It's hung up in SSL_CTX_use_PrivateKey() in ssl-proxy-openssl.c, which as you correctly surmised below, is due to a password protected key. I've located and used mkcert.sh. As a note the only docs for doc/mkcert.sh are halfway through the NEWS file and rapidly receeding as you add new releases, (congrats on the fast progress by the way!), however you might consider adding a short note about it to the doc/auth.txt or doc/configuration.txt file for those new to dovecot. > > > I do call fflush() after each write to log.

After playing a bit, I think that those messages were due to the kill -9, SIGTERM is nicer. I still end up with little in the way of verbose debugging messages, by my standards. Usually all I see is login and logout messages. Otherwise, I get the occasional lockfile message, which is something that I need to sort out with Exim, and completely on my end. > > dovecot: Feb 20 18:11:51 Info: Dovecot starting up > > imap-login: Dec 31 16:00:00 Fatal: Can't load private key file > > /usr/local/ssl/private/cedarintkey.pem: error:0906406D:PEM > > routines:DEF_CALLBACK:problems getting password > > Err, isn't this the reason why your SSL doesn't work? :) Or was that > just an example? If your private key is crypted with some password, > Dovecot can't use it at least currently.. Correct! Doh! I have been able to use imaps, since I built a non-passworded private key. I was using passworded keys that I'd built for Apache, and would eventually like to have one set of keys that I can reference for each virtual domain. Were you planning on something like the Apache startssl option? I can live with the constraint of one 'connection' key for now. Have you considered allowing each virtual domain to have it's own keys? Kind of difficult as the secure pipe to the server is already in place by the time the login name is seen... Kinda makes it tough for a true virtual presence without explicit assigned IP's. Hmmm, any plans for at least a different keys/identity per IP? If I understand the configuration file for now, it seems to be designed for one cert per machine. Thanks for the help, I've just got to sort out the lockfile differences between Exim and Dovecot and I should then be functional. After that I'll start using LDAP. TJ

[dovecot] Trouble setting up dovecot
by Tim Snider 21 Feb '03

21 Feb '03

Hi, I'm new to the list but have been trying to get dovecot configured for the past week and a bit. I've gone through the list archives and solved a few of my problems, but most don't seem to be addressed. First off I want to say thanks for starting this project, I've been hoping that someone would start an IMAP/POP server with some flexibility in the way it's configured and provides both packages in one.I've tried setting up Courier once and found it onerous, UW was easier but forces a bunch of assumption that don't suit the way I wanted to configure virtual mail. I'd love to run dovecot, eventually with LDAP and Jamm, and Exim to handle my virtual domains, however I'm running into a fair number of problems and haven't had any luck getting past them. I'm running a RedHat 7.3 SMP server, with iptables for a firewall, so I've got several cards and thus IPs.I started out with dovecot 99.4 but noted that it was missing the LDAP, tried 99.8-test5 and am now working with 99.8-test7, both seem to have the same problems. I'm currently trying to setup a IMAP server on the inside of the firewall, 192.168.2.X. If I use just imap, turn of SSL/TLS I'm fine, and can do plaintext authentication via shadow, but I can't get PAM authentication working. If I turn on SSL(ssl_disable = no), neither the imap or the imaps respond and a netstat -tp shows that no process owns the socket PID/process = '-', often with characters in the Recv-Q. I've tried turning on all the debugging flags for configure on, --with-rawlog --enable-debug --enable-asserts --with-ssl=openssl as well as verbose_proctitle = yes, and auth_verbose = yes, setup logfiles /var/log/dovecot/messages, yet all I get are authorization messages. And I've noted that a number of them only show up after I've killed the dovecot process, so I'm wondering if there needs to be a bit of flushing somewhere? As well I've also tried to run "dovecot -F", with the log files commented out in the .conf file, but get nothing via stderr. I note that when I try the log_timestamp option, the dates sent from imap-login are completely incorrect and don't change, so I don't think the date is being read correctly. Is log_timestamp operational? One thing I'm not clear on is what process to run it under, I've setup a user/group 'dovecot', but does dovecot have to be a member of wheel? I've also noted in earlier versions you had things running via imapd-master, but that now seems to been replaced by "dovecot", is that correct? Is anyone else running dovecot on a SMP system? Any comments or suggestions? I do have development experience, but my Linux/UNIX programming is a bit rusty. I'd love to help make this a rocking product, but need some help getting it dovecot up and running. Any help is appreciated. Thanks, TJ timsn(a)thtree.com http://www.thtree.com/People/TJ/Resume.html

[dovecot] 0.99.8-test7
by Timo Sirainen 20 Feb '03

20 Feb '03

OK, I really should release 0.99.8 final soon, but not just yet :) Mostly just documentation updates left I think. There's a few recent changes that might have some nasty bugs: - problems with copying messages from mbox to another should be fixed now - LIST and subscription handling rewritten. - "mail_read_mmaped = no" used to corrupt mboxes when expunging messages. It now enabled again by default, and it seems to be working. I did update my backups though :) Dovecot's LDAP support currently requires that it can read the userPassword field of every user. I'm not sure if I should support "authentication binds" that seems to be more standard way to do LDAP authentication. That's just slower, works only with plaintext authentication and makes my code more complex.

Hi, I've tried other outlook installs and setting. When I try to copy a folder to the imap account I get... "Can't move the items. The move operation could not be completed. It is possible that the destination server is unavailable or does not support subfolders." And when I try to copy mail to the imap folder (with subscribed folders) I get: "Can't move items. This IMAP command could not be sent to the server before the connection was terminated" I get some corresponding errors in dovecots logs: " imap-master: Feb 18 18:31:41 Error: child 60038 (imap) killed with signal 6 imap((null)): Feb 18 18:33:49 Panic: file cmd-append.c: line 25 (validate_args): assertion failed: ((unsigned int) ret == count) imap-master: Feb 18 18:33:49 Error: child 60042 (imap) killed with signal 6 " related? > On Tue, 2003-02-18 at 18:56, Kevin Lee wrote: > > Hi, > > I have tried multiple dovecot versions (0.99 and CVS) and I keep > > getting the same problem. > > > > I connect to the IMAP server fine using outlook xp, but when I try to create > > folders it creates them and then they just disappear.

[dovecot] IMAP folder problem
by Kevin Lee 19 Feb '03

19 Feb '03

Hi, I have tried multiple dovecot versions (0.99 and CVS) and I keep getting the same problem. I connect to the IMAP server fine using outlook xp, but when I try to create folders it creates them and then they just disappear. In the Maildir on the IMAP server the folder are there but they don't show up using a client. I basically can't do anything with folders, including copying outlook folders to the server or create/delete folders. And when I move mail to specific folders using procmail it just gets put back into the inbox again... I'm using freebsd 4.7-RELEASE My config file only adds the following lines... auth = plain auth_methods = plain auth_userinfo = password-file /etc/passwd.imap auth_user = root My password file (/etc/passwd.imp) only consists of kev:XXXXXchangedXX[13]:1001:1001::/home/kev:::: I've just created a folder /home/kev/Maildir where dovecot created the MailDir hierarchies. Any help would be appreciated. Cheers Kev

I am NOT speaking to maildir, nor to Cyrus, nor to SQL-enabled products. Solely to mbox. In fact, I even said that stuff that talks to maildir, in addition to Cyrus, offered the one thing for IMAP you could not get with mbox until Dovecot came along; something resembling robust dealing with multiple clients to the same mbox store. Nor am I particularly insterested in debating the merits of any format over mbox, a format I have stated I -KNOW- has annoying technical limitations and issues. While I would imagine other formats may have advantages over mbox, I continue to use mbox simply because of the sheer amount of stored mail I have accumulated on all my machines for the past seven years. My point is that Dovecot seems to be the most robust IMAP server I have come across at coping with mbox stores, especially if I am trying to access the same mailbox with two different clients, whether intentionally or inadvertnetly. My hope is that Dovecot's POP3 server will prove just as robust at dealing with mailboxes that may also be open by an IMAP client. Whether Dovecot, BINC IMAP, or even Courier IMAP (or whichever POP3 server for that matter) are better for maildir or anything else, I will leave that debate to those who actually use them. In the end, I have made a choice. Not necessarily the best one, but I made the choice with the full understanding of what that choice would entail. However, you never know. I may change my mind later. ;) --Ian.

Here is what -I- would say: I use mbox on all my servers which I have absolutely no intention of changing despite the issues concerning file locking inherent in the whole mbox format. So please, --NO-- attempts to convince me to go to maildir. My take is that if I am going to use an IMAP server, it would be VERY nice if a POP3 server also came bundled with it. Dovecot's having both IMAP and POP3 servers is great because they will likely use the same file-locking schemes (in fact, probably even share the same locking settings). That way if I inadvertently start up a POP3 session while I am connected via IMAP, if they use identical locking mechanisms, I don't screw up my mailboxes should I inadvertently tell my system that I want to delete the messages from my mailbox. Basically, if you open via IMAP using a server with a diffent locking scheme while your hung POP3 session is still running AND you modify your mailbox, you are screwed. Especially if that mailstore is NFS-shared, which is always a dicey proposition. Additionally, the number of mbox POP3 servers which Do Not Suck(R) is rather low right now. Timo finally introduced an mbox IMAP server which definitely Does Not Suck, notably it allows for multiple clients accessing the same mbox mailstore, something previously only offered by Cyrus and perhaps maildir ("perhaps" only because I do not use maildir). Not to mention, quite frankly, most mbox POP3 implementations suck pretty badly anyway. :P --Ian.

Yes, and I wouldn't have done it if it hadn't been so easy. I don't really encourage people to use it anyway, it's even disabled by default. If it has bugs, it doesn't affect the IMAP side. If people really need to run both IMAP and POP3 servers, it is simpler to use the same configuration for both, especially if the configuration isn't "standard" (eg. LDAP or SQL authentication, mailboxes in special locations, etc). All other major IMAP servers provide their own POP3 servers as well, if you haven't noticed :) > Donald Knuth said in a seminar that I attended that the best way to keep a > program free from bugs it to complete it. Finish off the project, work on > fixing bugs. That's Binc IMAP's philosophy. That's the ideal situation, and even possible if you keep the original goals. But there are IMAP extensions which may require large changes, new mail storage formats and ways to deliver mail into them, clustering, etc.

Sorry, I just got a bit disappointed after reading the the web page first. Your lines of code comparisions just seemed to imply that your server does everything that others would but with only a fraction of code. There was also something about Dovecot's design being too complex, so I thought you might have solved those problems more elegantly. When you write something from scratch, I think it's a good idea to design it so that it's superior to existing implementations in at least some ways, not just make a clone with slightly different coding style. If all you wanted was a clone with some changes (and better maintainer), forking the project would be much smaller job. Well, here's some design thoughts: Maildir implementation could be hidden behind a class to access it. That would keep the ugly details hidden from the rest of the code, as well as allow easily implementing other mail storages. Restricting yourself to only plaintext authentication doesn't sound very good plan. Separating the pre-login process from post-login process would probably be a good idea to keep their functionality completely separated. It would also be easier to audit the pre-login code if you knew exactly what there is. After logging in, you could just exec() the post-login process.

Fixes several smaller bugs. Finally works with FreeBSD (tested with 4.7 and 5.0). I think there's still some problems with authentication failing sometimes due to memory/ipc corruption. I haven't seen those today, but I don't think I've fixed that either.. One behaviour change is that if default_mail_env isn't set and mbox format is detected (~/mail dir), /var/mail/user or /var/spool/mail/user is used as INBOX if found.

I think all of the reported bugs are again fixed in CVS, so I made a tarball of it. I'd like to hear if there's any problems with it. Here's the most important changes: v0.99.8 2003-02-xx Timo Sirainen <tss(a)iki.fi> * NOTE: Configuration file has changed a bit: auth_userinfo was replaced by userdb and passdb. *_port were merged into *_listen. Disabling listening in imaps port is now done by changing protocols setting. + Fully featured POP3 server included. Disabled by default. + Support for LITERAL+, MULTIAPPEND and UNSELECT extensions. + Internal API cleanups made Dovecot faster and take less memory + auth_verbose logs now all authentication failures + Support for Solaris 9 sendfilev() (not really tested) - COPY now behaves as RFC2060 says: "If the COPY command is unsuccessful for any reason, server implementations MUST restore the destination mailbox to its state before the COPY attempt." - maildir_copy_with_hardlinks = yes was broken. - mboxes in subfolders weren't selectable. - STORE didn't accept multiple flags without () around them - PLAIN SASL-authentication was a bit broken. - IMAP dates were parsed a few hours wrong - If auth/login process died unexpectedly at startup, the exit status or killing signal wasn't logged. - mbox parsing might have crashed sometimes - Next command after STARTTLS was ignored which left the connection stuck sometimes - STATUS command removed \Recent flags from messages - Several bugfixes to SEARCH command, especially related to multiple search conditions

[dovecot] Recent messages
by Jaime Medrano 03 Feb '03

03 Feb '03

Dovecot seems to manage \Recent messages in a weird way. When a STATUS command is performed in a mailbox, then the \Recent flag of its messages disappear and latter STATUS commands report that there are no recent messagges. I don't know exactly the behavior of the RFC. But other imap servers (UW-imapd, Netscape Messenger...) report the same number of recent messages when two STATUS commands are performed together. -- Jaime.

[dovecot] mbox & Maildir
by james broermann 18 Jan '03

18 Jan '03

Hi, Is it possible for a client to read both mbox and Maildir formats from one server running dovecot? Without changing default_mail_env in dovecot.conf, Maildir folders are working ... they're located in ~/Maildir. No /var/mail/username exists. I have mbox format folders in ~/mail and have been trying to get pine to find them by adding pine folder collections. I always end up back in ~/Maildir, though. Thanks, Jim

[dovecot] 0.99.6 buggy
by Timo Sirainen 14 Jan '03

14 Jan '03

Just a note, the hash table code in it was still buggy. Especially with maildir it could leave the processes to infinite loop. Have to think a bit more how to fix this properly..

[dovecot] security audit of the code

Timo, I know that you're taking an effort to make sure that dovecot is written securely, but I was wondering if you've asked any third party to audit the code yet. I don't have the skills necessary to do this but I bet there is someone out there who does and might be willing to do so. -sv

[dovecot] 0.99.6rc3

14 Jan '03

Well, "release candidate" wasn't really right name for last two versions. Maybe not for this one either, it has a few changes that could potentially break things badly (new hash table code especially). Anyway, seems to work with me. If I don't see any problems with it for a few days it'll be the final. The really great news is that we support threading. A lot of people have not used Dovecot simply because it couldn't be used for webmails. Hmm. What's the next most important feature? .. Better mbox support? Shared folders? Quota? LDAP/MySQL/etc. authentication? Here's the change summary: v0.99.6 2003-01-xx Timo Sirainen <tss(a)iki.fi> + THREAD=REFERENCES extension support.

However on the mail server with the same config I get the following message when I try and authenticate, and it drops the connection. Failed to create storage with data: mbox:/var/mail/martin The test box is running debian unstable and the mail server is running debian stable so I had to recompile and install.

[dovecot] Thread extension
by Timo Sirainen 10 Jan '03

10 Jan '03

Just figured I'd mention that CVS supports now THREAD extension. I also did a bit of benchmarking using a folder with 4685 mails (evolution mailing list): dovecot+mbox: - 0.59s user 0.01s system 98% cpu 0.608 total - malloc() memory usage 45072 -> 825685 dovecot+maildir: - 0.60s user 0.17s system 98% cpu 0.780 total - malloc() memory usage: 45003 -> 825480 Meaning it takes almost 800kbytes of memory and it's quite fast :) Comparing to other servers then: uw-imap: - 1.11s user 0.27s system 100% cpu 1.376 total - malloc() memory usage: 529408 -> ~4348k courier: - 7.27s user 0.28s system 99% cpu 7.567 total - malloc() memory usage: 181689 -> ~850k cyrus: - 1.403 total (through TCP connection, I couldn't figure out how to start it separately) Whoa, we beat everyone :) Courier uses a bit less memory though, but that's most likely because we allocate it in larger chunks which is faster. I ran the tests several times and picked the best values, although the changes were minimal once they got the messages into OS's cache. Also it looks like I've found a couple of bugs in uw-imap and courier's implementation..

[dovecot] Logging suggestions?
by Timo Sirainen 09 Jan '03

09 Jan '03

Any suggestions how user login/logouts should look like in log files? I was thinking: (connected to imaps port) Login: username [IP 1.2.3.4, imaps, compressed] Logout: username [IP 1.2.3.4, imaps, compressed] [1000/100000 bytes (50%), 00:00:12] Bytes being upload/download and the 50% meaning compression ratio for downloaded bytes, probably not worth it for upload. Or if uncompressed, it'd show the extra space used by SSL/TLS protocol: (using STARTTLS) Login: username [IP 1.2.3.4, TLS] Logout: username [IP 1.2.3.4, TLS] [2020/202000 bytes (101%), 00:00:12] (no SSL) Login: username [IP 1.2.3.4] Logout: username [IP 1.2.3.4] [2000/200000 bytes, 00:00:12] I think the only configuration needed would be if to log login, logout or both.

[dovecot] Bug#175509: dovecot: init.d script should add some syslog statements on startup/shutdown (fwd)
by Jaldhar H. Vyas 09 Jan '03

09 Jan '03

[Amelia and Timo. As you are both on the dovecot list, I'm replying there to avoid cluttering up your inboxes.] This bug was reported to Debian but I feel it should be fixed upstream. Adding logging in th init script itself would require adding additional dependencies to the package and not be as convenient. ---------- Forwarded message ---------- From: Amelia A Lewis <amyzing(a)talsever.com> It would be nice if the init.d script could add some statements in the system log on startup and shutdown. For postfix, postfix-script (called from the init script) uses: starting the Postfix mail system stopping the Postfix mail system These are useful; one can start the daemon and check that it's initialized (netstat works as well, I suppose, but this is still useful docco). -- Jaldhar H.

If client had already successfully done the BODY fetching a couple of times, the bug couldn't happen anymore since Dovecot then began caching the BODY data.

[dovecot] Assert in imap-bodystructure.c

First let me thank you for my initial newby question about poping from a pop3 server and delivering into my Dovecot maildir folders. Now I'm getting an assertion in imap-bodystructure.c and one of my imap folders is now inaccessable. I think the two are related.

I've included a portion of the log below. I am running dovecot 0.99.5.

[dovecot] Weird problem on Alpha
by Amelia A.Lewis 06 Jan '03

06 Jan '03

Heyas ... Hope you aren't tired of me already .... I have a very strange problem, I think. Having become happy-happy with dovecot, I decided to install it on another machine that runs on an internal network and provides mailboxes for system monitoring. The setup is, or should be, quite straightforward. TLS is disabled, plaintext is not (I'll change this later, probably; this way is in theory easier to debug). Maildir; the MAIL environment variable is correctly set. Authentication via pam, for real users on the system, auth_user root. Pretty much as-distributed, except for disabling TLS. On attempted login, the client hangs. The following two messages appear in syslog: Jan 5 21:42:43 talifane imap-master: login: received another "not listening" notification Jan 5 21:43:43 talifane imap-login: Disconnected: Inactivity [127.0.0.1] Watching on lo via tcpdump, interesting things happen. If I login with the wrong password, the disconnect is quick (the message in syslog is different, just "Disconnected [127.0.0.1]" from imap-login). The server responds to the a0001 LOGIN command with a0001 NO Authentication failed. That's as expected. If I give the correct password, though, the server never responds. Note that the 'not listening' message appears sixty seconds before the disconnection for inactivity message. In tcpdump, it's clear that the client never gets anything that would give it reason to try another command. So ... have I managed to pull a total bimbo and misconfigure? Or is this a problem with the Alpha platform? I wanted to check before reporting a bug, but this is kinda strange, since it's about the simplest configuration that I can think of. Suggestions (for testing, or for fixing) would be welcome. Is there a way to start the daemon in a particularly verbose mode? In case it's useful, here's what the debian reportbug system generates for dependencies and stuff (0.99.5-1): -- System Information: Debian Release: testing/unstable Architecture: alpha Kernel: Linux talifane 2.4.19 #1 Sat Aug 3 10:33:38 EDT 2002 alpha Locale: LANG=en_US, LC_CTYPE=en_US Versions of packages dovecot depends on: ii libc6.1 2.3.1-9 GNU C Library: Shared libraries an ii libgcrypt1 1.1.10-2 LGPL Crypto library - runtime libr ii libgnutls5 0.6.0-2 GNU TLS library - runtime library ii libpam0g 0.76-9 Pluggable Authentication Modules l ii libtasn1-0 0.1.2-1 Manage ASN.1 structures (runtime) ii openssl 0.9.6g-10 Secure Socket Layer (SSL) binary a ii zlib1g 1:1.1.4-8 compression library - runtime It's specifically a PC164LX/533, 512MB RAM.

[dovecot] wierdness with mailboxes
by David E. Storey 06 Jan '03

06 Jan '03

Mail has always been the bane of my sys-admin life. I've been looking long and hard for a small, C-based, simple IMAP server that worked well with maildirs *and* mboxes and nothing else. wu-imap is so bloated and rife with decrepit, cross-platform, insecure code that I avoid it for any new servers. Courier-imap only supports maildirs but has some wierdnesses that I've come to live with. dovecot promises to be exactly what I'm looking for with just the right footprint and feature-set. =) I was surprised when I tried creating subfolders of mbox's. woohoo! The only problem is that dovecot manages to rename the parent, appending a '.'. So when we have: folder we now have: folder. folder.subfolder Evolution freaks out and thinks it can't store folders in 'folder.' and ends up with two subfolders: null and subfolder, which can contain messages. If I rename the parent folder without the trailing '.', everything works as expected. I'm trying to test some other imap clients now. d!

[dovecot] Some experiences
by Amelia A.Lewis 06 Jan '03

06 Jan '03

Heyas ... I'm trying to use dovecot to set up a 'closed server' (actually, mixed) sort of environment, for a box to be deployed co-located. I wanted to talk about some of that, and see if some of my experience qualifies as 'bug'. Note that I'm notoriously verbose, so if that bothers you, read no further .... Since it's a more-or-less closed server, I didn't want to use pam (well, I wouldn't mind, for users with shell accounts, but I can't see a way to mix pam and passwd-file ... is there a way to do that?). It turns out that digest-md5 support for clients is, well, not very widespread. I expect this box to be used by various windoze clients, eventually, and while I'm willing to lay down the law a little, I can't find enough digest-md5 support to lay down that law. So, regretfully, I abandoned that plan. This kinda bothers me, since I think TLS/STARTTLS is absolutely the *wrong* solution for mailbox access (or for anything that deals with a store-and-forward transport). I therefore tried md5 passwords in a passwd-file, with STARTTLS enabled. Didn't work. I turned off SSL, and reenabled plain-text, and watched the login go by. Very sniffable, of course. But correct username and password ... failed. There are instructions for creating digest-md5 style secrets in auth.txt, but none for md5 passwords; I used openssl passwd -1 [password] (and cut and paste). It seems odd to me that this didn't work; does that command use a different algorithm than dovecot? Falling back ... since it *shouldn't* matter if the passwords are weak, as long as they're inside TLS (along with the entire rest of the transaction, ugh), I used mkpasswd to generate a standard unix passwd (and cut and paste). This worked. It worked with TLS, and it worked without (as long as I remembered to allow sniffable logins). One more oddity: I originally had a realm in the passwd-file, which also established the mail location and 'home' directory (most of the users can't actually log in and don't have accounts in /etc/passwd, so it's not a real home directory). There was an odd message in syslog, approximately like so (where 'user' represents the username, and 'domain.realm' represents both my domain name and the realm in the passwd-file): imap(user:@omain.realm): Failed to create storage with data: domain.realm Note the missing first letter after user:@ And I don't know what it was trying to do; the maildirs already exist. /etc/dovecot.conf sets the default mail location to /home/users/%n/Maildir (non-shell users are all inside /home/users; shell users have mail there, with symlinks to ~/Maildir); the passwd-file establishes the location of the INBOX pretty definitively, I would think. The solution was to remove the realm (which isn't useful except for digest md5, anway, right?). Hey, it's working! Wahoo! *laugh* Anyway, if someone can offer suggestions on what's up with the pieces that *aren't* working, I'd be interested to know. It might give me a greater range of options. Amy! -- Amelia A.

[dovecot] maildirmake, shared folders
by Amelia A.Lewis 03 Jan '03

03 Jan '03

Does dovecot support shared folders, maildir style? I've set it up, using the maildirmake from debian maildrop to create folders. I have a number of as-yet unresolved issues, so I haven't been able to test with many clients. It's interesting that dovecot manages to present folders as siblings (rather than children) of INBOX. But mutt, at least, doesn't seem to see the shared maildir (created per instructions in the maildirmake man page). I find in the debian archives that courier is unable to see messages delivered to new in a shared maildir. This doesn't seem to be the same set of symptoms, though. It appears, instead, that dovecot isn't recognizing (and then advertising) the shared-maildirs file (a text file that describes the name and the location). Is that the case? I don't think it's a high priority, mind, just wondering. Another question: can the dovecot distribution include a maildirmake utility? The documentation is pretty blunt about the significant advantages of maildirs, but one has to go to the courier distribution to find a utility to pre-create these (which dovecot seems to want, since it's recognizing the mail type by looking for the dir). This is most significant when setting up new users, of course. Possibly this is inappropriate, and I should instead ask the debian package maintainer to 'recommend' or 'suggest' the maildrop package in order to get the required utility. Nice stuff, though. I really like the ease of administration; dovecot looks to me like a sort of equivalent to postfix, for IMAP instead of SMTP. A request for the website: perhaps developers could supply information on clients used with the server, and what oddities are encountered? I know that IMAP client support is spotty, at best (for instance, I can't find a client that can do digest-md5; mutt is supposedly capable, but my installation doesn't even admit that that's a valid authenticator). This is partly significant because setting up a system that uses options for which there is little or no client support is, perhaps, an exercise in futility. Amy! -- Amelia A.

Code that looks unsafe contains @UNSAFE tag to make auditing easier. + Support for SORT extension. Originally I thought about not implementing any extensions before 1.0, but too many people want webmails which want SORT. THREAD is another extension which they want, but we don't support it yet. + imap_listen and imaps_listen settings now accept "*" and "::" to specify if we want to listen in IPv4 or IPv6 addresses. "::" may also listen in all IPv4 addresses depending on the OS (Linux does, BSD doesn't) + New setting: default_mail_env can be used to specify where to find users mailbox. Default is still to use autodetection. + New setting: imap_log_path to log logins etc. informational messages to different file. + We support now separate mbox file for INBOX folder, no need for symlink kludging anymore. + Support for keeping index files in different location than actual mailboxes. ? Disabled mailbox_check_interval setting by default, it breaks Evolution. - SEARCH was still somewhat buggy, especially with laggy networks. Also body/header searches might have crashed or at least used memory too much - Deleting messages in the middle of mbox caused dovecot to reindex the following messages as new messages (ie. change UIDs and set \Recent flag). - Digest-MD5 auth: Initial server challenge packet was missing a comma, which might have made it incompatible with some implementations. - Some more fixes to unnecessarily high memory usage - SELECT and EXAMINE often printed UNSEEN reply or maybe complained about corrupted indexes. Happened usually only with mbox. - FETCH BODYSTRUCTURE gave incorrect reply, breaking pine - LIST was pretty buggy with mbox subfolders - CHECK command returned just "missing parameters" error - DELETE didn't work with mbox folders - CREATE mailbox<hierarchy separator> failed always. - CREATE and RENAME didn't create required hierarchies with mbox - RFC822 date parser didn't handle single digit days correctly. - login_process_per_connection = yes didn't work with imaps port connections which is exactly where it was mostly wanted. - ssl_disabled = yes didn't disable listening in imaps port - process limiting code didn't compile everywhere (eg. FreeBSD). - Linux sendfile() was never detected - We didn't work at all with gcc/PowerPC

The folder > itself shows up but no mail. Oh, I think then you're just using mutt a bit wrong :) Enter-key goes inside a subfolder, space-key selects the folder. 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

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.

[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] o.99rc2 works on PowerPC - sort of...

Hi all, The new release starts on PowerPC now. On to the next problem... :-) When accessing my folders through Pine (setup to always go through IMAP, even local mboxes) I get "kicked out" it seems, pretty often. Here's what shows in the logfile: imap(jonas): file imap-bodystructure.c: line 342 (part_write_body): assertion failed: (part->children->next == NULL) - Jonas -- Debian GNU/Linux developer http://www.debian.org/ Jonas Smedegaard +45 40843136 http://dr.jones.dk/ Consulting for machines and humans: Spiff ApS
