Timo, a very simple save-only LDA would be enough for many configurations. Other full featured LDAs such as procmail could also use dovecot-LDA as the final delivering program. This would keep gigantic mboxes always indexed, and make access on them snappy always, especially on the important first access. However this should not take many programming resources away from releasing a robust, migration-ready v1.0. I am eager to migrate 25,000 users (~100GB), onto dovecot and then provide them more disk space, which now I dare not allow them. Keep up the excelent work! apap > Date: Mon, 9 Aug 2004 02:03:53 +0300 > From: Timo Sirainen <tss(a)iki.fi> > Subject: Re: [Dovecot] Dovecot Local Delivery Agent > To: Dovecot mailing list <dovecot(a)dovecot.org> > ... > Anyway, I'm still hoping someone else to do the LDA so I don't have to > worry about it.

[Dovecot] Little problem with dovecot using mbox format
by Jd 09 Aug '04

09 Aug '04

Hi everyone, this is my first post on this mailing list. I recently installed postfix+dovecot+fetchmail on OpenBSD for my dad's office. (dovecot is setup as an imap server using mbox). Everything worked flawlessly...until now. I don't know why, but now some emails seem to de-double themselves. For exemple, yesterday morning I printed out all the emails. To my surprise 30 minutes later, I received 60 'new'' emails. But these 60 emails weren't new, they were all copies of emails I had printed out earlier. Some emails were repeated some 10-15 times. Now we never got this kind of problem until recently. Has anyone ever experienced this kind of problem? If so how did you fix the situation? Most responses I got from the openBSD mailing list was to use maildir format. Any insight into this? Thanks, Jean-Daniel BTW we don't get THAT much email, maybe 200 a day for that 1 account that seems to be acting weird now.

My current goal is to make it mature enough and good enough where people might actually want to do that -- as I say, by finishing up some of the things that are still undone. Also there are a couple of things that are hardwired to the environment here (particularly, the way that the IP addresses are extracted for DNSBL tests), that I felt that I should make more general before making it open. The latest sources are available online to anybody who wants them, for use in your own environment, for experimentation and trial, but not for redistribution; but indeed if there was some demand I would probably open it up sooner than later. So far nobody has been beating down the door for it (admittedly I haven't really mentioned it in very many places; I think only here and on the bsdi-users list). But yeah, the plan is to make it so that you can modify it and redistribute it. I don't have any kind of hard and fast position on when, though. I'm sure most anyone could convince me to open it up most any time, if there was good reason to do so. mm

[Dovecot] search functionality
by Cor Bosman 06 Aug '04

06 Aug '04

Hi all, if I give the following command in test32: A004 UID SEARCH CHARSET ISO-8859-1 ALL TEXT {4} Test The response is: * SEARCH A004 OK Search completed. If I say: A004 UID SEARCH CHARSET ISO-8859-1 ALL FROM {4} Test The response is: * SEARCH 217 350 A004 OK Search completed. The RFC says that 'TEXT' is supposed to result in a list of messages where the search string is in either the body or the header. Obviously the string is there in this example, else the FROM search wouldnt have given a result. Tracing the process shows that dovecot never actually checks the email messages for the string. It does for a BODY search but not for a TEXT search. Is this on purpose? Cor

Hi, I am trying this way(mailinglist), as I cant find good 'support'/howto/tutorials on the website. I am running Fedora Core II, using postfix with mysql, and I want to use dovecot as imap server. Now I installed Dovecot using dag wieers SRPM, I compiled it with mysql, pgsql; %configure \ --with-ssl="openssl" \ --with-ssldir="%{_datadir}/ssl" \ --with-ldap \ --with-pgsql \ --with-mysql \ --with-cyrus-sasl2 \ --with-rawlog %{__make} %{?_smp_mflags} After compiling it, I installed the rpm.

[Dovecot] Dovecot Courier
by Michael Baird 06 Aug '04

06 Aug '04

Hello, I've been testing dovecot, and it appears to be much faster then courier-imap. I am using the latest .99 version, trying to make the transition from courier to dovecot as smooth as possible. We really only use IMAP via squirrelmail, I think I've got that worked out fine, changing a few settings in squirrelmail as the FAQ instructs and migrating the courier subscriptions to .subscriptions. I've noticed the folders .Trash .Sent are no longer subfolders of the INBOX,, and when I create new folders in a Client, it creates .INBOX.foldername, and a .INBOX. I would really like all folders to be subfolders of .INBOX, I've set dovecot up as the following. default_mail_env = maildir:/var/export/%h/.maildir:INDEX=/var/indexes/%n I've also tried putting the INBOX:/var/export/%h/.maildir in there as well with no luck. I essentially want .INBOX to be .maildir, and any subfolders would be called .Sent or .Trash or whatever, like in courier, is this possible? Regards MIKE

[Dovecot] Adding mail to dovecot directories
by Chris Dean 03 Aug '04

03 Aug '04

I run mailagent (which is similar to procmail) to filter all my incoming messages. I would like mailagent to put these messages directly into my dovecot server. What I'm doing right now is to create files (one per message) in the "~/mail/.folder-name/new" directory, or in the case of INBOX, in the "~/.mail/new" directory. I have ~/.mail as my maildir. The files created have MH style names: "1", "2", etc. and the names are often reused throughout the day. That is, the file named "1" might be created dozens of times per day with new contents. Is this the right way? Regards, Chris Dean

Re: [Dovecot] SSL CA root certificate
by Mail Admin 03 Aug '04

Problem solved. In my case I was using the 0.99.10.x release of dovecot, which does not recognize the ssl_ca_file directive. Upgrading to 1.0-test32 was step one. The next step was finding the right format for DST's root certificate. I think the format that finally worked was the format DST distributes for Apache Raven. Thanks!

[Dovecot] SSL CA root certificate
by Mail Admin 02 Aug '04

02 Aug '04

In reading through the mailing list, this question seems to have come up before, but never quite answered. I bought a certificate from Digital Signature Trust which is a well known certificate authority. The reason I bought my certificate, was so that email clients connecting to my imaps server wouldn't be bothered with warnings of unrecognized certificate authority as they would see with a self-signed server certificate. However, I haven't been able to configure dovecot with my Digital Signature Trust signed certificate so that the unrecognized certificate authority warning doesn't appear. I have the root certificate for Digital Signature Trust, but I don't know where to put it so that dovecot will use it. I tried appending the CA root certificate onto my server's certificate file with no success. The answer here is not, load my server's certificate into thunderbird or outlook express, because that is exactly what I'm trying to avoid by purchasing my certificate from a recognized authority. Help. Thanks, Derek

I don't think simply changing user id for process does that. It's more likely because of this code in src/master/mail-process.c: /* NOTE: if home directory is NFS-mounted, we might not have access to it as root. Change the effective UID temporarily to make it work. */ if (reply->uid != master_uid && seteuid(reply->uid) < 0) i_fatal("seteuid(%s) failed: %m", dec2str(reply->uid)); ret = chdir(full_home_dir); if (reply->uid != master_uid && seteuid(master_uid) < 0) i_fatal("seteuid(%s) failed: %m", dec2str(master_uid)); /* If user's home directory doesn't exist and we're not trying to chroot anywhere, fallback to /tmp as the mails could be stored elsewhere. */ Dovecot just wants to set current directory to user's home directory as that's the most logical location. I hadn't thought about any automounters.. One way to fix it would be to not use home directories in userdb at all, instead set the "mail" setting in it. Then Dovecot would chdir to /tmp. Another fix would be to just delete the code above and make it always chdir to /tmp. Maybe there should be a setting for this? ..

[Dovecot] 1.0-test31
by Timo Sirainen 30 Jul '04

30 Jul '04

http://dovecot.org/test/ Fixed mbox corruption in some cases where it wrote headers over beginning of message body. Fixed recent flags to work correctly with mbox. Fixed LSUB command to send LSUB replies instead of LIST replies. Then there's NTLM support from Andrey (which I hopefully didn't break) and dovecotpw utility from Joshua. And then some generic status report: For last few weeks I've been trying to make all network I/O non-blocking but that work is going quite slowly. This means that IMAP and POP3 commands which send lots of data to client must be able to stop processing if output buffer is getting full and continue later. Not very difficult, but a bit boring to implement.. This would allow in future to make a single process handle multiple IMAP connections for same user. Although that might not be such a good idea since there's still lock waits and SEARCH command can take a long time.. Anyway, it makes the code less kludgy. Maybe in future we'll have non-blocking lock waits and file I/O too. Adding some support for threading might not be a bad idea either, as long as it doesn't require adding locks all over the place (threads would perform searches, threading, sorting, etc.). Oh, and another thing it enables is processing multiple commands simultaneously. IMAP supports that, although I don't know if any clients do it. So for example a client could send: 1 fetch 1:* envelope 2 status mailbox (unseen) Then Dovecot would process the fetch command until it's output blocks, then it would send the status reply in the middle of it and then again continue the fetching. The nice thing with this is that client can do some "urgent" requests in the middle of some long running commands without the need to create multiple connections to server.

[Dovecot] Problems compiling PHP --with-imap - can't find rfc822.h
by Chris Weiss 29 Jul '04

29 Jul '04

I'm trying to add webmail (IMP/HORDE) to my OpenBSD 3.5 mail server (Procmail/Amavid/SA/DCC/Razor/Dovecot 0.99.10.7), which means adding PHP and several other libraries. I'm building PHP 4.3 from the ports tree and, as per the IMP/HORDE readme files, added --with-imap to the makefile. Makeing PHP barfs with a "Cannot find rfc822.h. Please check your IMAP installation." error. I did some digging around and this seems to be part of Courier-IMAP and Mutt, but not part of Dovecot. Can this header file just be grabbed from Courier or Mutt and dropped into /usr/include? Is there something else that's got to be done here?

[Dovecot] dovecot mounts user home dir?
by TM 29 Jul '04

29 Jul '04

Why does dovecot mount the user home directory whenever the user checks his email (either pop or imap)? Is there a way to disable this? I have indicated in the default_mail_env = mbox:/home/%u/:INBOX=/mail/%u:INDEX=MEMORY. The users are in ldap. Windows users' home is in /home/%u so this is ok but unix users' home are in their local computers and are mounted (via automount) at /d1-data/pcname/username. Even if mounted, the users' home directory isn't used by dovecot since nothing gets written to it. The users only checks his pop mail but still, his home directory gets mounted. Is it possible that dovecot won't try to mount the user's home directory whenever the user checks his mail? Thanks a lot. ________________________________________________________________________ Yahoo! Messenger - Communicate instantly..."Ping" your friends today!

[Dovecot] Concerning: in 0.99.10.7 - Maildir: LIST now doesn't skip symlinks
by chris pickert 28 Jul '04

28 Jul '04

TSS/Dovecot: I saw the recent change in the ChangeLog about the 'subtraction' of the listing of symlinks. The point showed(minus): - Maildir: LIST now doesn't skip symlinks Does this truly mean the functionality was removed? I'd tried doing symlink'd maildirs in 99.10.6 w/ no luck and when I saw this change I hoped this was an addition, as it would be great in lieu of Dovecot's lack of ACL/Shared folders. If it was intented to be ADDED in the recent .7 release, it still doesn't work. If it was pulled (which is strange becauase my .6 release didn't do it), why? Are the .conf directives about it I'm missing by chance? (Didn't notice anything) I'm using Dovecot in combo with horde/imp and it's amazingly faster than courier-imap or uwash-imap, well done! What about the aforementioned ACL/Shared folders? I'm getting into a crux that I may need it and courier-imap-/-cyrus-imap will do my trick but, dovecot smokes them on performance! (Especially with horde/imp's preview/info stuff) Thanks! -- Chris Pickert

[Dovecot] weakness in hash salt generation
by Joshua Goodall 27 Jul '04

27 Jul '04

Dovecot has routines for password hashing; two of these, crypt_generate and md5_generate, both use sizeof(salt_chars) when reducing a random string to salt. I became suspicious when I noted that all salts generated are composed only of "./01". Unfortunately salt_char is declared static const char * rather than static const char [], and so sizeof(salt_chars) is the size of a pointer.

[Dovecot] Local + virtual users using Dovecot 0.99.10.6 (from debian testing)
by Alexander 26 Jul '04

26 Jul '04

Hi, I have configured the MTA (exim4) to put the messages for my local users at /var/mail. If the user does not exist as true unix user, it looks at a postgresql database and if the user exists there, it delivers the message at /var/mail/virtual Example: User fred is a unix user, and peter is a virtual user. If i send a mail to fred(a)mydomain.org, the message is stored at /var/mail/fred (im using exim's append for transport). If i send a mail to peter(a)mydomain.org, the message is stored at /var/mail/virtual/peter With the defaul configuration from debian, dovecot is capable serving the local users mailbox (and its working at the moment). Im using only IMAP (i see there is an option for pop3, but im not interested in that atm). I think i know how to change the config file to serve only virtual users using the postgres module. Can anyone tell me how to serve them both at the same time? As I understand it, what i need is to make dovecot try to validate a user againt the local user database (its using pam for that at the moment), and if it fail, try with postres. But i dont know how (or if its possible at all). Thanks.

[Dovecot] dovecot.conf: default_mail_env
by Sebastien 26 Jul '04

I just installed Dovecot on Debian and everyting seems to be working fine except for the fact that it can't seem to find my mails when I log in. All my mails are stored in the file ~/mail/Inbox. In the dovecot.conf file I put: default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u and it's not working. What is the part: mbox:~/mail/ for ? and what is the part: INBOX=/var/mail/%u for ? I read the documentation but I don't understand. Can anyone help me ?

[Dovecot] 1.0-test30
by Timo Sirainen 26 Jul '04

26 Jul '04

http://dovecot.org/test/ Mostly just fixes. Fixed some crashes with cache file. Fixed "randomly" occuring mbox parsing problem. Namespace handling was pretty much rewritten. Non-hidden namespaces will also show up in LIST replies now, so if you have eg.: namespace private { prefix = mboxes location = mbox:~/mail } Then clients would show "mboxes" as normal folder. Subscription file handling also changed and will probably change more.. Currently subscription file is specific to the namespace where the mailboxes are. So in above example subscribing to "mboxes/foo" would use ~/mail/.subscriptions file rather than the default. I'm not exactly sure if this is a good idea or not.. It probably needs to be configurable with some subscriptions = yes|no per-namespace setting.

[Dovecot] Passwords in passwd-file
by Andrew Boothman 25 Jul '04

25 Jul '04

Hi! I'm trying to use MD5 hashed password in a passwd-file (not the system one). I've set auth_userdb = passwd-file /my/passwd/file auth_passdb = passwd-file /my/passwd/file auth.txt additionally describes a syntax like: auth_userdb = passwd-file[34] /my/passwd/file to denote MD5 passwords in the file, but I've been unable to get any combination of using []'s after passwd-file to work. Dovecot complains: "Unknown userdb type". How is it best to store passwords in a passwd-file using Dovecot 0.99.10.7? Ideally I want to use PHP to generate the passwords being entered into the file. Thanks for any pointers! Andrew

[Dovecot] Bug? 1.0.0-test28 NFS locking problems
by Tim Southerwood 24 Jul '04

24 Jul '04

Hi Slight problem - linux 2.4 running dovecot, Solaris 2.8 home directory server. Full lockd support etc. I had to make the following code patches (at end of mail for clarity) to get dovecot to read the users mbox files at all. 1) fcntl with F_SETLKW will not work against a Solaris 2.8 server as proved with a small test program. Other forms of fcntl (ie F_SETLK) are OK. I noticed there are some code witches, but setting mbox_lock_timeout=0 only seems to knock one of the fcntl's over to F_SETLK 2) O_CREAT | O_EXCL are documented not to work over NFS properly (see man open(2) on linux). So I knocked out the O_EXCL and combined with (1) dovecot will talk over NFS to remote mbox files. THESE ARE NOT VIABLE CODE PATCHES They illustrate a problem I found - they are hackish and totally wrong. I'm not sure of the best way to correct this problem cleanly, so I am just submitting it as a potential bug.

[Dovecot] RFE: MD5 encryption with for plain text passwords
by Felix Schwarz 23 Jul '04

23 Jul '04

Hi, due to compatibility issues with mail clients I think I have to use plain text authentication. In order to secure the passwords during their transport I'll use SSL encryption. After reading some documentation I think that I'll have to store the passwords as plain text in the authdb. That is something I dislike very much as it is a (imho) good tradition for unix to store only encrypted passwords for security reasons. I would like to see the possibility in dovecot to store the passwords for plain text authentication md5 encrypted. That should be easy to implement (just one md5 encryption before comparing the given password with the stored one) and could improve security. As this would be an api change it should be made configurable (and in the first versions this setting should default to the actual behavior). How do you like this idea? Maybe I can provide a patch but I won't work on this if you won't include it within dovecot at all. And last but not least I want to thank you for your great support! I really appreciate it! :-) -- Felix

Hi, after getting dovecot working with PostgreSQL and plaintext passwords I tried to use md5 encrypted passwords with mozilla. www.roughtrade.net/dovecot says that Mozilla only supports CRAM-MD5 and that CRAM-MD5 is included in HEAD. Now I have two questions: 1) Is the md5 hash stored in passdb with cram-md5 the same as in digest-md5? 2) Is a new dovecot stable build planned within the next two weeks (which includes CRAM-MD5)? (I guess the answer is no :-( 3) Are there any dovecot rpms with pgsql and CRAM-md5 supprt? -- Felix

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.

[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

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.

[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.

Hi Using this line in dovecot.conf (ignore linewrap) default_mail_env = mbox:%h/IMAP/:INBOX=%h/.email:INDEX=/var/cache/dovecot/%n The INBOX indexes are being built correctly in /var/cache/dovecot, but all other indexes for folders are still being built in the user's home directory. I had it working once - but it seems fragile - almost as if the config parser is sensitive to context??? Sorry - seems vague, but I can't pin this down reliably. Anyone else had problems?

[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.

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.

[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

It's been there forever. Guess people have fast internet connections nowadays :)

[Dovecot] postfix patch does not compile on freebsd 4
by Kevin 13 Jul '04

13 Jul '04

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
by Jean-Francois Theroux 12 Jul '04

12 Jul '04

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?

[Dovecot] pop3 usernames

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

Still isn't as smart as it could, but it seems to work again. The code is nearing a state where plugins could add their own data into cache file.

[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
