? doveadm quota get -u test(a)example.com Quota name Type Value Limit % User quota STORAGE 227756 512000 44 User quota MESSAGE 2769 - 0 Archiv quota STORAGE 1359379 - 0 Archiv quota MESSAGE 10577 - 0 I can't believe that's only possible with a shared namespace, or? Any hints are welcome. Best regards Udo

[Dovecot] "doveadm log reopen" don't reopen seperate lmtp log
by Henrik Larsson 25 Sep '11

25 Sep '11

Dear all I have setup separate pop3/imap log "/var/log/dovecot" and lmtp delivery log "/var/log/dovecot-deliver". After rotating logfiles, i run "doveadm log reopen". I see that my pop3/imap log "/var/log/dovecot" is used straight away, but my lmpt log "/var/log/dovecot-deliver" isn't used at first. After some time, usually a few minutes, logs are being written to this file anyway. But if I compare this to my maillog, it misses some deliveries just after the log rotation. Is there any problems with this configuration that should be corrected? --cut-- # doveconf -n # 2.0.15: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.2-STABLE amd64 auth_mechanisms = plain login digest-md5 cram-md5 first_valid_uid = 125 hostname = mail.larsson.it listen = * log_path = /var/log/dovecot mail_plugins = fts fts_squat zlib mail_privileged_group = postfix mail_temp_dir = /var/db/dovecot managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date namespace { inbox = yes location = prefix = separator = . type = private } namespace { hidden = yes inbox = no list = no location = prefix = INBOX. separator = . type = private } passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { fts = squat fts_squat = partial=4 full=10 sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap pop3 lmtp sieve service auth-worker { user = $default_internal_user } service auth { unix_listener /home/mail/postfix/private/auth { group = postfix mode = 0666 user = postfix } } service lmtp { executable = lmtp -L unix_listener /home/mail/postfix/private/dovecot-lmtp { group = postfix mode = 0660 user = postfix } } ssl_cert = </etc/ssl/mail-chained.crt ssl_key = </etc/ssl/mail.key userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lmtp { log_path = /var/log/dovecot-deliver mail_plugins = fts fts_squat zlib sieve } protocol lda { mail_plugins = fts fts_squat zlib sieve } protocol imap { mail_plugins = fts fts_squat zlib imap_zlib } --cut-- Best regards Henrik Larsson

[Dovecot] dsync doubts
by Piotr NetExpert 24 Sep '11

24 Sep '11

Hi everyone, I want to backup mailboxes to another server. A usage information for dsync says "... <remote dsync command>". Does it mean I need dsync installed on the other server too? Now when I try to run dsync I receive: # dsync -v -D -u abc backup ssh user(a)other.server dsync(username): Debug: Effective uid=123, gid=123, home=/path/abc dsync(username): Debug: maildir++: root=/path/abc, index=, control=, inbox=/path/abc dsync-local(abc): Debug: Namespace : Using permissions from /path/abc: mode=0700 gid=-1 Password: server: not found dsync-local(abc): Error: read() from worker server failed: EOF What could be wrong? How can I check what it wants to do and cannot? I cannot find more information I need in a wiki page of dsync. -- pozdrawiam Piotr Szafarczyk http://www.netexpert.pl

[Dovecot] tiny doc bug report
by Jeff Rogers 23 Sep '11

23 Sep '11

First timer, I'm installing dovecot-2.0.15. I ran configure; make; sudo make install The INSTALL file then says: --- Rename configuration file: mv /usr/local/etc/dovecot-example.conf /usr/local/etc/dovecot.conf Read through, and make needed modifications. --- The example configuration file is not installed in that location. Presumably it is now installed as /usr/local/share/doc/dovecot/example-config/dovecot.conf Unless this path difference is a quirk of my local system, the INSTALL directions should be fixed to avoid confusion. Thanks, -J
