[Dovecot] Sieve Vacation virtual support?
by Charles Marcus 15 Feb '07

15 Feb '07

Hello, I'm wanting to enable vacation messages for my users on a new dovecot server that I'm playing with, but want to know if the Dovecot LDA+Sieve vacation message function http://wiki.dovecot.org/LDA/Sieve will work with virtual users? For security reasons, I only want to use virtual domains/users. Thanks... -- Best regards, Charles

[Dovecot] selective logging
by T. Horsnell 15 Feb '07

15 Feb '07

>From the wiki: log_path = Use this logfile instead of syslog(). /dev/stderr can be used if you want to use stderr for logging (ONLY /dev/stderr - otherwise it is closed). (I dont understand the above references to the use of stderr) info_log_path = For informational messages, use this logfile instead of the default (What exactly is an informational message, and what is the default?) Can I selectively suppress logging like: Feb 5 11:52:15 ls1 imap(iamelel): File isn't in mbox format: /gfg0/iamelel//claudia/ligplot/NQ10/ligplot.bonds Or do I have to turn off logging entirely?

[Dovecot] maildir and the separator for subfolder
by David Bonnafous 15 Feb '07

15 Feb '07

hi, I use dovecot 1.0rc15 with one maildir namespace. I'd like to be able to use '.' in folders and subfolders name. So, I setup the default namespace with separator =':' But, when I create some folders and then subfolders with thunderbird the filename one the server are named with some '.' no ':'... It seems that dovecot always interprets '.' as a separator for folders. Is-it a bug ? yours, -- David Bonnafous Institut de Mathématiques Université Paul Sabatier Toulouse - France

[Dovecot] deliver LDA permission problem
by Dick Middleton 15 Feb '07

15 Feb '07

Hello, I'm trying to get deliver LDA working with postfix in a virtual domain configuration. I'm using dovecot v1.0.rc10. My setup is pretty much exactly as in the wiki (only the path to deliver and auth-master socket are different). I'm having a little problem with permissions and this occurred which I think is undesirable: syslog: Feb 8 13:09:35 deliver(<email-addr>): setgid(5002) failed: Operation not permitted Feb 8 13:09:36 deliver(<email-addr>): setgid(5001) failed: Operation not permitted mail.log: Feb 8 13:09:36 Devil postfix/pipe[9622]: 5AD5C103C: to=<<email-addr>>, orig_to=<<email-addr>>, relay=dovecot, delay=0.05, delays=0.01/0/0/0.04, dsn=5.3.0, status=bounced (Command died with status 89: \"/usr/libexec/dovecot/deliver\") When deliver fails because it can't connect to auth-master socket it returns an undeliverable status which causes postfix to defer delivery. I think it should do the same here. The real question is how I give deliver the permission to do the setgid? Is it enough to just add user vmail to each of the virtual user groups in /etc/group. Does deliver setuid to virtual user as well? Dick

[Dovecot] dict quota not being updated for all users when receiving a multi-recipient message
by Justin McAleer 15 Feb '07

15 Feb '07

I've set up a mysql quota dictionary using the proxy setup as described in the wiki (using Dovecot lda). When I send a single message to multiple users, only the first recipient is getting their usage updated. This behavior occurs if I manually send to more than one user via the To: line, or via aliases set up in postfix. I do have dovecot_destination_recipient_limit set to 1. I don't even have a guess as to what might be going on here, since each instance of the lda is a separate process. But, let me know if anybody has any ideas or requests for more info.

[Dovecot] sieve plugin
by pod 15 Feb '07

15 Feb '07

I'm currently looking at dovecot for a large-scale deployment. The requirements will almost certainly mean we would use the dovecot lda with the sieve plugin. The current method of distribution causes (binary distro) packaging to be slightly awkward IMHO. The dovecot-sieve code needs to be told where an in-tree build of dovecot lives. The fact that it _must_ be an in-tree build I was considering as a bug; the dovecot-sieve build wants to access both '.a' and '.h' files from the dovecot build but in an out-of-tree build these are in different places. My first thoughts were to simply move the dovecot-sieve code into the dovecot tree (I imagine under src/plugins/cmusieve or similar) and rework the autoconf setup as appropriate. This sidesteps the problem for this case but does not help other 'third party' dovecot plugins. If however a simple plugin build environment were to exist as part of a dovecot install then plugins could be distributed and built as independent packages. I quite understand that this additionally burdens dovecot development with 'stable API' concerns which may not be considered worth the effort. Timo: have you thought about any of the above and if so which direction have your thoughts taken you? I can justify spending a small amount of time to develop this into real code but it would be a waste to fight against or duplicate existing effort that has gone into this area. All comments welcome.

[Dovecot] leaking file descriptors? imap-login: inotify_init() failed
by Dale Bewley 15 Feb '07

15 Feb '07

Even though the system is configured to allow a large number of open files, and tools such as lsof tell me dovecot is within that limit; I am seeing errors like this pretty frequently. dovecot: imap-login: inotify_init() failed: Too many open files I'm running Fedora Core 5 (2.6.18-1.2257.fc5 SMP x86_64) with dovecot-1.0-1.rc15 built from the FC6 SRPM, but I was seeing the same thing with 1.0-0.beta8.3.fc5 (one of the reasons for the jump to the FC6 ver). # system default limit is very high, and we aren't approaching it [root@mail 2496]# cat /proc/sys/fs/file-max 738223 [root@mail fs]# cat file-nr 8704 0 738223 # the limit per user is 1024 [root@mail 2496]# su -c 'ulimit -n' dlbewley 1024 # But dovecot doesn't appear to be above that. # it looks like the master process is well below that [root@mail 2496]# lsof -p `cat /var/run/dovecot/master.pid` | wc -l 280 # but overall, this user has way more than that [root@mail fs]# lsof -nu dovecot |wc -l 3145 So, I raised the limit for dovecot to 5000 soft and 10000 hard to see if it would make a difference. Even after a reboot, the next day the errors returned. Today login_process_per_connection is set to 'no' rather than the default to see if it makes a difference. So far today, no errors.

[Dovecot] POP3-Proxy error
by Christian Froemmel 15 Feb '07

15 Feb '07

Hi, as mentioned in another thread I discovered a crash in the pop3-proxy. It occurs when the remote-pop3-server just drops the connection (in my case courier was hitting the MAXPERIP-Limit). I don't have a corefile yet, but will try to get one. Here the message from the dovecot.log: dovecot: Feb 02 09:30:00 Error: pop3-login: file pop3-proxy.c: line 20 (proxy_input): assertion failed: (!client->destroyed) dovecot: Feb 02 09:30:00 Error: pop3-login: Raw backtrace: pop3-login [0x8052fe0] -> pop3-login [0x8052ab4] -> pop3-login(vfprintf+0x2324) [0x804c6fc] -> pop3-login(vfprintf+0x2c9a) [0x804d072] -> pop3-login(vfprintf+0x1086) [0x804b45e] -> pop3-login(vfprintf+0x29d0) [0x804cda8] -> pop3-login [0x8056346] -> pop3-login [0x8055849] -> pop3-login(vfprintf+0x39d6) [0x804ddae] -> /lib/i686/libc.so.6(__libc_start_main+0xc7) [0x4015bd17] -> pop3-login(SSL_write+0x49) [0x804a931] dovecot: Feb 02 09:30:00 Error: child 5985 (login) killed with signal 6 It seems that the unexpected shutdown of the connection confuses dovecot. When I increased the MAXPERIP-limit in courier the crashes went away. regards, Christian -- SYSTEM CONCEPT GmbH

[Dovecot] master user
by Tom Bombadil 15 Feb '07

15 Feb '07

Greetings all... We are thinking about using the master DB, so a few admins can impersonate an ordinary user. So, we want to define one master for a set of users. And this administrator cannot be master of the other users? Can this be done somehow? Reading the docs, it seems that if a user is defined as master, it can login as everyone. Thanks for any hint.

[Dovecot] Startup errors
by Steven F Siirila 15 Feb '07

15 Feb '07

I just finished setting up a test Dovecot server (1.0-rc15, Solaris 10) and noticed upon start of Dovecot (after rebooting the server) that the imap-login and pop3-login processes spew errors as follows, which I can only assume is due to the fact that dovecot-auth has not fully initialized yet... it seems to me that these login processes are getting started too early, or should at least be waiting for dovecot-auth to get started.

[Dovecot] Q on configuring shared mboxes
by Mikhail Teterin 15 Feb '07

15 Feb '07

Hello! I have the following three types of mailboxes on my server: 1) Regular user mail /var/mail/<user> in mbox format 2) Suspected spam in /var/tmp/spamprobe in mbox format 3) Archived mailing list in /home/mks/mksarch in mbox format I want the 1) to be only accessible to the respective <user>, obviously (POP3 and/or IMAP4). I wanted the 2) to be accessible to all users -- and I want them to be able to move stuff out of it into their own mboxes (IMAP4 is enough). I want the 3) to be accessible _read only_ to anyone, who enters the correct username/password (preferably -- without creating a special Unix account). (IMAP4 or POP3) So far, I have only been able to achieve 1). Could someone, please, help me configure dovecot for the 2) and the 3)? Thanks! -mi

[Dovecot] lda sieve broken after upgrade

upgraded to rc19. using maildirs. solaris 9/cc. removed all modules from pop/imap/lda subdirs and first upgraded dovecot to rc19 and then used dovecot-sieve-1.0.1 sources to build against the dovecot source directory ( everything now builds nicely on Solaris, thank you Timo ). added "cmusieve" to the list of plugins used by lda. ail_plugins = cmusieve now getting this: deliver(lenny): Error: dlopen(/usr/local/dovecot/lib/dovecot/lda//lib90_cmusieve_plugin.so) failed: ld.so.1: deliver: fatal: relocation error: file /usr/local/dovecot/lib/dovecot/lda//lib90_cmusieve_plugin.so: symbol deliver_mail: referenced symbol not found anyone ? on the same machine, mbox based dovecot rc19 with dovecot ( sieve ) lda, works and upgraded without any issues, although the prior version must have been different, since the cmusieve statement was already present.

[Dovecot] auto-detection of user mailbox type - followup
by John Harper 15 Feb '07

15 Feb '07

In http://www.dovecot.org/list/dovecot/2006-December/018253.html Timo Sirainen wrote > > You can still change NAMESPACE_* environments. I don't remember how > exactly now, but you can do eg. "set > /tmp/sets" in the script, see > what it has set and modify them in the script. in response to my query regarding setting the mail_location in namespaces from a mail_executable script. The purpose of this is to be able to select on a per-user basis whether they're using Maildir or mbox format (I don't want to convert 12000 users all at once, and some users have no need or desire to change formats - they still use mail/elm etc) and also have the UW-IMAP compatibility namespaces to take care of all the clients currently configured with imap server directory = mail/. This all works, with one small bug left. For reference, here's the gist: In the dovecot.conf file place the usual namespace directives following the Namespaces wiki: namespace private { separator = / prefix = inbox = yes } #for UW backwards compatibility: namespace private { separator = / prefix = mail/ hidden = yes } namespace private { separator = / prefix = ~/mail/ hidden = yes } namespace private { separator = / prefix = ~%u/mail/ hidden = yes } define the mail_executable under protocol imap: mail_executable = /usr/local/dovecot/lbin/imap.sh and write the imap.sh script: ------start imap.sh--------------------------------------------------- #!/bin/sh # determine if user is in mbox or Maildir mode # Maildir takes precedence and is identified by the existence of # both a .procmailrc recipe and the Maildir directory. # Without a .procmailrc file, there's no recipe to force delivery in # Maildir format, so any existing Maildir is spurious # The .procmailrc should contain DEFAULT=Maildir/ # Set the absolute path to this script as the mail_executable for # the imap protocol in dovecot.conf. # It appears that this script is run as the user in their home dir if [ -f .procmailrc -a -d Maildir ]; then MAIL='maildir:~/Maildir'; export MAIL else MAIL='mbox:~/mail:INBOX=~/.mail'; export MAIL fi # each namespace defined in the conf file needs to have the mail # location defined which is set in environment vars # NAMESPACE_1 etc NAMESPACE_1=$MAIL; export NAMESPACE_1 NAMESPACE_2=$MAIL; export NAMESPACE_2 NAMESPACE_3=$MAIL; export NAMESPACE_3 NAMESPACE_4=$MAIL; export NAMESPACE_4 #debugging to see what else we can play with #set >> /tmp/d exec /usr/local/dovecot/libexec/dovecot/imap ------end imap.sh----------------------------------------------------- However, it appears that the root dir '~/mail' string is used at some point before the tilde-expansion takes place. I see a literal ~ directory in the users home, with an empty mail directory inside. After that it picks up the proper location and works correctly. I tried a %h and got a literal %h directory. So for now I made a simple workaround by using the absolute path to the home directory: # use home variable (depends on this script running in users home) # During startup it seems like ~/mail is interpreted as a string and # a spurious ~ folder is created, before the ~ is expanded home=`/bin/pwd` if [ -f .procmailrc -a -d Maildir ]; then MAIL="maildir:$home/Maildir"; export MAIL else MAIL="mbox:$home/mail:INBOX=$home/.mail"; export MAIL fi Thanks, John Harper ------------------------------------------------- Senior Systems Administrator Information and Instructional Technology Services University of Toronto Scarborough harper(a)utsc.utoronto.ca

[Dovecot] dovecot and libnss-ldap

Hi, I've been using dovecot 0.99.14 for a few years, with libpam-ldap and libnss-ldap, and never experienced any problem with those. I expect to soon switch to dovecot 1.0rc15 (or whatever gets available in Debian Etch, hopefuly dovecot 1.0), but I've seen some warnings against dovecot+libnss-ldap... Is the problem with libnss-ldap a recent problem (I mean it was not a problem with older dovecot such as my 0.99.14)? Is it still a problem even with 1.0rc22? Is there any hope to have it fixed before 1.0? Note that while most of the users I have to deal with are in my LDAP directory, a few ones are not and are in /etc/passwd. Hence, "userdb ldap" is probably not an option for me (and I'm quite happy with configuring all my servers with PAM and NSS). Cheers, Nicolas

[Dovecot] DoveCot compression to save HDD space
by Host Expert 15 Feb '07

15 Feb '07

Hello, I am wondering if there are any possibilities to save HDD space used by emails by compressing content (not just attachements). It would be many 1000s email boxes and probably each using lot of space so would be easier if we can just compress emails somehow. Thanks, Cristian

[Dovecot] Last login fields
by Dean Manners 15 Feb '07

15 Feb '07

Hey guys, Wondering if anyone has tried to do this before - a last login timestamp field. Using mysql for auth, I figured it would be easy enough to add a timestamp field and then tack an UPDATE statement on the end of the password_query. But of course, dovecot sees this as only one statement to pass to MySQL - of which MySQL barfs at.. Any ideas on how to achieve this ? Regards __________________________________________ Dean Manners

[Dovecot] Dovecot not responding
by Andrew Hoag 15 Feb '07

15 Feb '07

Hi all, I'm pulling my hair out on this problem and wanted to throw it out there to see if anyone else had run across it. I recently restarted my server. There were some network config issues that caused the interfaces not to come back up, but my colo company got those resolved. However, after restart, my IMAPS server has stopped responding to outside requests. I can successfully access IMAP from localhost, as well as via SSH tunnelling, so I know it is working. I've tried all sorts of "listen=" configurations, and checked lsof & tcpdump to rule out other problems, but it just seems as though dovecot isn't responding. TCPDUMP (notice the TCP SYN but no response): /var/log 89# tcpdump -vvs 192 port 993 tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 192 bytes 17:37:54.101518 IP (tos 0x0, ttl 112, id 56543, offset 0, flags [DF], length: 48) c-24-9-151-115.hsd1.co.comcast.net.3132 > mail.server.com.imaps: S [tcp sum ok] 1828791628:1828791628(0) win 16384 <mss 1460,nop,nop,sackOK> 17:37:58.282840 IP (tos 0x0, ttl 59, id 54721, offset 0, flags [DF], length: 60) dsl001-148-165.sfo1.dsl.speakeasy.net.39250 > mail.server.com.imaps: S [tcp sum ok] 3827175783:3827175783(0) win 5840 <mss 1460,sackOK,timestamp 1555809446 0,nop,wscale 2> 17:38:00.130267 IP (tos 0x0, ttl 112, id 56548, offset 0, flags [DF], length: 48) c-24-9-151-115.hsd1.co.comcast.net.3132 > mail.server.com.imaps: S [tcp sum ok] 1828791628:1828791628(0) win 16384 <mss 1460,nop,nop,sackOK> 17:38:01.283013 IP (tos 0x0, ttl 59, id 54722, offset 0, flags [DF], length: 60) dsl001-148-165.sfo1.dsl.speakeasy.net.39250 > mail.server.com.imaps: S [tcp sum ok] 3827175783:3827175783(0) win 5840 <mss 1460,sackOK,timestamp 1555810196 0,nop,wscale 2> LSOF: /var/log 91# lsof -i | grep imap sshd 4475 andrew 11u IPv4 39601 TCP localhost:34661->localhost:imaps (ESTABLISHED) dovecot 6540 root 5u IPv4 38988 TCP *:imaps (LISTEN) imap-logi 6599 dovecot 9u IPv4 39602 TCP localhost:imaps->localhost:34661 (ESTABLISHED) imap-logi 6629 dovecot 1u IPv4 38988 TCP *:imaps (LISTEN) imap-logi 6630 dovecot 1u IPv4 38988 TCP *:imaps (LISTEN) NETSTAT: /var/log 92# netstat -an | grep 993 tcp 0 0 0.0.0.0:993 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:993 127.0.0.1:34661 ESTABLISHED tcp 0 0 127.0.0.1:34661 127.0.0.1:993 ESTABLISHED STRACE: 17:00:33.225030 gettimeofday({1171501233, 225048}, {480, 0}) = 0 17:00:33.225072 gettimeofday({1171501233, 225090}, NULL) = 0 17:00:33.225113 poll([{fd=7, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=10, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=3, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=1, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 4, 0) = 0 17:00:33.225163 gettimeofday({1171501233, 225182}, {480, 0}) = 0 17:00:33.225212 gettimeofday({1171501233, 225230}, NULL) = 0 17:00:33.225260 poll([{fd=7, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=10, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=3, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=1, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 4, 999) = 0 17:00:34.225145 gettimeofday({1171501234, 225179}, {480, 0}) = 0 17:00:34.225204 gettimeofday({1171501234, 225222}, NULL) = 0 17:00:34.225246 poll([{fd=7, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=10, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=3, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=1, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 4, 0) = 0 17:00:34.225297 gettimeofday({1171501234, 225315}, {480, 0}) = 0 Has anyone seen this behavior?

Suggestions much appreciated, I'm stuck. I'm sure this is something obvious and simple, but I'm looking past it right now.

[Dovecot] OT: looking for plugin developer
by Tom Bombadil 15 Feb '07

15 Feb '07

Greetings all, We are looking for a developer to write a plugin that copies the message to a specific hidden folder called "spam_copy" when a message inside a folder called "spam" is viewed for the first time. And when we move the message from the "spam" folder to any other folder, and if the message hasn't been seen, we should send a copy of it to "spam_copy" hidden folder, in addition to the move. If anybody is up for it, please send me a private message, so we can arrange all the details, payment, etc... Thanks in advance.

[Dovecot] incorrect quota reporting with dict quota
by Marshal Newrock 14 Feb '07

14 Feb '07

Using the dict quota with dovecot-1.0.rc21, quota reporting was incorrect. It wasn't just that the stored quota was different than the disk usage, but also that each time the quota was checked, it was greater than before, even if no mail was received. I tested this by using telnet to log into an imap account, and issuing multiple "getquotaroot inbox" commands. I have changed to just using maildir quotas, and everything seems correct now. Thanks to dovecot's flexible authentication methods, I'll be able to set an individual account to use the dict quota backend for testing. -- Marshal Newrock, Ideal Solution LLC http://www.idealso.com

[Dovecot] environment variables required for startup
by Marshal Newrock 14 Feb '07

14 Feb '07

Using dovecot-1.0-rc19 (quotas are working good, btw) on Gentoo, I have a strange problem. On boot, dovecot doesn't start, the init script just times out. From the command line, it starts instantly without problem. Also, using a program called 'monit' to make sure processes stay running and restart them if they stop, if I manually stop dovecot, it is then unable to start it (calling the init script). Nothing gets logged. In all cases, it's "/etc/init.d/dovecot start". The only thing I can think of is that there's some environment variable required which isn't being set. monit specifically says it unsets everything except for a basic path before running the start program. Do any environment variables need to be set in order for dovecot to start successfully? -- Marshal Newrock Ideal Solution, LLC - http://www.idealso.com

[Dovecot] migration question: "imap server directory"
by Dan Price 14 Feb '07

14 Feb '07

In prepping our IMAP migration to Dovecot, I've hit upon a small issue: the "IMAP server directory" which Thunderbird users have set in the "advanced" prefs. Our old IMAP server seems to set your current directory to ~. This wound up causing users to set their IMAP server directory to "/home/<user>/mail/" so that their mailboxes would be found: --> A104 LIST "/home/dp/mail/" "%" * LIST (\NoSelect) "/" /home/dp/mail/ * LIST (\NoInferiors \UnMarked) "/" /home/dp/mail/sent-mail-Jul-2006 * LIST (\NoInferiors \UnMarked) "/" /home/dp/mail/sent-mail-Dec-2004 ... A104 OK LIST completed Of course, relative paths also work, but it seems that not many users are using them: --> A105 LIST "mail/" "%" * LIST (\NoSelect) "/" mail/ * LIST (\NoInferiors \UnMarked) "/" mail/sent-mail-Jul-2006 * LIST (\NoInferiors \UnMarked) "/" mail/sent-mail-Dec-2004 ... A105 OK LIST completed Also, it turns out that some users have mail in "mail" and some in "Mail". So for now, with Dovecot, I've set: mail_location = mbox:~:INBOX=/var/mail/%u:INDEX=%h/Mail/imapd-indices But users with absolute paths are having issues: A102 LIST "/home/dp/mail/" "%" A102 OK List completed. Versus: A103 LIST "mail/" "%" * LIST (\Noselect \HasChildren) "/" "mail/" * LIST (\NoInferiors \UnMarked) "/" "mail/sent-mail-Jul-2006" * LIST (\NoInferiors \UnMarked) "/" "mail/sent-mail-Dec-2004" A103 OK List completed. I've read the MailboxLocation page on the Wiki, but I'm not sure of the best way to proceed and have things stay compatible for my users. It is possible to ask all users to change, but I'm going to have to field a lot of questions if I ask users for that :/ Thanks! -dp -- Daniel Price - Solaris Kernel Engineering - dp(a)eng.sun.com - blogs.sun.com/dp

[Dovecot] info deleted messages imap
by Hola 14 Feb '07

14 Feb '07

Hi! I want to know the number of messages deleted when the mail user connect by IMAP protocol. When the user uses POP, we got this directive in the configuration file: pop3_logout_format = top=%t/%p, retr=%r/%b, del=%d/%m, size=%s This is the log: dovecot: Feb 09 02:31:02 Info: pop3-login: Login: user=<xxxxxx>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured dovecot: Feb 09 02:31:02 Info: POP3(xxxxx): Disconnected: Logged out top=2/3756, retr=0/0, del=0/7, size=17392 If you look at "del=0/7" we know that user deleted 0 messages. When the user log in the account by IMAP protocol, appears the following: dovecot: Feb 09 02:02:36 Info: imap-login: Login: user=<xxxxx>, method=PLAIN, rip=82.xxx.xxx.xxx, lip=82.xxx.xxx.xxx dovecot: Feb 09 02:03:02 Info: IMAP(xxxxx): Disconnected: Logged out And we donÂ´t know the number of messages deleted, the question is: there is any directive like "pop3_logout_format" applied to IMAP?? Something like "imap_logout_format" ?? Dovecot version: 1.0.rc17.

[Dovecot] Rawlogs in freebsd?
by Francisco Reyes 14 Feb '07

14 Feb '07

I am trying to enable rawlogs. I made a directory /home/dovecot/dovecot.rawlog/, changed dovecot.conf to have mail_executable = /usr/local/libexec/dovecot/rawlog /usr/local/libexec/dovecot/imap Made sure the /home/dovecot/dovecot.rawlog/ could be written to. Even made it 1777 as a test. Made sure the FreeBSD user database points /home/dovecot as the dovecot user's directory (left shell as nologin). Compiled dovecot from ports and using Dovecot 1.0.r21. Still no rawlog. Any pointers?

[Dovecot] resilience suggestion
by David Lee 14 Feb '07

14 Feb '07

On the whole we are pleased with our trials of dovecot to replace UW-IMAP. But (ah!) we have hit one particular problem, in which we think dovecot could probably benefit from a resilience improvement. We're running dovecot on Fedora Core 5 (FC5), with passwd map details supplied by NIS. We have found that "nscd" sometimes thinks that a username is invalid, even though it is valid. So when "deliver" attempts a delivery to the INBOX of that username, it receives "user unknown" from the name service, and then does a 5xx permanent failure of valid email. >From the user perspective "The System" has incorrectly rejected perfectly valid incoming email. It is rare, but it does occasionally happen on large, busy systems. Clearly it is fundamentally an "nscd" bug. But that bug is nevertheless out there, in the wild, on such systems, potentially affecting dovecot's delivery of valid user email. We have had a source code hack since October (in "deliver.c", simply replacing a "return ret" occurence with "return EX_TEMPFAIL") and it has worked nicely (ported forward from rc8 towards rc22). Mail re-queues and a later delivery attempt then succeeds. So it would be both helpful, and good for resilience against such real OS/nscd bugs (and similar), if there were a configuration option in dovecot to allow a site admin to tell deliver to use a temporary, 4xx, failure instead (if the circumstances were appropriate for the site). Could this be considered please, Timo? -- : David Lee I.T.

[Dovecot] Ubuntu, Exim, deliver: permissions/setgid problem
by Sam Hathaway 14 Feb '07

14 Feb '07

Hello all, I have a little problem. I'm trying to set up Dovecot deliver (1.0 beta 3) as the LDA for Exim4 on Ubuntu 6.06 with MBOX, and I'm running into permissions problems. Exim typically wants to run pipes as the user to whom the mail is being delivered (as per the "check_local_user"). deliver needs access to the auth socket and needs to be able to create files in /var/mail. In Ubuntu, /var/mail is writeable by group mail, but not by others. So I thought I'd make deliver run as the user to whom the mail is being delivered (as per default) and with group "mail" (so it can create files in /var/mail). I also set the auth socket to be group-writeable and gave it the group mail. So theoretically, deliver should be able to: - connect to the socket - create dotfiles in /var/mail - write to the user's mailbox The problem I'm running into is that deliver tries to setgid to the primary group of the target user, and dies when it can't. I specifically do NOT want it to do this, because regular users don't have permission to write to /var/mail. I've also tried making deliver SUID root (as recommended on this list) or SGID mail (like procmail is) but I get the same error. If I also disable the "group = mail" line in the dovecot_deliver_user router in exim4.conf, I still get the same error. If I disable the "group = mail" line without making deliver SUID or SGID, then it can no longer connect to the auth socket. In this case it runs with the group of the user for whom the mail is being delivered, i.e. sam-adm (#10000). I've also tried adding "user = mail" to the transport, to no avail. The ONE way I've been able to make it work is to remove "group = mail" from exim4.conf and set the socket's mode to 0666, but I've seen warnings that allowing world-access to the socket is dangerous. I'm actually not sure why this works, since in this case it's running with both the UID and GID of the target user, and therefore shouldn't be able to create files in /var/mail. Can anyone untangle this for me? From what I've read, in Debian delivery agents should run with group "mail" (procmail is SGID mail). It seems to me that the way to go is to spawn it with group mail, allow group mail access to the auth socket, and be done with it.

[Dovecot] http://wiki.dovecot.org/VirtualhostingWithExim
by Marc Haber 14 Feb '07

14 Feb '07

Hi, Here is a new wording for the "Exim4 on Debian" part of the web page on http://wiki.dovecot.org/VirtualhostingWithExim. It's immutable, so I cannot directly change it. I e-mailed Florian, but he cannot log in to the wiki any more. Can somebody with appropriate privileges change the page? --------------------- If you are using the exim4 packages on Debian, you need to pay attention whether you are using the split or non-split configuration method that the packages offer. If you are using split-configuration, you need to apply the configuration changes to the router and transport directories inside /etc/exim4/conf.d; if you are using non-split configuration, you need to edit /etc/exim4/exim4.conf.template. A restart of the exim daemon with /etc/init.d/exim4 reload will activate your changes. You can find more information about the way Debian configures the exim4 packages in /usr/share/doc/exim4-base/README.Debian or at http://pkg-exim4.alioth.debian.org/README/README.Debian.html or at the Debian wiki (http://wiki.debian.org/PkgExim4) --------------------- Additionally, I would appreciate if the instructions for exim 3 could be removed. exim 3 is obsolete five years now, and new users of exim 4 are constantly finding old exim 3 documentation and fail in applying that docs to exim 4.

[Dovecot] dead bodies stacking up in Drafts folder
by Charles Bueche 14 Feb '07

14 Feb '07

Hi, Setup : Apple Mail 2.1.1 (752.3) on Intel MacBook Pro and Dovecot 1.0rc22 on Solaris 9/SPARC. I use IMAP/TLS. Problem : mails are stacking up in the Drafts folder. When I start writing a mail, it appears in the drafts folder, and usually disappear as desired when I hit "Send". It then appear in the "Sent" folder. Sometimes, a draft versions stays in "Drafts", I have 21 of them since 1.1.2007. In this period, I have written about 400 emails, so only about 5 % stick in "Drafts". I can of course periodically select and delete them, but I don't like such glitches. Never sure if emails are really sent. Advice welcome. I'm the Solaris packager and admin so I can test things if needed. Sorry if it's a known Apple Mail issue, I would be the one to beat for using closed-source stuff :-) Charles -- Charles Bueche <charles(a)bueche.ch> sand, snow, wave, wind and net -surfer A-Cat SUI 192

[Dovecot] Apple mail

13 Feb '07

I have strange situation with Appe mail and latest (rc22) Dovecot. I using "mbox" POP3 (not IMAP) type of message box on server (exim: driver=appendfile) I also using MySQL authentification and SSL. Server - Linux Slackware 11.0 Linux/Thunderbird, WinXP/Thunderbird, WinXP/Outlook clients are working fine with their message boxes. But Apple mail doesn't delete messages in user's mbox, so client gets a lot of duplicate messages. As I see in such a mbox, there isn't system message like: >From MAILER_DAEMON Tue Feb 13 14:41:08 2007 Date: Tue, 13 Feb 2007 14:41:08 +0000 From: Mail System Internal Data <MAILER-DAEMON@mail> Subject: DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA Message-ID: <1171377668@mail> X-IMAP: 1169824263 0000000019 Status: RO But every message in such a box marked as "Status: RO" Please, help me to solve this trouble.

[Dovecot] PAM, NSS, and a new blocking=yes setting
by Timo Sirainen 13 Feb '07

13 Feb '07

I wondered for a while if I should do this before v1.0, but since there seem to be problems with some PAM/NSS users and this was way easier to implement than I realized, here it is: passdb pam and userdb passwd now support blocking=yes setting in their args. For PAM the default has been to fork the dovecot-auth process and talk via a pipe to the main dovecot-auth. I've never really liked this approach, but didn't bother fixing it before. However it is also what has caused the bugs with nss_ldap, and maybe with other NSS backends too. NSS lookups then have been done all in the same dovecot-auth process without any forking. This meant that if it got stuck (or delayed a bit in LDAP queries and such), the whole dovecot-auth got stuck and all authentication attempts got stuck. With blocking=yes the lookups are handled in dovecot-auth worker processes. Earlier these workers have been used only with MySQL. Initially there is only a single worker process, but whenever dovecot-auth notices that there are no free workers while a new auth request comes, a new worker is created. auth_worker_max_count specifies the maximum number of those processes. This blocking=yes will probably work great with NSS. With PAM I'm not so sure. Mostly because the worker never exits, it just does one PAM auth after another. I think usually PAM is used only once in a process, so there might be memory leaks and maybe other bugs.. Then again, maybe not. I'll add some auth_worker_max_requests setting which can be set to 1 if this is a problem. Also for blocking=no case I added code to send KILL signal to PAM child processes which haven't replied for 2 minutes. With blocking=yes this condition can't be checked currently. http://dovecot.org/list/dovecot-cvs/2007-February/007639.html http://dovecot.org/list/dovecot-cvs/2007-February/007642.html http://dovecot.org/list/dovecot-cvs/2007-February/007646.html

[Dovecot] MD5-CRYPT passwords in a MySQL Database
by David Mills 13 Feb '07

13 Feb '07

First of all, hello to the list. I'm currently migrating from a /etc/passwd and /etc/shadow based configuration to a MySQL based one using dovecot 99.14 on debian sarge. The problem is that the /etc/shadow containes both DES encoded (Crypt) and md5 based passwords. I've set the default system to be Crypt, and have added {MD5-CRYPT} in front of the md5 passwords in place of the $1$ header found in /etc/shadow. But I can only log in on accounts that have DES based passwords. I've included my dovecot configuration, and below are 2 examples of encoded password, one crypt and one MD5: XalGYN3cy1crA {MD5-CRYPT}RL$Bvv.TF2XJkyVI6JOUO8tx/ If anyone has any ideas I'd really appreciate them since 80 odd accounts have this problem, so changing them one by one will be difficult.

[Dovecot] Problems with HUP'ing dovecot
by Javier Henderson 12 Feb '07

12 Feb '07

Hi, I'm running dovecot 1.0.rc7 on FreeBSD 6.1, so far with great success. Earlier today I tried to HUP the main process, the following was logged: dovecot: Feb 12 15:10:19 Warning: SIGHUP received - reloading configuration dovecot: Feb 12 15:10:19 Panic: file ioloop-poll.c: line 105 (io_loop_handle_remove): assertion failed: (index >= 0 && (unsigned int) index < ctx->fds_count) Of possible interest: just prior to issuing the HUP I had edited the / etc/resolv.conf file to take out the first entry since that particular DNS server went off line. I noticed that login attempts to the POP and IMAP services were timing out and that's when I sent the HUP to dovecot. Any ideas? Thanks, -jav

[Dovecot] mail_location and storage type
by Jürgen Herz 12 Feb '07

12 Feb '07

Hi, I was setting up a new system for testing Dovecot 1.0. My old one is using 0.99 and was set up quite a time ago, so I had to consult the documentation. I needed several attempts until it worked and that was because the designated maildir directory /server/mail/jrg/Maildir was completely empty. Upon login the server exited and wrote the following to the log: POP3(jrg): Ambiguous mail location setting, don't know what to do with it: /server/mail/jrg/Maildir (try prefixing it with mbox: or maildir:) POP3(jrg): Failed to create storage with data: /server/mail/jrg/Maildir That thing was the main cause of my confusion since the config wasn't ambiguous at all at already contained a prefix: mail_location = maildir:/server/mail/%u/Maildir The wiki article MailLocation doesn't contain any hint maildirs have to contain at least a cur subdirectory. That information I eventually got from mail-storages.txt - that file must be one for which the wiki isn't an alternative. So what is this mail about? 1. The log message is wrong or at least missleading. Would be fine if it could get improved. 2. Is there any reason at all to have a storage prefix but still require some special format for the directory in order to recognize it? 3. At least if the behaviour will stay, shouldn't the text from mail-storages.txt converted to a wiki article or incorporated into MailLocation? Regards, Juergen

[Dovecot] Differences between IDLE when Maildir vs. wel the "mail" folder is used
by Philip Van Hoof 12 Feb '07

12 Feb '07

Are there any differences with how both IDLE and "UID FETCH n:n+x (FLAGS UID...)" are handled when Dovecot is using a "mail" vs. a "Maildir" user? I have recently implemented support for IDLE (Push E-mail) in a client infrastructure that I'm building. I haven't in depth checked out what the problem might be, but when Dovecot was using the "mail" dir in $HOME something about the implementation wasn't working. When I switched to "Maildir" everything worked. I only tested to the point of seeing the "* EXISTS n" response during the idle. I saw this response. It's for example possible that the n is wrong or that a bit later the "UID FETCH ..." ain't returning the right information. It's also possible that my implementation is wrong (of course) and I haven't yet had the time to really figure out what goes wrong. I did so far, however, test with Cyrus, Exchange, Courier and Isode's M-Box. All these tests where successful. SO if it indeed is a discrepancy in my implementation .. it's going to be something very specialised or specific I fear :-) I also setup testing infrastructure http://tinymail.org/trac/tinymail/wiki/TestImapServers Also take a careful look at this manual test. "tnytest" is a user on imap2.tinymail.org that uses Maildir. The "tnytest2" user doesn't have a Maildir configured. By that I mean that "Dovecot" has created the folder for E-mail using whatever it uses by default. Dovecot's IDLE (the EXISTS) responses also take a lot longer on tnytest2 than on tnytest. Another question. Why not simply "always" use the Maildir solution if that one works better? ;-) (really, honest question. Hehe). Take a look at the "UID FETCH" response: It's incorrect on tnytest2. The first attempt I asked for 1:1 and I got none. The second I asked for 1:4 and I got 3 of them, while IDLE clearly stated that there where 4 messages available. In reality 4 where indeed available (or copied in total). Well, I'm not saying something is or isn't wrong, just wondering and testing a little bit and seeing some strange results... Feel free to use imap2.tinymail.org for testing. And if you need root on that virtual machine, so that you can install a new version, go ahead.

[Dovecot] PLAIN-MD5 password scheme with salt?
by Steffen Weber 12 Feb '07

12 Feb '07

Hello! I'm storing passwords as MD5 hashes in a MySQL database and have specified "default_pass_scheme = PLAIN-MD5" in dovecot-sql.conf. Can Dovecot append or prepend a salt to a password before hashing them? Because without salt the plaintext passwords can be restored from the MD5 hashes using rainbow tables. Greetings Steffen Weber

[Dovecot] mbox and dual-use folders?
by John Robinson 12 Feb '07

12 Feb '07

Feature request: please can we have support for messages stored in mbox files, but folders containing both messages and folders. I think this could be done for a folder called e.g. dovecot-list by having an mbox file called dovecot-list and a directory called dovecot-list.folder (or whatever, says he handwaving away name clashes which can be worked around like they are in maildirs). This may be a subset or variant of http://wiki.dovecot.org/FeatMboxMaildir Cheers, John.

[Dovecot] IMAP/POP3 server with proxy feature
by Jasper Bryant-Greene 12 Feb '07

12 Feb '07

We are currently evaluating the migration from a proprietary, legacy mail server onto Dovecot for 20,000+ virtual domains. This is a big job and we intend to do it by initially proxying connections through to the legacy server, and moving customers over in batches by turning off the proxy feature for them. In the manual it states "This model is still a bit unfinished in current code" [1]. What is needed to get this production-quality? I'm happy to help out with any work required.

[Dovecot] Shared folders plans for the future
by Timo Sirainen 11 Feb '07

11 Feb '07

So while driving for several hours in my car recently and having nothing else to do, I started thinking how they could be done. I think the "public folders" configuration will stay as it is now. Does it really even need anything else? The problematic case is how the users can share their mailboxes to other users. There are two problems related to it: 1) How to get (quickly) a list of another user's mailboxes that I have access to? 2) How to get quickly a list of all users who have mailboxes that I have access to? The 1) problem is easier to solve. Create a directory listing all the mailboxes that are shared to at least someone (have ACLs set). It could be configured like: namespace shared { # IMAP namespace prefix, %u expands to shared user prefix = user/%u/ # Directory containing symlinks to user's all shared mailboxes share_dir = ~/Maildir/shared # Where to store indexes for other users' accessed mailboxes index_dir = ~/Maildir/others-indexes } The ~/Maildir/shared directory could then contain symlinks to all the shared mailboxes. The directory list could probably be in Maildir++ layout even though the symlinks would point to mboxes. This requires adding code that can handle mixed maildir/mbox directories, but it'll come anyway.. The 2) problem is more difficult. There are 3 choices: a) Use a shared database file. lib-dict could be used for this, so the database could be in SQL or in a berkeley db file. The downside to this is that the file needs to be readable and writable to everyone, so if users have shell access the users could break the file. They dictionary would contain data in format "<destination_user>/<sharing_user>" = 1 and "<destination_group>/<sharing_user>" = 1, ie. the value would be ignored and only the existence of the keys would be important. Then iterating through "<my_username>/*" and "<all_my_groups>/*" would list the users who probably have mailboxes where I have access to. b) Use a directories with sticky bit set. Well, basically the same idea as in a), except filesystem would be used. Actually perhaps this could be made another lib-dict backend.. c) Brute force: Just assume everyone potentially have shared mailboxes. Get the list of users by readdir()ing through /home (configurable). I guess each of these could be made an option.. So something like: namespace shared { .. # a) shared_dict = db:/var/lib/dovecot/shared-mailboxes.db # b) shared_dict = dir:/var/lib/dovecot/shared-mailboxes # c) shared_dict = bruteforce:/home } I'm currently also implementing a "mailbox list index", which contains a list of all the user's mailboxes and some useful metadata for them, such as number of messages and so on. So that STATUS command wouldn't need to open the mailbox index files if they haven't changed. The mailbox list index updating is normally done when directory's mtime has changed. For list of shared users that would also work in 2b) and 2c) cases, but for 2a) I'd either have to always sync everything or alternatively add some sequence/<dest_user/group>=# value which is grown for each update, and the syncing is done only when the sequence is updated.

[Dovecot] help needed - dovecot-ldap authentication
by Vidyasagar Warge 10 Feb '07

10 Feb '07

I am trying to set a up mail server on a ubuntu edgy machine. I followed the howto at http://wanderingbarque.com/howtos/mailserver/mailserver.html . I am able to configure everything except dovecot-ldap authentication :(. After struggling with it for a week I decided to seek help. The current version of dovecot is v1.0 RC21 and the version used for the howto is v0.99.10.9. I installed & tried to configure both versions but none of them was able to authenticate a user from ldap. I noted some differences in syntax of the dovecot.conf files of both the versions. It seems that the ldap documentation at dovecot site is from the old version of dovecot ( I might be wrong on this!). So if anyone can tell me how to configure the current version of dovecot with openldap? Please help me! I am eagerly waiting for your response. Regards, Vidyasagar

[Dovecot] Lda does not query pgsql
by Tognini Samuele 09 Feb '07

09 Feb '07

Hi, I don't know if it's a bug or my configuration fault, but LDA does not work as i expect. Dovecot auth connects to a pgsql database that mirrors Nis users infos, but it has also quota settings because i'd like to use a per-user quota environment. Mailserver and Postfix authenticates users with Nis (through PAM), while imap and local delivery (with the postfix mailbox_command setting) are left to dovecot mechanism. Imap works perfectly, dovecot retrieves authentication and quota setting from database, but dovecot LDA seems to not query any database (and nothing is logged) , so that quota is not retrived and message is not bounced when user is overquota. You can see it in the verbose log: deliver(tognini): 2007-02-08 12:25:02 Info: Loading modules from directory: /usr/lib/dovecot/modules/lda deliver(tognini): 2007-02-08 12:25:02 Info: Module loaded: /usr/lib/dovecot/modules/lda/lib10_quota_plugin.so deliver(tognini): 2007-02-08 12:25:02 Info: Module loaded: /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin. so deliver(tognini): 2007-02-08 12:25:02 Info: mbox: data=/home/t/tognini:INBOX=/var/spool/mail/tognini deliver(tognini): 2007-02-08 12:25:02 Info: mbox: root=/home/t/tognini, index=/home/t/tognini, inbox=/var/spool/mail/tognini deliver(tognini): 2007-02-08 12:25:02 Info: cmusieve: Using sieve path: /home/t/tognini/.dovecot.sieve deliver(tognini): 2007-02-08 12:25:02 Info: msgid=<20070208112502.7706B3273D6(a)arturo.cli.di.unipi.it>: saved mail to INBOX If i set quota variable in dovecot.conf, still no query but the global variable is used for all users: ... deliver(tognini): 2007-02-07 12:33:04 Info: dirsize quota limit = 1024kB ...

[Dovecot] why is there email in my mbox file?
by Kendall Shaw 09 Feb '07

09 Feb '07

Hi, I've installed dovecot-imapd under ubuntu. My account and root are the only email accounts on my computer. I transitioned from using GNUS with fetchmail, exim and movemail, to gnus with exim, fetchmail and imap, so I've kept the mbox format email instead of changing to maildir. This works okay, except my mbox file is giant. I expected dovecot to take the mail out of the mbox file and put it somewhere. But, I see there's a big mbox file (/var/mail/me) that keeps growing. Is dovecot using that as the store of messages? If I were to move to using maildir instead of mbox, what is going to happen to my existing mail? Kendall

[Dovecot] Feature Request
by Jay Chandler 09 Feb '07

09 Feb '07

How much trouble would it be to have the name of the .subscriptions file set via the configuration file, or failing that, as a compile-time option? I find that editing the source directly is a bit of a harrowing experience, particularly when doing it as part of a package management system such as an RPM or the FreeBSD ports tree. -- Jay Chandler Network Administrator, Chapman University 714.628.7249 / chandler(a)chapman.edu Today's Excuse: Too many interrupts

[Dovecot] Folders compat. problem ?
by Frank Bonnet 08 Feb '07

08 Feb '07

Hi A user here has a strange problem when I moved my imap server from UW-IMAP to Dovecot. A folder created monthes ago with mozilla mail (windows client) became suddenly invisible when I stopped UW then started Dovecot. I really think that IMAP created folders a fully compatibles between UW and Dovecot but I'm curious to know from where does come this trouble ??? Anyone had experienced the same problem ? Thanks a lot.

[Dovecot] POP3 UIDL
by FiL ＠ Kpoxa 07 Feb '07

07 Feb '07

I have installed rc22 and tried it with my mbox-based mail - fine. Then I converted that mbox to Maildir to see if new feature (saving state without QUIT) works - first run - I get time out. Second run - I get rest of the Maildir scanned and get into mailbox. Fine. but.... # telnet enders2 110 Trying 127.0.0.1... Connected to localhost.localdomain (127.0.0.1). Escape character is '^]'. +OK Dovecot ready. user filonovd +OK pass ****** +OK Logged in. uidl +OK . where is the list of pop3 uids ? When I connect to mbox I get something like .......... 84904 d8f096c72c24719bd7d13d78a3694114 84905 9074b40ab4283ec38a151587f34690d9 84906 06a40afeaca43fc76bea2231b13b1a33 84907 cdae771ec2407df89a25321f3792d9e9 84908 9f84415625d77dd3cde7d9441847318e but with Maildir I get nothing.

[Dovecot] negative quota usage causes over-quota messages with dictionary quota backend
by Marshal Newrock 07 Feb '07

07 Feb '07

Using dovecot 1.0.rc21, with quotas being stored in mysql, I have found that if the quota usage stored is negative, then when a message is given to dovecot deliver, the account is reports as being over quota. The squirrelmail quota usage plugin says that the quota is at around 40 million percent (I should have written down the exact number), though I don't know if that's squirrelmail or dovecot coming up with that number. At a guess, I'd say there's an unsigned int being used where the result can be signed. I'm using MySQL 5, so for an easy workaround, I added a trigger that sets the quota usage to 0 if it goes less than 0. I could probably also set the field to unsigned int, but I haven't tested what mysql does if you try to change an unsigned int field such that it would be negative. -- Marshal Newrock, Ideal Solution LLC http://www.idealso.com

[Dovecot] OTP?
by Micah Cowan 07 Feb '07

07 Feb '07

Hello, I was wondering where I might find more information about using OTP as an authentication protocol with dovecot. In searching, I found a thread from 2004, but not much information about how it has progressed from then. I also saw some promising patches from mid-last year, which if I had to guess are probably the addition of support for the SASL OTP mechanism. Is this available in a release yet? (And, also: does anyone know of Linux mail clients that support the OTP SASL mechanism? I'm hoping Thunderbird might...). If not, is it possible to make it work currently with PAM (or, if that's not possible, maybe Cyrus SASL)? It would be okay with me if it can work with PAM but not prompt with the seed/series number: I can scratch off keys no prob. I tried briefly to get it to work through PAM, and in fact opieinfo told me that the series was being decremented, but auth.log gives Feb 6 15:41:46 mabruk dovecot-auth: (pam_unix) authentication failure; logname= uid=0 euid=0 tty= ruser= rhost=x.x.x.x user=micah ssh works fine with the same PAM settings (both include common-auth, which has:) auth sufficient pam_opie.so auth sufficient pam_unix.so nullok_secure auth required pam_deny.so -- Micah J.

[Dovecot] imap crashes on deleting an e-mail with no message-id.
by Tan Shao Yi 07 Feb '07

07 Feb '07

Hi, I'm on RC21 on a Solaris 10 SPARC box. Somehow I managed to receive an e-mail with no message-id and when dovecot tries to delete the e-mail. Viewing the e-mail is not a problem though. I attached truss to the imap process and this was what I received: pollsys(0x000B7A88, 3, 0xFFBFF870, 0x00000000) = 0 pollsys(0x000B7A88, 3, 0xFFBFF870, 0x00000000) = 0 pollsys(0x000B7A88, 3, 0xFFBFF870, 0x00000000) (sleeping...) pollsys(0x000B7A88, 3, 0xFFBFF870, 0x00000000) = 1 read(0, " g 1 b q U I D S T O".., 3747) = 52 alarm(120) = 0 fcntl(6, F_SETLKW64, 0xFFBFF1D0) = 0 alarm(0) = 120 close(8) = 0 open64("/maildirs/tansy/Maildir/maildirsize", O_RDWR|O_APPEND) = 8 read(8, " 1 0 7 3 7 4 1 8 2 4 0 S".., 5120) = 2223 read(8, 0xFFBFE8DF, 2897) = 0 Incurred fault #6, FLTBOUNDS %pc = 0x00086FF8 siginfo: SIGSEGV SEGV_MAPERR addr=0x00000000 Received signal #11, SIGSEGV [default] siginfo: SIGSEGV SEGV_MAPERR addr=0x00000000 I believe it's due to the mail_log plugin that is logging the message-ids being deleted. When I disabled the mail_log plugin, the e-mail gets deleted correctly. Timo, do you think we can have mail_log to handle such exceptions? :) Thanking in advance. Cheers, Tan Shao Yi

[Dovecot] Default domain name

07 Feb '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi! I'm trying to setup a dovecot installation and at the same time i'm also moving from system to virtual users. In order for end-users to experience as little impact as possible, I'd like to add a default domainname to the login, if the login doesn't contain a full username. For instance: * User logging in as "user(a)mydomain.com" will get the mailbox for user(a)mydomain.com. * User logging in as "user" will also get the mailbox for user(a)mydomain.com Is there some way to do this, without using the pop3/imap proxy? I've searched the wiki and sample configuration file, but was only able to find entries about authentication rewrites so far, and I don't know if this could be done with auth_username_translation ?

[Dovecot] Indexing Performance Question (was tpop3d vs dovecot)
by Nate 06 Feb '07

06 Feb '07

Since posting the previous thread we've setup a new system (Opteron 2.0ghz, 1gb ram, Fedora 6) for testing. I am hoping somebody very familiar with the indexing portion of dovecot can shed some light on this for me. After much testing, I've come to one primary conclusion that dovecot is possibly unnecessarily scanning or reading files within the maildir directories. Take a mailbox for instance (my test one has 71570 emails in the cur/ folder so the process runs long enough to get data of what it's doing). Follow these steps: 1. First pop3 connection. With no index files whatsoever, it takes nearly a full 10 minutes at 100% io load to scan the 71570 files (748M) directory and build the index files from scratch which look like this: -rw------- 1 postfix postdrop 839K Feb 1 00:43 dovecot.index -rw------- 1 postfix postdrop 1.9M Feb 1 00:57 dovecot.index.cache -rw------- 1 postfix postdrop 560K Feb 1 00:43 dovecot.index.log -rw------- 1 postfix postdrop 3.1M Feb 1 00:43 dovecot-uidlist While it's building index i see a lot of these fly by in lsof pop3 2023 postfix 8r REG 8,3 14425 285947 /var/spool/mail/test.visp.net/natetest/cur/1128488047.V902I7d42e.s3.visp.net:2, No problem here, the disk can only go as fast as the disk can go and thats a *lot* of mail. Although, one curious thing here, it appears that dovecot is reading or at least scanning the entire contents of the files within the cur/ directory to generate an index. I assume this by watching my disk cache go from 100MB to 600MB. Is it necessary to do that or only read the top X lines of each file, is that even possible? 2. Second connection. Near instantaneous results from a login and LIST. Cannot perform an lsof fast enough to see what files it's opening. This step can be repeated with nearly the same results. *rebooted machine to clear all cache* 3. Third connection. It takes ~40 seconds to display a LIST after login. The index files are untouched; however, during the 40 seconds I'm waiting, I can catch a few of these in lsof. pop3 1971 postfix 10r REG 8,3 4196 205963 /var/spool/mail/test.visp.net/natetest/cur/1157863512.V902I1f3867.s3.visp.net:2,S This tells me even though there is no new email, it is re-scanning the cur/ directory somewhat. It doesn't take near as long as the initial index build, but certainly takes longer than it would for the system to read any or all of the listed index files above. Why would dovecot need to even enter cur/ if the index file is up to date? Is it verifying that the index file is up to date by re-reading some or all of the many files in cur/? If so, could it not get the info it needs by simply doing the equivalent of a ls, which would take considerably less time? The disk cache is only filled up an additional 30meg vs an additional 500meg from connection 1, so it's certainly not reading as much data. (also makes me wonder why the initial scan/index build could not use this lesser time consuming function if thats what it's doing). Additional information: Running strace on the initial indexing looks like this... ------------------------------------------- open("/var/spool/mail/test.visp.net/natetest/cur/1115929738.V902I67c13.test.visp.net:2,", O_RDONLY) = 8 fstat(8, {st_mode=S_IFREG|0600, st_size=4667, ...}) = 0 pread(8, "Return-Path: <mehl8nl3n8osm3r83a"..., 4096, 0) = 4096 pread(8, "zdik8dyrnffv6bbrue.itownshipno12"..., 4095, 4096) = 571 pread(8, "", 3524, 4667) = 0 close(8) = 0 open("/var/spool/mail/test.visp.net/natetest/cur/1115931742.V902I67c42.test.visp.net:2,", O_RDONLY) = 8 fstat(8, {st_mode=S_IFREG|0600, st_size=3881, ...}) = 0 pread(8, "Return-Path: <sender-5-8759012-9"..., 4096, 0) = 3881 pread(8, "", 215, 3881) = 0 close(8) = 0 ------------------------------------------- Running strace on the 3rd connection looks like this... ------------------------------------------- open("/var/spool/mail/test.visp.net/natetest/cur/1114490671.V902I6011f.test.visp.net:2,", O_RDONLY) = 10 fstat(10, {st_mode=S_IFREG|0600, st_size=5367, ...}) = 0 pread(10, "Return-Path: <qflfmq82vz8zg-u6ci"..., 4096, 0) = 4096 pread(10, "gs/rpoc_District6Spauldings.php?"..., 4095, 4096) = 1271 pread(10, "", 2824, 5367) = 0 close(10) = 0 open("/var/spool/mail/test.visp.net/natetest/cur/1114496568.V902I60bf5.test.visp.net:2,", O_RDONLY) = 10 fstat(10, {st_mode=S_IFREG|0600, st_size=2047, ...}) = 0 pread(10, "Return-Path: <removed(a)aaa-calif.c"..., 4096, 0) = 2047 pread(10, "", 2049, 2047) = 0 close(10) = 0 Thank you for the help! - Nate

[Dovecot] Problem with vpopmail auth

Hello, I've install 1.021 and am having some problems getting vpopmail authentication to work correctly (running 0.99 in production, upgrading to 1.021). I'm using vpopmail-5.4.16. Here are the authentication debug statements in the log, my dovecot.conf changes from default, and the schema of my vpopmail database. Any ideas / suggestions? I've commented out all authentication except for vpopmail. I took a look around the source but am not that familiar with the vpopmail api.

[Dovecot] LDAP auth_bind=yes in rc21 = goodness
by Adrian Close 06 Feb '07

06 Feb '07

Hi all, I finally got a chance to try out the fix for the LDAP auth_bind=yes issues in production (using rc21). It seems to be working just fine even after 24 hours of severe abuse. Incidentally, I had switched to bsdauth+login_ldap (on OpenBSD) which was often OK, but occasionally I would see Postfix smtpd throttled with SASL errors due to "connection refused" on the Dovecot authentication socket. This may just have been due to increased LDAP server load (Dovecot's internal LDAP generates much less). Thanks Timo! (And thanks Brad for updating the port) Adrian.

[Dovecot] minor kerberized dovecot build issue
by Dan Price 05 Feb '07

05 Feb '07

Hi all, again, I'm not knowledgeable about Kerberos, but we have a few users who use it to make sure that it works well on Solaris... so, they would like a Kerberized IMAPd. I tried compiling dovecot --with-gssapi on Solaris Nevada (the current development release), and the configure script choked for a couple of reasons. First, script uses 'grep -qv' in the case that you specify --with-gssapi to run some test. Unfortunately, Solaris doesn't have 'grep -q'. There's a note in GNU grep's manpage about this problem and a note that portable scripts should just redirect to /dev/null. Once I fixed this problem, I got: configure: WARNING: gssapi/gssapi.h: present but cannot be compiled configure: WARNING: gssapi/gssapi.h: check for missing prerequisite headers? configure: WARNING: gssapi/gssapi.h: see the Autoconf documentation configure: WARNING: gssapi/gssapi.h: section "Present But Cannot Be +Compiled" configure: WARNING: gssapi/gssapi.h: proceeding with the preprocessor's result configure: WARNING: gssapi/gssapi.h: in the future, the compiler will take +precedence configure: WARNING: ## ---------------------------------- ## configure: WARNING: ## Report this to dovecot(a)dovecot.org ## configure: WARNING: ## ---------------------------------- ## For whatever reason, on Solaris /usr/bin/krb5-config does not like the syntax 'krb5-config --cflags gssapi' (ditto with --libs). I found that removing the 'gssapi' part from the configure script fixed the problem, but I imagine this must break some other OS. If need be, I can follow up with the Kerberos team about this. Once I made these minor changes, I also had to add -lgss to the src/auth makefile's compile line. After that, I had no problem getting this to compile, although we have not yet tested it. -dp -- Daniel Price - Solaris Kernel Engineering - dp(a)eng.sun.com - blogs.sun.com/dp

[Dovecot] Problems enabling quota on MacOS X
by Lars Skovgaard 05 Feb '07

05 Feb '07

Hi, I'm trying to activate quotas for my users, preferably maildir++ quotas as all users are using maildir. I have compiled dovecot with quota-support, but when I try to enable quotas in the config, dovecot refuses to start up with a (to me, at least) strange message: Fopendir(/usr/local/lib/dovecot/imap) failed: No such file or directory Error: imap dump-capability process returned 89 In the logs I get the following: dovecot: read (imap dump-capability process) failed: Interrupted system call The directory "/usr/local/lib/dovecot/imap" is not missing, which would be the obvious explanation... Dovecot-version is 1.0rc21 (which by the way is running ***great*** without quotas). Thanks, /Lars

[Dovecot] Compile without GSSAPI disables SSL?
by Troy Engel 05 Feb '07

05 Feb '07

Perchance this is something unique to Red Hat -- I'm compiling/running 1.0rc?? on a CentOS 4 machine (i386), building RPMs and trimming down things I don't need (SQL e.g.). If I compile with the flag --with-gssapi, the resulting dovecot-auth binary links to libcrypto and libssl, the standard OpenSSL libs. Life is happy even though I don't need gssapi/krb5 support. If I remove --with-gssapi (but leave --with-ssl=openssl as before), the resulting dovecot-auth binary is no longer linked to the OpenSSL libraries (so I'm assuming no TLS/SSL support, but can't run the binary to test - I have SSL betatest users). So the question is, is this a ./configure problem in Dovecot, or some strangeness with Red Hat that you must link with gssapi/krb5 to get OpenSSL? Anyone care to hazard a guess? -te == details == The full configure line generated by the build is: + ./configure --build=i686-redhat-linux-gnu --host=i686-redhat-linux-gnu --target=i386-redhat-linux-gnu --program-prefix= --prefix=/usr --exec-prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin --sysconfdir=/etc --datadir=/usr/share --includedir=/usr/include --libdir=/usr/lib --libexecdir=/usr/libexec --localstatedir=/var --sharedstatedir=/usr/com --mandir=/usr/share/man --infodir=/usr/share/info 'INSTALL_DATA=install -c -p -m644' --with-doc --with-ssl=openssl --with-ssldir=/etc/pki/dovecot --with-ldap --with-gssapi --with-linux-quota=2 With gssapi: Install prefix ...................... : /usr File offsets ........................ : 64bit I/O loop method ..................... : poll File change notification method ..... : dnotify Building with SSL support ........... : yes (OpenSSL) Building with IPv6 support .......... : yes Building with pop3 server ........... : yes Building with mail delivery agent .. : yes Building with GSSAPI support ........ : yes Building with user database modules . : static prefetch passwd passwd-file checkpassword (modules) Building with password lookup modules : passwd passwd-file shadow pam checkpassword (modules) Building with SQL drivers ............: Without gssapi: Install prefix ...................... : /usr File offsets ........................ : 64bit I/O loop method ..................... : poll File change notification method ..... : dnotify Building with SSL support ........... : yes (OpenSSL) Building with IPv6 support .......... : yes Building with pop3 server ........... : yes Building with mail delivery agent .. : yes Building with GSSAPI support ........ : no Building with user database modules . : static prefetch passwd passwd-file checkpassword (modules) Building with password lookup modules : passwd passwd-file shadow pam checkpassword (modules) Building with SQL drivers ............: -- Troy Engel | Systems Engineer Fluid, Inc | http://www.fluid.com

Is there a way I can tell dovecot to only use the .subscriptions file, if it exists, as the source of mailfolder paths, rather than have it look at every file in a user's directory to see if it's a mail folder? I'm on RHEL4, still on dovecot dovecot-0.99.11 Thanks, Terry.

hi, (dovecot 1.0r15) I try to setup up two namespaces: 1- the first one (and default one) a maildir namespace 2- the second one a mbox namespace I want only one "INBOX", in the maildir namespace, no INBOX in the mbox namespace. I get what I want with this configuration: ---------------------------------------- mail_location = maildir:~/Maildir namespace private { inbox = yes } namespace private { separator = . prefix = mbox. location = mbox:~/mbox:INBOX= inbox = no hidden = no } ---------------------------------------- My question is: is it a normal way to do what I want ? I mean, the line location = mbox:~/mbox:INBOX= looks odd. I try with just the line inbox=no (without INBOX=) but dovecot set a default INBOX that disturbs some mail client. yours, -- David Bonnafous Institut de Mathématiques Université Paul Sabatier Toulouse - France

[Dovecot] Large & busy site, NFS with deliver only servers
by Dean Manners 05 Feb '07

05 Feb '07

Timo / Others, I have been working on a new installation for a fairly busy site, and after many weeks of tribulation have come to an architecture Im happy with: 2x Debian (2.6.18) - MXing machines running Postfix / MailScanner / Dovecot-LDA (A slightly patched RC17 for prettier Quota bounces) 2x Debian (2.6.18) - Mail retrieval machines running Dovecot IMAP/POP3 (Currently RC17) 3x Node Isilon NFS cluster (NetApp type devices) I chose Dovecot-LDA over Postfix-Virtual / Maildrop / Procmail due to its hassle free auto creation of new user maildirs, and the funkyness of built in Sieve functionality. The on the fly indexing sounded like a bonus at the time. However as Im sure all people who stress test with index's stored over NFS find, index locking makes for some 'spectacular crashes' (see others previous posts). I have tried out the recommended mount options and locking methods to no avail. Once under some stress, say ~60 messages a minute from the two front end machines, understandably the index's get pickled instantly. So as a hack way around the index locking problems, I have configured the MXing machines to index locally to no where (/tmp) - and deal with the very slightly slower IMAP/POP3 performance on the retrieval side. Is there way to tell/patch Dovecot-LDA not to bother with indexing? So Im not creating unused index files. Cheers __________________________________________ Dean Manners

[Dovecot] Quota crashing w/ gdb backtrace

Hi, I'm still running into consistent crashing when moving files between folders when dirsize quotas are enabled. This is running Dovecot1.0rc19.

However, the original files never gets deleted, so I assume that this crash is occuring during the deletion in the original folder. -- Dean Brooks dean(a)iglou.com

by Robert Schetterer 05 Feb '07

05 Feb '07

Hi all, ive just upgrade to rc21 ( so i dont know perhaps this report failure is fixed with this release ) i have reports from users that attachments get broken ( with rc19, dont know about before ) with some accounts , which where downloaded via a pop3 service to a exchange server, but in fact nothing is broken when looking with imap to the mailboxes Has anyone an idea, i havent any failure logs about that, is there a parameter which makes logging verbose to such failures? -- Mit freundlichen Gruessen Best Regards Robert Schetterer https://www.schetterer.org Munich/Bavaria/Germany -- Diese Nachricht wurde auf Viren und andere gefährliche Inhalte untersucht und ist - aktuelle Virenscanner vorausgesetzt - sauber.

[Dovecot] SSL error is it due to a self certified certificate?
by Matthew Bickerton 05 Feb '07

05 Feb '07

Hi I have set up dovecot with a self signed SSL certificate, created with the mkcert.sh script. Now I see the following in the log: pop3-login: SSL_accept() failed: error:14094416:SSL routines:SSL3_READ_BYTES:sslv3 alert certificate unknown [206.124.112.22] pop3-login: Disconnected: rip=206.124.112.22, lip=204.3.153.71, TLS handshake Is this caused by my self certified certificates. Or is it another problem? Thanks Matthew

[Dovecot] mail_log plugin, log throttling and killing of the IMAP child.
by Tan Shao Yi 05 Feb '07

05 Feb '07

Hi, Just a quick check, was wondering if anyone is experiencing problems mass deleting/purging mails from a folder? I am on RC19 with the mail_log plugin enabled. Quite often, when a mass deletion/purge is attempted, we receive the following message in the dovecot logs: dovecot: Feb 01 11:36:27 Error: IMAP(userid): Sending log messages too fast, throttling.. Sometimes this is accompanied by a message like the following and the user will be prompted with an error message saying that the connection has been abruptly terminated. dovecot: Feb 01 11:34:41 Error: child 3908 (imap) killed with signal 11 Is anyone experencing similar behaviour? Cheers, Tan Shao Yi

The following shows up in the "orphaned page" list of the Wiki: http://wiki.dovecot.org/MboxLocking?action=show&redirect=MboxSoftwareLocks Does the description of Dovecot mbox locking still apply to current versions? If yes, it should be linked from the "Troubleshooting" page. -- Jim Garrison (jhg(a)acm.org) PGP Keys at http://www.jhmg.net RSA 0x04B73B7F DH 0x70738D88

[Dovecot] unknown namespace with Mac OS client
by Francisco Reyes 05 Feb '07

05 Feb '07

I see in this thread, http://dovecot.org/list/dovecot/2006-April/012918.html, that others had simmilar problems with Mac OS client. Anyone got a working Dovecot + Mac OS setup? In particular with RC15. Our setup default_mail_env = maildir:Maildir namespace private { separator = . prefix = INBOX. inbox = yes } Would it help to use hidden = yes ?? Reading the description doesn't say much to me.. in particular I guess I am not familiar with the IMAP protocol to appreciate the explanation in the config file. The server is getting data originally coming from a Courier setup. I wrote a couple of scripts to convert files names and delete old setup files. So far we have moved 3 domains to this machine and the only one with the problem so far is the customer with the Mac client. Unless we can solve this soon, we will have to move him back to a courier server ... until we can figure how to solve this problem.

[Dovecot] Push IMAP
by Paul 05 Feb '07

Hearing that today's new Apple device is going to work with push IMAP from Yahoo, my first thought is to wonder whether an extension might make it possible for a Dovecot server to push its own IMAP in a compatible way. Paul

[Dovecot] command line options
by AJ Weber 05 Feb '07

05 Feb '07

Is the wiki up-to-date on the command-line arguments that can be passed to dovecot? I don't like the fact that I have to hard-code the "listen address" in the config file. Even though it shouldn't change (rarely if ever), when I have a multi-homed host, I need to specify only one of the interfaces. Would it be possible to either: 1) Make --listen into an optional, command-line argument; or 2) Make the listen config-file parameter understand interface names instead of just IP Addresses? (Like "eth0") -AJ

Timo, The gdb analysis is attached. It looks like memory got seriously stomped in this core dump. There was no assert or other useful information in the syslog. My setup: Solaris 9, imap and imaps, mbox format, INBOXes NFS mounted, index files on local ufs filesystem, beta8 configured like so: VERSION=1.0.beta8 CC=gcc CFLAGS="-g -O" CPPFLAGS=-I/opt/openssl/include LDFLAGS=-L/opt/openssl/lib \ ./configure --prefix=/opt/dovecot.$VERSION \ --with-ssl=openssl \ --with-ssldir=/opt/openssl/ssl \ --with-sql-drivers=no \ --disable-ipv6 \ > configure.out Jeff Earickson Colby College

[Dovecot] 1.0rc19 with plugins on AIX 5.2
by Ralf Becker 03 Feb '07

03 Feb '07

Hello, has anyone out there successfully build dovecot on AIX with plugins supported? I'm talking about an dlopen error when a plugin tries to access global symbols, that are defined in the dovecot "parent" binary For example: # MAIL_PLUGINS=zlib /usr/local/libexec/dovecot/imap imap(root): Error: dlopen(/usr/local/lib/dovecot/imap/lib20_zlib_plugin.so) failed: rtld: 0712-001 Symbol i_error was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol i_stream_get_data was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol i_stream_skip was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol i_stream_seek was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol i_stream_close was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol i_panic was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol pool_get_exp_grown_size was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found. Additional errors occurred but are not reported. Maybe libtool is the problem, because it does not export global symbols correctly. Or would a newer version of AIX vac fix this? Any ideas? I'm using dovecot 1.0rc19, AIX 5.2-06 and vac 5.0.2 Regards, Ralf -- ______________________________________________________________________ Dipl.-Inform.

[Dovecot] Automatic Folder Expiry (plugin?)
by Troy Engel 02 Feb '07

02 Feb '07

Greetings, I'm migrating an existing Courier IMAP installation to Dovecot (1.0rc19 right now) on a new server; there's one feature I'm not sure if Dovecot supports - but it might and I'm missing it, so I'll ask. In Courier there's an option to expire a folder after a given time period; ostensibly it's to keep a Trash folder clean, but we use it to keep the Junk folder (where spam is delivered by Exim) clean. How can I do this in Dovecot? Here's the chunk from Courier for those unfamiliar with it (just part of the verbiage): ##NAME: IMAP_EMPTYTRASH:0 # # The following setting is optional, and causes messages from the given # folder to be automatically deleted after the given number of days. # IMAP_EMPTYTRASH is a comma-separated list of folder:days. # # Important: the purging is controlled by CTIME, not MTIME ... So in our case it's set like so: IMAP_EMPTYTRASH=Junk:14 Thanks for any help/ideas - I'm not sure if we can live without this feature, the amount of spam is horrendous and users never clean out that folder. -te -- Troy Engel | Systems Engineer Fluid, Inc | http://www.fluid.com
