[Dovecot] open-folder limit
by T. Horsnell 19 Oct '06

19 Oct '06

Is there a way to limit the number of folders a user can have open simultaneously? I seem to remember a config option which would only permit one imap process per user, and would share this between his folders, but I cant find anything relevant in the docs now. Am I talking nonsense here? I'm new to Dovecot. Cheers, Terry.

[Dovecot] Urgent - Inconsistent Inboxes
by Jakob Curdes 19 Oct '06

19 Oct '06

Hi, An urgent problem that I have : runninng dc 0.99.14 w mbox on local ext3 , nothing special, no nfs, nothing. For this machine we have a backup server rsyncing everything over. Now the main server went down and we started DC on the backup machine some day ago. Everything went well, besides one problem : people complained about missing mails that they had seen beforehand. When looking in the inbox, they were all there. After recreating the imap account (outlook express) or deleting the cache file (thunderbird .msf files) everything was well. But you can't really recreate all accounts after switching to the backup machine every time.... today we went back to the main server and in advance I deleted all .imap.index files hoping that they might have been the eventual cause of the problem, but no, same thing happens again. It now seems to me that this is a pure client issue, but nevertheless two questions : a) who knows a way to tell the client (OE or TB in this case) to disregard all local information and get everything fresh from the server ? b) Can this behavior be influenced from the server side? I know I'm behind with 0.99.14 but up to now there was no problem and "never change a running system". If upgrading could help, I would do it immediately. Any hints welcome, especially fast ones as tomorrow morning I have to get the clients running. Yours, Jakob Curdes

[Dovecot] Assertion failure with Dovecot 1.0rc10

Hi, I am seeing the following (with Dovecot 1.0 rc10): Oct 18 07:35:58 dovecot: IMAP(user): UIDs broken with partial sync in mbox file /var/mail/user Oct 18 07:35:58 dovecot: IMAP(user): mbox sync: UID inserted in the middle of mailbox /var/mail/user (15314 > 9604, seq=5, idx_msgs=224) Oct 18 07:35:59 dovecot: IMAP(user): file mbox-sync-rewrite.c: line 405 (mbox_sync_read_and_move): assertion failed: (need_space == (uoff_t)-mails[idx].space) Oct 18 07:37:42 dovecot: IMAP(user): mbox sync: UID inserted in the middle of mailbox /var/mail/user (15314 > 9604, seq=5, idx_msgs=224) Any idea of what this could be?

[Dovecot] LDAP Username Change
by Todd Johnson 19 Oct '06

19 Oct '06

I have a virtual setup using LDAP where the a user has an email address at 2 domain names. The want the mail kept separate but want to use the same password. I use the mail attribute and insert both email addresses. This works perfectly with deliver but opens the wrong Inbox when I IMAP. Is there a way to disable this in the conf file? host dovecot: auth(default): auth(jeff@idom.net,::ffff:127.0.0.1): username changed jeff(a)idom.net -> jeff(a)jdom.net

[Dovecot] Logging authentication failures?
by dri 19 Oct '06

19 Oct '06

I use a script that watches log files looking for failed ssh login attempts and adds firewall rules when there are enough login failures within a certain amount of time. I would like to apply this to Dovecot to automatically firewall attackers trying to brute-force an IMAP account. Is there a way to make Dovecot log authentication failures (I'm running 1.0.rc10)? In other words, can I configure Dovecot to put something in the log the instant "NO Authentication failed" is sent to the IMAP user? With "auth_verbose = yes" I can see individual authentication mechanisms fail, but I have multiple passdb sections so a failure in one mechanism doesn't mean a complete login failure. Thus, configuring the script to watch for individual mechanism failures may result in the firewalling of legitimate users. Thanks for any info!

[Dovecot] Proxy not working using passwd-file
by Clayton Epp 18 Oct '06

18 Oct '06

I've been having problems setting up my proxy using dovecot. I'm using the passwd-file for authentication as well as the regular unix passwd file. Can someone provide me with a complete example of how this should be done, I'm finding that the documentation on http://wiki.dovecot.org/AuthSpecials is sparse on the details. Please do not assume anything as I am new to both Dovecot as well as Linux (FC5).

[Dovecot] Dovecot-compatible web-based sieve configurator
by Koen Vermeer 18 Oct '06

18 Oct '06

Hi, I've set up dovecot with postfix and I'm using the dovecot LDA. It seems that sieve works, but I'm not that good at writing sieve scripts and I'd like to install something more user-friendly anyway. So: Does anyone know of a web-based sieve configurator that works with the dovecot implementation? I haven't been able to find one yet... Koen

[Dovecot] trash plugin causes crashes in quota plugin?
by Mike Horwath 18 Oct '06

18 Oct '06

I just lost my scrollback - so I'll have to recreate it the issue. Using both 1.0r7 and 1.0r10 on FreeBSD 6.1-STABLE. For the: mail_plugins = quota imap_quota that works fine (using maildir for quota plugin) But... mail_plugins = quota imap_quota trash will cause the quota plugin to die at line 156 of quota.c: root->v.deinit(root); I haven't dug through the code enough to find the actual area for this piece of code to add some debugging. Once I can generate a new traceback, I'll drop another email. -- Mike Horwath drechsau(a)iphouse.net ipHouse - Welcome home!

[Dovecot] passdb checkpassword and lastauth
by Max A 18 Oct '06

18 Oct '06

Hi. If checkpassword interface is used for working with vpopmail, function vpopmail "Record time and ip of last auth attempt" (--enable-auth-logging option for configure) won't work - the file "lastauth" is created in Maildir, but does not contain ip-address. If I had correctly understood, dovecot woldn't have set a enviroment variable TCPREMOTEIP for vchkpw. If changes are made in auth/passdb-checkpassword.c (a patch in attachment), everything will work. Probably, the patch is incorrect and does not solve all problems, however the request is to pay attention to existence of the problem. Also it is possible, that a similar problem exists with other variables TCP UCSPI protocol (http://cr.yp.to/proto/ucspi-tcp.txt) P.S. If use the interface vpopmail instead of checkpassword, the file "lastauth" will not be created at all, that is a little bit inconvenient. ********************************** System: dovecot-1.0.rc10 vpopmail-5.4.17 ASP Linux Server II (RHEL3 clone) kernel 2.4.21-47.EL.aspsmp CPU architecture: x86 (IBM xSeries 336) Filesystem: ext3 ********************************** dovecot configuration: base_dir = /var/run/dovecot/ protocols = imap pop3 disable_plaintext_auth = no ssl_disable = yes login_greeting = Ready. first_valid_uid = 89 last_valid_uid = 89 first_valid_gid = 89 last_valid_gid = 89 protocol imap { listen = 81.26.136.8:144 mail_executable = /usr/local/libexec/dovecot/imap mail_plugins = quota imap_quota mail_plugin_dir = /usr/local/lib/dovecot/imap imap_client_workarounds = delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep } protocol pop3 { listen = 81.26.136.8:112 login_executable = /usr/local/libexec/dovecot/pop3-login mail_executable = /usr/local/libexec/dovecot/pop3 pop3_uidl_format = %f mail_plugins = quota mail_plugin_dir = /usr/local/lib/dovecot/pop3 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } auth default { mechanisms = plain login passdb checkpassword { args = /var/qmail/vpopmail/bin/vchkpw } userdb prefetch { } user = root } dict { } plugin { quota = maildir } *************************************** dovecot configure options: ./configure \ --disable-ipv6 \ --prefix=/usr/local \ --sysconfdir=/etc/dovecot \ --without-passwd \ --without-passwd-file \ --without-shadow \ --without-pam \ --without-bsdauth \ --with-checkpassword \ --with-vpopmail \ --without-static-userdb \ --with-prefetch-userdb \ --without-sql \ --without-pgsql \ --without-mysql \ --without-sqlite \ --with-ssl=openssl \ --with-pop3d \ --without-deliver \ --with-storages=maildir \ --with-docs ***************************************** vpopmail configure options: ./configure \ --enable-auth-module=cdb \ --enable-logging=p \ --enable-md5-passwords \ --enable-make-seekable \ --enable-file-sync \ --enable-ip-alias-domains \ --enable-clear-passwd \ --disable-roaming-users \ --disable-learn-passwords \ --disable-passwd \ --enable-auth-logging diff -ur dovecot-1.0.rc10.orig/src/auth/passdb-checkpassword.c dovecot-1.0.rc10/src/auth/passdb-checkpassword.c --- dovecot-1.0.rc10.orig/src/auth/passdb-checkpassword.c 2006-08-22 06:37:56.000000000 +0400 +++ dovecot-1.0.rc10/src/auth/passdb-checkpassword.c 2006-10-17 16:47:09.000000000 +0400 @@ -226,6 +226,10 @@ env_put(t_strconcat("REMOTE_IP=", net_ip2addr(&request->remote_ip), NULL)); + env_put(t_strconcat("TCPREMOTEIP=", + net_ip2addr(&request->remote_ip), + NULL)); + } if (request->master_user != NULL) { env_put(t_strconcat("MASTER_USER=",

[Dovecot] 1.0.rc10 released
by Timo Sirainen 18 Oct '06

18 Oct '06

http://dovecot.org/releases/dovecot-1.0.rc10.tar.gz http://dovecot.org/releases/dovecot-1.0.rc10.tar.gz.sig I've finally read all the mails in the mailing list and in my INBOX. If I haven't replied to some of your mail, please resend it. Remember that since 1.0.rc9 release dovecot.index.cache files will get rebuilt in 64bit systems, and it's probably better to delete them manually so you don't get errors in log files. There are only a couple of issues left in my v1.0-TODO list: - Master process appears to be leaking log fds with kqueue. Could someone again give me access to a system where this happens? - Login process problems. How well does it work now? Hopefully well enough that v1.0 could be released. - LDAP authentication is leaking memory? Can anyone confirm this? Even better, can someone figure out what exactly is leaking? :) Not a v1.0 blocker though. I think v1.0 will be released once no-one has reported any major problems for a Dovecot release in 2-4 weeks. I think login process handling is the only potentially major problem left. There are a few patches from people that I haven't forgotten, but I've decided not to put them into v1.0 anymore: - Filesystem quota group. I don't think it's that important feature, and it might break something. - HFS+ hardlink avoiding - Managesieve - vmailmgr support And finally the changes in this release: * When matching allowed_nets IPs, convert IPv6-mapped-IPv4 addresses to actual IPv4 addresses first. + IMAP: Try to avoid sending duplicate/useless message flag updates + Added support for non-plaintext authentication for vpopmail if it returns plaintext passwords. Based on patch by Remi Gacogne. + Added %D modified to return "sub.domain.org" as "sub,dc=domain,dc=org" (for LDAP queries). Patch by Andrey Panin. - rc9 broke cache files in 64bit systems - deliver works now with mail_chroot - auth cache didn't work properly with multiple passdbs - Fixes to handling CRLF linefeeds in mboxes.

[Dovecot] autoconf check for ldap not linking with -lber

[Dovecot] Strange POP3 problem...
by Mike Cisar 18 Oct '06

18 Oct '06

I've been having this problem for a long time now. It started when I first began to use Dovecot (0.9x) and seems to have been occurring more and more frequently as we've progressed through the betas and now into RC7. I have been kind of chaulking it up to a "user issue" since the problem only seems to occur for one user (who has one machine at his office, and one at his weekend cabin... problem occurs with equal frequency on both of his machines). Lately it's been occurring about once every couple of days, but still nothing that I have been able to reproduce with any particular email or frequency. However as luck would have it the problem occurred today while I was onsite at the client's office so I was at least able to see that end of things at the same time. Essentially the user will have a number of messages in their mailbox (today for example 13) the download of mail will go just fine until one particular message and then the download will just stop, eventually returning an error message. Trying to receive mail again will retrieve messages 1-9 again and fail in the same spot. If you log in via IMAP and delete the following message (ie. the message after the one that was last received) you can then POP for mail again and the remaining messages in the mailbox will download. In the log all we see is the following (over and over)... Aug 28 16:14:51 mail dovecot: pop3-login: Login: user=<xxxxx>, method=PLAIN, rip=vvv.www.xxx.yyy, lip=vvv.www.xxx.yyy Aug 28 16:15:32 mail dovecot: POP3(xxxxx): Disconnected top=0/0, retr=9/170375, del=0/13, size=1349520 >From the client side I get the following in Outlook Express... "Your server has unexpectedly terminated the connection..." "...POP3, Server Response: '+OK 795 octets'..." Interestingly 795 bytes is the size of the "bad" email (the one that won't download). Any thoughts? Cheers, >>>>> Mike <<<<<

[Dovecot] Index files
by Steven F Siirila 17 Oct '06

17 Oct '06

I am doing some testing with Dovecot and wondered if it was normal for the deliver program to create index files for an Inbox (the test Inbox is over 7MB), but to not update the index files after the initial creation, even though messages continue to come into the mailbox. Note that during this testing, no IMAP or POP accesses are being made. Would it matter if a command-line program such as mutt were reading/updating the Inbox in question? Shouldn't Dovecot delivery be continually updating the index files as new messages arrive in the Inbox? -- Steven F.

[Dovecot] dovecot tpop3d UIDL mbox
by antencek＠volja.net 17 Oct '06

17 Oct '06

Hello All! I am new to this list so I hope I'm not in the wrong list with my question. First, I have to say that dovecot is (in my opinion) one of the best POP3/IMAP servers arround. I especialy like its' simplicity (configuration) and powerfullness (speed, auth mechs). In my production environment I would like to cange from tpop3d to dovecot, but I have only one little problem :). This is my situation: pop3 server: tpop3d mail fromat: mbox (/var/mail/username) UIDL: tpop3d UIDL format Since there are users who let mail on server, I need to keep UIDL. The problem is that the patch which gives dovecot the capability to replay with tpop3d UIDL format apparently works only on maildir mailboxes. Is there any resonable solution to my problem? TIA. Regards, Antencek

[Dovecot] allow_nets and mysql question

Hi. I want to use allow_nets in my configuration, but i have some troubles which i cant resolve. To use allow_nets i creates `allow_nets` text field in my mysql users table. My query is: from: dovecot/sql.conf: password_query = SELECT crypt as password, maildir as userdb_mail, 6 AS userdb_uid,6 AS userdb_gid, allow_nets FROM users WHERE id = '%u' from dovecot.conf: auth default { mechanisms = plain passdb sql { args = /usr/local/etc/dovecot/sql.conf } userdb prefetch { } user = root } To check this i added address 193.193.193.100/32 (which is not my address) and tried to connect from localhost (using telnet).

The alarming aspect of the corruption is when it occurs at the beginning of an email (i.e. ^@^@^@From:...). Emails can be lost/appended to the bottom of the previous email. I've seen this problem several times on our deployment and tracked it down to what appears to be NFS locking issues. Are you storing mails on an NFS mounted filesystem? If so check the following... http://wiki.dovecot.org/NFS We're running dovecot-1.0 beta5 (admittedly not an rc version but >beta4 which is mentioned in the NFS wiki section) so I'm not sure the mbox rewrite from v0.99.x has fixed the problem. We had several applications accessing the mbox (Dovecot and Pine mainly). Reconfiguring Pine to use IMAP (using Dovecot) rather than write to the mbox directly appears to have fixed the problem and we have had no corruption for several months now. So, my question is am I wrong to assume NFS locking/corruption? Does anyone know if this is really a Dovecot or NFS issue? Phil

[Dovecot] 1.0.rc9 released
by Timo Sirainen 17 Oct '06

17 Oct '06

http://dovecot.org/releases/dovecot-1.0.rc9.tar.gz http://dovecot.org/releases/dovecot-1.0.rc9.tar.gz.sig Most importantly this should fix the login process problems that people have been reporting. There were also some bugs in the proxying feature. Also note the 64bit change in dovecot.index.cache files. Unless you delete dovecot.index.cache files manually, you'll these kind of error messages into your logs: Error: Corrupted index cache file ...dovecot.index.cache: registered field date.sent size changed They'll get fixed automatically of course, but it might be a bit annoying to see them. * 64bit systems: dovecot.index.cache file will be rebuilt because some time fields have been changed from 64bit fields to 32bit fields. Now the same cache file can be used in both 32bit and 64bit systems without it being rebuilt. * Added libmysqlclient workaround to conflicting sha1_result symbol, which caused Dovecot to fail logging into MySQL. + dovecot.index.cache file opening is delayed until it's actually needed. This reduces disk accesses a bit with eg. STATUS commands. + auth_cache: Try to handle changing passwords automatically: If password verification fails, but the last one had succeeded, don't use the cache. This works only with plaintext auth. - dovecot.index.cache: We didn't properly detect if some fields were different length than we expected, which caused assert crashes - Lots of fixes to login/master process handling - mbox: Fixed a bug causing "X-IMAPbase uid-last unexpectedly lost in mbox file" errors, and possibly others.

[Dovecot] Separate auth for pop and imap
by Hr. Daniel Mikkelsen 17 Oct '06

17 Oct '06

Hi. Is it possible to set up separate authentication backends for POP and IMAP for a single Dovecot instance? Or does this require two separate dovecot instances with separate config files? Specifically, I want to have one database query for IMAP and one for POP so that I can let these be separate features that I can flag in a database. -- Daniel Mikkelsen Copyleft Software AS

[Dovecot] MBox path
by Rick 17 Oct '06

17 Oct '06

Hi, I'm having great difficulty pointing Dovecot to my MBox files. They are all in /var/spool/mail/username as textfiles.. not directories. So my guess was: default_mail_env = /var/spool/mail/%u Since %u is user. If the user is "server" I would expect it to go to /var/spool/mail/server exactly what I want. But it doesn't /var/spool/mail///home/server. If I create the directory home in /var/spool/mail and make a symlink of the username pointing to /var/spool/mail it does work. But that's a very dirty workaround I rather not use, also because we have a lot of users.. a lot of symlinks. If I set default_mail_env = /var/spool/mail, it also searches for /var/spool/mail///home/server. I feel like I've tried everything. What am I doing wrong? I'm using version 1.0.beta8, included in Fedora Core 5. Thanks, Rick
