[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

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 ?

To say nothing of having built the whole edifice with the integrity, simplicity and elegance, that these changes are possible. I've long felt that doing programming can give one an awed appreciation for Creation. In principio, in the beginning, it is of the essence to get the first principles right....otherwise, everything that follows is a downhill slide to garbage.

[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] 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

[Dovecot] Sieve Vacation
by Matthieu Vogelweith 06 Mar '07

06 Mar '07

Hi, I'm using Postfix/LDAP with virtual domains and Dovecot 1.0rc15 as LDA with sieve plugin. The sieve plugin works fine except vacation. How can I increase the log level of deliver to see what's the matter ?

[Dovecot] Kolab: Can I use Dovecot instead of Cyrus?
by Matthew Sheffield 06 Mar '07

06 Mar '07

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] rc25: need_space assert, core
by Jeff A. Earickson 06 Mar '07

06 Mar '07

Timo, I see where at least one other person reported this, but here goes. I went from rc24 to rc25 this morning, and I got an assert and core from my own mailbox withing five minutes: Mar 2 06:52:26 karst dovecot: [ID 107833 mail.error] IMAP(jaearick): file mbox-sync-rewrite.c: line 408: assertion failed: (need_space == (uoff_t)-mails[idx].space) Mar 2 06:52:26 karst dovecot: [ID 107833 mail.error] IMAP(jaearick): Raw backtrace: 0x89720 -> 0x46e50 -> 0x47410 -> 0x426d4 -> 0x42d60 -> 0x438b0 -> 0x43b38 -> 0x2a828 -> 0x2ada4 -> 0x231dc -> 0x23368 -> 0x23450 -> 0x8fe14 -> 0x8f638 -> 0x2cd64 -> 0x1dad8 Unfortunately, I switched compilers at rc24 and rc25.

[Dovecot] File descriptor leak in 1.0rc2[45]?
by Victor Duchovni 06 Mar '07

06 Mar '07

I upgraded (NetBSD 2.99 i386) from 1.0rc7 to 1.0rc24 and then tried rc25, and in both cases need to restart Dovecot every day or so (low volume server). It seems to run out of file descriptors. I have now raised the file descriptor limit to 1024, but that is not a long-term solution... ...

[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. I've edited the user's name out and replaced it with foobar, and cleansed out a few sensitive things. -dp dovecot: Mar 01 08:46:49 Info: imap-login: Login: user=<foobar>, method=PLAIN, r

[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

[Dovecot] Using auth_bind_userdn causes uid to be improper case
by Aaron Luchko 03 Mar '07

03 Mar '07

I'm having a problem with dovecot-1.0-1.1.rc15.fc6 + LDAP + auth_bind_userdb. 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.

[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] Deleting when Over Quota
by Daniel Watts 01 Mar '07

01 Mar '07

Hi All, I've read a bit about this but don't really see a full solution anywhere. Has anyone actually got a good fix for this? Telling a user they are over quota then not allowing them to delete anything does seem the height of perversion. =) Question is - is this even a problem for the IMAP server? Or should the MUA be detecting over quota problems and then issuing the right commands to delete messages WITHOUT the copy to Trash? Lastly - even if it is the MUA's responsibility - will Dovecot not still have a problem with indexes? I suspect perhaps not if: A. When using FS Quotas you store the indexes in a non quota partition B. When using other quotas (dirsize / maildir++), Dovecot does not count the index files when counting up the usage. Is B true? Best wishes, Daniel

[Dovecot] Dovecot Plugins - ACL

Hi We run "Dovecot 1.0 Stable" when I try to use the ACL plugin I get the following message: Error: Error in configuration file /etc/dovecot.conf line 391: Unknown setting: mail_plugins Are plugins unsupported in our version, or could this be something else?

[Dovecot] Event on Logout
by Luca Bertoncello 01 Mar '07

01 Mar '07

Hi, @all! Is it possible, with Dovecot, to do something (eg: an SQL-Query) when the User logs out (POP3) or do some action (IMAP)? My problem is to notify a DB when the user logs out or delete E-Mail (in this case, just for IMAP). Thanks for your answer! P.S.: if it is NOT possible, it is my Hit for the next version! :) -- _______________________________ Luca Bertoncello -Programmierung / Mailserver- IMS Internet-Media-Service GmbH Bayrische Str. 18 01069 Dresden Geschäftsführer: Axel C.E.

[Dovecot] How to Prevent IMAP Folders being moved, deleted or renamed
by FreeStyle 01 Mar '07

01 Mar '07

Hello I use exim/dovecot combination for mail delivery and pickup and I'm wondering how I can prevent users from moving, deleting or renaming particular IMAP folders. I use the MailDir mailbox format. The reason for doing this is that I have some special exim filters which deliver mail to specified directories. I don't want users to be able to change these folders because it will mess up the filtering. Also my mail client (Thunderbird) doesn't check the filter folders automatically is there an option in dovecot that lets you send notification to clients when new messages arrive in certain folders. more info: http://kb.mozillazine.org/How_do_I_check_for_new_messages_in_other_folders

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, for testing I have different filesystems on various block devices, which I mount on /mnt/mailcache as needed; however, the indexes and caches are located on /var/cache, hence, they get out of sync easily.

[Dovecot] Force "lower case" Folder Creation?
by Rich, Whidbey Telecom 28 Feb '07

28 Feb '07

We're exploring the use of "plus addressing" in our MTA (Exim), which delivers "user+topic(a)domain.com" to a user's "topic" folder. However, the case-sensitive nature of our ext3 filesystem means that a message destined to "topic" won't deliver to a user's "Topic" folder. For example, if a user creates a "Topic" folder, and gives "user+Topic(a)domain.com" to a web form that lower-cases it, delivery is deferred. Although we're checking to see if Exim can workaround this, is there a way Dovecot (1.0rc24) can force lowercase folder names without a patch? We'd hate to do this but are exploring our options. Thanks! Rich

[Dovecot] 1.0rc_15 - imap-login disappearing
by James Pattinson 28 Feb '07

28 Feb '07

Hi All I am trying to troubleshoot a problem that's been bugging me for several months. About once or twice per week my IMAP server seems to get in a state where no connections are possible (Thunderbird hangs at "Connected to <server>"). Restarting dovecot completely fixes the problem, until it occurs again, hours or days later. I caught the problem today after I rebooted my server, and monitored the running processes while attempting to connect. After each connection attempt, the number of imap-idle processes running decremented until none at all were running. Before the final imap-login process died, I attached an instance of strace to it - results here: http://www.pasteserver.net/286 I am running Dovecot 1.0_rc15 on a Gentoo server. It's a vmware virtual server - mentioning this now just in case, but I'm confident that's not anything to do with it, no other services are having any problems that I am aware of. I am using TLS and Maildir. I don't know enough about how dovecot is supposed to work, so I would appreciate some help in diagnosing this problem! Cheers, James

[Dovecot] dovecot-auth (1.0rc24) on Solaris seems broken.
by Stephen Usher 28 Feb '07

28 Feb '07

I've trying to get dovecot-auth to talk to exim and have been running debugging on both sides. I've added the line: i_info("auth_client_input: client disconnected: %s", strerror(errno)); just after the "case -1" in the first switch statement in: auth-client-connection.c: auth_client_input() and get this in the logs: dovecot: Feb 27 13:35:09 Info: auth(default): auth_client_input: client disconnected: Illegal seek Now, on the exim end if I don't have the i_info() call in the routine the call to fgets() which exim is using never returns. If I put the i_info() call in there it does and gives an error, e.g. 2007-02-27 13:35:09 dovecot_plain authenticator failed for vanguard.earth.ox.ac.uk [163.1.22.82]: 435 Unable to authenticate at present: authentication socket protocol error Now, the istreams code in dovecot seems rather too obscure for me to debug any further. According to the read(2) man page under Solaris 10, the only version of read which can possibly return ESPIPE is pread(). Any ideas what's going on?

[Dovecot] Capability dropping support patch
by David 28 Feb '07

28 Feb '07

Hi, A week ago I submitted an early patch, please ignore it. The patch attached to this email has been tested and seems to work for me. I have also attached instead of inline to solve problems with spaces/tabs. The patch will, on systems that have libcap support, drop capabilities that Dovecot doesn't need. For example there is no need for CAP_SYS_MODULE, which enables module loading or CAP_SYS_PTRACE/CAP_SYS_ADMIN/etc. If libcap isn't installed then nothing will change, this is a compile-time only enhancement that isn't configurable. Personally I did not find that CAP_SYS_CHROOT was needed in order for me to authenticate and access my mailbox, but I haven't configured anything special with chrooting (yet). I added it because I see chroot() is used in src/lib/restrict-access.c. The patch was generated against 1.0-rc24 and tested with clients imp and Thunderbird. My configuration uses a virtual passdb, requires TLS for AUTH and exports auth-master under a different account. All of this appears to work correctly. I'd appreciate any comments, perhaps this will help safeguard the 1000EUR on non-hardened systems :) David

by Garret Huntress 27 Feb '07

27 Feb '07

I had our production systems running on rc23, however we ran into problems when the server was under heavy load. Eventually, the server would begin to freeze all imap connection after authentication (according to the logs). A user would connect, authentication would succeed, and then the connection would sit until timing out. No error logs were produced. Upgrading to rc24 did not resolve the issue, but reverting to rc22 has. -Garret -- Garret W.

[Dovecot] Certs file
by Javier Henderson 27 Feb '07

27 Feb '07

I'm running 1.0rc23 on FreeBSD 6.2-RELEASE, and seeing the following: Starting dovecot. Error: Can't use SSL key file /etc/ssl/private/dovecot.pem: No such file or directory In the config file I have: ssl_cert_file=/usr/local/certs/imapd.pem Looking for dovecot.pem on the config file there's only: % grep dovecot.pem dovecot.conf #ssl_cert_file = /etc/ssl/certs/dovecot.pem #ssl_key_file = /etc/ssl/private/dovecot.pem So the two entries referencing dovecot.pem are commented out. I removed those two lines anyway, just in case, but it didn't make a difference. What am I missing? I'd love to include the output of 'dovecot -n' but... % dovecot -n # /usr/local/etc/dovecot.conf Error: Can't use SSL key file /etc/ssl/private/dovecot.pem: No such file or directory Thanks, -jav

Re: [Dovecot] Solaris problem & exim. Please ignore it.
by Stephen Usher 27 Feb '07

27 Feb '07

Please ignore my previous question.. as it turns out it's a bug/feature of fprintf(3C) and sockets under Solaris. Exim was using fprintf to output the AUTH string and for some unknown reason it was hanging, possibly because the input buffer on the file stream wasn't empty or something. After modifying the Exim's dovecot authentication plug-in to use write(2) instead of fprintf(3C) it miraculously worked!

[Dovecot] lstats on all files in Maildir when opening an e-mail.
by Tan Shao Yi 27 Feb '07

27 Feb '07

Hi, I'm running RC19 on a Solaris 10 SPARC box. It seems that whenever I open an e-mail in any folder via IMAP, dovecot appears to scan every other folder in the Maildir. A truss reveals that it is lstat-ing every e-mail in every directory. I'm sorry I am sending only a fragment of the truss, it's really too long... but is this behaviour expected? Cheers, Tan Shao Yi lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170337156.M209211P18431V025055F0I0000DAF0_0.recess1,S=2596", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170337594.M159985P18549V025055F0I0001891B_0.recess1,S=4111", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170338379.M564254P18933V025055F0I000196A3_0.recess1,S=3630", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170344035.M859029P24106V025055F0I000198E4_0.recess1,S=4254", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170344816.M69242P24829V025055F0I000199CB_0.recess1,S=3810", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170347789.M408186P27905V025055F0I00019A8F_0.recess1,S=3922", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170378895.M589722P25748V025055F0I00019279_0.recess1,S=2782", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170380726.M524353P29456V025055F0I0001AEE1_0.recess1,S=3619", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170381420.M702545P517V025055F0I0001B208_0.recess1,S=3028", 0xFFBFF040) = 0 getdents64(8, 0xFEE72000, 8192) = 0 close(8) = 0 lstat64("/var/qmail/maildirs/AA/AA/test(a)pacific.net.sg/Maildir/.qmail/maildirfolder", 0xFFBFF148) = 0 lstat64("/var/qmail/maildirs/AA/AA/test(a)pacific.net.sg/Maildir/.qmail/cur", 0xFFBFF148) = 0 openat(-3041965, "/var/qmail/maildirs/AA/AA/test(a)pacific.net.sg/Maildir/.qmail/cur", O_RDONLY|O_NDELAY|O_LARGEFILE) = 8 fcntl(8, F_SETFD, 0x00000001) = 0 fstat64(8, 0xFFBFEEE8) = 0 getdents64(8, 0xFEE72000, 8192) = 1088 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/cur/1169092926.M656431P6118V04010002I000023E9_0.recess1,S=4701:2,S", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/cur/1168983168.M76366P8906V04010002I000027AB_0.recess1,S=2345:2,S", 0xFFBFF040) = 0

[Dovecot] pid stamp on log entries?
by bhayden＠umn.edu 26 Feb '07

26 Feb '07

Hi folks. Is there a way to modify the log stamp to include pid as well as time? Preferably for all logging, but at least for imap and pop. I took a look at the mail-login plugin, but that seems to associate operations with uid, still no pid. Am I missing something? Thanks for any info, -Brian U of Minnesota Internet Services

[Dovecot] Quota stored in LDAP
by Venilton Junior 26 Feb '07

26 Feb '07

Hie folks, Does anyone have any experiences using dovecot + per user quota + ldap? I've configured my settings as this example: # quotaStorage must be in the format mentioned above # For example: dirsize:storage=10240 user_attrs = uid,homeDirectory,,,uidNumber,gidNumber,quotaStorage=quota But, Dovecot isn't creating maildirsize file. Any guesses? PS: I've already instaled 1.0rc24 Venilton C. Junior HPS Sercompe Computadores Ltda.

[Dovecot] Bigcrypt password patch
by Philipp Kolmann 26 Feb '07

26 Feb '07

Hi, we are currently in the progress of switching an HPUX mailserver to linux and dovecot. The only issue so far is, that HPUX has bigcrypt for passwords > 8 chars. Bigcrypt uses standard libc crypt for every block of 8 chars. The linux pam modules have a bigcrypt.c file which can be used for dovecot as well to authenticate crypt and bigcrypt passwords. I have used the pam bigcrypt.c code to patch the mycrypt.c dovecot file. Maybe you could add this path (against branch_1_0 cvs). thanks Philipp Kolmann -- If you have problems in Windows: REBOOT If you have problems in Linux: BE ROOT

Hi all, I'm using dovecot 1.0 RC24 compiled form source on a OpenBSD 4.0, I use IMAP service with maildir storage and my mail client is Outlook 2003. If the root of the user maildir stay on the BSD filesystem everything is right. If the root of the maildir is mount on an NFS drive on Microsoft Windows 2003 server, I always have the same error when I try to move mail (under Outlook) form my Pop3 account to my Imap account : dovecot: Feb 24 21:41:13 Error: IMAP(arno): rename(/var/mail/arno/Maildir/tmp/1172353272.P7684Q1.mail.domaine.fr, /var/mail/arno/Maildir/cur/1172353272.P7684Q1.mail.domaine.fr:2,S) failed: Input/output error As you see, the name of the file gets an extra string ":2,S" and that's why the new filename can't be created. what's wrong? thanks --- dovecot.conf ------------------ base_dir: /var/run/dovecot/ log_path: /dev/stderr protocols: imap listen: *:143 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot//login login_executable: /usr/local/libexec/dovecot/imap-login first_valid_gid: 0 mail_location: maildir:~/Maildir mmap_disable: yes lock_method: dotlock auth default: passdb: driver: passwd-file args: /etc/master.passwd userdb: driver: passwd

[Dovecot] Updated SHA256 patch
by Jasper Slits 25 Feb '07

25 Feb '07

Hi, This is the updated version of the SHA256 password hashing patch I submitted earlier to this list. I changed it, based on the suggestions by Andrey Panin (AP). Also some other parts have been changed, summary as follows: [sha2.h] - typedef of context dropped for consistency (AP) - removed ifndef SHA2_TYPES part (AP) - removed sha256() prototype [sha2.c] - added lib.h and safe_memset.h includes - added static const to sha256_h0[8] and sha256_k[64] (AP) - replaced memset with safe_memset - used standard types from stdint.h: (AP) - uint32 -> uint32_t - uint8 -> uint8_t - removed strings.h include - removed PACK64 and UNPACK64 (defined but not used) The updated patch can also be found at http://www.malochia.nl/dovecot/sha256.patch Kind regards, Jasper diff -r -u -N --exclude=Makefile.in --exclude=.deps --exclude=Makefile --exclude=CVS dv_bas/src/auth/password-scheme.c src/auth/password-scheme.c --- dv_bas/src/auth/password-scheme.c 2007-02-25 02:13:29.697424750 +0100 +++ src/auth/password-scheme.c 2007-02-23 14:34:23.940550315 +0100 @@ -10,6 +10,7 @@ #include "mycrypt.h" #include "randgen.h" #include "sha1.h" +#include "sha2.h" #include "str.h" #include "password-scheme.h" @@ -153,6 +154,17 @@ return str_c(str); } +static const char *sha256_generate(const char *plaintext, + const char *user __attr_unused__) +{ + unsigned char digest[SHA256_RESULTLEN]; + string_t *str; + sha256_get_digest(plaintext, strlen(plaintext), digest); + str = t_str_new(MAX_BASE64_ENCODED_SIZE(sizeof(digest)+1)); + base64_encode(digest, sizeof(digest), str); + return str_c(str); +} + static const void * password_decode(const char *password, unsigned int result_len) { @@ -196,6 +208,23 @@ return memcmp(sha1_digest, data, SHA1_RESULTLEN) == 0; } +static bool sha256_verify(const char *plaintext, const char *password, + const char *user) +{ + unsigned char sha256_digest[SHA256_RESULTLEN]; + const char *data; + + sha256_get_digest(plaintext, strlen(plaintext), sha256_digest); + + data = password_decode(password, SHA256_RESULTLEN); + if (data == NULL) { + i_error("sha256_verify(%s): Invalid password encoding", user); + return 0; + } + + return memcmp(sha256_digest, data, SHA256_RESULTLEN) == 0; +} + static const char *ssha_generate(const char *plaintext, const char *user __attr_unused__) { @@ -466,6 +495,7 @@ { "MD5-CRYPT", md5_crypt_verify, md5_crypt_generate }, { "SHA", sha1_verify, sha1_generate }, { "SHA1", sha1_verify, sha1_generate }, + { "SHA256", sha256_verify, sha256_generate }, { "SMD5", smd5_verify, smd5_generate }, { "SSHA", ssha_verify, ssha_generate }, { "PLAIN", plain_verify, plain_generate }, diff -r -u -N --exclude=Makefile.in --exclude=.deps --exclude=Makefile --exclude=CVS dv_bas/src/lib/sha2.c src/lib/sha2.c --- dv_bas/src/lib/sha2.c 1970-01-01 01:00:00.000000000 +0100 +++ src/lib/sha2.c 2007-02-25 01:53:03.876815750 +0100 @@ -0,0 +1,226 @@ +/* + * FIPS 180-2 SHA-224/256/384/512 implementation + * Last update: 02/02/2007 + * Issue date: 04/30/2005 + * + * Copyright (C) 2005, 2007 Olivier Gay <olivier.gay(a)a3.epfl.ch> + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.

[Dovecot] Dovecot on Solaris x86?
by Tim Skirvin 24 Feb '07

24 Feb '07

I'm trying to get dovecot working on Solaris x86. I've got it working just fine on RH Desktop 4; and while I have a built, limping version on solx86, it's not actually usable except from other solx86 systems. Basic details: Version 1.0rc23 OS Solaris x86 (64 bit) CPU Opteron Filesystem NFS (but it's not getting that far) The general problem is apparently SSL-related. I can connect properly from another Solaris x86 machine, using either mutt or straight openssl; but when I try mutt from a Solaris or Linux machine, I get the error "SSL failed: I/O error" and it fails, and when I use openssl from a Linux machine, I get something like this: victor ~> stelnet xxxxxxxx.ks.uiuc.edu 993 + openssl s_client -connect xxxxxxxx.ks.uiuc.edu:993 -verify -debug verify depth is 0 CONNECTED(00000003) depth=0 /C=US/ST=Illinois/L=Urbana/O=UIUC/OU=[...] verify error:num=18:self signed certificate verify return:1 depth=0 /C=US/ST=Illinois/L=Urbana/O=UIUC/OU=[...] verify return:1 24748:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:s23_lib.c:226: Annoyingly, the same command run from a Solaris machine connects, even though mutt doesn't. (I'm using 'mutt -f imaps://xxxx/', which I know works elsewhere; and the Linux mutt is the system default one, so I don't suspect that it is the source of the problem.) The logs have been remarkably un-useful: dovecot: Feb 21 09:41:21 Info: imap-login: Disconnected: rip=[...], lip=[...] TLS handshake The software was built in all cases with: ./configure --prefix=/usr/local/encap/dovecot-1.0rc23.1 I've tried with both Sun's native cc and gcc compilers. I have also tried building on SPARC Solaris with the native cc compiler, to the same (negative) effect. (I used to have v0.99.14 running just fine on this SPARC machine, so this worries me... but I only checked it just now as an after-thought.) Any suggestions? - Tim Skirvin (tskirvin(a)ks.uiuc.edu) -- Theoretical and Computational http://www.ks.uiuc.edu/~tskirvin/ Biophysics, Beckman Institute, UIUC Senior Systems Administrator

[Dovecot] Setting up an email server
by Matt Penfold 24 Feb '07

24 Feb '07

I am sure this is a really stupid question but I could do with some advice. I am setting an old PC as an email/file server using Gentoo Linux. So far I have configured getting emails from a couple of a pop3 accounts I have with ISPs/Mail Service providers using getmail and dovecot. I can access those emails from a variety of clients using IMAP without problem. The next stage I want to implement is to have a central location available to the clients of sent emails as well as received emails. It is this part I am a bit confused about. I know I will need some kind of agent to transfer the email from the client to the appropriate ISP/Mail provider but I am overwhelmed by the choice. Sendmail seems a bit OTT for me needs! And how do I ensure that I can see what emails I have send using IMAP ? Thanks in advance Matt Penfold -- No virus found in this outgoing message. Checked by AVG Free Edition.

[Dovecot] Simple patch
by David 23 Feb '07

23 Feb '07

Inline below is a simple patch that drops the root capabilities that aren't needed (inspired by a similar patch against the mpm_itk project!). Possibly it is a little too restrictive, extras can be added to suidcaps, but on platforms that support capabilities this will prevent things such as kernel module loading. Needed on linux is libcap, available in most distros. Note that this patch doesn't require libcap, or add an option, but if it is installed then it will take advantage of it. I don't have any other platforms to test on. The patch compiles fine but I haven't managed to test it yet. My autoconf experience is zero, so I hope that HAVE_LIBCAP is actually getting defined. Comments appreciated, I'll test it thoroughly later when I get some free time (and, if it works, remove the test message!).

[Dovecot] quota warning
by Nicolas Boullis 23 Feb '07

23 Feb '07

Hi, Is there a way with dovecot to warn users who are close to reach their quota? Although I never used it, I think cyrus supports something like that by droping a warning message into the INBOX when delivering a message that brings the total size over a certain percentage. Would it be feasible to implement something like that with an extra plugin or by changing the quota plugin? Cheers, Nicolas

[Dovecot] Final LDAP issues
by Joseba Torre 23 Feb '07

23 Feb '07

Hi all, I'm in my final steps with my testing server using rc23 in a x86 RHEL4 machine. Everything is working quite well, but still are some LDAP related issues I'd like to clarify: - I'm using auth_bind and auth_bind_userdn. So pass_filter isn't used, and pass_attrs are never searched. Is this true or am I missing something? - Is there a choice for the userdb bind/queries to be done using the user supplied dn -the one used for passdb-? I would like to access some non-public attributes, but I've had no luck until now. If I use the same dovecot-ldap.conf for userdb and passdb, i have a single connection to the LDAP server, but once the auth bind is successful, an anonymous bind occurs. If I use two separate files for userdb and passdb, i have two connections to the LDAP server, the second one being always anonimous. For me, the perfect state would be: - bind using the user supplied dn - if successfull, search for pass_attrs, where some user_attrs may be prefetched - unbind - userdb only binds if some needed attrs haven't been already fetched. If so, there's a choice to use the user supplied dn for the bind/search. Is this possible now? Would it be in the future? Thanks in advance. -- Joseba Torre. CIDIR Bizkaia.

[Dovecot] Strange new mail count

I am having a slight issue with new message count... for some reason, dovecot reports I have some strange number of new messages, even though there are no new messages... If I click on a few of the folders, the new message count seams to correct itself... Any way to solve this?

I added --with-headers configure option now to CVS (not enabled by default). It makes Dovecot install all the useful .h files so that it's possible to compile out-of-tree plugins without having compiled Dovecot sources. I'd hope that binary package builders add a new dovecot-dev package which contains the headers (and $libdir/dovecot- config). I also updated dovecot-sieve so that it compiles against only the header files, except then sievec and sieved binaries aren't compiled (because they require liblib.a).

[Dovecot] 1.0.rc23 released
by Timo Sirainen 22 Feb '07

22 Feb '07

http://dovecot.org/releases/dovecot-1.0.rc23.tar.gz http://dovecot.org/releases/dovecot-1.0.rc23.tar.gz.sig Documentation is probably the only important thing left before v1.0. * deliver doesn't ever exit with Dovecot's internal exit codes anymore. All its internal exit codes are changed to EX_TEMPFAIL. * mbox: X-Delivery-ID header is now dropped when saving mails. * mbox: If pop3_uidl_format=%m, we generate a unique X-Delivery-ID header when saving mails to make sure the UIDL is unique. + PAM: blocking=yes in args uses an alternative way to do PAM checks. Try it if you're having problems with PAM. + userdb passwd: blocking=yes in args makes the userdb lookups be done in auth worker processes. Set it if you're doing remote NSS lookups (eg. nss_ldap problems are fixed by this). + If PAM child process hasn't responded in two minutes, send KILL signal to it (only with blocking=no) - IMAP: APPEND ate all CPU while waiting for more data from the client (broken in rc22) - mbox: Broken X-UID headers assert-crashed sometimes - mbox: When saving a message to an empty mbox file it got an UID which immediately got incremented. - mbox: Fixed some wrong "uid-last unexpectedly lost" errors. - auth cache: In some situations we crashed if passdb had extra_fields. - auth cache: Special extra_fields weren't saved to auth cache. For example allow_nets restrictions were ignored for cached entries. - A lot of initial login processes could cause auth socket errors in log file at startup, if dovecot-auth started slowly. Now the login processes are started only after dovecot-auth has finished initializing itself. - imap/pop3 proxy: Don't crash if the remote server disconnects before we're logged in. - deliver: Don't bother trying to save the mail twice into the default mailbox (eg. if it's over quota). - mmap_disable=yes + non-Linux was really slow with large dovecot.index.cache files - MySQL couldn't be used as a masterdb - Trash plugin was more or less broken - imap/pop3 couldn't load plugins if they chrooted - imap/pop3-login process could crash in some conditions - checkpassword-reply crashed if USER/HOME wasn't set

[Dovecot] Solaris/SSLonly/Lots of Users
by Steven F Siirila 22 Feb '07

22 Feb '07

Anyone running Dovecot on Solaris, requiring only SSL connections, and servicing thousands of simultaneous users? Our past attempts to do so have failed due to dovecot-auth using up all 256 of its file descriptors. I say 256 since we are limited to that by the 32-bit libraries. We are looking at either compiling Dovecot in 64-bit and letting dovecot-auth file descriptors accumulate (not ideal), or providing Timo with access to one of our test servers so he can debug the problem. However, I would like to hear of anyone in the same boat first. Thanks! -- Steven F.

[Dovecot] Dovecot Quota + LDAP
by Venilton Junior 22 Feb '07

22 Feb '07

Hie Folks, I'm having a little problem with quota + ldap. I want to use per user quota settings. So I configured quota on my /etc/dovecot.conf like this site http://wiki.dovecot.org/Quota examples. Here follows my /etc/dovecot.conf: protocols = imap imaps pop3 pop3s ssl_disable = no ssl_cert_file = /usr/share/ssl/certs/cert.pem ssl_key_file = /usr/share/ssl/private/pkey.pem mail_extra_groups = mail valid_chroot_dirs = /var/lib/imap/vmail/domains default_mail_env = maildir:/var/lib/imap/vmail/domains/%d/%n/mail::INDEX=/var/run/dovecot/i ndexes/%n lock_method = dotlock mmap_disable = yes auth_debug = yes auth_debug_passwords = yes first_valid_uid = 202 last_valid_uid = 202 first_valid_gid = 202 last_valid_gid = 202 maildir_copy_with_hardlinks = no login_greeting = Sercomtel Internet ready. disable_plaintext_auth = no protocol imap { mail_plugins = quota imap_quota } protocol lda { postmaster_address = postmaster(a)domain.com mail_plugins = quota } protocol pop3 { pop3_uidl_format = %08Xu%08Xv mail_plugins = quota } auth default_with_listener { mechanisms = plain login userdb ldap { args = /etc/dovecot-ldap.conf } passdb ldap { args = /etc/dovecot-ldap.conf } socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = vmail group = mail } } } plugin { # quota = maildir:/var/lib/imap/vmail/%d/%u/mail:storage=102400 # convert_mail = maildir:/var/lib/imap/vmail/%d/%u/mail #quota = maildir:storage=102400 } And here is my user attributes in my dovecot-ldap.conf: user_attrs = mail,homeDirectory,,,,quotaStorage=quota=dirsize:storage user_filter = (&(objectClass=VirtualMailAccount)(mail=%u)(accountActive=TRUE)(delete=F ALSE)) As you can see above in my dovecot.conf, I made a comment at plugin section to ensure that there's no quota usage for all system. I'd like to have per user quota stored in my ldap base. Here is a value off my quota attribute: quota = 122880 Making tests, the user already have 138 Mb. Does anyone have any idea how to set up quota with ldap and get it working? Tnx for any reply. Best regards, Venilton C. Junior

[Dovecot] Understanding fcntl() error messages
by Dean Manners 22 Feb '07

22 Feb '07

Hey guys, After many trials and tribulations I have now got some fairly stable NFS clients serving dovecot-lda and pop3/imap. Over a 9 hour postal/rabid stress test only saw 5 errors for the 4 servers. Wondering if anyone can shed a bit more light on what they mean exactly. I have tried to find "Resource temporarily unavailable" and "No locks available" in the src to get some understanding - however it appears these messages are from a lower level. With pop3: ------------------ Feb 22 03:36:32 mailget01 dovecot: POP3(test992(a)mailtest06.com): fcntl() failed with file /mnt/mailstore/mailtest06.com/8/test992/dovecot.index.log: Resource temporarily unavailable Feb 22 03:36:32 mailget01 dovecot: POP3(test992(a)mailtest06.com): mail_index_wait_lock_fd() failed with file /mnt/mailstore/mailtest06.com/8/test992/dovecot.index.log: Resource temporarily unavailable Feb 22 04:16:45 mailget01 dovecot: POP3(test445(a)mailtest03.com): fcntl() failed with file /mnt/mailstore/mailtest03.com/4/test445/dovecot.index.log: Resource temporarily unavailable Feb 22 04:16:45 mailget01 dovecot: POP3(test445(a)mailtest03.com): mail_index_wait_lock_fd() failed with file /mnt/mailstore/mailtest03.com/4/test445/dovecot.index.log: Resource temporarily unavailable ------------------ ------------------ Feb 22 13:07:27 mailget01 dovecot: POP3(test999(a)mailtest06.com): fcntl() failed with file /mnt/mailstore/mailtest06.com/8/test999/dovecot.index: Resource temporarily unavailable Feb 22 13:07:27 mailget01 dovecot: POP3(test999(a)mailtest06.com): fcntl() failed with file /mnt/mailstore/mailtest06.com/8/test999/dovecot.index: Resource temporarily unavailable Feb 22 13:07:27 mailget01 dovecot: POP3(test999(a)mailtest06.com): Couldn't open INBOX: Internal error occurred. Refer to server log for more information. [2007-02-22 13:07:27] Feb 22 13:07:27 mailget01 dovecot: POP3(test999(a)mailtest06.com): No INBOX for user top=0/0, retr=0/0, del=0/0, size=0 ------------------ Does this mean that pop3 was waiting for a lock, but timed out ? What are the likely affects of this on a client POPing - session times out and they need to reconnect? The "No INBOX" error is little more odd, the same user had successful login 90 minutes earlier. With deliver: ------------------ Feb 22 01:42:03 mailfilter01 deliver(test680(a)mailtest04.com): fcntl() failed with file /mnt/mailstore/mailtest04.com/10/test680/dovecot.index: No locks available Feb 22 01:42:06 mailfilter01 deliver(test265(a)mailtest03.com): fcntl() failed with file /mnt/mailstore/mailtest03.com/1/test265/dovecot.index: No locks available Feb 22 03:25:42 mailfilter02 deliver(test454(a)mailtest03.com): fcntl() failed with file /mnt/mailstore/mailtest03.com/2/test454/dovecot.index: No locks available Feb 22 03:25:45 mailfilter02 deliver(test397(a)mailtest03.com): fcntl() failed with file /mnt/mailstore/mailtest03.com/7/test397/dovecot.index: No locks available ------------------ I assume this means deliver tried to obtain a lock on the index file (probably many times) but failed. Are the likely affects that the message still gets saved to the maildir but the index doesn't get updated? Regards __________________________________________ Dean Manners

[Dovecot] critical performance problem
by Rene Luria 22 Feb '07

22 Feb '07

I have been using dovecot 1.0alpha4 + deliver/sieve in production for a few accounts (400'000). After testing 1.0.rc22 I decided to upgrade one of the imap servers... And... what a mess ! The server just gets unusable. I don't know why but with new release, it just overloads the system with I/O. It turns that with 1.0.rc22 I get 15Mo/s read on disk average, without any reason. What did really change ? How come a system (with a few thousand accounts) works perfectly and then with 1.0.rc22 gets unusable with a load approaching 300 ? If you have any ideas...

[Dovecot] 1.0.rc23 tomorrow
by Timo Sirainen 22 Feb '07

22 Feb '07

http://dovecot.org/nightly/dovecot-latest.tar.gz Would be nice to get some testing before the actual release. I've now finally gone through all the "TODO" mails in this list and my INBOX and fixed pretty much every problem I know of. There are still some mbox bugs, but I can't really get them fixed unless someone figures out how to reproduce them (http://wiki.dovecot.org/MboxProblems) I think documentation is the last thing that should be done before v1.0. I'm happy enough with the code as it is now, unless some new bugs again appear. The notable changes since rc22: * deliver doesn't ever exit with Dovecot's internal exit codes anymore. All its internal exit codes are changed to EX_TEMPFAIL. + PAM: blocking=yes in args uses an alternative way to do PAM checks. Try it if you're having problems with PAM. + userdb passwd: blocking=yes in args makes the userdb lookups be done in auth worker processes. Set it if you're doing remote NSS lookups (eg. nss_ldap problems are fixed by this). + If PAM child process hasn't responded in two minutes, send KILL signal to it (only with blocking=no) - IMAP: APPEND ate all CPU while waiting for more data from the client (broken in rc22) - mbox: When saving a message to an empty mbox file it got one UID which immediately was incremented. - mbox: Fixed some wrong "uid-last unexpectedly lost" errors. - auth cache: In some situations we crashed if passdb had extra_fields. - auth cache: Special extra_fields weren't saved to auth cache. For example allow_nets restrictions were ignored for cached entries. - A lot of initial login processes could cause auth socket errors in log file at startup, if dovecot-auth started slowly. Now the login processes are started only after dovecot-auth has finished initializing itself. - imap/pop3 proxy: Don't crash if the remote server disconnects before we're logged in. - deliver: Don't bother trying to save the mail twice into the default mailbox (eg. if it's over quota). - mmap_disable=yes + non-Linux was really slow with large dovecot.index.cache files - MySQL couldn't be used as a masterdb - Trash plugin was more or less broken - imap/pop3 couldn't load plugins if they chrooted - imap/pop3-login process could crash in some conditions - checkpassword-reply crashed if USER/HOME wasn't set

[Dovecot] --log-error and the mysterious "not starting" problem
by Marshal Newrock 22 Feb '07

22 Feb '07

I've finally upgraded to 1.0.rc21. If I run "dovecot --log-error", then dovecot fails to start. The following appears in the log: Feb 5 10:54:00 taurus1 dovecot: Dovecot v1.0.rc21 starting up Feb 5 10:54:00 taurus1 dovecot: This is Dovecot's error log Without --log-error, it will start up fine from command-line. Dovecot still fails to start, as near as I can tell, in the specific condition that it is being started from a non-interactive shell and there is a mail_plugin set in "protocol imap". mail plugins set for pop or lda do not cause this problem. The failure to start appears in only two instances that I can see: on boot, or by a monitoring script if dovecot crashes, or, since I haven't seen dovecot die, when I manually stop it to see if the monitoring program will restart it. With the above problem, if the init script has --log-error when I try to make the monitoring program restart dovecot, then nothing still gets logged. -- Marshal Newrock, Ideal Solution LLC http://www.idealso.com

[Dovecot] False "new mail" warning from Thunderbird, using RC23
by Stephen Warren 21 Feb '07

21 Feb '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I am continually getting false "New Mail" warning from Thunderbird. I'm running Thunderbird 1.5.0.9 on Windows, and it's talking to two different Dovecot 1.0.RC23 servers (one home server, one work server). This was happening in older Dovecot versions too, so it's not new in RC23. Very often, Thunderbird will pop up the "new mail" notification window, and put a "new mail" icon in the Windows icon bar. However, when I view the main Thunderbird window, there will be no folders with new mail. Simply changing the currently selected folder in Thunderbird will clear the tray icon. Sometimes the notification window will say something small like "7 new messages", but right now, it's showing huge numbers like "587 new messages", which could be the total message count in one of my folders... Sometimes restarting Thunderbird will stop this happening for a short while. Is this a Thunderbird bug? Am I the only one seeing this? Does it have to do with having two separate IMAP servers configured? Perhaps it's because Thunderbird is configured to cache 5 connections to the server (although I think that's the default?) Should I delete all my accounts in Thunderbird, delete the (Thunderbird) cache files etc. on disk, and re-create it all? I do notice that whenever Thunderbird starts, it displays a whole load of folders that don't exist (e.g. got renamed/deleted) and/or multiple copies (e.g. Sent, Sent-1, Sent-2), which disappear very quickly. Is this related? -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFF2+eJhk3bo0lNTrURAh9uAKCWYrcNByF+wE2e1FPvL6x8N48/uACgtwxR 07fYmnaG9P/JCBOkKscCZIA= =XWXG -----END PGP SIGNATURE-----

[Dovecot] auth_user setting?
by Joseba Torre 21 Feb '07

21 Feb '07

Hi all, I've installed rc23 in a new testing machine, and i've had some permission problems related to dovecot-master.conf. As I have my master passwords in that file, I don't want it to be world readable. dovecot -n shows that auth_user is nobody, so setting the permissions to nobody.whatever 640 solves the problem. Anyway, I've tried to change the auth_user setting with no effect. Is it configurable? Aaaaaaaaaagur. -- Joseba Torre. CIDIR Bizkaia.

[Dovecot] Possible Bug in quota-fs.c
by Martin Konopka 20 Feb '07

20 Feb '07

Hi, I'm using filesystem quotas with dovecot 1.0rc22 on my Linux 2.4.27 box. The quota limit gets correctly reported in kilobytes to the client but the amount of used space is reported in megabytes. In quota-fs.c I noticed that only the currently used space is divided by 1024: Line 241: *value_r = dqblk.dqb_curblocks / 1024; *limit_r = dqblk.dqb_bsoftlimit; After removing /1024 everything works fine. regards, Martin

[Dovecot] Convert plugin

convert_mail = mbox:%h/mail Convert plugin. If set, specifies the source storage path which is converted to destination storage (mail_location) when the user logs in. The existing mail directory is renamed to <dir>-converted. I'm not entirely clear on what this does. If someone can clarify for me, I'll update the Wiki. I'm hoping it'll allow me to convert from mbox to Maildir-- otherwise I'm looking at a weekend of downtime when that project comes due... -- Jay Chandler Network Administrator, Chapman University 714.628.7249 / chandler(a)chapman.edu Today's Excuse: high pressure system failure

[Dovecot] Reading mail for Virtual and Real LDAP Users
by Aaron Luchko 20 Feb '07

20 Feb '07

I'm trying to setup a system with ldap+postfix+dovecot. Everyone who gets an email is stored in LDAP, some of these users also have a local unix account, regardless I want all users to be dealt with as virtual users. All the mail is stored by postfix in /var/spool/mail in Maildir format with permissions 600 vmail:vmail. Everything works fine when dovecot tries to read the mail of a completely virtual user, the problem is when dovecot tries to read mail for a user who has an account on the machine, dovecot finds the user's local account, then it tries to read the mail as that user. Even if first_valid_{u,g}id is low enough to allow login the user still doesn't have sufficient permissions to read the mail. I can't figure out why this is happening and was hoping someone could help me out. thanks, Aaron /etc/dovecot-ldap.conf: hosts = server.example.com base = dc=example,dc=com dn = cn=Directory Manager dnpass = password 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 /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 passdb pam { } userdb passwd { } userdb ldap { args = /etc/dovecot-ldap.conf } passdb ldap { args = /etc/dovecot-ldap.conf } user = root } dict { } plugin { }

by Cassidy B. Larson 20 Feb '07

20 Feb '07

Started implementing the MasterUser changes to my config files so I can finally offer SPA for pop3/imap. Things are working fine with the MasterUser (horray!), however one of my guys started using SPA with Outlook Express and started getting another users mailbox. Turns out to be related to NTLM. His Outlook express is configured for the username of 'johnsmith'. However, you'll see the NTLM took the username from his XP machine login, it appears, which is just "John". However, what is really weird, is the "failed" on the "client out" line, but then the proxy went ahead and proxied to the storage server. Here's some output from debuggage: dovecot: Feb 19 16:15:56 Info: auth(mail.infowest.com): client in: AUTH 1 NTLM service=POP3 lip=204.17.177.60 rip=209.33.215.142 resp= dovecot: Feb 19 16:15:56 Info: auth(mail.infowest.com): client out: CONT 1 dovecot: Feb 19 16:15:56 Info: auth-worker(mail.infowest.com): sql(John, 209.33.215.142): query: SELECT a.clearpasswd AS password, v.storeIP AS host, CONCAT(IF('John' LIKE '%(a)%.%',CONCAT(LCASE('John'),''),CONCAT(LCASE('John'),'@',p.host)),'*masteruser') AS destuser, 'Y' AS nologin, 'Y' AS nodelay, 'Y' AS proxy, 'masterpass' AS pass FROM iwmailsystem.virtmailbox AS v INNER JOIN iwmailsystem.popserversAS p ON ( p.storeIP = '204.17.177.60') INNER JOIN authenticate.users AS a ON (a.userID= IF('John' LIKE '%(a)%.%',CONCAT(LCASE('John'),''),CONCAT(LCASE('John'),'@', p.host))) WHERE v.userID = IF('John' LIKE '%(a)%.%',CONCAT(LCASE('John'),''),CONCAT(LCASE('John'),'@',p.host)) AND v.client_active=1; dovecot: Feb 19 16:15:56 Info: auth(mail.infowest.com): password(John, 209.33.215.142): Credentials: 8447128CC04AD05D1CD15F0C2F17F136 dovecot: Feb 19 16:15:57 Info: auth(mail.infowest.com): client out: FAIL 1 user=John host=204.17.177.76 destuser= john(a)host.com*masteruser nologin proxy pass=masterpass dovecot: Feb 19 16:15:57 Info: pop3-login: proxy(John): started proxying to 204.17.177.76:110: user=<John>, method=NTLM, rip=209.33.215.142, lip= 204.17.177.60 Questions: 1) So is it possible to use OE for SPA authentication without it sending the "XP username", but the actual account username OE is configured for ? 2) Why, when it "FAIL"ed did it still proxy? This seems bad :) Thanks, Cassidy

[Dovecot] relocating indexes.
by Rob Shepherd 20 Feb '07

20 Feb '07

Dear Dovecot users, I'd like to relocate indexes from NFS to local storage. I plan to replace... default_mail_env = maildir:~/.maildir with mail_location = maildir:~/.maildir:INDEX=/usr/local/var/dovecot/index/%u However, to minimise disruption, by avoiding dovecot rebuilding indexes for many user's large and numerous folders, I'd like to copy the existing indexes to the new location. Here is a list of _my_ indexes (in and under ~/.maildir) ./.Drafts/dovecot-uidlist ./.Drafts/dovecot.index ./.Drafts/dovecot.index.cache ./.Drafts/dovecot.index.log ./.OpenLDAP/dovecot-keywords ./.OpenLDAP/dovecot-uidlist ./.OpenLDAP/dovecot.index ./.OpenLDAP/dovecot.index.cache ./.OpenLDAP/dovecot.index.log ./.OpenLDAP/dovecot.index.log.2 ./.Sent/dovecot-keywords ./.Sent/dovecot-uidlist ./.Sent/dovecot.index ./.Sent/dovecot.index.cache ./.Sent/dovecot.index.log ./.Trash/dovecot-keywords ./.Trash/dovecot-uidlist ./.Trash/dovecot.index ./.Trash/dovecot.index.cache ./.Trash/dovecot.index.log ./.mailscanner/dovecot-keywords ./.mailscanner/dovecot-uidlist ./.mailscanner/dovecot.index ./.mailscanner/dovecot.index.cache ./.mailscanner/dovecot.index.log ./.mailscanner/dovecot.index.log.2 ./.nagios/dovecot-keywords ./.nagios/dovecot-uidlist ./.nagios/dovecot.index ./.nagios/dovecot.index.cache ./.nagios/dovecot.index.log ./.samba/dovecot-keywords ./.samba/dovecot-uidlist ./.samba/dovecot.index ./.samba/dovecot.index.cache ./.samba/dovecot.index.log ./.samba/dovecot.index.log.2 ./.sw-announce/dovecot.index ./.sw-announce/dovecot.index.cache ./.sw-announce/dovecot.index.log ./dovecot-keywords ./dovecot-uidlist ./dovecot.index ./dovecot.index.cache ./dovecot.index.log ./dovecot.index.log.2 Would I be correct in copying these to /usr/local/var/dovecot/index/rob/ (_my_ new index loc) whilst preserving the structure of the folders etc. Thanks Rob -- Rob

[Dovecot] startup script under FreeBSD 6.2 / dovecot-1.0rc22
by Alexis Susset 20 Feb '07

20 Feb '07

Hi all, I recently installed Dovecot rc22 from the FreeBSD ports and I have some problem with the dovecot startup: - If I start dovecot manually, it works fine, it starts and I get messages in /var/log/maillog - If I reboot the machine, that's where the problem appears, dovecot doesn't seem to start and I get nothing, no errors in /var/log/maillog Any idea if this is a known problem and how to fix it ? Thanks in advance, Regards, -- Alexis

[Dovecot] Run fetchmail after login?
by Brett B. 20 Feb '07

20 Feb '07

Hello all, I was wondering if it is possible to run fetchmail after a user logs into dovecot? So far I have tried to make a small script that contains the command for fetchmail. Then I told the dovecot mail_executable to look at that script. However this ends up leaving the server hanging and does not seem to work. Thanks

[Dovecot] Dovecot losing .mailboxlist files
by Lauri Jesmin 20 Feb '07

20 Feb '07

Hello! I am running a site that has two servers, 10 000 users in both, Solaris 9 and home directories with mbox mailboxes shared with NFS. Indexes are kept separately in both server, on local disks, both servers are serving imap (from NFS mboxes). We are trying to convert from uw-imap to dovecot. Servers are currently running on their limits and now i have mysterious problems with .mailboxlist file: i patched dovecot to use .mailboxlist file instead of .subscriptions, but sometimes the .mailboxlist file disappears on some users. Instead there are appearing .nfsXXXXXX files, where XXXXXX is combination of numbers and capital letters. Also some users have problems with subscribing to folders, others do not have this problem. It seems to be that users who do not have .mailboxlist have also problems with subscribing to folders. Dovecot is version 1.0rc22. I have not discovered error messages in logs. -- Lauri Jesmin <lauri.jesmin(a)ut.ee> Tartu Ülikool

[Dovecot] Weird Issues with latest nightly (pre-rc23)
by Cassidy B. Larson 20 Feb '07

20 Feb '07

Just updated one of my proxy boxes to the latest nightly (20070217), restarted the dovecot process and got a bit of errors showing up for each pop3/imap connection. Feb 19 11:14:00 marbella dovecot: pop3-login: Login: user=<user1(a)host.com>, method=PLAIN, rip=209.33.217.218, lip=204.17.177.60 Feb 19 11:14:00 marbella dovecot: POP3(user1(a)host.com): Set pop3_uidl_format in config file Feb 19 11:14:00 marbella dovecot: child 33684 (pop3) returned error 89 Feb 19 11:14:04 marbella dovecot: imap-login: Login: user=<user2(a)host.com>, method=PLAIN, rip=204.17.177.50, lip=204.17.177.60 Feb 19 11:14:04 marbella dovecot: IMAP(user2(a)host.com): mbox: Can't create root mail directory /dev/null/mail: Not a directory Feb 19 11:14:04 marbella dovecot: IMAP(user2(a)host.com): MAIL environment missing and autodetection failed (home /dev/null) Feb 19 11:14:04 marbella dovecot: child 33753 (imap) returned error 89 On the pop3 errors above. Why should I have a pop3_uidl_format in the config file for the proxy? This was working fine on rc19. I do have a pop3_uidl_format on my storage boxes. Same with the imap section. It should just proxy over (and is on rc19), the proxy shouldnt have to know about the mail directory. Am I the only one seeing this? Or have I missed a config change that is required? thanks, Cassidy

[Dovecot] Dovecot authentication problem
by Marion Keith 20 Feb '07

20 Feb '07

Hi all, New SUSE 10.2 install, Sendmail, dovecot 1.0.rc14-7 SUSE rpm. Was using PAM for authentication. Worked like a champ since Feb 7th. No changes to system. Yesterday authentication failed. I can't even authenticate locally with "telnet localhost" options to test pop3 or imap. It appears that my pam authentication has somehow gotten changed. Can anyone direct me to some PAM debugging help? Thanks, Marion

[Dovecot] LDAP auth load? (looking for advice)
by Troy Engel 19 Feb '07

19 Feb '07

One of the changes my beta testers are testing is switching from NIS to LDAP for login/auth/homedir lookups; all is working perfectly, Dovecot + PAM/nss_ldap is A-OK. No issues here, we've been using LDAP lookups on other servers for years. I'm wondering about load, specifically if when I switch the entire company over, will the new authentication load stress my LDAP server to the point of breaking. A) Does anyone here have some numbers or experience in this switch that could lend some real-world advice? We're talking maybe... 50 people with large (numerically, not gig-age) mailboxes, and ThunderBird seems to open 4-5 connections per client based on the logs. B) Would anyone advise that I run a slapd slave directly on the main Dovecot server to alleviate load? Is this overkill and I shouldn't worry about it? Mainly what has me concerned is that on the Dovecot machine, I'm getting a number of entries in the messages that look like: dovecot-auth: nss_ldap: reconnecting to LDAP server... dovecot-auth: nss_ldap: reconnected to LDAP server after 1 attempt(s) No failures ever, it all just works. But still this tickles my brain that maybe it'll need more robustness come production time. Thanks for your feedback, -te -- Troy Engel | Systems Engineer Fluid Inc. | http://www.fluid.com

[Dovecot] repeat downloads of message headers in 1.0rc19
by Brian G. Peterson 19 Feb '07

19 Feb '07

I upgraded one server to 1.0rc19 (from rc15) over the weekend, and have since received several reports of dovecot erroneously retrieving older messages as new mail. I've seen this myself intermittently on KMail, and users have reported it on Thunderbird, Squirrelmail, and Outlook. I see some things in the archives that suggest that this was a problem in older 1.0 release candidates, but hadn't experienced the problem myself until just now. Has anyone else seen this problem?

[Dovecot] wrong dovecot GID while upgrading
by Zbigniew Szalbot 18 Feb '07

18 Feb '07

Hello, I tried to upgrade dovecot from 1.0.rc7 to rc22 but I got this error at the end of the upgrade process: Dovecot has reserved the groupname 'dovecot' and gid '143': ERROR: groupname 'dovecot' already in use by gid '1003' Please resolve these issues and try again: Either remove the conflicting group or if you wish to continue using a legacy gr oup override DOVECOT_GID. *** Error code 1 Stop in /usr/ports/mail/dovecot. So I went to /usr/ports/mail/dovecot and edited the Makefile to change the GID into: DOVECOT_UID?= 1003 DOVECOT_GID?= 1003 SCRIPT_ENV+= DOVECOT_UID=${DOVECOT_UID} \ DOVECOT_GID=${DOVECOT_GID} I saved the makefile and ran portupgrade again but I got stopped by exactly the same error. I'd appreciate suggestions how to resolve this. Thank you! -- Zbigniew Szalbot

[Dovecot] Reproducible duplicate messages bug with Mail.app+Dovecot
by Andrew Moran 18 Feb '07

18 Feb '07

Hey guys, I am not sure if this is a Mail.app bug or a dovecot bug. I can reproduce it 100% of the time using dovecot and Mail.app. I cannot reproduce it with other imap clients, which at first made me think it was Mail.app, but then I tried Mail.app with other imap servers and couldn't reproduce it either, so it's definitely the combination of the two. So I thought I'd try you guys first before submitting a bug to Apple. The problem: If I move multiple messages (set "A") from one imap folder to another, then delete those messages, and then move another set into that same folder (set "B"), then all the messages in set B show up as duplicates until I relaunch Mail.app. My configuration: Server: Dovecot 1.0rc22 using Maildir on FreeBSD 6.1 Client: Mail.app 2.1 on OS X 10.4.8 Steps to reproduce: (these steps involve trashing messages, so it's best to test this on email you are going to toss anyway) 1) Create a new imap folder (let's say "bar") 2) Drag more than one message (let's say 3 or 4) from existing imap folder "foo" to new folder "bar". 3) Click on new folder "bar" and see messages in there. 4) Select messages and delete them (Delete key). Messages are gone as expected. 5) Go back to original folder "foo" and drag a few more messages into new folder "bar" 6) Click on bar. 7) You will notice that all the second set of messages show up twice. Relaunching Mail.app at this point makes the problem disappear. I'm guessing this has something to do with the deleted messages from Set A being purged until the close of imap connection. Any help narrowing this down would be appreciated. Thank you, --Andy

[Dovecot] Problem moving emails with attachments or HTML links
by J. Wren Hunt 18 Feb '07

18 Feb '07

I recently switched from UW-IMAP to Dovecot (1.0.rc15 on Ubuntu) and am experiencing a weird problem that I haven't been able to figure out yet: If I try to move a message from one IMAP folder to another, all works fine if the message is plain text. However, *sometimes* the message will not be transferred if it contains either an attachment and/or an HTML link (operation times-out). Not all the time, but just enough to be annoying. I've looked through the logs and for settings in the .conf file and can't find anything obvious that I've overlooked. Can anyone help me with any parameters that might be causing this type of problem? Thanks so much! Wren Hunt Cambridge, MA

Hi all, Trying to migrate my actual mailserver postfix Cyrus-IMAP with virtual users to dovecot. done some tests and seems to work quite well except for; I would like to integrate my virtual configuration to share SQL information throw various daemons, like postfix, amavis and so on. By default, Dovecot sets the database users table to "users" but I would like to change it to "mailboxes". this is because I don't want to change all my configiuration files already setup, only for dovecot. is this possible? best regards, xtura Fedora Core 6 Dovecot 1.0 rc22

[Dovecot] [Fwd: wrong dovecot GID while upgrading]
by Zbigniew Szalbot 17 Feb '07

Sorry to have bothered - just read the updating file...! I should have let the upgrading process remove the dovecot user... Warm regards, ZS ---------------------------- Original Message ---------------------------- Subject: wrong dovecot GID while upgrading From: "Zbigniew Szalbot" <zbyszek(a)szalbot.homedns.org> Date: Sat, February 17, 2007 21:10 To: dovecot(a)dovecot.org -------------------------------------------------------------------------- Hello, I tried to upgrade dovecot from 1.0.rc7 to rc22 but I got this error at the end of the upgrade process: Dovecot has reserved the groupname 'dovecot' and gid '143': ERROR: groupname 'dovecot' already in use by gid '1003' Please resolve these issues and try again: Either remove the conflicting group or if you wish to continue using a legacy gr oup override DOVECOT_GID. *** Error code 1 Stop in /usr/ports/mail/dovecot. So I went to /usr/ports/mail/dovecot and edited the Makefile to change the GID into: DOVECOT_UID?= 1003 DOVECOT_GID?= 1003 SCRIPT_ENV+= DOVECOT_UID=${DOVECOT_UID} \ DOVECOT_GID=${DOVECOT_GID} I saved the makefile and ran portupgrade again but I got stopped by exactly the same error. I'd appreciate suggestions how to resolve this. Thank you! -- Zbigniew Szalbot -- Zbigniew Szalbot

[Dovecot] Dovecot "open files" (again?)
by falz 17 Feb '07

17 Feb '07

I'm a new dovecot user, just began using it last week. I switched from courier because my research showed that Dovecot did indexes, and allows me to store them anywhere I chose. I did this, and it fixed some severe disk IO issues that my server had. (25k horde only webmail install using imap proxy). I'm using quotas, and by default had it set to 'dirsize'. my postfix is already creating 'maildirsize' files, so I opted to change dovecot to use this instead. However, when I do, I run into the "too many open files" issue that's been reported many times on the list. I've seen a lot of mention of too many open files, but I haven't seen it related to the quota type used. It's possible that simply my using 'dirsize' as the quota type slows things down enough to not have the issue? I don't really know. Anyhow. I doubled my max open files in FreeBSD's /boot/loader.conf to: kern.maxfiles="24656", but to no avail. When I have it set to maildirsize, the open files on the system grows uncontrollably. Under normal use, it's somewhere below 5k: sysctl -a | grep openfiles kern.openfiles: 4415 I looked into the patch mentioned here: - http://www.dovecot.org/list/dovecot/2006-November/017536.html - http://dovecot.org/list/dovecot-cvs/2006-November/006776.html Those patches already appear to be in rc15, which I'm already running (Via FreeBSD's ports). I also applied the patch mentioned here awhile back: - http://www.dovecot.org/list/dovecot/2005-June/007647.html and rebuilt, but it didn't help out either. There are also freebsd specific notes on forcing a limit on dovecot itsself using login.conf, but that wouldnt really fix anything, it would just cause dovecot to not interfere with other running daemons. - http://www.mail-archive.com/ports@openbsd.org/msg08646.html Any thoughts? TSS, you mention a few times in these notes that you're unable to reproduce this. Perhaps try with the maildir as quota? More details about my setup: - FreeBSD 4.8 (yea, I know) - Imapproxy (http://www.imapproxy.org/) - Postfix to create maildir++ maildirsize folders - MySQL backend The work of this is spread out between several servers, dovecot is running on the server that's the final SMTP delivery location, and has local disks with the maildirs. --falz

Hello, Have been to dovecot website but could not find information on what I need to check before I upgrade from the current 1.0rc7 which I am using on a FreeBSD 6.2 system. Will the old conf (virtual users, no ssl) file work with upgraded dovecot? Many thanks! -- Zbigniew Szalbot

[Dovecot] Problem/workaround with X-Keywords and Apple's Mail.app
by Joey Coleman 17 Feb '07

17 Feb '07

Hello, I've just switched from UW-IMAP to Dovecot, and for the most part, things are good. However, I encountered the problem with the X-Keywords header not being written back into individual messages in an mbox file (originally described in [1], and Timo gave a clue as to maybe why in [2]). What was happening for me is that Apple's Mail.app would flag a message as spam, which happily sets a couple keywords in the message, but those weren't being written back (at least, I didn't see them in the file on the server). The "DO NOT DELETE..." message had a perfectly fine X-IMAP header, and up until I switched things were working great. The user visible symptom of this happened every time new spam arrived in my Junk folder [3] --- the new spam would arrive, be flagged as spam by Mail.app, and the earlier pieces of mail would promptly be unflagged! Anyway, Timo's clue in [2] prompted me to turn off both mbox_lazy_writes and mbox_dirty_syncs (the latter just on the off- chance... it's a low-volume server, so I can deal with the inefficiency). Lo and behold, Mail.app started acting sane again *and* the X-Keywords header appeared immediately. Oddly, during all of this, the Status and X-UID keywords would appear in the messages just fine; no clue as to why those and not X- Keywords. Version details are: - Dovecot 1.0rc13 [4] - FreeBSD 5.3-RELEASE - Apple Mail.app 2.1 (752/752.2) cheers, --joey [1] http://dovecot.org/list/dovecot/2006-March/011872.html [2] http://dovecot.org/list/dovecot/2006-June/014126.html [3] And it felt really strange while troubleshooting this as I found myself *hoping* for another piece of spam to arrive. Bleh. [4] Yes, two versions behind current, but in my defense, I did check the announcements and they didn't seem to mention the problem.

Hello! I see the internal message from pine with the following subject (mbox format, dovecot 1.0rc22): DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA As far as I know this message should be filtered.

[Dovecot] again... cross compiling
by Martin Höfling 17 Feb '07

> Create a cache file with the right values, or call configure with those > values set in the environment. OK, i ran configure with -C one time without cross compiler env set, to obtain the variables another time with -C to use the config.cache . I could not find anything related to the check whether size_t is signed. I found a variable which i set that way: ignored_signed_size=${ignore_signed_size=1} What's wrong with that? Cheers Martin P.S.: Is there a way to obtain all variables in an easy way, or to obtain the variable that has to be set by hand? -- Frag' nicht - Du könntest eine Antwort erhalten.

Since deliberate choice is required to go in and set the maillist option, this is no different than if I configure my MUA to set the reply-to header on messages I send to the list. So the way it has been implemented for this list is not a problem at all. If people feel the need to reply to me off list, I feel that should be a deliberate choice on their part. -- Kenny Dail <kend(a)amigo.net>

[Dovecot] filtering out LIST cruft?
by Dan Price 17 Feb '07

17 Feb '07

In planning our migration, I've noticed that lots of users have bits of lint in their ~/mail and/or ~/Mail. For example-- for an mbox called "blah" we may see: blah blah.msf (from Thunderbird) .blah.summary (from... I'm not sure, dtmail maybe) .blah_SIMS_index0003 (from our old IMAP server). When the user goes to "subscribe" they are often overloaded with too many items to choose from-- because all of these files are selectable in the UI-- LIST happily returns them. Is there a way to get dovecot to skip over these, by regex? Could it optionally "taste" files to see if they look like mboxes? I looked at the wiki and the source but didn't find anything. In the absence of this feature, I wonder how other sites have handled this? Obviously I can do some cleanup during migration, but I find that those pesky msf files like to come back. -dp -- Daniel Price - Solaris Kernel Engineering - dp(a)eng.sun.com - blogs.sun.com/dp

[Dovecot] severe performance problem (mail cache related?)
by Dan Price 17 Feb '07

17 Feb '07

Hi all, we're having a bad day with email :) I have a user who was complaining of poor performance today when opening mailboxes. Total time to open the box was about 1 minute. Upon truss'ing the imap process during an open, I saw the trace quoted below at the end of the email. As you can see, for each "FETCH" line of response, we were seeing dovecot do a ton of work-- mmaping anon, lots of munmaps(), etc. -- mmap() and munmap() are not free. The stack trace of at least one of the munmaps is captured below, as well-- deep inside of the mail caching code. Then, I moved aside the user's .imap directory, assuming that forcing dovecot to rebuild its indices and caches could help-- and sure enough the user reported that mailbox open times had dropped to 18 seconds. I truss'd that open, briefly, and it was just a ton of preads at high speed. So I don't know why this user was fine for a week, then suddenly hit this. This is a grave concern if I'm going to roll this out from 15 test users to 250 production users. Thanks for your help.

by Robert Schetterer 16 Feb '07

16 Feb '07

Hi @ll, with dovecot latest following http://wiki.dovecot.org/DovecotLDAPostfixAdminMySQL i have defined plugin { quota = maildir acl = vfile:/etc/dovecot/acls trash = /etc/dovecot/dovecot-trash.conf } Example dovecot-trash.conf file 1 Spam 2 Trash 3 Sent from wiki The Trash plugin. When saving a message would make user go over quota, this plugin automatically deletes the oldest mails from configured mailboxes until the message can be saved within quota limits. this dont work at my setup where quota is coming out of sql is there any trick to solve this? or did i missunderstand something -- Mit freundlichen Gruessen Best Regards Robert Schetterer https://www.schetterer.org Munich/Bavaria/Germany

Re: [Dovecot] repeat downloads of message headers in 1.0rc19
by Jim Garrison 16 Feb '07

16 Feb '07

I reported this against rc7 and rc8, and still see it occasionally. (I'm running the rc8 that comes with Fedora 5). It is always associated with this message in dovecot.log: dovecot: Oct 23 19:26:17 Error: POP3(user(a)domain.tld): mbox sync: UID inserted in the middle of mailbox /var/mail/vhosts/domain.tld/user (12 > 4, seq=2, idx_msgs=5) Once this happens, dovecot will refuse to clear out the mbox file when the user retrieves email via POP. Each time the user logs in to retrieve mail s/he gets everything in the mbox, which continues to grow. The only fix I've been able to find is to manually delete the mbox file. I'm using postfix as the MTA.

[Dovecot] Proxy with MasterUser + Authentication issues
by Cassidy B. Larson 16 Feb '07

16 Feb '07

Per Timo's direction, I decided to give the MasterUser a try in connecting my proxy to my destination server. This might allow for the use of 'secure password' for my clients that like to check that box by default. A couple of problems I'm running into running RC15: #1: My Proxy's SQL password_query line: password_query = SELECT a.clearpasswd AS password, v.storeIP AS host, CONCAT(v.userID,'*someuser') AS destuser, 'Y' AS nologin, 'Y' AS nodelay, 'Y' AS proxy, 'somepass' AS pass FROM iwmailsystem.virtmailbox AS v NATURAL JOIN authenticate.users AS a WHERE v.userID = '%u' and v.imap_active = 1 I'm wanting to authenticate the user on the proxy before I send it off via the MasterUser to the destination server. However, I show this in the logs: Info: auth(default): client in: AUTH 1 PLAIN service=IMAP lip= x.y.z.a rip=a.b.c.d resp=AGJ1dGNoQGluZm93ZXN0LmNvbQBzZWNyZXQ= Info: auth-worker(default): sql(user(a)host.com,a.b.c.d): query: SELECT a.clearpass wd AS password, v.storeIP AS host, CONCAT(v.userID,'*someuser') AS destuser, 'Y' AS nologin, 'Y' AS nodelay, 'Y' AS p roxy, 'somepass' AS pass FROM iwmailsystem.virtmailbox AS v NATURAL JOIN authenticate.users AS a WHERE v.userID = 'user(a)host.com' and v.imap_active = 1 Error: auth(default): file auth-request.c: line 207 (auth_request_save_cache): assertion failed: (extra_fields == NULL || (strstr(extra_fields, "\tpass=") == NULL && strncmp(extra_fields, "pass=", 5) != 0)) Error: child 54122 (auth) killed with signal 6 The Wiki showed I should return a 'pass' column. However, that's choking the query up in auth-request.c. Could it be the "\tpass" from auth-request.c? If I change user(a)host.com's password to 'someass' and remove the 'pass' column from the password_query, it authenticates, and proxy's over just fine. Am I doing something wrong? I want to authenticate the user locally on the proxy and pass off the 'master password' to the proxy, but using 'pass' doesnt work. 'password' column does. Doesnt help me though for my situation :) Problem #2: I'm wanting to put the masteruser/pass in the database for quick retrieval and updating. So I setup dovecot.conf as: passdb sql { # Path for SQL configuration file, see doc/dovecot-sql.conf for example args = /usr/local/etc/dovecot-sql.conf master=yes #pass=yes } passdb passwd { } and dovecot-sql.conf with: password_query = SELECT '%u' AS user, 'master-password' AS password Trying to connect locally with a "telnet localhost 143" via: 1 login user(a)host.com*someuser "somepass" Give me this in the detail log file: Info: auth(default): client in: AUTH 1 PLAIN service=IMAP lip= a.b.c.d rip=w.x.y.z resp=AGJ1dGNoQGluZm93ZXN0LmNvbSphZG1pbkBpbmZvd2VzdC5jb20AbWFzdGVyLXBhc3N3b3Jk Error: auth-worker(default): BUG: PASSV had invalid passdb ID Warning: Killed with signal 15 I am able to successfully authenticate with the master user/pass if I store it in a passdb file. However, I'd prefer to have it in the database for obvious reasons. Any help to the above would be appreciated. thanks, Cassidy

[Dovecot] Dovecot proxy question (hostname instead of ip)
by Wouter de Jong 16 Feb '07

16 Feb '07

Hello, We are planning to use the Proxy feature of Dovecot, but fail to implement it currently the way we would like to. Reason is that proxy insists to have an IP-address as host : Feb 15 15:43:24 proxy-test.widexs.nl dovecot: pop3-login: proxy(username): mspool01-test.widexs.nl is not a valid IP When I changed the query to force the IP-address of the above server, it works. Would it be possible to make this work, but more important ... Are there any reasons NOT to make this work ? :)) Kind regards, Wouter. -- WideXS http://www.widexs.nl Wouter de Jong System-Administrator Tel +31 (0)23 5698070 Fax +31 (0)23 5698099 Bijlmermeerstraat 62, 2131 HG HOOFDDORP, NL

[Dovecot] domain truncated
by Nemanja Miletic 16 Feb '07

16 Feb '07

Hi all, I have a problem with domain information being truncated from username during ldap search, so it can not be used in mail_location. This happens when user part of the username %n is used in pass_filter in passdb ldap search. When I use %u all username information remains and mailbox can be located. Here is my configuration. In dovecot.conf I have two locations one for system and one for virtual users: ... mail_location = maildir:/var/spool/mail/%n mail_location = maildir:/var/spool/mail/vdom/%d/%n ... Also two configurations for passdb: ... passdb ldap { args = /etc/dovecot-ldap.conf } passdb ldap { args = /etc/dovecot-ldap-virt.conf } ... Here info is searched in ldap: /etc/dovecot-ldap-virt.conf ... base = dc=%d,ou=Virtual Domains,dc=eunet,dc=yu pass_filter = (&(objectClass=posixAccount)(uid=%n)) ... And the line in log file stating that maildir can not be located: mkdir(/var/spool/mail/vdom//cone/cur) failed: Permission denied Is this a bug or I am doing something wrong. Thank You, Nemanja

I'm not sure if this is related or not, but we set mmap_disable=yes last week and since then have seen what appears to be an occasional infinite loops.

[Dovecot] Wiki to doc/ in tarball
by Timo Sirainen 16 Feb '07

16 Feb '07

So I finally started building a script that does it. Anyone interested in helping with it so that it produces readable output? First step is getting raw wiki pages. I'll do this directly by getting them from the filesystem. You can get them from here: http://dovecot.org/tmp/wikipages.tar.gz Next there's http://dovecot.org/tmp/wiki2txt.pl which is my horrible Perl script that kind of works now to produce almost readable text files. Its current output is in http://dovecot.org/tmp/wikitxt.tar.gz One thing I'm wondering about is how to make the directory layout work. For example there is "UserDatabase" and "UserDatabase/Static" pages. Currently I'm placing the latter into "_UserDatabase/Static" but I don't think that's the best solution. I was thinking about adding some "include" and "exclude" lists. If a page is in excluce list it's skipped. If it's in neither list it prints a warning but still includes it. So this makes it easy to find out the new pages and figure out if they should be included in the documentation.

[Dovecot] Son't have IMAPS

Hi, I've installed dovecot and i'm pretty sure it has SSL support built in. But i don't have IMAPS. I get all sort of errors. Thunderbird tells: "The connection was refused". If i disable imaps, imap works just fine. If i enable it, none of them work. The certificates in /etc/ssl/certs and /etc/ssl/private are the same ? Any help would be appreciated.

[Dovecot] Is it 1.0 yet?
by Marc Perkel 15 Feb '07

15 Feb '07

OK - my last main bug was fixed a few releases ago. I know that there's no end to getting things right but there comes a point when you need to call it done. No one trusts a 1.0 to be perfect but Dovecot is already better that most 2.0 versions of other software. I vote (as if my vote counted) to call it done, declare victory, and move on to 1.01, 1.02 etc. No one is going to trus it till it gets to 1.02 so I say lets bless it and move on.

[Dovecot] 1.0.rc22 released
by Timo Sirainen 15 Feb '07

15 Feb '07

http://dovecot.org/releases/dovecot-1.0.rc22.tar.gz http://dovecot.org/releases/dovecot-1.0.rc22.tar.gz.sig Found another bad bug in rc19 changes. Wonder why my imaptest catched the bug only in CVS HEAD but not in branch_1_0 even though both had it. Anyway, now the imaptest runs nicely for both, and I'm again optimistic that the bug count is low enough for v1.0 to be released soon :) BTW. My previous benchmarks which showed how mmap_disable=yes and fsync_disable=yes give huge performance benefits are pretty XFS-specific. I did some quick tests with ext3 and the differences were quite small with it. I'll probably do another proper run of tests later. + pop3: Commit the transaction even if client didn't QUIT so cached data gets saved. - Fixed another indexing bug in rc19 and later which caused transactions to be skipped in some situations, causing all kinds of problems. - mail_log_max_lines_per_sec was a bit broken and caused crashes with dovecot -a - BSD filesystem quota was counted wrong. Patch by Manuel Bouyer - LIST: If namespace has a prefix and inbox=no, don't list prefix.inbox if it happens to exist when listing for %.

[Dovecot] selective logging
by T. Horsnell 15 Feb '07

15 Feb '07

>From the wiki: log_path = Use this logfile instead of syslog(). /dev/stderr can be used if you want to use stderr for logging (ONLY /dev/stderr - otherwise it is closed). (I dont understand the above references to the use of stderr) info_log_path = For informational messages, use this logfile instead of the default (What exactly is an informational message, and what is the default?) Can I selectively suppress logging like: Feb 5 11:52:15 ls1 imap(iamelel): File isn't in mbox format: /gfg0/iamelel//claudia/ligplot/NQ10/ligplot.bonds Or do I have to turn off logging entirely?

[Dovecot] maildir and the separator for subfolder
by David Bonnafous 15 Feb '07

15 Feb '07

hi, I use dovecot 1.0rc15 with one maildir namespace. I'd like to be able to use '.' in folders and subfolders name. So, I setup the default namespace with separator =':' But, when I create some folders and then subfolders with thunderbird the filename one the server are named with some '.' no ':'... It seems that dovecot always interprets '.' as a separator for folders. Is-it a bug ? yours, -- David Bonnafous Institut de Mathématiques Université Paul Sabatier Toulouse - France

[Dovecot] deliver LDA permission problem
by Dick Middleton 15 Feb '07

15 Feb '07

Hello, I'm trying to get deliver LDA working with postfix in a virtual domain configuration. I'm using dovecot v1.0.rc10. My setup is pretty much exactly as in the wiki (only the path to deliver and auth-master socket are different). I'm having a little problem with permissions and this occurred which I think is undesirable: syslog: Feb 8 13:09:35 deliver(<email-addr>): setgid(5002) failed: Operation not permitted Feb 8 13:09:36 deliver(<email-addr>): setgid(5001) failed: Operation not permitted mail.log: Feb 8 13:09:36 Devil postfix/pipe[9622]: 5AD5C103C: to=<<email-addr>>, orig_to=<<email-addr>>, relay=dovecot, delay=0.05, delays=0.01/0/0/0.04, dsn=5.3.0, status=bounced (Command died with status 89: \"/usr/libexec/dovecot/deliver\") When deliver fails because it can't connect to auth-master socket it returns an undeliverable status which causes postfix to defer delivery. I think it should do the same here. The real question is how I give deliver the permission to do the setgid? Is it enough to just add user vmail to each of the virtual user groups in /etc/group. Does deliver setuid to virtual user as well? Dick

[Dovecot] dict quota not being updated for all users when receiving a multi-recipient message
by Justin McAleer 15 Feb '07

15 Feb '07

I've set up a mysql quota dictionary using the proxy setup as described in the wiki (using Dovecot lda). When I send a single message to multiple users, only the first recipient is getting their usage updated. This behavior occurs if I manually send to more than one user via the To: line, or via aliases set up in postfix. I do have dovecot_destination_recipient_limit set to 1. I don't even have a guess as to what might be going on here, since each instance of the lda is a separate process. But, let me know if anybody has any ideas or requests for more info.

[Dovecot] sieve plugin
by pod 15 Feb '07

15 Feb '07

I'm currently looking at dovecot for a large-scale deployment. The requirements will almost certainly mean we would use the dovecot lda with the sieve plugin. The current method of distribution causes (binary distro) packaging to be slightly awkward IMHO. The dovecot-sieve code needs to be told where an in-tree build of dovecot lives. The fact that it _must_ be an in-tree build I was considering as a bug; the dovecot-sieve build wants to access both '.a' and '.h' files from the dovecot build but in an out-of-tree build these are in different places. My first thoughts were to simply move the dovecot-sieve code into the dovecot tree (I imagine under src/plugins/cmusieve or similar) and rework the autoconf setup as appropriate. This sidesteps the problem for this case but does not help other 'third party' dovecot plugins. If however a simple plugin build environment were to exist as part of a dovecot install then plugins could be distributed and built as independent packages. I quite understand that this additionally burdens dovecot development with 'stable API' concerns which may not be considered worth the effort. Timo: have you thought about any of the above and if so which direction have your thoughts taken you? I can justify spending a small amount of time to develop this into real code but it would be a waste to fight against or duplicate existing effort that has gone into this area. All comments welcome.

[Dovecot] leaking file descriptors? imap-login: inotify_init() failed
by Dale Bewley 15 Feb '07

15 Feb '07

Even though the system is configured to allow a large number of open files, and tools such as lsof tell me dovecot is within that limit; I am seeing errors like this pretty frequently. dovecot: imap-login: inotify_init() failed: Too many open files I'm running Fedora Core 5 (2.6.18-1.2257.fc5 SMP x86_64) with dovecot-1.0-1.rc15 built from the FC6 SRPM, but I was seeing the same thing with 1.0-0.beta8.3.fc5 (one of the reasons for the jump to the FC6 ver). # system default limit is very high, and we aren't approaching it [root@mail 2496]# cat /proc/sys/fs/file-max 738223 [root@mail fs]# cat file-nr 8704 0 738223 # the limit per user is 1024 [root@mail 2496]# su -c 'ulimit -n' dlbewley 1024 # But dovecot doesn't appear to be above that. # it looks like the master process is well below that [root@mail 2496]# lsof -p `cat /var/run/dovecot/master.pid` | wc -l 280 # but overall, this user has way more than that [root@mail fs]# lsof -nu dovecot |wc -l 3145 So, I raised the limit for dovecot to 5000 soft and 10000 hard to see if it would make a difference. Even after a reboot, the next day the errors returned. Today login_process_per_connection is set to 'no' rather than the default to see if it makes a difference. So far today, no errors.

[Dovecot] POP3-Proxy error
by Christian Froemmel 15 Feb '07

15 Feb '07

Hi, as mentioned in another thread I discovered a crash in the pop3-proxy. It occurs when the remote-pop3-server just drops the connection (in my case courier was hitting the MAXPERIP-Limit). I don't have a corefile yet, but will try to get one. Here the message from the dovecot.log: dovecot: Feb 02 09:30:00 Error: pop3-login: file pop3-proxy.c: line 20 (proxy_input): assertion failed: (!client->destroyed) dovecot: Feb 02 09:30:00 Error: pop3-login: Raw backtrace: pop3-login [0x8052fe0] -> pop3-login [0x8052ab4] -> pop3-login(vfprintf+0x2324) [0x804c6fc] -> pop3-login(vfprintf+0x2c9a) [0x804d072] -> pop3-login(vfprintf+0x1086) [0x804b45e] -> pop3-login(vfprintf+0x29d0) [0x804cda8] -> pop3-login [0x8056346] -> pop3-login [0x8055849] -> pop3-login(vfprintf+0x39d6) [0x804ddae] -> /lib/i686/libc.so.6(__libc_start_main+0xc7) [0x4015bd17] -> pop3-login(SSL_write+0x49) [0x804a931] dovecot: Feb 02 09:30:00 Error: child 5985 (login) killed with signal 6 It seems that the unexpected shutdown of the connection confuses dovecot. When I increased the MAXPERIP-limit in courier the crashes went away. regards, Christian -- SYSTEM CONCEPT GmbH

[Dovecot] master user
by Tom Bombadil 15 Feb '07

15 Feb '07

Greetings all... We are thinking about using the master DB, so a few admins can impersonate an ordinary user. So, we want to define one master for a set of users. And this administrator cannot be master of the other users? Can this be done somehow? Reading the docs, it seems that if a user is defined as master, it can login as everyone. Thanks for any hint.

[Dovecot] Startup errors
by Steven F Siirila 15 Feb '07

I just finished setting up a test Dovecot server (1.0-rc15, Solaris 10) and noticed upon start of Dovecot (after rebooting the server) that the imap-login and pop3-login processes spew errors as follows, which I can only assume is due to the fact that dovecot-auth has not fully initialized yet... it seems to me that these login processes are getting started too early, or should at least be waiting for dovecot-auth to get started.

[Dovecot] Q on configuring shared mboxes
by Mikhail Teterin 15 Feb '07

15 Feb '07

Hello! I have the following three types of mailboxes on my server: 1) Regular user mail /var/mail/<user> in mbox format 2) Suspected spam in /var/tmp/spamprobe in mbox format 3) Archived mailing list in /home/mks/mksarch in mbox format I want the 1) to be only accessible to the respective <user>, obviously (POP3 and/or IMAP4). I wanted the 2) to be accessible to all users -- and I want them to be able to move stuff out of it into their own mboxes (IMAP4 is enough). I want the 3) to be accessible _read only_ to anyone, who enters the correct username/password (preferably -- without creating a special Unix account). (IMAP4 or POP3) So far, I have only been able to achieve 1). Could someone, please, help me configure dovecot for the 2) and the 3)? Thanks! -mi

[Dovecot] lda sieve broken after upgrade

upgraded to rc19. using maildirs. solaris 9/cc. removed all modules from pop/imap/lda subdirs and first upgraded dovecot to rc19 and then used dovecot-sieve-1.0.1 sources to build against the dovecot source directory ( everything now builds nicely on Solaris, thank you Timo ). added "cmusieve" to the list of plugins used by lda. ail_plugins = cmusieve now getting this: deliver(lenny): Error: dlopen(/usr/local/dovecot/lib/dovecot/lda//lib90_cmusieve_plugin.so) failed: ld.so.1: deliver: fatal: relocation error: file /usr/local/dovecot/lib/dovecot/lda//lib90_cmusieve_plugin.so: symbol deliver_mail: referenced symbol not found anyone ? on the same machine, mbox based dovecot rc19 with dovecot ( sieve ) lda, works and upgraded without any issues, although the prior version must have been different, since the cmusieve statement was already present.

[Dovecot] auto-detection of user mailbox type - followup
by John Harper 15 Feb '07

15 Feb '07

In http://www.dovecot.org/list/dovecot/2006-December/018253.html Timo Sirainen wrote > > You can still change NAMESPACE_* environments. I don't remember how > exactly now, but you can do eg. "set > /tmp/sets" in the script, see > what it has set and modify them in the script. in response to my query regarding setting the mail_location in namespaces from a mail_executable script. The purpose of this is to be able to select on a per-user basis whether they're using Maildir or mbox format (I don't want to convert 12000 users all at once, and some users have no need or desire to change formats - they still use mail/elm etc) and also have the UW-IMAP compatibility namespaces to take care of all the clients currently configured with imap server directory = mail/. This all works, with one small bug left. For reference, here's the gist: In the dovecot.conf file place the usual namespace directives following the Namespaces wiki: namespace private { separator = / prefix = inbox = yes } #for UW backwards compatibility: namespace private { separator = / prefix = mail/ hidden = yes } namespace private { separator = / prefix = ~/mail/ hidden = yes } namespace private { separator = / prefix = ~%u/mail/ hidden = yes } define the mail_executable under protocol imap: mail_executable = /usr/local/dovecot/lbin/imap.sh and write the imap.sh script: ------start imap.sh--------------------------------------------------- #!/bin/sh # determine if user is in mbox or Maildir mode # Maildir takes precedence and is identified by the existence of # both a .procmailrc recipe and the Maildir directory. # Without a .procmailrc file, there's no recipe to force delivery in # Maildir format, so any existing Maildir is spurious # The .procmailrc should contain DEFAULT=Maildir/ # Set the absolute path to this script as the mail_executable for # the imap protocol in dovecot.conf. # It appears that this script is run as the user in their home dir if [ -f .procmailrc -a -d Maildir ]; then MAIL='maildir:~/Maildir'; export MAIL else MAIL='mbox:~/mail:INBOX=~/.mail'; export MAIL fi # each namespace defined in the conf file needs to have the mail # location defined which is set in environment vars # NAMESPACE_1 etc NAMESPACE_1=$MAIL; export NAMESPACE_1 NAMESPACE_2=$MAIL; export NAMESPACE_2 NAMESPACE_3=$MAIL; export NAMESPACE_3 NAMESPACE_4=$MAIL; export NAMESPACE_4 #debugging to see what else we can play with #set >> /tmp/d exec /usr/local/dovecot/libexec/dovecot/imap ------end imap.sh----------------------------------------------------- However, it appears that the root dir '~/mail' string is used at some point before the tilde-expansion takes place. I see a literal ~ directory in the users home, with an empty mail directory inside. After that it picks up the proper location and works correctly. I tried a %h and got a literal %h directory. So for now I made a simple workaround by using the absolute path to the home directory: # use home variable (depends on this script running in users home) # During startup it seems like ~/mail is interpreted as a string and # a spurious ~ folder is created, before the ~ is expanded home=`/bin/pwd` if [ -f .procmailrc -a -d Maildir ]; then MAIL="maildir:$home/Maildir"; export MAIL else MAIL="mbox:$home/mail:INBOX=$home/.mail"; export MAIL fi Thanks, John Harper ------------------------------------------------- Senior Systems Administrator Information and Instructional Technology Services University of Toronto Scarborough harper(a)utsc.utoronto.ca

[Dovecot] dovecot and libnss-ldap
by Nicolas Boullis 15 Feb '07

15 Feb '07

Hi, I've been using dovecot 0.99.14 for a few years, with libpam-ldap and libnss-ldap, and never experienced any problem with those. I expect to soon switch to dovecot 1.0rc15 (or whatever gets available in Debian Etch, hopefuly dovecot 1.0), but I've seen some warnings against dovecot+libnss-ldap... Is the problem with libnss-ldap a recent problem (I mean it was not a problem with older dovecot such as my 0.99.14)? Is it still a problem even with 1.0rc22? Is there any hope to have it fixed before 1.0? Note that while most of the users I have to deal with are in my LDAP directory, a few ones are not and are in /etc/passwd. Hence, "userdb ldap" is probably not an option for me (and I'm quite happy with configuring all my servers with PAM and NSS). Cheers, Nicolas

[Dovecot] DoveCot compression to save HDD space
by Host Expert 15 Feb '07

15 Feb '07

Hello, I am wondering if there are any possibilities to save HDD space used by emails by compressing content (not just attachements). It would be many 1000s email boxes and probably each using lot of space so would be easier if we can just compress emails somehow. Thanks, Cristian

[Dovecot] Last login fields
by Dean Manners 15 Feb '07

15 Feb '07

Hey guys, Wondering if anyone has tried to do this before - a last login timestamp field. Using mysql for auth, I figured it would be easy enough to add a timestamp field and then tack an UPDATE statement on the end of the password_query. But of course, dovecot sees this as only one statement to pass to MySQL - of which MySQL barfs at.. Any ideas on how to achieve this ? Regards __________________________________________ Dean Manners

[Dovecot] Dovecot not responding
by Andrew Hoag 15 Feb '07

15 Feb '07

Hi all, I'm pulling my hair out on this problem and wanted to throw it out there to see if anyone else had run across it. I recently restarted my server. There were some network config issues that caused the interfaces not to come back up, but my colo company got those resolved. However, after restart, my IMAPS server has stopped responding to outside requests. I can successfully access IMAP from localhost, as well as via SSH tunnelling, so I know it is working. I've tried all sorts of "listen=" configurations, and checked lsof & tcpdump to rule out other problems, but it just seems as though dovecot isn't responding. TCPDUMP (notice the TCP SYN but no response): /var/log 89# tcpdump -vvs 192 port 993 tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 192 bytes 17:37:54.101518 IP (tos 0x0, ttl 112, id 56543, offset 0, flags [DF], length: 48) c-24-9-151-115.hsd1.co.comcast.net.3132 > mail.server.com.imaps: S [tcp sum ok] 1828791628:1828791628(0) win 16384 <mss 1460,nop,nop,sackOK> 17:37:58.282840 IP (tos 0x0, ttl 59, id 54721, offset 0, flags [DF], length: 60) dsl001-148-165.sfo1.dsl.speakeasy.net.39250 > mail.server.com.imaps: S [tcp sum ok] 3827175783:3827175783(0) win 5840 <mss 1460,sackOK,timestamp 1555809446 0,nop,wscale 2> 17:38:00.130267 IP (tos 0x0, ttl 112, id 56548, offset 0, flags [DF], length: 48) c-24-9-151-115.hsd1.co.comcast.net.3132 > mail.server.com.imaps: S [tcp sum ok] 1828791628:1828791628(0) win 16384 <mss 1460,nop,nop,sackOK> 17:38:01.283013 IP (tos 0x0, ttl 59, id 54722, offset 0, flags [DF], length: 60) dsl001-148-165.sfo1.dsl.speakeasy.net.39250 > mail.server.com.imaps: S [tcp sum ok] 3827175783:3827175783(0) win 5840 <mss 1460,sackOK,timestamp 1555810196 0,nop,wscale 2> LSOF: /var/log 91# lsof -i | grep imap sshd 4475 andrew 11u IPv4 39601 TCP localhost:34661->localhost:imaps (ESTABLISHED) dovecot 6540 root 5u IPv4 38988 TCP *:imaps (LISTEN) imap-logi 6599 dovecot 9u IPv4 39602 TCP localhost:imaps->localhost:34661 (ESTABLISHED) imap-logi 6629 dovecot 1u IPv4 38988 TCP *:imaps (LISTEN) imap-logi 6630 dovecot 1u IPv4 38988 TCP *:imaps (LISTEN) NETSTAT: /var/log 92# netstat -an | grep 993 tcp 0 0 0.0.0.0:993 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:993 127.0.0.1:34661 ESTABLISHED tcp 0 0 127.0.0.1:34661 127.0.0.1:993 ESTABLISHED STRACE: 17:00:33.225030 gettimeofday({1171501233, 225048}, {480, 0}) = 0 17:00:33.225072 gettimeofday({1171501233, 225090}, NULL) = 0 17:00:33.225113 poll([{fd=7, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=10, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=3, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=1, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 4, 0) = 0 17:00:33.225163 gettimeofday({1171501233, 225182}, {480, 0}) = 0 17:00:33.225212 gettimeofday({1171501233, 225230}, NULL) = 0 17:00:33.225260 poll([{fd=7, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=10, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=3, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=1, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 4, 999) = 0 17:00:34.225145 gettimeofday({1171501234, 225179}, {480, 0}) = 0 17:00:34.225204 gettimeofday({1171501234, 225222}, NULL) = 0 17:00:34.225246 poll([{fd=7, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=10, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=3, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=1, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 4, 0) = 0 17:00:34.225297 gettimeofday({1171501234, 225315}, {480, 0}) = 0 Has anyone seen this behavior? What's the obvious thing I'm missing here? My host has some weird VLAN thing installed by the colo company so I have IP aliases, but given I'm not even seeing a response to the SYN, it doesn't seem to be a routing issue, and I can connect to my local interface on port 993 (NOT localhost) without problems. Suggestions much appreciated, I'm stuck. I'm sure this is something obvious and simple, but I'm looking past it right now.

[Dovecot] OT: looking for plugin developer
by Tom Bombadil 15 Feb '07

15 Feb '07

Greetings all, We are looking for a developer to write a plugin that copies the message to a specific hidden folder called "spam_copy" when a message inside a folder called "spam" is viewed for the first time. And when we move the message from the "spam" folder to any other folder, and if the message hasn't been seen, we should send a copy of it to "spam_copy" hidden folder, in addition to the move. If anybody is up for it, please send me a private message, so we can arrange all the details, payment, etc... Thanks in advance.
