[Dovecot] dovecot-1.2-sieve-0.1.3 compile error
by El Bundy 08 Jan '10

08 Jan '10

Hi, when I try to compile dovecot-1.2-sieve-0.1.3 on my NAS I get the error below and I have no idea why and who to fix this. I have a Qnap TS239pro NAS with a Intel Atom CPU running Linux. I installed and configured the ipkg dovecot packet (1.2.beta1). Getting mails via fetchmail and send them with deliver to the IMAP. Not I want to include sieve to filter mails as this is not part of the packet I need to compile this by my own. I installed all needed packets and download dovecot-1.2.beta1 and dovecot-1.2-sieve-0.1.3. I do configure and make for dovecot and ./configure --with-dovecot=../dovecot-1.2.beta1 and make for dovecot-1.2-sieve-0.1.3. All run without any problem till the error below. Any idea how to fix this is welcome. /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 -Wstrict-aliasing=2 -o libsieve.la rfc2822.lo sieve-limits.lo sieve-message.lo sieve-lexer.lo sieve-script.lo sieve-ast.lo sieve-binary.lo sieve-parser.lo sieve-address.lo sieve-validator.lo sieve-generator.lo sieve-interpreter.lo sieve-code-dumper.lo sieve-binary-dumper.lo sieve-result.lo sieve-error.lo sieve-objects.lo sieve-comparators.lo sieve-match-types.lo sieve-address-parts.lo sieve-match.lo sieve-commands.lo sieve-code.lo sieve-actions.lo sieve-extensions.lo cmp-i-octet.lo cmp-i-ascii-casemap.lo mcht-is.lo mcht-contains.lo mcht-matches.lo tst-truefalse.lo tst-not.lo tst-anyof.lo tst-allof.lo tst-address.lo tst-header.lo tst-exists.lo tst-size.lo cmd-require.lo cmd-stop.lo cmd-if.lo cmd-keep.lo cmd-redirect.lo cmd-discard.lo ext-fileinto.lo ext-reject.lo ext-envelope.lo ext-encoded-character.lo sieve.lo ./plugins/vacation/libsieve_ext_vacation.la ./plugins/subaddress/libsieve_ext_subaddress.la ./plugins/comparator-i-ascii-numeric/libsieve_ext_comparator-i-ascii-numeric.la ./plugins/relational/libsieve_ext_relational.la ./plugins/regex/libsieve_ext_regex.la ./plugins/copy/libsieve_ext_copy.la ./plugins/imap4flags/libsieve_ext_imap4flags.la ./plugins/include/libsieve_ext_include.la ./plugins/body/libsieve_ext_body.la ./plugins/variables/libsieve_ext_variables.la ./plugins/enotify/libsieve_ext_enotify.la rm -fr .libs/libsieve.lax mkdir .libs/libsieve.lax rm -fr .libs/libsieve.lax/libsieve_ext_vacation.a mkdir .libs/libsieve.lax/libsieve_ext_vacation.a (cd .libs/libsieve.lax/libsieve_ext_vacation.a && ar x /opt/qnap_install/dovecot-1.2-sieve-0.1.3/src/lib-sieve/./plugins/vacation/.libs/libsieve_ext_vacation.a) libtool: link: ERROR: object name conflicts: .libs/libsieve.lax/libsieve_ext_vacation.a//opt/qnap_install/dovecot-1.2-sieve-0.1.3/src/lib-sieve/./plugins/vacation/.libs/libsieve_ext_vacation.a make[4]: *** [libsieve.la] Error 1 make[4]: Leaving directory `/share/MD0_DATA/.qpkg/Optware/qnap_install/dovecot-1.2-sieve-0.1.3/src/lib-sieve' make[3]: *** [all-recursive] Error 1 make[3]: Leaving directory `/share/MD0_DATA/.qpkg/Optware/qnap_install/dovecot-1.2-sieve-0.1.3/src/lib-sieve' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/share/MD0_DATA/.qpkg/Optware/qnap_install/dovecot-1.2-sieve-0.1.3/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/share/MD0_DATA/.qpkg/Optware/qnap_install/dovecot-1.2-sieve-0.1.3' make: *** [all] Error 2 /opt/ is a link to /share/MD0_DATA/.qpkg/Optware/ Bye El -- GRATIS für alle GMX-Mitglieder: Die maxdome Movie-FLAT!

[Dovecot] shared namespace problem
by Patrick Kaiser 08 Jan '10

08 Jan '10

Hi List, I've got a problem, setting up shared namespaces. I am trying to setup a Mailbox (Maildir) which is accessible for some users. (For example mailbox "sales" and only sales representive have access to it) Mailboxes can be found under /var/vmail/<username>, whereas <username> looks like foo.bar or peter.griffin ;) Now, if I connect via telnet, loggin in as foo.bar and run a03 SETACL foobar peter.griffin lwrxk everything seems fine. Under /var/vmail/foo.bar is a acl-file dovecot-acl-list Under /var/vmail/foo.bar/.foobar is a acl-file dovecot-acl The contents looks ok. Also there is a generated file /var/vmail/shared-mailboxes.db. But if i now loggin in as peter.griffin and setup command a03 LIST "" "*" or a03 LIST "" "#shared" I can not find any shared mailbox. Above you can find my actual configuration. I've tried several versions of location: under shared namespace, but without success. Hope someone has a clue and point me into the right direction. Thanks for your help.

[Dovecot] Dovecot Sieve: Vacation Recipient
by Lukas Kolbe 08 Jan '10

08 Jan '10

Hi! I tried to use the sieve vacation plugin, but we're facing a little problem: our user's addresses are <uid>@<domain>, and if they want to use imap and sieve, they can have a forward to <uid>@imap.<domain>. The return-path, and hence the address the vacation message is sent to, is then <uid>@<domain> and not the original sender of the message. Is there any way to circumvent this? Sending a vacation back to oneself doesn't really make sense here :) Oh, and happy new year and thank you all for this great piece of software! -- Lukas

Well, there might be scenarios, when a local user other than root may sniff the connection on localhost, but I think you have no such one. So to encrypt a connection from localhost to localhost is a waste of ressources. In case of Dovecot you'll need one extra file descriptior (and depending on your settings one extra process as well), plus the CPU time to actually do the encryption. > Yeah.

The webmail-frontend _is_ your client in the view of Dovecot. But since the cert is in /etc/ssl/certs, it should work, but if you validate the cert, the webmail may bark, because you access the SSL-cert with the CN "webmail.domain.gr" by another name "localhost". This is a sign of a man-in-the-middle attack, actually. BTW: Do your SSL IMAP/POP clients also use the name "webmail.domain.gr"? Otherwise they will get a warning as well, maybe each time they connect.

[Dovecot] First time Dovecot user, really impressed so far. What is best IMAP enabled webmail package to go with Dovecot?
by Stan Hoeppner 08 Jan '10

08 Jan '10

Greetings everyone, I'm new to the list as of today. I just installed Dovecot a couple of days ago for the first time, Debian Lenny Dovecot v1.0.15-2.3. So far I'm pretty impressed. I'm using mbox format with Dovecot auto-deciding to place mail in user home directories, which is great. It works very well with the Win32 Thunderbird 3 client over a small basic 100FDX switched net. I've got one list mail folder with 10,600 messages and server side body searching that folder via T-Bird is very quick, on the order of 5 seconds. It would probably be quicker if Dovecot threaded the search to use both CPUs, but pegging just the one CPU the search is still very darn quick. And this is on a dual P2-550 class machine with only 384MB RAM and a single 500GB 7200RPM SATA drive. I'd like to install a webmail package on the same host. I used Squirrelmail for this purpose many years ago and I wasn't wholly impressed with the user interface. I'm also not impressed by the fact that I regularly receive spam from compromised Squirrelmail hosts/accounts. I really like the look/feel of the Scalix Web Access AJAX based interface, but I can't/won't use Scalix as it's not supported on Debian, it has more features than I need, and the system requirements are a bit steep. So, what's the best FOSS IMAP enabled web mail front end with a modern look/feel? I'd like to run it on lighttpd, which I'm already using, not apache. Thanks in advance for any advice. My apologies if my first post is a little OT, but I figured there's probably no better place to ask about the best webmail front end for Dovecot than here. -- Stan

Does Dovecot Sieve plug-in support Dovecot 2.0? We have a few servers running Dovecot 2.0 beta1, but the Dovecot Sieve plug-in (version 0.1.4) won't compile against it. Is this on the Sieve TODO list? If so, when do you see it will happen? Thanks Wenjie

[Dovecot] Dovecot not delivering mail.
by Anthony Nedland 08 Jan '10

08 Jan '10

I get no errors when attempting to send or receive. However, my messages aren't showing up in the mailboxes. I am sending between users on the same server. This is my dovecot -n output ------------------------------------------------ # 1.1.11: /etc/dovecot/dovecot.conf Error: Error in configuration file /etc/dovecot/dovecot.conf line 1076: Unknown section type (section changed in /etc/dovecot/dovecot.conf at line 1038) Fatal: Invalid configuration in /etc/dovecot/dovecot.conf ----------------------------------------------- I was under the impression that this would be an irrelevant message, as my actual dovecot configuration file is dovecot-postfix.conf rather than dovecot.conf. The logging shows login/logout and no errors. Thanks.

[Dovecot] auth, partially resolved
by Spyros Tsiolis 07 Jan '10

07 Jan '10

Hello people, After a lot of wading through the dovecot documentation (which btw, is excellent !, everything lies under "dovecot/doc/wiki"), I managed to authenticate a couple of accounts. For starters, I want dovecot to work as an imap/imaps box and nothing else. So , I went ahead and created a "passwd" file with two users. One user being my name (spyros) and plaintext password and the other user "postmaster" with encrypted password ("/etc/dovecot/passwd" shown) : --- spyros@webmail.domain.gr:{PLAIN}plainpassword postmaster@webmail.domain.gr:{SSHA}SSHAPassword --- Now, if I telnet to port 143 with both users, the system comes back with the following : --- [root@webmail dovecot]# telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN] Dovecot ready . login spyros(a)webmail.domain.gr password . OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH] Logged in --- As I said, it allows login on port 143 for both users. So, the same for "postmaster". Now for port 993 : --- [root@webmail dovecot]# openssl s_client -connect webmail.domain.gr:993 [lots of SSL-related certificate information] * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE AUTH=PLAIN] Dovecot ready . login spyros(a)webmail.domain.gr password . OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH] Logged in --- Again, the same for user "postmaster". I don't paste. So, everything is fine. However, I have an issue with the (?!) issued certificate. If I check the dovecot logs I find nothing. If on the other hand, I do the same check on the Horde application, It comes back with the following : --- * Trying protocol imap/notls, Port 143: SUCCESS - INBOX has 0 messages (0 new 0 recent) * Trying protocol imap/ssl, Port 993: ERROR - The server returned the following error message: SECURITY PROBLEM: insecure server advertised AUTH=PLAIN[SERVERBUG] Internal error occurred. Refer to server log for more information.

However, I would like an opinion before I go ahead and bug them with this. Certificate was created with "dovecot/doc/mkcert.sh" and the relevant certificate file (can't recall its name at the moment). Any help would be appreciated. On the other hand, If I went too far with this I apologize and I'll try to find another way to resolve this. Thank you people, s.

Possibly a webmail service and a desktop imap client. It may be that both machines are trying to manipulate the uidlist at the same time, causing who knows that kind of corruption. This could maybe explain some of the coredumps im seeing in 1.2.7? This is on Debian/Lenny, using NFS spool and NFS control/indexes. Timo, you asked in private mail a few days ago if we're sure the filenames are forever unique. Im sure. I double checked it in the source code. The above filenames are timestamp_hostname.pid, and that seems pretty unique right? Regards, Cor

Note this is *not* the same issue as: - maildir: v1.2.7 and v1.2.8 caused assert-crashes in maildir_uidlist_records_drop_expunges() I applied those patches to my 1.2.8 installation before 1.2.9 was released and that immediately fixed the expunge crash, but the array_delete bug is still there. dovecot -n --------------- bash-3.2# /usr/sbin/dovecot -n # 1.2.8: /etc/dovecot.conf # OS: Linux 2.6.18-164.6.1.el5 x86_64 CentOS release 5.4 (Final) listen: * ssl_cert_file: /rci/local/certs/imapd-pop3d.pem ssl_key_file: /rci/local/certs/imapd-pop3d.pem disable_plaintext_auth: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_max_processes_count: 2048 max_mail_processes: 2048 first_valid_uid: 100 mail_location: maildir:~/Maildir:INDEX=/rci/nqu%h/dovecot:CONTROL=/rci/nqu%h/dovecot mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes mail_drop_priv_before_exec: yes mail_executable(default): /rci/local/etc/convert-courier-imap.sh mail_executable(imap): /rci/local/etc/convert-courier-imap.sh mail_executable(pop3): /rci/local/etc/convert-courier-pop.sh mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): UID%u-%v namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes subscriptions: yes auth default: passdb: driver: pam args: dovecot userdb: driver: passwd -- ================================ David Halik System Administrator OIT-CSS Rutgers University dhalik(a)jla.rutgers.edu ================================

That would of course need a dict-ldap backend implemented, but it would be a generic way to solve this, if its API is good enough. > After another day of looking into this, I believe that there are two concerns to be addressed: 1. dovecot implementation: how dovecot/pigeonhole provides access to these external sources in a sane way. I do like the dict interface for this, which could keep LDAP url's (or SQL queries, etc) out of sieve scripts, and into nicely compartementalized configuration files. Being very ldap focussed at my site, I hadn't looked at dict before today. 2. sieve language: an extension which would allow scripts to get information from an external source. I'm asking the draft-ietf-sieve-external-lists authors a few questions about this. The end result would be something like what follows: Dovecot implementation (proposed): ------------------------------------- <dovecot.conf> dict { dict_sieve = ldap:/etc/dovecot/dovecot-sieve-ldap.conf } plugin { # TODO: proxy this dict? sieve_extsrc = dict } </dovecot.conf> then I'm not sure how you specify multiple hosts with the dict-sql format, so I'm using the postfix convention. there's probably a better way for dovecot. <dovecot-sieve-ldap.conf> map { name = responder_mode server_host = ldap://server1.mycorp.com, ldap://server2.mycorp.com search_base = o=mailstuff query_filter = (&(objectclass=mailschema)(uid=%u)) result_attribute = responder_mode result_scope = sub bind = no version = 3 } map { name = responder_text server_host = ldap://server1.mycorp.com, ldap://server2.mycorp.com search_base = o=mailstuff query_filter = (&(objectclass=mailschema)(uid=%u)) result_attribute = responder_text result_scope = sub bind = no version = 3 } map { name = forward_keep server_host = ldap://server1.mycorp.com, ldap://server2.mycorp.com search_base = o=mailstuff query_filter = (&(objectclass=mailschema)(uid=%u)) result_attribute = mailForwardKeep result_scope = sub bind = no version = 3 } map { # in this case we can have many responses name = forward_addresses server_host = ldap://server1.mycorp.com, ldap://server2.mycorp.com search_base = o=mailstuff query_filter = (&(objectclass=mailschema)(uid=%u)) result_attribute = mailForwardAddress result_scope = sub bind = no version = 3 } </dovecot-sieve-ldap.conf> Sieve language: --------------------- then with proposed new functions of the sieve language (all names plucked out of my head 2hrs ago, would have to think about the semantics some more): 1. a “:list” argument that expects a string-list 2. a “:extsrc” argument that expects an <ext-name: string> and returns a string-list 3. a “:extsrc1” argument that expects an <ext-name: string> and returns a string 4. a new test that uses information that is not in the message, say “arbitrary [comparator] string string” (syntax needs work) sample uses in scripts are then: 1. redirect to a mailing list sourced from ldap (or wheverver): # mailForwardAddress attribute can be present >=0 times redirect :list :extsrc “dict:forward_addresses” 2. decide whether to keep or discard forwarded messages (eg: after the above rule) # mailForwardKeep attribute should only be present once, if at all if arbitrary :is :extsrc1 “dict:forward_keep” “TRUE” { keep; } 3. decide vacation action and text based in information in an ldap dir: # mailResponderMode & mailResponderText attrs should only be present once, if at all if arbitrary :is :extsrc1 “dict:responder_mode” “alwaysreply” { vacation :days 1 :extsrc1 “dict:responder_text"; } if arbitrary :is :extsrc1 “dict:responder_mode” “holiday” { vacation :days 30 :extsrc1 “dict:responder_text”; } ... where the "dict:mapname" syntax would be dovecot implementation specific. could also support the URL & TAG-URI schemes as proposed by draft-ietf-sieve-external-lists. This would allow query URLs as a more general case, using whatever's configured in /etc/ldap/ldap.conf (or whatever the platform's ldap client lib uses). Doing this does raise some resource consumption concerns, hence there should probably be a means of restricting external queries to global scripts only (or sieve_before, sieve_after), and a means of providing timeout values, etc. eg: if arbitrary :is :extsrc1 “ldap:///o=myorg?mailForwardKeep” “TRUE” { keep; } I'll keep on thinking about the design, staring intently at the dovecot sources and http://wiki.dovecot.org/Design for another couple days before attempting to write some code to test this. Feedback on the design of both the sieve language extension, & dovecot interface very appreciated. Cheers, -Martin Foster

[Dovecot] Failed IMAP Login Attempts in Logs
by Carlos Williams 06 Jan '10

06 Jan '10

I had a user telling me that they can't login to the Postfix email server via Webmail (RoundCube) and I decided to see if I could locate this issue in the logs and understand if the user was simply using a wrong password credential and or something more serious. More than likely the person is just using a wrong password but in search of this on my logs, I don't understand why Dovecot doesn't log failed login attempts. When I attempted to login with a wrong password, I show the following in my logs: [root@mail log]# cat /var/log/maillog | grep 'Jan 5' | grep -i 'dovecot' | grep -i 'carlos' Jan 5 11:00:13 mail dovecot: imap-login: Disconnected: user=<carlos>, method=PLAIN, rip=::ffff:192.168.0.10, lip=::ffff:192.168.0.10 Is there a log level or something I am not searching for that will allow me to see failed or invalid logins for Dovecot (IMAP)? Thanks!

[Dovecot] Sorting in IMAP list command?
by Ronald Johnson 06 Jan '10

06 Jan '10

Hi All, I'm running Dovecot 1.2.9 and have noticed the IMAP list command does not appear to send a sorted list of folders with list command. For example on our Cyrus server I get a sorted list of folders (with INBOX listed first): 2 list "" "*" * LIST (\Noinferiors) "/" "INBOX" * LIST (\HasNoChildren) "/" "CalProject" * LIST (\HasNoChildren) "/" "Deleted Messages" * LIST (\HasNoChildren) "/" "Drafts" ... while on our Dovecot server I get seemingly random listing: 2 list "" "*" * LIST (\HasNoChildren) "/" "lsf" * LIST (\HasNoChildren) "/" "mrg" * LIST (\HasNoChildren) "/" "studiosysadmins" * LIST (\HasNoChildren) "/" "Deleted Messages" * LIST (\HasNoChildren) "/" "TriTeam" * LIST (\HasNoChildren) "/" "systemupdates" * LIST (\HasNoChildren) "/" "bb" * LIST (\HasNoChildren) "/" "nagios" * LIST (\HasNoChildren) "/" "server" ... Is this intentional, or have I done something wrong? I didn't see any option in the dovecot.conf to set the behavior of the list output. Here is `dovecot -n`: # 1.2.9: /usr/local/etc/dovecot.conf # OS: Linux 2.6.18-164.6.1.el5 x86_64 Red Hat Enterprise Linux Server release 5.4 (Tikanga) nfs protocols: imap imaps managesieve ssl_cert_file: /etc/pki/dovecot/certs/dovecot.pem ssl_key_file: /etc/pki/dovecot/private/dovecot.pem disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(managesieve): /usr/local/libexec/dovecot/managesieve-login mail_access_groups: BOLT mail_location: maildir:/var/dovecot/imap/%u/Maildir mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(managesieve): /usr/local/libexec/dovecot/managesieve mail_plugins(default): acl imap_acl autocreate mail_plugins(imap): acl imap_acl autocreate mail_plugins(managesieve): mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(managesieve): /usr/local/lib/dovecot/managesieve namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: public separator: / prefix: Public/ location: maildir:/var/dovecot/imap/public:CONTROL=/var/dovecot/imap/%u/Maildir/public:INDEX=/var/dovecot/imap/%u/Maildir/public list: yes namespace: type: public separator: / prefix: Boltlogs/ location: maildir:/var/dovecot/imap/boltlogs/Maildir/:CONTROL=/var/dovecot/imap/%u/Maildir/public-boltlogs:INDEX=/var/dovecot/imap/%u/Maildir/public-boltlogs list: yes lda: postmaster_address: postmaster(a)example.com mail_plugins: sieve acl mail_plugin_dir: /usr/local/lib/dovecot/lda/ auth default: passdb: driver: pam userdb: driver: passwd plugin: acl: vfile sieve: /var/dovecot/imap/%u/home/.dovecot.sieve sieve_dir: /var/dovecot/imap/%u/home/sieve home: /var/dovecot/imap/%u/home autocreate: Trash autosubscribe: Trash Cheers, Ron

[Dovecot] Dovecot quota not working
by Bruno Guimarães Sousa 05 Jan '10

05 Jan '10

Hi everyone, I'm trying to make quota to work in dovecot 1.0.rc15 in a Debian machine. Setting the limit to 1GB and starting to fill up the mailbox and nothing stopped me. It just kept growing and nothing happened. Restarted the service and nothing. I had already exceeded the 1 GB limit and nothing happens, the mailbox still goes bigger and bigger... The *"check_quota"* plugin for squirrelmail shows "0.0% of 1.0GB" in my browser. 1GB is exactly what it is defined in dovecot.conf by maildir. Is it necessary to configure something in postfix?
