[Dovecot] Don't let deliver create index files
by Martin Strand 09 Sep '07

09 Sep '07

For various reasons I want to use deliver with Postfix and Courier-IMAP, and it seems to work fine except for one thing: deliver creates some dovecot.* index files that Courier never uses (and I assume deliver doesn't need them) Is there a way to prevent that? Thanks, Martin

[Dovecot] Using NID_x500UniqueIdentifier as ssl_username_from_cert
by S. Wefel 09 Sep '07

09 Sep '07

Hi, please have a look at the attached patch for dovecot-1.0.3 These patch modifies ssl_proxy_get_peer_name() to use the NID_x500UniqueIdentifier as username instead of NID_commonName. The reason is, that the Common Name doesn't have to be unique for the whole mailserver. Example; in germany a lot of people got the first name "Andreas" and the last name "Schulz". Therefore a lot of certificates exists with subjects like this: C=DE,O=ABC,CN=Andreas Schulz/emailAddress=andreas.schulz(a)abc.de C=DE,O=DEF,CN=Andreas Schulz/emailAddress=andreas.schulz(a)def.de ... dovecot couldn't distinguish between these users. So we decide to use certificates with an X509v3 extension NID_x500UniqueIdentifier which allows to extend the subject by an unique ID, e.g. the unix-uid or a database unique key. The new certificates may look like this: C=DE,O=ABC,CN=Andreas Schulz/emailAddress=andreas.schulz(a)abc.de/x500UniqueIdentifier=user1 C=DE,O=DEF,CN=Andreas Schulz/emailAddress=andreas.schulz(a)def.de/x500UniqueIdentifier=user2 With the attached patch the user is taken from this extension and e.g. with userdb=ldap you can use the filter string user_filter = (&(objectClass=posixAccount)(uid=%u)) A good solution to use booth, the common name and the UniqueIdentifier is to extend settings like ssl_username_from_cert = no | yes | cn | uid where "yes" is similar to "cn".

[Dovecot] Server Timed Out: Outlook Express
by Jackie Hunt 09 Sep '07

09 Sep '07

Hi all, We just started running Dovecot this fall here on campus v 1.0. I've started getting some trouble reports from users. An Outlook Express users reported seeing the "Server has not responded in 60 seconds" messages. Waiting longer doesn't help, he has to stop/start Outlook Express to get connected again. Also have a Thunderbird user who is seeing that type of behavior first thing in the morning after being logged in all night. He has to stop/restart Thunderbird. Also, have had some reports of "disconnected" showing up on the Outlook2007 status bar. I've looked at the Dovecot log, and don't see any errors. I do see lots of "Disconnected", "Disconnected in IDLE" and "Disconnected: Logged Out". These last two seem normal, if I just see "Disconnected" is that a flag that we're losing connections abnormally? I know version 1.0.3 is out. I've looked at the changes, and the only one I can see that might be related to what we are seeing is the IDLE commmand fix. Was hoping for some advice on whether upgrading might resolve these issue. Any insight would be greatly appreciated. Jackie --- Jackie Hunt ACNS Voice: (970) 663-3789 Colorado State University FAX: (970) 491-1958 Fort Collins, CO 80523 Email: jackie.hunt(a)colostate.edu

[Dovecot] LDA bouncing mails after upgrade -- again
by Milan Holzäpfel 09 Sep '07

09 Sep '07

Hi Timo, some time ago (2007-03-24 and following) I asked whether it was intended that Dovecot deliver bounces mails (by terminating with status 89) if the deliver version is older than the rest of the dovecot installation. You replied that it was a bug, and that it had been fixed in <URL:http://dovecot.org/list/dovecot-cvs/2007-March/008346.html>. When I upgraded from Dovecot 1.0.2 to 1.0.3 a few days ago, I found out that this problem probably still exists: | Aug 28 09:38:03 host.example.org deliver(user(a)example.org): Module is for different version 1.0.3: /usr/lib/dovecot/lda/lib10_quota_plugin.so | Aug 28 09:38:03 host.example.org postfix/pipe[18356]: <ID>: to=<user(a)example.org>, relay=dovecot, delay=0.4, delays=0.13/0.09/0/0.18, dsn=5.3.0, status=bounced (Command died with status 89: "/usr/libexec/dovecot/postfix-deliver/deliver") The error message I posted in march was: | Mar 22 20:29:20 host.example.org deliver(user(a)example.org): Module is for different version 1.0.rc27: /usr/lib/dovecot/lda/lib10_quota_plugin.so | Mar 22 20:29:20 host.example.org postfix/pipe[17344]: <ID>: to=<user(a)example.org>, relay=dovecot, delay=1.9, delays=1.5/0/0/0.35, dsn=5.3.0, status=bounced (Command died with status 89: "/usr/libexec/dovecot/postfix-deliver/deliver") I suppose you still want to fix it.

[Dovecot] processing Dovecot maildirs with shell scripts
by M. Fioretti 09 Sep '07

09 Sep '07

Hello, I have a postfix server which uses procmail as its delivery agent to deliver incoming messages to several maildirs. For several reasons, not really relevant here, I need to process/refilter/sort again the content of these mailboxes before delivering the messages to the _other_ maildirs which Dovecot sees and serves to local or remote imap users. Basically, I need to write some shell scripts that, from cron jobs, regularly do this: foreach file in some_incoming_mailbox/new/ do #process the file and/or set some variable according to its content delete the file or mv it to some_other_maildir/new/ where the actual action and value of some_other_maildir is set every time by the "process the file" part of the script. The part that I still miss is guidelines to do these things safely, that is without losing or corrupting messages or doing anything else that would confuse dovecot. For example, under which conditions it is sure to move or delete (the Unix way, with mv or rm) a message from mailbox1/new/ to mailbox2/new, when the latter is served via dovecot to remote users? What is advisable and most efficient? Use locks (how?), only work on file which are at least one minute old? Should I move the messages to tmp instead of new? What else? Tips or pointers about this are very welcome. Ciao, Marco

[Dovecot] Index and Thunderbird
by Jon 09 Sep '07

Hi, Whitbox Linux 3 (RHEL) Dovecot 1.0.rc29 Using NFS From time to time does all mail get re-downloaded to Thunderbird. I would believe this has something to do with an index problem.

[Dovecot] passing quota to deliver via command line
by bill-dovecot＠carpenter.ORG 09 Sep '07

09 Sep '07

Is there any way to pass things like "quota=" for the quota plugin to the deliver LDA via the command line or as an environment variable or whatever? I've got all the info I need in my MTA to avoid a userdb lookup in the LDA, but I still have to do the userdb query to get the per-user quota number (the default quota works fine, of course). -- bill-dovecot(a)carpenter.ORG (WJCarpenter) PGP 0x91865119 38 95 1B 69 C9 C6 3D 25 73 46 32 04 69 D6 ED F3

[Dovecot] passdb/userdb args
by Daniel L. Miller 09 Sep '07

09 Sep '07

I'm a bit unclear on these - give me a moment to ramble on. I should mention I'm using version 1.0.3, my primary backend is LDAP, and I do NOT want to store user mail folders in my LDAP directory. I currently have the following: default_mail_env = maildir:/var/mail/%d/%n passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } # Instructions for deliver state a userdb is still required if using prefetch userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } userdb prefetch { } My dovecot-ldap.conf is pretty simple - the trimmed version is: hosts = localhost auth_bind = no user_attrs = %d/%n=mail user_filter = (mail=%u) pass_attrs = (&(userPassword=password)(mail=%u)) user_global_uid = 5000 user_global_gid = 8 I recognize that the pass_attrs is incorrect for a prefetch config - but I couldn't get it to work. My mail folder structure is /var/mail/domain/username. If, under 1.0.3, I can't use the %d/%n variables to build the user/home/mail parameters in the LDAP config, can I do it in the configuration stanza? Something like: passdb ldap{ args = home=%dn/%n mail=%d/%n /etc/dovecot/dovecot.conf } -- Daniel

[Dovecot] Timeout while waiting for lock for transaction log file

I have a user that gets client timeout errors when he tries to delete/clean up his massive "Spam" folder (many thousands of mail messages). He uses Thunderbird and has it configured to use "Move to Trash" when he deletes messages. I find the following in Dovecot's log file when it happens: Aug 28 10:38:22 ifm.liu.se dovecot: [ID 107833 mail.error] IMAP(bpn): Timeout while waiting for lock for transaction log file /home/bpn/Maildir/.Trash/dovecot.index.log Aug 28 10:38:24 ifm.liu.se dovecot: [ID 107833 mail.info] IMAP(bpn): Disconnected Any suggestions on what I can tuned/fix in Dovecot to solve this issue?

[Dovecot] trouble with deliver in 1.0.4
by Jack Bailey 09 Sep '07

09 Sep '07

Ok, here's one for the idiot file. I just installed dovecot-1.0.4 on my personal system for testing, a system which has to be the simplest dovecot configuration possible. deliver is barking about something with which version 1.0.3 has no problem. I looked over the wiki, googled, and see nothing wrong. The error: deliver(jjb): Sep 07 21:39:40 Fatal: Failed to create storage for 'jjb' with mail 'mbox:/HOME_DIRECTORY_USED_BUT_NOT_GIVEN_BY_USERDB/:INBOX=/var/mail/jjb' In dovecot.conf: userdb passwd { # [blocking=yes] - By default the lookups are done in the main dovecot-auth # process. This setting causes the lookups to be done in auth worker # processes. Useful with remote NSS lookups that may block. # NOTE: Be sure to use this setting with nss_ldap or users might get # logged in as each others! #args = args = blocking=yes } and mail_location = mbox:~/:INBOX=/var/mail/%u Clues generously accepted, Jack

[Dovecot] Two newbie problems
by Timothy Murphy 08 Sep '07

08 Sep '07

I've started running dovecot on my server under Fedora 7, to act as an IMAPS server for kmail. 1. I see my email fine on my laptop in an IMAPS account, but it doesn't get updated - I mean I don't get any new email - until I run kmail on my server. This isn't a great problem, as I am always logged to the server with ssh, and I just start kmail and stop it after a few minutes. Then I run kmail on my laptop, and the new mail is there. But I assume this is not the intended system? 2. I opted (probably mistakenly) to set ~/Mail/inbox/ as my base IMAPS directory on my server. I'd like to change this to ~/Maildir (I use maildir folders). Is it relatively easy to do this? I tried copying my email to ~/Maildir/ and changing the setting in /etc/dovecot.conf (and restarting dovecot), but for some reason I could not see the email on my laptop. Any advice or suggestions gratefully received.

[Dovecot] o/s tuning for imap

I'm switching from a pop3 only dovecot install to a pop3/imap install and I'm wondering how many connections every 100 'normal' imap users might have/keep open? I'm wondering if I need to tweak any o/s related things, like time_wait, etc. Any pointers would be greatly appreciated. Thanks, Ken A.

Also taken from WIKI http://wiki.dovecot.org/VirtualUsers You can create for example one vmail user which owns all the mails, or you can assign a separate UID for each user. See UserIds#mailusers for more information about different ways to allocate UIDs for users. All I want is to be able to access the mail, with the same my "virtual_uid_maps = static:501"(set in my postfix main.cf) All of these say it can be done, but how do I do it? Please could someone assist me :( Thanks. Neil -- This email and all contents are subject to the following disclaimer: http://www.dcdata.co.za/emaildisclaimer.html

[Dovecot] Quota bug in deliver?
by FORMER 03 | Baltasar Cevc 06 Sep '07

06 Sep '07

Hi, I may be wrong, but I suspect a bug in dovecot deliver when using quotas. I've put some mails into a mailbox and then reduced the quota, to have the mailbox be over quota - here's the quota informaiton: [...] 2 getquotaroot INBOX * QUOTAROOT "INBOX" "" * QUOTA "" (STORAGE 880 5) 2 OK Getquotaroot completed. [...] When I have a setup with quotas only in the database, everything works as expected and deliver denies the message: Sep 5 21:50:14 ms4 deliver(postfach(a)email5.former03.local): msgid=<20070905195014.9D874239C007(a)ms4.srv.hoster03.de>: save failed to INBOX: Quota exceed ed Sep 5 21:50:14 ms4 deliver(postfach(a)email5.former03.local): msgid=<20070905195014.9D874239C007(a)ms4.srv.hoster03.de>: Rejected: Quota exceeded When I put a standard quota into the config as follows, the delivery succeeds (apparently deliver checks the standard quota, while IMAP correctly checks the quota from the database if it is returned. Sep 5 21:46:11 ms4 deliver(postfach(a)email5.former03.local): msgid=<20070905194611.9FE49239C007(a)ms4.srv.hoster03.de>: saved mail to INBOX The mailbox is still over quota here, but deliver does not seem to notice. == standard quota in the config plugin { quota = maildir:storage=102400:messages=1000 [...] } In case I've overlooked something, please let me know.

[Dovecot] securing dovecot proxy connections
by bill-dovecot＠carpenter.ORG 06 Sep '07

06 Sep '07

The wiki <http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy> page says this: "The connections created to the destination server can't be TLS/SSL encrypted.". Hrmm. Right now, with perdition, I'm forcing the use of STARTTLS on the internal connections. I'd just as soon get rid of perdition (to have one less moving part in my architecture), but I need the secure connections. Is there a way to configure dovecot's internal proxy connections to use STARTTLS or some other SSL/TLS level of security? (Without a bunch more research, I don't know what the interaction is between the real client, the dovecot proxy, and the destination server.) -- bill-dovecot(a)carpenter.ORG (WJCarpenter) PGP 0x91865119 38 95 1B 69 C9 C6 3D 25 73 46 32 04 69 D6 ED F3

[Dovecot] How do I use sieve to move bounces?
by Jef Driesen 06 Sep '07

06 Sep '07

How can I use sieve to move bounces and non delivery reports (i.e. anything with an empty envelope from) to a special mailbox? I placed this snippet at the start of my sieve script require ["envelope", "fileinto"]; if envelope :is "from" "" { fileinto "INBOX.Reports"; stop; } But mails are not moved to the reports mailbox, and they are still processed by the rest of the script.

[Dovecot] OT Project idea: IMAP plugin for Google Desktop
by Kenneth Porter 06 Sep '07

06 Sep '07

Posting here, as Dovecot seems to be the premier IMAP server available. In case anyone is looking for something to work on, I found today that Google Desktop only understands email clients that keep mail on the client, and it would be nice if there was a plugin that understood IMAP. Here's a site that seems to explain how to write such plugins: <http://www.plugindevelopment.com/>

[Dovecot] alert function (possible WIBNI)
by Stewart Dean 05 Sep '07

05 Sep '07

The imapd spec has a provision for an alert pop-up of any ASCII text message contained in /etc/imapd.alert on the IMAP server. Can I assume this is implemented on DC? It'd be real nice if in addition to the current all-users message, it was possible to do a per-user alert...but I guess that would be something for IMAP standards....... -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Dovecot + Sieve
by Marcin M. Jessa 04 Sep '07

04 Sep '07

Hi guys. I installed dovecot 1.0.3 with sieve plugin. It looks like sieve is loaded fine by dovecot [1]. I set up dovecot to use sieve globally: protocol lda { mail_plugins = cmusieve quota sieve_global_dir = /usr/local/etc/sieve/Junk ..... } And created a sieve file which is supposed to move all the Spam marked by dspam to users's Junk folder (listed as Junk in the subscriptions file) : require ["fileinto"]; # Move spam to Junk folder if header :contains ["X-DSPAM-Result:"] "Spam" { fileinto "Junk"; # Stop here so that we do not reply on spams stop; } I also set up postfix to use pipe mail through dovecot: mailbox_command = /usr/local/libexec/dovecot/deliver The problem is dovecot seems to be ignoring my sieve rule and delivers emails directly to INBOX. Any idea how to fix that?

[Dovecot] rule of thumb for indexing overhead
by bill-dovecot＠carpenter.ORG 30 Aug '07

30 Aug '07

I realize it's hard to be precise about this, but does anyone have a feel or rule of thumb for a couple of aspects of indexing overhead? 1. Proportionally, how much space does it take for all 4 files? If I want to give my users a quota of 100 MB for messages, how much real space should I plan for so that I won't run out of space for indexing? 2. What's the overhead in rebuilding index files? Suppose I use an LDA other than dovecot, so at least the INBOX index is frequently getting out of date. Does it cost much (in CPU, memory, and disk IO) to rebuild the index files? (I'm using maildir.)

[Dovecot] (slightly OT) syncing / migrating IMAP mailboxes
by Gunter Ohrner 28 Aug '07

28 Aug '07

Hi! I fear this may be slightly off-topic but it's both related to IMAP and to dovecot: Is there any good and in paticular realiable program for synching / migrating one IMAP mailbox to another? The most important features for me is that a) no mails are lost / left out silently and b) the porgram is able to sync the complete mailbox including all folders without just giving up in the middle of the transfer. If it's somehow possible, I'd like to migrate directly from one IMAP account to the other, without running the synchronizer on one of the servers and without accessing one of the Maildirs directly. I simply want to migrate my existing IMAP account from one Dovecot server (running 1.0beta5) to a new one (running 1.0rc15, as that's the version in Debian stable). Actually, a large part of the mailbox including most / all folders is already present on both servers, but I recently noticed that a few thousand mails are still missing. The current mailbox state is the result of two earlier (obviously incomplete :-( ) migrations a few months ago, from the original Dovecot 1.0beta5 server to a Cyrus server, and - shortly thereafter - from there on to the currently used Dovecot 1.0rc15. So far I've tried offlineimap, imapsync and mailsync, none of which seems to be really usuable. :-( The current state with the incomplete mailbox was caused by mailsync. When I did the first two migrations, mailsync looked like the only program which worked, but seems to have "forgotten" the missing messages. Another extremely suspicious thing is that mailsync reports "phantom changes" if run again immediately after synching a folder and will start to delete and copy / "sync" dozends of messages even if none of the folders actually changed after synching. I've read the name "imapsync" on this list several times, but I just tried it and just tried version 1.219. It happily starts synching the mailboxes and copying messages, but stops after partially synching the first folder - it simply exists, leaving no informational or error message whatsoever... Restarting imapsync will not help, it will appear to start synching the first folder again, but silently exit without doing anything. Some of you seem to use imapsync as a migration tool for production systems, how do you cope with these situations and how do you ensure a mailboxs' migration actually completed successfully? As you're probably not playing Roulette with your customers' or companie's eMails, I'm interested in your receipts to successfully use imapsync myself. As the third application I tried offlineimap (4.0.x-branch). During the migration a few months ago offlineimap (4.0.16 IIRC, synching from a Maildir to a remote IMAP account) was unusuable as it continuously and reproducibly threw exceptions at me during syncing obviously caused by specific messages in the accounts. Unfortunately, I wasn't able ti get any successful help on the offlineimap mailing list this time. :-( Now, synching from one IMAP account to another, specifiying the new server as the "local" account, offlineimap did not throw exceptions caused by mail messages so far, but it's performance is unusuable. It seems to use the "local" IMAP account on my target sevrer in a way which causes Dovecot to utilize all CPU power, copying one message every 10 to 20 seconds - this way, a sync would take ages and frequently aborts because of connection problems. The target server is an Athlon64 3700+ machine... So, does anyone have any pratical solution on how to migrate one IMAP mailbox to another? For various reasons I'd really prefer to go with a tested and working, reliable solution instead of starting to debug complex non-working programs I do not halfway understand and for which I cannot seem to get reliably support from its authors and/or its user community... :-/ Thanks a lot in advance for any pointers to a solution, Gunter -- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ "The obvious mathematical breakthrough would be development of an easy way to factor large prime numbers." -- Bill Gates from The Road Ahead, p265 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ + PGP-verschlüsselte Mails bevorzugt! + +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

[Dovecot] Some customers receiving duplicate e-mails
by Patrick - South Valley Internet 28 Aug '07

28 Aug '07

Hi all, I posted this question in the Postfix users mailing list as well - I'm not sure if this is Dovecot or Postfix related. Our old system which we migrated off of was an AIX 5.2 machine running most recent Postfix and mbox format with UW-IMAP. We've migrated to most recent Postfix, using Maildir and Dovecot v1. After we used mb2md to migrate over all our customers, some of our customers have called in to let us know they are receiving duplicate e-mails. It's not happening to everyone, it's random (well, I'm sure it's not really random, I haven't found the issue yet). I don't even know where to start. I looked at the logs, but everything looks fine. How can I troubleshoot something like this? Have any of you experienced the same issue? Thanks in advance.

[Dovecot] MANAGESIEVE patch v7 for dovecot 1.0.3
by Stephan Bosch 27 Aug '07

27 Aug '07

Hello dovecot users, I have updated the MANAGESIEVE patch to fix a recently reported problem. This is a patch against the latest stable release 1.0.3. It currently won't compile with 1.1 due to significant changes in the master code. Change Log V7 ------------- - Robin Breathe indicated that the regex capability was missing in the server's SIEVE listing. It turns out I forgot to make arrangements for setting ENABLE_REGEX in the cmu libsieve sources, so the regex extension was not compiled in. I copied the configure.in section regarding ENABLE_REGEX from dovecot-sieve-1.0.2 and that fixed the problem. This patch still includes (yet another) instance of the CMU Sieve source, as explained in one of my previous e-mails (http://dovecot.org/list/dovecot/2006-July/015016.html) The patch can be downloaded at: http://sinas.rename-it.nl/~sirius/dovecot-1.0.3-MANAGESIEVE-v7.diff.gz The README.managesieve is located in the root of the dovecot source tree after applying the patch. Have fun testing the patch. Don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

[Dovecot] Restoring a deleted/moved imap folder
by Oliver Schulze L. 27 Aug '07

27 Aug '07

Hi, one user of my imap server just deleted a whole folder, blame thunderbird I have the server disk and running Stellar Info for deleted files recovery. My cuestion is about how dovecot deleted an imap Maildir folder? The imap client is configured to move the deleted mails to the Trash folder, so I think dovecot would delete every Maildir email after successfully moved it. In the case a folder is deleted, is something special dovecot does to the email? Or it just run the unlink() function? In the case of compacting a folder, I think thats just a client side action. Many thanks Oliver -- Oliver Schulze L. | http://tinymailto.com/oliver Asuncion - Paraguay | http://www.solojuegos.mobi

[Dovecot] Dovecot should raise the limit of file descriptors at startup...
by Peter Eriksson 27 Aug '07

We've run into a situation where the Dovecot master process "dovecot" runs out of file descriptors on Solaris 10 since the default is only 256: # plimit 1 1: /sbin/init resource current maximum time(seconds) unlimited unlimited file(blocks) unlimited unlimited data(kbytes) unlimited unlimited stack(kbytes) 8192 unlimited coredump(blocks) unlimited unlimited nofiles(descriptors) 256 65536 vmemory(kbytes) unlimited unlimited Output from "pfiles" after we raised the limit manually: # pfiles 26378 | head -10 26378: /ifm/sbin/dovecot -c /etc/dovecot.conf Current rlimit: 16384 file descriptors 0: S_IFCHR mode:0666 dev:327,15 ino:18128 uid:0 gid:3 rdev:13,2 O_RDONLY|O_LARGEFILE /export/zones/dovecot/root/dev/null 1: S_IFCHR mode:0666 dev:327,15 ino:18128 uid:0 gid:3 rdev:13,2 O_RDONLY|O_LARGEFILE /export/zones/dovecot/root/dev/null 2: S_IFCHR mode:0666 dev:327,15 ino:18128 uid:0 gid:3 rdev:13,2 O_RDONLY|O_LARGEFILE # pfiles 26378 | tail -10 243: S_IFIFO mode:0000 dev:324,0 ino:2038192 uid:0 gid:0 size:0 O_RDWR|O_NONBLOCK FD_CLOEXEC 246: S_IFIFO mode:0000 dev:324,0 ino:2048002 uid:0 gid:0 size:0 O_RDWR|O_NONBLOCK FD_CLOEXEC 247: S_IFIFO mode:0000 dev:324,0 ino:2048441 uid:0 gid:0 size:0 O_RDWR|O_NONBLOCK FD_CLOEXEC 258: S_IFIFO mode:0000 dev:324,0 ino:2042076 uid:0 gid:0 size:0 O_RDWR|O_NONBLOCK FD_CLOEXEC 459: S_IFIFO mode:0000 dev:324,0 ino:1311426 uid:0 gid:0 size:0 O_RDWR|O_NONBLOCK FD_CLOEXEC Perhaps the Dovecot master process should raise it's own limit to the allowed maximum when it starts? (getrlimit()+setrlimit()), or be user configurable? Has this been discussed somewhere before? - Peter

It gets confusing if %n and %d sometimes change, but > sometimes don't. True, I hadn't thought about that. I'm not much of a C programmer especially in the scheme of something as complex as Dovecot... but if you could be so kind as to point me within a couple of metres of the location in the code where the changes to %n and %d get made by auth_username_format, I'll try to patch something myself locally on my servers to get the result I need for now and leave it up to you to decide if it's worthwhile adding additional variables at some point down the road to expose the original values.

[Dovecot] authentication with mysql - problem with table name escaping
by XhE 26 Aug '07

26 Aug '07

Found a problem with dovecot 1.0.3 and mysql authentication I got a problem with escaping of mysql table names. Usually, when a mysql table name has some special character (in my case there is a table beginning with the # character) one has to put into these special quotes --- ` ---; others like ' oder " are not recognized. But dovecot somehow doesn't allow me to do that. After switchting auth_verbose to true I get entries in /var/log/messages stating: Password query failed: Incorrect table name ' ' Regards, XhE

[Dovecot] Authentication using only TLS client certificates
by Martin Lambers 26 Aug '07

26 Aug '07

Hi! I'd like to configure dovecot to use only TLS client certificates for authentication. After the user presented a client certificate and that certificate was verified, no password-based authentication should be necessary anymore. Is this currently possible? Or would this require support for the SASL EXTERNAL mechanism? Regards, Martin

[Dovecot] Log format question...
by Mike Cisar 26 Aug '07

26 Aug '07

Trying to do a little (cosmetic) tweak to my configuration and just don't seem to be able to come up with a set of options that works. My POP/IMAP configuration is working just fine in terms of mail retrieval, etc. What I'm seeing in the logs now is... Aug 13 18:15:17 test2 dovecot: pop3-login: Login: user=<support>, method=PLAIN, rip=10.11.12.12, lip=10.11.12.13 I would prefer (for ease of troubleshooting) to have "user=<support(a)realm.com>" appear in the logs instead, to save having to figure the realm from the IP value. Have played around with various combinations of %u, %n and %d and all I seem to be able to accomplish is break the working part of the config. I'm sure the answer is probably something simple, or some combination I haven't tried... but it's certainly escaping me at the moment. The relevant (I think) part of my config follows. The usernames in the mentioned passwd and shadow files are in the 'user' format (ie. not 'user@realm'). --snip-- mail_location = mbox:/vhome/%l/home/%n/mail:INBOX=/var/spool/vmail/%l/%n auth_username_format = %n passdb passwd-file { args = /etc/vmail/shadow.%l } userdb passwd-file { args = /etc/vmail/passwd.%l } login_log_format_elements = user=<%u> method=%m rip=%r lip=%l %c --snip-- Hints and suggestions appreciated!

[Dovecot] removing IMAP keywords?
by martin f krafft 25 Aug '07

25 Aug '07

Hi there, I found that with an IMAP command like <unique-leader> STORE 1 +FLAGS (testflag) I can set arbitrary flags on mails through the dovecot IMAP daemon. This rules. Now I wonder, however, how I can remove those flags, which become properties of the folder, really. For instance, after the above, SELECT on the containing folder gives: * FLAGS (\Answered \Flagged \Deleted \Seen \Draft testflag) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft testflag \*)] Flags permitted. Even if I remove the flag from all messages or even delete all messages in the folder, the flag stays on the folder. Is there an IMAP way of removing flags from a folder? Also, does someone know where I can find specification on what characters are allowed for keywords? RFC 3501 is strangely quiet on this, or I am blind.
