[Dovecot] 1.0.rc14 released
by Timo Sirainen 19 Nov '06

19 Nov '06

http://dovecot.org/releases/dovecot-1.0.rc14.tar.gz http://dovecot.org/releases/dovecot-1.0.rc14.tar.gz.sig More fixes. "Duplicate header extension keywords" is the only known problem (or if I forgot something, remind me). I'll try to figure out a way to reproduce it easily and then get it fixed. * LDAP: Don't try to use ldap_bind() with empty passwords, since Windows 2003 AD skips password checking with them and just returns success. * verbose_ssl=yes: Don't bother logging "syscall failed: EOF" messages. No-one cares about them. + Dovecot sources should now compile without any warnings with gcc 3.2+ - rc13 crashed if client disconnected while IDLEing - LDAP: auth_bind=yes fixes - %variables: Fixed zero padding handling and documented it. %0.1n shouldn't enable it, and it really shouldn't stay for the next %variable. -sign also shouldn't stay for the next variable. - Don't leak opened .log.2 transaction logs. - Fixed a potential hang in IDLE command (probably really rare). - Fixed potential problems with client disconnecting while master was handling the login. - quota plugin didn't work in Mac OS X

[Dovecot] quota plugin enhancement request
by Michael Tibben 19 Nov '06

19 Nov '06

Hi am having a small issue with the quota plugin In Squirrelmail when a message is deleted, it seems to be copied to the Trash folder *before* it is deleted from the current folder. However if it is a large message being deleted and the mailbox is close to its quota limit, it means dovecot will deny the copy operation as the quota will be exceeded if the message is copied Because of this, I am wondering if it is possible to have an option for the quota plugin to track, but not enforce the quota. This is because I don't require quota enforcement on IMAP, as Postfix will enforce quota on incoming mail anyway. I hope this makes sense... Michael

[Dovecot] Is "Resource temporarily unavailable" an old problem?
by Ricardo Dias Campos 19 Nov '06

19 Nov '06

Hi. I've installed dovecot recently in a Fedora 5 Linux. It seemed to be OK but I begun to get the message "Can't connect to auth server at default: Resource temporarily unavailable". When I get the message, dovecot hangs. The problem is that "temporarily" is not quite true since the only way to get dovecot running again is to restart it. As a matter of fact, I cannot say that it never recovers. What I know is that it is out for a long, long time. Then a new problem arose: the time between hang-ups begun to diminish. Trying to find why I discovered that the number or dovecot-auth processes was too high (last time I got 169 processes, a lot of them <defuncts>). It seems that, if I kill all these processes, it takes more time before it hangs again. I looked up for messages in the Internet and I found a mail exchange between people from this list. The first hint I got was to upgrade dovecot. As I said, I'm using Fedora 5 and the version distributed with it was dovecot-1.0-0.beta2.7.i386. I upgraded it to dovecot-1.0-0.beta8.2.fc5.i386. I couldn't make any direct relantionship between this versions and the ones in dovecot site so I cannot tell what dovecot version I'm using in terms of dovecot site versioning. Any help is welcome. Thanks, Ricardo

[Dovecot] CHANGE REQUEST: Move config files out of main $sysconfdir
by Brian G. Peterson 19 Nov '06

19 Nov '06

Currently, dovecot places it's config files in $sysconfdir In Makefile.am, this is defines as: confdir = $(sysconfdir) It would be far more friendly to an already overloaded /etc/ directory, and easier to locate the files, to follow the now-common convention and place files in $sysconfdir / dovecot / ... on most systems this would mean: /etc/dovecot/ If there is only a dovecot.conf, it doesn't really matter, but when additional config files get added for ldap, sql, sieve, it starts to add up. Some distributions already make this change, but placing this change in the dovecot core would make it unnecessary for downstream packagers to make a change to the core dovecot distribution files.

[Dovecot] updated gentoo ebuild provides dovecot-sieve
by Brian G. Peterson 18 Nov '06

18 Nov '06

I'm hoping that there are some Gentoo users on this list who will chime in on a bug that is near and dear to my heart. We've created an updated Gentoo ebuild that adds a sieve USE flag and builds dovecot-sieve if the use flag is enabled. The gentoo bug is here: https://bugs.gentoo.org/show_bug.cgi?id=141743 and the ebuild is available as an attachment to that bug, or as a patch attachment (in case you're not running rc14, or just prefer the look of a unified diff) Any gentoo users on this list are urged to install from the ebuild/patch on the bug, and *report back* on the bug or this list, so that the Gentoo dev will know that it's safe to add this to portage CVS. Thank You. Regards, - Brian

[Dovecot] Dovecot LDA, LDAP, Postfix and Spawning programs..
by Jorgen Lundman 18 Nov '06

18 Nov '06

Qmail, when using LDAP, a user can specify delvieryProgramPath, or a .qmail file, to launch something like procmail. Qmail correctly setuid() to the uids set for the user in LDAP, as well as set up the common env vars (HOME, USER, MAILDIR). We moved to Postfix but found that it is quite lacking in the features supported when it comes to "virtual" users. No .forward, and if you set up an alternate transport, they are run as "any user but root, nor postfix, nor the virtual-user's uid". And worse, does not even supply the HOME/MAILDIR values to transport delivery plugin. (Forcing it to getpwnam() or similar). I have an option to make my own setuid program to query LDAP (postmap -q would work), setuid() and call, say, procmail. It has been suggested I can use "maildrop" as it can talk to LDAP. However, I picked "Dovecot" as my pop3/imap program due to an irrational dislike of Courier imap. So, if I tried Dovecot-LDA, would it support the user optionally having a ".forward" file, or perhaps the LDAP attribute deliveryProgramPath, or some other way to filter based on subject/body to sort, and/or forward, mail? If it can use LDAP, will it setuid() to the users uid (as set in LDAP, assuming I cook the LDAP conf entries correctly) when delivering(I'd hope so!) and running external filters? I am still running rc10, which works well but flips out regularly. (Previously mentioned 'too many files open' bug, some leaks in locks) I will upgrade when the LDAP changes are deemed stable.

[Dovecot] two assertion failures
by Mikhail Teterin 18 Nov '06

18 Nov '06

Hello! I was able to overcome the earlier-reported problems (of dovecot treating the standard mailboxes in /var/mail/ as directories) by specifying mail_location (continuing to use the 0.99-era dovecot.conf did not work). Then I started seeing assertion-failures like: file istream-raw-mbox.c: line 499 (istream_raw_mbox_get_body_size): assertion failed: (rstream->mail_size != (uoff_t)-1) these disappeared, when I disabled mmap-access (mmap is limited to 1Gb on FreeBSD/i386), although dovecot-0.99 worked... I can now get to my mail again, but every once in a while the following assertion kills the connection: file mail-transaction-log.c: line 273 (mail_transaction_log_close): assertion failed: (log->files == NULL) Please, advise... Thanks! -mi

[Dovecot] Auth checking also the service
by Alex 18 Nov '06

18 Nov '06

Hello everyone. I'm switching to dovecot from courier-imap and after some problems with Apple Mail client, now everything seems to be fine. The only problem that I have not solved yet is to check also the service (pop3, pop3s, imap, imaps) in the authentication phase. In courier-authlib I do this: MYSQL_SELECT_CLAUSE SELECT username, \ password, \ "", \ 1002, \ 1003, \ '/vmail', \ maildir, \ quota, \ name, \ "" \ FROM mailbox \ WHERE username="$(local_part)@$(domain)" \ AND active=1 \ AND $(service)=1 where $(service) can be pop3, pop3s, imap or imaps. Is it possible to do a similar thing in dovecot? Thank you in advance, Alex

[Dovecot] Help needed
by Ricardo Dias Campos 17 Nov '06

17 Nov '06

Hi. Days ago I sent a message to this list asking for help on a problem that seemed to me to be old: dovecot hangs and dovecot-auth posts log messages like: Nov 16 17:04:39 netuno dovecot: imap-login: Can't connect to auth server at default: Resource temporarily unavailable Nov 16 17:04:42 netuno dovecot: pop3-login: Can't connect to auth server at default: Resource temporarily unavailable Unfortunatelly when this happens the only way to recover is to restart dovecot. After I while I begun to clean the dovecot-auth processes (defunct or not) that remain in the process list and the cycle of running/hunging restart from 1 hang a day until it reaches 1 hang each 10 minutes, when I kill dovecot-auth again. I've seen some days ago some messages related to this problem but they were inconclusive, meaning that they didn't point to a solution. Any help is welcome. Thanks. Ricardo

[Dovecot] LDA Question
by Jeff 17 Nov '06

17 Nov '06

I need some advice about replacing maildrop with the Dovecot LDA. I need to replicate a setup that uses postfix+maildrop+spamassassin. We'll be using Dovecot 1rc13. In the current setup, maildrop reads a file called .mailfilter in each user's folder, then call spamassassin according to the user's preferences. The file is simple, and looks like this -- if ( $SIZE > 20971520 ) { EXITCODE=77 echo "Your email was rejected because it exceeded limit of 20 MB" exit } if ( $SIZE < 26144 ) { exception { xfilter "/usr/local/bin/spamc -u user(a)domain.com" } } exception { to "$DEFAULT/Maildir/" } What is the most straightforward way to have 'Deliver' do the same thing, without changing the way that SA gets called? Apologies in advance if this is a boneheaded question. I've been sorting through Sieve documentation and HOWTOs and I see everything but what I need.

[Dovecot] maildirsize update error?
by Maykel Moya 16 Nov '06

16 Nov '06

According to [1], Trash is a reserverd folder name. When moving a message to it, maildirsize should be update with a negative byte count. If I move a message from any folder to Trash, maildirsize gets two lines, one positive and one negative. The problem is that a user can't move messages to Trash while being overquota because the positive entry goes before the negative. I'm using dovecot-1.0rc14.

[Dovecot] 1.0.rc13 released
by Timo Sirainen 15 Nov '06

15 Nov '06

http://dovecot.org/releases/dovecot-1.0.rc13.tar.gz http://dovecot.org/releases/dovecot-1.0.rc13.tar.gz.sig I'll just keep on making new releases now whenever something important is fixed. Hopefully there shouldn't be many left anymore. Most of the bugs fixed in this release were found by stress testing with my imaptest tool (http://dovecot.org/tools/imaptest.c) If you're interested in knowing how perfectly your Dovecot setup works (especially if you're using NFS), you could try the tool yourself also. I still see one crash with mmap_disable=yes, but it's pretty rare. Will see if I get it fixed before v1.0, but it's not that important. + deliver: If we're executing as a normal system user, get the HOME environment from passwd if it's not set. This makes it possible to run deliver from .forward. - Older compilers caused LDAP authentication to crash - Dying LDAP connections weren't handled exactly correctly in rc11, although it seemed to work usually - Fixed crashes and memory leaks with AUTHENTICATE command - Fixed crashes and leaks with IMAP/POP3 proxying - maildir: Changing a mailbox while another process was saving a message there at the same may have caused the changes to not be made into the maildir, which could have caused other problems later..

[Dovecot] 45second delays on log in
by Ben Marsh 14 Nov '06

14 Nov '06

Dear List Members, We have been running Dovecot as an IMAP server for web based access to email for our customers. At the moment, when the server is under load, some users are finding that it takes 45 seconds to log in. I was wondering if any of you guys would have any tips. I would love any information that would help solve or debug this issue. Background information: The server is Debian with kernel 2.4.31. We are running Dovecot 1.0rc6. I have reviewed the change logs and not found any changes pertinent to our situation from rc6 to rc14 (But maybe I am wrong). We have our own auth mechanism. This auth mechanism is the same used across our other products and we haven't had the same delays with the other products. From the information in the various log files the auth mechanism responds almost instantaneously but it still takes a long time for 1 OK Logged in. message to arrive on the screen when using telnet localhost 143 to login. All the mailboxes are stored over NFS. I have taken the step of moving the INDEXES from NFS to a local hard drive using default_mail_env = maildir:%h/mail:INDEX=/spare/%h in the config file. (/spare is a locally attached hard drive). We are using Maildir for our mailboxes so I am told that locking should not be a problem. A mailbox would never be accessed by two machines simultaneously due to the architecture of the system. In order to gain performance increases we also implemented an IMAP proxy between the webmail client and the imap server. This removes delays in all but the first attempt to access webmail. When logging into a user for which login has been verified to take about 45seconds deletion of the large numbers of messages seemed to speed up login for that particular mailbox indicating to me that it was other things that dovecot does after login and before the 1 OK Logged in. message is displayed that takes up all the time. Unfortunately this theory failed when I tried it with other users. I have also analysed the log files. of the 100,000 lines in the log file 49 were messages: Child 12040 (login) returned error 89 54 were messages: imap-login: Master sent reply with unknown tag 18 The actual number at the end of the message changes lots. The frequency of the extended logins would make it extremely unlikely that these messages are the problem. Any help is very much appreciated. Thanks, Ben Marsh

Hi all, Using dovecot's LDA (debian backports package: 1.0rc2), users who have exceeded their quota when receiving messages see the message get bounced. This works fine for us, however, the sender is sent a message as follows: -- Start bounce text ERROR This is the Postfix program at host foo.domain.com I'm sorry to have to inform you that your message could not be be delivered to one or more recipients. It's attached below. For further assistance, please send mail to <postmaster> If you do so, please include this problem report. You can delete your own text from the attached returned message. The Postfix program <user(a)foo.domain.com>: Command died with status 11: "/usr/lib/dovecot/deliver" -- End bounce text Is it not possible to specify something a bit more civil for the sender? a "User is over quota" message works much better here. We're already running a script which notifies users when they approach a certain specified % that they're about to exceed quota, however, hoping they all comply is another thing entirely. Any assistance would be much appreciated. Regards, -- Mustafa A. Hashmi mahashmi(a)gmail.com mh(a)stderr.net

[Dovecot] NTLM authentication from Outlook
by Lars Skovgaard 14 Nov '06

14 Nov '06

Hi all I've enabled ntlm authentication in dovecot, and use dovecot sasl in postfix as well. Authentication with ntlm works well from Mac OS X Mail.app, as well as from Outlook Express, but fails with Outlook. Strangely enough, ntml authentication works in Outlook when using smtp (via postfix), but neither from imap or pop3 (both dovecot). As dovecot sasl handles all authentication against a mysql userdb, this strikes me as very strange. I've instructed my clients with Outlook to fetch mail using a ssl- encrypted connection, and to send using ntlm-authentication. This works, but I would like to have ntlm available as an option to all my clients, without forcing them to change mail-clients. I've turned on auth_verbose, auth_debug and auth_debug_passwords, and compared the passwordstring with the one calculated using dovecotpw, and they match. The only odd thing is that the username is returned from Outlook as an all-caps string, so user(a)domain.tld becomes USER(a)DOMAIN.TLD. I don't know if it matters, but I don't think so, as changing the user-login to an all-caps version doesn't solve the problem. Any hints will be most welcome. /Lars

[Dovecot] MacOS X and quota-plugin
by Lars Skovgaard 13 Nov '06

13 Nov '06

Hi all, I've installed dovecot 1.0 rc12 on a MacOS X client system with only a handful of users – all virtual – and would like to enable quotas. I've tried searching the wiki for information on how to do this, but haven't been able to find anything – which is why I turn to the list in hope there's someone out there who can point me in the right direction. I've compiled dovecot without any other authentication than sql and pam, and have enabled ssl, pop3 and dovecot lda (for use with postfix when I get around to it). The installation went smoothly, and dovecot is working great without quota-support. However, when I enable quota- support, the imap child-process crashes. Here's a few lines from the log, slightly altered to protect user-identities: Nov 8 23:05:09 SD-Server dovecot: imap-login: Login: user=<imapuser>, method=PLAIN, rip=192.168.2.10, lip=192.168.2.2, TLS Nov 8 23:05:09 SD-Server dovecot: child 22662 (imap) killed with signal 11 Nov 8 23:05:09 SD-Server crashdump[22663]: imap crashed Nov 8 23:05:09 SD-Server crashdump[22663]: crash report written to: / Library/Logs/CrashReporter/imap.crash.log Nov 8 23:05:12 SD-Server dovecot: imap-login: Login: user=< imapuser >, method=PLAIN, rip=192.168.2.10, lip=192.168.2.2, TLS Nov 8 23:05:13 SD-Server dovecot: child 22665 (imap) killed with signal 11 Nov 8 23:05:13 SD-Server crashdump[22666]: imap crashed Nov 8 23:05:13 SD-Server crashdump[22666]: crash report written to: / Library/Logs/CrashReporter/imap.crash.log Nov 8 23:05:16 SD-Server dovecot: imap-login: Login: user=< imapuser >, method=PLAIN, rip=192.168.2.10, lip=192.168.2.2, TLS Nov 8 23:05:17 SD-Server dovecot: child 22670 (imap) killed with signal 11 Nov 8 23:05:17 SD-Server crashdump[22671]: imap crashed Nov 8 23:05:17 SD-Server crashdump[22671]: crash report written to: / Library/Logs/CrashReporter/imap.crash.log This is what I have done in dovecot.conf to enable quota: protocol imap { mail_plugins = quota imap_quota mail_plugin_dir = /usr/local/lib/dovecot/imap } plugin { #quota = dict:storage=10240 #quota = dirsize:storage=10240 #quota = maildir:storage=10240 #quota = maildir:storage=10240 mysql:/usr/local/etc/dovecot-sql.conf #quota = fs:storage=10240 #quota = fs } As you might guess from the lines under "plugin", I've tried a lot of different combinations. If I enable ANY of the above lines under plugin, the child-processes die upon login. When all have been commented out, there's no more crashing – until I try to see how much space is available, then it crashes again. I've tried adding an extra "quota" field to my mysql userdb to handle quotas, but with the same result. mysql-query looks like this (as described in the wiki): user_query = SELECT home, uid, gid, 'dirsize:storage=' || quota_kb AS quota FROM users WHERE userid = '%u' As with the settings in dovecot.conf, Ive tried various combinations of dict, dirsize and so on, but without any luck. This is what the entries in my crashdump file looks like: Host Name: SD-Server Date/Time: 2006-11-09 00:06:17.151 +0100 OS Version: 10.4.7 (Build 8J135) Report Version: 4 Command: imap Path: /usr/local/libexec/dovecot/imap Parent: dovecot [8370] Version: ???

[Dovecot] Deliver: command time exceed limit
by Dominique Feyer 12 Nov '06

12 Nov '06

We use Dovecot on a cluster (10'000 domains, 30'000 account) without any problem with pop/imap. We use Dovecot 1.0 RC10 Now we use virtual transport from postfix for mail delivery. We need the Dovecot LDA for sieve support. We test this solution on some domains with success. But if we change the configuration of all our domains, we have a lots of bounce with this error in postfix log: postfix/pipe[24573]: 4F6D7CF11: to=<info(a)XXXX.com>, relay=dovecot, delay=1200, status=bounced (Command time limit exceeded: "/usr/local/dovecot/libexec/dovecot/deliver") If I watch the deliver activity with ps/awk/watch, I see that if deliver duration time exceed some seconds, the deliver process stay in memory but do nothing. Here a strace output of this case: Process 349 attached - interrupt to quit gettimeofday({1161965973, 768478}, {0, 0}) = 0 poll( Strace output nothing before the SIGKILL from postfix (command time exceed 1200 second), the end of the strace: [{fd=5, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=9, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 2, 2147483647) = -1 EINTR (Interrupted system call) +++ killed by SIGKILL +++ I'm not sure is this problem has a relation with our deliver problem.

[Dovecot] Using Substring Width with Mailhome Variables
by Matthew Fisch 12 Nov '06

12 Nov '06

Hello All, I am currently running Dovecot v1.0.rc13 from dovecot-1.0-0_31.rc13.fc5.at.i386.rpm on Linux HOST 2.6.17-1.2157_FC5 #1 Tue Jul 11 22:55:46 EDT 2006 i686 i686 i386 GNU/Linux. I am trying to install Dovecot in a large mail hosting environment and running into troubles. I have specified my mail home in dovecot.conf as follows: default_mail_env = maildir:/mnt/fileserver/maildir/%0.1d/%1.1d/%d/%n I've also tried among other variations: default_mail_env = maildir:/mnt/fileserver/maildir/%0d/%1.1d/%d/%n The expected behavior here, is to resolve this to: /mnt/fileserver/maildir/a/b/abc.com/user However, Dovecot seems to resolve this to: /mnt/raidzone01/maildir/abc.com/bc.com/abc.com/user/ It appears to me using 'width' with a substring does not work as is advertised on http://wiki.dovecot.org/Variables. This page does describe I need to be using 1.0-tests, what is 1.0-tests? I've also tried the default FC5 package: 1.0-0.beta8.2.fc5. Did I misunderstand the syntax? Am I using the wrong version? I won't be able to use dovecot without support for this feature as I am hosting many thousands of domains and know not how else to resolve them all. Thanks for all your time in advance, Matt Matthew Fisch Your-Site.com

[Dovecot] RFC 2822 - message-id
by Tom Allison 10 Nov '06

10 Nov '06

I was porting some email from one imap server location to another and ran into a feature of something. One of them writes message-id as 'Message-Id' and the other writes it as 'Message-ID'. Because of this, all the messages are forever different. All mail is delivered from postfix and will be in the future. But I'm asking which of these syntaxes is correct or if there is a right/wrong way of writing the headers? RFC2822 doesn't come right out and say it, but all the examples therein are "Message-ID". RFC 822 says they are all the same. Both?

Changed the default from envelope to be "MAILER-DAEMON". - INBOX wasn't shown with LSUB command if only prefixed namespaces were used. - passdb ldap: Reconnecting to LDAP server wasn't working with auth binds. - passdb sql: Non-plaintext authentication didn't work - MySQL passdb ignored all non-password checks, such as allow_nets - trash plugin was broken

[Dovecot] Qpopper migration?
by Steve Goodman (lists) 09 Nov '06

09 Nov '06

Hello, As this is my first post to the list, first and foremost I'd like to thank Timo for writing great software; we've successfully moved to Dovecot for over 10,000 users from UW-IMAP and get great performance. On our overloaded staff POP3/IMAP server, we are looking at replacing qpopper+uw-imapd with dovecot, as an interim before moving them to the main Unix mailstore. The system is primarily POP3, with a small number of heavy IMAP users causing the system grief. There are a large number of POP3 users who leave messages on the server. What I want to ensure doesn't happen is that they are forced to download them again. Do I need to add anything specific in the pop3_uidl_format or am I barking up the wrong tree? Kind Regards, Steve

[Dovecot] SSL-read error in logfile
by Egbert Jan van den Bussche 08 Nov '06

08 Nov '06

Now most things seem to work (rc12 on Mandriva 2007.0), I've been looking more thoroughly at the syslog file. I see a 'syscall failed' at the end of a normal timed poll from the client. I wonder what it means. Sorry for the layout, it is messed up by the cut and paste. I have created the selfsigned cert and key in the /etc/ssl/dovecot/[certs,private] directories.

[Dovecot] Quota without dovecot LDA
by Riccardo Bini 08 Nov '06

08 Nov '06

Hi all, I use dovecot with maildir quota plugin + qmail + vpopmail but not dovecot LDA. My dovecot configuration: default_mail_env=maildir:~/Maildir:INDEX=/var/cache/dovecot/indexes/%h/%u:CONTROL=/var/cache/dovecot/control/%h If CONTROL env is set the maildirsize file is stored in /var/cache/dovecot/control/ but I use vpopmail as LDA. It's possible to add a setting in dovecot.conf to specify if dovecot LDA is active?? This is my pseudo-patch: src/plugins/quota/quota-maildir.c static const char *maildirsize_get_path(struct mail_storage *storage) { if (lda_enable) { return t_strconcat(mail_storage_get_mailbox_control_dir(storage, ""), } else { bool is_file; return t_strconcat(mail_storage_get_mailbox_path(storage, "", &is_file), "/"MAILDIRSIZE_FILENAME, NULL); } } dovecot.conf: lda_enable = no Ciao Rick

[Dovecot] How to give system and virtual users their own mail_location?
by Egbert Jan 08 Nov '06

08 Nov '06

Hi all. Now hopefully as a new thread because I still have this question. Apologies to Geert and Timo for my misbehaviour...(repling to the list and changing the subject). I hace Dovecot rc12 working on Mandriva 2007.0 now for system accounts and virtual accounts both imap and imaps can be used. Th problem now is that I cannot use both types of user at the same time. The 'mail_location = ' strings are very different: Real system users have their Maildir in /home/%u/Maildir/ but virtual users have their maildir in /home/virtual/%d/%n/. How can tell dovecot to use the first for /etc/passwd clients and second for mysql authenticated clients? Just adding two private namespaces does not work. That is for ONE user having more mailbox locations, isn't it? Thanks for any hints! Egbert Jan (NL)

I spent most of today adding new content to the Wiki and cleaning up the existing content. The front page is now also reorganized, but there are several links in it to pages which are still missing. Please write them. :)

[Dovecot] L4 probes..
by Jorgen Lundman 08 Nov '06

08 Nov '06

Probably a special case here, but everytime the L4 probes the port, a line as added to the log. This gets a bit noisy. If a random IP connects, I'd want to see it, but maybe it would be nice to have the option to silence the log entry from certain hosts. For now I patch it locally, but without any .conf finesse. For example: Nov 8 10:55:24 corppop01 dovecot: [ID 107833 mail.info] pop3-login: Disconnected: rip=172.16.253.5, lip=172.16.253.128, TLS handshake Nov 8 10:58:00 corppop01 dovecot: [ID 107833 mail.info] pop3-login: Aborted login: rip=172.16.253.5, lip=172.16.253.128 -- Jorgen Lundman | <lundman(a)lundman.net> Unix Administrator | +81 (0)3 -5456-2687 ext 1017 (work) Shibuya-ku, Tokyo | +81 (0)90-5578-8500 (cell) Japan | +81 (0)3 -3375-1767 (home)

[Dovecot] dovecot lda works with maildir++ but does not enforce the quota?
by Antonio Casado Rodríguez 08 Nov '06

08 Nov '06

Hi all, I use Dovecot lda. Is there the possibility that dovecot lda works with maildir++ but does not enforce the quota? I have dovecot 1.0rc12, postfix, RedHat Enterprise Linux ES 4.0 Update 4. IMAP client Thunderbird 1.5.0.7 Only namespace: namespace private { separator = / inbox = yes prefix = location = maildir:~/Maildir/ } Thanks a lot.

[Dovecot] deliver feature request (filter)
by Neal Becker 08 Nov '06

08 Nov '06

I'm using maildrop for delivery, because I want to filter through spamassassin before delivery. Maildrop makes that trivial. It seems deliver can pipe (one way) to a command, but what is needed is to pipe: deliver -> spamd -> deliver which is what the maildrop xfilter does.

[Dovecot] Duplicate header extension keywords
by Rainer Ophoven 07 Nov '06

07 Nov '06

I'm running dovecot supporting imaps and pop3s in a small home-office environment on a Linux-box, kernel 2.4.33, with postfix-2.3.4, amavisd-new and spamassassin. I use Thunderbird as mail-client on Windows XP. ever since upgrading to RC10 I every now and then find these error messages in doveocot.log: Error: IMAP(rainer): Corrupted index file /home/rainer/Maildir/.software.Dovecot/dovecot.index: Duplicate header extension keywords and close by: Error: IMAP(rainer): Fixed index file /home/rainer/Maildir/.software.Dovecot/dovecot.index: first_recent_uid_lowwater 1952 -> 1951 Misconfiguration or where is the problem? -- in diesem Sinne, Rainer
