[Dovecot] building dovecot-sieve against installed dovecot
by Geert Hendrickx 29 Dec '07

29 Dec '07

Hi Timo, may I request once more to consider the attached patch for dovecot 1.1, it enables the sieve plugin (incl. sievec and sieved, needed for pysieved) to be built against an installed dovecot package, if --enable-header-install additionally installs the liblib.a library in the same directory as dovecot-config. I have included this patch in the pkgsrc dovecot 1.1 package a while ago. Geert

[Dovecot] global and per-users sieve filters
by Nikolay Shopik 29 Dec '07

29 Dec '07

Hi Timo, I'm curious about such thing, currently if user have their own filter global filter no more take a place. Is this behavior changed in 1.1 or maybe in future? I'm unsure if this is 100 sieve related or more like Dovecot handling so fixing can be easily can done.

[Dovecot] v1.0.10 released
by Timo Sirainen 29 Dec '07

29 Dec '07

http://dovecot.org/releases/1.0/dovecot-1.0.10.tar.gz http://dovecot.org/releases/1.0/dovecot-1.0.10.tar.gz.sig v1.0.8 and v1.0.9 were a bit bad releases. Hopefully one day I've managed to have written a proper test suite which can be run before doing any releases.. * Security hole with LDAP+auth cache: If base setting contained %variables they weren't included in auth cache key, which broke caching. This could have caused different users with same passwords to log in as each other. - LDAP: Fixed potential infinite looping when connection to LDAP server was lost and there were queued requests. - mbox: More changes to fix problems caused by v1.0.8 and v1.0.9. - Maildir: Fixed a UIDLIST_IS_LOCKED() assert-crash in some conditions (caused by changes in v1.0.9) - If protocols=none, don't require imap executables to exist

[Dovecot] How to logoff a session with dovecot?
by Robin Atwood 29 Dec '07

29 Dec '07

I use dovecot to push email to my SE P1i and it works very well. :) However, I have two email accounts set up on the phone, one using my domain for GPRS and public WiFi and one using my WLAN address for use at home, the idea being I don't want to pay for GPRS data at home. The trouble is the GPRS account remains logged on and I get the mail in both inboxes. There is no option in the email client on the phone to disconnect, so is there any trick to forcing a disconnect from the mail server?

Hi Timo, great, that fix it! Thx.

[Dovecot] Fishing attempt locking up dovecot
by Patrick Milvich 29 Dec '07

29 Dec '07

I've mentioned this before but only heard from one other person who has experienced this, but it's becoming a pretty serious issue. The situation: A spammer sets a bot on a fishing attempt to gain email addresses, causing numerous login processes to spawn and suck up all available resources. The problem: Obviously this can act like a dos attack, but the real issue is after the spammer stops (by virtue of being added to our firewall blacklist, being caught and shut down by their isp, or otherwise), dovecot doesn't seem to relinquish the resources, causing "too many files open" errors for normal usage. The master process usually hangs around 40-50 files open at any given time, with about 10,000 logins a day (I use: lsof -p `cat /var/run/ dovecot/master.pid ` | wc -l), after the attempt is over I always see the files open shoot up to near 3,000 without it able to go down until a dovecot restart. This usually happens about once a month, though we can get unlucky and have it happen a few days apart. I have some log excerpts below. Wondering if this is happening through my own fault or at least within my ability to alleviate the issue. Is there a way to limit the number of connections from an ip address? Has anyone used login_executable to first hit their own solution to keep track of, and implement connection restrictions similar to what I'm aiming for?

[Dovecot] v1.1.beta11 released
by Timo Sirainen 29 Dec '07

29 Dec '07

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta11.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta11.tar.gz.sig This one should be the last beta release before the first v1.1 release candidate. I'll try to stay away from this list and Dovecot in general for the next 1,5 weeks. I've several exams coming up and I should have started studying for them days ago already.. :) The main things left in my TODO are: - Squat indexes should handle expunges - Lucene indexes are broken - See if \recent flag handling could be fixed for maildir/mbox (it works for dbox though) - Some other minor things which I'll do if I have time, but won't block v1.1.0 release. Changes since beta10: - One major performance issue found and fixed. This was the main reason why we weren't yet in release candidate stage. - configure --with-package now gives an error if it can't find the necessary libs/headers for the package. Use --with-package=auto for the old behavior. - Memory leak fixes - Convert plugin fixes. Conversion is now done to namespace with INBOX. - Changes to handling group adding/removing to processes. Hopefully didn't break anything. - Message flag/keyword searches are now faster - Fixes/optimizations to handling SORT. After building initial indexes, my 260k mail mailbox sorts in about 0.01 seconds. :) - Fixes to searching mails with unknown charsets/invalid data - deliver_log_format setting

[Dovecot] auth-ldap not resetting connection state after failed bind
by Brendan Braybrook 28 Dec '07

28 Dec '07

timo, i think i found a small problem with the ldap implementation: when using auth_bind (this might be in all conditions, not just that one - i haven't tested further), if the server lost connection to the ldap server (ie, the ldap server died) dovecot-auth would never reconnect to the ldap server and all subsequent auth attempts would fail. after a little more digging, i discovered that if the ldap server went down and came back up before the next dovecot request then everything would be fine. however, if a request came in while the ldap server was down then dovecot-auth would "cache" that the server was unavailable and never recheck it. i believe i tracked it down to a couple lines in db_ldap_bind and fixed it - dovecot-auth is reconnecting to ldap in the condition where it was not previously: --- dovecot-1.0.3/src/auth/db-ldap.c 2007-10-15 18:26:55.983349000 +0000 +++ dovecot-1.0.3/src/auth/db-ldap.c.new 2007-10-15 18:28:03.124136000 +0000 @@ -446,7 +446,10 @@ msgid = ldap_bind(conn->ld, conn->set.dn, conn->set.dnpass, LDAP_AUTH_SIMPLE); if (msgid == -1) { - db_ldap_connect_finish(conn, ldap_get_errno(conn)); + if (db_ldap_connect_finish(conn, ldap_get_errno(conn)) < 0) { + /* lost connection, close it */ + ldap_conn_close(conn, TRUE); + } i_free(ldap_request); return -1; }

[Dovecot] dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server
by Rolf E. Sonneveld 28 Dec '07

28 Dec '07

Hi, I'm new to the list; excuse me if this has been asked recently/before. running: # dovecot --version 1.0.8 Output of dovecot -n: base_dir: /var/run/dovecot protocols: none ssl_disable: yes login_dir: /var/run/dovecot/login login_executable: /usr/local/dovecot/libexec/dovecot/imap-login auth default: verbose: yes debug: yes debug_passwords: yes passdb: driver: ldap args: /usr/local/dovecot/etc/dovecot-ldap.conf userdb: driver: ldap args: /usr/local/dovecot/etc/dovecot-ldap.conf socket: type: listen client: path: /usr/local/postfix/spool/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot-auth-master mode: 438 Using dovecot only for the purpose of providing SMTP AUTH service for Postfix, using Active Directory (AD) as authentication source. As you can see from the config, connectivity between Dovecot and AD is implemented using LDAP. Contents of /usr/local/dovecot/etc/dovecot-ldap.conf (some site-specific info masqueraded): auth_bind = yes pass_filter = (sAMAccountName=%u) hosts = AD1.domain.com:3268 AD2.domain.com:3268 dn = CN=Service Account Postfix,OU=Services,DC=domain,DC=com dnpass = secret ldap_version = 3 base = DC=domain,DC=com scope = subtree Now, this works fine and authentication via SMTP AUTH + Dovecot works perfect. Yet, every 15 minutes I get the following warning in the syslog logfile: Dec 24 07:20:00 hostname dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server Dec 24 07:35:01 hostname dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server Dec 24 07:50:01 hostname dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server Dec 24 08:05:02 hostname dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server Dec 24 08:20:02 hostname dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server Dec 24 08:35:03 hostname dovecot: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server I've looked through the archives and it seems that this problem is caused by the fact that Dovecot (using the OpenLDAP client libraries?) keeps the LDAP connection open; after (in our case) 15 minutes Active Directory closes the connection and Dovecot signals this in the syslog (and presumably automatically will create a new connection to AD). I'm pretty sure that the OpenLDAP client libraries provide options to use a client-side timeout for LDAP connections. My questions are: * is there a reason that Dovecot wants to keep the LDAP connection open? * Will the new V1.1 version have a config parameter to set the LDAP client timeout or a default timeout value to close the connection? * If there's no 'fix' foreseen for V1.1, I'd like to file a request to add such a parameter. How can I file such a request? The warning is annoying; the sysadmin will create a filter, to filter the warning out from the syslog, but I'm afraid that if there's a real problem with authentication, that will be filtered too and the real problem is not noticed, before users start to complain. /rolf

But my dovecot -n namespace section shows: namespace: type: private separator: / prefix: INBOX/ inbox: yes list: yes subscriptions: yes According to this I've set separator to "/". And this is the problem. I think problem arised somewhere between beta9 and beta11, as it worked before... The separator in imapsync was for both "/" (--sep1 /, --sep2 /), I just played with all possibilities...

Forwarding all mail to a SMTP server on the machine running dovecot and doing delivery there isn't the favoured option (at least for us). Yes, LMTP would be nice, but it pretty much requires v2.0 framework. I'm still not sure if the next version will be v1.2 or v2.0.. Jetzt Mails schnell in einem Vorschaufenster überfliegen.

Hi, i still try to get dovecot to run under cygwin. After a post on the cygwin list i am able tu run dovecot. Under Cygwin you have to run dovecot by inetd. Starting the binary "dovecot.exe" does not work. Well the server is running but answers with a fatal error. Account: 'localhost', Server: 'localhost', Protokoll: POP3, Serveranswer: 'Fatal: EOF while reading environment from master', Port: 110, Secure (SSL): No, error on server: 0x800CCC90, Fehlernummer: 0x800CCC90 This error is from Outlook, Thunderbird just says there is an error without any error message. So maybe you can help me to bring my story to a hapy end ;-) Cheers Ronny

Here what one of my users sometimes gets in logs when using IMAP: dovecot: IMAP(skribtsov(a)pawlin.mass.hc.ru): Disconnected in IDLE dovecot: IMAP(skribtsov(a)pawlin.mass.hc.ru): Maildir /usr/local/mail/pawlin.mass.hc.ru/skribtsov/Maildir sync: UID inserted in the middle of mailbox (59 > 16, file = 1198267793.H747026P68033.mail5.hc.ru:2,RS) dovecot: IMAP(skribtsov(a)pawlin.mass.hc.ru): Disconnected: Mailbox is in inconsistent state, please relogin. dovecot: IMAP(skribtsov(a)pawlin.mass.hc.ru): Maildir /usr/local/mail/pawlin.mass.hc.ru/skribtsov/Maildir sync: UID inserted in the middle of mailbox (59 > 16, file = 1198267793.H747026P68033.mail5.hc.ru:2,RS) dovecot: IMAP(skribtsov(a)pawlin.mass.hc.ru): Disconnected: Mailbox is in inconsistent state, please relogin. dovecot: IMAP(skribtsov(a)pawlin.mass.hc.ru): Corrupted transaction log file /usr/local/mail/pawlin.mass.hc.ru/skribtsov/Maildir/dovecot.index.log.2: invalid indexid (1198254020 != 1198498301) dovecot: IMAP(skribtsov(a)pawlin.mass.hc.ru): Corrupted index cache file /usr/local/mail/pawlin.mass.hc.ru/skribtsov/Maildir/dovecot.index.cache: indexid changed After that, some messages could "disappear" from messages list.

My problem is the per user quota, if i want give some user, more or minus space, i'm not able to do this. I've added a quota field to the mysql that read dovecot, but i don't know ho to read this in dovecot-mysql.conf. Someone can help me? Thanks

Where can I found the log that dovecot writes if a user fails to log in? I am authenticating agains an sql db, but I can't find where dovecot logs this, if it does?

[Dovecot] v1.1.beta12 released
by Timo Sirainen 25 Dec '07

25 Dec '07

http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta12.tar.gz http://dovecot.org/releases/1.1/beta/dovecot-1.1.beta12.tar.gz.sig Still not a release candidate, maybe the next one.. This release fixes a lot of bugs and adds some new sanity checks. Fixes quite a lot of mbox problems. v1.1.beta11 (no other versions) had a potential security hole where memory was free()d multiple times. \Recent flags should work perfectly now with mbox. Still somewhat broken with maildir.

[Dovecot] Brute Force Blocking?
by Ben Cadieux 24 Dec '07

24 Dec '07

Hi Everyone, Before I begin, I'd just like to mention: I love dovecot. Thank you :) Anyway, today I had 8000 login attempts to my dovecot server in an hour before blocking the IP with my firewall. After googling, I didn't see very much discussion on the topic. There was some mention of blocksshd which was supposed to support dovecot in the next release (but doesn't appear to) and also fail2ban. While a script that parses logfiles will work, I'm not sure that this is the best way to go about handling repeated authentication failure. Would it not be best built into dovecot? Are there any plans for this? Best Regards, Ben Cadieux

[Dovecot] Compact all maildirs with dovecot-1.0.9?
by Jeff Kowalczyk 22 Dec '07

22 Dec '07

I'm running dovecot-1.0.9 on Gentoo Linux. I recently observed a large increase in disk usage on this dedicated mailserver. I attribute it to high spam traffic and/or large attachments for legit email retained on the server. How can I run a command equivalent to an IMAP client's 'Compact Folder' on the entire tree of maildirs under each /home/(user)? Thanks.

yep, originally I want Dovecot to behave exactly the same like our Cyrus environment regarding namespaces, in preparation of a migration :) The first login shows Dovecot output, second show Cyrus, for comparison...
