[Dovecot] thunderbird and subscriptions with sieve
by Kristen J. Webb 02 Sep '11

02 Sep '11

Hi All, I'm a newbie trying to move mail out of my ISP onto a ubuntu (lucid) dovecot 1.2.9 server. Is there any way to automatically add folders created by sieve (GNU Mailutils 2.1) to the subscriptions file for a user? I'm currently testing spam, and if sieve created the folder with the first message, the thunderbird user does not see the new folder. Even more interesting, if the user then tries to create the Spam directory it thunderbird seems to quietly ignore the request and the user still cannot see the folder, but I digress... I can manually subscribe with thunderbird, but this won't scale for more complex sieve later by making the user responsible for finding everything. I can turn off subscription view in advanced settings on thunderbird, but we are trying to wean ourselves of of individual mail clients and I don't want to have to test this everywhere. Many thanks in advance! Kris -- Mr. Kristen J. Webb Teradactyl LLC. PHONE: 1-505-242-1091 EMAIL: kwebb(a)teradactyl.com VISIT: http://www.teradactyl.com Home of the True incremental Backup System

Hi, I received the following error from mail.log Aug 31 13:50:57 server1 dovecot: IMAP(mike_lee): mkdir(/home/mike_lee/Maildir/.INBOX.Sent/cur) failed: Permission denied (euid=1004 egid=1003(companyusergroup) missing +w perm: /home) What I have tried to do is changing the permission for /home by typing "sudo chmod 755 /home" and this does not work. What does it mean by missing +w perm: /home? and wonder how to get around it? This is what I have in main.cf from Postfix myhostname = server1 myorigin = /etc/mailname relayhost = mynetworks = 127.0.0.0/8, 192.168.1.0/24 inet_interfaces = all inet_protocols = ipv4 home_mailbox = Maildir/ smtpd_sasl_type = dovecot #smtpd_sasl_path = private/auth-client smtpd_sasl_path = private/auth smtpd_sasl_auth_enable = yes smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination #smtpd_sender_login_maps = ldap:/etc/postfix/ldap_senders.cf broken_sasl_auth_clients = yes #dovecot_destination_recipient_limit = 1 debug_peer_list = 127.0.0.1 debug_peer_level = 5 Any help is very much appreciated.

"Body message"; } Is implemented :addresses ["*"] in later 1.2 version ? Where is problem? What i must to do to get this thing working ? Upgrading to version 2.x isn't solution for me now. Thank you for advices and help. -- Lampa

[Dovecot] Segmentation fault in dovecot director lmtp service
by Reinhard Vicinus 01 Sep '11

01 Sep '11

Hi, the lmtp service of our dovecot director installation quits with a segmentation fault if a lot of mails are simultaneously delivered. For example if the postfix mailqueue is filled (for whatever reason) and postqueue -f is run the lmtp service quits with a segmentation fault: Program terminated with signal 11, Segmentation fault. #0 o_stream_cork (stream=0x0) at ostream.c:75 75 if (unlikely(stream->closed)) (gdb) backtrace #0 o_stream_cork (stream=0x0) at ostream.c:75 #1 0x00007fa6e6af45d9 in lmtp_client_send_more (client=0x2435870) at lmtp-client.c:596 #2 0x0000000002434170 in ??

The configuration of the dovecot director installation is attached. Please let me know if i shall provide any more information or test something. Kind regards Reinhard

[Dovecot] Crash in director/lmtp-proxy (lmtp_proxy_output_timeout)
by Jan-Frode Myklebust 01 Sep '11

FYI, we saw one panic on our director/lmtp-proxy yesterday. It's running dovecot v2.0.13, so it very well might have been fixed already.., but here it is anyway: Aug 31 11:33:31 loadbalancer1 dovecot:: lmtp(4119): Panic: file lmtp-proxy.c: line 370 (lmtp_proxy_output_timeout): assertion failed: (proxy->data_input->eof) Aug 31 11:33:31 loadbalancer1 dovecot:: lmtp(4119): Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0 [0x3aabc3bb70] -> /usr/lib64/dovecot/libdovecot.so.0 [0x3aabc3bbc6] -> /usr/lib64/dovecot/libdovecot.so.0 [0x3aabc3b083] -> dovecot/lmtp [0x406c90] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handle_timeouts+0xcd) [0x3aabc46a8d] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handler_run+0x68) [0x3aabc47a48] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_run+0x2d) [0x3aabc466fd] -> /usr/lib64/dovecot/libdovecot.so.0(master_service_run+0x13) [0x3aabc34fe3] -> dovecot/lmtp(main+0x144) [0x404034] -> /lib64/libc.so.6(__libc_start_main+0xf4) [0x32ae81d994] -> dovecot/lmtp [0x403e39] Aug 31 11:33:31 loadbalancer1 dovecot:: master: Error: service(lmtp): child 4119 killed with signal 6 (core dumps disabled) On postfix side at the same time, we saw a few different messages about: postfix/lmtp[5178]:: 849FD1C024: lost connection with loadbalancers.example.com[192.168.42.15] while sending end of data -- message may be sent more than once so I suspect this crash took down all active lmtp-proxyed connections. -jf

[Dovecot] lmtp bouncing -- Invalid parameters (in reply to MAIL FROM command)
by Jan-Frode Myklebust 01 Sep '11

01 Sep '11

I just configured postfix' virtual_transport to point at my dovecot director, but am seeing occational problems like this: Aug 31 11:50:06 smtpgw postfix/lmtp[5339]: 69E2F5410D: to=<email(a)example.net>, relay=loadbalancers.example.net[192.168.42.17]:24, delay=0.15, delays=0.14/0.01/0/0, dsn=5.5.4, status=bounced (host loadbalancers.example.net[192.168.42.17] said: 501 5.5.4 Invalid parameters (in reply to MAIL FROM command)) but can't find anything interesting in the dovecot logs.. Anybody have ideas for how to make postfix play nice with dovecot's lmtp ? smtpgws% rpm -q postfix postfix-2.3.3-2.1.el5_2 loadbalancers% rpm -q dovecot dovecot-2.0.13-2 backendmailstorers% rpm -q dovecot dovecot-2.0.13-2 -jf

[Dovecot] Proprietary mail storage.
by Alex Cherniak 01 Sep '11

01 Sep '11

I have a large existing read-only collection of mails packaged in individual zip files as <rfc822 file>+<some additional info>. Is it possible (and how difficult) to create a proprietary plugin (like gzip) which will open a zip file, extract mail and pass it back to Dovecot? Where do I start? If plugin is not the right approach, what is? Another question is how will this affect Dovecot performance and how to avoid any significant degradation. Any help is appreciated.Thanks.

Previously when I was using Postfix to deliver the mails, I could change the maildirloc in the DB - but I’m not sure how to accomplish this with dovecot LDA. > > I'm using Postfixadmin to manage users and have server alias-domains. All mail sent to an alias-domain is delivered to the other domain. Quite easy if you've got postfixadmin already setup. Otherwise I think you could configure virtual_alias_maps in postfix to something like hash:virtual_domains virtual_domains: @example.net @example.com N.

[Dovecot] sorting order changed during migration from courier
by Micah Anderson 31 Aug '11

31 Aug '11

Hello, I've been working to migrate to dovecot (debian stable: 1:1.2.15-7) from courier (debian old-stable: 4.4.0-2). I've setup everything and migrated a test user over to the new system, and ran the courier-dovecot-migrate.pl script. The user is using alpine (the free version of pine) and their sort order changed on move to dovecot. Originally it was the default in alpine, which is to sort based on arrival. If he changes the sort order in alpine to sort based on date, then things are back to how he expects it. I noticed that there are no known issues with pine (http://wiki.dovecot.org/Clients#Pine) Ideally, I would prefer if all the users who are migrated aren't presented with a different sort order than they were used to, as the support burden will be quite high. What is it about this migration that could have caused that, and more importantly, how can I fix it? I moved the mail from the original system to this system via rsync -a. The old system was an i686 machine and ext3, this new one is amd64 and ext4. thanks for any ideas! micah # dovecot -n # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.2 protocols: imap imaps pop3 pop3s disable_plaintext_auth: no verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_greeting: howdy, ready. login_processes_count: 10 login_max_processes_count: 256 first_valid_uid: 8 last_valid_uid: 8 first_valid_gid: 8 last_valid_gid: 8 mail_uid: 8 mail_gid: 8 mail_location: maildir:~/ maildir_copy_preserve_filename: yes maildir_very_dirty_syncs: yes mbox_write_locks: fcntl dotlock mail_executable(default): /maildir/postlogin_imap mail_executable(imap): /maildir/postlogin_imap mail_executable(pop3): /maildir/postlogin_pop mail_process_size: 512 mail_plugins(default): expire quota imap_quota mail_plugins(imap): expire quota imap_quota mail_plugins(pop3): expire quota mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 imap_client_workarounds(default): tb-extra-mailbox-sep delay-newmail imap_client_workarounds(imap): tb-extra-mailbox-sep delay-newmail 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: INBOX. inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)riseup.net auth default: default_realm: riseup.net verbose: yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: prefetch dict: expire: mysql:/etc/dovecot/dovecot-dict-expire.conf --
