[Dovecot] basic understanding of imap in dovecot
by dovecot＠paz.bz 24 Dec '09

24 Dec '09

I have always used a pop3 daemon, and switching to dovecot has been my introduction to imap. Imap is foreign to me. I am wondering if I am a little off-track here, and would like some clarification. My MTA (exim) delivers email to: /mail/user dovecot, sucks that mail from /mail/user TO /home/user/mail/<filenamesoffolders> dovecot IMAP further uses /home/user/mail/.imap/folders/{.index / .index.cache / .index.log} the mail folder which exim uses doesn't seem to get emptied by dovecot when it sucks the email into /home/user/mail/<filenamesoffolders> when using IMAP. If POP3 is used via dovecot, then it appears that the interaction is directly to the original exim folder and that it does indeed empty (or at least it has the "FOLDER INTERNAL DATA" entry). I suppose my question is, is there a way to have dovecot empty/parse the original exim mailbox so that the customer email isn't sitting in two spots, taking up double the space. This would be in the IMAP environment only, as POP3 seems to be fine. Any online references available to help a newbee understand IMAP? Thanks!

Hi Timo, I've replaced a mdbox, as long Thunderbird was connected. The result is attached.

[Dovecot] Permissions errors while reading messages via IMAP
by Geoff Sweet 24 Dec '09

24 Dec '09

Greetings all, I have been trying to setup a new system using Postfix and Dovecot to manage email for a bunch of virtual domains. So far everything is great, and I am now at the point where I am trying to build a webmail interface for the system. I'm using RoundCube for now. The tutorial I have been working from is here: http://workaround.org/articles/ispmail-etch/ Which seems to be a decent enough read. At this point I can login without issue but I can't see any mail messages. When I login, dovecot throws errors like this: Dec 23 12:08:49 mail1 dovecot: auth(default): client out: OK 1 user=geoff.sweet(a)test.com Dec 23 12:08:49 mail1 dovecot: auth(default): master in: REQUEST 1 4312 1 Dec 23 12:08:49 mail1 dovecot: auth(default): master out: USER 1 geoff.sweet(a)test.com uid=5000 gid=5000 home=/home/vmail/test.com/geoff.sweet Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): Effective uid=5000, gid=5000, home=/home/vmail/test.com/geoff.sweet Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): maildir: data=/home/vmail/test.com/geoff.sweet/Maildir Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): maildir++: root=/home/vmail/test.com/geoff.sweet/Maildir, index=, control=, inbox=/home/vmail/test.com/geoff.sweet/Maildir Dec 23 12:08:49 mail1 dovecot: imap-login: Login: user=<geoff.sweet(a)test.com>, method=PLAIN, rip=192.168.20.11, lip=192.168.20.12 Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): Disconnected: Logged out bytes=39/431 Dec 23 12:08:49 mail1 dovecot: auth(default): new auth connection: pid=4315 Dec 23 12:08:49 mail1 dovecot: auth-worker(default): sql(geoff.sweet(a)test.com,192.168.20.11): query: SELECT email as user, password FROM view_mailboxes WHERE email='geoff.sweet(a)test.com'; Dec 23 12:08:49 mail1 dovecot: auth(default): client in: AUTH 1 PLAIN service=imap lip=192.168.20.12 rip=192.168.20.11 lport=143 rport=43878 resp=AGdlb2ZmLnN3ZWV0QHdob290aXMuY29tAGJvYjEyMzQ1 Dec 23 12:08:49 mail1 dovecot: auth(default): client out: OK 1 user=geoff.sweet(a)test.com Dec 23 12:08:49 mail1 dovecot: auth(default): master in: REQUEST 2 4311 1 Dec 23 12:08:49 mail1 dovecot: auth(default): master out: USER 2 geoff.sweet(a)test.com uid=5000 gid=5000 home=/home/vmail/test.com/geoff.sweet Dec 23 12:08:49 mail1 dovecot: imap-login: Login: user=<geoff.sweet(a)test.com>, method=PLAIN, rip=192.168.20.11, lip=192.168.20.12 Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): Effective uid=5000, gid=5000, home=/home/vmail/test.com/geoff.sweet Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): maildir: data=/home/vmail/test.com/geoff.sweet/Maildir Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): maildir++: root=/home/vmail/test.com/geoff.sweet/Maildir, index=, control=, inbox=/home/vmail/test.com/geoff.sweet/Maildir Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): Namespace : Using permissions from /home/vmail/test.com/geoff.sweet/Maildir: mode=0700 gid=-1 Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): open(/home/vmail/test.com/geoff.sweet/Maildir/dovecot.index.log) failed: Permission denied (euid=5000(vmail) egid=5000(vmail) missing +r perm: /home/vmail/test.com/geoff.sweet/Maildir/dovecot.index.log) Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): open(/home/vmail/test.com/geoff.sweet/Maildir/dovecot-uidlist) failed: Permission denied Dec 23 12:08:49 mail1 last message repeated 2 times There is some permission issue that allows dovecot to deliver email to the /home/vmail location (I dislike this location and want to change it) via the dovecot LDA process, but then not be able to read it when accessed via IMAP.

[Dovecot] imap-login crashes after upgrade to Dovecot 1.2.8 Linux 64-bit
by Chris Wakelin 23 Dec '09

23 Dec '09

Hi all, We moved our Dovecot installation first of all to have all folders and inboxes on NetApps via NFS (with indexes local) then from a physical Solaris 8 4-way UltraSparc server running Dovecot 1.2.5 (32-bit) to a virtualised Ubuntu 8.04 64-bit server with a single virtual processor (in VMWare ESX 3.5) running Dovecot 1.2.8 (64-bit). Since the change, many of our users have experienced random disconnections when proxied in imap-login (either using the internal SSL proxy, or to an external IMAP server) and the error logs contain things like: > Dec 18 00:27:58 imap-login: Info: Disconnected: Connection queue full (auth failed, 1 attempts): user=<user0>, method=PLAIN, rip=<ip0>, lip=134.225.32.156, TLS > Dec 18 00:27:58 imap-login: Panic: file ioloop.c: line 39 (io_add): assertion failed: (fd >= 0) > Dec 18 00:27:58 IMAP 9486 <user1> <ip1> : Info: Connection closed bytes=224/1753 > Dec 18 00:27:58 IMAP 10116 <user2> <ip2> : Info: Connection closed bytes=82/707 ... > Dec 18 00:27:58 IMAP 10296 <user3> <ip3> : Info: Disconnected in IDLE bytes=44/435 > Dec 18 00:27:58 IMAP 10298 <user3> <ip3> : Info: Disconnected in IDLE bytes=263/1662 > Dec 18 00:27:58 dovecot: Error: child 5124 (login) killed with signal 6 (core dumped) (latest ip=<ip0>) > Dec 18 00:27:58 imap-login: Info: Aborted login (no auth attempts): rip=<ip0>, lip=134.225.32.156, TLS: Disconnected and a backtrace gives: > (gdb) bt > #0 0x00007ff1030ad095 in raise () from /lib/libc.so.6 > #1 0x00007ff1030aeaf0 in abort () from /lib/libc.so.6 > #2 0x00000000004112d5 in default_fatal_finish (type=<value optimized out>, status=0) at failures.c:160 > #3 0x0000000000411333 in i_internal_fatal_handler (type=LOG_TYPE_PANIC, status=0, fmt=<value optimized out>, args=<value optimized out>) at failures.c:443 > #4 0x0000000000410996 in i_panic (format=0x6 <Address 0x6 out of bounds>) at failures.c:207 > #5 0x000000000041420e in io_add (fd=-1, condition=IO_READ, callback=0x404db0 <client_input>, context=0x6af000) at ioloop.c:39 > #6 0x00000000004059db in client_auth_failed (client=0x6af000, nodelay=true) at client-authenticate.c:103 > #7 0x0000000000405e07 in client_handle_args (client=0x6af000, args=<value optimized out>, success=true, nodelay_r=0x7fff571009af) > at client-authenticate.c:198 > #8 0x0000000000406214 in sasl_callback (_client=0x6af000, reply=SASL_SERVER_REPLY_SUCCESS, data=0x0, args=0x6361d0) at client-authenticate.c:277 > #9 0x000000000040eb13 in auth_client_input_ok (conn=0x75b6c8, args=<value optimized out>) at auth-server-request.c:196 > #10 0x000000000040dbf3 in auth_client_input (conn=0x75b6c8) at auth-server-connection.c:136 > #11 0x0000000000414aa8 in io_loop_handler_run (ioloop=<value optimized out>) at ioloop-epoll.c:208 > #12 0x0000000000413b9d in io_loop_run (ioloop=0x6552b0) at ioloop.c:335 > #13 0x0000000000408e81 in main (argc=2, argv=0x7fff57100c58, envp=0x7fff57100c70) at main.c:494 Up until this afternoon we had "login_process_per_connection = yes", and login_max_connections at the default (256). This evening I tried with "login_process_per_connection = no" with no problems, except more CPU load and needing to increase login_max_processes_count (and strictly speaking the max fds set with ulimit -n would need to be increased, though I didn't do that as it would have involved killing and restarting the master process - come back Solaris plimit!) Just after midnight, I switched back to "login_process_per_connection = no" and set "login_max_connections = 32" and managed to get core dumps enabled, hence the above! Apart from this problem, the virtual machine has been doing extremely well, so it's not CPU or I/O load related. I'm not sure whether the problem is caused by the switch from Dovecot 1.2.5 to 1.2.8, Solaris to Linux, physical to virtual, or 32-bit to 64-bit! Perhaps we changed too much at once, but it did mean we kept the service going while power was turned off in our main machine room last weekend ...

[Dovecot] expire db(s)?
by ben＠electricembers.net 23 Dec '09

23 Dec '09

with two separate dovecot/backend servers accessing one central mysql server, will it be ok to have them both use the same expires table? Or will that confuse the actual dovecot --exec-mail ext /usr/local/libexec/dovecot/expire-tool.sh cronjob since some of the entries mailboxes won't exist locally? Ben

[Dovecot] qpopper to dovecot migration
by Jernej Porenta 23 Dec '09

23 Dec '09

Heya, We are in the process of migrating from qpopper to dovecot as POP3 server (and IMAP as well) and we hit the UIDL issue with dovecot. Qpopper uses its own algorithm to create UIDL values and if you set it up to write them down in the mbox file as X-UIDL, then dovecot can use them (pop_uidl_reuse = yes). But if you don't use that feature from qpopper, than X-UIDLs are missing and there is no way to create the same UIDL values. So, I was wondering if anyone else hit that issue and maybe knows how to address it (writing an extension or something)? Thanks in advance, regards, Jernej

[Dovecot] Dovecot Deliver CPU usage
by Aravind Divakaran 23 Dec '09

23 Dec '09

Hi All, We have upgraded the dovecot from 1.0 to 1.2.8. After upgradation we have noticed that dovecot deliver process is utilizing a lot of CPU. As a result the mailsystem will stop working. When we limit the no of procs in postfix for dovecot deliver the CPU usage will come down. But we are not facing this problem with the previous version. Below is the log files for dovecot when the error occurs write_full(/home/vmail/dhanbank.co.in/vinukumarvm/temp.server.be3e5a849a909847) failed: No space left on device dovecot: deliver(user(a)example.com): stat(/tmp/Dovecot Delivery Mail) failed: No space left on device But my system has 54gb of free space for root filesystem where tmp residing. Can anyone help me to solve this issue. Rgds, Aravind

Hi all, after inserting another sieve-rule, I get the following backtrace on deliver. The mail gets delivered into the Mailbox, but as deliver does not exit with 0, postfix bounces the mail.

> (...) > } elsif header :contains ["From"] ["@neon.a1a-server.de"] { > fileinto "Server.ADITSystems.neon"; > } else { > include :global "shared.sieve"; > fileinto "Server.Serveradmin"; > } > Dec 23 11:23:37 deliver(serveradmin(a)aditsystems.de): Panic: file > maildir-uidlist.c: line 1242 (maildir_uidlist_records_drop_expunges): > assertion failed: (recs[i]->uid < rec->uid) > Dec 23 11:23:37 deliver(serveradmin(a)aditsystems.de): Error: Raw backtrace: > /usr/lib/dovecot/deliver [0x80e52a1] -> > /usr/lib/dovecot/deliver(default_fatal_handler+0x3a) [0x80e53ca] -> > /usr/lib/dovecot/deliver [0x80e4c79] -> /usr/lib/dovecot/deliver > [0x807e097] -> > /usr/lib/dovecot/deliver(maildir_uidlist_sync_finish+0x29f) > [0x807f10f] -> > /usr/lib/dovecot/deliver(maildir_uidlist_sync_deinit+0xa8) > [0x807f458] -> > /usr/lib/dovecot/deliver(maildir_transaction_save_commit_pre+0x399) > [0x80820c9] -> /usr/lib/dovecot/deliver [0x807bbb2] -> > /usr/lib/dovecot/deliver(index_transaction_commit+0x4e) [0x80a472e] > -> /usr/lib/dovecot/deliver(mailbox_transaction_commit+0x26) > [0x80a9716] -> /usr/lib/dovecot/modules/lda/lib90_sieve_plugin.so > [0xb7d30b84] -> > /usr/lib/dovecot/modules/lda/lib90_sieve_plugin.so(sieve_result_execute+0x244) > [0xb7d2a024] -> > /usr/lib/dovecot/modules/lda/lib90_sieve_plugin.so(sieve_execute+0x87) > [0xb7d37fa7] -> /usr/lib/dovecot/modules/lda/lib90_sieve_plugin.so > [0xb7d1bcde] -> /usr/lib/dovecot/deliver(main+0x1108) [0x8061618] -> > /lib/i686/cmov/libc.so.6(__libc_start_main+0xe5) [0xb7d8a455] -> > /usr/lib/dovecot/deliver [0x805f3c1] Following output of "dovecot -n": > # 1.2.8: /etc/dovecot/dovecot.conf > # OS: Linux 2.6.26-2-686-bigmem i686 Debian 5.0.3 > protocols: imap imaps managesieve pop3 pop3s > listen: [::], * > ssl_cert_file: /etc/dovecot/dovecot.pem > ssl_key_file: /etc/dovecot/dovecot.pem > disable_plaintext_auth: no > 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_executable(managesieve): /usr/lib/dovecot/managesieve-login > login_process_per_connection: no > login_processes_count: 5 > mail_privileged_group: vmail > mail_location: maildir:~/Maildir > mail_executable(default): /usr/lib/dovecot/imap > mail_executable(imap): /usr/lib/dovecot/imap > mail_executable(pop3): /usr/lib/dovecot/pop3 > mail_executable(managesieve): /usr/lib/dovecot/managesieve > mail_plugins(default): autocreate expire quota imap_quota > mail_plugins(imap): autocreate expire quota imap_quota > mail_plugins(pop3): > mail_plugins(managesieve): > 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 > mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve > imap_client_workarounds(default): delay-newmail tb-extra-mailbox-sep > imap_client_workarounds(imap): delay-newmail tb-extra-mailbox-sep > imap_client_workarounds(pop3): > imap_client_workarounds(managesieve): > pop3_save_uidl(default): no > pop3_save_uidl(imap): no > pop3_save_uidl(pop3): yes > pop3_save_uidl(managesieve): no > 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 > pop3_client_workarounds(default): > pop3_client_workarounds(imap): > pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh > pop3_client_workarounds(managesieve): > managesieve_implementation_string(default): dovecot > managesieve_implementation_string(imap): dovecot > managesieve_implementation_string(pop3): dovecot > managesieve_implementation_string(managesieve): Cyrus timsieved v2.2.13 > namespace: > type: private > separator: . > prefix: INBOX. > inbox: yes > list: yes > subscriptions: yes > namespace: > type: public > separator: . > prefix: Server. > location: maildir:/var/mail/vmail/%d/shared/Server:INDEX=~/indexes/Server > list: yes > subscriptions: yes > lda: > postmaster_address: postmaster(a)terra.a1a-server.de > mail_plugins: quota sieve autocreate > deliver_log_format: %m:%$:%f:%s > log_path: /var/log/dovecot-deliver.log > info_log_path: /var/log/dovecot-deliver.log > auth default: > mechanisms: plain login > passdb: > driver: sql > args: /etc/dovecot/dovecot-sql.conf > passdb: > driver: sql > args: /etc/dovecot/dovecot-sql-master.conf > userdb: > driver: sql > args: /etc/dovecot/dovecot-sql.conf > socket: > type: listen > client: > path: /var/spool/postfix/private/auth > mode: 432 > user: postfix > group: postfix > master: > path: /var/run/dovecot/auth-master > mode: 438 > plugin: > sieve: ~/.dovecot.sieve > sieve_global_dir: /etc/dovecot/sieve/ > sieve_dir: %h/sieve > autocreate: INBOX.Trash > autocreate2: INBOX.Spam > autocreate3: INBOX.Sent > autosubscribe: INBOX.Trash > autosubscribe2: INBOX.Spam > autosubscribe3: INBOX.Sent Best regards & merry christmas!

[Dovecot] Openbsd Postfix-Dovecot-SASL
by thekat 22 Dec '09

Greetings all, I have a OpenBSD /Dovecot server at home running and sending / receiving email "internally" without issue.. Recently, I set up the same at our Parish, but one of our users wants to get their email externally. The user can read their email but has to "send" via the local ISP server.. The problem After much searching I have not found an answer to my question. I would like the user to authenticate to be able to "send" email "through" the server.. OpenBSD uses bsdauth by default in Dovecot. After reading the Postfix http://www.postfix.org/SASL_README.html and the Dovecot Wiki http://wiki.dovecot.org/HowTo/PostfixAndDovecotSASL I have tried multiple configurations but I can't seem to get this to work.. It may be something very simple that I am missing.. All users on the Server have accounts in /etc/passwd (just no shell) Postfix - main.cf mailbox_command = /usr/local/libexec/dovecot/deliver mynetworks = 127.0.0.0/8 smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth smtpd_sasl_auth_enable = yes smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination dovecot --version 1.1.16 dovecot -n # OS: OpenBSD 4.6 i386 base_dir: /var/dovecot/ protocols: imaps listen: *, [::] ssl_cert_file: /etc/ssl/dovecotcert.pem disable_plaintext_auth: no login_dir: /var/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login login_user: _dovecot login_max_processes_count: 256 max_mail_processes: 32 mail_location: maildir:~/Maildir mbox_write_locks: fcntl imap_client_workarounds: delay-newmail netscape-eoh tb-extra-mailbox-sep auth default: cache_size: 1024 passdb: driver: bsdauth args: cache_key=%u userdb: driver: passwd socket: type: listen client: path: /var/run/auth-client mode: 432 user: _postfix master: path: /var/run/auth-master mode: 384 user: _postfix Error using bsdauth Dec 21 15:07:09 aml000t3 dovecot: dovecot v1.1.16 starting up Dec 21 15:07:09 aml000t3 dovecot: Panic: auth(default): file passdb.c: line 190 (passdb_init): assertion failed: (passdb->passdb->default_pass_scheme != NULL || passdb->passdb->cache_key == NULL) Dec 21 15:07:09 aml000t3 dovecot: child 18954 (auth) killed with signal 6 (core not dumped) Dec 21 15:07:09 aml000t3 dovecot: Fatal: Auth process died too early - shutting down It looks like bsdauth has a bug and even though this thread "lists" a patch, I haven't been able to find it.. http://old.nabble.com/bsdauth-with-cache_key-failed-ts25800484.html#a258004… so I guess I am looking for an alternative to be able to allow users to "send through the server" Thx for any pointers tk -- View this message in context: http://old.nabble.com/Openbsd-Postfix-Dovecot-SASL-tp26890148p26890148.html Sent from the Dovecot mailing list archive at Nabble.com.
