[Dovecot] Wiki to doc/ in tarball
by Timo Sirainen 16 Feb '07

16 Feb '07

So I finally started building a script that does it. Anyone interested in helping with it so that it produces readable output? First step is getting raw wiki pages. I'll do this directly by getting them from the filesystem. You can get them from here: http://dovecot.org/tmp/wikipages.tar.gz Next there's http://dovecot.org/tmp/wiki2txt.pl which is my horrible Perl script that kind of works now to produce almost readable text files. Its current output is in http://dovecot.org/tmp/wikitxt.tar.gz One thing I'm wondering about is how to make the directory layout work. For example there is "UserDatabase" and "UserDatabase/Static" pages. Currently I'm placing the latter into "_UserDatabase/Static" but I don't think that's the best solution. I was thinking about adding some "include" and "exclude" lists. If a page is in excluce list it's skipped. If it's in neither list it prints a warning but still includes it. So this makes it easy to find out the new pages and figure out if they should be included in the documentation.

[Dovecot] Index Prob
by Kevin Richter 16 Feb '07

16 Feb '07

Hi, i have a problem with rc19 (sorry, i have no time at the moment to uptime) and homedirs and maildirs mounted via NFS on Solaris10. At the beginning of the following log file everything is ok. At the end it cannot access the index... and just deleted the whole mailbox! It was empty... so it was no problem. Any ideas? Thanks.

[Dovecot] Son't have IMAPS

Hi, I've installed dovecot and i'm pretty sure it has SSL support built in. But i don't have IMAPS. I get all sort of errors. Thunderbird tells: "The connection was refused".

[Dovecot] Is it 1.0 yet?
by Marc Perkel 15 Feb '07

15 Feb '07

OK - my last main bug was fixed a few releases ago. I know that there's no end to getting things right but there comes a point when you need to call it done. No one trusts a 1.0 to be perfect but Dovecot is already better that most 2.0 versions of other software. I vote (as if my vote counted) to call it done, declare victory, and move on to 1.01, 1.02 etc. No one is going to trus it till it gets to 1.02 so I say lets bless it and move on.

[Dovecot] 1.0.rc22 released
by Timo Sirainen 15 Feb '07

15 Feb '07

http://dovecot.org/releases/dovecot-1.0.rc22.tar.gz http://dovecot.org/releases/dovecot-1.0.rc22.tar.gz.sig Found another bad bug in rc19 changes. Wonder why my imaptest catched the bug only in CVS HEAD but not in branch_1_0 even though both had it. Anyway, now the imaptest runs nicely for both, and I'm again optimistic that the bug count is low enough for v1.0 to be released soon :) BTW. My previous benchmarks which showed how mmap_disable=yes and fsync_disable=yes give huge performance benefits are pretty XFS-specific. I did some quick tests with ext3 and the differences were quite small with it. I'll probably do another proper run of tests later. + pop3: Commit the transaction even if client didn't QUIT so cached data gets saved. - Fixed another indexing bug in rc19 and later which caused transactions to be skipped in some situations, causing all kinds of problems. - mail_log_max_lines_per_sec was a bit broken and caused crashes with dovecot -a - BSD filesystem quota was counted wrong. Patch by Manuel Bouyer - LIST: If namespace has a prefix and inbox=no, don't list prefix.inbox if it happens to exist when listing for %.

>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).

[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.

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.

[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
by lenny＠edpausa.com 15 Feb '07

15 Feb '07

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
by Nicolas Boullis 15 Feb '07

15 Feb '07

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

[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.

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

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. But this is prevented from working since it insists on resetting back to the user's primary group. Thanks, Sam Hathaway The relevent section of my dovecot.conf looks like this: protocol lda { postmaster_address = postmaster(a)uofr.net log_path = /var/log/dovecot-lda.log } auth default { mechanisms = plain socket listen { master { path = /var/run/dovecot-auth-master mode = 0660 group = mail } } # ... (other auth config directives here) } And the relevent parts of my exim4.conf are as follows: # in router section: local_user: debug_print = "R: local_user for $local_part@$domain" driver = accept domains = +local_domains check_local_user local_part_suffix = +* local_part_suffix_optional local_parts = ! root transport = dovecot_deliver_user # in transport section: dovecot_deliver_user: debug_print = "T: pipe for $local_part@$domain" driver = pipe command = /usr/lib/dovecot/deliver -d $local_part message_prefix = message_suffix = log_output delivery_date_add envelope_to_add return_path_add group = mail Here are the permissions on some interesting files/dirs: -rwxr-xr-x 1 root mail 551424 2006-11-22 21:59 /usr/lib/dovecot/deliver drwxrwsr-t 2 root mail 1024 2007-01-25 14:14 /var/mail -rw-rw---- 1 sam-adm mail 544 2007-01-25 15:58 /var/mail/sam-adm srw-rw---- 1 root mail 0 2007-01-25 15:39 /var/run/dovecot-auth-master And here's how I've been testing: echo "test" | mail -s "deliver test" sam-adm When I execute the above command, exim says: 2007-01-25 15:55:01 1HABcb-0006h4-N8 <= sam-adm(a)vps.uofr.net U=sam-adm P=local S=334 2007-01-25 15:55:02 1HABcb-0006h4-N8 ** sam-adm(a)vps.uofr.net R=local_user T=dovecot_deliver_user: Child process of dovecot_deliver_user transport returned 89 from command: /usr/lib/dovecot/deliver 2007-01-25 15:55:02 1HABcb-0006h4-N8 Completed And deliver says: deliver: "2007-01-25 15:55:02 "Fatal: setgid(10000) failed: Operation not permitted

[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
