[Dovecot] One final issue
by Tom Ray [Lists] 22 Jul '04

22 Jul '04

Timo- Thanks for all the help. After I changed the permissions to the virtual user I setup I had a few small issues but was able to work through them. Now IMAP is running great. But my new question is, do I need to do anything to get it to work with POP? My server refuses to respond on 110 and I'm wondering if there is something I need to do? I was under the impression that Dovecot can handle both POP/IMAP requests. TIA Tom

[Dovecot] Authentification with PostgreSQL

Hi all, I found Dag Wieers' Fedora Core 2 rpm on http://dag.wieers.com/packages/dovecot/ and installed it. Now dovecot-auth isn't complaining anymore about an unknown userdb type but I can't get authentication working. /etc/dovecot.conf (...) # Authentication process name. auth = default # plain digest-md5 anonymous auth_mechanisms = plain auth_userdb = pgsql /etc/dovecot-pgsql.conf auth_userdb = pgsql /etc/dovecot-pgsql.conf auth_user = root auth_verbose = yes (...) /etc/dovecot-pgsql.conf connect = host=localhost dbname=xams-dovecot user=dovecot password=hallo default_pass_scheme = PLAIN password_query = SELECT password FROM users WHERE username = '%u' user_query = SELECT home, uid, gid FROM users WHERE username = '%u' If I try to login over imap (no ssl) with Mozilla Mail, authentification will always fail (username: felix(a)schwarz-online.org, password: "hallo"). /var/log/syslog Jul 22 15:48:47 steinchen postgres[2057]: [30-1] DEBUG: forked new backend, pid=2198 socket=10 Jul 22 15:48:47 steinchen postgres[2198]: [31-1] DEBUG: Passwortpaket erhalten Jul 22 15:48:47 steinchen postgres[2198]: [32-1] LOG: Verbindung authorisiert: Benutzer=dovecot Datenbank=xams-dovecot (...)

[Dovecot] [PATCH] POP3 CAPA command RFC violation
by Andrey Panin 22 Jul '04

22 Jul '04

Hello, looks like SASL capability reported by dovecot in response to POP3 CAPA command doesn't conforms with rfc2449 which says: Examples: C: CAPA S: +OK Capability list follows S: TOP S: USER S: SASL CRAM-MD5 KERBEROS_V4 S: RESP-CODES S: LOGIN-DELAY 900 S: PIPELINING S: EXPIRE 60 S: UIDL S: IMPLEMENTATION Shlemazle-Plotz-v302 S: . And later: The POP3 AUTH command [POP-AUTH] permits the use of [SASL] authentication mechanisms with POP3. The SASL capability indicates that the AUTH command is available and that it supports an optional base64 encoded second argument for an initial client response as described in the SASL specification. The argument to the SASL capability is a space separated list of SASL mechanisms which are supported. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Dovecot sends SASL capability as list of AUTH=FOO pairs. Looks like copy-paste from IMAP code. Patch attached. Best regards. -- Andrey Panin | Linux and UNIX system administrator pazke(a)donpac.ru | PGP key: wwwkeys.pgp.net

[Dovecot] namespaces and behaviour of LIST and SELECT with leading ~
by Tim Southerwood 21 Jul '04

21 Jul '04

Hi One weirdness when going through the code: (We are migrating from WU-IMAP and have users with a mixture of ~/IMAP/ and ~/Mail/ for storing mail - but all user INBOX=~/.email thankfully. IMAP client config is even more random and we have 1800 users. I have been playing with namespaces to translate various prefixes ala: default_mail_env = mbox:%h/:INBOX=%h/.email:INDEX=/var/cache/dovecot/%n # Note lack of IMAP ^^^ (So clients can use ~/IMAP or ~/Mail - we have a # historic mixture) full_filesystem_access = no namespace private { separator = / inbox = yes prefix = hidden = no location = mbox:.email } namespace private { separator = / prefix = hidden = no location = mbox:IMAP/ } namespace private { separator = / prefix = IMAP/ hidden = no location = mbox:IMAP/ } namespace private { separator = / prefix = ~/IMAP/ hidden = no location = mbox:IMAP/ } User tstest has INBOX in ~/.email and mail folders in ~/IMAP/ all in mbox format: Here's a sample conversation: * OK dovecot ready. 1 login tstest ******* 1 OK Logged in. 1 list "" % * LIST (\NoInferiors \UnMarked) "/" INBOX * LIST (\NoInferiors) "/" "Trash" * LIST (\NoInferiors) "/" "Queue" * LIST (\NoInferiors) "/" "Sent" * LIST (\NoInferiors) "/" "Drafts" * LIST (\NoInferiors) "/" "Blah" 1 OK List completed. Good 1 list "" IMAP/% * LIST (\NoInferiors) "/" "IMAP/Trash" * LIST (\NoInferiors) "/" "IMAP/Queue" * LIST (\NoInferiors) "/" "IMAP/Sent" * LIST (\NoInferiors) "/" "IMAP/Drafts" * LIST (\NoInferiors) "/" "IMAP/Blah" 1 OK List completed. Good 1 list "" ~/IMAP/% 1 OK List completed. Oops (being caught by mbox_is_valid_mask as prefix begins with ~ and the client supplied prefix is being tested, not the virtual one after namespace prefix substitution) But... 1 select Blah * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted.* 5 EXISTS * 0 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1090326264] UIDs valid * OK [UIDNEXT 6] Predicted next UID 1 OK [READ-WRITE] Select completed. Yes 1 select IMAP/Blah * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted.* 5 EXISTS * 0 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1090326264] UIDs valid * OK [UIDNEXT 6] Predicted next UID 1 OK [READ-WRITE] Select completed. Yes 1 select ~/IMAP/Blah * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted.* 5 EXISTS * 0 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1090326264] UIDs valid * OK [UIDNEXT 6] Predicted next UID 1 OK [READ-WRITE] Select completed. Oo - this works despite the ~ I would argue that with namespace {} directives, the behaviour of SELECT is correct. I would suggest that it may be better to test the final translated path thus: if full_filesystem_access = yes let anything go. else make sure that final translated mail path is identical OR a subpath of the default_mail_env mbox folder path. (INBOX is a special case and can be matched as well) This is a suggestion - what do you think? I'd have a go myself but I don't yet feel competant with the dovecot code. Best wishes Tim -- Tim J Southerwood

[Dovecot] dovecot-1.0-test27 crash on FETCH
by Wouter Van Hemel 21 Jul '04

21 Jul '04

Hello, I've got a crash with -test27 on a FETCH, just after logging in. Attached are the mailbox (1 message only), logs, sniffed session, testcase and core dump backtrace. If the dovecot.conf is needed, just ask (it's pretty much the default configuration). Maybe this has just been fixed in -test28, in which case you can just delete this email. :) Btw, it's rather irrelevant, but does anybody know a good way to read the qmail alias user's mailbox remotely (imap? The only way seems by assigning a password to the account... Regards, wouter

[Dovecot] Fatal: Unknown userdb type 'pgsql'

Hello, I'm trying to use postgres authentication with dovecot on a linux system running Fedora Core 2.

RE: [Dovecot] Probably a bad idea but.....
by Mark Lidstone 21 Jul '04

21 Jul '04

Hi everyone, Just done some testing and thought I'd share the results. I've successfully moved a few test emails from a Mercury/32 Windows server to Maildirs. I created an IMAP folder for each user ".INBOX.Old\ Mail" and put the email in there. It's accessable via IMAP but does not show up as a new email when the user uses POP3 to collect their email - exactly what I was after (they're all using POP3 at the moment, but I will be pushing them to move to IMAP at a later date). I'm going to copy the rest of the email in one go overnight so if you don't get another email from me on here assume it worked. Thanks for the help Timo.

You'll lose message flags, but as long as the filenames don't contain ':' characters you can just copy them.

[Dovecot] Probably a bad idea but.....
by Mark Lidstone 21 Jul '04

21 Jul '04

Hi all, I've got a few users I'm trying to migrate from a Mercury Mail server to a dovecot IMAP/POP3 setup. I was hoping to use some sort of imap-copy type script to move email from the Mercury server to dovecot server, but the Mercury box is running so slow it's impossible. Mercury stores mail in a similar way to Maildirs, different folders with separate files for each mail, stored in plaintext RFC822 format. How sensible would it be to copy the files over from the Mercury server to users maildirs on a Linux server? The filenames are in a different format but I don't know if that would cause a problem?

[Dovecot] imap support question
by Tom Allison 21 Jul '04

21 Jul '04

OK, I'm actually trying to write something which interacts with IMAP. I'm trying to run the FETCH command and it goes OK, but I'm wondering how I might be able to call both RFC822.SIZE and BODY[HEADERS.FIELDS(..) in the same call. Right now I'm only able to get this to work with two calls to the server. I was hoping to avoid making two calls. Any suggestions? (I realize it isn't exactly "on topic" for the mailing list, but I can't think of any list I'm on that's even close to the topic)

[Dovecot] Newbie question: configuration for virtual users
by Rory Campbell-Lange 21 Jul '04

21 Jul '04

Hi! I'm looking forward to deploying dovecot as an IMAP server. I did some research into the various options and it looks like dovecot is the right daemon for me. I'll be using it with Exim. I am running a few tens of users on my server, most of them small numbers of people part of a small company, e.g. example.com. At present I have exim delivering to mbox in each virtual user's mail folder. So, for chris, john and mandy @ example.com, I have /home/example/Mail/ chris john mandy All of the users in example.com run under the same uid and gid (example). I like to separate these 'virtual' users from the real system users for security reasons. I presently serve up these mboxes via teapop, which allows for per-domain configuration. I couldn't find a similar setup after a cursory read of the config file examples on the dovecot website. I'd like some advice on how to support different non-system users under dovecot, ideally storing mail in a similar configuration to above, except (presumably?) that the user files will be under each user name? Thus: /home/example/Mail/ chris/ john/ mandy/ I may use postgresql to store user configuration data if appropriate. Advice gratefully received.

[Dovecot] Idea to enhance migration from UW-Imap
by Klaus Steinberger 20 Jul '04

20 Jul '04

Hello, i want to migrate from UW-Imap to dovecot, but want to avoid changing clients (that would be really hard to do). All my users have their Mailboxes in ~/Mail. My idea would be now to strip off "Mail" from the imap commands, so that both a client which prepends "Mail" as well as one who doesn't would see the same mailboxes. Can somebody give me a hint where in the dovecot source I could do that stripping (at best some central function, so this stripping has to be done just one time). I would be glad to make the changes and then to contribute that change, I just need a hint where in the sources I will find the right place.

[Dovecot] 1.0-test29
by Timo Sirainen 20 Jul '04

20 Jul '04

http://dovecot.org/test/ Huh, I almost got stuck with this one. It's boring to do larger rewrites to things that already kind of work. This time it was rewriting how caching headers work. The old way was kind of ugly and it didn't really guarantee the order in which cached headers could be fetched. So there were a few theoretical problems that could have broken things. 0.99.10 didn't support caching headers at all, so it didn't have this problem. I think the new caching code is finally nearly finished. Just a few small things left and it's done. This release also fixes some other crashes and problems. I've been running it nearly an hour now without problems :)

[Dovecot] Dovecot LDAP Auth strange mailbox behavior

Hello everyone. I have setup a Debian Sarge server, with openldap, postfix, and Dovecot. I have been able to fix all the problems that have been logged thus far, and it seems to work. I am able to use a mail client to login to the pop3 server. The authentication works, and it logs as a successful login, but no messages download. I get a response: No New Messages. I have checked the user's maildir directory, and there are mails sitting in the new directory, so it should download. Anyone have any clues? Thanks in advance, Ryan

[Dovecot] Authentication Problems.
by Tom Ray [Lists] 18 Jul '04

18 Jul '04

Hey- I'm kinda new to Dovecot and I'm trying to do something and it seems I've hit a wall. I put together a server with Fedora Core 2, Exim 4.34, and Dovecot 0.99.10.6 and I need support mail for multiple domains so this is how I have my virtual setup: Virtual Aliases Files: /var/virtualdomains/$domain/etc/aliases Virtual Accounts Passwd File: /var/virtualdomains/$domains/etc/passwd with the following layout: user:passwd:uid:gid:Virtual User:/var/virtualdomains/domain.com/mail/user:/dev/null Virtual Mailboxes: /var/virtualdomains/$domain/mail/$user I got exim working without problem but when I tried to login via IMAP on Dovecot I'm getting 'a001 NO Authentication failed.' Now I have this setup in dovecot.conf: default_mail_env = mbox:/var/virtualdomains//%d/mail/%n/:INBOX=/var/virtualdomains/%d/mail/%n auth_userdb = passwd-file /var/virtualdomains/etc/virtpasswd It's my understanding that Dovecot can't parse out the domain name in the auth_userdb command so I modifed my setup to use just the one password file and modified it to this; user@doman.com:passwd:uid:gid:Virtual User:/var/virtualdomains/domain.com/mail/user:/dev/null Ownership/Group: -rwx------ 1 dovecot dovecot 36 Jul 13 18:41 passwd Is there a setting I have wrong, a step I'm misisng, a permission I don't know about....let me know if there is any other information you might need and I will provide it.

[Dovecot] Testimonial
by Kenneth Porter 16 Jul '04

16 Jul '04

I just switched my main "library" of over 100 mailboxes from UW-IMAP on a gutless wonder with 600 BogoMIPS and 200 MB to a box with 2000 BogoMIPS and 1 GB, and also switched from UW-IMAP under RH7.2 to Dovecot under Fedora Core 2. Using Mulberry on Win2k as the client, it used to take several minutes to check for new mail in all folders. Now it takes just 2-3 seconds. Opening large folders with 100's of messages used to take a dozen seconds or more, and is now down to at most a second or so. IMAP is no longer frustratingly slow. Now to figure out what to do with all my spare time....

[Dovecot] can't see IMAP folders - Fedora Core 2
by Ralph Brown 15 Jul '04

15 Jul '04

Recently, I upgraded (switched) to Fedora Core 2. Previously, I was running Fedora Core 1, with Cyrus-IMAP, and life was good. Now, I can not see any of my folders. I suspect it is a simple dovecot.conf configuration edit, but i'm not experienced enough with it to make the correct edits. I am using Postfix with Dovecot. My mail directory is; /home/(user)/mail snip from the conf file; --------------------------- You can also limit a width of string by giving the number of max. characters # after the '%' character. For example %1u gives the first character of # username. Some examples: # # maildir:/var/mail/%1u/%u/Maildir # mbox:~/mail/:INBOX=/var/mail/%u # mbox:/var/mail/%d/%n/:INDEX=/var/indexes/%d/%n # #default_mail_env =/home/%u/mail ---------------------------- Thanks in advance for any suggestions.

outlook-pop3-no-nuls didn't actually work in rc1. Works now. v0.99.10.7 2004-07-14 Timo Sirainen <tss(a)iki.fi> + Added outlook-pop3-no-nuls workaround to fix Outlook hang in mails with NULs. + Config file lines can now contain quoted strings ("value ") - If client didn't finish downloading a single mail in 30 seconds, Dovecot closed the connection. This was supposed to work so that if client hasn't read data at all in 30 seconds, it's disconnected. - Maildir: LIST now doesn't skip symlinks

[Dovecot] Shared folders
by D Canfield 13 Jul '04

13 Jul '04

Several months back shared folders based on ACL's were discussed here, and it was mentioned that support for these had been added to CVS. Since the web site still says shared folders aren't implemented, I just wanted to check and see if the shared folder code is just in CVS for a future, post-1.0 release, or if the code ever made it into any of the 0.99x relases. Thanks DC

[Dovecot] FreeBSD and MySQL error

Greetings I have been installed dovecot-0.99.10.6 in my FreeBSD 4.10 with WITH_MYSQL=1 , but when I try to configure it to use mysql.conf file: auth_userdb = mysql /usr/local/etc/dovecot-mysql.conf auth_passdb = mysql /usr/local/etc/dovecot-mysql.conf the program gives me the next error: dovecot: Jul 13 10:49:03 Info: Dovecot starting up dovecot-auth: Jul 13 10:49:04 Fatal: Unknown userdb type 'mysql' dovecot: Jul 13 10:49:04 Error: Auth process died too early - shutting down dovecot: Jul 13 10:49:04 Error: child 13659 (auth) returned error 89 Somebody knows why?

[Dovecot] [patch] gssapi support
by Colin Walters 13 Jul '04

13 Jul '04

Hi, I've been working on a patch for GSSAPI (Kerberos) support. It seems to work pretty well for authentication (I've tested it with Evolution, fetchmail, and mutt). I have also been working on implementing integrity/confidentiality protection. Unfortunately not many clients support this - the only one I've found really is mutt, which seems to disconnect from the server for some unknown reason not long after a Kerberos-secured conversation. I'm still trying to track that down. But anyways the patch is far along enough that I think it's worthy of review and testing. Some todo items: 0) Track down bug preventing mutt from working 1) Audit integrity proxy a bit more 2) Make sure we're handling mechanisms other than Kerberos 3) Test with more clients

i'm trying to use timo's postfix-2.1.2-dovecot-auth.patch on freebsd4 with postfix-2.1.4 the problem is that smtpd_sasl_glue.c tries to include stdint.h which isn't present with fbsd4. is there another lib that'll provide the same functionality? i've tried using inttypes.h but i don't know of any other similar ones stdint is in fbsd5 apparently but i'm still scared of it have any ideas?

[Dovecot] mailbox problem

Hi guys, I use a virtual mailbox setup with dovecot/postfix. Which reside under /virtual. I get an error message which doesn't return anything interesting in Google. I get this: imap(user(a)domain.com): File isn't in mbox format: /virtual/domain.com/user/imapd/Trash I have no idea on how to fix this. I seem to be able to delete messages though. But I'd like to repair this, since I like to have clean logs ;) Thanks for your time, -- Jean-Francois Theroux Systems administrator 514.726.3732 PrivalODC http://www.privalodc.comp

[Dovecot] 1.0-test28
by Timo Sirainen 12 Jul '04

12 Jul '04

http://dovecot.org/test/ - Fixed some crashes with cache file. THREAD and SORT especially crashed it. - Fixed the SSL infinite looping in login processes - Recent flags are working again with maildir. Almost with mbox too. - Maildir code moves mail into cur/ directory directly if the mail contains flags, so we don't violate maildir spec anymore by placing them into new/ with the flags. Although.. now that I think about it, that breaks recent flags, as only mails in new/ are treated as being recent.. Well, I guess next version implements my another idea for it: Store flags only into index and keep the file in new/, flags will be added when the file is moved to cur/. Non-Dovecot MUAs don't see the flags in the mean time though. - SIGHUPing dovecot master process finally reloads configuration completely and without crashing - Added --exec-mail parameter to dovecot. It can be used to launch imap/pop3 processes with configuration from dovecot.conf - Changed client_workarounds to imap_client_workarounds and pop3_client_workarounds. Added the first pop3 workaround: outlook-no-nuls

[Dovecot] NUL characters in POP3 conversation cause Outlook to hang
by Matthew Reimer 10 Jul '04

10 Jul '04

We're being bitten an Outlook bug [1,2] that is triggered by a NUL character in a message being sent through POP3. I see that dovecot's imap implementation converts 0x00 to 0x80, but this conversion is not done for POP3. Would it be possible to add an option to do this mapping for POP3 as well?

Hello, I would like to allow users to login as user(a)domain.tld instead of providing their login name; I'm coming from the sendmail/qpopper land and am trying to migrate to postfix/maildir/dovecot one step at a time and I've been able to find a way to do most of what I want except for the above requirement. Do I have to use a SQL server or is there any way to easilly map an email address to a mailbox or even a maildir? Thank you. -Vlad

[Dovecot] Re : Permission denied
by Frédéric Sapin 09 Jul '04

09 Jul '04

Hello Timo, I'm using linux Fedora Core 2. The permissions are : drwxrwxrwt 2 root mail 32 2004-06-16 04:45 /var/spool/mail/ These permissions are made buy the command chmod a+rwxt /var/spool/mail. So if someone wants to erase the /var/spool/mail directory, it's possible unfortunately. If there are theses permissions the user can receive his mails but it's dangerous I think. And if I modify the dovecot.conf file : mail_extra_groups = mail and if the permissions are the initial permission, and if I enter chmod +t /var/spool/mail the user can't receive his mail. Thanks Frederic

[Dovecot] passing remote ip to pam
by dean gaudet 09 Jul '04

09 Jul '04

to improve forensic log info i want to set the PAM_RHOST value to the remote ip (which pam logs as rhost=foo in failure messages). i didn't look to see if anything has been done in this way on CVS because i'm still on 0.99.10.6. below is a bit of a hack. in some sense the remote_ip might make more sense in the AUTH_LOGIN_REQUEST_NEW packet rather than the continue packet... but that looked like i'd have to change more code :) btw -- is there anything which stops mech_plain_auth_continue from doing a somewhat unbounded pstrdup if you send "a\0b" for the auth string?

[Dovecot] Permission denied

Hello all, I'm a new user of dovecot and I've got a permission denied problem. I've read the VarMailDotLock wiki paper but there is still a security problem. If I enter : chmod a+rwxt /var/spool/mail it works but I think it's very dangerous to have thaht rights. So I've tried to edit the dovecot.conf file and to change the mail_extra_groups = mail and to change the rights : chmod +t /var/spool/mail but it doesn't work ! The mails are in /var/spool/mail/unix_user_name Could you please help me to configure the /var/spool/mail to have a good security and to allow people to receive their mails ? Thanks Frederic

[Dovecot] a yum install with mysql support??
by alex＠alution.com 09 Jul '04

09 Jul '04

Hello, Well im guessing i have already answered this question myself. Im using FC1 and installed dovecot the easy way (yum install dovecot) It has stated that it installed version 0.99.10.5 and from what I have looked at in the mailing list archives, this version SHOULD have mysql authentication support. However what I don´t know is if by installing the yum package it will allow this support. Im guessing that I will have to install it the real way, as if I take a look in the logs, it states... ============== dovecot-auth: "Jul 09 00:37:38 "Fatal: Unknown userdb type 'mysql' dovecot: "Jul 09 00:37:38 "Error: Auth process died too early - shutting down dovecot: "Jul 09 00:37:38 "Error: child 31532 (auth) returned error 89 ============== Am i correct in thinking this? Or is there something else a miss?? Thanks Alex

[Dovecot] Peer Config Review
by Eric Kahklen 07 Jul '04

07 Jul '04

I am trying to setup a mail server using Postfix and Squirrelmail. The mail server will ONLY use webmail for access. I will not be using any email clients other than Squirrelmail.

[Dovecot] Logging "issue" with PAM authentication
by Steve Johnson 07 Jul '04

07 Jul '04

Hi, We currently have a postfix/dovecot setup using nss_ldap with PAM for authentication. Everything is working fine, but there are excessive "error" messages in /var/log/messages that I'd like to prevent from happening. Since auth_userdb defaults to passwd and that our users are not in the passwd file, we get the following message everytime a user logs in: Jul 7 13:34:37 hostname dovecot(pam_unix)[32206]: check pass; user unknown Jul 7 13:34:37 hostname dovecot(pam_unix)[32206]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost= We of course also get the input that a user has logged in, in /var/log/maillog: imap-login: Jul 07 13:34:37 Info: Login: username [xxx.xxx.xxx.xxx] I've tried changing auth_verbose to no, and I still get those messages. Is there any way to prevent this from happening? Thanks a lot, Steve Johnson

[Dovecot] 1.0-test25 with new cache file code
by Timo Sirainen 07 Jul '04

07 Jul '04

http://dovecot.org/test/ Pretty much the only change since test24 is a redesign of how cache file writing works. Reading works as before - without locks. Before (in 1.0-tests, 0.99 was worse) we used to just try to lock it. If it failed, we just didn't update cache. If it didn't fail, the lock could have been kept a long time. For example if a user was downloading a 10MB mail, the lock could have been kept the whole time and no-one else could have modified the cache. The old behaviour wasn't actually too bad, as normally it didn't matter if something couldn't be written to cache. It would have been the next time, all it did was cost some I/O. The new behaviour is more reliable as the locks are kept only a very short time. It works by first writing the updates only into internal 32kB buffer. Once the buffer gets full, or the transaction completes, it's written to disk. When buffer gets full, space is reserved from the cache file for the current transaction. The amount of space is more than is needed for writing the internal buffer, so we don't have to lock the cache file every time the buffer gets full (and so we don't need a huge buffer). Once transaction completes, we lock the cache again and try to free the extra reserved space we have left. If multiple processes weren't updating the cache file at the same time, the freeing should be as simple as decreasing "used_file_size" field in header. Alternatively we'll update a linked list of "holes" in the file. When reserving space, we first try to use those holes instead of appending to end of file. Pointers to new cache records are also written to transaction log at the end of cache transaction. They'll get written to index at next sync after which they become visible to other processes. Each cache record contains a pointer to previous record, so there can be multiple cache records for a single message. The bad thing with the new logic is that nothing prevents two processes from writing the same cache records and so using twice as much space as necessary. But I don't think it's much of a problem. They'll go away at next cache compression. These changes also make it quite simple to make cache file work with shared filesystems. I'd just need to implement some kind of internal caching buffer which remembers what parts of file are read into memory. These changes also make it possible to easily and reliably store X-UIDL headers into cache file, where the POP3 UIDL command could quickly get them. Not in this release yet, though..

(I'll send a public reply, the last question could need input from others) Well, it's not compatible with any RFC of course, but I don't think it would violate anything? I'd just rather like to avoid unnecessary code bloat. Well, except now that I thought about the logic instead of just the code, there are problems. APOP prevents replay attacks by sending different timestamp in greeting, but you're sending the greeting to dovecot-auth as user input to APOP authentication mechanism. So, a user could simply say "AUTH APOP" and send wanted timestamp as input. One way to fix this would be to disallow APOP mechanism to be used with AUTH command in pop3-login and require that the request was done with POP3 protocol. But I think that's pretty ugly kludge. It also requires that processes connecting to dovecot-auth are trusted, which is something I've tried to avoid as much as possible. So dovecot-auth doesn't really know if it's pop3-login which connects to it.. Better fix would be to get part of the timestamp from dovecot-auth itself. It could send a growing ID number as handshake which would be used as part of the timestamp, and APOP mechanism processing would check that timestamp really contains the ID. So timestamp would be <authid.unixtime@hostname>. That also makes the PID go away, which was another thing I would have suggested. POP3 RFC also says: It is conjectured that use of the APOP command provides origin identification and replay protection for a POP3 session. Accordingly, a POP3 server which implements both the PASS and APOP commands should not allow both methods of access for a given user; that is, for a given mailbox name, either the USER/PASS command sequence or the APOP command is allowed, but not both. But I don't know if there's any nice way to do it, except perhaps by defining APOP password scheme which would actually be plaintext but wouldn't work with anything but APOP authentication. Do any other servers prevent it either?

I uploaded 0.99.10.6 to sid. Owing to the importance of the dot lock fix, I've tried to have this pushed to sarge quickly. Let's see how that goes. I've prepared a backport of 0.99.10.6 to woody which should be showing up on www.backports.org soon hopefully. In the meantime, if you desperately need it and don't mind working out dependencies yourself, you can find it at http://www.braincells.com/backports/ I uploaded 1.0test18 to http://src.braincells.com/dovecot-test/ (I'll do test20 tomorrow) I told Timo I'd port dovecot's gnutls support from gnutls7 to gnutls10 but I have absolutely no time for it so if someone would volunteer, contact me, I'd really appreciate it. -- Jaldhar H.

[Dovecot] 1.0-test24 and some mbox benchmarking
by Timo Sirainen 02 Jul '04

02 Jul '04

http://dovecot.org/test/ Again only mbox fixes. I found some more bugs which could have also caused some of the mbox problems that people reported. They were found when I today thought I'd again do a bit of testing with my favourite 1.4GB mbox. Then I thought I might as well see how it compares against UW-IMAP. First a bit of explanations how they work internally: Dovecot 1.0-test24 ------------------ Dovecot works by trying to do everything in one "sync" function. It reads new mails, inserts missing headers, writes header modifications and expunges messages. Dovecot leaves 100 bytes of padding in every mail's headers, which it can use to avoid moving the rest of the file forward when it needs to insert space. However, if there's not enough space (and with new mails there isn't), it needs to do the moving. Moving is done by first reading messages and counting how many bytes we're short. Once we've seen enough padding we'll rewrite those messages. If we read until end of file, we'll grow the file and rewrite the messages. Rewriting is made backwards, so we don't have to do much buffering, and in case the rewriting gets interrupted (crash, power loss, etc.) the data loss is very small, a few kilobytes maximum. UW-IMAP 2004 ------------ UW-IMAP first only reads the mbox with SELECT, rewrite is only triggered by LOGOUT, EXPUNGE and CHECK commands. UW-IMAP also inserts padding, but less than Dovecot. It tries to get added headers to fit into 50 bytes, and what's not used is left as padding. Normally this seems to get it around 15-20 bytes of padding. Perhaps I should shrink it from Dovecot too. Rewriting works by reading the file forward into buffer and writing the changes as needed. This is quite fast, but it means the buffer can grow large, and if the rewrite gets interrupted everything in the buffer gets lost. In my test mbox this would have been 23MB of lost data, but normally much less. Benchmarks ---------- I simply rewrote a 1.4GB mbox containing 361052 mails, Linux kernel mailing list archives from years 96-02. Computer is Athlon XP 2700+ with 1GB of memory. reads/writes were counted using Linux's iostat command. Nothing else was being used in that partition, so the numbers should be accurate. Except UW-IMAP's read count is a few blocks too much because I got tired of waiting it and started looking into the mbox to see how far it had gotten. Read counts could also be somewhat wrong if some of the mbox was already in buffer cache. I tried to trash it anyway by catting 2x4GB of data into /dev/null. Kernel used around 900MB of memory for caching. Total CPU times may also be a bit off, as the computer was being used at the same time. Dovecot 1.0-test24 ------------------ reads : 4007432 blocks = 1956 MB writes: 2947381 blocks = 1439 MB original mbox : 1420611590 B = 2774632 blocks = 1354 MB rewritten mbox: 1472684487 B = 2876336 blocks = 1404 MB indexes : 14452732 B = 28227 blocks = 14 MB 7221164 dovecot.index 10436 dovecot.index.cache 7221132 dovecot.index.log (this will be truncated after a while) - 16064 VSZ, 8012 RSS after SELECT completed - 14MB is mmaped index files - 216kB heap left of which 70kB actually in use - heap usage was 25MB VSZ/RSS constantly while syncing, but allocations were so large that libc used anonymous mmap()s so they got dropped after sync - VSZ peaked at 32MB, most likely because index file(s) were temporarily being mmap()ed more than once - 63.37s user - 16.56s system - 24% cpu - 5:22.75 total UW-IMAP 2004 ------------ Reading: - memory: 70044 VSZ, 67724 RSS - CPU: 7s user, 53s total Totally: reads : 5549640 blocks = 2709 MB writes: 2875581 blocks = 1404 MB original mbox : 1420611590 B = 2774632 blocks = 1354 MB rewritten mbox: 1444411190 B = 2821115 blocks = 1377 MB - 93416 VSZ, 91120 RSS - 2295.81s user - 23.99s system - 96% cpu - 39:57.90 total Notes ----- Not counting Dovecot's indexes UW-IMAP wrote 21MB less. But Dovecot wrote 27MB more padding, so just by shrinking it Dovecot would have written 6MB less data. Also because Dovecot writes the file backwards, it needs to do some extra jumping around and overlapping writes, but I guess OS nicely merged them. I'm not exactly sure why UW-IMAP uses so much CPU for rewriting, but it does and so Dovecot is over 7x faster in total (with 36x less CPU). Dovecot should also support delaying the rewrite. This is mostly useful for POP3 clients which deletes all the mail at logout, so they won't need the rewriting at all. Dovecot also writes all flag changes to disk immediately while UW-IMAP leaves it later to do more at once. That results in less total I/O as well.

[Dovecot] 1.0-test22 - maildir fixed?
by Timo Sirainen 02 Jul '04

02 Jul '04

http://dovecot.org/test/ Well, remember when I said: > Here you go, maildir syncing problems finally fixed (I hope). Well, > except there's this "new-dir-only syncing" optimization which I'm not > really sure if it works as it should. Just before I found the expunge bug in index, I was trying to fix the new-dir-only syncing because the code looked wrong. Then I figured out the indexing problem and thought maybe this one wasn't broken after all, and then forgot about it. Finally after lots of debugging, I came to same conclusion again. The code was wrong, and cause of the remaining "Maildir sync: UID < next_uid (312 < 3)" errors. So, please try and see if you still can break this release. Other changes include some crashfixes for cache file and fix for mbox which kept constantly rewriting headers for \recent messages if we had selected the mailbox as read-only (EXAMINE, STATUS).

[Dovecot] 1.0-test23 and caching decisions
by Timo Sirainen 30 Jun '04

30 Jun '04

http://dovecot.org/test/ mbox fixes mostly. Began some other things, but none of them actually work yet: - Use X-UIDL header in mboxes for POP3 UIDL list - Cache file compression - Some cleverness for cache file for figuring out what to cache Well, I might as well explain the last one now. Users can be divided to three groups: 1. Most users will use only a single IMAP client which caches everything locally. For these users it's quite pointless to do any kind of caching as it only wastes disk space. That might also mean more disk I/O. 2. Some users use multiple IMAP clients which cache everything locally. These could benefit from caching until all clients have fetched the data. After that it's useless. 3. Some clients don't do permanent local caching at all. For example Pine and webmails. These clients would benefit from caching everything. Some locally caching clients might also access some data from server again, such as when searching messages. They could benefit from caching only these fields. After thinking about these a while, I figured out that people who care about performance most will be using the upcoming Dovecot LDA anyway which updates the indexes/cache immediately. In that case even the first user group would benefit from caching the same way as second group. LDA reads the mail anyway, so it might as well extract some information about it and store them into cache. So, group 1. and 2. could be optimally implemented by keeping things cached only for a while. I thought a week would be good. When cache file is compressed, everything older than week will be dropped. But how to figure out if user is in group 3? One quite easy rule would be to see if client is accessing messages older than a week. But with only that rule we might have already dropped useful cached data. It's not very nice if we have to read and cache it twice. Most locally caching clients always fetch new messages (all but body) when they see them. They fetch them in ascending order. Noncaching clients might fetch messages in pretty much any order, as they usually don't fetch everything they can, only what's visible in screen. Some will use server side sorting/threading which also makes messages to be fetched in random order. Second rule would then be that if a session doesn't fetch messages in ascending order, the fetched field type will be permanently cached. So, we have three caching decisions: 1. Don't cache: Clients have never wanted the field 2. Cache temporarily: Clients want this only once 3. Cache permanently: Clients want this more than once Different mailboxes have different decisions. Different fields have different decisions. There are some problems, such as if a client accesses message older than a week, we can't know if user just started using a new client which is just filling it's local cache for the first time. Or it might be a client user hasn't just used for over a week. In these cases we shouldn't have marked the field to be permanently cached. User might also switch clients from non-caching to caching. So we should re-evaluate our caching decisions from time to time. This is done by checking the above rules constantly and marking when was the last time the decision was right. If decision hasn't matched for two months, it's changed. I picked two months because people go to at least one month vacations where they might still be reading mails, but with different clients.

Read-only mboxes seem to be working nicely now, so I installed latest CVS Dovecot to dovecot.org again to serve them. Allows either ANONYMOUS SASL logins, or plaintext logins with "anonymous" user and empty password.

[Dovecot] Sym links to subfolders?
by Kevin Cramer 24 Jun '04

24 Jun '04

I just installed dovecot 0.99.10.6 and I'm trying to use symlinks for subfolders. I have my mail in ~/Maildir and I want to make symlinks such as from .Sent to ~/Mail/Sent. All of these folders are maildir and the permissions are correct. I've searched the list and I cannot find anything stating that it should not work. In fact I've seen posts that claim it should work. However, it does not work for me and looking at maildir-list.c around line 101, it appears that it is only checking for directories and not for links. I'm doing this because I have it setup so I can use mutt directly against the maildir folders and so IMAP will work against them. It's worked great for over a year but I want to move it to a different machine and I wanted to switch from courier-imap to dovecot. Can anyone confirm that it works or not? Any ideas on how to address this issue? Thanks, Kevin

[Dovecot] customflags considered a folder?
by Peter Schuller 24 Jun '04

24 Jun '04

Hello, i just switched from courier-imap to dovecot on a machine. The transition was painless except for one issue - when using the "Check mail" feature of kmail, one gets the message: "Unable to get information about folder customflags. The server replied: internal error..." So it looks like the server isn't properly hiding the .customflags file for some reason. I googled and only found one person who had seen something similar, but no solution. This is with dovecot 0.99.10.5. Similarly, 'customflags' does show up as a folder when using mutt. How would I go about preventing this problem?

[Dovecot] 1.0-test20
by Timo Sirainen 22 Jun '04

22 Jun '04

http://dovecot.org/test/ One more for today :) Again mostly mbox fixes and optimizations. Don't try it with maildir because it crashes with COPY and APPEND commands. This release supports now UIDPLUS extension. It was mostly a side effect of making saving mails store the X-UID header immediately to mbox and adding the mail to index. So, a Dovecot LDA would finally make sense now. Besides keeping indexes updated, it could also ask user's home dir, uid and gid from dovecot-auth. Now, that combined with postfix-dovecot-auth patch, Dovecot would be very simple to install with Postfix :)

[Dovecot] 1.0-test21
by Timo Sirainen 22 Jun '04

22 Jun '04

http://dovecot.org/test/ Should work again with maildir. - Some bugfixes to indexes (possibly fixing the still persisting maildir sync errrors?) - Enabled cache file again. If client asks about something that can be cached for future, it's done. There's currently no smart logic about when not to do it or when to cache more than was asked for future use. Currently nothing is ever deleted from cache. Currently it's disabled if mmap_disable = yes. - Removed UIDPLUS extension after all. It needs more thinking with maildir, because for performance reasons new messages are given UIDs once at the end transaction rather than separately for each one. So, the UID would have to be 0 temporarily until transaction is committed. But the current API make the new messages visible without syncing, and then the sequences don't match anymore and we can't get the UIDs. So, this one needs thinking, mostly from API designing point of view.

[Dovecot] LDAP Bind
by Hervé Commowick - NewSports 22 Jun '04

22 Jun '04

hi all 2 Questions : - how not using the authentication bind feature of ldap server ? i rewrite checkpassword-ldap recently to use in bincimap server, and it take 3 lines to do this, so i don't understand how you don't use it. it is more powerful and more secure than retrieve pasword from the base and use crypto api to compare it. - is the dovecot server support the IMAPdir feature like bincimap or not ? thx for this great software, who replace my imap and pop3 server when it support that :) Vr.

[Dovecot] Delete message
by Marius Stan 22 Jun '04

22 Jun '04

Hello, I'm seeing that our favourite pop3 server only deletes the messages upon logoff: dele 1 +OK Marked to be deleted. quit +OK Logging out, messages deleted. Connection closed by foreign host. This is causing me some trouble with a certain webmail app. Is there a way I can instruct Dovecot to immediatelly delete a message ? 10x, Marius

[Dovecot] proxy plugin
by Timo Sirainen 22 Jun '04

22 Jun '04

I've updated the proxy plugin at http://dovecot.org/patches/1.0/quota.c. It doesn't exactly work, even against latest CVS Dovecot as it crashes in save/copy, but it shows how it's basically going to work. Pretty ugly to do objects with C, but works.. If you're interested about writing support for some specific quota backend (maildir++, sql, ..), now would be a good time to begin :) Well, the reason it crashes is because it needs to find out the message's size, but Dovecot doesn't yet really like being asked about messages that haven't been committed to index. I guess that needs to change, hopefully won't require too large changes. I think I'm going to merge mail-index-view and mail-index-transaction into same thing..

[Dovecot] The Status: header is forced
by Olivier Tharan 21 Jun '04

21 Jun '04

Hi, I started testing dovecot for our next POP/IMAP server (nearing production state), and noticed that the Status: header is always added, with a value of 'O' or 'RO'. This happens in `lib-index/mbox/mbox-rewrite.c'. This does not seem to happen in the Maildir case. Is the Status: header really needed in every case? This breaks mutt which displays mails with a 'O' flag instead of 'N'. My dovecot is 0.99.10.4 (FreeBSD port), but the behavior is still the same in the CVS version. -- olive

[Dovecot] 0.99.10.5 released

19 Jun '04

One more bugfix since rc2: - Maildir: synchronization might have sometimes set wrong flags to messages, or crash completely Quite rare because we were lucky before :) And list of all the changes one more time: v0.99.10.5 2003-12-27 Timo Sirainen <tss(a)iki.fi> + MySQL authentication, patch by Matthew Reimer + --with-moduledir configure option - mbox: APPEND reversed given \Draft and \Deleted flags - mbox: "LF not found" errors happened sometimes when X-IMAPbase header was updated. Possibly corrupted mbox sometimes. Thanks to Fabrice Bellet for finding this bug. - Custom flags couldn't be unset - Maildir: make sure ":2," is appended to filename when moving mails from new/ to cur/. - Maildir: synchronization might have sometimes set wrong flags to messages, or crash completely - Maildir: RENAME xx inbox.xx didn't result as uppercased ".INBOX.xx" directory which then couldn't be accessed - Don't crash with RAND_bytes() error messages anymore. This mostly happened with Fedora/RedHat.

[Dovecot] 1.0-test17
by Timo Sirainen 19 Jun '04

http://dovecot.org/test/ Just mbox fixes since 1.0-test16. The logic is simpler and more correct now. Can anyone break it anymore? I actually tested it a while with Evolution and several mailboxes and it didn't break at least immediately. :) Now maybe a few more days and I dare trying this thing myself with my real mboxes (yes, I'm still using them). Dovecot mailing list archives could soon be served with 1.0-tests too, as soon as I get support for read-only mboxes working again (storing and comparing MD5 summed headers).

http://dovecot.org/test/ Again mostly just mbox fixes. The good thing is that the code is only getting cleaner and more understandable with every release. But I think it's clean enough now that this release should work :) It also has checkpassword passdb support. Supporting it as userdb isn't yet implemented. I think I'll make some generic caching thingy, so that if passdb is same as userdb, they both could be queried from database in one query. Probably by allowing pass_query/pass_filter to return them.

[Dovecot] Maildir + Evolution
by mkortela＠cc.hut.fi 18 Jun '04

18 Jun '04

I don't know if this is an Evolution bug or not, but when I use the maildir format with Dovecot 0.99.10p2 (from OpenBSD packages collection) and connect to it from Evolution 1.4 using IMAP, Evolution displays subfolders incorrectly. It actually does not show any subfolders, only root folders with names like "Folder.Subfolder" and "Folder.Subfolder.Subsubfolder". There's no such problem when using traditional mailboxes. Is this an Evolution bug or one of Dovecot's? I had thought the IMAP protocol should act the same no matter which mail dir structure was used... -- Mikko Kortelainen mkortela(a)cc.hut.fi

I am relatively new to setting up mail servers and wondered how difficult it would be to add SSL to my current Dovecot & SquirrelMail setup.

But I'm seeing that a lot of these applications tend to sometimes access servers via IMAP, but they always seem to have a touch more information needed than might be for an IMAP session. An example is openwebmail. It authenticates very similar to how dovecot authenticates, with a userdb and passdb specifications. It reads directly off the disk for some of it's activities. As for squirrelmail, they seem to want a lot of information regarding the mail architecture (mbox, maildir, folder locations...) and I don't really see where this could come into play with an IMAP implimentation. So, not actually having read all 82 pages of RFC 2060 (but I did print them!), I'm trying to see what I might miss if I were to attempt a web mail application that was based entirely upon IMAPv4 with the only information known prior to connection is the server name. Kind of like my mail client. Will I get into trouble with mail directories/folders if I start accessing different IMAP servers other than dovecot? Can I discover this without any hints from the user? I'm not sure exactly what I'm asking for here, other than some thoughts on what I might have to watch out for or do without (when comparing to squirrelmail as an example). I know I'll have to do something different if someone wants an addressbook, but I'm not there yet.

[Dovecot] 1.0-test16 - nearing usable state
by Timo Sirainen 18 Jun '04

18 Jun '04

http://dovecot.org/test/ Here you go, maildir syncing problems finally fixed (I hope). Well, except there's this "new-dir-only syncing" optimization which I'm not really sure if it works as it should. The bug really was in index code as I was beginning to suspect. The good thing is that while trying to figure it out over the last several weeks I thought of many other potential problems (race conditions) which got fixed. Those would have been much harder to find than this one :) Finally I thought I'd stop looking at the code and just begin dumping tons of debugging data to see where exactly it goes wrong. After few hours of debugging I figured out it was because message was being removed from index but not from maildir. 5 hours of sleep later I woke up, thought a while, figured out where it must be, got up, half an hour more debugging and found it. :) Code merging two UID range buffers into one was buggy, inserting one line of code fixed it. So .. Maybe I'll finally start using this myself now. The next important problems seem to be some random error messages about index locking timeouts and some asserts in some situations.

Re: [Dovecot] IMAP and webmail applications

i thought squirrelmail would be way too much of an overkill for my needs also but i went for it. i'm using debian and i got the squirrelmail package installed and working within 15 minutes. what really makes life easy is that squirrelmail comes with a configuration utility (squirrelmail-configure). it was very easy to get things configured without worry about a lot of conf files :) i also like the many plugins that people have created for squirrelmail. it's also very simple to add these plugins into squirrelmail using squirrelmail-configure. i had originally been ssh and mutt to check my mail, but i decided it be nice to have a web front-end and squirrelmail /apache /dovecot /procmail /spamassassin /gotmail /getmail /fetchyahoo have been a good mix for me. the hardest part for me was figuring out procmail and not squirrelmail :) my 2 cents, dan > I've been hunting around for a webmail application other than > squirrelmail for reasons that really don't matter. > > But I'm seeing that a lot of these applications tend to sometimes access servers via IMAP, but they always seem to have a touch more information needed than might be for an IMAP session. > > An example is openwebmail.

[Dovecot] shared authentication
by Kevin 16 Jun '04

16 Jun '04

whats the recommended way to share a user auth info between dovecot and postfix? sasldb seems like it could work but nobody really seems to like using the giant mass that is sasl. i also cant find any information on actually getting dovecot to use sasl past the configure options. i looked at timo's patch for postfix to use dovecot-auth but it doesnt apply correctly on the 2.1 branch. so what are people using to share passwords between the two without using the system passwd?

[Dovecot] Return (revenge?) of the "pop-lock".
by Christian Balzer 16 Jun '04

16 Jun '04

Hello, The users here have been migrated to the new mail system with dovecot 0.99.10.5 (Debian package) on the backends. Storage is maildir, only pop3 access for now. I see very seldom occurrences (compared to the session wide pop lock of qpopper on the old system) like this: --- Jun 16 14:35:52 mb01 pop3(user(a)gol.com): Timeout while waiting for release of exclusive fcntl() lock for index file /mail/spool/mb01/9ef/f73/af.user/.INBOX/.imap.index --- These are people with slow connections and at least one large mail in the box, with their client aborting w/o terminating the session properly. I presume the timeout for this is hardcoded, as all the config parameters for timeouts are mbox related, rite?

[Dovecot] /var/mail dotlocking workaround
by Timo Sirainen 16 Jun '04

16 Jun '04

I added "mail_extra_groups" setting which can be used to give imap/pop3 process access to additional groups. So what this means is if you set it to "mail" you can finally remove o-w access from /var/mail directory. Leaving the sticky bit could still be a good idea, so there's no way users to be able to delete each others inboxes. Here's a patch against 0.99.10.5: http://dovecot.org/patches/mail-extra-groups.diff

[Dovecot] dovecot non-local users
by Tom Allison 16 Jun '04

16 Jun '04

From the docs: System without local users -------------------------- <snip> Having one uid per user would mean that in case of a security hole in Dovecot, the user still couldn't read other peoples mails. Use this if possible. ----- I don't quite understand this one. If you aren't a local user, what's the uid all about? Do I do something like: create a user for mydomain in /etc/passwd (eg: user:domain_dude, home:/var/dovecot) with a valid home/uid/gid. Plug in the uid/gid/home for domain_dude in the authentication and have a data structure of /var/dovecot/%d/%n/Maildir or %h/%d/%d/Maildir where %h = "/var/dovecot" via /etc/passwd. Something like that?

[Dovecot] review of my configuration
by Tom Allison 16 Jun '04

16 Jun '04

Over the last week I've set up dovecot and imap and imaps support. I've even tried to break it but it's been doing very well. Now I'm trying to set up a webmail interface. Rather than use the common squirrelmail, I thought I would try openwebmail. Mainly because it's written in perl, of which I am a big fan. However, I ran into some errors in openwebmail that actually may tie back to dovecot. Here's how: dovecot configuration userdb = /etc/passwd passdb = pgsql.... ---this allows me to use the $HOME, uid, gid from the passwd file and not have to carry two copies of it (/etc/passwd and pgsql) However, under openwebmail I don't seem to have this option as they are really determined to require a home, uid, gid for each user that logs in. As witnessed by the following line: Tue Jun 15 20:23:34 2004 - [31572] (unknown) tallison - userinfo error - auth_pgsql.pl, ret -3, Can't execute SQL statement: ERROR: column "uid" does not exist Sure looks familiar doesn't it? (see, it's relevant!) Since I was thinking that maybe it might be interesting to do some email set up to support multiple domains and users some day, and I want to try out the openwebmail sooner than that. I'm getting the impression that it might be easier if I just made the leap today and started to reconfigure everything for multiple domain hosting and all the cool stuff. Now, I can probably muddle through this without too much internal damage. But I keep getting stuck on one point. How can I filter the delivery of email like I do with procmail, when I am delivering mail to many users, none of whom have a /etc/passwd entry? Are there any alternative ideas on how to do this?

[Dovecot] flat file mailbox formats
by Timo Sirainen 15 Jun '04

15 Jun '04

I've tried to write the new mbox code in a way that it could be moved into generic flat-file library with mbox-specific code being implemented on top of that. The code would be useful for all formats that require modifying message headers to store the metadata. How many such are there? I suppose all such formats could be implemented by separating mails into 3 logical parts: - header ("From ...\n") - mail data (headers and body) - footer ("\n") Except keeping a separate header and footer is kind of annoying, my current code uses: - mail separator ("\nFrom ...\n") - first message header's skip counter: how many characters to remove from mail separator for the first message (1, for \n before the "From ..") - last message's footer Somewhat uglier, but I think all needed formats could be implemented with it? It's also simper and more efficient to implement.. Besides mbox, I know at least two variations which are used: AAAA-box: - I remember seeing this somewhere years ago, but I'm not sure if it's still used or if it has a real name.. - separator is four ^A characters (ascii 1) and LF - header skip counter is 5 - last message footer would be the same ^A^A^A^A\n dotbox: - mails are stored in SMTP format, ie. lines beginning with '.' are prefixed with another '.'. the '.' prefixes will have to be removed for IMAP, so this isn't as simple as others to implement. - separator is ".\n" - header skip counter is 2 - last message footer is ".\n" Any thoughts?

[Dovecot] Shared folders?
by Villalovos, John L 15 Jun '04

15 Jun '04

I haven't seen any info on this so I thought I'd ask. Is there support for shared IMAP folders? Quite a few people at work subscribe to the Linux Kernel Mailing List. I thought it would make more sense if there could be a shared LKML folder that they all could use. This would save disk space. Is this posssible? If so how? I am also looking into the idea of doing a local newsgroup of the mailing list but I don't have a news server software setup at the moment. John

[Dovecot] 1.0-test15 released
by Timo Sirainen 15 Jun '04

15 Jun '04

http://dovecot.org/test/ Maildir code is still having syncing trouble. I thought about fixing mbox code for a chance - if the same problems happen with it too then I at least know that the problems are in indexes instead of maildir syncing itself. So, the biggest change in 1.0-test15 is a new fully functional superfast mbox code. If you can make it corrupt your mboxes I'd like to know about that. I haven't tested it too much yet, but I haven't seen corruption for a while anymore. Superfast as in: - Syncing and modifying the mbox is done in one integrated loop, no more passing through the whole mbox multiple times. - If we know the mbox is synced and we need to modify it, we directly jump to the message(s) needing modification and change only them. This means that with upcoming Dovecot LDA the mbox never needs to be fully parsed. As long as you're not expunging old messages, mboxes with sizes of even gigabytes should be no problem. Still a few remaining issues though: - It gets to infinite loop with 0 sized message body. I'll fix this soon - Recent counters are broken - mbox lock should be kept two extra seconds after syncing. that is required so that we can be sure no-one else has modified the mbox (ie. mtime changes every time) - APPEND command doesn't yet update indexes directly, so they still trigger a full sync - keywords aren't implemented - UW-IMAP style "FOLDER INTERNAL DATA" message is almost supported.. but not quite yet. We're going to use it if it exists, but we won't insert one ourself. This also brings to my mind supporting some other flatfile formats.. Well, I'll write another mail about that.

[Dovecot] PAM_RHOST item
by Tom Alsberg 15 Jun '04

15 Jun '04

A little problem, which is bugging me: when using PAM authentication, Dovecot (0.99.5) does not set the PAM_RHOST item, so the PAM modules cannot know who the client is. We need this for some PAM module doing access control. Changing passdb-pam.c to pam_set_item it seems trivial, but I'm bugged as to how to get the client name from there. It seems not to be available in the auth_request strut or anything from there. I tried even adding an upwards reference from there to the struct client *, but then I see that there are three structs named client and two structs named auth_request, and somehow I got into trouble of passing it cleanly. Any help or guidance for it is greatly appreciated. (I know Dovecot 0.99 is not really under development and such stuff is done in Dovecot 1.0 now, but that's not yet stable and for now we're using 0.99 where it would help).

[Dovecot] Default domain ?
by Marius Stan 15 Jun '04

15 Jun '04

Hello, I'm in the process of migrating from qpopper to dovecot and I've stumbled upon the least expected thing: In qpopper I can specify a 'default domain', which will be used if an user will only issue his username (not the whole email address) when logging in. Because of this, the users in my main domain don't use the whole email address when getting their mail. I'd hate to have to call each of them and guide through their OE menus to fix this issue, so I must ask: Is there any way at all of specifying a default domain in dovecot ? Thanks, Marius

[Dovecot] Wishlist item, POP3 welcome message
by Christian Balzer 15 Jun '04

15 Jun '04

Hello, With qpopper you get something like this after a successful login: --- +OK test has 6 visible messages (0 hidden) in 11822 octets. --- This gives a clueful user or support people a quick status about the size of this mailbox, very helpful in full quota scenarios. Would be nice if the next dovecot would have such a feature as well. I doubt the same is (easily) applicable for IMAP (though would be trivial once maildirsize is supported). Another thing would be PIPELINING for POP3, but I doubt it's all that helpful in this day and age of bountiful broadband.

[Dovecot] breakin' dovecot
by Tom Allison 14 Jun '04

14 Jun '04

I know this is cruel, but I figured out a way to break dovecot, temporarily. The really great news is that it recovers nicely. I'm also not sure if anything can be done about this, since I've seen the same thing happen with courier-imap, uw-imap, and maybe cyrus-imap. I used cyrus-imap for such a short period of time that I didn't get to really test it much. how to... (this was done on a fast ethernet network) get a folder with some 1,000+ unread/unseen emails. pop in with mozilla mail and wait for it to download all the mail information from ther server. press and hold the delete key. After about 300 emails being deleted, the imap server will appear to "freeze" and the "M" will keep cycling as if it's doing something. This will not recover until I move off the directory and return to it. hold delete key and repeat. If you do anything less than holding it down, it probably won't fail. It's a timing issue. I'm really not sure if it's even worth looking at. I'm not trying to identify this as a bug/defect/anything. But when I get a new piece of software I am really interested in what it does when it chokes. An old boss of mine would take my user applications and test them my rolling his hands across the keyboard for about a minute and if it hadn't crashed or entered bad data, it was a success. Please note that when I did this under courier-imap, it would stop refreshing itself from any/all directories until I logged out ( quit mozillia ) and logged back in again. So I would consider this to be a vast improvement in that regard. I should check what it logs when this happens, my guess is...nothing because it's frozen.

[Dovecot] Fedora dovecot Testing Needed
by Warren Togami 12 Jun '04

12 Jun '04

http://people.redhat.com/wtogami/temp/dovecot/ dovecot-0.99.10.5 binary packages for FC1 and FC2 are available here. I need feedback from Fedora users with THESE ACTUAL BINARIES before pushing them to official updates. Note: This does not solve the SSL related crash issue. That requires a patch to OpenSSL or kernel. I am still trying to convince the maintainers to patch it. Warren Togami wtogami(a)redhat.com

[Dovecot] folders via softlink
by Chris Barnes 12 Jun '04

12 Jun '04

I have recently switched from the UW imap server to dovecot and things seem to be working nicely. One thing that I can't seem to figure out however, is how to get dovecot to show folders that are a softlink. We run SpamAssassin. Users can use both their own personal spam folder as well as a shared spam folder. For messages that everyone would consider spam, the user can simply drag the message to the shared spam folder (messages that are only "spam to them" would go into their own spam folder). sa-learn is then run nightly for each user against both the shared spam folder and their personal spam folder. The shared spam folder is simply a file that everyone has rwx access to and is softlinked to ~/mail/SharedSpam. This used to work fine with UW imap because it didn't seem to care that this was a softlink. However, apparently Dovecot DOES care because when the user resets their folder list and the user selects the folder and chooses "show", they get the error message: Could not show "SharedSpam". The server refused to show it. The folder might already be shown. I have tried editing the .subscriptions file by hand and it does cause the folder to show up, but when the user trys to use it, they get the same error. Is there a setting somewhere I'm missing? -- + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + Chris Barnes AOL IM: CNBarnes chris-barnes(a)tamu.edu Yahoo IM: chrisnbarnes Computer Systems Manager ph: 979-845-7801 Department of Physics fax: 979-845-2590 Texas A&M University

[Dovecot] some messages showing up twice
by alan premselaar 12 Jun '04

12 Jun '04

I've recently installed dovecot 0.99.10.5 on a redhat 7.3 machine. Everything seems to be running fine and smoothly for the most part, however in the past few days I've seen a couple of duplicate emails (and so have a few of my users) which don't appear to have been processed twice by sendmail. also, on one of my IMAP sub-folders my mail client (mozilla thunderbird version 0.6+ (20040610) nightly) reported 1 unread email, but it didn't show up in the list. it appears that the index for that subfolder got corrupted (i moved all the .index* files to a backup directory and when i checked that folder, it recreated the index files and then showed me the one unread email) I realize that i'm using a nightly build of a beta mail client, but some of my users reporting similar troubles are using Mail.app and other clients. does anybody have any suggestions as to what I might do to get some useful debug info and/or find the cause of this problem? thanks, alan

[Dovecot] 'append aborted'
by Tom Allison 12 Jun '04

12 Jun '04

I'm copying all my archives from one imap server on one machine to the imap-ssl dovecot server on another machine. After a bit, there's an error that's tossed up on my mozilla client that says the imap server couldn't complete the operation with the message append aborted. It keeps popping up after anything from 50 to 300 emails. Last night I was able to move ~12000 emails from one machine to the other without the ssl enabled. Any hints on what to look for?

How can I secure dovecot listening on port 143 to specific machines only? Squirrelmail suggests using non-ssl if the imap daemon is on the same host... Otherwise squirrelmail could use TLS but what about other clients wanting to use SSL on port 993? (sorry I don't know enough about TLS).

[Dovecot] auth failure
by Tom Allison 11 Jun '04

well, with some help I've made a fair amount of progress on my box. It's working out much easier than I had anticipated and perhaps my notes will be useful some day. I have two questions... Here is where I am: cling:~# egrep -v "^($|\#)" /etc/dovecot.conf protocols = imap imaps login = imap login_max_processes_count = 16 login = pop3 max_mail_processes = 512 verbose_proctitle = yes default_mail_env = maildir:~/Maildir mailbox_check_interval = 1 auth = default auth_mechanisms = plain auth_passdb = pgsql /etc/dovecot-pgsql.conf auth_user = root auth_verbose = yes cling:~# egrep -v "^($|\#)" /etc/dovecot-pgsql.conf connect = dbname=dbmail user=dbmail_reader password=SECRET default_pass_scheme = PLAIN-MD5 password_query = SELECT passwd AS password FROM users WHERE userid = '%u' I've created working passwords using 'mkpasswd --hash=md5' and plugged the results into my database. I can login and everything looks pretty cool. Except, as near as I can tell, I'm sending plaintext authentication over the wire. My best guess is that my password gets munged into digest-md5 format before it goes over the wire. At this point I'm of the opinion that I'm reasonably secure. True so far? My guess is that the next step in security is to go for imaps and ssl configuration. But my debian installation doesn't appear to have the dovecot-openssl.cnf file referenced in the configuration.txt file. Is this missing from dovecot or am I looking at a debian problem?

[Dovecot] Corrupted index file
by Niilo Kajander 11 Jun '04

11 Jun '04

Hi, I've been wondering for a while if reiserfs is dovecot+maildir safe or not. I get this too often (and my imap session gets disconnected): Jun 9 08:42:32 sun imap(nk): Corrupted index file /home/nk/Maildir/.INBOX/.imap .index: UIDVALIDITY changed in uidlist This happens always when a new mail arrives in maildir. It's a Fedora Core 2 box running dovecot-0.99.10.4-4 (redhat) package. Could the reason for these corruptions be something else than reiserfs? I know there has been some problems with Fedora+dovecot but I haven't seen this one reported here. TIA, -- Niilo Kajander <nk(a)kajander.fi>

[Dovecot] bleah
by Tom Allison 11 Jun '04

11 Jun '04

Not to be a bitch, but I've asked several times about some basic questions or examples to clarify the essentials for configuration. What do some of the parameters mean? Expecially the ones that are mentioned only one in a paragraph and no where else in the documentation or wiki. (ie: login_process_per_use) And there have been a few others as well. that I won't bother to repeat. But I've been sitting on this list for a while yet and have found that when it comes to configuration, none of the emails posted have been answered or addressed. The closest I got was a suggestion to use views instead of tables in postgres. But technically nothing was ever said about dovecot itself. So I have to ask. Is the sketchy documentation in the source file, the web page, wiki, and limited reponse on the mailing list a matter of "I haven't gotten around to it yet" or a deliberate move to promote the commercial support potential for Procontrol? I've run into this kind of environment twice before (cyrus and razor) and in the case of cyrus they just didn't believe in doing the documentation but suggested I write it myself. That may be the case there as well ("I haven't gotten around to it yet". That's OK but cyrus has the difficulty of no one still not providing any answers to how anything was done, configured, functioned, or why. So documentation was kind of a reverse-engineering project in itself. In the case of razor it's a mix of no time and they would rather support the company than the project. I went back and re-read the emails that I had posted earlier and am pretty sure that they weren't too stupid (ie: how do I test an imap connection), difficult, or obscure (well, maybe one). I'm just trying to find more information on how to correctly configure this server such that I can retain the concept of keeping security in mind. I'm trolling through the archives and there doesn't seem to be much discussion from anyone else. So maybe I'm really stupid and can't do authentication schemes. I'm sure by this point I've really pissed a few people off and for that I mostly apologize. I'm a little bent here myself. It just that I didn't plan on having to set up sniffit to track my IMAP traffic in order to verify that things were actually working securely. I'm going to plug along and do it myself and probably get something to work. I have plain_text authentication working now, but was really hoping to actually get something secure. At this point I really don't expect an answer, but do hope that after 1.0 is released there will be time available to get some documentation in order. IMHO the level of documentation that is available on a software project is critical to it's use.

[Dovecot] "virgin" mail accounts
by Christian Balzer 11 Jun '04

11 Jun '04

Hello, I'm willing to swear that with the 0.99.10.4 Debian package in my rather extensive tests with mailbox format dovecot created not only any missing parental directories but also the INBOX file, but the later I can't prove/test now as I upgraded all respective boxes. However 0.99.10.5 will still create (if needed and possible) missing directories for mbox storage, just not an empty INBOX. But with maildir, it will not even do that, from a test with pop3 and imap login attempts to a freshly created account that had not received any mails yet: --- Jun 10 12:58:03 mb01 pop3-login: Login: test [203.216.5.92] Jun 10 12:58:03 mb01 pop3: I/O leak: 0x8050ce0 (0) Jun 10 12:58:03 mb01 pop3: I/O leak: 0x8084aa0 (1) Jun 10 12:58:49 mb01 imap-login: Login: ttest [203.216.5.92] Jun 10 12:58:50 mb01 last message repeated 3 times Jun 10 12:58:50 mb01 dovecot: child 9193 (imap) killed with signal 11 --- It died not very graceful in either case, esp. the later. Unless there are very RFC'ish and imperative reasons, I'd suggest that dovecot creates all missing bits if possible no matter what the storage method or pretends to have encountered an empty mbox file or maildir cur/new respectively. The rationale should be obvious, no frantic user calls about "My mail is not working" when the answer is "Duh, that's because you never ever received one yet". ;) Regards, Christian Balzer -- Christian Balzer Network/Systems Engineer NOC chibi(a)gol.com Global OnLine Japan/Fusion Network Services http://www.gol.com/

[Dovecot] 2 problems
by Cor Bosman 10 Jun '04

10 Jun '04

Hi all, im testing dovecot as a replacement imap server and noticed 2 problems in 0.99.10.5. if you use dovecot/pop on an account who's quota is fully used, dovecot will ungracefully stop. This will only happen when the account is first accessed by dovecot (for instance, when offering IMAP to an existing userbase using dovecot, or when the index files have inadvertently been deleted). +OK dovecot ready. user scorpio +OK pass xxxxxxxx +OK Logged in. Connection closed by foreign host. The same goes for imap: * OK dovecot ready. . login "scorpio" "xxxxxxx" . OK Logged in. . select INBOX . NO Out of disk space This is a bit of a problem because one of the remedies of solving an out of disk space problem is deleting email, which you cant now. Cor

[Dovecot] authentication configuration
by Tom Allison 10 Jun '04

10 Jun '04

I've included the non-defaulted bits of my dovecot.conf file at the bottom of this email. As I understand my set-up it's using unix authentication methods (/etc/passwd via pam?). Considering disable_plaintext_auth and auth_mechanisms, what exactly is being passed? I was hoping to get auth_mechanism = digest-md5 but that's not working out very well right now. It seems I can only do plaintext authentication. I got stuck on the userdb/auth_passdb settings. Can someone give me an example of how to configure for md5-digest authentication? My current guess is: disable_plaintext_auth = yes auth = digest-md5 auth_mechanism = digest_md5 auth_passdb = /etc/mydigestfile How would I set this for pgsql? auth_passdb = /etc/dovecot-pgsql.conf ### non-default config settings. protocols = imap imaps disable_plaintext_auth = yes login = imap login_max_processes_count = 16 login = pop3 max_mail_processes = 512 default_mail_env = maildir:~/Maildir mailbox_check_interval = 1 auth = default auth_mechanisms = plain auth_passdb = pam auth_user = root

[Dovecot] configuration
by Tom Allison 10 Jun '04

10 Jun '04

I've noticed that there are some parameters mentioned in the docs that aren't identified therein (ie: login_process_per_use). Is there a more generic set of docs that can identify what each of the parameters and what they do, or at least something that will allow me a simple how to to avoid embarrasing situations. I supposed I should only settle for ssl based connections (imaps/pops) but I will be open to digest-md5 if I could. I'm also curious to see how I can use pgsql authentication with dovecot. I think this would be great to work with since I'm basing all my postfix settings around postgresql as well. But for now I'm not sure how to use postfix authentication with the file directories I'll need to use for the maildirs (and procmail!).

[Dovecot] pgsql configuration
by Tom Allison 10 Jun '04

10 Jun '04

from the pgsql configuration file: # Query to retrieve the password. # # The query should return one row, one column. If more than one row or column # is returned, authentication will automatically fail. # # Available substitutions: # %u = entire userid # %n = user part of user@domain # %d = domain part of user@domain # # Query to retrieve the user information. # # The query must return only one row. The columns to return are: # home - Home directory # mail - MAIL environment # system_user - System user name (for getting user's groups from /etc/group) # uid - System UID # gid - System GID # # Either home or mail is required. uid and gid are required. If more than one # row is returned or there's missing fields, login will automatically fail. # I'm a bit slow here, so if someone could just nod if I'm in the right direction: I want to support IMAP for at least two domains. Therefore I have to use the authentication string of: SELECT password FROM users WHERE userid = '%u' and the user must enter their entire email address for their login name. (I can do this!) I want some portion of these domains and users to be consistent with existing accounts in my /etc/passwd database. I don't expect to use passwd information for the username and password, but I want the information returned for joe(a)domain2.com to be for the user:joe in my passwd file and have his email in /home/joe/Maildir. Similarly, I want others (either fred(a)domain2.com or jane(a)domain1.com) to be (ideally) all driven under a non-local account name and login. For this second one, I'm thinking I need to do something like this in the user information query (this is mostly a guess): for joe(a)domain2.com (/etc/passwd) :: jane(a)domain1.com (no passwd) home - /home/joe --or-- can I use ~/ :: /var/spool/imap/%d/%n ?? mail - maildir:~/Maildir :: maildir:/var/spool/imap/%d/%n ?? system_user - joe :: (a guess -- adduser dovecot-imap to passwd maybe) uid - joes uid (1002) :: dovecot-imap uid (510) gid - joes gid (1001) :: dovecot-imap gid (510) with seperate group This is where I get fuzzy. If someone could help me figure out where I went wrong I would appreciate it. If I did this correctly, then in theory I could pass email delivery to procmail and have one set of rules (/etc/procmail) do some additional filtering for all the email under my domain1.com (spam filtering mostly) and perform a final delivery to maildirs in /var/spool/imap/doamin1.com/jane/ Or am I sleep deprived?

[Dovecot] dovecot newbie question about "invalid key" problem
by Joakim Verona 10 Jun '04

10 Jun '04

Hello list, I've trying to migrate a small uw-imap server to dovecot. It works somewhat, and speed seems greatly improved, so thats great. However, I get an "invalid key/Internal Error" problem when connectiong to my INBOX with thunderbird. According to google this is a well known problem with mozilla mailers. Dovecot is not lenient with this bug in thunderbird. Is there some workaround for this? I noticed that its possible to turn on some client bug workarounds for outlook. Does the same go for mozilla? I tried one described remedy, which was to delete the account information and re-register the account. This didnt help. The problem seems to be only with INBOX, which I have mapped to /var/spool/mail/<username>, not my other imap mailboxes. Im running gnus as well and the problem doesnt seem to occur there. My configuration: Redhat 9 dovecot 0.99.10.5 (from DAG repository RPM:s) Another question: Would it be possible to run uw-imap on one port, and dovecot on another? Or would that corrupt the mailstores? Regards, /Joakim

[Dovecot] Feature request?
by Stephen K. Gielda 10 Jun '04

10 Jun '04

I'd like to toss a feature request on the table for consideration. We currently use a different popd because of a feature that allows us to restrict pop access based upon an allowed users list. This is the only thing that keeps us from using the popd in dovecot currently. It's a simple text file of usernames that are allowed to use pop, if the name isn't in that list then pop access is denied. Is this something that can be considered for a future feature addition? Would anyone else also find this useful? /steve

[Dovecot] Help: RH9 upgrade (mbox)
by Guy Davis 09 Jun '04

09 Jun '04

I just upgraded my RH9 server with UW-IMAP to Fedora Core 2 and after a short try with Cyrus, I'm hoping to get Dovecot configured. My problem is getting Dovecot to recognize my old mbox mail folders. It correctly shows the INBOX contents from the /var/spool/mail/davis mbox. However, I also had a bunch of mboxes such as: /home/davis/Mail/Sent /home/davis/Mail/Lists/list1 Reading the documentation, Dovecot indicates it will recognize mbox files within the ~/mail directory. So I moved my mail over giving: /home/davis/mail/Sent /home/davis/mail/Lists/list1 Unfortunately, after restarting Dovecot and restarting my IMAP client (Mozilla), I don't see anything other than my Inbox. If I create a file (/home/davis/mail/.subscriptions) with 'Sent' in it, and restart things then I can see Inbox and Sent. This would let me have a single directory with multiple mbox files in it. However, I'm not able to get Dovecot to recurse and let me see mboxes in subfolders such as: /home/davis/mail/Lists/list1 As well, when I first connect to Dovecot via Mozilla, I get an error saying: 'The current command did not succeed. The mail server replied "Invalid mask"'. What does this mean and how do I correct it? Any help would be greatly appreciated. Thanks, Guy

[Dovecot] mta/mda config
by Jure Pecar 04 Jun '04

04 Jun '04

Hi all, I'm at the stage of planning our new mail system and am evaluating dovecot for it. For large mailstore setups, it makes sense to split maildirs across many directories. I see that setting default_mail_env to something like maildir:/var/imap/domain/%1d/%d/%1u/user/%u/ would create almost identical on-disk layout as multidomain cyrus setup. Now, as dovecot does not have its own mda or lmtp daemon, how does one configure mta (eg. postfix) to deliver mail in such maildirs? Related question ... any cyrus to dovecot migration tales? :) -- Jure Pečar

[Dovecot] Advice on converting from Mbox to Maildir?
by Villalovos, John L 04 Jun '04

04 Jun '04

Does anyone have advice or pointers on good documentation on how to convert a system from using the Mbox format to using Maildir? I recently upgraded to Fedora Core 2 from Fedora Core 1 and discovered that UW-IMAP was gone. So I switched over to using Dovecot. So far so good. But I would like to convert my system to start using the Maildir format. How easy is this to accomplish? Can I keep my Inbox /var/spool/mail/user_name as an mbox format and have my other folders as Maildir? What would I have to change for Sendmail to make it use Maildir for the Inbox? Can procmail support Maildir? Any pointers or help would be much appreciated? John

I am using dovecot-0.99.10.5-1 which was on the development tree of Fedora. Though I would think the one that came stock with Fedora 2 should work as well. I have no reason to think it won't. One note. I don't use POP that much. I have one person who uses it and they haven't complained. > So if all the mail is moved to Maildir (thus eliminating the typical > mailspool), and somebody pop's onto the server, Dovecot will use the > Maildir/Inbox for the pop? Yes it will. If you read the mail-storages.txt documentation file it talks about it. I would read the section on "Detecting what to use". I did NOT set the default_mail_env variable in my /etc/dovecot.conf and it figured it out automagically :) Good luck, John

[Dovecot] 0.99.10.5 imap flag update issues

Hi, there is an issue left in 0.99.10.5 which (I think) is a problem with imap status flags. It shows up in two places: (1) When new mail is delivered to the inbox, the last read mail changes to "unread". (2) When you move mails from the inbox to another folder with Mozilla (1.6 on win32, Linux, NetBSD), they are not removed from the inbox, effectively performing a copy instead of a move. And, while I am at it, (3) I see a regular log entry from a MS Outlook 2000 SP 3 Jun 3 10:26:23 bounce imap-login: SSL_read() syscall failed: EOF [130.83.XXX.XXX] The setup here: OS NetBSD 2.0beta, MTA sendmail 8.12.11, LDA maildrop 1.3.9, dovecot 0.99.10.5, OpenSSL 0.9.7d Any ideas? hauke -- Hauke Fath /~\ The ASCII Ribbon Campaign Institut für Nachrichtentechnik \ / No HTML/RTF in email TU Darmstadt X No Word docs in email Ruf +49-6151-16-3281 / \ Respect for open standards

[Dovecot] Getting POP3 up and running

Hi! Now that I happily smiling have Squirrelmail working on the new setup (Fedora Core 2), the next hurdle seems to be getting POP3 to work. According to my understanding of the documentation I changed the protocols line in dovecot.conf to: #protocols = imap imaps pop3 pop3s then restarted dovecot, but still can't connect to pop3 (not even after rebooting the whole system). Doing an nmap on my server does not show port 110 as open. Any clues as to what I may be overlooking?

[Dovecot] Loggin error with Squirrelmail on Fedore Core 2
by Antonio Nunes 03 Jun '04

03 Jun '04

Hi! I am switching a mail server setup to a new machine which has RHL Fedore Core 2 installed, which uses Dovecot. I managed to get Squirrelmail to work on my personal account, but when logging in with some other accounts I get the following error as response: ERROR : Connection dropped by imap-server. Query: Capability I did a web search on this and found a message from Tim Middleton who experienced the same problem. He also suggests a workaround: "I put in a chron job to touch into existance any non-existing mailboxes for everyone in the passwd file periodically, which mostly eliminates the problem. But I'd still like to know why the server is having the problem, if anyone can make any suggestions." I would like to try this, but I am still fairly new to Unix. Could anyone show me how to set up such a chron job? Are there other, manual, ways to touch the mailboxes? Thanks, Antonio Nunes Don't let who you can be keep you from being who you already are.

[Dovecot] Supporting POP & IMAP with Sendmail
by John Duino 03 Jun '04

03 Jun '04

Greetings! I dug thru the archives but didn't see a clear answer to this. A client has an existing sendmail/pop3 system, and I would like to switch to dovecot for imap support. For imap I much prefer the Maildir format over mbox, however, sendmail natively dumps to mbox (mailspool) and that is what pop typically reads. I've read the threads on how to make sendmail write to Maildir. My problem is that I'd like to support both pop/mailspool and imap/maildir. While running dovecot in imap-only it will use mbox format to read the /var/mail/user as the Inbox and then create the full imap structure under ~user/mail but in mbox format, not maildir. If/when I turn on both pop and imap in dovecot will it allow this with the current config? Or will I still need to convert sendmail output to maildir...and then I assume dovecot/pop will read from ~user/Maildir/Inbox even though it is in Maildir format? Basically, if I'd prefer to not have to convert sendmail to Maildir format, have dovecot always treat /var/mail/user as the Inbox for both pop and imap, and for those who switch to imap, have it store their other folders in ~user/Maildir. Asking too much? Thanks! John

Timo says that it is NOT available in the version that comes with Fedora Core 2. It will be available in the 1.0 series by defining multiple namespaces. The current 1.0-tests allow this. > What would I have to change for Sendmail to make it use > Maildir for the Inbox? Sendmail does NOT need to be changed. > Can procmail support Maildir? Yes and that is what you need to change. I setup /etc/procmailrc to have the line: DEFAULT=$HOME/Maildir/ Make sure there is the terminating / on that line. What this will do is make all new mail that is delivered via procmail go to each user's Maildir folder. But what you need to do first is convert your existing mbox mail into maildir format. I used the program that was recommended to me: mb2md http://batleth.sapienti-sat.org/projects/mb2md/ This program worked great to convert my /var/spool/mail/user_name stuff and also folders that I had created under ~/mail/ So now my whole system is using Maildir format.

[Dovecot] dovecot and virtual hosting
by Vegard Svanberg 03 Jun '04

Hi. A usual hosting provider setup depends on having one IP ("virtual mailserver") per domain. Using dovecot on servers handling hundreds or thousands of domains today equals to having multiple instances of dovecot running. This problem could be solved by making dovecot take into account the IP address the user connects to and authenticate against the proper {database, table, pw-file, [...]} based on that.

Has anyone considered setting up a Dovecot public server to serve the list archives by IMAP? Or does Dovecot not do anonymous read-only access? (I note by comparison that the Cyrusoft Mulberry list archives are served by an IMAP server. <http://www.cyrusoft.com/mulberry/support/anonimap.html>) It should be sufficient to set up Dovecot on some server in the dovecot.org domain and subscribe it to the lists.

[Dovecot] Dovecot + SSL + Fedora
by David Keegel 02 Jun '04

02 Jun '04

I've been seeing the Dovecot/SSL/Fedora 1 problem. I have a dovecot server which tends to die at least once a day, with messages like these :- May 24 13:44:44 mail pop3-login: RAND_bytes() failed: error:24064064:random number generator:SSLEAY_RAND_BYTES:PRNG not seeded May 24 13:44:44 mail dovecot: Login process died too early - shutting down I noticed Timo's email about this at: http://www.dovecot.org/list/dovecot/2004-May/003316.html with the patch that just ignores the return code of RAND_bytes(). Would disabling SSL in dovecot.conf also be a reasonable way of avoiding the problem of dovecot crashing? My plan is to set ssl_disable = yes and also take out pops and imaps from protocols. That is a lot easier for me than getting source, patching it, re-compiling and re-installing. We are using Fedora Core 1 (fedora-release-1-3 i386 rpm) Dovecot 0.99.10 (dovecot-0.99.10-4 i386 rpm) OpenSSL 0.9.7a (openssl-0.9.7a-33.10 i386 rpm) ___________________________________________________________________________ David Keegel <djk(a)cybersource.com.au> http://www.cyber.com.au/users/djk/ Cybersource P/L: Linux/Unix Systems Administration Consulting/Contracting

[Dovecot] 0.99.10.5 release candidate
by Timo Sirainen 02 Jun '04

02 Jun '04

http://dovecot.org/rc/ Thought I'd still make one 0.99.10.x release now that mbox corruption problems are (hopefully) fixed. Please test, if no problems are found this will be the final 0.99.10.5. Changes since .4: + MySQL authentication, patch by Matthew Reimer - mbox: APPEND reversed given \Draft and \Deleted flags - mbox: "LF not found" errors happened sometimes when X-IMAPbase header was updated. Possibly corrupted mbox sometimes. Thanks to Fabrice Bellet for finding this bug. - Custom flags couldn't be unset - Maildir: make sure ":2," is appended to filename when moving mails from new/ to cur/.

[Dovecot] Postfix SASL AUTH from Dovecot
by Timo Sirainen 02 Jun '04

02 Jun '04

Again today got annoyed at Cyrus SASL. Upgrading it to newer version had broken PAM support. Trying to login as "user@domain" resulted it only asking for "user" from PAM. Well, got it patched and working again, but I'd rather not go through it all the time.. So I finally did what I had been thinking about a year or so, change Postfix to use dovecot-auth directly. This required cleaning dovecot-auth quite a lot, but it seems to be working now. Actually I finally implemented support for initial SASL response as well. POP3's AUTH command had required support for it, strange that no-one ever complained about it not working. If you want to try it, you need very latest CVS version of Dovecot and this patch for Postfix: http://dovecot.org/patches/postfix-dovecot-auth.patch dovecot-auth can be run on it's own (configuration in environment variables), or you can use extra_sockets auth setting which is a ':' separated list of UNIX sockets where to listen in. You'd probably want to set it to /var/spool/postfix/etc/dovecot-auth, the location is hardcoded to /etc/dovecot-auth in the patch for now (smtpd is chrooted). The only real problem is that Dovecot creates the dovecot-auth socket using 0660 root:root modes, so you have to manually chmod it to 0666 or fix owner/group. I guess that needs some more thinking.. Probably each socket should have separate settings for it, but how to do it easily in configuration? .. The patch has also hardcoded dovecot path in Makefile.in, you'll need to change that.

[Dovecot] IMAP login name conversion
by Zoong Pham 01 Jun '04

01 Jun '04

Hi all, Out IMAP client (Outlook and others) use login name like joedirt(a)domainname.com I need dovecot to convert it to joedirt-domainname_com since that is the local login name. Can someone give me a hint how to do that? Is there any simple way to do it or do I have to modify any source code? Thanks, Zoong

[Dovecot] 1.0-test14: no sendfile() in Solaris 8
by Andreas Jaekel 01 Jun '04

01 Jun '04

Aloha. The current CVS snapshot and 1.0-test14 will not build on Solaris 8 because it does not provide a sendfile() funtion. It just has sendfilev(). Solaris 9 has sendfile(), though. Using the old sendfile-util.c from 1.0-test1 and setting HAVE_SOLARIS_SENDFILEV instead of HAVE_LINUX_SENDFILE in config.h works. Greetings, Andy.

[Dovecot] Small change to make dovecot pop3 uw-imap migration friendly
by Oleg I. Vdovikin 01 Jun '04

01 Jun '04

Hi, today I've finished migration from uw-imap daemons to shiny and fast dovecot. With thanks of dovecot my mail server load average drops by factor of ten even with ancient unix mailboxes. ;-) So, the only thing I've discovered is what POP3 uidls are different than ones used in the uw-imap. Luckily, the difference are only in the format string used in uidl response. So, I've made the following change in the code --- dovecot-0.99.10.4.orig/src/pop3/commands.c 2003-05-28 15:17:15.000000000 +0400 +++ dovecot-0.99.10.4/src/pop3/commands.c 2004-05-27 14:06:48.000000000 +0400 @@ -374,7 +374,7 @@ while ((mail = client->mailbox->fetch_next(ctx)) != NULL) { client_send_line(client, message == 0 ? - "%u %u.%u" : "+OK %u %u.%u", + "%u %08x%08x" : "+OK %u %08x%08x", mail->seq, client->uidvalidity, mail->uid); found = TRUE; } and got everything just like in the old uw-imap pop3. I'm current running RH9, but thinking of FC2 which uses dovecot. So, I've rebuild the FC2 rpm for RH9 including this patch. Pop3 users, which do not remove their mails from the server are really happy - they do not receive old mails twice. Probably this small change could be applied to the 1.0, or used as a config option. Any suggestions are greatly appriciated. Thanks, Oleg.

[Dovecot] 1.0-test14
by Timo Sirainen 31 May '04

31 May '04

http://dovecot.org/test/ Maildir syncing is still somewhat broken. I can't really figure out what the problem is. Maybe it's in indexes after all which are just causing bugs in syncing. I think I'll finish implementing mbox syncing and see if same problems appear with it. This release has mostly dovecot-auth changes: - Delay reporting failed authentications - Log IP address of failed authentications (if verbose = yes) - Password schemes can now be loaded from plugins. Example: http://dovecot.org/patches/1.0/password-scheme-lmpass.c - (now that I think of it, auth mechanisms could be implemented as plugins as well if they were placed in password-scheme directory, I think I'll change the directory name so it's more logical) - SASL initial responses are supported (POP3) - SHA/SHA1 password scheme implemented with OpenSSL - dovecot-auth can run as standalone process now (but that doesn't work with Dovecot itself at least yet) - Changes to make it more easier to use it outside Dovecot (eg. the Postfix patch) Added new variables which can be used: %l - local IP address %r - remote IP address %P - PID Added mail_log_prefix setting where variables can be used. So if you want eg. "imap(user,ip-addr,pid): ", set it to "%p(%u,%r,%P): ". And others: - added maildir_stat_dirs setting - several bugfixes for indexes

[Dovecot] Dovecot returns everything starting with "." as folder
by Christoph Hohmann 30 May '04

30 May '04

Hi, I'm using dovecot imapd 0.99.10.5 from debian unstable and I noticed that dovecot returns everything in the maildir folder that starts with a "." as a folder as the result of LIST "" "%" command without checking if it is really a maildir folder (must contain the directories cur, new, tmp and the file maildirfolder). This is a little bit annoying because it also returns Sylpheed's cache files '.sylpheed_cache' and '.sylpheed_mark' if they exist in the maildir. -- http://reboot.animeirc.de http://sylpheed-claws.sourceforge.net/

[Dovecot] dovecot API / Virtual Folders?
by James Moser 30 May '04

30 May '04

I was wondering if anyone has done something like this, or knows of any reason it would not work. Would it be possible to use dovecot's API to create virtual folders where when messages are placed in them some other application can be executed on them? With programs like DSPAM and SpamAssassin, and with users who do not have shell access to the machines, it would be nice if there was a way they could do something like this to use dspam/sa-learn, that way they could use it with any mail application. I don't like the idea of using cron to do this. -- James L Moser james(a)powweb.com PowWeb Hosting http://www.powweb.com /(bb|[^b]{2})/, that is the Question. mysql>SELECT * FROM user WHERE clue > 0; Empty set (0.03 sec) Health is merely the slowest possible rate at which one can die...

[Dovecot] dovecot and nfs
by Dan Stromberg 30 May '04

30 May '04

I configured dovecot on a Fedora Core 2 system - the version that comes with FC2. I was using it with a RHEL 3 NFS server. Dovecot would again and again get stuck trying to grab an fcntl lock, even though I specified that it should only use dotlocks in dovecot.conf. Sometimes it would segfault (leaving things locked?). Often there would be two dovecot imapd processes for the same user. I've since moved dovecot onto our internal NFS server, but we have many (relatively) external imap servers where it might be nice to use dovecot, and in a number of those scenarios, NFS would be a requirement. Thanks. -- Dan Stromberg DCS/NACS/UCI <strombrg(a)dcs.nac.uci.edu>

[Dovecot] Messages does not appear in OE6
by Mauricio Araya V. 29 May '04

29 May '04

Hi List! I have an issue with dovecot: Outlook express users sometimes can't see some emails (they are not even listed) that can be seen with other IMAP clients, I tested it (and it works) with Evolution, Outlook and SquirrelMail (a web mail). Please note that this is not the client bug reported at http://dovecot.org/clients.html with the message: "Message is no longer available on this server" I have the following configuration: - Postfix as MTA (ver. 2.1), using the Maildir format to store messages. - Dovecot 0.99.10.4_2 serving POP3 and IMAP. Relevant dovecot config: client_workarounds = oe6-fetch-no-newmail outlook-idle default_mail_env = maildir:/%h/Maildir Something important is that I am using freebsd 4.9, and dovecot is installed from ports (/usr/ports/mail/dovecot) Does anyone has the solution for this problem, or at least an idea of what causes it? Regards, -Mauricio

[Dovecot] IMAP views - and things to make Outlook Express not suck so much
by Geo Carncross 28 May '04

28 May '04

Some of the things that keep being brought up SEEM TO ME to be a form of IMAP crack that can be accomplished in a much more generalized manner with a little bit of thought. An idea I had a while back was for IMAP views. It accomplishes the four things I keep seeing on this list without being specific to any of them. Consider new configuration variables: rewrite Junk { folder = INBOX search = KEYWORD "Junk" post = +FLAGS (Junk) } rewrite Trash { folder = * search = DELETED fetch = -FLAGS (\Deleted) post = +FLAGS (\Deleted) } Views would not be deletable (unless one wants to invent some nonstandard IMAP extensions today), but they would otherwise look like regular folders. One could post and search and fetch messages as normal (with some alterations to various IMAP fields). In the examples I gave: A001 SELECT Junk A002 SEARCH ALL A003 SELECT Trash A004 SEARCH ALL A005 FETCH 1 FLAGS would be translated into: A001 SELECT INBOX A002 SEARCH ALL KEYWORD Junk A003 SELECT {for each SUBSCRIBED folder} A004 SEARCH ALL DELETED A005 FETCH 1 FLAGS Except, A005 would actually yield: * 1 FETCH (FLAGS ()) Instead of: * 1 FETCH (FLAGS (\Deleted)) It would probably be ideal if these were configurable per-user, but I'd be happy with system-wide rewriting. Options for rewrite could include: folder = folders that could be selected using LSUB OR a valid (existing) folder name. If this is system wide, pretty much only INBOX, INBOX.% and INBOX.* and * and % are valid :) search = tags to append to SEARCH operations on the view fetch = IMAP fields that are acceptable to STORE that we will pretend occurred when fetching. recent = IMAP fields that should be STORE'd when the \Recent flag is still set. post = IMAP fields that are acceptable to STORE that we will perform when APPENDing or STOREing. append = argument to be passed to /bin/sh -c which will receive on standard input the APPENDed body, and produce on output a STOREed body. open = argument for /bin/sh -c for when this view is SELECTed or EXAMINEd close = argument to be passed to /bin/sh -c for when the view is closed. index = argument to be passed to /bin/sh -c for when dovecot wants to index a portion of the message. standard input of the argument is the message, whereas standard output is the portion to actually index. path = a regular dovecot mailbox path that would contain the real contents of this folder. ro path = like path, but would be decidedly read-only (except for any side-effects generated by append =) Subprocesses that exit 99 would handle the task internally- thus any normal actions (such as for index = and append =) would not occur. Exit code 0 is for normal completion, and all other exit codes should generate an error. If one allowed open = and close = to be used on REAL folders, this would allow people to actually have the behavior UW-IMAP does by MOVING mail from /v/s/m into ~/mbox... One could use append = with a "Outbox" view that could write the queue at the same time as storing a copy into Sent Items. One could also use append for gpg-signing messages as they're being recorded. One could also use append for publishing to a mailing list. One could use index = to spell-check messages beforehand thus improving my chances of actually finding messages from my PHB. One could also use append =, recent = and ro path = to emulate shared folders support in a manner that would be useful for using IMAP folders as a kind of work-queue. Thoughts?

[Dovecot] dovecot immediately exits on Fedora 2
by Per Bothner 26 May '04

26 May '04

I "upgraded" my server running UW-IMAP on Fedora 1, to Fedora 2, which defaults to Dovecot. Unfortunately, the server refuses connecions from my client (Mozilla). It seems that Dovecot immediately exits: ps aux|grep dovecot shows nothing. Also, if I manually start up dovecot, it immediately exits, with no messages. (It does at least parse the config file, since tweaking that gives me errors.) What is surprising is that I haven't been able to "Google" to find anone else reporting someting similar, so I'm wonderring what makes my system unique. I tried downloading, compiling and running the current UW-imap. Mozilla is able to connect to it, and ask for a password, but rejects the login. Curious that we're getting two such very different failure modes. Help would be most appreciated; for now neither I nor others who use my imap server can access our mail (except by directly viewing the /var/spool/mail file). -- --Per Bothner per(a)bothner.com http://per.bothner.com/

[Dovecot] feature request: undeletable folders
by Marten Lehmann 26 May '04

26 May '04

Hello, as we all know from the big webmail-services like hotmail.com, yahoo.com, web.de and so on, several folders exist and nobody can remove them for a good reason, because some services rely on them: Trash, Junk, Sent. Can can't remove Trash, because every deleted message is just moved here. You can't remove Junk, because all messages recognized as spam is moved here. And you can't remove Sent, because all messages you sent through the webmail are saved here. With the common courier-imap, everyone either has to bloat his webmail client with permanent checking if the required folders exist and recreate them if needed, or he has to patch courier-imap each time a new release appears to extend to this certain functionality. So why not just include this feature in courier-imap generally? I think there's no need to handle these folders on a per mailbox basis. Courier-imap could look at a file that contains the unremovable folders (one per line) and deny deletion of this folders. Now you might say: "You could prevent deletion of this folders in your webmail client as well." But that's only the half of the truth, because if you just want to see webmail as one option of accessing the emails, but POP3 and IMAP access is offered as well, then deletion must be restricted at IMAP side. I didn't implement this feature yet, but I'll need it in near future, so either someone else implements it our I would send you a patch after I implemented it. Regards Marten Lehmann
