A folder can itself contain mail but it can also contain subfolders, so this is needed. With Courier you probably got away with just enter-key because you didn't have such subfolders and Courier gives mutt hints about if folders have subfolders. Dovecot doesn't yet support that extension so mutt always assumes they have subfolders.

[dovecot] Maildir format
by gareth＠wiked.org 30 Dec '02

30 Dec '02

Started using dovecot and I am very impressed by its speed. I am confused by what it is expecting the format of the Maildir directory to be in. I currently have ~/Maildir which contains new, cur, and tmp all containing email that should be in my inbox and it pops up correctly as such when I connect to dovecot using Mutt. After the connection a new .INBOX is created under ~/Maildir with sym links back to new, cur, and tmp. The problem arrises when I want to view email from another folder, I have a folder called "test" which contains some email also in Maildir format, however when I attempt to view this email I only get an empty listing with the ".." to go one directory up. Thanks. Gareth Greenaway -- "My friends say I should act my age, What's my age again?" Gareth J. Greenaway | gareth(a)wiked.org

[dovecot] passwd-file; configure args..
by Jesse Peterson 28 Dec '02

28 Dec '02

I couldn't reproduce this again (because i can't get imap-master running due to problem below..) but.. When compiling without shadow, passwd, or pam, when logging in I get after a successful login (in my syslog): Dec 28 22:39:38 badcase imap(username): MAIL environment missing and autodetection failed (home /some/home/directory) Now I thought this was covered in a previous fix before (ChangeLog: "2002-12-17 03:00 Timo Sirainen <tss(a)iki.fi>") but for some reason it's broken again..? The configure args problem has to do with --localstatedir. If i leave it default (PREFIX/var) it forces me (even with non-relative pathnames in the config file) for the socket-files (ssl_parameters_file, login_dir) that should go in /var/run to be put under PREFIX, (/usr/local for NetBSD 1.6). Not too bad, if I could override it in the config file, which I can't. So I ./configure'd with --localstatedir=/, and when I run imap-master I now get: Fatal: Can't create directory //run/dovecot: No such file or directory Somewhat odd. Any clues on either of these would be helpful, thanks. -- Jesse Peterson erage(a)softhome.net

[dovecot] Dovecot splited fetch problem
by Hon 27 Dec '02

27 Dec '02

Hello, When I was trying out the IMAP server (using Mozilla as client), I have no success of receving mail with attachments. Looking it down further I've found that Mozilla fetches the message in 10k blocks, and the server seems missed a couple of bytes at where the split occurs... Mozilla start the fetch by saying: * 413 FETCH (UID 827 RFC822.SIZE 106371 BODY[]<0> {10240} -- snip to place of split -- zmmAWdUxYA6Aobczv4BguxSZGqdYs6ELNIpgjiPUdYLxsHy) 7 OK Fetch completed. 8 UID fetch 827 (UID RFC822.SIZE BODY[]<10240.10240>) * 413 FETCH (UID 827 RFC822.SIZE 106371 BODY[]<10240> {10240} 6BilWYuUJGA4YeNYFJbI1gL The resulting line (saved from Mozilla view source) is: zmmAWdUxYA6Aobczv4BguxSZGqdYs6ELNIpgjiPUdYLxsHy6BilWYuUJGA4YeNYFJbI1gL ^^ Two bytes missing Where the original is: zmmAWdUxYA6Aobczv4BguxSZGqdYs6ELNIpgjiPUdYLxsHygZ6BilWYuUJGA4YeNYFJbI1gL ^^ I have tried this using Debian packaged (0.99.4-1) and self compiled 0.99.5rc1.

[dovecot] 0.99.5rc1
by Timo Sirainen 22 Dec '02

22 Dec '02

Current CVS contains a lot of code cleanups which aren't too well tested. Seems to be working with me, but I'm still a bit worried I left some very nasty bug lying around somewhere. There's anyway been many nasty fixes since 0.99.4, most importantly with mbox handling and SEARCH command. I've also added support for SORT extension. It's not very fast currently, but it should work. I tested with squirrelmail and it looked fine. So, those people wanting to use Dovecot with webmail might try it now. :) THREAD extension is still missing though. So, here's a 0.99.5 release candidate 1. I wouldn't recommend it for production usage yet, but I'd hope some people to test it before I'll put out a real release. Just so that I won't be (again) releasing n+3 versions in a few days :) You can get the sources from http://dovecot.procontrol.fi/rc/ I'm going away for christmas tomorrow, once I get back I'll do some more testing and auditing and get the final release out. Next weekend probably.

[dovecot] dovecot replacing uw-imap
by seth vidal 20 Dec '02

20 Dec '02

Hey, I'm trying to sort out how to make dovecot replace uw-imap cleanly. But I have the following problems/questions: 1. Why is mbox support limited to user-owned directories? 2. Would it be possible to have dovecot target a different place than ~user/mail by default, specfically some place like /var/path/to/maildirs/userdir/ I'd like to move all my mail storage out of user homedirs and to central space on my mail server, increasing reliability and helping me manage disk space usage for readily. In order to use dovecot I need a migration path and that path looks like it will need mbox outside of the users homedirs and pottentially outside of solely user-owned directories. -sv

[dovecot] 0.99.4 uploaded to Debian

18 Dec '02

Hi, I'm the Debian maintainer of UW-Imap. Like many I'm somewhat frustrated with the limitations of it so I am very pleased to see that Dovecot is becoming a strong alternative. I have uploaded packages of 0.99.4 to the Debian unstable distribution (sid). Because this is a new package it has to be added by hand so it may be a while before it shows up in sid. In the mean time, I have made the packages (also for stable or woody) available from http://www.braincells.com/open/ Debian users, please take a look and give me some feedback. Unfortunately much to my embarrasment I can't currently use dovecot on my own account. I get a meesage like this in /var/log/syslog: Dec 18 09:01:31 samadhi imap(jaldhar): Error indexing mbox file /home/jaldhar/mail/inbox: LF not found where expected The mbox in question is about 17MB and opens fine in uw-imapd.

[dovecot] passwd-file access
by Jesse Peterson 17 Dec '02

17 Dec '02

Using passwd-file authentication I run into some problems.. This is my passwd file: user:0cc175b9c0f1b6a831c399e269772661[34]:6660:6660:0:/some/mail/directory/user:0::: My MUA tells me after enter my user/pass that the server disconnected, OK. So I netcat into the imap server, and issue an "C: LOGIN user a" in which case I get the error "Fatal: USER environment missing". So I search for this in the src and find in 'src/imap/main.c' on line 30 it checks for the environment variable USER.. which I assume it can't find because it's not an actual system user, it's a ficticious user in a passwd-file.

[dovecot] SSL + default_mail_env
by Jesse Peterson 16 Dec '02

16 Dec '02

in the config file i have "ssl_disable = yes", however, i get this in my LOG_MAIL syslog: "Dec 17 00:21:07 host imap-master: Can't create temporary SSL parameters file /default/configured/directory/ssl-parameters.dat.tmp: No such file or directory" I know what the error is, and how to fix it, but it's an SSL thing which should have been disable according the config file, correct? It would seem that if you surround the value given to default_mail_env in quotes (as listed in the sample config file) you get errors like: Dec 17 00:21:13 host imap(testuser): Failed to create storage with data: "maildir:/home/testuser/mail/" -- Jesse Peterson erage(a)softhome.net

[dovecot] Maildir problem..
by Jesse Peterson 16 Dec '02

16 Dec '02

I have the most interesting problem... I've compiled dovecot from CVS with a checkout on 2002-12-15 around 23:00 PST. When I select a message in my MUA I can view it and stuff, however, if I select another message, or folder, the message disappears. It appears that dovecot shortens the Maildir message name to ":2,S" and then you can't access the message from the MUA again. The same happens if you try and move a message from a foler to another folder.. Any ideas? -- Jesse Peterson erage(a)softhome.net

[dovecot] Maildir detection..
by Jesse Peterson 12 Dec '02

12 Dec '02

It would seem that dovecot cannot detect my maildir. The system DO NOT use "~/Maildir". It is arbitrary across a few systems, actualy, and am curious if there is a way to "force" in the config file where the maildir explicitly resides, much like Postfix's "home_mailbox" configuration parameter. On a side note, I compiled dovecot 0.99.4 on a NetBSD 1.6-release i386 machine, it when imap_listen is not set in the config file, it only binds to the tcp6 ::1 address. Any clues? -- Jesse Peterson erage(a)softhome.net

PAM can only be used for checking if user/password matches, so it's missing the passwd information that Dovecot needs, at least home dir and uid.

I assume a database should have to be faster, but this is just an > assumption... That's mostly because of a few tricks that Dovecot does with it's index files that aren't really possible with SQL databases. Multiuser mailboxes which are modified a lot are one thing where they could be faster than Dovecot's index files because of better locking. Besides, Dovecot's indexes could be called as a simple database..

[dovecot] questions
by Farkas Levente 05 Dec '02

05 Dec '02

hi, I'm look around to find a usable imap server and find dovecot. I read all the docs, but I've got a few questions: - currently we use courier (since we find and install it quickly). can we switch from it to dovecot smoothly? or we have to convert the maildirs somehow? - I've got a few plan in my mind it it possible to do it with dovecot now or in the near future (if yes what is the estimated time)?: - authenticate from LDAP, the best would be trough PAM? - use the same user with different domain. eg: lfarkas(a)bnap.hu, lfarkas(a)bppiac.hu with the same imap server? handle more domains. - use imaps and use Digest-MD5 and/or CRAM-MD5? - put a database backend under imap and store the mails in a database. - use WITHOUT local users? it's very important! most case a user never ever log into the local system and I would not like to put them into /etc/password. - do it all the above at the same time!? thanks. -- Levente http://petition.eurolinux.org/ "The only thing worse than not knowing the truth is ruining the bliss of ignorance."

[dovecot] Sieve

Hi all, I'm using Dovecot for some months now, and I love it! I also saw that there are 'plans' to integrate Sieve support. Well, some days ago I saw the following on freshmeat: libSieve - http://libsieve.sourceforge.net/ libSieve is a standalone library pulled from CMU's implementation of their Sieve mail sorting library in the Cyrus mail server. Either shared or statically linked, libSieve will help to bring mail sorting functionality into your mail server application without the need to reinvent the wheel. As a library, it is not intended for end users expecting a ready-to-run program. Maybe this could ease the Sieve integration ? If I got some spare time I'm going to contribute some code for it myself. greets

[dovecot] dovecot and pop3
by Paul C. Bryan 27 Nov '02

27 Nov '02

Dear dovecotters: I'm becoming interested in dovecot as a replacement for UW-IMAPD. Any project that claims it's the "postfix of ____ servers" deserves a looksee. If indeed I were to going to switch at some point, I'd need to replace the UW POP3 server (which is a part of the UW package). I would prefer one that actually used the dovecot IMAP server instead of going to the filesystem directly. Question 1: Anyone know of such a POP3 daemon that connects to the IMAP server. Question 2: If the answer to Q1 is "no", would anyone be interested in such a package? Yours truly, Paul C. Bryan email(a)pbryan.net

Normally this couldn't happen without error in configuration. - select() based I/O loop wasn't working so Dovecot didn't work in eg. OSX.

I figured now would be a good time for new release.

NOTE: currently doesn't work with OpenSSL. + Support for each login connection being handled in it's own process. This is the default as it's more safe especially with SSL. + mbox locking is now safe, other processes can't modify the mbox file while we're reading it. + Notify clients with "EXISTS" almost immediately after new mail is received. + Rawlog: Support for saving user connections into files - useful for debugging. + Content-Language is finally parsed correctly + Lots of smaller speed optimizations - Partial BODY[] fetches weren't working properly - BODY[section] was buggy with message/rfc822 MIME parts - STARTTLS wasn't working - \* flag was missing from PERMANENTFLAGS. - Comments inside <> mail addresses crashed. - imap-login printed UTC timestamps to logfiles - passwd-file wasn't reread the the file changed - PAM authentication was implemented wrong, which caused it to break with some PAM plugins. - Lots of smaller fixes, mostly to do with reliability

Since you did get it to work by changing PAM to use shadow auth, Dovecot is doing it at least partly right. Maybe the radius PAM module requires something that Dovecot didn't do.. Looking at Courier's PAM handling, it does pam_setcred() which dovecot doesn't. You could try if doing that helps: src/auth/userinfo-pam.c, around line 169, insert between pam_authenticate() and pam_acct_mgmt(): if ((status = pam_setcred(pamh, PAM_ESTABLISH_CRED)) != PAM_SUCCESS) { if (status == PAM_ABORT) i_fatal("pam_setcred_mgmt() requested abort"); return FALSE; } > Maybe it dovecot sets a realm, which is then mistakenly used by > the pam radius module, but not by the passwd/shadow module? PAM doesn't have any support for realms AFAIK.

Dovecot currently wants the users to exist there too to get their UID, GID and home directory. I'll change this later so that you could give "gid=123 uid=456 homeroot=/var/mail" options to pam auth and it'd use them for all users. Or did PAM also support getting that information in some way? I'm not sure exactly..

[dovecot] vsnprintf()
by Thomas Wouters 23 Oct '02

23 Oct '02

I think I stumbled upon a bug in the i_snprintf() function. In the case of vnsprintf() being available, it depends on vnsprintf() returning -1 when the string was longer than the passed-in limit (or it won't terminate the string.). But this isn't the C99-standardized behaviour, and newer glibc's don't do that anymore either, so you can end up with a non-terminated string. This patch should fix it, I think.

Installed syncmail program what Thomas was wanting. It sends a mail of each cvs commit, including the actual changes in source. Otherwise the mailing list is read-only. Subscribing happens the same way as to dovecot list, ie. dovecot-cvs-request(a)procontrol.fi with subscribe in subject. Hmm. I think I should also separate the private/public cvs repositories running in that computer and provide anonymous pserver access..

[dovecot] Architectural questions
by Thomas Wouters 22 Oct '02

22 Oct '02

Greetings, I have some architectural questions regarding dovecot, and though I've half answered them by looking at the source, I'm also interested in hearing whether my (our) wishes and suggestions are already being considered (or can be considered, once built) for inclusion in dovecot itself. Let me first explain why I'm doing this. I work for XS4ALL, a fairly large ISP in the Netherlands. We provide a wide variety of services, including shell access, pop3, webmail, et cetera. We use Sendmail on several clusters of FreeBSD machines (loadbalanced using layer-4 ethernet switches) and several NetApp Filers (dedicated NFS servers with fail-safe disk-arrays and such) for backend. Several years ago (when we were a lot smaller) we noticed the typical use of the mailboxes included leaving much old email on the server, at least for a while, and that this is a bothersome thing when using mbox mailboxes. (The mboxes basically have to be copied over whenever the status of an email changes, leading to a lot of I/O.) We briefly played with modifying sendmail and the pop server to avoid the full copy in the common case (only status changes) by doing in-place edits of a pre-generated Status line, as well as avoid full scanning of the mbox file by creating special headers to mark the 'real' length of an email. It worked, for a while, but it wasn't going to scale very well. So we switched to maildir mailboxes for the mail spool. A modified mail.local (which we need for other reasons as well) delivers in /var/spool/mail/u/s/username, and mutt, uqwk, a modified pine and qmail's pop3 daemon read it from there. Until last week our clients could choose to have mbox inboxes, to use with 'elm' or 'mail', but we decided to discontinue that support. Our new shell servers, which are in test, don't have elm installed anymore anyway. We still have support for mbox mailboxes in a user's homedirectory though, by using procmail and such. So when we needed an IMAP server for use with our webmail (based on SquirrelMail), we were forced to go with the UW-IMAP server, with the maildir patch that's been scattered around the 'net. This worked, for a while; we also use the maildir patch with pine after all. However, the maildir patch is not very good. Not at all, even, and it only seems to work by pure chance. Pine works for the average user who does not get a lot of new mail while his pine is open or does not use procmail, and fortunately a lot of the people that do get a lot of email use mutt, which does work properly. The UW-IMAP server worked fine because SquirrelMail only uses (used) a small subset of the available functionality. But that's changing, as SquirrelMail gets actively developed, and we're also considering other IMAP-based services. But we can't switch to Courier or Cyrus because we need mbox support. And while looking for mbox patches for either of those two, I ran across dovecot. Yay! :) Dovecot is not everything we'd want, but it comes very close, and contrary to UW-IMAP both the design and the actual source code are clean, readable and logical, which means we can add the features we need and support them. What we need and want to add is fairly simple, but I've only been looking at dovecot since yesterday so I'd be happy to hear if any of it is possible, feasible, unwise or unacceptable. - First off, we need the maildir support to be 'correct' in that it does not rely on the naming of the files in the mailbox, other than the very loose specification DJB gives (doesn't contain a colon or slash and doesn't start with a dot.) The pine/UW-imap patch breaks here because it depends on the first part of the filename being time() or something else that, when sorted alphanumerically, puts new mail at the end. Our LDA does this, but procmail does not, and it shouldn't have to. - Second, we need the maildir support to be 'correct' in that it does not rely on the directory order being persistant. The NetApp Filers use btree-indexed directories, so the order of readdir() can change completely whenever a file is added or removed. The pine/uw-imap patch relies on the '.uidvalidity' file being modified whenever the maildir sort order changed, and this isn't happening. I *think*, from reading the sources, both of those are correct already. If they aren't, I'd strongly urge you to fix it, as #1 is a problem for anyone using procmail and #2 is a problem for anyone with 'indexed' directories (including such new filesystems as reiserfs, and I assume FreeBSD's new hashed directories.) - We need to avoid using fcntl(). The Netapps support it, but file-locking over NFS is very, very poorly designed and we've had too much problems of various kinds before, with fcntl. We also don't like the idea of having thousands of fcntl locks at the same time ;P Instead, we've switched to the locking method described in the Linux open(2) manpage under O_EXCL. (We call it 'dot-locking', I'm not sure where the name came from.) The actual implementation of that method is pretty simple, and I have a C version and a Python version hanging around here somewhere (the Python version is being used by GNU Mailman, last I looked.) If we're going to use dovecot, we will replace most, if not all, fcntl()s with dot-locking, the question is whether you want it contributed to dovecot :) - Every user's incoming mailbox is /var/spool/u/s/username. Other mailboxes are in /home/u/username/mail or /home/u/username/Mail (the second if the first does not exist.) We are not yet certain whether we want the inbox to be able to have subdir-mailboxes, as /var/spool and /home have different quotas and we urge people not to store their mail on /var/spool. (for one thing, it doesn't get backed-up.) We want these things to work without magical symlinks or empty files, because people _will_ delete them and cause unnecessary helpdesk calls :) Again, the question is mostly whether this is desirable in dovecot (or something enough like it to reduce local changes.) - We have over 300k mailboxes at the moment. We expect that number to keep growing. The indexer process (as described by design.txt) does not sound as a good idea in our case :) How necessary is it, really ? Especially since we do not expect more than 10% of those mailboxes to be actually used by IMAP, not even once. If disabling the indexer completely just means longer startup times for IMAP sessions, we can live with that. - The UW-IMAP maildir patch stores UID's in the indiviual filenames, using a 'U' flag. Will this interfere with dovecot ? We don't really need dovecot and UW-IMAP to share UIDs, but we would like to have an as painless transition as possible, without having to rename millions of files to remove the U flag and other flags :P It would also be nice to keep pine using the existing maildir patch, even though very few IMAP-users would use pine. - Would dovecot scale, architecturally speaking, to 500k+ active mailboxes ? The amount of hardware is not really an issue, we can add a lot of machines (off-the-shelve intel hadware) to each cluster, but if each dovecot process has to load in an index of all possible mailboxes... that would be a problem. Doing an inordinate number of file-accesses over NFS would also be a problem, but I haven't seen any indication of that in the source, yet. In case it wasn't clear yet, I'm very happy to have found dovecot. The lack of a decent mbox IMAP server has always dismayed me, let alone an mbox+maildir one :) I should also point out that even though XS4ALL is a commercial company, we would contribute our changes even if the licence didn't require it, and we want to contribute them back the way you want them, not necessarily the way it's easiest for us. We have a lot of experience with opensource software, as a simple google on my name should indicate ;P Regards, -- Thomas Wouters <thomas(a)xs4all.net> Hi!

One is for the IMAP server, which is an old version ('uw-imap-2000' or something like that comes to mind, but it came from the pine 4.10 source) from before the mailbox->append prototype changed (but with Mike's bilennium-patch.) A big problem with later patches was that the append method changed in the pine source, but not in the maildir patch. We considered using a newer uw-imap but decided that the current one works good enough ;P For pine we currently use the patch that comes with Debian's 'pine-tracker' package (which is an installer for pine with patches, since you aren't allowed to distributed modified binaries.) This patch also has some Mike in it, but I'm not sure howmuch, as at least parts of it seem to be backed out later. This patch works okay except for the two problems I noted in my original mail: it depends on directory order not to change except when '.uidvalidity' gets touched, and it depends on alphanumerical sort order of files matching chronological (or at least uid-based, which should be the same) sort order. The latter breaks with (standard) procmail, the former occasionally with btree and (presumably) hashed directory indices. > The storage of RFC822.SIZE, aka the on-the-wire size, in the filename > makes a very big difference to performance. That's interesting. I'll keep that in mind for when we begin to see performance issues with UW-IMAP. (I'm hoping I never have to look at the pine source again, though.) > But even this patch (from, e.g. > http://www.star.le.ac.uk/~tjg/misc/uw_imap-2001a_maildir-02.patch) has a > number of bugs.

The fixes are: <snip fixes> I couldn't find the source RPM for pine or (uw-)imap in that directory, but it doesn't sound like your changes solve our fundamental problems. It's not that big a deal, I think we've decided internally (I know _I_ have :) that we can't offer real IMAP services based on UW-IMAP; we'd sooner go for Cyrus or Courier, even if it does mean disallowing mboxes with IMAP. But dovecot is an even better alternative, once it has all the features we need :) -- Thomas Wouters <thomas(a)xs4all.net> Hi!

[dovecot] observations/qestions of mbox concurrency ability (Yay!) on current CVS
by Ian R. Justman 20 Oct '02

20 Oct '02

Hi, all. Just been testing out the latest "CVS" (in quotes because I'm rsyncing the source tree) versions of Dovecot lately. Tested having Pine on the machine on which Dovecot was running, talking IMAP, as well as another Pine instance, this time from my Windows machine over the wire. Things seem to be working wonderfully. Deleted a message using one instance, then refreshed the list on the other. *poof* Gone. Though I'm seeing periodic "IMAP protocol error" messages in Pine, but they don't seem to be affecting the software's operation that I can see. Anything in particular I should be on the lookout for? Otherwise, you just made my day. Correction; week. :D --Ian.

[dovecot] Benchmarks
by Timo Sirainen 10 Oct '02

10 Oct '02

Just tried Dovecot with 85k mails from Linux kernel mailing list, total of 357MB. I mostly wanted to see if the new binary tree file works well. And it does :) Nothing gets slowed down after deleting messages all around the mailbox. I tried several things with Dovecot, UW-IMAPd and Courier. You'll see that Dovecot is faster in everything else except raw I/O which is a bit strange, have to look why. I think the most important thing anyway is the time spent opening mailbox. Clients are doing "STATUS mailbox (UNSEEN)" very often and that has to be fast. With Dovecot it's so small that I didn't even bother adding it to the benchmarks, with UW-IMAPd it's 16 seconds, with courier 2 seconds. Full results can be found at http://dovecot.procontrol.fi/dovecot-benchmark.txt
