[Dovecot] index performance issues
by Netserve 13 Mar '07

13 Mar '07

Running 1.0.rc22 We have a single file server, running NFS (Single large sas disk) with about 80Gb of mail. mount -o remount,rsize=2048,wsize=2044,actimeo=0,soft,rw xx.xx.xx.xx:/mailboxes /nfs1 There are 3 front end pop/imap servers using an LVS director. Indexes are stored on each front end server. -rw------- 1 admin 500 144 Mar 12 17:47 dovecot.index -rw------- 1 admin 500 10272 Mar 12 17:47 dovecot.index.cache -rw------- 1 admin 500 120 Mar 12 17:47 dovecot.index.log Normally everything runs fine, there are about 1500 active pop accounts and 100 Imap. Typically, 10 to 20 pop accounts are downloading at anyone time, and there may be 10 or 20 active Imap sessions. If we find that the index partition has got to 100% full and corrupted the indexes then we'll delete the entire index dir and let dovecot rebuild all the indexes however, we end up with 100mbit / 10Mb/sec of network traffic between the NFS server and the pop/imap servers. The nfs server load climbs to 20+ as does the load on the front end mail servers. It can take 4 or 5 hours for the indexes to rebuild during which time imap is slow but works and pop downloads all end up with dead processes that need clearing every few minutes. admin 5869 0.0 0.1 4384 1060 ? D 17:56 0:00 \_ pop3 [info@.co.uk 180.98] admin 5877 0.0 0.1 4392 1112 ? D 17:57 0:00 \_ pop3 [bro94 62.182] admin 5879 0.0 0.1 4396 1052 ? D 17:57 0:00 \_ pop3 [spamcatch@.com 81.163] admin 5884 0.0 0.1 4392 1056 ? D 17:57 0:00 \_ pop3 [ctaylor@.com 81.175] Normally the nfs server delivers possibly 200Kbytes of traffic average spiking to 400Kbytes but the 900+Kbytes per second sustained rate for 5 or 6 hours is killing the service. Is there something we've got wrong here? (I know a Scsi raid NFS would help as would Gbit networking but I can't see the setup we've got as needing that sort of hardware spec?) Thanks John

[Dovecot] imap + unmounted home disk
by T. Horsnell 13 Mar '07

13 Mar '07

dovecot 0.99 still (RHEL4), I'm sorry to say. The config is for mbox's to live on the user's home disk. If the user tries to make an imap connection when his home disk is unmounted, various permission denied messages are logged, as expected, but then the imap process seems to hang around instead of aborting. The result is that eventually the imap process limit is reached, and even those users whose home disks are correctly mounted, cant get at their mail. Apologies if this has already been fixed - I cant find anything relevant in the archives. Cheers, Terry

[Dovecot] Password encoding
by David Mills 13 Mar '07

13 Mar '07

Hi, I've currently got a problem authenticating to my dovecot server (1.0rc15). The server is set up to authenticate against a mysql server, with a default password scheme of 'crypt'. The problem is that some of the passwords I need to transfer (all from /etc/shadow files) are md5 encoded, and when I put {md5-crypt} in front of the password to force the scheme, dovecot answers :"Unknown password scheme md5-crypt". If anyone has any ideas, I'd really appreciate it. TIA for your time.

[Dovecot] Problems fetching mail
by Curt LeCaptain 13 Mar '07

13 Mar '07

I'm attempting to replace UW-IMAP with Dovecot, as my UW-IMAP implementation seems to be not working very well. Here's the problem I had with UW-IMAP: In Horde/IMP, messages just wouldn't appear at all. If I opened up the user's IMAP box via an IMAP client, I'd get a Bogus sequence in UID fetch error. So, now I've got Dovecot in place, and I'm getting the following error upon attempting to look at this same box: Error in IMAP command UID: Invalid UID messageset. Now, this user has 3 messages, each X-UID increments by one, starting at 1, so: X-UID: 1 X-UID: 2 X-UID: 3 None of those seem out of the ordinary size wise. I'm not sure what config information you'll need of me, as I'm new to dovecot, but any help would be appriciated. Thanks, Curt L.

[Dovecot] Quota and Trash
by Bernhard Schmidt 12 Mar '07

12 Mar '07

Hi, I finally got a grip on our mail guys to try out Dovecot after they started migrating a ~15k user mailsystem to Maildir+NFS (Netapp)+Courier and the performance was not as good as expected. So far the results are impressive, although there are of course a few small issues to be solved. One is the current Quota handling, which they use with Courier IMAP and (still) think it needs to be replicated 1:1 to dovecot. Currently they use maildir++ quota format. Mails moved to Trash get not included in the Quota calculation (standard "feature" of Courier IMAP) and get expunged after a certain period of days (IMAP_EMPTYTRASH). Is there any way we could replicate this behaviour with Dovecot? Not including mails in the Trash-folder into quota calculation seems to be a no-go to me according to the documentation, you can ignore the quota limit when copying messages into a certain folder with the "ignore" keyword but they are still included. This issue is directly related with the second one. Deleting old mails in Trash could be archieved with the expire-plugin, but that does not work with Dovecot v1.0, and I'd definitely want to run this. So I have to use "find", which deletes the mail from the folder. However, those mails are still included in the Quota calculation, so that will very likely become incorrect. Is there a generic recommendation for a tool that could be used to rebuild maildir quota calculations? Any other ideas how I could solve this problem and have dovecot behave like Courier here? Thanks, Bernhard

[Dovecot] 1.0.rc26 released
by Timo Sirainen 12 Mar '07

12 Mar '07

http://dovecot.org/releases/dovecot-1.0.rc26.tar.gz http://dovecot.org/releases/dovecot-1.0.rc26.tar.gz.sig Most importantly this should fix mbox problems in recent RCs. * Changed --with-headers to --enable-header-install * If time moves backwards only max. 5 seconds, sleep until we're back in the original present instead of killing ourself. An error is still logged. - IMAP: With namespace prefixes LSUB prefix.* listed INBOX.INBOX. - deliver: Ignore mbox metadata headers from the message input. X-IMAP header crashed deliver. - deliver: If mail_debug=yes, drop out DEBUG environment before calling sendmail binary. Postfix's sendmail didn't really like it. - mbox: X-UID brokeness fixes broke rc25 even with valid X-UID headers. Now the code should finally work right. - Maildir: When syncing a huge maildir, touch dovecot-uidlist.lock file once in a while to make sure it doesn't get overwritten by another process. - Maildir++ quota: We didn't handle NUL bytes in maildirsize files very well. Now the file is rebuilt when they're seen (NFS problem). - Index/view handling fix should fix some crashes/errors - If index files were moved to a different endianess machine, Dovecot logged all sorts of errors instead of silently rebuilding them. - Convert plugin didn't change hierarchy separators in mailbox names. - PostgreSQL authentication could have lost requests once in a while with a heavily loaded server. - Login processes could have crashed in some situations - auth cache crashed with non-plaintext mechanisms

12 Mar '07

In Postfix+Postfixadmin+Dovecot+SASL+MySQL case what is the best and compact MySQL database structure for storing all configuration? What will you suggest me guys? I've already installed postfixadmin and I'm confusing (actually my experience is not enough) extending and organizing my database for postfix+dovecot. Please give me some quick tips. -- Best regards, Erdenebat Guntomor/ /mailto:RkLogin@gmail.com

[Dovecot] Time moving backwards error
by Matthew Ward 12 Mar '07

12 Mar '07

I'm currently running a VPS which has the NTP daemon running on neither my CentOS installation nor on the hardware node itself, so as far as I am aware the server time shouldn't be being resynched by anything, and the time should be consistent. However, since r25 my Dovecot service is complaining that time is moving backwards (was being killed only a few moments after being started with r25, same problems as Emmett with r26) quite consistently, and always by one second. Could this simply be an error or something within Dovecot itself, as to have nothing physically updating the system time on my machine at all and to have Dovecot complaining that it's being resynched by one second all the time seems a bit odd?

[Dovecot] dovecot and pine tab-completion
by Kyle Wheeler 11 Mar '07

11 Mar '07

Hello, So, I'm migrating from Binc to Dovecot, and one of my users has run into an odd complaint/issue. I don't know that it's a Dovecot issue necessarily, but maybe the people here know a fix anyway... The problem is that pine tab-completion now appends a "." to the end of folders that have sub-folders. In other words, say the user has these folders: INBOX INBOX.foo INBOX.foo.bar When he types in INBOX.f and hits tab, for some reason Pine completes that to: INBOX.foo. Note the "." on the end. This is annoying, because then to get into foo he has to hit the delete key first. With the Binc server, the delimiter was /, and INBOX/foo/ was a perfectly legitimate folder name (so he could just hit return). Does anyone have any suggestions for how to fix this? ~Kyle -- There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo. Please use in that order. -- Ed Howdershelt

[Dovecot] logging volumes
by Kyle Wheeler 10 Mar '07

10 Mar '07

Hello! I’m in the process of migrating from BincIMAP to Dovecot, and I have a minor question. One of the things that Binc does is logs how many bytes of data it has sent as part of logging the log-out. Is there a way to get Dovecot to do that, or to calculate something similar? ~Kyle -- Racism is man's greatest threat to man---the maximum of hatred for a minimum of reason. -- Abraham Joshua Heschel

Dovecot successfully reads the LDAP attributes for the user dvtest, however, the LDAP bind fails with "invalid credentials", yet, dvtest was allowed to login. The reason is simple: When I was testing the LDAP bind stuff, I "commented out" the user dvtest in /etc/passwd, but not in "/etc/shadow" and intentionally used another password in LDAP. Dovecot is configured to consult userdb/passdb ldap, first, then pam. In my case, the LDAP bind failed, so Dovecot fall back to pam - just as configured. I would like suggest to log wich passdb / userdb Dovecot gathered the information from, because, at first, I interpreted the log file as if Dovecot allows an user to login, who is not authentificated.

[Dovecot] Vexim with LDA delivery
by Chris Wopat 09 Mar '07

09 Mar '07

No support help needed, just a success report having Dovecot integrate with Vexim (exim with web based frontend and sql db): http://silverwraith.com/vexim/ Just wanted to forward some configs to the list if anyone finds them useful. I just switched from vexim's normal "virtual_delivery" to "dovecot_virtual_delivery" so I could use sieve, which works nicely with Horde. This is mostly as described on the wiki: http://wiki.dovecot.org/LDA I'm using maildirsize in my case. There were a few things that had to be done to get it to work with quotas, I thought I would just spell it all out for anyone reading this list in the future: I can add stuff if anyone would like to the wiki, some of these items are elsewhere in the wiki, I wanted to ask before I put a full page up for integration with Vexim in particular. Should I do this, or just throw bits and peices where they seem relevant? This was on FreeBSD, hence the /usr/local/etc/ stuff. Exim's 'configure' file: ================================ virtual_domains: #file_transport = virtual_delivery file_transport = dovecot_virtual_delivery virtual_domains_catchall: #file_transport = virtual_delivery file_transport = dovecot_virtual_delivery dovecot_virtual_delivery: driver = pipe command = /usr/local/libexec/dovecot/deliver -d \ $local_part@$domain message_prefix = message_suffix = delivery_date_add envelope_to_add return_path_add log_output user = mailnull dovecot-sql.conf: ================================ driver = mysql connect = host=HOSTNAME dbname=vexim user=vexim password=PASSWORD default_pass_scheme = CRYPT password_query = SELECT crypt as password FROM users,domains \ WHERE users.username = '%u' AND users.enabled = '1' \ AND users.type='local' and domains.enabled='1' \ AND domains.domain_id = users.domain_id user_query = SELECT pop AS home, 26 AS uid, 26 AS gid, \ CONCAT('maildir:storage=', quota*1024) AS quota \ FROM users WHERE username = '%u' AND enabled = '1' Mostly complete dovecot.conf (much of this is obvious, but it's easier than piecing things together from various mailing lists posts/docs): ================================ mail_location = maildir:%h/Maildir first_valid_gid = 26 last_valid_gid = 26 protocol lda { mail_plugins = quota } auth default { mechanisms = plain passdb sql { args = /usr/local/etc/dovecot-sql.conf } userdb sql { args = /usr/local/etc/dovecot-sql.conf } user = root socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = mailnull group = mail } } } plugin { quota = maildir } ================================ --Chris

[Dovecot] global_script_path and virtual users

We have a big installation with postfix + dovecot + sieve. Now we would like to create a "junk" folder in every customer inbox so they can discard the spam by they own. We are planning to user global_script_path = /etc/dovecot/dovecot.sieve Where /etc/dovecot/dovecot.sieve is: require "fileinto"; if exists "X-Spam-Flag" { fileinto "Junk"; } My question is, will the script find the users in our database? And how, will it be using the lda configuration? I have been for weeks looking for this in the wiki and couldn't find it anywhere. I promise I'll put it in there if I find the clue :)

From the Windows XP machine, all is ok, but from the Pocket PC a weird thing happens: When I first configure the client, in the Received Items, it shows all items correctly, but then, when starting to donwload, they simply disappear. All other folders are OK. Problem is just in inbox. I thing (although my tests were not exaustive) that deleting the .imap folder solves the problem, but I just can't understand why, because it is recreated again... Any help?

[Dovecot] "ldap_result() failed: Can't contact LDAP server" log messages

Greetings - I', continuing to build a test system that, at present, only I have access to. It is running Dovecot 1.0rc24. Here's the output of a "dovecot-n"... # /usr/local/etc/dovecot.conf log_path: /logfiles/mail/live/dovecot protocols: imap ssl_cert_file: /usr/local/etc/ssl/certs/imapservice-bundle.crt ssl_key_file: /usr/local/etc/ssl/private/imapservice-private.key disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login login_process_per_connection: no login_greeting_capability: yes mail_location: maildir:/mailstore/%1u/%u/Maildir:INDEX=/var/dovecot/ index/%1u/%u:CONTROL=/var/dovecot/control/%1u/%u mail_debug: yes mmap_disable: yes maildir_copy_with_hardlinks: yes mail_log_prefix: %Us(%u)[%p]: imap_client_workarounds: delay-newmail outlook-idle namespace: type: private separator: / inbox: yes auth default: mechanisms: plain login cache_size: 1024 cache_ttl: 600 username_chars: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890 username_format: %Lu passdb: driver: ldap args: /usr/local/etc/dovecot-ldap-passdb.conf userdb: driver: ldap args: /usr/local/etc/dovecot-ldap-userdb.conf We are using LDAP for the passdb and userdb.

The LDAP server *is* available throughout. I'm wondering if Dovecot is trying to hold the connection open but, after a timeout of 5 minutes of inactivity, the LDAP server is closing it and causing Dovecot to log this message. If this is indeed the case then I guess on a production server these message will be rarely if ever seen. Obviously I'd prefer not to have such worrying-sounding log entries appearing. (And if my guess is right then they're slightly misleading: the LDAP server *can* be contacted!) Any thoughts?

Everything else works as expected (eg, further userdb lookups based on certificate CN). Our University has issued a few thousand certificates with subjects such as "/C=GR/O=Aristotle University of Thessaloniki/OU=Network Operations Center/CN=Apostolos Papayanakis/emailAddress=apap/ at /ccf.auth.gr", that are used for administrative purposes. We would be very happy to use them as an alternative method of IMAP/POP3 authentication. However certificate CNs are not unique (e.g. "John Smith") and we would like to avoid constantly patching dovecot to use the email (or other) attribute from the certificate. I think replacing NID_commonName with NID_pkcs9_emailAddress ( or NID_subject_key_identifier, or NID_subject_alt_name) in login-common/ssl-proxy-openssl.c, line 527 would suffice. (X509_NAME_get_text_by_NID(X509_get_subject_name(x509), NID_commonName, buf, sizeof(buf)) < 0). Maybe I should post a complete patch if Timo is interested. Apostolis

[Dovecot] Seen this behavior before?
by hadmut＠danisch.de 09 Mar '07

09 Mar '07

Hi, it's not yet a bug report, just a question: After I was successfully using dovecot-imap and Thunderbird for quite a while without any problem (debian unstable), I now sometimes experience that the IMAP-connection hangs and thunderbird waits forever when accessing a folder. I did not yet analyze the problem and I am not sure whether it is a thunderbird or a dovecot problem. Did anyone see this behavior before? regards Hadmut

[Dovecot] any way to find last login time?
by Aleksey Perov 09 Mar '07

09 Mar '07

Hi, For some reason I need to regularly check which mailboxes are in use and which are not. For POP3, I use my patched version of popa3d which updates mtime on ~/Maildir/cur/ every time user logs in, and I always have a reliable way to find active and inactive mailboxes. Is there any way to find a last login time without parsing logs with dovecot? -- Aleksey

Hi all, Timo wrote in a message to the list in February that "%m variable expands to the auth mechanism name.". Indeed, the Wiki "Variables" page states that this is the case. However if I use %m in my SQL password query it does not get expanded. I'm using rc 25. What am I doing wrong?

[Dovecot] Message mixing after switchover from mbox to maildir
by Andrey Falko 09 Mar '07

09 Mar '07

Hi everyone, Here is the story. We are running Redhat Enterprise Linux 4, and were using Dovecot .99.x . At one point, we chose to switch from mbox to maildir (and still use Dovecot). After the switchover our users reported a bug when using Thunderbird: "A new behavior that I have observed a couple of times is that the new IMAP server confuses email headers with content. E.g., I have an email from Person X, but when I go to view it, the contents is just a spam body from an adjacent header. With this specific bug, adjacent spams are also running into other bodies. This occurs I'd say once every hundred messages. Other appearances of this bug are with adjacent messages concatenated. I'm not sure how to explain this, maybe what happens is that the new IMAP server confuses requests and delivers the wrong message bodies to the client, which get cached. This could in some circumstances be more than an annoyance, e.g., with confidential emails inadvertently getting picked up in replies to people outside the company." We proceeded to update Dovecot to the latest available version (1.0.0-rc25). However, despite that, our users still report the same bug: "This bug still persists. In particular, I just (after the new version was applied) clicked on an email from Person X, and Thunderbird displayed an email from Person Y that I had just replied to. Note that the email from Y was not adjacent to the one from X (at least, in the temporal ordering)." I have not been able to reproduce the bug myself. Can anyone think of where we should start debugging? Best regards, Andrey Falko

[Dovecot] 1.0rc26: ssl_verify_client=yes ?
by Leroy van Logchem 08 Mar '07

08 Mar '07

Q1) I can't get ssl_verify_client_cert=yes working. The ssl key and cert are signed using our CA. Also the ssl_ca_file has a CRL appended (no revokes yet). Expected behavior: Stop the SSL (the client doesn't have a cert installed) Current behavior: Mail clients accepts SSL and login succeeds. (both Evolution and Thunderbird). My bad? Please advise. Q2) The next step, if dovecot blocks the client because of the verify_client_cert, how to create certs for OE, Evolution and Thunderbird?

[Dovecot] Config questionsabout various login parms
by Stewart Dean 07 Mar '07

07 Mar '07

I'm currently runing UW-IMAP (compiled vanilla) with procmail and mbox and am making my usual careful crawl (at turtle speed) through figuring out DC config. Some questions: a) I have something like 3-4 root imapd sessions so I presume that the default *login_processes_count* = 3 will be OK. I'm less clear about login_max_processes_count and login_max_connections = 256. A common enough heavy load has something like 275 unique users accessing imap and 600 imapd processes. Suggestions? I'm beginning with no SSL, KISS. b) If I set login_process_per_connection =no, would the number of users accessing imap be the same as the number of imapd sessions? c) login_process_size is confusing/intriguing. If there are 500 processes, the default of 32MB means 16GB (the box has 12GB). OTOH, what about the big players with a 400 MB inbox...will they be able to open their inbox with the default d) login_max_connections ditto...I shouldn't think that an individual user would conceivably have the default of 256, except pathologically....or is this applied to the listening imapd root processes.

[Dovecot] Newbie questions: Load-balanced Dovecot with NFS storage
by Mike Brudenell 07 Mar '07

07 Mar '07

Hi, I experimented with Dovecot a while back and our site is now taking the plunge to switch to it from the UW IMAP server when we rejig the topology of our mail store and IMAP servers. Currently we have a farm of 5 IMAP servers running the UW server. Each has locally attached disk used to store people's mailboxes. Each user is allocated to one of these five servers and can only access their mail via that server. Our aim is to remove this restriction to provide resilience in the event of a server failing. Our thoughts... * We are envisaging having a farm of N (to be determined) servers running Dovecot. These will be closed systems: users do not have shell- access, and can only reach their mail via IMAP. * A single mailstore common to all N servers will be hosted on our NetApp filer and NFS-mounted on each server. Each server would be running Solaris 10. If we use all-new kit it will be x86-based, or we may have to redeploy some of our existing SPARC boxes to the new service. * We will be converting user mailboxes to be in Maildir format. * Our hardware load balancer, which supports persistent sessions, will be used to distribute users between the servers. This could either direct a user to any one of the N servers, or could be set to 'prefer' a given server for a particular user (only failing over to one of the others if their 'usual' server was unavailable). More on this in my questions below. :-) I have been scouring the Dovecot list, archives and Wiki and think I have come up with a set of issues we need to be aware of and things we have to do in order to make this work reliably. Please would you let me know if I have missed or misunderstood anything? Issues To Watch For ------------------- * For timestamp integrity our servers will be synched with NTP to our local time server. * Because sessions could be on different servers memory mapping of index files doesn't work well with NFS, so set mmap_disable=yes in dovecot.conf. * Dovecot relies on the mtime timestamp of mailbox files so the NFS-mounted mailstore needs to be mounted with these options on each server: actimeo=0 (Are there any other mount options we should use too?) * We will be using filesystem quotas on users mailboxes. We understand that Dovecot's index files are best on no-quota filestores so will store these separately. Questions --------- Q1. Would it be better to store the index files on NFS-shared filestore and direct users to any of the IMAP server machines? Or to store the index files on local disk and direct each user to their 'preferred' IMAP server machine? Q2. Does Dovecot (or "something") clean out old index files that haven't been accessed for a while? Eg, when a user has temporarily come through on a different IMAP server to normal. Or do the index files sit there untouched for evermore? Q3. Storing the index files on the NetApp filer would give us the ability to share them between servers and grow their volume as need be, but at the cost of performance. How big do the index files get? Are they typically a few kBytes per message? Per mailbox? Per user? Or more? Q4. We will be using Exim as the MTA, which can deliver direct to Maildir mailboxes. However I understand that Dovecot's "deliver" LDA adds the benefit of updating the index files as each message is delivered. Is this a significant gain? Or is there little difference in actual use? Q5. We have around 20,000 mail accounts and will therefore be seeing lots of concurrent IMAP sessions, usually secure (SSL) ones. I have seen mention that this can give rise to "Too many open files" errors under Solaris. How do we avoid this when we are likely to have several thousand concurrent IMAP sessions per server machine? With many thanks for your time and advice...

[Dovecot] Time moving backwards error
by Emmett Pate 07 Mar '07

07 Mar '07

I'm running dovecot on an OpenBSD 3.7 server and after upgrading to RC25, the daemon started exiting with: Fatal: Time just moved backwards (1173221579 -> 1173221578)! This might cause a lot of problems, so I'll just kill myself now. After upgrading to RC26, I've gotten the error: Error: Time just moved backwards by 1 seconds. I'll sleep now until we're back in present. Occasionally, however, it's followed by: Fatal: Sleep interrupted, byebye. The server is running NTP, but I can't find any reason why it would have to roll the clock back a second so often. Until I get this figured out, I've gone back to RC19. Any ideas? Thanks. -- Emmett "Buddy" Pate Chief Technology Officer William E. Wood and Associates, Realtors epate(a)williamewood.com

[Dovecot] dovecot-ldap.conf - Active directory
by Cristian Salan 07 Mar '07

07 Mar '07

Hello, I have a configuration with dovecot-ldap working with openldap (on FreebSD 5.4 Release). Now I'm trying to do the same thing with an Active Directory (win2k3). I have installed an properly configured SFU. Via nss_ldap-pam_ldap is working fine (FreeBSD 6.2 Release). Because nss_ldap is reported broken with dovecot I'm trying to use dovecot-ldap for both passdb and userdb. My guessed filters/attributes follows: user_filter = (&(objectClass=user)(msSFU30Name=%u)) user_attrs = homeDirectory=msSFU30HomeDirectory, uidNumber=msSFU30UidNumber, gidNumber=msSFU30GidNumber pass_attrs = msSFU30Name,msSFU30Password pass_filter = (&(objectClass=user)(msSFU30Name=%u)) But it doesn't work. Any advice? Cristian Salan

[Dovecot] Question about auth-master, deliver, and SQL maps
by Richard Coleman 07 Mar '07

07 Mar '07

I have been running Postfix/Dovecot with a Postgresql backend for several months, and everything has been running great. Now I want to add server side filtering, so I'm attempting to configure deliver. The SQL maps for Postfix are all keyed upon the recipient email address. The SQL map (user_query) for Dovecot is keyed upon the IMAP login name, which is potentially unrelated to the email address. But when I configure deliver to use auth-master, it doesn't work right, because it is passing the recipient email address as a key to user_query, which is wrong. Somehow, I need auth-master to use a different SQL query from user_query when doing lookups for deliver. In essence, I want deliver to use the same SQL queries where were previously used for the Postfix "virtual" delivery agent. Is there any way to do this? Richard Coleman rcoleman(a)criticalmagic.com

[Dovecot] 1.0.rc25 released
by Timo Sirainen 07 Mar '07

07 Mar '07

http://dovecot.org/releases/dovecot-1.0.rc25.tar.gz http://dovecot.org/releases/dovecot-1.0.rc25.tar.gz.sig Instead of having "Should v1.0 be released already" discussion, how about having "What's still missing from wiki.dovecot.org and how could it be improved" discussion? And what should the wiki exported to doc/ directory in the tarball look like? * If time moves backwards, Dovecot kills itself instead of giving random problems. + Added --with-headers configure option to install .h files. Binary package builders could use this to create some dovecot-dev package to make compiling plugins easier. - PLAIN authentication: Don't crash dovecot-auth with invalid input. - IMAP APPEND: Don't crash if saving fails - IMAP LIST: If prefix.INBOX has children and we're listing under prefix.%, don't drop the prefix. - mbox: Broken X-UID headers still weren't handled correctly. - mail-log plugin: Fixed deleted/undeleted logging.

[Dovecot] 1.0.rc24 released
by Timo Sirainen 07 Mar '07

07 Mar '07

And more fixes. * Dovecot now fails to load plugins that were compiled for different Dovecot version, unless version_ignore=yes is set. This needs to be explicitly set in plugins, so out-of-tree plugins won't have this check by default. - pop3_lock_session=yes could cause deadlocks, and with maildir the uidlist lock could have been overridden after 2 minutes causing problems - PAM wasted CPU by calling a timeout function 1000x too often - Trash plugin was more or less broken with multiple namespaces and with multiple trash mailboxes

[Dovecot] Some question about "auth default", "auth default_with_listener" and others
by Vitalij Satanivskij 06 Mar '07

06 Mar '07

Hello, Trying to set in dovecot.conf more than one auth section found that imap and pop3 auth process use bose of them. Loooks like thay do in round-robin way or maybe another way. Example of config: auth default { mechanisms = plain passdb sql { args = /usr/local/etc/dovecot-mysql.conf } userdb prefetch { } user = root socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = dovecot group = dovecot } } } auth smtp_auth { mechanisms = login plain passdb sql { args = /usr/local/etc/smtp_auth.conf } userdb prefetch { } socket listen { client { user = mailnull # User running Dovecot LDA group = mail # Or alternatively mode 0660 + LDA user in this group path = /var/run/auth-smtp-plain mode = 0660 } } } Main problem - dovecot-mysql.conf and smtp_auth.conf have doferent sql querys inside, and if user try to auth via pop3 service but thru the "auth smtp_auth", than it's failed in any way. Quetion - Is exist any way to limit default doecot auth process to use just "auth default" for authintification ? maybe some options like "services= POP3 IMAP" inside? Or maybe there is anather way to do this ?

[Dovecot] quota warning
by Nicolas Boullis 06 Mar '07

06 Mar '07

Hi, As suggested by Timo, I have tried to implement some warning when the user gets close to his quota limit. The patch is attached. It is configured in the plugin section of the configuration file: quota_warning = 80:0:/usr/local/bin/quota_warning.sh With this one, /usr/local/bin/quota_warning.sh is executed each time a mail brings the total size from below 80% to 80% or above. The second number serves as a limit for the count. The /usr/local/bin/quota_warning.sh script builds the warning message and delivers it with cat << EOF | /usr/lib/dovecot/deliver -c /etc/dovecot-nowarning.conf where /etc/dovecot-nowarning.conf is the same as my normal configuration file, except that it lacks the quota warning option (that is required in a situation where the warning message is large enough to bring over the 80% limit, to avoid a warning loop). Comments are welcome. Cheers, Nicolas Boullis

[Dovecot] user_global_uid - tricky to set
by Alexej Davidov 06 Mar '07

06 Mar '07

Hola! Dovecot should serve virtual mail users. So I've set user_global_uid and user_global_gid in dovecot_ldap.conf to vmail/vmail. Also I've commented auth the user_attrs field. Still Dovecot tries to switch to the uid that is defined in the LDAP entry. It took me some time to figure out, that the only way to prevent this is to set user_attrs = foo=uid,bar=gid or something like this, so Dovecot doesn't have a chance to find the uid/gid. Still it will perform some LDAP lookups. In my oppinion, Dovecot shouldn't try to get the uid/gid from LDAP if the user_attrs field is undefined. I'm using Dovecot 1.0rc24 on Debian sid. Regards, A.

[Dovecot] mbox_min_index_size panics at index-storage.c:368

[Dovecot] Disconnects with proxies / new facts
by Michael Kress 06 Mar '07

06 Mar '07

Hi, I just tried the below with the current version 1.0 RC15 and I still got the Problem: telnet gives me the following output: -----8<-----8<-----8<-----SNIP-----8<-----8<-----8<----- +OK dovecot ready.u-ERR invalid command u s-ERR invalid command s e-ERR invalid command e r-ERR invalid command r -ERR invalid command u-ERR invalid command u s-ERR invalid command s e-ERR invalid command e r-ERR invalid command r _-ERR invalid command _ 1-ERR invalid command 1 -ERR invalid command -----8<-----8<-----8<-----SNIP-----8<-----8<-----8<----- The above output results from the following entry: user user_1[ENTER] So now I know that this is no version issue. Can you tell me something on how I can find the solution for this problem? I don't think its a firewall issue, I disabled my Desktop Firewall. On the server I use shorewall, but of course, port 110 is open and it works disabling AntiVir on the client side. The error also occurs when I disable the Server Firewall as well. The error is reproducible on several PCs (I tried 3 PCs). Have you got any hint? Without solving the problem, I have to switch the pop3 server to another one, because this problem is really a crucial one.The only problem is: I loke dovecot. :) Thanks in advance!

When I configure my dovecot server to do just plain pop3 I can telnet from a windows box without any flaw, but as soon as the client uses some pop3 proxy (for example outlook uses avira antivir Mail-AntiVirus Protection), queries to that server fail. A log line looks like this: pop3-login: Dec 05 22:53:24 Info: Disconnected [::ffff:84.165.54.42] Moreover with the proxy activated, a telnet to port 110 (pop3) is not working properly, the cursor stays right behind "+OK dovecot ready." and as soon as I enter a character, the server rejects this character as an unknown command (Without pressing ENTER). As soon as I turn off the Antivir-Proxy the telnet to port 110 runs flawlessly and I can login. So I'd like to know is there anything I can do with this version or is it worth trying the newest version? Is this a known issue?

[Dovecot] 1.0rc25: double INBOX folder (weird)
by Troy Engel 06 Mar '07

06 Mar '07

Let me start off by saying the initial cause was *not* a Dovecot bug. :) If you have the default namespace "INBOX." (Courier emulation mode from the Wiki) and an actual folder in your ~/Maildir/ with INBOX in the name (~/Maildir/.INBOX.Miami), then Dovecot presents them both to the client as the real Inbox in Thunderbird: Account Inbox (3) Drafts Sent INBOX (3) ...where (3) is me representing a new email account; if you click on either INBOX folder (parent or child) they show the same contents of the single Inbox. It was really confusing until I figured out the Maildir was messed up on the backend. Sometime back in 2004 the Courier-IMAP server let one of my (dovecot) testers create a folder called .INBOX.Miami; until the 1.0rc25 upgrade we never even knew it was there - it has been invisible this whole time. I can only assume that a bug in Courier allowed that folder to be created in the first place, I'm not bothering to track it down. Once I upgraded to 1.0rc25 this morning all the sudden there it was -- obviously not Dovecot's fault for putting it there and it was easy enough to fix by hand, but I thought I'd report it in case it exposed some logic gap in the code. If nothing else Dovecot shouldn't have duplicated the INBOX view to the client, and instead just showed it as a regular folder - yes? -te -- Troy Engel | Systems Engineer Fluid, Inc | http://www.fluid.com

According to http://www.dovecot.org/list/dovecot/2005-June/007569.html support for the Kolab storage format was discussed in 2005. Has this support been added since then? I really don't like Cyrus and would prefer to use Dovecot for my groupware needs.

[Dovecot] Migration
by John s 06 Mar '07

06 Mar '07

Hi, I have a Mailserver setup with Qmail+Vpopmail+courier-imap with 2000 users.The authentication in vpopmail was in plaint text file based.Right now the issue is while opening a user email box with 50-100 mails it is opening fastly.Butfor email-boxes with attachments and increased number of mails it take long time to open the Imap connection. So I would like to change the Imaps to Dovecot.Please suggest if I can migrate from courier-imap to dovecot with vpopmail and qmail without changing the present username and passwords. Thanks in advance for any help. Regards John

[Dovecot] new crashes: is the index/mail cache endian neutral?
by Dan Price 06 Mar '07

06 Mar '07

Part of our migration plan takes our users from one endianness to another (big to little). Will the index and mail cache files survive? I'm seeing some new core dumps as the first test user is migrated, which makes me think... not. What about if we want to build dovecot 64 bit in the future? Will that cause problems too? Stack trace is below the log messages.

[Dovecot] messages lingering in .Trash/new instead of .Trash/cur
by Glenn Leavell 06 Mar '07

06 Mar '07

We're running Dovecot rc15 on Solaris 9, providing IMAP access to e-mail stored in Maildir++. I've noticed that a significant number of message files are currently sitting in the directories ~/Maildir/.Trash/new/. I would have expected that all messages in .Trash would be in the /cur subdirectory (as most are), and I'm not sure how they're landing in /new. If I connect to Dovecot and run something like the following, the messages all *do* immediately end up in .Trash/cur/ : x select blah * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags * permitted. * 4 EXISTS * 0 RECENT * OK [UIDVALIDITY 1150071896] UIDs valid * OK [UIDNEXT 5] Predicted next UID x OK [READ-WRITE] Select completed. x copy 4 "Trash" x OK Copy completed. Most of our users are using Thunderbird, and after looking at various outputs of rawlog, TB seems to be simply issuing uid copy commands to "Trash" like the ones above when a user deletes a message. Do any of you know what IMAP interaction with Dovecot can lead to message files appearing in .Trash/new/ ?

[Dovecot] Driving quota out of a database.
by David Craigon 06 Mar '07

06 Mar '07

Hi there, I'm using postgres as a userdb for dovecot. I'm am trying to get the quota plugin to work. I have a column in my table that returns the quota in KB. I am using the postgres expression "('maildir:storage=' || mailstore_control.mailbox.quota) AS quota" as recommended in the manuals. This expression is NULL to start with, which I take to mean unlimited quota. Trouble is, if I change it to a value, and then change it back to null, I don't seem to go back to unlimited quota. I'm using maildir++ quotas. What gives? :-) David Griffin Information Systems Ltd 20 St Christopher's Way, Pride Park, Derby DE24 8JY www.griffin.com <http://www.griffin.com/> Registered in England and Wales.

[Dovecot] Replacing qmail + vpopmail with: sendmail + dovecot
by Oliver Schulze L. 06 Mar '07

06 Mar '07

Hi, I wonder if it posible to replace qmail + vpopmail with sendmail + dovecot? The idea is like this: - use sendmail + milter API to filter spam/virus and deliver the email to the dovevot MDA (LDA) - dovecot should save the email to the directory as specified in the vpopmail DB - maintain the vpopmail BD (users + passwd) - use dovecot pop3/imap for the clients - use sendmail again to receive the email from the pop3/imap users and deliver the email to the internet as usual. Anyone has done this? It is posible in the paper, in the real world? many thanks Oliver -- Oliver Schulze L. | Get my e-mail after a captcha in: Asuncion - Paraguay | http://tinymailto.com/oliver

[Dovecot] MBOX to MAILDIR conversion
by Marc Perkel 05 Mar '07

05 Mar '07

Thinking about going from mbox to maildir. Started with mbox way back when but thinking about making the conversion. The main reason is that I use rsync for backups and when these huge mailboxes are touched I have to copy the whole thing. With maildir I only copy the files that change. So - my questions is - what's the easiest way to make this happan. I assume there are conversion utilities. I'm using Exim as an MTA. Also - using Ext3 for the file system on a Raid 10 array. Backup server will run Ext3 Raid 1. Is the number of files in one directory going to be a problem? And - any tip/tricks would be appreciated. Things to look out for? Still in planning stage. Thanks in Advance.

[Dovecot] Dovecot ignoring Quotas
by Frank Doege 03 Mar '07

03 Mar '07

Hi, i have installed the dovecot 1.0rc25 and everything is working well. I have connected it to a postgresql database. Now to my little problem: Postfix is delivering into a maildir folder with active maildirquota patches, and this is working well. The problem is only that dovecot is not recognizing the maildirquota file at all. I have configured it as in the documentation with Plugin { Quota=maildir } Anyone any idea ? maybe this is a bug ? Thanks

I have the following /etc/dovecot.conf: mail_location = maildir:/var/spool/mail/%u/ protocols = imap pop3 mail_log_prefix = "%Us(%u):%i:%h " first_valid_uid = 5001 first_valid_gid = 5001 protocol imap { } protocol pop3 { } protocol lda { postmaster_address = postmaster(a)example.com } auth_verbose = yes auth_debug = yes auth default { mechanisms = plain userdb ldap { args = /etc/dovecot-ldap.conf } passdb ldap { args = /etc/dovecot-ldap.conf } user = root } dict { } plugin { } and /etc/dovecot-ldap.conf: hosts = driveable.example.com base = dc=example,dc=com #dn = cn=Directory Manager #dnpass = password auth_bind_userdn = uid=%u, ou=People, dc=example, dc=com uris = ldap://127.0.0.1 user_attrs = mail user_filter = uid=%u user_global_uid = 5001 user_global_gid = 5001 pass_filter = uid=%u The problem is that if we have an entry in LDAP, User Name, with the uid UName, postfix stores the users mail in /var/spool/mail/UName If I log into dovecot using uname (LDAP uid isn't case sensitive) than dovecot tries to look in /var/spool/mail/uname, similarly if I log in with unAME dovecot will look in /var/spool/unAME. However, if instead of using auth_bind_userdn = uid=%u, ou=People, dc=example, dc=com I bind with dn = cn=Directory Manager dnpass = password than it correctly looks in /var/spool/UName regardless of the case used when logging in. It seems like when I log in with auth_bind_userdn %u is being left as the value I logged in with rather than being reloaded from LDAP. I was wondering if I have made some mistake in the configuration files to cause this behaviour or if something else is going on? thanks, Aaron

[Dovecot] automaticly move expunded emails to trash Folder
by Wilfried BARNAVON (Perso) 03 Mar '07

03 Mar '07

Hi I try to migrate from courier to Dovecot. Is there a way to get the same behaviour of Courier-imap with dovecot, about expunged emails ? I though about using the Lazy-Expunge plugin. The problem with this plugin is the following: messages are moved and set to be deleted in the Trash Folder. I would like they weren't set to be deleted. Is there a way to mitigate the behaviour of this plugin, or is there another plugin having this task in charge ? Thanks Wilfried BARNAVON

[Dovecot] Struggle with Postfix/Dovecot-auth and SASL
by Ingo Reimann 03 Mar '07

03 Mar '07

Hi List, I just updated an old sendmail installation to a modern postfix/dovecot system with mysql backend. Everything works fine but SMTP-AUTH fails with some clients. The problem is, that with PLAIN (old) clients send the base64 coded form: USERNAME\0USERNAME\0PASSWORD which, as i understand dovecot interprets as MASTERUSER\0USERNAME\PASSWORD. New clients send \0USERNAME\0PASSWORD which works fine. I don`t like to use masterusers, because then everyone would be able to log in as someone else. When i don`t have a passdb with master=yes in my dovecot.conf, Dovecot complains auth(default): passdb(XXXX(a)YYY.TLD,master): Attempted master login with no master passdbs If i create a passdb with contains everyone, everyone may look into other mailboxes. No good idea. I can`t change the old clients, but for now, i don`t know, what i am doing wrong or how to correct it. No real HowTo for my setup on the net, it seems that everyone uses cyrus-sasl. May anybody help, because i don`t like to switch my setup or use 2 auth daemons. My System: Debian Etch, postfix (2.3.7-3), dovecot (1.0.rc15-2) Best wishes, Ingo Reimann System Manager -------------------------------------------------------------------- ICSmedia GmbH in Münster: Soester Straße 13, 48155 Münster in Dortmund: Mönchenwordt 5, 44137 Dortmund im Internet: http://www.icsmedia.de Telefon: (0251) 60 60-403 Telefax: (0251) 60 60-190 E-Mail: ingo.reimann(a)icsmedia.de -------------------------------------------------------------------- Geschäftsführung: Frank Wulf Sitz der Gesellschaft: Münster Amtsgericht: Münster HRB: 46 97

[Dovecot] Stopping certain users from using IMAP, or POP3, etc.
by David Craigon 02 Mar '07

02 Mar '07

Hi there, I'm building a mail system for an ISP. We want to be able to turn on or off IMAP or POP3 access for certain customers- basically we want to be able to offer a customer POP3 access, unless they pay us some more money, in which case they get IMAP The username and password will remain the same, and are driven out of a postgres database. The best way I've though of doing this so far is by defining separate auth systems for IMAP and POP. Is this the best way? A gold star is available if you can think of a way that if they try and use IMAP but haven't paid for it it rejects them with "Give us all your money..." or some such.

[Dovecot] Doing %var-substitutions in a plugin...
by Nicolas Boullis 02 Mar '07

02 Mar '07

Hi, I'm trying to write a plugin that need to do some %var-substitution. Is there a way to get the var_expand_table used by the process? If not, I guess I could use getenv("USER") (for %u, %n and %d) and getenv("HOME") (for %h); but what for the other ones? Cheers, Nicolas

[Dovecot] Thunderbird : open() failed with index file /home/XYZ/mail/.imap/Trash/dovecot.index: Not a directory
by Charles Bueche 02 Mar '07

02 Mar '07

Hi, almost everything is in the subject. Server : Solaris 9 /SPARC, Dovecot 1.0.rc22 Client : Mac OS X 10.4.8 (8L2127) Kernel-Version: Darwin 8.8.1 Thunderbird is: german Version 1.5.0.9 (20061207) With OS X Mail.app, message deletion works. With Thunderbird, a warning popup appear on the desktop. English translation is about "command failed, internal error occurred". The server log shows : > Mar 1 10:50:35 ZZZ dovecot: [ID 107833 mail.error] IMAP(XYZ): open > () failed with index file /home/XYZ/mail/.imap/Trash/dovecot.index: > Not a directory After checking, I see "Trash plugin was more or less broken with multiple namespaces and with multiple trash mailboxes" in rc24 release notes. Would an update to rc24 fix my user's issue ? Hints welcome, Charles -- Charles Bueche <charles(a)bueche.ch> sand, snow, wave, wind and net -surfer A-Cat SUI 192
