[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 … [View More]

[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

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 … [View More]"listen=" configurations, and checked lsof & tcpdump to rule out other problems, but it just seems as though dovecot isn't responding.

[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.

[Dovecot] migration question: "imap server directory"

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.

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.

[Dovecot] resilience suggestion

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 … [View More]

[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 … [View More]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 [View Less]

[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 … [View More]

[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 … [View More]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.

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 … [View More]

[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 … [View More]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.

[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 … [View More]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

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 .

[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 … [View More]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?

Hi, I've installed dovecot-imapd under ubuntu. My account and root are the only email accounts on my computer.

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.

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?

[Dovecot] Folders compat. problem ?

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.
