[Dovecot] Master user
by Emiliano Rago 29 Feb '12

29 Feb '12

Hi, I'd like to have a master user that can read the other users mailboxes. I have only one user who read and write the mail (i.e. I use the static userdb) and I use namespace for public and shared mailboxes. I can authenticate to the server but I am not able to list the mailboxes: > emiliano@dovecot:~$ telnet localhost imap > Trying 127.0.0.1... > Connected to localhost. > Escape character is '^]'. > * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot ready. > 1 login user*master password > 1 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS ACL RIGHTS=texk] Logged in > 5 LIST "" * > * LIST (\Unmarked) "."

I need some help with the dovecot configuration. I want to remove downloaded messages from Mail Server once the messages have been successfully downloaded by pop3-clients, even when the clients have been configured to save copy of messages in the Server. thanks, Julio

[Dovecot] LDA alias resolution problems..
by Nick Warr 28 Feb '12

28 Feb '12

I use postfix + dovecot LDA + mysql virtual users and up til friday, everything was working just fine. Dovecot is 2.0.beta6 (3156315704ef) Like I said, up til friday, when I added a vacation entry into postfix (which I have now removed to see if it was the reason) mails to the alias virusalert (which is aliased to me) went through just fine. Now I get these sort of errors from the LDA: Feb 27 11:54:03 cluster2 postfix/pipe[31267]: 866F0A41173: to=<virusalert(a)mobilia.it>, relay=dovecot, delay=357414, delays=357413/0.79/0/0.05, dsn=4.3.0, status=deferred (temporary failure. Command output: lda: Fatal: Unknown user ) Other aliases work perfectly, the only difference is that these emails are of local origin, (they're messages from Amavisd) I'm not sure why this has started to be a problem. Can anyone give me an idea where I should start looking? Nick

[Dovecot] Mail delivery to subfolders via address extension, and prefered lda method
by Micha Krause 27 Feb '12

27 Feb '12

Hi, I want to deliver mails directly to subfolders, based on address extensions. Example: Emails sent to: micha+test(a)example.com Should be stored into user micha, folder INBOX.test I was able to reproduce this with exim and dovecot-lda: command = /usr/lib/dovecot/dovecot-lda -e -m "INBOX.${substr_1:$local_part_suffix}" But I was wondering if I could do this within dovecot, which would enable me to use LMTP instead of dovecot-lda. Which brings me to my second question: Which method is "better" for dovecot, lda or LMTP? Micha Krause

[Dovecot] Virtual Folders
by jacob＠alltechservices-ia.com 27 Feb '12

27 Feb '12

Hello, I am trying to get virtual folders to work properly, and I can't seem to. I will be as detailed as possible to remove confusion. Thank you in advance. Goal: Essentially, a gmail clone, but one that I can make work on cPanel hosts with roundcube and squirrel mail, etc. By default, cpanel creates user mail dir structure of (maildir++) inbox, drafts, sent, junk, and trash (with no dovecot specific files until first login) I would like to replace all those folders with virtual representations with more capabilities. I would like to achieve the conversation view that gmail has pulled off so well. cPanel, stock, generates the following dovecot -n: (i am still not sure how it negotiates mail_location yet) # 1.2.17: /etc/dovecot.conf # OS: Linux 2.6.18-238.5.1.el5xen x86_64 CentOS release 5.7 (Final) ssl_cert_file: /etc/dovecot/ssl/dovecot.crt ssl_key_file: /etc/dovecot/ssl/dovecot.key ssl_cipher_list: ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login login_process_per_connection: no login_processes_count: 10 login_max_processes_count: 100 login_max_connections: 500 mail_max_userip_connections: 200 maildir_copy_preserve_filename: yes mail_plugins: quota imap_quota namespace: type: private prefix: INBOX. inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)example.com auth default: mechanisms: plain login cache_size: 2048 username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!#$-=?^_{}~./@+% passdb: driver: checkpassword args: /usr/local/cpanel/bin/dovecot-auth userdb: driver: prefetch socket: type: listen client: path: /var/run/dovecot/auth-client mode: 438 plugin: quota: maildir quota_rule: Trash:ignore I started a test box with Debian running the same version of dovecot (1.2.x) and on that system I run into problems every time I make a virtual folder a root folder. I assume it is trying to look up a normal folder instead of the virtual ones and I am confusing it. So I came here because it would be really really neat if I could pull this off. Again, thank you in advance. -cornfeed

[Dovecot] Dovecot 2.1 with custom OpenSSL fails to build
by Andreas M. Kirchwitz 27 Feb '12

27 Feb '12

Hello Dovecot users! There seems to be a new dependency in some modules (eg, lib-storage, libdovecot-lda, libdovecot-ssl) on OpenSSL. In Dovecot 2.0, those modules didn't require OpenSSL, but 2.1 does. For the linking process the path to the OpenSSL library isn't specified properly (SSL_LIBS). Dovecot fails to build if OpenSSL is in a non-standard path. (Haven't checked if SSL_CFLAGS isn't properly used as well.) Example for lib-storage: env SSL_CFLAGS="-I/usr/local/ssl/include" SSL_LIBS="-L/usr/local/ssl/lib -Wl,-R/usr/local/ssl/lib -lcrypto -lssl" ./configure --prefix=/usr/local/${DOVECOTVER} --with-ssl=openssl --with-ssldir=/usr/local/${DOVECOTVER}/etc/dovecot/certs make gcc -DHAVE_CONFIG_H -I. -I../.. -I../../src/lib -I../../src/lib-master -I../../src/lib-settings -I../../src/lib-mail -I../../src/lib-storage -DPKG_RUNDIR=\""/usr/local/Dovecot-2.1.1/var/run/dovecot"\" -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -fno-builtin-strftime -Wstrict-aliasing=2 -I/usr/local/ssl/include -MT master-connection.o -MD -MP -MF .deps/master-connection.Tpo -c -o master-connection.o master-connection.c mv -f .deps/master-connection.Tpo .deps/master-connection.Po /bin/sh ../../libtool --tag=CC --mode=link gcc -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -fno-builtin-strftime -Wstrict-aliasing=2 -I/usr/local/ssl/include -no-undefined -Wl,--as-needed -o indexer-worker indexer-worker.o indexer-worker-settings.o master-connection.o ../../src/lib-storage/libdovecot-storage.la ../../src/lib-dovecot/libdovecot.la -export-dynamic -ldl -lrt libtool: link: gcc -std=gnu99 -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -fno-builtin-strftime -Wstrict-aliasing=2 -I/usr/local/ssl/include -Wl,--as-needed -o .libs/indexer-worker indexer-worker.o indexer-worker-settings.o master-connection.o -Wl,--export-dynamic ../../src/lib-storage/.libs/libdovecot-storage.so ../../src/lib-dovecot/.libs/libdovecot.so -ldl -lrt -Wl,-rpath -Wl,/usr/local/Dovecot-2.1.1/lib/dovecot /usr/bin/ld: warning: libcrypto.so.1.0.0, needed by ../../src/lib-storage/.libs/libdovecot-storage.so, not found (try using -rpath or -rpath-link) /usr/bin/ld: warning: libssl.so.1.0.0, needed by ../../src/lib-storage/.libs/libdovecot-storage.so, not found (try using -rpath or -rpath-link) ../../src/lib-storage/.libs/libdovecot-storage.so: undefined reference to `OBJ_txt2nid' ../../src/lib-storage/.libs/libdovecot-storage.so: undefined reference to `SSL_set_ex_data' [...] # ldd src/lib*/.libs/*.so src/lib-dovecot/.libs/libdovecot.so: linux-gate.so.1 => (0x00979000) libdl.so.2 => /lib/libdl.so.2 (0x00c31000) librt.so.1 => /lib/librt.so.1 (0x009ed000) libc.so.6 => /lib/libc.so.6 (0x0054d000) /lib/ld-linux.so.2 (0x00c12000) libpthread.so.0 => /lib/libpthread.so.0 (0x008f4000) src/lib-lda/.libs/libdovecot-lda.so: linux-gate.so.1 => (0x0096d000) libdovecot-storage.so.0 => /usr/local/src/dovecot-2.1.1/src/lib-storage/.libs/libdovecot-storage.so.0 (0x00ae4000) libdovecot.so.0 => /usr/local/src/dovecot-2.1.1/src/lib-dovecot/.libs/libdovecot.so.0 (0x00110000) librt.so.1 => /lib/librt.so.1 (0x00189000) libc.so.6 => /lib/libc.so.6 (0x00192000) libcrypto.so.1.0.0 => not found libssl.so.1.0.0 => not found libdl.so.2 => /lib/libdl.so.2 (0x0031c000) libpthread.so.0 => /lib/libpthread.so.0 (0x00ebc000) /lib/ld-linux.so.2 (0x003f8000) src/lib-sql/.libs/libdovecot-sql.so: linux-gate.so.1 => (0x00a95000) libdovecot.so.0 => /usr/local/src/dovecot-2.1.1/src/lib-dovecot/.libs/libdovecot.so.0 (0x002b6000) libdl.so.2 => /lib/libdl.so.2 (0x00ab8000) librt.so.1 => /lib/librt.so.1 (0x0072a000) libc.so.6 => /lib/libc.so.6 (0x008f7000) /lib/ld-linux.so.2 (0x00ebd000) libpthread.so.0 => /lib/libpthread.so.0 (0x00619000) src/lib-ssl-iostream/.libs/libdovecot-ssl.so: linux-gate.so.1 => (0x00da6000) libcrypto.so.1.0.0 => not found libssl.so.1.0.0 => not found libdl.so.2 => /lib/libdl.so.2 (0x00df0000) librt.so.1 => /lib/librt.so.1 (0x00112000) libc.so.6 => /lib/libc.so.6 (0x00b5e000) /lib/ld-linux.so.2 (0x00e76000) libpthread.so.0 => /lib/libpthread.so.0 (0x005a6000) src/lib-storage/.libs/libdovecot-storage.so: linux-gate.so.1 => (0x006ed000) libcrypto.so.1.0.0 => not found libssl.so.1.0.0 => not found libdovecot.so.0 => /usr/local/src/dovecot-2.1.1/src/lib-dovecot/.libs/libdovecot.so.0 (0x00c66000) libdl.so.2 => /lib/libdl.so.2 (0x00491000) librt.so.1 => /lib/librt.so.1 (0x00be2000) libc.so.6 => /lib/libc.so.6 (0x00110000) /lib/ld-linux.so.2 (0x0036b000) libpthread.so.0 => /lib/libpthread.so.0 (0x0029a000) Without SSL_CFLAGS and SSL_LIBS but just PKG_CONFIG_PATH, it also won't work.

[Dovecot] Dovecot altmove questions
by Maria Arrea 27 Feb '12

27 Feb '12

Hello We are using Dovecot 2.0.17 with mdbox+zlib and we are evaluating alternative storage. These are the relevant settings mdbox_rotate_interval = 1d mdbox_rotate_size=60m [...] zlib_save_level = 9 # 1..9 zlib_save = gz # or bz2 [...] zlib plugin enabled in dovecot-lda These are my questions: 1º General mdbox question. We are happy usings zlib_save, but we would like to try bzip2 compression. Can we change zlib to bzlib without problems? In other words, can we mix & match gzipped and bzipped messages in the same mdbox file ? 2º With doveadm altmove we can move messages matching a pattern to alternate storage. I have read an older post in this mailing list about passing specific mdbox options to doveadm altmove. Should be a good idea to have a "main" mdbox area with zlib 9 and mdbox_rotate=1d and mdox_rotate_size=60m and an "alternate area" with bzip9, mdbox_rotate=1 week and rotate_size > 60 MB? In the alternate area should only be "old" mail (1 year older). 3º We have separate raids for indexes (raid 1+0) and mdboxes (raid 5). We have almost 3 TB of gzipped mdboxes, and our backup (bacula) is taking almost 16 hours to make a full backup. Our main problem is that indexes are backupd hours before mdboxes, and that bring us some inconsistencies. What is the "right" way of backing up for separate indexes and mdboxes? Thank you for your support. Maria

[Dovecot] IMAP-proxy or not with sogo webmail and dovecot backend
by Jan-Frode Myklebust 27 Feb '12

27 Feb '12

We've been collecting some stats to see what kind of benefits UP/SquirrelMail's IMAP Proxy in for our SOGo webmail users. Dovecot is running in High-performance mode http://wiki2.dovecot.org/LoginProcess with authentication caching http://wiki2.dovecot.org/Authentication/Caching During the weekend two servers (webmail3 and webmail4) has been running with local imapproxy and two servers without (webmail1 and webmail2). Each server has served about 1 million http requests, over 3 days. server avg. response time # requests ---------------------------------------------------- webmail1.example.net 0.370411 1092386 webmail2.example.net 0.374227 1045141 webmail3.example.net 0.378097 1043919 imapproxy webmail4.example.net 0.378593 1028653 imapproxy ONLY requests that took more than 5 seconds to process: server avg. response time # requests ---------------------------------------------------- webmail1.example.net 26.048 1125 webmail2.example.net 26.2997 1080 webmail3.example.net 28.5596 808 imapproxy webmail4.example.net 27.1004 964 imapproxy ONLY requests that took more than 10 seconds to process: server avg. response time # requests ---------------------------------------------------- webmail1.example.net 49.1407 516 webmail2.example.net 53.0139 459 webmail3.example.net 59.7906 333 imapproxy webmail4.example.net 58.167 384 imapproxy The responstimes are not very fast, but they do seem to support the claim that an imapproxy isn't needed for dovecot. -jf

[Dovecot] v2.0.13 problems after kernel patch for CVE-2011-1083 applied on Centos 5

Greetings, This email is both a request for assistance/help and a heads-up. [8irgehuq] CVE-2011-1083: Algorithmic denial of service in epoll. After ksplice automatically installed the above patch on our mail servers, most/all IMAP/POP3 connections began experiencing time-outs trying to connect, or extreme timeouts in the auth procedure. dovecot: imap-login: Disconnected (no auth attempts): rip=a.a.a.a, lip=b.b.b.b, TLS handshaking: Disconnected dovecot: pop3-login: Disconnected (no auth attempts): rip=a.a.a.a, lip=b.b.b.b, TLS handshaking: Disconnected dovecot: pop3-login: Panic: epoll_ctl(add, 6) failed: Invalid argument dovecot: pop3-login: Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0 [0x3cb543baa0] -> /usr/lib64/dovecot/libdovecot.so.0 [0x3cb543baf6] -> /usr/lib64/dovecot/libdovecot.so.0 [0x3cb543afb3] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handle_add+0x118) [0x3cb5447708] -> /usr/lib64/dovecot/libdovecot.so.0(io_add+0xa5) [0x3cb5446e15] -> /usr/lib64/dovecot/libdovecot.so.0(master_service_init_finish+0x1c6) [0x3cb54355a6] -> /usr/lib64/dovecot/libdovecot-login.so.0(main+0x136) [0x37a000bdf6] -> /lib64/libc.so.6(__libc_start_main+0xf4) [0x3cb301d994] -> dovecot/pop3-login(main+0x49) [0x401b99] dovecot: master: Error: service(pop3-login): child 27603 killed with signal 6 (core not dumped - add -D parameter to service pop3-login { executable } dovecot: master: Error: service(pop3-login): command startup failed, throttling dovecot: imap-login: Panic: epoll_ctl(add, 6) failed: Invalid argument dovecot: imap-login: Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0 [0x3cb543baa0] -> /usr/lib64/dovecot/libdovecot.so.0 [0x3cb543baf6] -> /usr/lib64/dovecot/libdovecot.so.0 [0x3cb543afb3] -> /usr/lib64/dovecot/libdovecot.so.0(io_loop_handle_add+0x118) [0x3cb5447708] -> /usr/lib64/dovecot/libdovecot.so.0(io_add+0xa5) [0x3cb5446e15] -> /usr/lib64/dovecot/libdovecot.so.0(master_service_init_finish+0x1c6) [0x3cb54355a6] -> /usr/lib64/dovecot/libdovecot-login.so.0(main+0x136) [0x37a000bdf6] -> /lib64/libc.so.6(__libc_start_main+0xf4) [0x3cb301d994] -> dovecot/imap-login(main+0x39) [0x402069] dovecot: master: Error: service(imap-login): child 27604 killed with signal 6 (core not dumped - add -D parameter to service imap-login { executable } Once this patch was removed, everything started working again. Is it possible that dovecot is trying to re-add already-added connections to the polling list - which this specific 'patch' prevents? We haven't dug deeper yet, but the error is being thrown from the method io_loop_handle_add in ioloop-epoll.c http://hg.dovecot.org/dovecot-2.0/file/aa8dfa085a99/src/lib/ioloop-epoll.c Thanks Doug

[Dovecot] deliver(test@[***domain_name***]): Fatal: setgid(5000) failed with ... Operation not permitted
by fxCode 26 Feb '12

26 Feb '12

Hi, I am relatively new to linux, and have set up my first lamp server around a month ago. The server is housed in a data centre a few miles from my house, and is working as a web server (with apache, tomcat, mysql) just fine. I have now been trying for a week to get Postfix and Dovecot working with postfixadmin and mysql. (below I have replaced my test domain name with [***domain_name***]) The story so far; I can send 'welcome' emails from within postfix admin to an external email address... and they are received by the mail client on my computer at home no problem. I can set up alias email addresses within postfix admin, such as webmaster@[***domain_name***], and emails sent to this address are redirected to the proper address as expected. But - if I set up a standard mailbox within postfix admin - test@[***domain_name***] , and email it from my home system, nothing appear in postfixadmin (after a fetch request) or the mysql database. Here is the fail point in my mail.log file ; Feb 26 12:50:27 quantum dovecot: deliver(test@[***domain_name***]): Fatal: setgid(5000) failed with euid=8(mail), gid=8(mail), egid=8(mail): Operation not permitted I don't know what the setguid(5000) is, or where it is being set, or what it should be! I have been changing permissions with the 'socket listen' section of my /etc/dovecot/dovecot.conf file, and when I restart dovecot it creates the auth-master file with the permissions as expected; socket listen { master { path = /var/run/dovecot/auth-master mode = 0777 user = vmail group = mail } client { path = /var/spool/postfix/private/auth mode = 432 #user = postfix #group = postfix } } my mail folders should be located at /var/vmail, but the folder is empty. I have chmod the permissions to be as follows; me@myserver: ls -ld /var/vmail drwxrwxrwx 2 vmail mail 4096 2012-02-11 08:40 /var/vmail Can anyone spot where this is going wrong? Thanks in advance for any help, it is very very much appreciated!!!

[Dovecot] IMAP NOTIFY extension
by Timo Sirainen 26 Feb '12

26 Feb '12

http://hg.dovecot.org/dovecot-2.2-notify/ contains the initial implementation of IMAP NOTIFY extension. It's less than half-working, but the difficult part of it is done I think. If I give it a command like: x notify set (personal (messagenew messageexpunge flagchange)) and then in another session I copy a message to another mailbox, it sends: * STATUS "foobar" (MESSAGES 77 UIDNEXT 78 UIDVALIDITY 1329431281 UNSEEN 75) This requires mailbox_list_index=yes to work. It works by following the dovecot.list.index.log changes, so it's going to be pretty efficient. Some TODO that I've so far noticed: - NOTIFY is handled currently only for non-selected mailboxes. (handling the new features for selected mailbox should be simple) - initial STATUS sending isn't done with STATUS option - only MessageNew, MessageExpunge and FlagChange notifications are sent currently - MailboxName handling probably needs to be able to get "old" and "new" views, figure out what changed in them and send those changes (dsync has similar code) - mailbox list indexes seem to be adding too much stuff, which results in: - STATUS duplicates, but there should already be code to avoid these so I'm not sure what's going on - ACLs and shared mailboxes don't work right - add 0.5s delay before notifying IMAP code, so multiple changes can be bundled into one

[Dovecot] Maildir migration: Courier-imap 4.4.3 to Dovecot 1.2.
by Rafał Radecki 25 Feb '12

25 Feb '12

Hi all. I am currently gathering information about migration of Maildir/ structures from Courier to Dovecot. What do you think about http://wiki.dovecot.org/Migration/Courier ? For each courier Maildir account I want to use http://www.dovecot.org/tools/courier-dovecot-migrate.pl to produce dovecot-uidlist file mv courierimapsubscribed subscriptions sed sed -i 's/INBOX\.//' subscriptions rm -r courierimaphieracl rm courierimapacl rm courierimapkeywords I want also to leave default pop3_uidl_format (%08Xu%08Xv) in dovecot.conf Should I look into something else? Have I missed something? Best regards, Rafal.

[Dovecot] Apple od/ad authentication problem
by Troy Shafer 25 Feb '12

25 Feb '12

Hello all. Im pretty new to dovecot and postfix world. I'm completely stumped. OS X 10.7.3, behind a Cisco asa NAT. When trying to authenticate (ssl or not) via the webmail interface I get this error... NAT IP is the public ip I assigned. It doesn't work for an AD account or an account local to the Mac server. However it DOES work on the internal LAN. Feb 22 18:15:36 mail dovecot[3501]: auth: Error: od (username,natIP): verify plain: lookup failed for user: username Feb 22 18:15:51 mail dovecot[3501]: auth: Error: od[getpwnam_ext](username,natIP): No record for user I figured I'm missing something in the dovecot config. I have followed apple's kb articles for AD webmail authentication and kerberos, and that works internally.
