[Dovecot] Delivered-To header without +extension ?
by Per Jessen 21 Jan '11

21 Jan '11

I'm running postfix 2.6.2 and dovecot 2.0.9, and I've just switched to delivering mails to dovecot via lmtp. It looks like the Delivered-To: header is slightly different - it doesn't seem to include the +extension? Is this intentional or does the +extension somehow get in the way? /Per Jessen, Zürich

[Dovecot] Fwd: Re: Dotlock dovecot-uidlist errors / NFS / High Load
by list＠airstreamcomm.net 21 Jan '11

21 Jan '11

Stan, Thanks for the reply. In our case we have actually already done most of the work you suggested to no avail. We had rebuilt two new ntp servers that sync against two stratum 1 sources, and all our nfs clients, regardless of using dovecot, sync to those two machines. You bring up the difference between bare metal and hypervisor, and we are running these machines on vmware 4.0. All the vmware knowledge base articles tend to push us towards ntp, and since we are using centos 5.5 there are no kernel modifications that need to be made regarding timing from what we can find. I will give the ntpdate option a try and see what happens. I was also hoping to understand why the uidlist file is the only file that uses dotlock, or if there was plans to give it the option to use other locking mechanisms in the future. Thanks again!

In a clustered server environment, _always_ run a local physical box/router ntpd server (preferably two) that queries a set of external sources, and services your internal machine queries. With RTTs all on your LAN, and using the same internal time sources for every query, this clock drift issue should be eliminated. Obviously, when you first set this up, stop ntpd and run ntpdate to get an initial time sync for each cluster host. If after setting this up, and we're dealing with bare metal cluster member servers, then I'd guess you've got a failed/defective clock chip on one host. If this is Linux, you can work around that by changing the local time source. There are something like 5 options. Google for "Linux time" or similar. Or, simply replace the hardware--RTC chip, mobo, etc. If any of these cluster members are virtual machines, regardless of hypervisor, I'd recommend disabling using ntpd, and cron'ing ntpdate to run once every 5 minutes, or once a a minute, whatever it takes to get the times to remain synced, against your local ntpd server mentioned above. I got to the point with VMWare ESX that I could make any Linux distro VM of 2.4 or 2.6 stay within one minute a month before needing a manual ntdate against our local time source. The time required to get to that point is a total waste. Cron'ing ntpdate as I mentioned is the quick, reliable way to solve this issue, if you're using VMs. -- Stan

[Dovecot] Populating mailbox dir
by Mauricio Tavares 20 Jan '11

20 Jan '11

Let's say you created a (virtual) mail user but have not created the user mail directory. When you first try to access it, the mail directory is created and populated: ls -a /var/spool/vmail/domain.com/raub/ . dovecot.index.log dovecot-uidvalidity.4d375a39 tmp .. dovecot-uidlist new .Trash cur dovecot-uidvalidity subscriptions Who populates/creates the initial files and folders in the user mailbox? Dovecot? The mail client accessing it through imap? Elvis? If dovecot, is there a way to customize it a bit, so a few extra folders will also be thrown there?

[Dovecot] domain stripping
by PA 20 Jan '11

20 Jan '11

Hi, using dovecot 2.0 and I'm using a couple of user DBs, sql/prefetch and pam. Currently if the user logins with username@domain it authenticates off the sql DB and works fine. If the user logins with username with no @domain it fails on the sql lookup and succeeds on the pam user DB. However I was wondering if I can have another sql DB lookup that says when the user logins and fails against the first two user DBs, sql/pam db, to try this last sql user DB and appends a default domain to it, because the sql DB lists username with the domain. Currently I have all users login in with no realm on the older mail server and I wanted to migrate these users to dovecot 2.x with minimal impact and wanted to have the ability for these virtual users to login with and without a realm. Thanks paul.

[Dovecot] Bug found, assertion failed
by Tobias Daucher 20 Jan '11

20 Jan '11

Hi there, We're running dovecot 2.06, with mdbox. Following message was in our syslog: Jan 20 09:26:48 servername dovecot: [ID 583609 mail.crit] imap(user): Panic: file istream-limit.c: line 79: assertion failed: (v_offset <= lstream->v_size) The problem could be solved on client side, by just deleting the ImapMail-Folder in Thunderbird. Why? Thunderbird tried to move a message, that obviously wasn't there. Dovecot got killed and the message above was in the syslog. Connection was closed and Thunderbird told me the server is dead. Thunderbird tried this every few seconds, and there was no way to say thunderbird "stop try moving". So the only way was to delete thunderbirds mail cache. I think it would be very nice, if dovecot doesn't die, just because the client tries to move a message, which isn't there.

Its locking model is incredibly slow (500 locks/second on a filesystem mounted with quotas enabled and noatime) and results in dire performance - plus there's a known crash vulnerability if files are repeatedly renamed in large directories (this bites us regularly...) GFS2 isn't an "enterprise" filesystem by any stretch of the imagination, despite what a number of enthusiastic salespeople might try to convince you of. We're lucky to keep the GFS servers up for more than a week at a time.

[Dovecot] Upgrading from 1.2 to 2.0
by list＠airstreamcomm.net 20 Jan '11

20 Jan '11

Greetings Dovecot mailing list! We are an ISP that recently migrated from Courier to Dovecot, and are looking at the next round of upgrades. Hoping that we could get pointed to some documentation or get a general list of best practices for an upgrade from 1.2.13 to 2.0.9. Our current environment consists of four Dovecot machines that share an NFS backend hosting POP and IMAP. Our biggest question is whether we can support a rolling upgrade from 1.2.13 to 2.0.9, or if it would need to be an all for one cut. Thanks in advance.

[Dovecot] Problem with seeing mail after Upgrade from Courier
by apettitt 19 Jan '11

19 Jan '11

I created a new server for a webmail system because the old server crashed. When I created the server, I installed Dovecot and the old server had Courier. On the new server, I'm doing virtual users where the old one created system users. I moved all the folders over for all the users on to the new server and ran the Courier-Dovecot migration script. The files were created successfully with no issues. The issue I'm having now is that Dovecot is not seeing any mail in the user's directory. If I create a new user, it can send and receive mail with no problems. If I send an email to an existing user, it gets delivered to the new folder but dovecot does not see anything in the new folder. There is also mail in the curr folder that dovecot does not see. I'm using Roundcube as a webmail client but I've also tried using Telnet with the same results. Any ideas? -- View this message in context: http://old.nabble.com/Problem-with-seeing-mail-after-Upgrade-from-Courier-t… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Strange issue in NFS

Hi Timo... It's happens some strange issue with my maildir using NFS. If i use a Local Hard disk, i don't get any of this messages about memory error. Jan 12 10:57:50 brc dovecot: imap(alex(a)exemplo.com.br): Error: opendir(/storage/nfs/3/emexis/messages/ exemplo.com.br/alex/Maildir/.Drafts/new) failed: Cannot allocate memory Jan 12 10:57:51 brc last message repeated 4 times Jan 12 10:57:59 brc dovecot: imap(alex(a)exemplo.com.br): Fatal: block_alloc(262144): Out of memory Jan 12 10:57:59 brc dovecot: imap(alex(a)exemplo.com.br): Error: Raw backtrace: /opt/addons/lib/dovecot/libdovecot.so.0 [0xb768fcbe] -> /opt/addons/lib/dovecot/libdovecot.so.0 [0xb768fd1d] -> /opt/addons/lib/dovecot/libdovecot.so.0 [0xb768f273] -> /opt/addons/lib/dovecot/libdovecot.so.0 [0xb76a0183] -> /opt/addons/lib/dovecot/libdovecot.so.0 [0xb76a01cc] -> /opt/addons/lib/dovecot/libdovecot.so.0(p_strdup+0x40) [0xb76ad980] -> /opt/addons/lib/dovecot/libdovecot-storage.so.0(maildir_save_add+0x7c) [0xb7717f0c] -> /opt/addons/lib/dovecot/libdovecot-storage.so.0(maildir_copy+0x18d) [0xb7719bbd] -> /opt/addons/lib/dovecot/lib20_emexis_uis_plugin.so [0xb74fda6a] -> /opt/addons/lib/dovecot/libdovecot-storage.so.0(mailbox_copy+0x58) [0xb76ea258] -> dovecot/imap(cmd_copy+0x1cf) [0x804f87f] -> dovecot/imap(cmd_uid+0x7f) [0x80551bf] -> dovecot/imap [0x8055f0c] -> dovecot/imap [0x8055fbb] -> dovecot/imap(client_handle_input+0x3f) [0x805610f] -> dovecot/imap(client_input+0x5f) [0x8056acf] -> /opt/addons/lib/dovecot/libdo Jan 12 10:57:59 brc dovecot: master: Error: service(imap): child 28315 returned error 83 (Out of memory (vsz_limit=256 MB, you may need to increase it)) I Try to increase the vsz_limit in imap to 2048 MB, and i try too , put 0 MB (like no limit) and i still get this same error (only change the vsz_limit to my write limit).

[Dovecot] Duplicate mail for forwards (dovecot+postfix+postfixadmin)
by Darek M 19 Jan '11

19 Jan '11

Dovecot 1.2.11, using postfixAdmin 2.3 to manage, basically using the postfixadmin schema and sql queries during install. - If I set a forward for an account to go to a remote email address, no dupes. - If I set a forward for an account to go to an email address on the same system, I get a dupe in the inbox of the second address. So if account1(a)domain.com has account2(a)domain.com as a forward, account2@ receives two copies of the same message, completely identical, same message IDs, same md5 sum. If I add account3@ into the mix, account3@ will also receive two copies of each message. I will also get a duplicate if I forward mail to account(a)anotherdomain.com, where anotherdomain.com is also hosted on the same system. account1(a)domain.com receives one copy. Here is the Dovecot log: Jan 18 17:24:40 deliver(account2(a)domain.com): Info: msgid=<4D361323.3040000(a)srvr.net>: saved mail to INBOX Jan 18 17:24:40 deliver(account1(a)domain.com): Info: msgid=<4D361323.3040000(a)srvr.net>: saved mail to INBOX Jan 18 17:24:40 deliver(account2(a)domain.com): Info: msgid=<4D361323.3040000(a)srvr.net>: saved mail to INBOX Postfix logs only show one delivery for each message, and since the headers aren't changed at all, I think the lda is at fault here. This is the entry for the account in the 'alias' table ======================== mysql> select * from alias where address='account1(a)domain.com'; +-----------------------+----------------------------------------+------------+---------------------+---------------------+--------+ | address | goto | domain | created | modified | active | +-----------------------+----------------------------------------+------------+---------------------+---------------------+--------+ | account1(a)domain.com | account1@domain.com,account2@domain.com | nyinet.com | 2010-11-28 18:07:40 | 2011-01-18 17:04:03 | 1 | Anyone have an idea of what I should be looking at in a situation like this? Does the 'goto' field look fine? -- Darek

Hi there, I changed postfix to pass email to spamassassin, and then deliver to dovecot LDA. It fails to deliver. The current entry in master.cf now reads: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -d ${recipient} smtp inet n - - - - smtpd -o content_filter=spamassassin spamassassin unix - n n - - pipe user=nobody argv=/usr/bin/spamc -f -e /usr/sbin/sendmail -oi -f ${sender} ${recipient} This is the same as I had to afore I factored in spamassassin. The error message is this:- Jan 18 16:30:44 logout postfix/pipe[28952]: 56AE58230A: to=<test(a)test.info>, relay=dovecot, delay=0.01, delays=0/0/0/0.01, dsn=5.3.0, status=bounced (command line usage error. Command output: Fatal: Unknown argument: flags=DRhu Usage: deliver [-c <config file>] [-a <address>] [-d <username>] [-p <path>] [-f <envelope sender>] [-m <mailbox>] [-n] [-s] [-e] [-k] ) Does anyone know which options I should have added to dovecot deliver?

[Dovecot] v2.0.9 released
by Timo Sirainen 18 Jan '11

18 Jan '11

http://dovecot.org/releases/2.0/dovecot-2.0.9.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.9.tar.gz.sig I'm still lagging behind in my email, but I guess it's time to release v2.0.9 anyway. - Linux: Fixed a high system CPU usage / high context switch count performance problem - Maildir: Avoid unnecessarily reading dovecot-uidlist while opening mailbox. - Maildir: Fixed renaming child mailboxes when namespace had a prefix. - mdbox: Don't leave partially written messages to mdbox files when aborting saving. - Fixed master user logins when using userdb prefetch - lda: Fixed a crash when trying to send "out of quota" reply - lmtp: If delivering duplicate messages to same user's INBOX, create different GUIDs for them. This helps to avoid duplicate POP3 UIDLs when pop3_uidl_format=%g. - virtual storage: Fixed saving multiple mails in a transaction (e.g. copy multiple messages). - dsync: Saved messages' save-date was set to 1970-01-01.

[Dovecot] Question about indexes and maildir/sdbox/mdbox
by Javier de Miguel Rodríguez 18 Jan '11

18 Jan '11

Hello We are now running dovecot 2.0.9 with indexes in a ram disk and maildir storage in a test system. We have the following questions: - If there is a power outage / kernel crash, we will lose the content of ramdisk. We have tested that indexes are regenerated when a user logs in via imap, so e-mail access will be "slower" after a power outage / kernel crash, but everything should work as expected (TM). Are we missing something? - We are evaluating migrating from maildir to dbox. There are two alternatives: sdbox and mdbox. Reading about dbox in the wiki (http://wiki2.dovecot.org/MailboxFormat/dbox) we see that using a ram disk for indexes for mdbox is a really bad idea: /"Note that with dbox the Index files actually contain significant data which is held nowhere else. Index files for both *single-dbox* and *multi-dbox* contain message flags and keywords. For *multi-dbox*, the index file also contains the map_uids which link (via the "map index") to the actual message data. This data cannot be automatically recreated, so it is important that Index files are treated with the same care as message data files."/ So in mdbox we should not use a ramdisk for indexes. But what about sdbox? sdbox indexes work as maildir indexes? Are sdbox indexes bigger than maildir indexes? Thank you very much for your support Regards Javier

[Dovecot] Running two different versions of Dovecot (was: making folders unmovable)
by Dave 17 Jan '11

17 Jan '11

OK, so I decided to go ahead and just upgrade to the latest 1 series Dovecot and see if that solves my ACL/config issues I've been having. (I tried compiling 2.0.9, but it errored out and I assume that's because it's a pretty old machine/compiler.) Anyway, 1.2.16 compiled fine, and I installed it in another location from the currently running 1.1 series install. I have this new install running (IMAP) on a non-standard port while I test it out, and it starts fine and all seems well. However, I'm wondering, is it OK to run it and have it look at the same Maildir mailboxes as the currently running 1.1 series install? Does that have the potential to mess with indexes or change anything in a bad way? (FWIW, I tried it briefly, and after changing the port number in and restarting my mail client [Thunderbird], it had trouble pulling up the mailbox I was trying to access.) David

This is pretty much what I do with the mail domain I administer. I've set the INBOX with a modest quota, and a personal mail folder with a generous quota. I encourage users to keep their INBOX as a "working set", and archive the rest using any method they prefer. It forces users to process their Email (or at least their INBOX). and keeps packratting in check. Super-big INBOX quotas seem to encourage wasteful habits. I've helped some users clean out their mailboxes and was surpised at the amount of junk being kept for years and years. Apart from a few users moaning about their meager INBOX, this policy works out fairly well. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Virtual mailboxes do not look into subfolders
by Paul Provost 17 Jan '11

17 Jan '11

Hi all, I have virtual mailboxes set up as "Smart Folders" to show me messages tagged with certain keywords. For example: # ~/Maildir-virtual/fwp/dovecot-virtual File MailingLists/* KEYWORD @fwp Messages get picked up from the File mailbox, but not for the sub-mailboxes inside the MailingLists mailbox. What am I doing wrong? Wrong separator? And how can I debug this? Everything else is working fine. Thanks a lot! Paul

I think dovecot simply ignored this. I wonder if the alias quota_rule makes any sence to Dovecot as I only see : quota = dict:user::proxy::quotadict defined in the dovecot.conf and not quota_rule. # cat /etc/dovecot/dovecot-sql.conf password_query = SELECT username as user, password FROM mailbox WHERE email='%u'; user_query = SELECT 5000 AS uid, 5000 AS gid,'/home/vmail/%d/%n' as home, concat('*:storage= ', quota) AS quota_rule FROM mailbox WHERE user = '%n';

Hello list, New version of dovecot segfaulting with expire plugin(sqlite db). Steps to reproduce: 1)DB file has permitions: -rw-r--r-- 1 mail mail 87040 Янв 17 10:04 /var/mail/expire.db 2)Dict dovecot config section: service dict { # If dict proxy is used, mail processes should have access to its socket. # For example: mode=0660, group=vmail and global mail_access_groups=vmail unix_listener dict { mode = 0600 user = mail } #user = mail } 3)Trying to add new record to database I get: Jan 17 10:03:12 dict: Error: sqlite: exec(INSERT INTO expires (expire_stamp,username,mailbox) VALUES ('1294852805','user(a)domain.com','Trash')) fail ed: attempt to write a readonly database (8) Jan 17 10:03:12 IMAP(user(a)domain.com 192.168.2.252): Error: read(/var/run/dovecot/dict) failed: Remote disconnected Jan 17 10:03:12 master: Error: service(dict): child 13957 killed with signal 11 (core not dumped) This crash has gone after service dict got enough permission to access db file(user mail in my case).

[Dovecot] vpopmail disabled services fix
by Calvin 17 Jan '11

17 Jan '11

I noticed that disabling services using vpopmail was not being recognized by dovecot. Using "vmoduser -swip user(a)domain.com" should disable all services, but both pop and imap logins were still allowed. After a bit of digging in the code and confirming with a few debug lines, it appears that lines 38 and 52 of src/auth/passdb-vpopmail.c are the issue (dovecot 2.0.8). These two lines do a strcmp on request->service. It appears that request->service is in lower case, but the comparison values are in upper case. Either updating the values to lowercase or using strcasecmp should fix the issue.

[Dovecot] mail to admin when quota exceeded
by Karolis Žvaigždinas 16 Jan '11

16 Jan '11

We're using Dovecot v1.2.15 LDA/IMAP/POP3+MySQL with quota plugin, quota_rule per-user size, quota_exceed_message and quota_warning on storage=90%%.with script. Everything is working as expected. But I've been asked to configure it the way, that when a user gets message, which would make his maildir over quota limit, notification go not only to sender, but also to postmaster(a)domain.com. Browsed wiki, mailinglist archive - couldn't find anything on that. Is there a way to implement such feature? And what about possibility to send a message to user, notifying him about rejected email "from: xxx(a)yyy.com" with "subj: blah blah" due to full mailbox? Such messages are small and would not take too much space. Thus the user would know what he misses, urging him to clean his mailbox. Thank you in advance. -- Karolis

[Dovecot] [PATCH] auth: Fixed mech_winbind_ntlm by using mech_winbind_auth_initial()
by Christian Wiese 16 Jan '11

16 Jan '11

Hi folks, attached is a trivial patch which is fixing Winbind/NTLM authentication in dovecot 2.0 series. The patch was made against 2.0.8 sources, but there should be no problem applying it onto HEAD, because 'src/auth/mech-winbind.c' wasn't touched for quite some time now ;) I tested the patch with a dovecot 2.0.8 running on linux, authenticating against a WindowsServer 2008R2 Enterprise using ntlm_auth/winbind (from current stable samba 3.5.6). I successfully tested NTLM authentication for IMAP and POP3 (with and without STARTTLS) using following MUAs for the test: - Thunderbird 3.1.7 (Linux X86-64) - Outlook Express 6.00 (Windows XP Pro Qemu-KVM) Cheers, Chris Patch Description: In changeset 9002 a new function named mech_winbind_auth_initial() was introduced, but only the mech_winbind_spnego module part was changed to finally use this function. The mech_winbind_ntlm module part was not properly adapted which leads to a non functioning NTLM authentication mechanism while using winbind, because it will never call the `ntlm_auth` helper. The simple fix is to replace mech_generic_auth_initial() with mech_winbind_auth_initial() as auth_initial "hook" when setting up the mech_winbind_ntlm module, like it is done in the mech_winbind_spnego module. References: - Changeset 9002: http://hg.dovecot.org/dovecot-2.0/diff/9d0037a997f4/src/auth/mech-winbind.c

[Dovecot] Seeing other people subscribed non-shared mailboxes
by Thomas Hummel 16 Jan '11

16 Jan '11

Hello Timo, With dovecot-2.0.8/Maildir, in a simple shared mailboxes setting I noticed the following : - user "doveimap" has 2 mailboxes : "Common" and "Private" - he shares only the "Common" mailbox to user "dovepop" doing : x setacl "Common" dovepop lrwstipekxacd x OK Setacl complete. - he subscribed to both x lsub "" * * LSUB () "." "Trash" * LSUB () "." "Common" * LSUB () "." "Private" x OK Lsub completed. I'm not realy sure if the fact that "dovepop" can see doveimap's subscribed "Private" mailbox in the "#Shared" namespace is legitimate or not : x login dovepop xxxxx x OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS ACL RIGHTS=texk] Logged in x list "" * * LIST (\HasNoChildren) "." "Trash" * LIST (\HasNoChildren) "." "INBOX" * LIST (\Noselect \HasChildren) "." "#shared.doveimap" * LIST (\HasNoChildren) "." "#shared.doveimap.Common" x OK List completed. x lsub "" * * LSUB () "."

"#shared.doveimap.Private" x OK Lsub completed. x logout Is this the way it's supposed to work ? My setup is : namespace { type = shared separator = "." prefix = "#shared.%%u." location = maildir:/courriel/boites/%%u:INDEX=/var/dovecot-2/indexes/%1u/%u/shared/%%u:CONTROL=/courriel/meta/%%u # Use the default namespace for saving subscriptions. # subscriptions = no # hidden = no # list = no list = children } # pwd /courriel/boites/doveimap # cat dovecot-acl-list 1294755382 Common # cat .Common/dovecot-acl user=dovepop akxeilprwts # cat .Private/dovecot-acl cat: .Private/dovecot-acl: No such file or directory Also, I'm not sure I correctly understand what "Use the default namespace for saving subscriptions." option is. Is it just the location of the subscription file for mailboxes subscribed in the shared namespace ? Where would it be if set to "yes" ?

[Dovecot] dovecot lda and quota plugin with mysql

Dear all, I have postfix delivering to dovecot lda (via spamassinassin). I have configured the quota plugin, but it does not seem to respect the details in the quota table in mysql.

Hi, I have a user called archive that gets a BCC of all incoming/outgoing email. I would like to have the email in the new/cur directories setup to be read only, is there a way to do this in dovecot 2.0.8. I know you can set the umask in the dovecot config but I believe this is a global setting. Thanks, Paul

[Dovecot] Rename public folders
by Burian, John 16 Jan '11

16 Jan '11

I've got a number of public mailboxes configured for my users. We pretty much have to use Entourage for a client, which insists on creating all new subfolders with the name 'Untitled Folder'. When they try to rename these subfolders with useful names, Dovecot returns A028 NO [CANNOT] Renaming not supported across non-private namespaces. I guess this is because renaming a subfolder could potentially break subscriptions for other users? Or is it a hard requirement from IMAP RFC? If the former, is the problem merely very complicated, but eventually fixable, or is it just intractable? We're using Dovecot 2.0.7 from the atrpms RPM, Redhat EL 5.0. The public mailbox namespace is configured with: namespace { type = public prefix = Public/ separator = / hidden = no list = yes inbox = no subscriptions = no location = maildir:/data/imapmail/public:LAYOUT=fs } -- John Burian Systems Programmer Battelle Center for Mathematical Medicine The Research Institute At Nationwide Children's Hospital 614-355-5686 John.burian(a)nationwidechildrens.org ----------------------------------------- Confidentiality Notice: The following mail message, including any attachments, is for the sole use of the intended recipient(s) and may contain confidential and privileged information.
