[Dovecot] I've moved to US
by Timo Sirainen 10 Feb '09

10 Feb '09

I thought about saying this in v1.2.beta1 release annoouncement, but looks like it'll take a few more days. So I've moved to Blacksburg, Virginia and I'm now working for Mailtrust the rest of this year. Here's some talk about it: http://mailtrust.com/blog (A bit stupid looking picture, but then again all my pictures seem to be that way so I didn't bother getting a new one taken.) And if it's not clear from that blog: Pretty much everything I do here will be Dovecot improvements that will be released as open source. Mailtrust has actually been paying for Dovecot features for about 3 years now.

[Dovecot] redelivered mail results in mail-forwarding-loop
by Reto Glauser 10 Feb '09

10 Feb '09

I try to redeliver mail for the following reason: Once in a while a user receives a mail which isn't correctly recognised as SPAM/HAM. He'll move the mail into a specific folder (say: retrain-as-spam/retrain-as-ham) and a script will retrain the mail. What I'd like to do is to redeliver the mail in order for correct (re)delivery (e.g. sieve scripts). Using sendmail to redeliver the mail I'm able to re-run the spam tests which will add it's SPAM headers and dovecot/sieve will be able to correctly file the message. I tried to just resend the mail: # /usr/sbin/sendmail -f foo@bar -v -oi foo@bar < mail but this results in a Diagnostic-Code: X-Postfix; delivery via dovecot: mail forwarding loop for foo@bar The problem is that the mail already has a "Delivered-To: foo@bar" line. The above is working when the "Delivered-To" line is being removed, and my question is if this can't be done automatically?

Hello, now I have done this: under http://wiki.dovecot.org/Logging?highlight=(logging) Rotating Logs is the following string ----------------------- /bin/kill -USR1 `cat /var/run/dovecot/master.pid 2>/dev/null` 2> /dev/null || true ------------------------ This string I have insert in /etc/logrotate.d/syslog under the lines: postrotate /bin/kill -HUP `cat /var/run/syslogd.pid 2> /dev/null` 2> /dev/null || true /bin/kill -HUP `cat /var/run/rsyslogd.pid 2> /dev/null` 2> /dev/null || true So Dovecot will be restarted, after the log rotates.

[Dovecot] Dovecot / Exim with Multiple Domiains
by Marc Perkel 10 Feb '09

10 Feb '09

I'm using a very old scheme for doing multiple domains using an old Linuxconf based setup. Each domain has it's own passwd/shadow file. It works but I need something new and modern and has a web interface and perhaps a mysql backend or something else good. So - what are people using out there for managing email users and domains? Thanks in advance.

Dovecot 1.1.8-0_85.el5 I'm seeing this set of messages repeat every 15 min. My best guess is the user tried to delete an imap folder and is failing?

[Dovecot] Authentication woes.

I'm still searching but hoping someone can offer a clue-stick. Long story short! I had a server crash suddenly and all I can get at are the files. Built a new host and copied the data and config files over, correcting ownership and permissions (hopefully) as I went. But now I can't get logged in. Messages in /var/log/dovecot/dovecot-info.log, without saslauthd running, are like this. dovecot: Feb 03 08:55:46 Info: auth(default): passwd-file(raanders(a)aesoft-sbcs.com,66.193.34.88): no passwd file: username_format=raanders /var/mail/vhosts/aesoft-sbcs.com/passwd dovecot: Feb 03 08:55:48 Info: auth(default): client out: FAIL 1 user=raanders(a)aesoft-sbcs.com dovecot: Feb 03 08:55:48 Info: auth(default): client in: AUTH 2 PLAIN service=IMAP secured lip=216.64.180.226 rip=66.193.34.88 resp=AHJhYW5kZXJzQGFlc29mdC1zYmNzLmNvbQBrNnpiZTQy dovecot: Feb 03 08:55:48 Info: auth(default): passwd-file(raanders(a)aesoft-sbcs.com,66.193.34.88): no passwd file: username_format=raanders /var/mail/vhosts/aesoft-sbcs.com/passwd dovecot: Feb 03 08:55:50 Info: auth(default): client out: FAIL 2 user=raanders(a)aesoft-sbcs.com dovecot: Feb 03 08:55:54 Info: imap-login: Aborted login: user=<raanders(a)aesoft-sbcs.com>, method=PLAIN, rip=66.193.34.88, lip=216.64.180.226, TLS The passwd file exists and I'm using the correct password. dovecot -n as an attachment.

[Dovecot] Dovecot 1.1.11 segfaults on auth configuration error
by Sebastian Kayser 10 Feb '09

10 Feb '09

Hi, i have compiled & packaged Dovecot 1.1.11 on Solaris 8 x86 with Sun Studio 11 and installed the result on Solaris 10 x86 zone. When i now configure auth mechanisms other than "login" or "plain" while only providing pam as the passdb, Dovecot segfaults on startup. I know that my configuration is wrong here, but i guess this still qualifies as a bug. Remedy would be appreciated. # /opt/csw/sbin/dovecot -F dovecot: Feb 06 22:56:24 Info: dovecot v1.1.11 starting up dovecot: Feb 06 22:56:25 Error: child 26870 (auth) returned error 89 (Fatal failure) Segmentation Fault (core dumped) # /opt/SUNWspro/bin/dbx -f /opt/csw/sbin/dovecot core (dbx) where =>[1] hash_lookup(table = (nil), key = 0x68f6), line 159 in "hash.c" [2] child_process_lookup(pid = 26870), line 31 in "child-process.c" [3] log_it(log_io = 0x80b8598, line = 0x80b7d4a "DIGEST-MD5 mechanism can't be supported with given passdbs", continues = 0), line 129 in "log.c" [4] log_write_pending(log_io = 0x80b8598), line 52 in "log.c" [5] log_read(log_io = 0x80b8598), line 191 in "log.c" [6] log_deinit(), line 331 in "log.c" [7] auth_process_destroy(p = 0x80b86f8), line 357 in "auth-process.c" [8] auth_process_input(process = 0x80b86f8), line 244 in "auth-process.c" [9] io_loop_handler_run(ioloop = 0x80b3518), line 204 in "ioloop-poll.c" [10] io_loop_run(ioloop = 0x80b3518), line 336 in "ioloop.c" [11] main(argc = 2, argv = 0x80478dc), line 599 in "main.c" # /opt/csw/sbin/dovecot -n # 1.1.11: /etc/opt/csw/dovecot/dovecot.conf # OS: SunOS 5.10 i86pc log_path: /dev/stderr login_dir: /var/opt/csw/run/dovecot/login login_executable: /opt/csw/libexec/dovecot/imap-login auth default: mechanisms: plain digest-md5 debug: yes passdb: driver: pam userdb: driver: passwd Please let me know in case there is any other information required to nail down the culprit.

[Dovecot] [patch] 'c' and 'd' in setacl
by Sascha Wilde 09 Feb '09

09 Feb '09

Hi Timo, Hi *, I just recognized that the new imap-acl plugin in dovecot 1.2 does not know the obsolete rights 'd' and 'c' when setting. According to RFC 4314 section 2.1.1.: If a client includes the "d" right in a rights list, then it MUST be treated as if the client had included every member of the "delete" right. and If a client includes the "c" right in a rights list, then it MUST be treated as if the client had included every member of the "create" right. Unfortunatly there are actually clients which depend on this behavior. I attached a rather rough[0] patch which implements this. cheers sascha [0] I don't like the use of static indexes witch imap_acl_letter_map but currently I wasn't able to decide on a more elegant solution. -- Sascha Wilde OpenPGP key: 4BB86568 http://www.intevation.de/~wilde/ http://www.intevation.de/ Intevation GmbH, Neuer Graben 17, 49074 Osnabrück; AG Osnabrück, HR B 18998 Geschäftsführer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner

[Dovecot] Rebuild folder listing?
by Roderick A. Anderson 09 Feb '09

09 Feb '09

I don't know what to call what I'm trying to do so I'll explain the situation. I had a total complete crash of the Linux-Vserver system that was hosting a Postfix+Dovecot guest with a three domains and 1-5 accounts per domain. Lots of mail though. Before it completely melted down I as able to get to the data (messages) and save them and the configuration files for both Dovecot and Postfix. I now have a replacement system up and running and have copied the directories onto it. I can log in to the accounts but I don't see the folders (I use Thunderbird as a MUA). Attempts to "subscribe" and "refresh" the list give me no results. No list of folders. What should I do? I'm thinking I could delete the dovecot files: dovecot.index, dovecot.index.cache, dovecot.index.log, dovecot-uidlist, subscriptions, and while I'm at it possibly dovecot-keywords. Then access the account(s) and Dovecot will rebuild them with the true/correct information. Am I heading anywhere near the right direction? TIA, Rod --

[Dovecot] Maildir structure question

The tmp directory is used during delivery, new messages arrive in new and read shall be moved to cur by the clients. " But in my Maildir, I see this: niko@petole:~$ ls -la Maildir/ total 144 drwxr-xr-x 35 niko niko 4096 2009-02-06 08:37 . drwxr-xr-x 25 niko niko 4096 2009-02-06 10:26 .. drwxr-xr-x 5 niko niko 4096 2009-02-06 09:16 .INBOX ...

[Dovecot] Best Imap Transfer Tool?
by Neil 08 Feb '09

08 Feb '09

So I'm looking to do a migration of my IMAP mailboxes, and I'm looking for the best tool to use. I used to use the uw-mailutil tool, a while ago, but that was a bit coarse of a tool. More recently I've used imapsync, but that was giving me some errors. I've sort of tracked those down; but I was wondering if anyone else had any other recommendations...? Thanks.

[Dovecot] Info regarding conversion of mbox to maildir
by Scott Silva 06 Feb '09

06 Feb '09

When I finally decide to convert to maildir, will I have to set up namespaces during the conversion, or will dovecot figure out where everything is by itself? Should I set up deliver to go to maildir/ globally, or per user? I have considered using the convert plugin, if there are not a lot of negatives. -- MailScanner is like deodorant...

[Dovecot] Public namespace permissions documentation/questions
by Thomas Hummel 06 Feb '09

06 Feb '09

Hello Timo, In my trials to setup a shared namespace with dovecot-1.1.8/LDAP passdb/userdb (prefetch)/Maildir, I found out that : 1) ACL are mandatory (at least if the acl plugin is triggered in dovecot.conf) Am I correct ? I'm still not sure if we can do without ACL at all (only with unix permissions and system_user userdb extra field). 2) the system_user userdb extra field is supposed to be ...the logname of the user the secondary groups of whom we want to check ! i.e. if user foobar belongs to secondary groups foogid, zgid, wgid and doveshared uid=xxx(foobar) gid=yyy(foogid) groups=zzz(zgid),www(wgid),vvv(doveshared) and we dovecot to take them into account, we have to make the usedb return the system_user extra field with the value foobar. Seems obvious now and said this way, but looking at the wiki : "system_user: If this is given, the user's groups are read from /etc/group (or wherever NSS is configured to taken them from)." I thought 'system_user' was a flag (a boolean) which, when triggered made dovecot look for the secondaries group of the user (user whose name is already known). a) am I correct ? b) why isn't system_user such a boolean ? Is there a case where we'd want system_user to be different than the user dovecot runs as at the moment the check takes place ? 3) same idea with acl_groups : since this extra_field holds a list of groups for the ACL plugin, why not rely on the native unix groups of the system the user belong to ? Thanks (and sorry for the 2 previous threads where I was blindly confused by the system_user thing). -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

Hello Timo, About the dovecot-shared file, the wiki says : "Unless you're using a single UID for all the users, you'll need to have a dovecot-shared file in each shared maildir. The group and the file permissions for new files inside the maildir are taken from the dovecot-shared file." but says the following too : "With Maildir dovecot-shared file controls if the \Seen flags are shared or private. If you don't have the file, they're shared." The question is "does it make sense (or is it even possible) not to have the file ?". Why would one not have the file and how would it work then ? By relying on the set-gid bit and umask ? Finally, the wiki says : "If you do have the file, the \Seen flag state is stored only in the user's index files. By making each user have their own private index files, you can make the \Seen flag private for the users." So, my undersanding is that : 1) you have the file 1.a) if INDEX points to the same place, flags are shared but are lost if indexes are lost 1.b) if INDEX points to some user dependant place, flags are private but are lost if indexes are lost 2) you don't have the file flags are shared, whatever INDEX points to and, since they're stored in filename, survive indexes lost. but does shared-mailboxes even work if we don't have that file ? maybe only if the set-gid bit and umask does what the file would have done ? So maybe, if you want to share flags, 2) is safer dans if you want them private, 1.b) is the only choice ? thanks -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] Shared subscription, acl-list and uidvalidity(s)
by Thomas Hummel 06 Feb '09

06 Feb '09

Hello, I'm running dovecot-1.1.8/Maildir/ACL plugin. I sucessfully set up a Maildir shared between users of the unix group 'doveshared' via a public namespace, unix permissions and ACL files. The location of my public namespace is /path/to/public. I tried 2 sub-setups : First setup ---------- drwxrws--- 4 root doveshared 4096 Jan 30 13:39 public -rw-r----- 1 root doveshared 18 Jan 30 13:38 public/subscriptions I first connect (in Thunderbird) to dovecot with user 'hummel', then with user 'doveimap'. The following files are created in /path/to/public/ : -rw------- 1 doveimap doveshared 40 Jan 30 14:03 dovecot-acl-list -rw------- 1 hummel doveshared 8 Jan 30 14:03 dovecot-uidvalidity -rw------- 1 hummel doveshared 0 Jan 30 14:02 dovecot-uidvalidity.4982fa7a I've got my own idea about what they're used for, but can you explain what they are supposed to be ? I guess the uidvalidity files are UIDVALIDITY, not for the mailboxes the namespace holds (since my understanding is that the uidvalidities of mailboxes are stored in the first line of dovecot-uidlist files), but for the namespace itself (in case it is destroyed and then recreated for instance). Am I right ? Why 2 files ? Second setup ------------- I follow the 'Shared subscriptions' section of the wiki : drw-r-s--- 4 root doveshared 4096 Jan 30 14:19 public -rw-r----- 1 root doveshared 18 Jan 30 13:38 public/subscriptions As expected, dovecot (and it shows in the logs), has not sufficient permissions to create the files above (dovecot-acl-list, dovecot-uidvalidity, dovecot-uidvalidity.4982fa7a). What are the consequences ? Thanks. -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] help: "dovecot: pipe() failed: Too many open files"
by Jake Grimmett 06 Feb '09

06 Feb '09

Dear All, I'm having an intermittent problem, with dovecot slowing to a crawl. Restarting dovecot fixes the problem. Looking at the maillog, I see loads of these errors.... dovecot: pipe() failed: Too many open files dovecot: Temporary failure in creating login processes, slowing down for now dovecot: Created login processes successfully, unstalling looking at the processes, I can see ~200 imap-login's and about ~700 imap's there are 1000 email accounts on the server - half of which are in regular use. The server is Dell PE1950 running dovecot (1.0.7-2.el5) as supplied with Centos 5.2 (~Redhat AS 5.2) in 64 bit mode. I've upgraded the server from 4 to 8GB of RAM, and from a dual core 1.5Ghz xeon, to a quad core 1.5GHz xeon, and this does not seem to help. The following settings were increased by me to try and stop this problem - but did not have an obvious effect: login_process_size = 128 login_process_per_connection = yes login_max_processes_count = 512 Other parameters were left commented out: #max_mail_processes = 1024 #auth_process_size = 256 If anyone has any ideas about where I might be going wrong, please let me know..! many thanks Jake -- Dr Jake Grimmett Head Of Scientific Computing MRC Laboratory of Molecular Biology Hills Road, Cambridge, CB2 0QH, UK.

[Dovecot] NFS - inotify vs kqueue
by Jack Stewart 06 Feb '09

06 Feb '09

Hi, I've seen some chatter on NFS boards about kqueue being more reliable than inotify when used in NFSv3 and NFSv2. The chatter is a bit old so I don't know if it is true anymore. Anyone have pro/con experience with dovecot on the inotify/kqueue question when using NFS storage? I realize that kqueue is probably a bit slower and causes some delay with IDLE. Also, it may not really make any difference which is why I ask the question. ---Jack

[Dovecot] Hi all,
by Jehan Pagès 06 Feb '09

06 Feb '09

Hi all, as I told earlier, I am installing an email server with postfix/dovecot/dspam (for now that's all, though some programs may come later). For now, what works good enough is that I receive mails and spams are tagged. Dovecot version 1.1.7-r1 compiled from the gentoo depository with debug. The path of a mail is 1/ to be passed to dspam by postfix as a virtual transport with this in master.cf: dspam unix - n n - - pipe flags=DRhu user=vmail argv=/usr/bin/dspam --client --deliver=innocent,spam --user ${recipient} and this in main.cf: virtual_transport = dspam 2/ Then in dspam.conf, I have: TrustedDeliveryAgent "/usr/libexec/dovecot/deliver -d %u" UntrustedDeliveryAgent "/usr/libexec/dovecot/deliver -d %u" QuarantineAgent "/usr/libexec/dovecot/deliver -d %u -m Junk" Now dspam is tagging a lot of my spams, with [SPAM] on the subject and in the header stuffs like this: X-DSPAM-Result: Spam X-DSPAM-Processed: Thu Feb 5 23:49:02 2009 X-DSPAM-Confidence: 0.5232 X-DSPAM-Probability: 0.9869 X-DSPAM-Signature: 498b6cde61901804284693 X-DSPAM-Factors: 27, Subject*watch, 0.99000, a+loved, 0.99000, Subject*for+all, 0.99000, ... ... But I wanted spam to go in my Junk folder (using maildir, this is the directory .maildir/.Junk for my configuration. Hence the above configuration of QuarantineAgent. But it doesn't work as my emails are still deliverd to INBOX. How could I check that dovecot deliver is taking into account the option "-m Junk"? Or maybe I don't use it well? (I tried also "-m .Junk" as it it the name of the directory but it is the same) Note also that I use maildir format, so maybe this option works only with mailbox? The doc says: -m <mailbox>: Destination mailbox (default is INBOX). In my dovecot.conf, I have: protocol lda { hostname = mydomain.tld log_path = /home/vmail/dovecot-deliver.log info_log_path = /home/vmail/dovecot-deliver.log auth_socket_path = /var/run/dovecot/auth-master } And when a deliver occures, that's all I have in dovecot-deliver.log: deliver(recipient(a)mydomain.tld): Feb 06 00:59:47 Info: auth input: recipient(a)mydomain.tld deliver(recipient(a)mydomain.tld): Feb 06 00:59:47 Info: auth input: home=/home/vmail/mydomain.tld/recipient/ deliver(recipient(a)mydomain.tld): Feb 06 00:59:47 Info: auth input: uid=1004 deliver(recipient(a)mydomain.tld): Feb 06 00:59:47 Info: auth input: gid=1004 deliver(recipient(a)mydomain.tld): Feb 06 00:59:47 Info: maildir: data=/home/vmail/mydomain.tld/recipient/.maildir deliver(recipient(a)mydomain.tld): Feb 06 00:59:47 Info: maildir++: root=/home/vmail/mydomain.tld/recipient/.maildir, index=, control=, inbox= =/home/vmail/mydomain.tld/recipient/.maildir deliver(recipient(a)mydomain.tld): Feb 06 00:59:47 Warning: Growing pool 'Cache fields' with: 2048 deliver(recipient(a)mydomain.tld): Feb 06 00:59:47 Info: msgid=<000d01c987ed$879c82f0$6400a8c0@biancauj3>: saved mail to INBOX Is there a way to check the options set on parameters in the logs, so that I check that dspam runs indeed QuarantineAgent? Or would you have other solution/hints? Someone on the dspam ml told me that maildrop or sieve are more flexible. So I explain here that my "reason" was simply that I thought it would be better not to install another software/component to remain simple. Moreover with the "-m" option, dovecot-deliver seemed to do just what I needed (I don't need much more complicated). But maybe I am wrong or it is really better not to use dovecot-deliver. If so, just tell me. Thanks. Jehan

[Dovecot] Expire plugin does not work
by Nicolas Letellier 06 Feb '09

06 Feb '09

Hi. I test expire plugin for my dovecot 1.1.8. But, it seems to not work. I have 3 mailboxes on my machine. I want my messages in Junk and Trash expire after 1 day. I removed all messages in them before installing expire plugin. See my dovecot.conf: expire: Trash 1 Junk 1 expire_dict: proxy::expire My dabatases in /var/lib/dovecot are used. When I launch /usr/local/sbin/dovecot --exec-mail ext /usr/local/libexec/dovecot/expire-tool --test, it says: Info: user3(a)domain.tld/Trash: stop, expire time in future: Wed Feb 4 21:00:50 2009 Why this message? I have 3 mailboxes, and the message appears only with this mailbox. The 2 others mailbox have mails into Trash and Junk folders. And the mail are older than 2 days. An ls -lcs say it. When I launch /usr/local/sbin/dovecot --exec-mail ext /usr/local/libexec/dovecot/expire-tool, no messages appears. Nothing in my dovecot logs. Nothing (and I set mail_debug). No messages are deleted. In a mailbox1, I have this into Junk/cur directory: 4 -rw------- 1 dovecot dovecot 3822 Feb 2 13:39 1233569469.M275631P48216.***.***.net,S=3822,W=3945:2,S 4 -rw------- 1 dovecot dovecot 3004 Feb 2 15:43 1233585799.M730005P46882.***.***.net,W=3078,S=3004:2,S 4 -rw------- 1 dovecot dovecot 3056 Feb 2 17:49 1233587786.M676156P51401.***.***.net,S=3056,W=3132:2,S 4 -rw------- 1 dovecot dovecot 3732 Feb 2 17:49 1233592892.M701994P52459.***.***.net,S=3732,W=3823:2,S We are Feb 4, and these message are always here.

[Dovecot] ¿DC won't start? "leaked file fd 5:"

Hi Gents, (apologizes, new here...) I didn't find any hint on G**gle nor in the Dovecot archieve (maybe due to the lack of a search function :), so: I installed Doovecot, but can't get it going. The logfile states: > mail.info dovecot: Dovecot v1.0.15 starting up > mail.err dovecot: auth(default): Panic: Leaked file fd 5: dev 0.10 inode 3 > mail.err dovecot: Auth process died too early - shutting down I tried many obscure things to recover, but had no luck so far. As long i am just guessing around (auth? dev 0.10?? maybe SSL config?), i have no clue what happens here :(. To make things more interesting: the installation lives on an embedded device (xscale, aka arm w/4MB RAM), where are no extended debug features available (like ltrace, ldd,...), and no newer packages (if exist) available. Tried so far: * uninstall (ipkg remove) * rm'd all files listed in the package description + /var/run/dc/* * reinstall (ipkg install) * changed the config file (in many ways... but what??) The init-script does mainly "/opt/sbin/dovecot", so i tried that command on the CLI(bash) to be sure no script mangles fd's around. "echo $?" gives "0" then, but no DC process is running- log messages as above. I have no clue what to do abt that- where's the point?? Can this hopefully be done whithout installing the complete gcc toolchain and compiling a newer version from source, but by just adapting the config? 8-| Any helpful hints appreciated!, acend -- -- Psssst!

[Dovecot] Dovecot performance on GFS clustered filesystem
by Allen Belletti 06 Feb '09

06 Feb '09

Hello All, We are using Dovecot 1.1.3 to serve IMAP on a pair of clustered Postfix servers which share a fiber array via the GFS clustered filesystem. This all works very well for the most part, with the exception that certain operations are so inefficient on GFS that they generate significant I/O load and hurt performance. We are using the Maildir format on disk. We're also using Dovecot's deliver from Postfix to handle local delivery. As best I can determine, the worst problems occur when certain users with very large Inboxes (~10k messages) receive new mail and their client looks up information about that message. GFS doesn't seem to efficiently handle the large directories that contain folders like this. As a result, lots of I/O ops are generated and performance suffers for everyone. I am beginning to wonder if it might be more efficient to revert to the old mbox format, with one file per folder (plus whatever indices are creates.) It seems that this ought to work better with GFS which is geared toward smaller numbers of larger files. Is anyone on the list currently doing that? Alternately, any thoughts regarding tuning or other options would be appreciated.

[Dovecot] The 'dbox' Format
by Alexander Beisig 06 Feb '09

06 Feb '09

I'd like to give the dbox format a try, but I could not find any information on how to enable it. There's information on how to set mail_location for the Maildir and mbox formats in the wiki and also in the commented configuration file, but how to set it for dbox is strangely missing. I took a guess with 'mail_location = dbox:~/dbox', but that didn't work, so it's probably not the right way. Also, the version of Dovecot that Debian installed was 1.0.15, which is kinda old. Should there any serious reasons why I should manually install a newer version if I'm going to use dbox? __________________________________________________________________ Deutschlands größte Online-Videothek schenkt Ihnen 12.000 Videos!* http://entertainment.web.de/de/entertainment/maxdome/index.html

[Dovecot] Deferred emails on alias emails
by Jehan Pagès 05 Feb '09

05 Feb '09

Hi, I am currently making a fresh install of email server. I am having some issue with dovecot-antispam (cf. other emails), and noticed that I was having issues on aliases, which apparently where not forwarded to the actual SMTP server after passing through dspam. Still don't figure why but temporarily disable the dspam filter, which anyway is not useful in the current state of this installation. Now the email to an alias are well forwarded to the real finale server. But I still have many emails which were deferred in the last days and I cannot have them decrease. # ls -l /var/spool/postfix/defer/* | wc -l 297 If I run "postqueue -f" to flush this all, I can see the number down, but fastly comes back to 297. Reading the logs, they are passed to dovecot, which was probably the issue before I disabled dspam. It was trying to deliver a message after filtering it, but in the case of aliases, of course, it cannot because the account is not local (so it does not find the account and defers the email forever)! So it should give it back to postfix so that this one contacts the aliased server (gmail.com in the example below). Feb 4 13:33:18 ks34186 postfix/lmtp[31100]: 82769869FA: to=< someemail(a)gmail.com>, orig to=<someemail(a)mydomain.tld>, relay=mail.mydomain.tld[/var/run/dspam/dspam.sock] conn use=28, delay=142296, delays=142277/19/0/0.41, dsn=4.3.0, status=deferred (host mail.mydomain.tld[/var/run/dspam/dspam.sock] said: 421 4.3.0 <someemail(a)gmail.com> Auto-Whitelisted (in reply to end of DATA command)) Feb 4 13:33:18 ks34186 dovecot: auth(default): master in: USER 1 someemail(a)gmail.com service=deliver Feb 4 13:33:18 ks34186 dovecot: auth(default): passwd(someemail(a)gmail.com): lookup Feb 4 13:33:18 ks34186 dovecot: auth(default): passwd(someemail(a)gmail.com): unknown user Feb 4 13:33:18 ks34186 dovecot: auth-worker(default): sql( someemail(a)gmail.com) SELECT maildir as home, 1004 as uid, 1004 as gid FROM mailbox WHERE username = 'someemail(a)gmail.com' AND active = '1' Feb 4 13:33:18 ks34186 dovecot: auth-worker(default): sql( someemail(a)gmail.com) Unknown user Feb 4 13:33:18 ks34186 dovecot: auth(default): master out: NOTFOUND 1 So is there a way please to flush this whole spool so that it now uses the new method (which is stop using dspam until I figure how to use it) and so that I can forward these emails to their recipient? Thanks. Jehan P.S.: this is maybe more a postfix issue than a dovecot issue though... but you probably all know well postfix as well.

[Dovecot] Script: Moving Maildirs between servers
by Peter Lindgren 05 Feb '09

05 Feb '09

Hi, I just migrated from dovecot 1.0.rc29 to 1.1.7, from Sparc platform to Intel, it went very well. In the process I merged folders and excluded folders from being copied. User rights on folders were kept/set. I thought I'd share my migration script with you folks. If there's an interest to put it on the wiki I can do that, but I'm not sure in what page. Use it as a starter if you need to do this yourselves. Prerequisites: * User names are local unix accounts * Old server's /home must be mounted with nfs * Structure and user names must match between the two systems * Source dovecot must be at least version 1.0.x * Destination dovecot must be 1.1.x * Only dovecot data folders and files are copied, neither dovecot indices nor Sieve scripts etc. Here it goes, have fun! /Peter #!/bin/sh # # Migrates dovecot Maildir folders and settings from older dovecot on # old server to new dovecot on new server. # Prerequisites: # * User names are local unix accounts # * Old server's /home must be mounted with nfs # * Structure and user names must match between the two systems # * Source dovecot must be at least version 1.0.x # * Destination dovecot must be 1.1.x # * Only dovecot data folders and files are copied, neither dovecot indices nor Sieve scripts etc. # # Originally created by Peter Lindgren <peter(a)norrskenkonsult.com> # Use this script at your own risk.

[Dovecot] pop3_lock_session question
by Mark Costlow 04 Feb '09

04 Feb '09

Hello, I'm preparing to convert from qpopper + UW-IMAP to dovecot. So far testing has gone very well. One problem we haven't figured out is that long-running POP sessions keep the mailbox locked, so that the MDA times out while trying to deliver. We're using "maildrop" as our MDA if that matters. We don't see this issue for dovecot IMAP sessions. During long-running IMAP sessions, incoming messages are deilvered tot he user's INBOX without delay. But with POP, the MDA times out and the messages go back to sendmail's queue for later delivery. We though this setting would address the issue: # Keep the mailbox locked for the entire POP3 session. pop3_lock_session = no But it doesn't seem to. Any ideas? Here is our "dovecot -n": ---------------------------------------------------------------------- # 1.1.8: /usr/local/etc/dovecot.conf # OS: FreeBSD 7.1-RELEASE-p2 i386 base_dir: /var/run/dovecot/ protocols: imap imaps pop3 pop3s ssl_cert_file: /etc/mail/certs/mail.swcp.com.pem ssl_key_file: /etc/mail/certs/mail.swcp.com.pem ssl_cipher_list: ALL:!LOW:!SSLv2 disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no verbose_proctitle: yes first_valid_uid: 1000 first_valid_gid: 100 mail_privileged_group: mail mail_location: mbox:~/:INBOX=/var/mail/%u:INDEX=/var/dovecot/%u mail_full_filesystem_access: yes mmap_disable: yes mail_nfs_storage: yes mail_nfs_index: yes lock_method: dotlock mbox_lock_timeout: 120 dbox_rotate_days: 0 mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 imap_client_workarounds(default): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): pop3_reuse_xuidl(default): no pop3_reuse_xuidl(imap): no pop3_reuse_xuidl(pop3): yes pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login username_format: %Lu winbind_helper_path: /usr/local/bin/ntlm_auth verbose: yes debug: yes debug_passwords: yes passdb: driver: pam args: session=yes dovecot userdb: driver: passwd args: blocking=yes socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 master: path: /var/run/dovecot/auth-master mode: 384 ---------------------------------------------------------------------- Thank, Mark -- Mark Costlow | Southwest Cyberport | Fax: +1-505-232-7975 cheeks(a)swcp.com | Web: www.swcp.com | Voice: +1-505-232-7992 abq-strange.com -- Interesting photos taken in Albuquerque, NM Last post: Cruising San Mateo I - 2009-01-04 15:20:30

[Dovecot] Starting using LaunchDaemons
by Bruce Bodger 04 Feb '09

04 Feb '09

I've figured this one out... Just wanted to get it into the dovecot mailing list archive so that somebody in the future might find it if they need it. Running Dovecot on Mac OS X 10.4.11 and using LaunchDaemon to start. Following a system crash, dovecot failed to restart with this in the system log... Feb 4 10:04:29 G520X2 launchd: org.dovecot: exited with exit code: 89 Feb 4 10:04:29 G520X2 launchd: org.dovecot: respawning too quickly! throttling Feb 4 10:04:29 G520X2 launchd: org.dovecot: 7 more failures without living at least 60 seconds will cause job removal Feb 4 10:04:29 G520X2 launchd: org.dovecot: will restart in 10 seconds Feb 4 10:04:39 G520X2 launchd: org.dovecot: exited with exit code: 89 Feb 4 10:04:39 G520X2 launchd: org.dovecot: respawning too quickly! throttling Feb 4 10:04:39 G520X2 launchd: org.dovecot: 6 more failures without living at least 60 seconds will cause job removal Feb 4 10:04:39 G520X2 launchd: org.dovecot: will restart in 10 seconds Feb 4 10:04:49 G520X2 launchd: org.dovecot: exited with exit code: 89 Feb 4 10:04:49 G520X2 launchd: org.dovecot: respawning too quickly! throttling Feb 4 10:04:49 G520X2 launchd: org.dovecot: 5 more failures without living at least 60 seconds will cause job removal Feb 4 10:04:49 G520X2 launchd: org.dovecot: will restart in 10 seconds The problem turned out to be an old master.pid file (/usr/local/var/ run/dovecot/master.pid) that was left over from the crash. Deleting the file allowed dovecot to restart. Actually, dovecot told me what the problem was when I attempted to start it from the command line as opposed to starting it with the LaunchDaemon... G520X2:root# /usr/local/sbin/dovecot -F Fatal: Dovecot is already running with PID 59 (read from /usr/local/ var/run/dovecot/master.pid) Hope it helps someone else. B. Bodger

[Dovecot] auth_debug_passwords
by Josh Gentry 04 Feb '09

04 Feb '09

Hi. I'm new to Dovecot and about to start using it in production. In the config file, I set the option, auth_debug_passwords, to yes. I do not see any failed passwords logged, however. It did cause more verbose authentication logging, but failed passwords are still hidden. I have also set these options to yes, because I thought they might be required for auth_debug_passwords to work: auth_verbose = yes auth_debug = yes Here's an example of what I see with a failed login: Feb 3 17:03:36 ebi5 dovecot: auth-worker(default): pam(jkd,some IP): lookup service=dovecot Feb 3 17:03:36 ebi5 dovecot: auth-worker(default): pam(jkd,some IP): #1/1 style=1 msg=Password: Feb 3 17:03:36 ebi5 dovecot: auth-worker(default): pam(jkd,some IP): pam_authenticate() failed: authentication error (password mismatch?)

I was using the RoundCube web client on my server and had no such message. It was just telling me that it could not move the message. I configured a Thunderbird then and it displayed indeed this message 'Failed to call dspam'. So I made your trick, I compiled myself the dovecot-antispam library and now I can move messages... But are you sure that it is the right method and that the dspam training is indeed called? Because if I read well this piece of code, it looks like it was checking if the dspam training was successful. We commented out this check, so now maybe it fails and we copy the messages anyway to Junk/ even though no training really occurred. And when I check the logs or the dspam_stats, I don't see any change, even though I guess this retraining should be seen as a change in the stats, no? > > Antispam plugin is easy to understand: when you configure antispam_spam > = SPAM it will set SPAM folder as his special folder to observe.

By the way, when one has the item "X-DSPAM-Result: Innocent" in the header, it means the email is not a spam, does'nt it (right now I am focusing on having this plugin working for training purpose, but currently not much is working perfectly as expected in my email spam system)? > > You can provide some info from your log files, i'll try to help.

[Dovecot] Dovecot on Mac - Entourage cannot fetch emails
by Bijo 03 Feb '09

03 Feb '09

Hi, Dovecot 1.1.3 is running on Mac OS X 10.5 latest version, with Maildir (LAYOUT=fs). I have following issues when Entourage 2008 connects it, over imap/imaps. Entourage does not cache the mails. After every restart the folder contents are fetched fresh. I have enabled the Entourage option to get entire messages. Entourage caches the gmail IMAP folders fine. Also Outlook 2007 does not have this problem while connecting to the same IMAP server. I have some big folders with a few thousands of emails. Entourage fails with Error: 4362 (Mail could not be retrieved this time) while fetching mails from these folders. Restarting and rebuilding the Entourage database did not fix this issue. Any tips to resolve these issues or to debug what is going on would be greatly appreciated. Thanks, Bijoy -- View this message in context: http://www.nabble.com/Dovecot-on-Mac---Entourage-cannot-fetch-emails-tp2175… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Dovecot 1.1.10 and chroot
by Michal Soltys 03 Feb '09

03 Feb '09

As it's been a while since I upgraded (1.1rc10, jump to 1.1.10), this might be present in earlier versions as well. Anyway, if one enables mail_chroot in global config file, dovecot will try to access /tmp there. Per-user overrides behave correctly. For example, with: mail_chroot=/home/vmail dovecot will abort with: Fatal: chdir(/home/vmail/tmp) failed with uid 65534: No such file or directory Error: imap dump-capability process returned 89 Fatal: Invalid configuration in /etc/dovecot.conf

[Dovecot] Dovecot-antispam does not work
by Jehan Pagès 03 Feb '09

03 Feb '09

Hi, I have installed dovecot-antispam and configured it this way (as in the doc) with the dspam exe: protocol imap { mail_plugins = antispam mail_plugin_dir = /usr/lib64/dovecot/imap } plugin { # For dovecot-antispam: antispam_signature = X-DSPAM-Signature antispam_trash = trash;Trash;Deleted Items antispam_spam = SPAM;Junk #antispam_unsure = unsure antispam_dspam_binary = /usr/bin/dspam antispam_dspam_args = --deliver=;--user;%u antispam_mail_tmpdir = /tmp } But it does not work and really I cannot figure it out for two days, because I can find no log wherever, where it writes it does (or try to do) something, nor in the dovecot logs, nor in the dspam logs. But I know something is happening because when I try to move a spam from my inbox to the Junk folder, it fails with an error telling it could not move the email. At the opposite, when I deactivate the antispam plugin, I can move normally the emails. So what could I do to fix my issue or at least diagnose it (where would I find logs of what is happening?)? Thanks. Jehan

[Dovecot] Mail undeliverable error
by jan gestre 03 Feb '09

Hi Guys, I've already posted this to the postfix mailing list and they made sure the error as the title suggest was generated by dovecot and not the other way around. I have an almost perfectly working multi domain mail server running dovecot+postfix+mysql+postfixadmin behind pfsense, when we transferred office, issues arose, suddenly users using email clients like thunderbird/outlook suddenly can't send mail when outside the office and instead gets an smtp denied or worst a mail undeliverable error. The mail undeliverable error was that the postmaster user is unknown yet I've created the alias using postfixadmin. I've made repeated test and sent mail directly to the postmaster and the email was received by the intended user, I'm stumped and have no idea to fix this. Hope you can help me, TIA. Here's the output of dovecot -n: dovecot -n # /etc/dovecot.conf base_dir: /var/run/dovecot/ log_timestamp: %Y-%m-%d %H:%M:%S ssl_cert_file: /etc/postfix/ssl/mail-cert.pem ssl_key_file: /etc/postfix/ssl/mail-key.pem login_dir: /var/run/dovecot//login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login first_valid_uid: 150 last_valid_uid: 150 mail_extra_groups: mail mail_location: maildir:/home/virtualmail/%d/%u maildir_copy_with_hardlinks: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login digest-md5 user: nobody passdb: driver: sql args: /etc/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot-sql.conf socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 user: postfix group: mail master: path: /var/run/dovecot/auth-master mode: 432 user: virtualmail group: mail
