[Dovecot] Two-phase delete/expunge ?
by Jan-Piet Mens 16 Dec '05

16 Dec '05

Is it possible to have messages which have been marked for deletion or which are to be expunged, moved into a "secret" directory on the IMAP server? The IMAP client would consider the message as deleted, but an administrator could easily restore single messages (without having to retrieve tapes) by moving the message back into inbox. I understand there are patches floating around somewhere enabling that for Cyrus, but I'd love to see Dovecot do that as well. Is anyone aware of such functionality? Thanks, -JP

[Dovecot] strange connection NG
by Yi Xuan 16 Dec '05

16 Dec '05

Dear all, I have a devocot server based on fedora core 3 in Japan. When my users are in Japan, there is no any problem reported.Devocot works very well. But when my users are in China, sometimes the following problem occured. Sometimes the user can not download mails, after that all connections attempt to server(e.g http/ssh) failed. the user has to close OutLook, and wait for about 10 minutes, then access the webmail to read mail. Maybe the POP NG is due to the network , but what is the possible reason of 10-minute other connection NG? Is there any solution? Because users in China share the same outside IP, when one user occures POP NG, all users occures server access NG, that is a big puzzle. Thanks in advance. Best regards,

[Dovecot] Patch: ioloop using kqueue/kevent for FreeBSD
by Vaclav Haisman 16 Dec '05

16 Dec '05

Hi, I would like to submit the attached patch. It implements IO loop using FreeBSD's kqueue/kevent syscalls. It is based on snapshot of CVS HEAD as of 2005-12-12. I could only give it limited testing on FreeBSD 5.4 but it works fine so far. Vaclav Haisman

[Dovecot] 1.0alpha5 released
by Timo Sirainen 16 Dec '05

16 Dec '05

We have now some new big features: - Beginnings of dbox mailbox format. It should work, but if you happen to delete/break index files, the mails aren't found again. So really not a good idea to use it for more than testing. - GSSAPI (Kerberos 5) support by Jelmer Vernooij with some fixes by pod(a)herald.ox.ac.uk - Added dictionary API to Dovecot, similar to what Postfix has. It can be used for getting/setting key=value pairs, which can be useful for many different purposes. For example it could be used to store mailbox metadata for ANNOTATEMORE extension. Implemented SQL backend for it. In future there should be berkeley DB backend at least. Also there could be some kind of proxy backend which would use UNIX socket to connect to dictionary server doing the actual work. This way each imap/lda process wouldn't have to connect to SQL server themself. - Quota plugin is now included. We also have now dictionary based quota support, which means the quota limits and values can be stored in SQL. However I haven't actually tested these changes yet, so there's a good chance the quota plugin doesn't actually work at all. - Created a new trash plugin which works only together with quota plugin. The point of it is to expunge mails from a list of configurable mailboxes whenever saving new mails would cause the account to go over quota. The oldest mails are expunged first, and only as many mails are expunged as is needed to save the new mail. For configuration it first looks up for ~/.dovecot.trash.conf, and then fallbacks to /etc/dovecot-trash.conf. The file format is "<priority> <mailbox name>". It's possible to have multiple mailboxes with same priority. Lower number = higher priority. This plugin is also currently untested. The plugins are currently installed as shared libraries to plugin directory. At some point I'll add a configure option to select which plugins to compile directly into binaries. Possibly even do it by default for some plugins (quota). And smaller new features: - If LDAP lookup fails because connection gets closed, try retrying it again after reconnect. This is however untested, hopefully didn't break LDAP code completely.. - %w variable in dovecot-auth contains password. Can be used to do eg.: password_query = select null as password from users where userid = '%u' and password = password('%w') - syslog_facility setting And fixes: - auth_cache was quite broken - adding keywords caused sometimes assert-crash - If login_greeting_capability = yes we could have sent the capability before dovecot-auth returned what auth mechanisms were available, forcing clients to use plaintext authentication - Lots of mbox fixes again.. - userdb prefetch wasn't supposed to be uncommented in dovecot-example.conf in alpha4. Comment it out if you don't need it. - Don't crash with "out of memory" in 64bit systems - IDLE command might have crashed when finishing itself if there were lots of external changes - pop3_reuse_xuidl setting wasn't actually working

[Dovecot] Logging IMAP deletions
by Jan-Piet Mens 16 Dec '05

16 Dec '05

I'm using dovecot-1.0.alpha5 and I'd like to be able to log the fact that a message has been deleted (or marked for deletion) in order to prove to end-users that they actually deleted a message. Is that possible? -JP

[Dovecot] messages_count too large (1121 > 1115)
by Moritz Willers 16 Dec '05

16 Dec '05

I've seen this was mentioned before but remains unsolved. I upgraded Dovecot from 0.99 to v1.0.alpha4 yesterday and it rendered my inbox inaccessible: Dec 15 00:09:07 sand dovecot: imap(willers): Corrupted index file /home/willers/mail/.imap/INBOX/dovecot.index: messages_count too large (1121 > 1115) I've since moved that inbox away so I can view my new mail again. The error has moved with the mbox file: Dec 15 00:27:41 sand dovecot: imap(willers): Corrupted index file /home/willers/mail/old-inbox/.imap/200407-200512/dovecot.index: messages_count too large (1121 > 1115) Dec 15 00:27:41 sand dovecot: child 83886 (imap) killed with signal 11 This is on FreeBSD 4.8 (yes, yes ... but: "up 687 days" which is quite nice) all running on local disk. So earlier suspicions about NFS or MacOS X are out of the window. One day I'll move move from mbox to dir format and the problem will go away, in the meanwhile, I thought it would be good to resolve this issue. Let me know how I can help to get to the bottom of this. - mo

[Dovecot] Best way to upgrade from 1.0a4 to 1.0a5
by Cliff Hayes 16 Dec '05

Hello all, I have 1.0 Alpha 4. Is it better to shut down sendmail, uninstall dovecot 1.0a4 then install 1.0a5, or just install 1.0a5 over the top of 1.0a4? Thanks, Cliff

[Dovecot] Variable '%r' doesn't transfomr in Postgres query
by Sebastjan Trepca 15 Dec '05

15 Dec '05

Hi, i'm using postgres for authorization. When I switched from a4 to a5 authorization stoped working. Query in conf file for postgres looks like this: password_query = select password from auth('%u','%r'); But in logs, the transformed query looks like this: Performing query: select password from auth('test','%r'); Looks like you don't transform that remote IP parameter?

[Dovecot] writing an MDA, help me avoid corrupted indexes
by Lee Howard 15 Dec '05

15 Dec '05

Hello. First, I want to thank those responsible for Dovecot IMAP as it was a real treat to implement in comparison to my mostly-failed attempts with Cyrus. The passwd-file authentication was exactly what I needed as I really didn't want to have to deal with PAM or LDAP but where I am setting up a server with virtual accounts. I'm using Postfix as an MTA, and it quite handily passes the mail off to SpamAssassin. From there I need an MDA to dump any mails detected as spam into a common spam folder, discard any mails with viruses (antivir) and send a notification to me, and then drop good mail into the appropriate maildir directory for the virtual users to get via both POP3 and IMAP. I could conceivably use procmail to do that MDA, and I've done similar things with procmail in the past, but my growing experience with procmail indicates that procmail is too ferocious for what simple work I need done, and too difficult to make work right in a virtual-user environment. So I've written my own little MDA with a few lines of shell that will take the mail from Postfix+SpamAssassin and ultimately deposit mails in the maildirs. So far so good, except that I keep seeing corrupt indexes... probably because I'm not touching the indexes at all with the MDA. My guess is that in order for the MDA to properly deal with maildir it needs to adjust the indexes after depositing new mail. Okay. So can someone either give me a pointer to the proper documentation on this, including the index file formats, or perhaps just explain it to me? Maybe I'm missing a larger picture of maildir handling? I've glanced through http://www.dovecot.org/doc/index.txt but I notice that the index files are not ASCII, so I'm not sure where to start at understanding that documentation. Any and all help would be appreciated. Thanks, Lee.

[Dovecot] How to serve two "inboxes" via imap
by Roderick Johnstone 15 Dec '05

15 Dec '05

Hi In our setup we have mail delivered to /var/spool/mail/<username>. Many users like thunderbird as their MUA and we typically have thunderbird set up to read mail using a movemail account with the local mail directory set to ~/mail so that the mail can be read easily by pine as well. So, when a user clicks the "Get Mail" button in Thunderbird, mail is moved from /var/spool/mail/<username> to ~/mail/Inbox. Although I can serve other folders from ~/mail my imap clients don't see ~/mail/Inbox, they see just /var/spool/mail/<username> as INBOX. Can anyone advise please how to make the ~/mail/Inbox available as well via imap using dovecot (currently using 1.0-alpha5). We currently use default_mail_env = mbox:~/mail/:INBOX=/var/spool/mail/%u Many thanks Roderick Johnstone

[Dovecot] checkpassword authentication
by Florian Füessl 14 Dec '05

14 Dec '05

Hi, does anyone already use the checkpassword authentication scheme? I have not found any description how I have to configure dovecot in order to work together with qmails checkpassword. Enabling passdb = checkpassword /bin/checkpassword in dovecot.conf starts /bin/checkpassword for every authentication request, but the result does not seem to matter for the authentication. Without enabling a userdb entry, dovecot claims not to be able to find out the uid, gid and home of the user, although checkpassword replies these values. Setting static values with "userdb = static uid=$fixed_mail_uid gid=$fixed_mail_gid home=/maildata/%d/%n" results in being every login successful, no matter if the checkpassword authentication is ok, or not. I'm using the latest dovecot nightly build from 22. Nov. 2005. - Florian

Hi, dovecot (1.0.alpha5) won't compile with inotify support because inotify.h can't be found. I'm running Linux 2.6.15-rc5 with headers from 2.6.12 (like most vendors). I've noticed that beagle and other inotify-enabled applications ships with an inotify.h. Could this be scheduled for alpha6? :-)

I'm trying to switch to imap from pop3, so I set up dovecot on my Slackware 10.2 mailserver. I'm very new to imap, so I figured my configuration was wrong. If our symptoms are the same, maybe our setup errors are as well. The problem... while Thunderbird and Outlook are OK, the Inbox doesn't show in Outlook Express. You can click on the Imap Folders button, select the Inbox, click on the "Go To" button and the Inbox will appear until you shut down Outlook Express. Next time you fire up OE, no Inbox. Other than that, it all works as expected. I haven't torture-tested the setup yet though, I wanted to set up one of each client and get the basics running before doing that. Are your symptoms similar? Here is my dovecot.conf less comments... ssl_cert_file = /etc/mail/certs/wally.cert.pem ssl_key_file = /etc/mail/certs/wally.key.pem first_valid_gid = 100 mail_extra_groups = "mail" namespace private { separator = / inbox = yes prefix = "#mbox/" location = mbox:/var/spool/mail/%u } namespace private { separator = / prefix = location = maildir:/data/imap/%u } protocol imap { imap_client_workarounds = outlook-idle } protocol pop3 { } auth_realms = "laframboise.net" auth default { mechanisms = plain passdb shadow { } userdb passwd { } userdb prefetch { } user = root }

[Dovecot] mailserver pop3-login: Disconnected
by Shawn Bishop 13 Dec '05

13 Dec '05

Good Day I am having the following serious problem. I am running CentOS 4.1 with dovecot 0.99.11. The users are using POP3 login to retrieve mail. For the last 2 days we have experienced the following problems. I have recreated all the users and reconfigured the dovecot,but the same problems occur. Please see attached /var/log/maillog messages It appears so users login whereas others cant.Eventually after about an hour none of the users can login.

[Dovecot] Case sensitive nightmare
by Erik Petersen 12 Dec '05

12 Dec '05

It took me 4 days to figure this out and I sure hope someone can help me solve it. My Setup: Postfix + MySQL + dovecot dovecot.conf: default_mail_env = maildir:/var/spool/vmail/%d/%n/Maildir password_query = SELECT password FROM mailbox WHERE username='%u' user_query = SELECT maildir, 108 AS uid, 108 AS gid FROM mailbox WHERE username='%u' The virtual host schema is postfix.admin compatible but I¹m not using it (phpMyAdmin is actually easier to use). When foo(a)domain.tld, abrand new account, logs in using an IMAP client (any client; squirrelmail, OE, tbird, Apple...) a maildir is created named domain.tld/foo/Maildir¹ and everything is good. Now I login as Foo(a)domain.tld and then as fOo(a)domain.tld and then as foO(a)domain.tld then so on for every case variation. Each of these accounts can login correctly, they are seen as being the same account by dovecot. On the other hand they are not seen as being the same mailbox! When I check my mail spool I see one maildir for every case variation (domain.tld/foo/Maildir, domain.tld/FOO/Maildir, etc.) It would seem to me that the queries above would fail for the different variations of the name but they don¹t seem to. Is dovecot converting %u to lower case for the query on the virtual users table but then using it unconverted when looking up the Mairdir for the account? If the username column has the value foo(a)domain.tld1 how does SELECT * FROM table WHERE username=¹FOO(a)domain.tld1 match the row? Also puzzling is that I select a column named maildir which has the path to the mailbox in it (using the correct case). Even if SELECT pigs fly¹ AS when WHERE FoO¹=¹foo¹ the maildir path for the account is being returned which is domain.tld/foo/Maildir¹ so how does domain.tld/FoO/Maildir¹ get created? This is both a pain in the nuts support nightmare but also a security problem (albeit fairly limited). An account named ³barneyrubble² could generate a significant number of maildir directories if you logged in with every variation thereof. Any assistance would be greatly appreciated. Thanks

[Dovecot] configuring squirrelmail with tls for both imap & smtp on FC3 with dovecot & postfix

hey friends, I am trying to secure my mail server.I have enabled TLS support in postfix(version postfix-2.1.5), now I am trying to configure squirrelmail(version 1.4.4-1 rpm) for tls/ssl support.In config.php i have choosen use_imap_tls=true and use_smpt_tls=true.

[Dovecot] Corrupted index problem when disk quota exceeded
by Sergey Redin 11 Dec '05

11 Dec '05

Hi! I should report yet another problem with dovecot index files. Suppose we have a user with his filesystem disk quota exceeded. He logins via POP3 or IMAP to remove some mail messages and fix this problem. When he logins for the first time, everything works fine, and he can read and remove something. But if his disk quota is still exceeded when he logs out, he cannot login any more. I guess it is not fair to give user only one chance to clean his mail folders :) The problem is that dovecot tries to rewrite index files on logout, but it cannot do it correctly because the user's filesystem quota is exceeded. So the next time dovecot just replies "Mailbox is in inconsistent state, please relogin". I believe that dovecot should work with any kind of corrupted index files, this is why I report such kind of bugs here. Here is a sample session with dovecot which shows the problem: ======================================== dovtest# telnet localhost pop3 Trying ::1... Trying 127.0.0.1... Connected to localhost.

[Dovecot] Feature request: Dynamic user lookup modules

Hi, As a packager I'd think it would be way cool if the lookup modules that needs to link against external librarires (ldap, pgsql and mysql) could be loaded dynamically at run-time. Am I alone on this? :-)

[Dovecot] openssl > 0.9.f-4 a must for dovecot 0.99.14 ??
by Adrian Mak 10 Dec '05

10 Dec '05

My linux is Redhat AS3 U3, openssl is 0.9.7a-33 I downloaded dovecot 0.99.14 src rpm and rebuild to binary rpm Everything went smooth but I tried to install the dovecot binary rpm, it reported that openssl need >= 0.9.7f-4 Since there are many other rpm packages have dependency on the current version of openssl 0.9.7a-33, so It's not possible to upgrade openssl to 0.9.7f-4 or greater Is it a must to use openssl 0.9.7f-4 or greater in order to use dovecot 0.99.14 ?

[Dovecot] Order of emails
by Marcus Don 10 Dec '05

10 Dec '05

Hi We have an issue regarding the order in which emails are displayed in an imap folder, which our customers regularly complain about. By default, emails are returned from a folder in the order in which they were placed into the folder, which makes perfect sense. However, if an email is moved into another folder, it will always appear at the top, no matter how old it is. We could order the emails ourselves before displaying them in our webmail program. However, this would mean parsing the headers of every single email, which could be many thousands, so would slow things down considerably and greatly increase load. At the moment, we only read 30 at a time as the user pages through the folder. >From what I can see, the order is determined by the timestamp in the email filename, which gets updated every time the email is moved. Is there any way we could disable this, so the filename (or at least the timestamp part of it) remains constant? If so, would this affect in any way the behaviour of other imap clients, such as Outlook? All suggestions welcome.

[Dovecot] Squirrelmail/dovecot sort problem/bug
by A.P.Munnikes 10 Dec '05

10 Dec '05

Hello, there is a little bug in Squirrelmail 1.4.5 or Dovecot 1.0.alpha4-1: the sort is not correct if I use squirrelmail with the option: 10. Allow server thread sort : true 11. Allow server-side sorting : true with the option on false and with Thunderbird 1.5rc1 there is no problem, but I think Thunderbird 1.5rc1 already does the sort by itself. I have a folder with 1054 messages, but if I sort (from old to new) them in squirrelmail the newest 3 messages (received after the migration from thunderbird/pop3 to dovecot) are on the first page, before the messages from 5 month ago. 14:08 3.4 k (that is today 8 dec, 2005 ) 08:26 5.2 k + 00:07 2.9 k 8 jul, 2005 4.1 k 6 jul, 2005 3.5 k 3 jul, 2005 3.1 k 8 jul, 2005 4.1 k 6 jul, 2005 3.3 k 8 jul, 2005 3.8 k 5 jul, 2005 4 k 8 jul, 2005 7.4 k 11 jul, 2005 6.8 k Also my 'sent' folder: sorted from new to old contains on the last page 2 messaged that I send today (after the migration to dovecot) 12 jan, 2005 2.8 k 12 jan, 2005 1.7 k 11 jan, 2005 1.5 k 10 jan, 2005 1.1 k 8 dec, 2005 1.1 k ( <= send from thunderbird) 8 dec, 2005 1.6 k ( <= send from squirrelmail) And also an other mail folder has sorting problems. However my INBOX looks normal, while I received 5 or 6 messages after the migration.

[Dovecot] Update on Using Dovecot with Webmin
by Lee MSN 10 Dec '05

10 Dec '05

First of all thanks for the replies. I have decided to try the updated version 1.0 alpha After uninstalling Dovecot .99 and cleaning up user,groups and files. (Dovecot .99 was authenticating as best I can tell using unix users = the default -- and PAM = the default - I only had to setup the PAM if I remember correctly. Loaded Dovecot 1.0, made sure user, folders and files all seem to be setup correctly. Now - Webmin is able to stop and start Dovecot and it loads fine on reboot. But, it is pretty obvious that the Webmin modual is not up with then new and much more powerful Dovecot config file. For me that is OK, as long it will show weather the service is up or down - stop and start it, which is seems to be doing just fine. The reason I say this is when I try and use the Webmin modual to set user authentication to Standard Unix user database and PAM - it does not work. So I am needing help editing the Dovecot.conf file. My new problem is this: Can not get users to authenticate. I am trying to first setup just unix authentication - with plain text for starters then will move up to more secure. I have left the config file default - just made changes until it would start. With the notable execption I set plain text to yes. I have setup the Dovecot PAM file per the documentation. So what I need help now with is this I am wanting to setup a very simple setup to start with: A setup so that a outlook express client can login, using plain text password, unix login and password POP3 = yes Users = linux/unix (/etc/passwd) Passwords = PAM or Shadow Can anyone send me and edited config file that is setup to for this type of authentication? Or cut from their config file those sections needed for the authentication? Actually, if anyone is willing to share a config file that is setup with a more secure type of authentication that would be great too. (Thinking of switching to Cyrus - have any of you jump off of Cyrus to use Dovecot -- why??)

[Dovecot] Dovecot out of memory errors on Debian sid
by Ric 10 Dec '05

10 Dec '05

hi I have dovecot (1.0.alpha4-1) installed on a Debian sid amd64 machine (dovecot-imapd and dovecot-common). I am using this so that I can use both Mutt and something like Thunderbird to access my local Maildir folders. Sometimes it works fine. Sometimes when I try to access my mailboxes locally using Mutt, it hangs for a very long time (the bottom of the screen says "Selecting in..." (.in is the mailbox), and eventually gives me a blank mailbox with "(no mailbox)" at the bottom of the screen. In /var/log/mail.err I find lines like the following: Dec 3 06:39:02 localhost dovecot: child 4600 (imap) returned error 83 (Out of memory) Dec 3 06:44:03 localhost dovecot: imap(ric): pool_system_malloc(): Out of memory For example, it was working fine earlier this morning, but now I am unable to access the mailboxes and I'm getting the error messages in /var/log/mail.err. I have the same problem with Thunderbird; it hangs and cannot access the mailboxes. At my office I have dovecot (0.99.14-1) installed on a Debian sarge machine and it works fine. I would appreciate any suggestions as to what to try or what to look for. My dovecot.conf file is very simple: ## Dovecot 1.0 configuration file protocols = imap listen = localhost ssl_disable = yes log_timestamp = "%Y-%m-%d %H:%M:%S " mail_extra_groups = mail protocol imap { } protocol pop3 { } auth default { mechanisms = plain passdb pam { } userdb passwd { } userdb prefetch { } user = root } Thanks, Ric

[Dovecot] "Out of memory" error in 1.0alpha3
by Sergey A. Lipnevich 10 Dec '05

10 Dec '05

Hi All, I have Dovecot 1.0 Alpha3 running on x86_64 Linux 2.6 multi-CPU box using Maildir folders. Moving messages from one folder to another in Thunderbird 1.0.7, regardless of their size (usually small), produced error 83, "Out of memory", when both of these parameters were unset (default): mail_read_mmaped, mmap_disable. The log line before the error was pool_system_malloc(): Out of memory. I initially changed mmap_disable to "yes", the error stopped, but it still wasn't moving messages reliably. I then set MM parameters more aggressively: mail_read_mmaped = yes, mmap_disable = no (and the third of the series, mmap_no_write, is left unset). The error stopped popping up, and the moving works speedily. Maybe the default for mail_read_mmaped should be "yes?" Thank you! Sergey.

[Dovecot] yet another update of the Dovecot AUTH patch: 20051208
by /dev/rob0 09 Dec '05

09 Dec '05

Wietse won't sit still ... removal of the lmtp(8) client broke the previous issue of the revised Dovecot AUTH patch. So I just redid it for the 20051208 snapshot: http://www.nodns4.us/postfix-2.3-20051208-dovecot-auth.patch.gz $ md5sum *gz ; ls -l $_ 32946afa424b3fbc04c8d9822e711e1f postfix-2.3-20051208-dovecot.patch.gz -rw-r--r-- 1 rob0 console 7287 2005-12-09 17:09 postfix-2.3-20051208-dovecot.patch.gz The original patch is here: http://dovecot.org/patches/postfix/postfix-2.2.1-dovecot-auth.patch Instructions are here (and don't forget the Postfix SASL_README too): http://dovecot.org/patches/postfix/README NB: Although my own postfix-2.3-20051208 snapshot compiled with the patch and is running, it is not tested at all. I'll try with AUTH later and see if it's working. I will not be able to test with LMTP. IIUC how this patch affects LMTP, it's only in that the USE_SASL_AUTH flag was changed to USE_SASL_CLIENT_AUTH. So the only people affected would be ones who are using Cyrus-SASL for client AUTH. Please let me know via either list (or offlist, see .sig) if you use this and have any problems. -- mail to this address is discarded unless "/dev/rob0" or "not-spam" is in Subject: header

[Dovecot] Controlling Dovecot with Webmin
by Lee MSN 08 Dec '05

08 Dec '05

Dear Sir I have just setup a Fedora 4SE server, with Webmin - latest production release and Dovecot .99.14. The only way to start dovecot is to be logged into the server as root - locally or ssh, and type the dovecot command. >From Webmin - logged in as ROOT, when I attempt to start Dovecot it tells me that it can't because it can not open the config file - permission denied. This indicates to me that Webmin is not really logged in a "root" but that doesn't seem right since I use root/password when I access the server per the Webmin instructions. Also, in the Webmin configuration for that server - it references a master.pid file. Which did not exist. I tried to create a pid file using the PID (19638) of the Dovecot service. That did not help the start up problem, but I am sure needs to be fixed before I can have the service start on boot up?? I got the PID number after starting Dovecot and then going and seeing the services that where then running. The user/group Dovecot where created during the install. Sendmail is running along with SpamAssassign. When I start Dovecot, logged in as root at shell, everything runs well, email is processed all the way through. Do you know how to resolve this problem of controlling Dovecot through Webmin and making sure the Dovecot will start on reboot of the server. Thank you very much. Lee D. I am new to setting up linux servers like this. _________________________________________________________________ Express yourself instantly with MSN Messenger!

[Dovecot] Dovecot login hangs often
by P P Anwar 08 Dec '05

08 Dec '05

Hi - We have dovecot version : 0.99.11 release : 2.EL4.1 on Centos 4.2, with an LDAP backend (Samba PDC) and pam set to authenticate against LDAP. Dovecot is set to use pam for authentication. It uses mbox, and the machine has very little load (95% idle, no memory pressure). Every 36 hours or so, no users are able to login to imap (we have only imap enabled). Other services that use the same backend are working fine (like squid and ssh logins) even while this is happening. So we are not sure if we can blame this on pam/ldap problems. When this happens, we tried a "service dovecot restart", and that results in saying the "address is in use". About 10 "imap-login" processes seem to lurk around holding on to the imap port. We can get dovecot service to start again, only after a "killall -9 imap-login". What kind of debug should we enable so that you all can diagnose this further ? Any other configuration things that we should try ? We prefer to stay with Redhat/Centos releases, but if this is already reportedly fixed in one of the later builds, we are open to trying one. Regards, Anwar.

[Dovecot] Re: corrupt attachments
by Brian Thompson 08 Dec '05

08 Dec '05

Hello all, any suggestions on this? It seems like a pretty serious issue and it hasn't reoccurred since we switched back to UW imapd. As I mentioned, it seems to be related to dovecot compiled on Solaris 10/x86... The same code compiled on Solaris 8/sparc seemed to work well. -Brian Brian Thompson wrote: > > Not sure if this has already been covered, but any pointers > or suggestions would be greatly appreciated. > > We just realized last night that dovecot-stable seems to be > corrupting the attachments within users' inboxes. > > In an attempt to resolve the problem, we upgraded the > mail server here to Dovecot 1.0alpha4 but it didn't help. > > To the best of our knowledge we didn't start experiencing > this phenomena until we migrated from Solaris 8/Sparc > to Solaris 10/x86 about 3 weeks ago. > > To be more specific: > A non-corrupt attachment can be sitting within a user's > mail spool (mbox format) and live there without a problem > until an imap client goes to download the attachment via > dovecot. > > At that time, dovecot seems to be stripping the last four > characters from each base64 encoded ascii line within the > attachment and rewriting the message within the mail spool > without those characters.

[Dovecot] "pop before smtp" dovecot.conf
by Jean-Marc Pigeon 07 Dec '05

07 Dec '05

Bonjour a Tous, I would like to generate (on the fly) a list "popbeforesmtp" when dovecot POP/IMAP authentication succeed. Intended Format will/should be such as: 'timestamp_in_second' user_id remote_ip one user per line. My guess we have all the needed information within dovecot to make such list. But I have seen no way to 'trick' dovecot (dovecot-1.0.alpha3) to do it... Could someone on the list able to give me some advices? I know there is Perl script to scan maillog file and extract information from collected data, but this seem to me 'a kind of the very last option'.... May be the trick can be achieved using 'executable' function? Ideally I'll like to have an entry in dovecot.conf, like... popbeforesmtp=/somewhere/in/the/tree A bientot -- ========================================================================== Jean-Marc Pigeon Internet: Jean-Marc.Pigeon(a)safe.ca SAFE Inc.

[Dovecot] Pop-before-smtp and MySQL?
by Matteo Garofano 07 Dec '05

07 Dec '05

Hi, I found that dovecot have many nice features. Now I write because I'm tring to setup the dovecot server, I would substitute a qpopper daemon (patched for mysql authentication) The problem I find is to set up the pop-before-smtp using sql (mysq) as written in http://wiki.dovecot.org/moin.cgi/PopBSMTPAndDovecot (Waiting for post_login ;-) I would use the script popbsmtp.sh and not a perl pig. (I'm using qpopper patched to store the relay IP in mysql and it works) I set .my.cnf in /root What happen is that the $3 don't contain the IP that should be written to the DB. Is there something I miss ? I tried to modify the dovecot.conf file like this mail_executable = /usr/local/libexec/dovecot/popbsmtp.sh /usr/local/libexec/dovecot/pop3 %r "%r" and it write to the db the litteral value %r and not the ip, otherwise it write nothing. the connection with mysql works and any other operation on it works. this should be the last step for my setting. Have you any hint? Thanks in advance and best regards Matteo Garofano

[Dovecot] Tools to analyze status/stats?
by wolff 07 Dec '05

07 Dec '05

Hello, I recently installed dovecot on a server running Debian. I only have 10 users, but we probably have 6Gig of email between us. Things were working flawlessly for a couple of weeks, and I'm still getting email, but the last few days we are getting fewer emails that we typically do. So although things seem to be working well, everyone is suspicious something is wrong due to the lack of email volume. Is there a size limit that dovecot can manage? Are there any admin tools to get status messages for dovecot? Are there any reporting tools to show how many messages are processed/managed by dovecot? Thanks!!

[Dovecot] 1.0alpha4: pop3_reuse_xuidl patch
by grant beattie 06 Dec '05

06 Dec '05

hi all, this is needed to make the pop3_reuse_xuidl option work in 1.0alpha4. I am using maildir and I noticed that for each message which doesn't have an indexed X-UIDL header, the entire message is read from disk. as this is reading only headers, it is probably reasonable to stop reading at the end of the headers. it would also be neat if dovecot could be configured to only try reading X-UIDL headers from messages if the mailbox indexes don't exist, since I guess it would be common to want to preserve existing X-UIDLs but not bother for new messages (perhaps some mtime comparison, or something). opinions? I haven't looked at the source enough yet to be able to do this, but these two optimizations would vastly reduce the amount of disk IO as a result of using this option. grant.

[Dovecot] Struggling with namespaces...
by Kev Latimer 06 Dec '05

06 Dec '05

Hi all, I've been using dovecot 0.99x as a basic POP3/IMAP server at a couple of sites for a few months now and am very happy with it's simplicity, stability and performance, especially over the rather 'clunky' courier and the mammoth cyrus. I'm building up a top level mail server for our organisation and am desperate to use dovecot in there but I'm really struggling with using namespaces to create some shared maildirs - note that in this case I'm using the 1.0alpha4 debian packages that recently made it into 'etch'. I have very simple requirements here - I just want to be able to have some common folders subscribable by certain users, for my testing an announcements folder accessible by all and an archive folder I want to place some restrictions on. Whenever someone needs access to someone elses folder (ie. holiday watch), symlinking should be sufficient. I can start up dovecot, log in as a user (I authenticate against LDAP btw), see the directories specified in my namespace directives be created but I can't subscribe to anything. Squirrelmail gives an error stating "[TRYCREATE] Mailbox doesn't exist: archives" while Thunderbird shows the folder names in grey and refuses to subscribe. Am I missing the point of namespaces or have I failed to create something in the folders to get them to play? I read something about a dovecot-shared file but I think this is a 0.99 thing, although I tried creating the file with the permissions I wanted applied to the folder and it didn't do anything... I did notice that when the folders are created, they are created owned by the first user logged in. I have tried chmod'ing them to 777 to see if it makes a difference, but alas, no. The relevant bit of dovecot.conf is: namespace private { separator = / #prefix = #location = inbox = yes #hidden = yes } namespace public { separator = / prefix = announcements/ location = maildir:/var/mail/announcements/Maildir } namespace shared { separator = / prefix = archives/ location = maildir:/var/mail/archives/Maildir } I'm sure I'm just being picky, but a better explanation of namespaces in the docs might be in order, maybe with some examples. If I get this sussed out, I'll put one in the wiki ;) Any help much appreciated! Kev

[Dovecot] 1.0.alpha4 process creation wierdness
by Mark Rosenstand 06 Dec '05

06 Dec '05

Hi list! I'm a little confused. I have set "login_process_per_connection = yes" and "login_processes_count = 1", and this is how my pstree looks when nobody is connected: dovecot -,- dovecot-auth `- imap-login However, when I connect with a client it looks like this: dovecot -,- dovecot-auth |- imap `- 2*[imap-login] I would expect it to only have one imap-login running. Anyway, when I disconnect the client, the imap process exits but imap-login keeps running: dovecot -,- dovecot-auth `- 2*[imap-login] This is when it gets really wierd. When I connect a client again, my pstree looks like I would have expected it to on my first connect: dovecot -,- dovecot-auth |- imap `- imap-login If I re-connect, we start over again (i.e. dovecot-auth, imap, 2 * imap-login). Anybody got a clue what's going on? :-) -- .-. Mark Rosenstand (-.) oo| cc ) /`'\ (+45) 255 31337 3-n-( (\_;/) mark(a)borkware.net _(|/`->

[Dovecot] Feature/bug starting from xinetd
by Geoffrey S. Mendelson 06 Dec '05

06 Dec '05

Hi, I hate to have my first post be a bug, but this drove me crazy for a while. I compiled the latest version from source and followed the instalation instructions. I then copied the xinetd.d entries from the Wiki and proceded to test. No matter what I did I could not log on. I found that while I was editing /usr/local/etc/dovecot.conf, nothing was hapening. I then started it manualy and found several errors in my editing. :-) After fixing the errors and getting it to work properly, I went back to running it from xinetd. It would not allow me to log on, nor would it use any of the loging options I set. After making a symlink from /usr/local/etc/dovecot.conf to /etc/dovecot.conf, it worked perfectly. My suggestions: 1. Change the Wiki to point out the difference in the config file location. 2. Change the inetd version to default to /usr/local/etc. 3. Add (and/or document) an option to the inetd version to specify config file location. Thanks, Geoff. ( A very happy Dovecot user, thanks for a good product). -- Geoffrey S.

[Dovecot] New Install Assistance
by Cliff Hayes 06 Dec '05

06 Dec '05

Hello, I built a Fedora 4 sendmail server to replace our old one. I wanted to try the stock Dovecot popper (we currently use pop3d). I tried implementing Dovecot this morning and failed. All I want to use is the POP portion (no IMAP). From what I could find on the Internet, all I had to do is change dovecot.conf protocols line to read like this: protocols = pop3 Apparently, that wasn't enough. Here are the errors I saw in maillog: Oct 31 07:54:23 sendmail dovecot: child 25511 (pop3) returned error 89 Oct 31 07:54:24 sendmail pop3(cliffhayes): mbox: Can't create root IMAP folder /home/cliffhayes/mail: Permission denied Oct 31 07:54:24 sendmail pop3(cliffhayes): MAIL environment missing and autodetection failed (home /home/cliffhayes) Now, I did find out that I had a permissions problem with /var/spool/mail (I had done an SCP of all our users to var/spool/mail on new box). All user mailboxes had root/root as user/group. I know how to fix that for next time, but why is it trying to use a home directory (we don't use those)? And what MAIL environment is missing? Do I need to mess with the following settings: # default_mail_env = maildir:/var/mail/%1u/%u/Maildir # default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u # default_mail_env = mbox:/var/mail/%d/%n/:INDEX=/var/indexes/%d/%n Thanks, Cliff

[Dovecot] Dovecot and loadbalancer
by Cyril Feraudet 06 Dec '05

06 Dec '05

Hi all, I've 4 servers with dovecot and ldap authentication behind a loadbalancer (Alteon). To connect to dovecot, client need to use a vip of the loadbalancer. To connect to the ldap server, dovecot need to use the loadbalancer cause there are several ldap server. The loadbalancer close a connection without activity during 30mn Dovecot lauch several authentication process who have a connection to the ldap server each. Each client (user) have several imap connection to dovecot. I've 2 problemes : - If a client (thunderbird for ex.) don't use a connection during 30mn, the loadbalancer delete this connection from his connection table and the client seem not able to correctly reopen another - If a dovecot authentication proccess want to request ldap but haven't do it in the last 30mn, it fail an say that the authentification fail. Somebody have already use dovecot in a redundent environnement ? Have you an idea to solve these problems Thanks, Cyril Feraudet

[Dovecot] New mailbox format
by Timo Sirainen 06 Dec '05

06 Dec '05

I've been doing some thinking on a new better mailbox format that'd be faster than mbox and maildir for most common uses. Comments welcome. It won't come to Dovecot v1.0, but I'll probably create another branch to Dovecot CVS where I'll start implementing it and some other possibly destabilizing changes. Generic ------- The point is to have a mailbox format where the mailbox can consist of one or more files. Grouping multiple files in a single file makes it faster to read, but it's slower to expunge mails from the beginning of the file. So this format would allow sysadmin to specify rules on how large the files would be allowed to grow. This format is mostly designed to work nicely with separate index files such as Dovecot has. The flags are stored in the mailbox files mostly as a backup in case the index gets lost or corrupted. Index File ---------- Named "index". Index file gives a mapping between UIDs <-> filenames: Header: <uidvalidity> <last-used-uid> Record: <uid-first> <uid-last> <filename> Record: .. eg.: 1127468129 5 1 3 msg.1 4 4 msg.4 All of the UIDs don't have to actually exist in the file if they have been expunged. The record should be removed once all of the UIDs have been removed from it (and the file itself been deleted). The same file may appear multiple times in the index. For example: 1 2 msg.1 3 3 msg.3 4 5 msg.1 This means that UIDs 1, 2, 4 and 5 are in file msg.1, but UID 3 is in file msg.3. The filename doesn't matter as long as it's unique, but probably wouldn't hurt to include its first UID in the filename so humans can find mails more easily. The filename however must not end with ".lock". The file is modified by creating first exclusively owned "index.lock" file, updating it and then rename()ing it over the index file. This lock file shouldn't be held for a long time, so if it exists, and it doesn't get modified at all within 30 seconds, it can be overwritten. Before rename()ing over the index file, you should check with stat() that the index.lock file is still the same as you expect it to be (in case your process was temporarily stopped for over 30 secs). The index file's mtime timestamp must grow after each modification. This makes it easy to check if new mail has been added to the mailbox. Mail File --------- File header: Bytes Format Description 8 hex Header size 16 hex Append offset 4 hex Mail header size 4 hex Mail header padding 4 hex Keyword count in mail headers Mail header: Bytes Format Description 8 hex UID 16 hex Mail size 1 1/0 Answered flag 1 1/0 Flagged flag 1 1/0 Deleted flag 1 1/0 Seen flag 1 1/0 Draft flag 1 1/0 Expunged flag n 1/0 Keywords The file layout then goes: <File header> - possible padding due to Header size <Mail header #1> - possible padding due to Mail header size <Mail data #1> - possible padding due to Mail header padding (ie. next Mail header's offset is divisible with Mail header padding) <Mail header #2> etc.. The UIDs must be ascending within the file (but as said above, some UIDs between them may exist in other files). When the file is opened, it must be shared locked with flock(). Expunging mails requires exclusive flock(), so expunges can't happen while someone is still reading the file. Mails can however be marked with expunged-flag, and such mails should be treated as if they are already expunged. Expunged flag must not be removed. If the mail for some reason is wanted to be un-expunged, it must be copied as a new mail with new UID to the mailbox. Modifying flags doesn't require any locks. You'll simply write over those flags you wish to change. That's why each flag takes one byte. Safest way to expunge is to copy all non-expunged mails after the first expunged one to new file. Then update the index file with the new location for the UIDs, and at last ftruncate() at the position of first expunged mail in the original file. Alternative way to expunge is to just move the data over the expunged mails and fruncate() at the end. No index file updates necessary. This is more filesystem quota friendly, but if the expunging gets aborted in the middle it will corrupt the mails. Appending mails can be done by either locking existing file with a dotlock and appending to it, or creating a new file. If appending to existing file, also flock() it so expunging won't happen in the middle of append. If appending to new file, create it with .lock suffix and then check that the file without .lock wasn't already just created. When appending to existing file, check "Append offset" from file's header. If that offset is at the end of file, just append there. Otherwise read the mail's header from there. If it has a non-zero UID and index file says that the same UID exists in this file, jump over the mail and do the same checks for all the rest of the mails in the file. Once the check doesn't match or you reach EOF, update the append offset in the header to that offset and write your mail there. Initially write the UID in mail's header as zeroes ('0', not NUL). Once the append is completely finished, you'll have to update it with the new UID. You'll do this by locking index file, reading the latest last-used-uid and using the next value for your UID. Once you've written it, rewrite the index file with updated last-used-uid field and your UID added to it. After this, update the append offset in the mail file and unlock it. Keywords file ------------- Named "index.keywords". This contains mappings between keyword numbers and names. TODO: may be problematic with lockless flag writes.. Recent file ----------- "index.recent.<uid>" file tells what the last non-recent UID was. The file doesn't have any data inside it. When opening the mailbox you should find and rename() the existing index.recent.<uid> file to the new index.recent.<last-uid>. A successful rename() means the mails between <uid>+1 .. <last-uid> are recent for you. A failed rename() means that someone else managed to do it. You should look for the file again and if it was renamed to less than <last-uid>, you should try again. Nightly cleanups ---------------- Because expunged mails may be left lying around for a while, there probably should be some nightly check that cleans them up. Other cleanups that may be necessary after crashes are: - .lock files - expunged data at the end of files (can be checked with same rules as how appending determines the offset where to append) One problem with nightly expunging is how to expunge mails if the file is still locked by some process. Forced shutdowns may be annoying to users and can be difficult to implement.. Alternative locking strategy ---------------------------- The locking strategy as described above is optimized for high concurrency: Only if mail file is in the middle of being expunged, we're waiting on locks. With appending we may be waiting for existing appends to finish if we don't wish to create a new file for some reason. Other than those, reading and flag updating are completely lockless. The two downsides to this are: 1. flock() isn't available everywhere. It could however be replaced with fcntl() if that's available. NFS may not have either. 2. Expunges can't happen while multiple processes are accessing the mailbox at a same time. This may be a problem if the mailbox never has less than two processes accessing it. The alternative to flock()ing would be to simply handle unexpected end-of-file reads as a sign of expunge, which would require re-reading index file to see where the mails went (or if they were really expunged). This has two problems however. One is that flag writes couldn't catch expunges without locking, and another is that if you've already sent half a mail to IMAP client, you have no other choice than to disconnect the client if you can't send the rest of the mail. It might be worth it optionally. Especially for NFS people. Then you'd basically have the dotlock file that locks appends, expunges and flag updates. Reading would still be lockless. Also for the best performance the mail flags could be stored only in Dovecot's index files. In that case there's no need to update flags and the only downside with this locking strategy would be the potential disconnections, which probably aren't all that bad. Compatibility ------------- If needed, it would be possible to create new/ and tmp/ directories under the mailbox to allow mail deliveries to be in maildir format. The maildir files would be then either just moved or maybe be appended to existing mail files.

[Dovecot] Segfault when using multiple servers
by Marc Maurer 06 Dec '05

06 Dec '05

Should it be possible to run multiple dovecot servers on the same mailboxes (Maildir in my case)? I've a setup where 2 dovecot 0.99.13 servers write to the same mailboxes, which dovecot apparently does not like too much. Example (using imap): - Login with mail client on server1 - Login with webmail on server2 - Delete a mail using webmail on server2 - Hit send/receive in the mail client Result: server1 segfaults. Is such a setup, which is basically a loadbalancing setup, allowed at all by dovecot? Cheers, Marc

[Dovecot] mbox separators ignored
by Kenneth Porter 06 Dec '05

06 Dec '05

Using dovecot-0.99.13-4.FC2 I grabbed a bunch of Mailman archive files from the Weather mailing list here: <http://www.buoy.com/pipermail/weather/> I gunzipped the older ones, then concatenated them all in correct order to create one big mbox file. I dropped it into my ~/mail folder and started my IMAP client (Mulberry) and opened the new Weather folder. It shows one gargantuan concatenated message, instead of lots of more reasonable-sized ones. The messages appear to be properly separated by "<linefeed><linefeed>From<space>". Why doesn't dovecot parse them into separate messages? I double-checked and removed any header lines with Content-Length, X-UID, X-IMAPbase, and X-Keywords. So this should look like a new mbox file with new content delivered by procmail. What's confusing dovecot?

[Dovecot] Virtual domain support using more than one MySQL database
by Dragiša Durić 04 Dec '05

04 Dec '05

For historical reasons I am stuck with situation where hosted domain users have their Mailbox info in mysql enabled vpopmail and our ISP's users have their info in nss_mysql. While I can easily move my users from vpopmail's mysql database to something more "native" to Dovecot, I see no problem to configure Dovecot, as I've already configured Postfix, to use this database directly and access mailboxes without problem. And I would not like to make separate auth database for ISP's users, as I don't like to have two watches when one suffice. Under courier-imap, I've configured my vpopmail domains to authenticate using it's vchkpw module, and mysql was left to me to be configured to use nss_mysql. It works well. Is it possible under Dovecot, and how? Is it possible to to MySQL auth using two different databases? It would be the best. TIA, dd

[Dovecot] Dovecot strange behaviors on Solaris
by Mario Nigrovic-rvvk40 03 Dec '05

03 Dec '05

Folks - I've been using Dovecot for some time now, but have only recently upgraded to 1.0alpha4. I'm struggling to get my configuration right and I'm seeing some truly bizarre issues. My Setup: Solaris 2.8 / Thunderbird / Procmail / Dovecot 1.0alpha4 My mail setup is only for me, so Dovecot runs at an odd port and under my userID. All my mail is in my home directory, which is on NFS (NetApp). The main mail receiver is a different machine which mounts my home directory. Typical entry from .procmailrc: :0 * ^(From|To|CC):.*@.*\<si2.org Maildir/.SI2/ Highlights from dovecot.conf: #default_mail_env = maildir:%h/.mail/Maildir:INDEX=/var/tmp/mario/dovecot default_mail_env = maildir:%h/.mail/Maildir:INDEX=MEMORY mmap_disable = yes #lock_method = flock lock_method = fcntl #lock_method = dotlock protocol imap { listen = *:2143 } auth_worker_max_count = 0 auth default { mechanisms = plain userdb passwd { } } When I run as above (INDEX=MEMORY), I have access to all my mail, but I'm seeing literally thousands of .nfs files created all throughout my .mail/Maildir directories, and Thunderbird periodically locks up. As the filesystem fills with useless .nfs files (I deleted 10000 from ONE mailbox directory this morning), everything gets really, really slow, and I suspect this contributes to Thunder bird's problem. But, if I run with the INDEX on a local disk, many mailboxes will not load (the most critical ones, of course...), but also some do. My inbox will list messages, but cannot display any. Others won't even list messages. I'm at a total loss how to proceed, here. I've tried everything I can think of to debug what's going on, but have gotten nowhere (well, I did discover the whole lock_method=fcntl trick). I've tried enabling rawlog, but am just not familiar enough with IMAP to get help from those logs. Here's what's happening in a typical mailbox: % pwd /home/mario/.mail/Maildir/.SI2 % ls -al total 544 drwx--S--- 5 rvvk40 lowv 425984 Dec 2 14:42 ./ drwx--S--- 64 rvvk40 lowv 16384 Dec 2 14:43 ../ -rw------- 1 rvvk40 lowv 15 Nov 16 07:16 .customflags -rw------- 1 rvvk40 lowv 24 Dec 2 14:38 .nfs00986 -rw------- 1 rvvk40 lowv 24 Dec 2 14:40 .nfs08986 -rw------- 1 rvvk40 lowv 312 Dec 2 14:11 .nfs16686 -rw------- 1 rvvk40 lowv 24 Dec 2 14:32 .nfs1A886 -- 40+ deleted here for brevity -- -rw------- 1 rvvk40 lowv 24 Dec 2 14:39 .nfsE3986 -rw------- 1 rvvk40 lowv 312 Dec 2 14:38 .nfsEF886 -rw------- 1 rvvk40 lowv 24 Dec 2 14:26 .nfsF3886 -rw------- 1 rvvk40 lowv 312 Dec 2 14:32 .nfsF9886 -rw------- 1 rvvk40 lowv 312 Dec 2 14:17 .nfsFF686 drwx--S--- 2 rvvk40 lowv 4096 Dec 2 07:58 cur/ drwx--S--- 2 rvvk40 lowv 4096 Dec 2 07:58 new/ drwx--S--- 2 rvvk40 lowv 4096 Dec 2 07:58 tmp/ % pwd /home/mario/.mail/Maildir/.SI2 Help!

[Dovecot] Silly newbie questions...
by Michael Segel 03 Dec '05

03 Dec '05

Hi, I'm relatively new to dovecot, less than 48 hours, and I've ran in to a few bugs in the installation/configuration process. Here's my set up. I have my own domain. Within the domain, I have a couple of Linux boxes. So I control both my primary and secondary mail servers. My Linux boxes are a mixture of SuSE 9.2, 9.3 and 10.0 (All based on age of the hardware.) I'd like to use Postfix for my MTA, which I have up and running, but I'd also like to add an IMAP server (hence dovecot) so I can get my mail from any of my PCs and my blackberry.) On my main mail server, I have KDE running and it uses ~/Mail/inbox/(cur,new,...) When I tried to use KDE on my other Linux server, I got it to authenticate and I could see the folders, but I couldn't see any of the mail. (Its all in cur subdirectory.) Now I did notice that when Postfix gets a mail message, its placed in /var/spool/mail/msegel which would imply its using an mbox format. So what am I missing? TIA! -Mike -- Michael Segel Principal MSCC

[Dovecot] corrupt attachments
by Brian Thompson 02 Dec '05

02 Dec '05

Not sure if this has already been covered, but any pointers or suggestions would be greatly appreciated. We just realized last night that dovecot-stable seems to be corrupting the attachments within users' inboxes. In an attempt to resolve the problem, we upgraded the mail server here to Dovecot 1.0alpha4 but it didn't help. To the best of our knowledge we didn't start experiencing this phenomena until we migrated from Solaris 8/Sparc to Solaris 10/x86 about 3 weeks ago. To be more specific: A non-corrupt attachment can be sitting within a user's mail spool (mbox format) and live there without a problem until an imap client goes to download the attachment via dovecot. At that time, dovecot seems to be stripping the last four characters from each base64 encoded ascii line within the attachment and rewriting the message within the mail spool without those characters. From then on, the attachment is permanently corrupt, even via local unix direct file access clients such as pine or elm. We've temporarily switched back to UW imapd, but users have noticed the decrease in speed - not having the indexing available. Again, any suggestions would be greatly appreciated. Thanks, Brian

[Dovecot] Multiple authentication databases and storage locations
by Odhiambo Washington 02 Dec '05

02 Dec '05

Hello Everyone, I am playing with the $subject matter using 1.0alpha4, and thanks to the archives, I lifted this one from Alexander Shikoff off and used it in my setup. auth default { mechanisms = plain user = root passdb pam { args = pop3 } passdb sql { args = /usr/local/dovecot/etc/dovecot-mysql.conf } userdb passwd { } userdb sql { args = /usr/local/dovecot/etc/dovecot-mysql.conf } } It seems to work, but I have virtual users as well as system users. System accounts have their mail stored as follows: default_mail_env = maildir:/home/%u/Maildir While virtual users have this: default_mail_env = maildir:/htdocs/virtual/spool/%d/%u/Maildir Now, virtual users can login because I have used their $default_mail_env in my configuration. I am stuck how to get system users to successfully access their e-mails. Here is the error I get: beastie# telnet 0 110 Trying 0.0.0.0... Connected to 0. Escape character is '^]'. +OK Welcome. Dovecot is Ready to serve. user wash +OK pass a_verysecret1 +OK Logged in. -ERR No INBOX for user. Connection closed by foreign host.

[Dovecot] After restart dovecot do not serves IMAPS anymore
by Marian Hercek 02 Dec '05

02 Dec '05

I had to restart computer yesterday and now Dovecot has strange behaviour. Dovecot is running and should serve IMAPS, but client Mozilla Thunderbird cannot connect. I tried openssl s_client -connect localhost:993 and it said only CONNECTED(00000003). A time ago when everything was OK, the listing after connection was "a bit" longer than it is now. I remember there was "OK, dovecot ready" or something like that. Now, there is none. Of course in /etc/dovecot.conf: protocols = imaps imaps_listen = * ssl_disable = no So, what's the problem?

[Dovecot] Dovecot logs to syslog (other than MAIL)?
by Steve Bigley 02 Dec '05

02 Dec '05

I see in the config file where I can enable syslog, but then all logging goes to the MAIL facility. I could find no reference to changing the facility:level for syslogging. Is that implemented, or planned? I know I could just write it to a file, but I'd prefer to use syslog because then I can pipe it to a central logging server.

I am using qmail-ldap to provide virtual users to my system, but I also have some shell users on the system as well. Virtual users go into /home/vmail/mailstore/$username/ System users go into /home/$username/Maildir How can I have both of these available as inboxes in dovecot using ldap logins?

[Dovecot] Unused SQL API
by Curtis Maloney 02 Dec '05

02 Dec '05

Greetings, recently I've been writing a database driver module for Dovecot to use SQLite. It's mostly for my own use, but I do recall other people have asked for this. Firstly - Timo, I grow to love your work more and more every day. :) I have not had any trouble figuring out what is needed of the driver, even without any API documentation. However, the one part of the driver that's given me pause has turned out to most likely be unnecessary. Whilst I was trying to work out how to deal with the sql_result->get_values() call without leaking memory, it seemed an odd method to have along side the other calls. So I decided to look for where it was used, to try to understand. Only, it isn't. The _only_ point I can find in the sources that calls that method is in the Postgress SQL driver. Am I missing something? -- Curtis Maloney cmaloney(a)cardgate.net

[Dovecot] Question on moving folders
by Andy Cravens 02 Dec '05

02 Dec '05

Is there a way to move an imap subfolder up one level? I have a bad mouse and every now and then I have accidentally dragged an imap folder on top of another folder. I am unable to get the original folder back up one level. I've tried using several clients and I can't get it to work with dovecot. I keep getting a "folder already exists" message. I'm guessing dovecot still sees the original folder before it was moved. Any tips... besides getting a new mouse? -- Andy

[Dovecot] Chrooting question
by Greg Pendler 01 Dec '05

01 Dec '05

Hi, All. I've got a feeling it's a simple matter and it was discussed on this list (i've searched the archive) but still all answers i've found didn't solve this problem. We want to move from UW-IMAP to dovecot, when users INBOX is /var/mail/USER_NAME and his folders are ~USER_NAME/mail/. In addition the host is an FTP server that uses chrooting in order to prevent users from accessing files outside their home directories. Our /etc/passwd line looks like this: some_user:x:1234:123:Some User:/home/./some_user:/bin/shell When i try to check mail on this host with this user i receive the following error message: Dec 1 08:21:11 server dovecot: [ID 935345 mail.error] Invalid chroot directory '/home' (user some_user) (see valid_chroot_dirs in config file) After which comes a line with: "Internal login failure" I've tried to configure different chroot options in configuration file, but had no luck at all. Of course when i remove the "." from passwd line everything works great (except FTP:). I'm using 1.0 alpha 4 on Solaris 9. Please let me know if you have such setup and what is the exact setting i need to add to configuration. Thanks in Advance, Greg

[Dovecot] dovecot 1.0.alpha4 hangs at auth
by Mihai Secasiu 01 Dec '05

01 Dec '05

I'm using dovecot 1.0.alpha4 on a freebsd 5.3 i386 system. Dovecot is configured to use mysql authentication and I'm running mysql 5.0.15 . Everything works fine, but after a period of inactivity (20-30 minutes ) when I connect and try to authenticate it just hangs. I noticed that the dovecot-auth worker process is not running anymore... from looking at the source code I understand that the dovecot-auth worker process is actually a client that connects to the main dovecot-auth process ( the server) I restarted dovecot and I straced the auth worker process ... after 20-30 minutes it just existed here is the output of strace : gettimeofday({0, 0}, NULL) = 0 poll([{fd=5, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=4, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 2, 0) = 0 gettimeofday({1133138508, 221796}, {0, 0}) = 0 gettimeofday({0, 0}, NULL) = 0 poll([{fd=5, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=4, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL, revents=POLLIN}], 2, 1999) = 1 gettimeofday({1133138509, 49095}, {0, 0}) = 0 read(4, "", 478) = 0 close(4) = 0 fcntl(7, F_SETFL, O_RDWR|O_NONBLOCK) = 0 read(7, "", 8192) = 0 fcntl(7, F_SETFL, O_RDWR) = 0 write(7, "\1\0\0\0\1", 5) = -1 EPIPE (Broken pipe) shutdown(7, 2 /* send and receive */) = 0 close(7) = 0 close(3) = 0 close(5) = 0 close(6) = 0 close(-1) = -1 EBADF (Bad file descriptor) exit(0) = ? Why is the auth worker exiting if it reads 0 from fd=4 ? is it possible to make it so that it does not exit ? and in the case it exits is there a mechanism to restart it? Another question would be why read(4, "", 478) returns 0 ? this means that the server closed connection right ? why would the auth server close the connection with the auth worker ? I had a similar problem with dovecot 0.99 but there I got a "login failed" error message immediately , with 1.0alpha4 it just hangs. I also used a nightly cvs snapshot and the problem is there too. Thank you for your time Mihai Secasiu http://denixsolutions.com/

I do a : telnet localhost imap Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK dovecot ready. 1 login user pass (here is the delay) After passing a username/password, the process is like stuck for some reason. I have to killall dovecot processes and do a: service dovecot restart and it work again. I have 1.5GB left on the disk and this problem just appeared now after month of working correctly. Could it be the disk space? How can I debug the problem? Should I migrate de 1.0alpha4? Does alpha4 have a new code in the authentication phase?

[Dovecot] Not an IMAP4 Server?
by John Gray 28 Nov '05

28 Nov '05

I've been testing alpha4, and every once in a while my client (Thunderbird 1.5 RC1) tells me the dovecot isn't a valid IMAP4 server. This is usually (maybe always) when I first bring up the client up. If I just ask the client to get the mail again, it does so happily (without any errors). I must say I found dovecot as a pleasant surprise. We have been using UW. Which didn't scale well. I was considering going to cyrus, but dovecot seems to have given much (if not all) of performance improvements without all the hassle of conventing all the existing mbox mail to maildir.

[Dovecot] authentication failure messages in log
by Daniel 26 Nov '05

26 Nov '05

Hi I'm using Dovecot 1.0.stable branch on a production Fedora Core 3 server. All is running very well other than I getting tons of these messages in the log (/var/log/messages): Nov 26 13:38:56 bmw unix_chkpwd[19360]: password check failed for user (xxxx) Nov 26 13:38:56 bmw imap(pam_unix)[19359]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost=x.x.x.x user=xxxx However the sessions are authenticating correctly and the user is able to down load the mail fine. I have tested this. I send mail to an account then login and download the mail correctly, however my session gets the above in the messages log. Each log on to dovecot get ones of these messages in the log. It making the log file large. Any idea on what it is? Regards Daniel -- "Unix is simple.

[Dovecot] Problem with mysql authentication
by Jacek Osiecki 25 Nov '05

25 Nov '05

Hi, I'm trying to set up dovecot-stable (http://www.dovecot.org/nightly/stable/dovecot-stable-20051124.tar.gz) All seems to be prepared correctly, but... my dovecot can not access the mysql database :( Connection string goes like this (i tried changing the order of parameters, that's why password is the first in the line): connect = password=***** host=/var/lib/mysql/system/mysql.sock dbname=vmail user=vmail But - in dovecot log I see: dovecot: Nov 24 23:53:05 Error: auth(default): mysql: Connect failed to vmail: Access denied for user 'vmail'@'localhost' (using password: TAK) Same in mysql log: 051124 23:53:05 171 Connect Access denied for user 'vmail'@'localhost' (using password: TAK) All settings in connection string are 100% correct - I have pasted them from dovecot-sql.conf to command-line mysql client and it worked, I have logged in. My copy of dovecot has been compiled recently, so all libraries are correct. Mysql version is 5.0.15 - but I doubt it is the reason... Can anyone help? Thanks in advance!

[Dovecot] Newbie question: shared folders means..?
by Jeff Turner 22 Nov '05

22 Nov '05

Hi, The website says "Shared mailboxes aren't yet supported". Does that mean that one shouldn't have two mail clients (same username) accessing the same IMAP account simultaneously? Or that Dovecot doesn't support distinct users accessing the same 'shared' Maildir box? Cheers, Jeff

[Dovecot] Silly question...
by Michael Segel 22 Nov '05

22 Nov '05

I'm trying to build a new 1.0+ copy of dovecot. I'm trying to build it so I can use SSL. I tried the ./configure --with_ssl= option, did a make clean, then a make and a make install. Still get the same error saying that even though I set the SSL use flag, it was not compiled with SSL. Thoughts? TIA! -- Michael Segel Principal MSCC 312 952- 8175 [M]

[Dovecot] What's the best way to do this?
by Michael Segel 22 Nov '05

22 Nov '05

Hi, Got a situation where I have a couple of mailing list subscriptions as well as system generated e-mails from my clients' computers sending me warning messages. (Along with my normal load of personal e-mail). Does it make sense to set up virtual mailboxes (maildirs) one for each mailing list or group? Then using an IMAP client to subscribed only to the lists that I *want* to read? My biggest problem is that I have a blackberry and I don't want to get interrupted for non-critical e-mail. Or is there a better solution? TIA! -Mikey -- Michael Segel Principal MSCC 312 952- 8175 [M]

[Dovecot] How to add the footer to multipart emails
by Magnus Holmgren 21 Nov '05

21 Nov '05

I recently lerned that Mailman adds its footer to MIME multipart messages by putting the original message in the first part of a new multipart/mixed entity and the footer in the second part, with Content-Disposition: inline. It works well in Thunderbird at least, i.e. the footer is visible; the glitch is that the footer shows up as an attachment as well, as does my PGP/MIME signature. Would this be something for EoC to adopt? It would allow non-ASCII characters as well (but not in text/plain messages). -- Magnus Holmgren Linköping, Sweden

Re: [Dovecot] messages_count too large (2578 > 2566) Help!
by Rob Frohne 21 Nov '05

21 Nov '05

Hi Everyone, I found that I could "fix" the problem by moving all my messages from Maildir/cur/ to a temporary location and then try and load the inbox using Thunderbird which then saw no messages, and then moving them all back into Maildir/cur/ and then Thunderbird loaded them fine. I have had this funny business with messages_count to large happen twice tonight now. Both times after I deleted dovecot* in the Maildir/ folder. Hope this helps someone else if they end up with the same issue, or perhaps it might help Timo figure out what is happening. Thanks, Rob -- Rob Frohne, Ph.D., P.E. E.F.

[Dovecot] Big THANKYOU to Dovecot development team
by Will Blake 21 Nov '05

21 Nov '05

Time for a positive message. As a (very) part time administrator of a small network running on an ecclectic bunch of machines I'd like to thank the dovecot team for developing such an easy to use and faultlessly functional product. Having been forced into finally replacing my UW IMAP server, I'm glad to have hit on Dovecot after struggling with mailbox transfer issues with cyrus and almost tearing my hair out. On my Fedora4 server, Dovecot was running withing a minute and reading all my folders in five further minutes, thanks Guys, Will.

[Dovecot] Shared Mailboxes, Per User SEEN flag and Mailing lists
by Reikan - Sidney Ferreira 20 Nov '05

20 Nov '05

Hi! Im making a small research about IMAP servers and it's features. As the subject suggests, I want make a shared mailbox, with per user \seen flag to work like a mailin-list works. The reason to use 1 shared folder is simple: Imagine 12k users sending 1KB messages each week, it will be 12+ MB of useless information. Many people told me that IMAP could do this, but now seem that it is a little harder then what they made it look like. Finally, some EXIM users told me that Dovecot could handle it a little better than Courier, so, Im here to try to find more information about it. Follows the mail that I received from an EXIM user.

[Dovecot] Sorting messages by date
by Stephen Allen 19 Nov '05

19 Nov '05

I've recovered a load of messages from a different mail server without it's index file (it was corrupted). I now have thousands of messages which display in Outlook Express (yes, you may puke at this), all as today's date. However when I read them in Pine, the date of each message is displayed correctly, but they're in no particular order whatsoever. There are several questions here, some of which aren't suitable for this list, but for completeness... 1. Does Dovecot store what it thinks is the date the message arrived, in it's index file? 2. Can I fake Dovecot into thinking the messages arrived on a different date by including something in the message headers, or changing the date/time stamp of each file (but I don't know how to do this)? 3. Pine correctly picks out a date from the message (although it doesn't sort by this order), and Outlook Express just displays everything as the date which it (or Dovecot) first saw the message. Does Outlook rely on Dovecot's sorting/date information or does it do it's own? Many thanks, Steve :)

[Dovecot] Can Dovecot work with an RDBMS for mail/attachment storage?

This may seem off the wall, but can dovecot be configured to support a connection to a database server and use the database server to store the e-mail message and its attachments? While you can use Postgres and MySQL for storing and authenticating users, there is a possibility to use an RDBMs to control the mail itself. Thoughts? -- Michael Segel Principal MSCC

[Dovecot] Retention Policy Feature(?)
by Ted Strzalkowski 18 Nov '05

18 Nov '05

I am currently using dovecot 0.99.14p1 on OpenBSD 3.8, mbox format, procmail+sendmail MTA. I subscribe to quite a few mailing lists and currently have procmail sorting mail into the proper mboxes. I was hoping there would be some sort of retention policy feature built in to dovecot. I want to delete mail more than X days old from X folders. I have combed the documentation, list archives, and google. Is this a feature? If so, where can I find more information on it. If this isn't a feature, is it in the works or is it left out to keep things "slim line"? Ted Strzalkowski

[Dovecot] Authentication hanging with 1.0alpha4 - mysql issue?
by brock＠theskeptik.com 18 Nov '05

18 Nov '05

Hello, Recently, I configured my server (RHEL4, 2.6.9-22.0.1.ELsmp) to run postfix 2.1.5 and dovecot 1.0 alpha4. It connects to a MySQL database (mysql 4.1.12) to verify authentication. From 30 minutes to an hour after dovecot is started, authentication and mail access works perfectly. However, after those 30 minutes to an hour, further attempts to authenticate with dovecot result in "hangs" - no temporary authentication errors are reported to the client, and no errors are logged to the dovecot log. The dovecot is still running, and responds to connections, but once the password is sent, the server fails to respond. The following line is registered in the log with each authentication attempt after the "hang": > dovecot: Nov 17 22:44:41 Info: auth-worker(default): mysql: Connected to localhost (postfix) along with an eventual disconnection notice (although no Login: line is registered): > dovecot: Nov 17 22:45:41 Info: imap-login: Disconnected: Inactivity: method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Killing and restarting dovecot immediately fixes the problem, although it reappears after 30 minutes to an hour. Following is my dovecot-sql.conf: driver = mysql connect = host=localhost dbname=postfix user=dovecot_read password=**obfuscated** default_pass_scheme = PLAIN-MD5 password_query = SELECT password FROM mailbox WHERE username = '%u' user_query = SELECT 89 AS uid, 89 AS gid FROM mailbox WHERE username = '%u' (dovecot_read has SELECT access on the postfix database, and 89 is the uid/gid of the owner of the maildirs.) I searched through this list's archives over the last two months and couldn't find anything related to this. Does anyone have any idea what the problem could be? Regards and many thanks in advance.

[Dovecot] Dovecot dead after upgrade of MySQL

[Dovecot] Mailbox isn't a valid mbox file
by Cliff Hayes 16 Nov '05

16 Nov '05

Hello all, I have a new installation of Fedora 4 and Dovecot 1.4.Alpha4 A small percentage of my users are getting unable to pop mail from a client (ie: Outlook), they get continually prompted for username/password. The error they get is: Mailbox isn't a valid mbox file. When I look in the file, I don't see anything unusual. There's not much info on the Internet about this problem. The only thing I found mentioned blank lines in the file. So, I tested and found that I'm able to get mail on other accounts regardless of whether there are blank lines in between messages. Thanks, Cliff

[Dovecot] Improper listening on IMAPS
by Marian Hercek 16 Nov '05

16 Nov '05

I want Dovecot handling IMAPS. /etc/dovecot.conf: protocols = imaps imaps_listen = * ssl_disable = no ssl_cert_file = /etc/ssl/certs/dovecot.pem ssl_key_file = /etc/ssl/private/dovecot.pem The problem is that Dovecot is not listening on 993 port, or there's something listening on 993, but it does not introduce itself. There's no problem if Dovecot listens on 143 (IMAP). When I telnet on 143, Dovecot introduces itself like this: $ telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK dovecot ready. But when I telnet on 993: $ telnet localhost 993 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. There is not other process that would be listening on IMAPS 993 port. Dovecot was compiled with SSL support: # ldd /usr/sbin/dovecot libssl.so.0.9.7 => /usr/lib/libssl.so.0.9.7 (0x20597000) libcrypto.so.0.9.7 => /usr/lib/libcrypto.so.0.9.7 (0x205c6000) libdl.so.2 => /lib/libdl.so.2 (0x206ba000) libc.so.6 => /lib/libc.so.6 (0x206be000) /lib/ld-linux.so.2 (0x20580000)

[Dovecot] Sub-Folder Query
by Kaan Kivilcim 16 Nov '05

16 Nov '05

Hi all, I have a question in regards to folders/sub-folders with dovecot and Microsoft Outlook 2000. When creating folders if you do not append a "/" to the end of the folder name you cannot create sub-folders. Is there any solution/work around so that users do not have to append a slash on the end of the folder name? I would like to use dovecot for about a 50-user IMAP server however adding a slash to the end of folder names won't go down well with the users who are not the most computer literate people.

[Dovecot] Need to move mail
by Brent Clark 15 Nov '05

15 Nov '05

Hi all My imap server is getting to the stange where I need to start worring about the disk usage. Due to the number of users we seem to be hiring, I need to start looking at a new mail server, suppose its a blessing in disguise too. Would it be ok to just tar my current users mail (there home directory, I dont use virtual setup) and the untar it on the new mail server. Is there anything that dovecot on the new machine will complain about. Obviously I would tar everything, indexes etc. Just something I was wondering. Kind Regards Brent Clark

[Dovecot] a proposal to increase the stability
by Udo Rader 15 Nov '05

15 Nov '05

Hi, we've been using dovecot for the past 2 years or so for our 3K+ mail accounts and have never regretted our step. Yet from time to time there appear to be, how shall I say, "major" problems in the daemon that of course are no reason to whine and complain about because dovecot is OSS and everybody can do something about it. And that's where I would like to make a suggestion. From our own software projects I am used to the usage of extensive testing frameworks, like junit for java based applications. I almost completely lack knowledge about C/C++ programming, so I have no idea if something like this could be done for dovecot. For "the other end" of the mail chain I know dumbster, which is a fake SMTP server used for testing MUAs. So maybe something similar could be done for IMAP/POP3 servers? What I am thinking of is to run those tests before anything new is released. On the other hand I cannot even estimate how much work would be needed for this ...

[Dovecot] Leftover mbox behavior from uw transition
by Adam Porter 15 Nov '05

15 Nov '05

Currently running dovecot 0.99.12 on a RHEL 3 server. This system used to use UW imap with mbox mailboxes, is now using dovecot with Maildir. (Actual user shell logins are not permitted.) Performance is tremendously improved. However, we still have users that have their client imap root set to the "mail" or "mail/" directory. (Can't reach/change them all easily.) As a result, people are still (inadvertently) creating/using mbox-style mailboxes (sent mail folders most often) on the dovecot server (dovecot of course handles them without complaining) which grow and hurt server performance. Now that we've figured this out, I think we could use mb2md in a script to convert these big mbox files to Maildir. (Is there a better way?) But what would be the smart way to prevent people from creating these mbox files and still have their client work correctly with their imap root set to "mail"? We currently use: default_mail_env = maildir:~/Maildir Thanks! -Adam

[Dovecot] entourage pop to dovecot imap migration
by wagner 15 Nov '05

15 Nov '05

I'm beginning to migrate my years of mail stuck in Entourage 2004 (MacOSX) to dovecot imap on Fedora FC4. No matter how I have tried I cannot get the status flags to migrate. Eg: all the mail, once transfered from the pop archive to the imap server looses all Status: and X-Status: flags and ends up being marked "new" on the imap side. After lots of testing it appears that, while simply having both pop and imap configured Entourage and dragging messages from the pop config to the imap area does move messages, all flags are lost. This also is the case if I export Entourage folders as mbox files and then import them into the imap server with Entourage or Mail.app. Has anyone else came upon this obstacle? Any advice? I am in the process now of gathering information to facilitate my own "migration utility". It seems the Entourage DB keeps the read/flagged/replied flags for each message in its own internals and doesn't deem it worthwhile to export them as part of it's mbox export nor retain them as Status or X-Status flags when moving messages from its pop DB to the imap server. I believe I can write a script to work on a set of found, for example, "replied to" messages to add an "X-Status: A" to their headers before moving them to the imap server. Same for "read" and "flagged" MS DB internals to Status/X-Status headers. With these headers added, moving them to the imap server, from my limited testing would seem to be the method to keep those status flags per message? Does dovecot use those flags or does it have its own means of storing that status information? Will it at least use those in the messages to populate its DB if it does have its own method? Flags I've identified so far: Status: O - old Status: RO - recent old(?) X-Status: A - replied to X-Status: F - flagged Thanks for any insight or suggestions.

[Dovecot] problem with content-length and mbox parsing
by Glenn Leavell 15 Nov '05

15 Nov '05

The stars aligned recently such that I sent someone a message that contained a line similar to this in the message body: From glenn(a)usg.edu Thu Jun 20 16:48:11 2002 (Except that there wasn't that space character *before* the From; I've added it here to avoid any problems with this message). Dovecot wrote a copy of the message in my "sent mail" folder under the direction of my imap client. But when I went back to *read* that folder (still through Dovecot), it was broken and was presented as two corrupted mail messages. About a year ago, there was a thread on the list about the fact that Dovecot does not perform >From quoting when writing to mbox folders: http://dovecot.org/list/dovecot/2004-October/004865.html Timo, in that thread you mentioned the following about Dovecot's use of the content-length header: On Tue, Oct 05, 2004 at 05:13:36PM +0300, Timo Sirainen wrote: > Dovecot (and eg. mutt) uses Content-Length header to figure out how > large the message body is, so clients can't mess anything by sending > From-lines. Also Dovecot requires that From-line has correct syntax and > valid timestamp or it's not treated as From-line. In the example above, the message *does* include a valid content-length header after it is initially written, but Dovecot seems to ignore the header when reading the folder, and it treats the "From " line in the body as a message separator. For example, a SELECT on the folder will return "2 EXISTS" even if the single message described above is the only message in the folder. I'm currently at CVS 20051104. Glenn

[Dovecot] IMAP limitation
by Tom Allison 15 Nov '05

15 Nov '05

I was trying to delete a LOT of email messages in one shot from Thunderbird. I selected everything in a folder (>10,000) and then hit DELETE. I received an IMAP error. It clearly implied a limitation to just how many UIDS I can submit on an IMAP request at a time. Is this a limitation of dovecot? (I'm assuming it is). I can work around this, I think, because I haven't found a limitation to retrieving a list of email message UIDS as yet. I could thereby send splices or chunks of that list of UIDS to delete. I ran into this while trying to do a variety of obscene things in my attempts to develop a web mail application. Because of the number of strange tests I have, I don't really "blame" anything since I'm not sure that anyone really expects to delete 10,000 messages at one command.

[Dovecot] TLS negotiation from client fails after openssl upgrade

Is anyone using dovecot on Fedora fc5-devel? I had to rebuild my rpm of alpha4 due to dependencies when I pulled in openssl-0.9.8a (with a whole bunch of other updates). Now when I start my mail client (balsa) it tells me it "Cannot connect to the server: TLS negotiation failed". Dovecot wrote in maillog: "imap-login: Disconnected: rip=1.2.3.4, lip=1.2.3.4, TLS". Does anyone else see that? Can anyone advise me how to debug this? Thanks, Willem Riede.

[Dovecot] Dovecot, Outlook Express and new accounts
by news.gmane.org 12 Nov '05

12 Nov '05

I have come across a strange situation, involving new accounts. I am running Dovecot 0.99.10-5 on Fedora Core 2. Dovecot is configured to use pam for authentication, and the dovecot pam service is configured to use pam_mkhomedir. When an account is created and the user logs in through SquirrelMail, there is no problem. The standard folders are available - Inbox, Drafts, Sent Items and Trash. When logging in through Outlook Express first, it gives the following error:- The server did not respond to this IMAP command before the connection was terminated. Configuration: Account: mail.server Server: mail.server User name: username Protocol: IMAP Port: 143 Secure(SSL): 0 Code: 800ccc0f A packet trace shows the following:- <<< * OK dovecot ready. >>> 008E CAPABILITY <<< * CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN LISTEXT LIST-SUBSCRIBED STARTTLS AUTH=PLAIN <<< 008E OK Capability completed. >>> 008F LOGIN "username" "password" <<< 008F OK Logged in. >>> 008G IDLE <<< + idling >>> DONE <<< 008G OK Idle completed. 008H LIST "" "*" Connection to host lost. My suspicion that Outlook Express is not intelligent enough to create the folders, although the sudden connection drop might indicate a bug. If it is not a bug, is there a workaround?

[Dovecot] Asserion Failure in Current CVS

Just installed the version from CVS as of Oct. 27. I noticed three problems quite quickly: Still seeing "(imap) killed with signal 14" My INBOX closed with "access error" after reading it for a bit. There's nothing in the logs or anything, but this hasn't happened for quite a while now. There where quite a lot of incoming messages at the time and I was marking messages as deleted using pine. After reverting to the last version of dovecot that I was using and restarting pine, it opened quickly (no reindexing) and the deleted emails where marked as deleted.

[Dovecot] Folders mysterously deleted
by Andy Cravens 12 Nov '05

12 Nov '05

Using alpha 3 on Solaris 9. One of our users reported all folders except his inbox were missing. I went to the server and looked at the logs and could find no indication that a sysadmin had logged in and deleted the folders. Also found no indication of anything unusual in the dovecot log file. Has anybody seen a situation where dovecot deleted folders?

[Dovecot] dovecot 1.0alpha 4 error
by Alex Campoe 11 Nov '05

11 Nov '05

I tried to research this but could not find anything. Apologies if someone already reported this issue. I was running alpha 3 on Solaris 9, and having some timeout issues on lasge mailboxes. Decided to upgrade to rc4 before tweaking anything else. On rc4, when I try to start dovecot, I am getting: dovecot: Nov 10 14:04:56 Info: Dovecot v1.0.alpha4 starting up dovecot: Nov 10 14:04:57 Error: child 18805 (auth) returned error 89 dovecot: Nov 10 14:04:57 Error: Auth process died too early - shutting down dovecot: Nov 10 14:04:57 Error: auth(default): Unknown userdb driver 'passdb' No changes on .conf file.

[Dovecot] dovecot-example.conf error with POP3 UIDL format?
by Shayne Hardesty 11 Nov '05

11 Nov '05

I just installed dovecot 1.0alpha4 on a very busy RHEL4 server with about 1300 users. So far so good, except for the dreaded duplicate emails in outlook for users who use POP3 and have "leave message on server" selected. After searching the archives I found that this is usually related to the UIDL format. The example in the .conf file is this: / # If you want UIDL compatibility with other POP3 servers, use: # UW's ipop3d : %08Xv%08Xu / Note that 'v' comes first, then 'u'.. But, right under it, is this: / # Note that Outlook 2003 seems to have problems with %v.%u format which was # Dovecot's default, so if you're building a new server it would be a good # idea to change this. %08Xu%08Xv should be pretty fail-safe. / In this example (and the next example just under it) 'u' comes first, then 'v'. So is the first example right, in that %08Xv%08Xu is compatible with UW ipop3d, but not outlook? Or is the UW ipop3d example a mistake? For what it's worth %08Xu%08Xv seems to have fixed my users' duplication problems. Shayne

[Dovecot] Moving from mbox to maildir?
by Patrick 09 Nov '05

09 Nov '05

Hi all, New to the list. I have an updated FC4 box with Dovecot version 0.99.14.4.fc4. My mbox size is about 76 megs and growing rapidly because of several high-volume mailing lists I'm subscribed to. I have noticed that over time the performance of the Evoluion/Spamassassin/Dovecot combo deteriorates. Someone on the Fedora users list suggested I have a look at moving to a maildir setup. Reading the docs I can't really figure out what to. Does anyone have a suggestion how I can safely move my mbox setup to a maildir setup? Much appreciated! Regards, Patrick

[Dovecot] mysql dovecot 1.0alpha4

I try to authenticate using mysql and I always get access denied. I wrote a program in C that connect to the database and it work. I put the code within driver-mysql.c and it failed!!! My question is do you set up anything (SSL?) that could explain this failure. thanks. Here is the code MYSQL *h; h = mysql_init (NULL); if (h == NULL) { fprintf (stderr, "mysql_init() failed (probably out of memory)\n"); exit(1); } if (mysql_real_connect ( h, /* pointer to connection handler */ "localhost", /* host to connect to */ "lyra", /* user name */ "xxxxxxx", /* password */ "lyra", /* database to use */ 0, /* port (use default) */ NULL, /* socket (use default) */ 0) /* flags (none) */ == NULL) { fprintf (stderr, "mysql_real_connect() failed:\nError %u (%s)\n", mysql_errno (h), mysql_error (h)); exit (1); }

[Dovecot] Problem with different case logins
by Roberto Suarez Soto 09 Nov '05

09 Nov '05

Hi, we have a system (Debian sarge) that uses LDAP for user authentication, via pam. We also have virtual users by using a static userdb [1], using the directory structure /var/lib/dovecot/postoffice/%u (i.e., a directory under /var/lib/dovecot/postoffice with the name of the user). The directory /var/lib/dovecot/postoffice belongs to postoffice:mail. IMAP folders, indexes and stuff go here; normal mail goes into /var/mail/%u. We are using dovecot 1.0alpha3 (upgrading to alpha4 soon). Today we've found a grave problem. Let's suppose you have the login "mylogin.domain.com". If you instead use the login "MYLOGIN.domain.com", the authentication works anyway (which is Ok), but dovecot creates a new directory under /var/lib/dovecot/postoffice with the different case, i.e., /var/lib/dovecot/postoffice/MYLOGIN.domain.com (which is not Ok). Afterwards, you can only access this new folder if you use the login with the caps. A new file (we're using mbox) under /var/mail/ with the new name is also created, though I don't understand yet how. We're using Postfix as MTA, and it always delivers to the lower case name. I hope you can understand the problem. If an user logs with a name with just one letter changed from lower case to upper case, all his/her folders and mail will be seemingly gone. Is this a bug or a feature? If the latter, is it possible to change this behaviour, or at least work around it? Thanks in advance. -- Roberto Suarez Soto Allenta Consulting robe(a)allenta.com www.allenta.com

[Dovecot] dovecot and passwd-file migration
by Erick Perez 09 Nov '05

09 Nov '05

Hi, Im using dovecot with passwd-file authentication and would like to provide some kind of interface/script to let the users change their password. currently my passwd-file looks like: user@domain.com:{PLAIN}password I would also like to change the password to the same I use in my Linux user(a)domain.com: {MD5}password ??? What do I need to change in the .conf? Las thing, I just cant find a RPM or Source RPM for dovecot compiled with MySQL support. Our office uses MySQL and not Postgres. doing rpmbuild --rebuild --with mysql to the .src.rpm of dovecot does not work. dovecot fails telling he has no idea of what mysql is. If I get a dovecot with mysql rpm I will move from passwd-file to Mysql auth.

[Dovecot] major pop3+ldap problem with alpha3 and alpha4
by Udo Rader 07 Nov '05

07 Nov '05

hi, For some of our customers we provide a pop3 access, and after an upgrade to alpha3, it is not working anymore. All of our data is ldap based and everything is working as before for our IMAP customers, but our POP3 users fail. Obviously the pop3 login process does not read the data correctly that comes from ldap. after enabling mail_debug, I saw the following error in our log: --------CUT-------- dovecot: Nov 02 18:01:32 Info: pop3(some.one.at.work): mbox: data=/virtual/at.work/home/some.one/mail/:INBOX=/var/mail/some.one.at.work --------CUT-------- The INBOX should be /virtual/at.work/var/mail/some.one.at.work, yet the POP3 process obviously uses the default_mail_env settings. the relevant line in our dovecot-ldap configuration looks like this: -------CUT-------- user_attrs = uid,homeDirectory,MailMessageStore,,uidNumber,gidNumber -------CUT-------- As I said, the IMAP process uses the ldap data correctly. any ideas?

[Dovecot] deleteing e-Mail, quota and dovecot
by Götz Reinicke 07 Nov '05

07 Nov '05

Hi, we run a RHEL4 E-Mail-Server with dovecot-0.99.11-2.EL4.1. we use mbox and most users use imap. So I have set quota for the devices where the user mailfiles are saved. No I'm getting the situation, that users exide there quota but yet not the grace limit and the user isn't able to delete messages. e.g. the the soft limit is 100 MB, the hard limit is 110 MB. So there should be some space to delete unneeded emails. Am i thinking the wrong way? Or how should the quota-system work in this situation? Thanks for any ideas!

[Dovecot] Setup help
by Patrick Ernst 06 Nov '05

06 Nov '05

I'd previously had dovecot running on a Debian server but recently migrated to Suse. The nice, simple setup for dovecot on debian is not as easy using the dovecot sources. My lack of experience I'm afraid! I'd like to continue to use dovecot, especially as my current maildir directories are all set up ready to be use again. On suse (sles9) I have users authenticating by LDAP. In /var/log/dovecot I am getting errors like dovecot: Oct 27 22:17:41 Warning: Killed with signal 2 dovecot: Oct 27 22:28:03 Error: auth(default): LDAP: ldap_simple_bind_s() failed (dn uid=dovecot,ou=people,dc=aro,dc=home): Protocol error The errors also include the same LDAP error but with signal 11 or 15 I cannot get dovecot working. I've tried the 1.0 alpah and also found an earlier version on the suse 10 DVD. Basically I'm looking to use the IMAP server to centrally store emails on our home/business server. Previously we've been downloading mails (POP) from various mail accounts and moving them to dovecot (debian). In the future, I'd like to use fetchmail to do this part and locally deliver mail. My LDAP domain base is dc=aro,dc=home. I generally use this as the local mail/DNS domain as well. I have edited both /usr/local/etc/dovecot.conf and dovecot-ldap.conf. When I run dovecot it fails to start. I wonder if someone, in fairly broad ters could give me the steps for getting dovecot running with LDAP authenticated users? Regards Patrick

[Dovecot] cache
by Lucas 05 Nov '05

05 Nov '05

Hi, I just update from 0.99 to 1.alpha4. I combined with squirrel since several years ago and all was like a charm. Now dovecot is like catching mails. I explain: - I sent an email to my account. I login to webmail and I could see the mail. - Then, I check my mail with an email client through pop3 (vpopmail). - After that the mail isnŽt in the server, but in the webmail appears one msg in Inbox folder and the header. When click to see the msg an error ocurred: Query: FETCH 1 (FLAGS BODYSTRUCTURE) I try this in my config file: mail_never_cache_fields = flags date.sent date.received size.virtual size.physical mime.parts imap.body imap.bodystructure But no success :( Thank you in advance, Lucas

[Dovecot] forcing a default namespace
by Glenn Leavell 04 Nov '05

04 Nov '05

According to the Dovecot documentation, a "default namespace" is defined by simply configuring the namespace with an empty prefix, as in: namespace private { separator = / prefix = inbox = yes hidden = no } But my experience has been that this doesn't provide a true default, and that this namespace will only be selected when the client actually provides an empty ("") prefix. Is there a way to configure a default namespace that will always be chosen no matter what prefix the client provides, as long as there isn't an explicit match? I'd like to be able to have clients find mailboxes in a particular location no matter what they provide as their folder prefix.

[Dovecot] Dovecot 1.0a4 + pam + winbind ?
by Stephen Lee 04 Nov '05

04 Nov '05

Hi, I would like dovecot/pop3 to authenticate against a Windows ADS server. I've got authentication working for Samba and ssh using pam_winbind.so. Here's what my /etc/pam.d/dovecot file looks like: #%PAM-1.0 auth sufficient pam_winbind.so #auth required pam_nologin.so auth required pam_stack.so service=system-auth account required pam_stack.so service=system-auth account sufficient pam_winbind.so session required pam_stack.so service=system-auth session sufficient pam_winbind.so and this is what a portion of the dovecot.conf file looks like: auth default { # Space separated list of wanted authentication mechanisms: # plain digest-md5 cram-md5 apop anonymous mechanisms = plain passdb pam { args = dovecot } userdb passwd { } user = root } To get SSH to authenticate against ADS, the user name has to be prefaced with the domain name like "domain\user1". This is what I get when I attempt to login to Dovecot via Outlook/pop3 with the same naming scheme: Nov 3 20:09:45 server2 dovecot: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=192.168.0.3 rip=192.168.0.227 resp=AHZjXGpvYW5uZQBqb2FubmU= Nov 3 20:09:45 server2 dovecot: auth(default): plain(domain\user1,192.168.0.227): Username contains disallowed characters Nov 3 20:09:46 server2 dovecot: auth(default): client out: FAIL 1 user=domain\user1 Nov 3 20:09:46 server2 dovecot: pop3-login: Disconnected: user=<domain\user1>, method=PLAIN, rip=192.168.0.227, lip=192.168.0.3 Dovecot does not like the "\" character and I'm note sure authentication gets past that step to get to the pam phase. Any experiences and suggestions with Dovecot authentication against Windows Active Directory? Thanks, Stephen

[Dovecot] courier2dovecot migration script
by Arto Bendiken 03 Nov '05

03 Nov '05

Howdy, I've just migrated a couple of servers to Dovecot, and am loving it so far. I thought I'd share the courier2dovecot shell script I whipped together (based on the instructions I found in the wiki.dovecot.org migration how-to), for converting Courier-IMAP maildirs to Dovecot format. It can be downloaded from my home page: http://bendiken.net/scripts/ While the script is rather simple, it can save a fair bit of typing when migrating some hundreds of mail accounts... especially since Courier stores some of its own state files recursively in each folder of the maildir hierarchy, making it a real pain to otherwise manually rename or remove all of them. Here's a plain-English summary of what the script currently does, when given a Courier maildir path as an argument: - check that the given path is indeed a valid Courier maildir, and exit if not - rename the file 'courierimapsubscribed' to 'subscriptions', and strip the 'INBOX.' prefix from its contents - recursively rename all of files of the name 'courierimapuiddb' to 'dovecot-uidlist' - recursively delete all of files of the name 'courierimaphieracl', 'courierimapacl' and 'courierimapkeywords' The script will also verbosely print out each action it does, handy for redirecting the output to a log file for a large migration. I hope people about to jump ship from Courier to Dovecot find this useful. If anyone comes up with improvements to the script, please send them my way :-) Arto

[Dovecot] assertion problems w/ 1.0alpha4
by Jeremy Brown 03 Nov '05

03 Nov '05

Hey list, I have been using 0.99.14 for a while now but recently decided to try to upgrade to 1.0alpha4 to get the latest and greatest. I'm building from source myself on a Slackware 10.0 machine. Slackware ships with UW-IMAP configured to keep your inbox in /var/spool/mail and your other folders in ~/. I've been using the same setup for dovecot so that the migration is smooth...so my default_mail_env is set to: default_mail_env = mbox:~/:INBOX=/var/mail/%u I'm able to connect to both pop and imap servers and authenticate myself, but as soon as I attempt to get a listing of my emails my dovecot setting crashes with the following in the mail logs: Nov 3 10:52:40 shallowhal dovecot: imap(jeremy): file mail-index-sync-ext.c: line 155 (get_ext_header): assertion failed: (memcmp((char *)(ext_hdr + 1), ext->name, strlen(ext->name)) == 0) I can trigger this over POP3 just by logging in, then issuing "USER username", "PASS password", and then "LIST". Anyone experienced anything like this before? Any ideas on what might be going on? I can include more debug information (like my dovecot.conf file) if it would help. Jeremy

[Dovecot] How to log POP3 events
by Cliff Hayes 03 Nov '05

03 Nov '05

Hello all, Thanks for your help getting me started. I have Dovecot running now. When I troubleshoot customer email problems, I need to be able to see the number of emails they popped. In /var/log/maillog, Dovecot just tells me that they authenticated, but not what happened after they authenticated. With pop3d, I saw how many emails they popped. Can I set that in Dovecot? I checked the documentation and couldn't find anything. I also turned on the "auth_verbose = yes" and "auth_debug = yes" -- but as the name implies, I only got more authentication info. Nothing about files tranferred. Thanks, Cliff

[Dovecot] Vpopmail authentication problem
by [Mailclub] Laurent Bauer 03 Nov '05

03 Nov '05

Hello, I have a problem setting dovecot-1.0 / vpopmail authentication with virtual users. Here is my dovecot.conf (the part related to vpopmail) : passdb = vpopmail userdb = vpopmail default_mail_env = maildir:/home/domains/%d/users/%n I recompiled dovecot with "verbose" option and keep getting this error : Nov 3 11:10:58 ***** dovecot: auth(default): vpopmail(lb(a)mm.fr): unknown user (lb(a)mm.fr) whatever user/domain/password I am testing (including the correct one, of course) This is in src/auth/userdb-vpopmail.c line 35 : vpw = vauth_getpw(vpop_user, vpop_domain); According to the makefile, the binary was built with -L/home/vpopmail/lib and -I/home/vpopmail/include options ("standard" qmail/vmailmgr/vpopmail installation) so it should be ok ? I checked the permissions by setting a shell for vpopmail user, then 'su vpopmail' and read/write the password.cdb file. What could be wrong ? Has anybody got a sample config file / dovecot version working with vpopmail and virtual users, or an idea of what could be wrong in my config ? Thanks a lot. Laurent

Haven't used this for quite a while, so I don't know if I can really help you. > auth_userdb = passwd > auth_passdb = shadow Dovecot uses the homedir that's in your passwd then. But I wonder how you want to use IMAP. AFAIK, it needs a separate directory for every user anyway. At least the indexes etc. have to be stored somewhere. You should really read doc/mail-storages.txt: "mbox storage requires an IMAP root directory where to store IMAP folders and some other information..." I you can't provide a directory for every user, dovecot is probably not the software for you.

[Dovecot] Still corrupt indexes in 1A4
by Alen Salamun 02 Nov '05

02 Nov '05

Hello All! Well I still have users which almost daily get corrupt dovecot files in their IMAP folders (Maildir style) and are unable to read their mail in this particular folders. When I delete dovecot files in this folder (rm -rf dove*) user can again read all messages. This is regular Linux CentOS 4.2 with SAN storage (boot from SAN) as disks. So this is EXT3 on LVM. BUT it is VERY interesting that than happens only to two users which are connected to the server via slow links (reading via Thunderbird or Squirrelmail). It never happened (now for weeks) to other 10 users which use it localy or at home (on speedy links). It's very hard for me to exactly pinpoint the problem, since it never happens to me. But when it happened to one user again I asked him to send me screenshoot of it. I could see there that SquirrelMail said: "Warning: fgets() [function fgets]: SSL: fatal protocol error in /usr/share/squirrelmail/functions/imap_general.php on line 93." Examining this file this line is in function: --------SQUIRRELMAIL PHP SOURCE------------ /** * Custom fgets function: gets a line from the IMAP server, * no matter how big it may be. * @param stream imap_stream the stream to read from * @return string a line */ function sqimap_fgets($imap_stream) { $read = ''; $buffer = 4096; $results = ''; $offset = 0; while (strpos($results, "\r\n", $offset) === false) { if (!($read = fgets($imap_stream, $buffer))) {<- THIS IS LINE 93 /* this happens in case of an error */ /* reset $results because it's useless */ $results = false; break; } if ( $results != '' ) { $offset = strlen($results) - 1; } $results .= $read; } return $results; } } ------------------------------------------- Looks like dovecot drops connection or something. Well must be related to corrupt dovecot files in particular folder, since deleting them solves the problem. BR, Alen Salamun

[Dovecot] New Fedora/Sendmail Install Assistance
by Cliff Hayes 02 Nov '05

02 Nov '05

Hello everyone, I've narrowed down my problem, so this should be an easy one for some smart person out there. I am moving from an old sendmail/Fedora 2 box to a new sendmail/Fedora 4 box and want to try Dovecot for pop3. The problem is, I can't get it to work. I have 9000 email accounts I will be moving to the new box. I've already tried and failed once. The problem is, Dovecot wants a home directory for each one. We don't use home directories. So, when I try to pop one of the accounts that was moved over, /var/log/maillog shows: Nov 1 14:33:47 sendmail pop3(chayes): mkdir_parents(/home/chayes/mail/.imap/INBOX) failed: Permission denied Nov 1 14:33:47 sendmail pop3(chayes): Couldn't open INBOX: Internal error occured. Refer to server log for more information. [2005-11-01 14:33:47] -or- Nov 1 14:29:18 sendmail pop3(chayes): mbox: Can't create root IMAP folder /home/chayes/mail: Permission denied Nov 1 14:29:18 sendmail pop3(chayes): Failed to create storage with data: mbox:/var/spool/mail/chayes ******** But if I create folders /home/chayes/ and /home/chayes/mail with user and group set to chayes, then it works. By the way, I've tried about 20 different iterations of the default_mail_env parameter. This is the one I'm using at the moment: default_mail_env = mbox:/var/spool/mail/%u Bottom line is, if Dovecot has to have a home directory, then I guess I'll have to go back to pop3d, which doesn't. Thanks, Cliff

[Dovecot] 1.0.alpha4 released
by Timo Sirainen 02 Nov '05

02 Nov '05

The actual alpha4 release this time. With a few changes since the pre-release. The important changes again: - Default lock_method changed to flock instead of the old fcntl. Solaris users will need to set it back to fcntl. This makes sure that Dovecot's indexes aren't accidentally used with NFS. - IMAP: We might have sent extra EXPUNGE messages when output buffer got full. This could have caused various sorts of very bad behavior. This is the main reason why everyone should upgrade as soon as possible. - POP3: We sent duplicate replies for LIST command when output buffer got full. Probably caused Thunderbird's duplicate deletion bugs? (Although I thought someone checked that Dovecot's reply was correct when the bug occurred?) - pop3_uidl_format setting is now required to be explicitly set in configuration file for pop3 to work at all. I want to get rid of the old default setting which breaks Outlooks, and simply changing the default would break existing setups. - Multiple passdbs and userdbs of same type can now be added with different parameters. Some people asked about this earlier. - Authentication cache works now with other than SQL and LDAP passdbs. Some passdbs such as PAM require some additional settings to work. See example config file. - Some other fixes to authentication cache related to failure handling and non-plaintext authentication. - deny passdb wasn't working for non-plaintext authentication. New changes since alpha4 pre-release: - imap/pop3 proxy feature was broken - fixed an assert-crash in ostream-file.c that was only in the pre-release And some more changes since alpha3 that I didn't mention before: - zlib plugin updated in http://dovecot.org/patches/1.0/zlib-plugin.tar.gz to be much faster than before - Added ssl_username_from_cert setting. Not actually tested yet, does it work? - epoll was broken with 64bit systems - Added deny password databases. - Dovecot can be run from inetd again - Index breakage/crashfix related to adding new keywords

[Dovecot] Cannot build rpm with mysql support from dovecot.spec
by Erick Perez 02 Nov '05

02 Nov '05

I've been playing for hours with the dovecot.spec file to build --with-mysql. The resulting RPM builds fine but when dovecot runs it does not recognize the passdb mysql statement. I also noted that the spec file has a version of 1.0-stable and rpmbuild complains about an invalid '-' in the version. Being a newbie in rpmbuild, can someone assist me in building for CentOS 4 on i386? standard build options but --with-mysql added. I also tried to install it from sources and it does not work (at least for me). Being a RPM user now I have to clean what the source installation did and i have no clue where the 'make install' placed files. BTW I am trying to build a manual (pdf, html) with the following config and im only stuck with dovecot, the other daemons are ready. Target Server: CentOS 4 with apache, postfix, mysql, dovecot, openwebmail,clamav, clamd, php,zlib,openssh, webmin and samba. All virtual running from mysql where possible, no local users no local storage (all to the mysql db/tables). Not wanted: postgresql, courier,vpopmail,kerberos,sasl,ssl (that might be in manual v2.0 if 1.0 ever sees the light) The system does not have X (no need for fancy graphs) file used: http://www.dovecot.org/nightly/stable/dovecot-stable-20051102.tar.gz RPMs Used: All RPMs that can be located in the CentOS 4 CDs so new users (like me) can do as much as needed without downloading. Devel RPMs: All devel (mysql, pam, openssl) are installed and they are recognized at building time. Your help will be appreciated in this task.

[Dovecot] Problems with dual ldap auth
by Stian Jordet 01 Nov '05

01 Nov '05

Hi, I can't seem to figure this out. Is it impossible to use two different ldap auth? It works if I use one ldap and one pam, but I do need to use ldap for both. This is from my config: auth default { mechanisms = plain passdb ldap { args = /etc/dovecot/ldap-virtual.conf } passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } userdb ldap { args = /etc/dovecot/ldap-virtual.conf } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } user = root #chroot = #count = 1 #ssl_require_client_cert = no } It works well if I only use one of them (so they seem to be correct), but together, only the last (dovecot-ldap) is used. Anyone see a reason for that? Best regards, Stian

[Dovecot] Usernames and Passwords for Virtual Users Request
by Matt 01 Nov '05

01 Nov '05

A feature I think would be nice. When a single IP hosts email for multiple domains the solution is usually to use the complete email address as the username. I have users that have migrated from Cobalt RAQ's which do not work like that. If a user trys to authenticate with just there username such as "joeb" instead of joeb(a)dirt.com I would like Dovecot to check all the domains it hosts and if it only finds one with the username "joeb" assume thats the one. If multiple domains have the username "joeb" refuse to authenticate without the "@domain" part. Perhaps this is not possible. Sure would be handy though. Oh, it would also be nice to automatically lowercase all usernames before authentication. Matt

[Dovecot] popa3d migration problem
by Janusz Batko 01 Nov '05

01 Nov '05

Hello, I tried to migrate from popa3d to dovecot but I couldn't manage with 'pop3_reuse_xuidl = yes' option. First of all it turned out that the feature is not supported in dovecot for Fedora Core 4 (dovecot-0.99.14-4.fc4). So I downloaded latest stable release of Dovecot but it didn't have this option included too. Then I compiled the newest alpha version (dovecot 1.0.alpha4) and I tried to login with 'pop3_reuse_xuidl = yes' option enabled and I've got in my logfile the following output: Nov 1 00:58:33 sneogg dovecot: pop3-login: Login: user=<test2>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Nov 1 00:58:33 sneogg dovecot: pop3(test2): Set pop3_uidl_format setting in config file Nov 1 00:58:33 sneogg dovecot: child 32067 (pop3) returned error 89 And my session was disconnected immediately each time after sucessful authentication.. I tried to set up pop3_uidl_format to MD5 (%m) but it didn't work... Let me ask if there is a possibility to migrate from popa3d to dovecot (by using a proper patch maybe?)? I'd thankful for any response... Janusz

[Dovecot] Dovecot Alpha 4
by Marcus Don 30 Oct '05

30 Oct '05

Hi We've been using Dovecot as our primary IMAP and POP3 server for around 70,000 users for a couple of months now. On the whole, we've been very pleased with the performance of Dovecot - and are extremely grateful to the developers! However, we have had a few issues, some of which we have yet to resolve. We chose Dovecot because it was the only IMAP/POP3 server we could find that supported direct mysql authentication and both mboxes and maildirs. With exim as our main SMTP server, we were able to convert the inboxes and imap folders for all 70,000 users from mboxes to maildirs without any downtime whatsoever! For those who are interested, we have a cluster of 5 web/imap servers (running our own webmail software) and a further 5 pop servers all placed behind 2 Zeus load balancers and running RHEL 4 (actually CentOS 4.1). Storage is provided by an EMC Clariion device, which is mounted via NFS onto all servers in the cluster over gigabit ethernet. 1. index files The main problem has always been the index files becoming corrupted. This seems to have improved with the Alpha 4 release, but still happens for several users each day. Perhaps it would be possible for Dovecot to just delete index files and re-create them when they are corrupted, rather than just erroring? Also, how do you turn off index files altogether? Even when mail_never_cache_fields is set for all available fields, they still get created. Another issue relating to the index files is that, if a user is deleted and then another user created with the same name, dovecot doesn't have permissions to re-write the index files, because it has a different uid. So, whenever a user is deleted, we have to delete the index files from every machine in the cluster. We could store index files on the NFS device, but this would affect performance (and might cause locking problems). A better solution would be to make the uid one of the variables available in default_mail_env. By naming index files by uid rather than username, this wouldn't be an issue. 2. initgroups() We use an nss-mysql to store all non-administrative system users in a mysql database. We often encounter problems with applications that use the initgroups() function, since this returns all users and groups - which in our case returns masses of data from mysql. When using mysql (or ldap etc) for authentication, it would be useful if there were an option to prevent additional system lookups. At present, we have to comment out the following in /src/lib/restrict-access.c, or the server load goes through the roof: if (initgroups(env, gid) != 0) { i_fatal("initgroups(%s, %s) failed: %m", env, dec2str(gid)); } 3. base_dir permissions bug Since the alpha 4 release, it seems that the permissions dovecot automatically sets for the base_dir are not sufficient to allow the authentication user to access sockets, unless this user belongs to the same group as the login user - which is contrary to the instructions in the documentation. I'm pretty sure this is a bug, but perhaps someone could confirm. 4. authentication caching Also since the alpha 4 release, we have found that, once the authentication cache is full, all subsequent login attempts for users that haven't been cached return "password mismatch". I though this might be a conflict with nscd, but it happens whether nscd is running or not. So, for the time being, we have had to disable the authentication cache. I'd be very keen to hear from anyone who has any feedback on any of the points above.

[Dovecot] Dovecot reports zero messages erroneously
by Chris Spiegel 29 Oct '05

29 Oct '05

On October 11, Mark Farmer reported a problem about not being able to see new mails. I'm running into the same issue. Even though cur/ and new/ contain messages, Dovecot reports that there aren't any. This problem seemed to start happening in alpha3 (and persists in alpha4). When I revert back to alpha2, the messages show up again. It looks like a problem with the dovecot.index* files. When I delete them, alpha4 can serve up the mails just fine, and will in fact keep working for a little while. Eventually (within a few hours, although I'm not sure what causes it), dovecot thinks things are empty again. Like Mark, I'm using Postfix.. I'm not sure if that has anything to do with the problem but I thought it'd be worth pointing out. If there are any specific things you'd like me to do to try to pin down this problem, let me know.

[Dovecot] Some errors with 1.0.alpha4
by Nicolas STRANSKY 29 Oct '05

29 Oct '05

Hi, I'm getting three types of errors with latest Dovecot compiled for x86_64 GNU/Linux Debian. Oct 29 12:47:57 rouge imap-login: unable to dlopen /usr/lib/sasl2/libntlm.so.2: /usr/lib/sasl2/libntlm.so.2: failed to map segment from shared object: Cannot allocate memory Oct 29 12:47:57 rouge pop3-login: unable to dlopen /usr/lib/sasl2/libntlm.so.2: /usr/lib/sasl2/libntlm.so.2: failed to map segment from shared object: Cannot allocate memory I have no idea why there is this error, but it comes each time a user logs in, with no other severe effect. Oct 29 01:28:54 rouge dovecot: imap(glondu): pool_system_malloc(): Out of memory Oct 29 01:28:54 rouge dovecot: child 5642 (imap) returned error 83 (Out of memory) Oct 29 01:38:10 rouge dovecot: imap(glondu): pool_system_malloc(): Out of memory Oct 29 01:38:10 rouge dovecot: child 5639 (imap) returned error 83 (Out of memory) Oct 29 01:49:22 rouge dovecot: imap(glondu): pool_system_malloc(): Out of memory Oct 29 01:49:22 rouge dovecot: child 8839 (imap) returned error 83 (Out of memory) The mailbox for this user is not bigger that 10MB and dovecot mail_process_size is set to default setting so I don't see why there could be a "Out of memory" error. Oct 28 18:00:45 rouge dovecot: imap(vidal): Lost transaction log file /var/dovecot-indexes/vidal/.INBOX/dovecot.index.log seq 1 Oct 28 18:00:45 rouge dovecot: imap(vidal): Lost transaction log file /var/dovecot-indexes/vidal/.INBOX/dovecot.index.log seq 1 Oct 28 18:00:56 rouge dovecot: imap(vidal): Lost transaction log file /var/dovecot-indexes/vidal/.INBOX/dovecot.index.log seq 1 Oct 28 18:00:56 rouge dovecot: imap(vidal): Lost transaction log file /var/dovecot-indexes/vidal/.INBOX/dovecot.index.log seq 1 This error caused the user's mailbox to be unreadable, and erasing the indexes resolved the problem, but I would have expected Dovecot to have done it itself if the indexes were corrupted ? Hope this feedback helps, -- Nico

[Dovecot] Basic Configuration
by Ashvin Meetoo 29 Oct '05

29 Oct '05

Hi, Been setting up a backup mail server just in case... using FC4... basic configuration... postfix/dovecot... imap pop3... When I send an external email, example(a)gmail.com, everything works well. When I send an internal email, i.e. to another user, user receives a blank email? Everytime he clicks on get mail a new empty email is added... checked /<user>/Mailbox/new folder email is there and header is ok. What can be the matter? Did this thousand times before and even reinstalled FC4... same problem. Also, I have tried: echo test | mail root but mail gives me : No mail for root Help please. __________________________________ Yahoo! Mail - PC Magazine Editors' Choice 2005 http://mail.yahoo.com

[Dovecot] dovecot-lda cvs
by Rene Luria 28 Oct '05

28 Oct '05

I am using dovecot-lda from cvs (checked out on september the 21st) and dovecot 1.0alpha2 (not yet upgraded ok). I have a strange feeling about "redirect" feature. Let's see two sieve scripts examples: # ex1 require ["fileinto", "vacation"]; if header :is ["blabla"] "blabla" { fileinto "blabla"; } redirect "user(a)domain.com"; keep; # ex2 require ["fileinto", "vacation"]; redirect "user(a)domain.com"; keep; In both cases, I redirect mail to an external address, keeping a copy. (this would emulate redirect :copy "user(a)domain.com"; which is still not implemented). In first example I run a test on headers, but not on the second. The effect is that in the second example, the forwarded mail is "complete" (exactly the original one with routing header modified), but in the first one, the forwared mail is completely messed up: no Subject header, and so on. This could be because as tests are run on the incoming mail, the working in memory of the mail is changed, and then, forwarded. So when no tests are run, the mail remains intact. How can I deal with this ? Is there some nice hotfix that would prevent a few (like 100'000) users to kill me ? Best regards. -- Rene Luria

[Dovecot] 1.0.alpha3 plaintext authentication problem
by Sergey Redin 28 Oct '05

28 Oct '05

Hello everyone, Since the upgrade to 1.0.alpha3 I experience a strange problem with plaintext authentication. I successfully login first few (2-5) times after the dovecot restart, and then on a reason I cannot login any more (both via POP3 and IMAP). I tried to find out what could be the reason for this but I failed. Nothing is changed inside the user's home directory or /var/run/dovecot, but I cannot login any more. I guess there is something wrong inside dovecot-auth od dovecot process itself. I just start to receive "01 NO Authentication failed." or "-ERR Authentication failed." from dovecot and "Authenticate PLAIN failed: Unsupported authentication mechanism.: method=PLAIN" in my logs, even though I used the same PLAIN two minutes ago without a problem. Here is my dovecot.conf: nevoservice# egrep -v '^[ ]*(\#.*)?$' /usr/local/etc/dovecot.conf protocols = imap pop3 ssl_disable = no ssl_cert_file = /etc/mail/certs/server.crt ssl_key_file = /etc/mail/certs/server.key disable_plaintext_auth = no log_path = /var/log/dovecot/log info_log_path = /var/log/dovecot/info login_user = dovecot login_processes_count = 1 verbose_proctitle = no first_valid_gid = 0 mail_extra_groups = mail mail_debug=yes default_mail_env = mbox:/var/mail/%u maildir_copy_with_hardlinks = yes protocol imap { imap_client_workarounds = delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep } protocol pop3 { pop3_uidl_format = %08Xu%08Xv pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } auth_verbose = yes auth_debug = yes auth default { mechanisms = plain passdb passwd-file { args = /usr/local/etc/dovecot.passwd } userdb passwd-file { args = /usr/local/etc/dovecot.passwd } user = root } Here are two lines in dovecot.passwd which define the user that I use: wail:password-hash:1050:1032:Administrator wail.spb.ru:/home/wail.spb.ru:::/var/mail/wail wail@nevoservice.ispvds.com:password-hash:1050:1032:Administrator wail.spb.ru:/home/wail.spb.ru:::/var/mail/wail A few lines from my /var/log/dovecot/info file: dovecot: Oct 10 02:03:11 Info: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=82.146.50.34 rip=82.146.63.23 resp=AHdhaWwAVGxNSFRuUlI2 dovecot: Oct 10 02:03:11 Info: auth(default): client out: OK 1 user=wail dovecot: Oct 10 02:03:11 Info: auth(default): master in: REQUEST 3 53919 1 dovecot: Oct 10 02:03:11 Info: auth(default): master out: USER 3 wail uid=1050 gid=1032 home=/home/wail.spb.ru mail=/var/mail/wail dovecot: Oct 10 02:03:11 Info: pop3(wail): Effective uid=1050, gid=1032 dovecot: Oct 10 02:03:11 Info: pop3(wail): maildir autodetect: stat(/var/mail/wail/cur) failed: Not a directory dovecot: Oct 10 02:03:11 Info: pop3(wail): mbox autodetect: data=/var/mail/wail dovecot: Oct 10 02:03:11 Info: pop3(wail): mbox autodetect: INBOX file: yes (/var/mail/wail) dovecot: Oct 10 02:03:11 Info: pop3(wail): mbox: data=/var/mail/wail dovecot: Oct 10 02:03:11 Info: pop3(wail): mbox: root exists (/home/wail.spb.ru/mail) dovecot: Oct 10 02:03:11 Info: pop3(wail): mbox: root=/home/wail.spb.ru/mail, index=/home/wail.spb.ru/mail, inbox=/var/mail/wail dovecot: Oct 10 02:03:11 Info: pop3-login: Login: user=<wail>, method=PLAIN, rip=82.146.63.23, lip=82.146.50.34 dovecot: Oct 10 02:03:13 Info: pop3(wail): Logout. top=0/0, retr=0/ del=0/3, size=5372 dovecot: Oct 10 02:03:20 Info: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=82.146.50.34 rip=82.146.63.23 resp=AHdhaWwAVGxNSFRuUlI2 dovecot: Oct 10 02:03:20 Info: auth(default): client out: OK 1 user=wail dovecot: Oct 10 02:03:20 Info: auth(default): master in: REQUEST 4 53918 1 dovecot: Oct 10 02:03:20 Info: auth(default): master out: USER 4 wail uid=1050 gid=1032 home=/home/wail.spb.ru mail=/var/mail/wail dovecot: Oct 10 02:03:20 Info: pop3(wail): Effective uid=1050, gid=1032 dovecot: Oct 10 02:03:20 Info: pop3(wail): maildir autodetect: stat(/var/mail/wail/cur) failed: Not a directory dovecot: Oct 10 02:03:20 Info: pop3(wail): mbox autodetect: data=/var/mail/wail dovecot: Oct 10 02:03:20 Info: pop3(wail): mbox autodetect: INBOX file: yes (/var/mail/wail) dovecot: Oct 10 02:03:20 Info: pop3(wail): mbox: data=/var/mail/wail dovecot: Oct 10 02:03:20 Info: pop3(wail): mbox: root exists (/home/wail.spb.ru/mail) dovecot: Oct 10 02:03:20 Info: pop3(wail): mbox: root=/home/wail.spb.ru/mail, index=/home/wail.spb.ru/mail, inbox=/var/mail/wail dovecot: Oct 10 02:03:20 Info: pop3-login: Login: user=<wail>, method=PLAIN, rip=82.146.63.23, lip=82.146.50.34 dovecot: Oct 10 02:03:21 Info: pop3(wail): Logout. top=0/0, retr=0/ del=0/3, size=5372 dovecot: Oct 10 02:03:28 Info: pop3-login: Authenticate PLAIN failed: Unsupported authentication mechanism.: method=PLAIN, rip=82.146.63.23, lip=82.146.50.34 dovecot: Oct 10 02:03:30 Info: pop3-login: Aborted login: method=PLAIN, rip=82.146.63.23, lip=82.146.50.34 We see here two successfull logins with PLAIN and then suddenly PLAIN becomes unsupported.

[Dovecot] Corrupted index cache file [...] invalid record size
by Lorens 28 Oct '05

28 Oct '05

I get this error every single time some of my users log in: Error: POP3(${user}): Corrupted index cache file /${userdir}/dovecot.index.cache: invalid record size The named file seems to be deleted as soon as corruption is found. This only affects some users. I thought the affected users had in common that they are using POP3 in "leave-messages-on-server" mode, and that their mailboxes are big ( > 100 MB). However I've found a few counterexamples, few and far between (not every login) but still. Google's no help, for once :-) Could this be a locking problem, a bug with big Maildirs (counterexamples being few), or what? I know some of my users have had problems logging several IMAP clients into the smae account at the same time, wouldn't put it past some of those with problems to be trying the same with POP. I know that a detected cache corruption is merely that, but I find the error message annoying :-) Configuration: v1.0-stable (0.99.20050712-2 from debian unstable) Maildir only Default locking (nothing mentioned in conf file) Access over NFS mmap_disable = yes (wiki says to disable mmap to use indexes on NFS). Thanks for any pointers.

[Dovecot] hangup with corrupted indexes
by Sergey Redin 28 Oct '05

28 Oct '05

Hello everyone, I remember that Timo wrote in this maillist that if index files are corrupted, dovecot should be OK and just recreate it. So I report here a bug: I have corrupted indexes which make pop3 and imap processes to hangup right after the first list command. The process does not respond and eats 90% of CPU. Just unpack http://redin.info/dovecot-corrupted-index.tgz (10 Kb) into a user's IMAP root (I have mbox storage, but the same thing for maildir with this indexes), do the chown, and try to check the email. I know that the problem can be fixed by removing the index files or using INDEX=MEMORY, but it is claimed that dovecot is failsafe and can deal with any kind of corrupted index files. This is the only reason why I report it here. I have 1.0.alpha4 on FreeBSD 4.11 (installed from ports). Best regards, Sergey Redin.

[Dovecot] Weirdness with authentication/1.0a4.
by Ashley Penney 28 Oct '05

28 Oct '05

Hi, FreeBSD has recently upgraded their port from 0.99 to 1.0a4, and this has caused me an absolute nightmare of a situation. In a nutshell I replaced my conf with the -example, and modified almost nothing. I made some SSL certs and put them in place, left it with imap/pop/pam etc. Whenever users tried to connect to the remote address, cara.untaken.net, I would get: Oct 27 18:31:14 cara dovecot: Dovecot v1.0.alpha4 starting up Oct 27 18:31:33 cara dovecot: imap-login: Login failed: Plaintext authentication disabled: rip=217.206.62.50, lip=217.206.62.50 Oct 27 18:31:33 cara dovecot: imap-login: Disconnected: rip=217.206.62.50, lip=2 17.206.62.50 However, plaintext authenication was most definitely not disabled. Using www.untaken.net/mail/ which is hosted on the same box as dovecot I could get this plaintext failure constantly using cara.untaken.net, but switching to 'localhost' instead would work fine, despite being the same physical machine. I'm baffled at what could cause this, I put my currently conf over at www.untaken.net/dovecot/ just for reference, I've modified various bits now from the default in a desperate attempt to get it working. Has anyone else seen anything like it? -- <EisernLint> i am considering taking pilates classes.
