[Dovecot] Dovecot, Squirrelmail and KMail
by Rob Thyssen 24 Jul '03

24 Jul '03

I just installed Dovecot and squirrelmail to read my email when I'm away from home. I subscribed to all the folders in my mail directory but I can't actually see any email. Is this a dovecot issue or a squirrelmail issue? I'm running KMail from KDE 3.1.2 and use Debian (Testing) on a Digital Alpha and installed both squirrelmail and dovecot using apt-get. I had to set 'default_mail_env = maildir:~/Mail' To get it to see the parent folders but I'm stuck there. Any advice appreciated. /rob

One way is to set default_realm and set the @domain for all users in passdb/userdb. Another way is to patch the code. Below is a patch for plaintext authentication. Or maybe I should make option that if given realm is default_realm, it would look up the user without the realm. I'm not sure if it's worth doing though. BTW.

Hi Grahame, > Hi all, > > I'm interested in implementing an anti-spam system using > bayesian filtering. I had the idea of modifying and IMAP > server to assist in training the spam filter. Why do you want to hook it up into your imap server? I think it would be better to prevent emails to enter the mailbox with the MTA rather than removing it when the user is reading his email using imap. Why? Because the spam that is in the mailbox might push the user over his quota limit, and thus preventing legitimate emails to be delivered. > I was thinking of running a program whenever a message in > moved to the folder "Spam" or to a "Safe" folder.

With the new API code that Timo is making now, I guess this would be possible.

You can always build a plugin, and plugins can be loaded whenever an administrator wants them to load. I don't know if Timo wants to include all plugins that are / will be written for dovecot, but I guess there might be a plugins part, where people can "post" their plugins so other people can benefit from them :) > Cheers > Grahame Kind regards, Maikel Verheijen

[Dovecot] Courier's IMAP custom flags implementation
by Timo Sirainen 23 Jul '03

23 Jul '03

Just thought to mention: http://dovecot.procontrol.fi/tmp/README.imapkeywords.html I'm not sure what to think of it. Good thing in it is that it doesn't limit the number of flags. Bad thing is that I think it's way too slow. Compared to Dovecot's implementation where I "steal" maildir flags a..z and treat them in the normal maildir way. Bad thing is obviously that it's limited to 26 different flags. And I really should fix that customflags file soon to be NFS-safe / read-lockless. It's just a bit problematic how to handle removing unused flags when you've hit the 26 limit and try to add new ones.

[Dovecot] Hooks on folder operations
by Grahame Bowland 23 Jul '03

23 Jul '03

Hi all, I'm interested in implementing an anti-spam system using bayesian filtering. I had the idea of modifying and IMAP server to assist in training the spam filter. I was thinking of running a program whenever a message in moved to the folder "Spam" or to a "Safe" folder. This could be easily added to the server as a generic feature, with hook programs for: * new message in a folder (either new, or moved into the folder) * message in folder is modified * message in folder is removed and so on. If the support was generic enough there could be many uses for it. Security of the external program needs to be considered but doesn't really affect the IMAP server itself. Anyway, if I were to write a patch to add support for running an external program in these cases, would it be included? Any feedback would be appreciated, if I'm going to do this I might as well do it in a way that can be integrated back into the main tree!

[Dovecot] Imap 2 imap copy tool?
by Maikel Verheijen 23 Jul '03

23 Jul '03

Hi List! At the moment, our company is preparing to migrate from MS-Exchange to a dovecot mail platform. Since there is no way to access the emails on the file-store other than using webmail, pop or imap, I wanted to do this by using an imap-to-imap copy tool. I have found one that does the job (but POORLY), named migrate (http://prdownloads.sourceforge.net/cyrus-utils/) Does anyone know some other tool(s) for me I could have a look at? My requirements for such software are: - it should use a username;password list to do the migration (20k+ users) - it should be able to do imap to imap copy, or imap to maildir with a flexible path - it should copy all the folders too, except the "Public Folders" from exchange. - it has to be able to "ignore" unknown flags from the exchange imap server (\Recent). What I would love the software to have (and what imapmigrate lacks): - Folder and message syncing (to be able to keep the mailbox in sync) - detailed errors if something goes wrong, not too much fuss over accounts that DO get copied cleanly - fast tool? :) Thank you for your time! Kind regards, Maikel Verheijen.

[Dovecot] hierarchy_sep
by molter＠tin.it 22 Jul '03

22 Jul '03

Hi Timo, I would like to add another naming scheme to dovecot to recognize maildir folders: As of today: ~/Maildir/.foo ~/Maildir/.foo.bar I would like to add: ~/Maildir/foo ~/Maildir/foo/bar I had a quick look at the code (very clean, I am impressed!) and I saw struct mail_storage, with field hierarchy_sep. I think I cannot just set hierarchy_sep to '/', because /foo would start from the root of the filesystem instead of being relative to ~/Maildir. Do you have any suggestions on the cleaner way of doing it? Or maybe do you think it is wrong to depart from '.' for some reason? thanks Marco

Hi Timo, [snipped possible scenario's] > OK. 3) is the best idea :) But it requires a few changes to > make it work. I wouldn't expect it to work out of the box :) But if I read your suggestions right, you propose a "fixed" change in the maildir functions that call the quota update functions if necessary. So perhaps we should make a quota_enabled = yes|no flag int the config file, and use that? I would still be trying to make the quota update functions for you, and try to put them in. > Actually, I think this is exactly how I want quota and ACLs > to be implemented. No extra interface changes for either one of them. > > For quota, you'd want to do something like: > > expunge(): nothing special, just update the quota file after expunges Expunge should recalculate the whole mailfolder? > save_next(): Check data istream's size and if it's over quota, fail. Ok. So this one can be "easy". Just check if mailsize + current usage < max_quota. :) > copy(): this is somewhat problematic, if there wasn't the > maildir hardlinks you wouldn't have to touch it at all.. A copy can duplicate a message in the same store, but do hardlinks work on nfs? If not, we should add the message to the quota list. And maybe we should just add size of the email anyway, it won't be that much of a loss to the user, and it would save us a lot of checking. :) And how about a user that has no quota file (yet), can we "recreate" them? Maybe do a quota lookup for the user (database or file)? This can be done using a module I guess, so it could be "user configurable". Regards, Maikel Verheijen.

[Dovecot] migrating from uw imapd
by Craig 21 Jul '03

21 Jul '03

Hi, I'm trying to migrate from uw imapd to dovecot. I'm having two problems at the moment. 1. uw imapd grabs new mail from /var/mail/user and then shoves it into ~/mbox, is there any way to make dovecot handle this kind of setup or am I better off merging ~/mbox back into /var/mail/user? If merging is better are what tools are best for this? 2. While I did have have everything in ~/Mail coming up dovetail stopped working and logs the following error: syslog:Jul 19 23:01:07 epsilon3 imap-login: Login: haakon [192.168.0.107] syslog:Jul 19 23:01:07 epsilon3 imap(haakon): Failed to create storage with data: ~/Mail/:INBOX=/var/mail/haakon syslog:Jul 19 23:01:07 epsilon3 dovecot: child 10417 (imap) returned error 89 any idea what is causing this?

Hi List! I read a post about moving a .mailbixlist to a .subscriptionfile when a user did not have one, but did have a .mailboxlist file.

My question is: - Where and how does dovecot call this function? - Would it be easy to use a module to a) create a mailpath (can be done as the mailuser's id, I use one uid, and my path is all owned by that uid), and b) simply remove a quota file?

[Dovecot] Dovecot on Linux 2.6.0-test1-ac1
by Grahame Bowland 16 Jul '03

16 Jul '03

Hi all For various reasons I was looking into 2.6, so I installed a copy on my desktop. Everything works fine, except for dovecot - errors such as this appeared in the syslog: Jul 15 14:41:09 typhaon dovecot: Dovecot starting up Jul 15 14:41:12 typhaon imap-login: setuid(113) failed: Resource temporarily unavailable Jul 15 14:41:12 typhaon dovecot: Login process died too early - shutting down I can imagine why setuid() should ever fail, I've confirmed that the daemon is running as UID zero at the time it makes the call. However, the call succeeds if I comment out: restrict_process_size((unsigned int)-1, 1); on line 134 of src/login-common/main.c it starts to work again. It's very strange - I got the idea to try this from the list archives. I'm willing to track this down if anyone can suggest possible things in restrict_process_size() that might be causing this failure. All the other daemons that I run that need to drop root privileges work fine..

[Dovecot] Indexes again
by Timo Sirainen 16 Jul '03

16 Jul '03

A bit quiet here, so here's some more thoughts about indexes. Even though I was thinking only how to make them usable with NFS (I wrote it to doc/nfs.txt), it then occured to me that exactly the same tricks would help with local filesystem indexes as well. Especially the lockless reading would help with lock contention issues I was worrying about earlier with shared mailboxes. Also it occured to me that keeping maildir filenames fully synchronized in index file probably isn't very good idea from performance point of view.. BTW. I almost committed the .tree removal code to CVS today. Then I noticed that expunging ignores about half of the deleted messages. This could have been actually happening with the old code in some situations as well, although it probably would have skipped only a couple of messages. Anyway, fixing this properly takes some more time.. -------- Ideas how to make indexes work pretty well with NFS: Reading shouldn't require locks, so modifying should be done using only atomic operations. These include: - Replacing the file completely using rename() - We probably can't assume that writing more than one byte at a time is atomic. If we have to modify a larger dataset, we could do: - struct { bit_t use_first; dataset_t first; dataset_t second; } - when reading, we use first if use_first is set, second if it's unset - when writing, we first write to the non-used variable, only then we update the flag. - This of course requires twice the amount of space for dataset plus one extra bit, so it shouldn't be used too much - If data can be only set, but never changed, we need only one extra bit to specify if the data is set. - Appending new data to end of file. We'd have to have used_file_size variable in header, done like described above. - Each cached message record would have a pointer to next part, so more cached data could be appended to file. Message flags are the most commonly modified data. If we just modify them directly, a simultaneous read might catch the change only partially. But luckily for us, this is accepted behaviour so we can do it. Another commonly modified data is maildir filenames. We probably want to store only the base name in index and keep the full name synchronized only locally. Compressing unused data from index files would have to be done by rewriting the index into index.lock file and renaming it over the index file. All file operations should probably be done with lseek(), read() and write() to avoid extra network traffic. There should be some clever read-ahead caching however.

If someone's interested, here's an explanation and test code how I was planning on replacing the current .imap.index.tree file's functionality. The .tree file will be removed so you'll save some disk/memory as well, something like 5-20% of whole indexes.

[Dovecot] CVS state
by Timo Sirainen 13 Jul '03

13 Jul '03

Just a small note that if you upgrade to latest CVS, you'll have to delete old index files or you'll probably get wrong BODY or BODYSTRUCTURE replies. Next release will have index file's version number increased so it will automatically rebuild them when needed. I didn't raise it yet since several other changes are likely to come soon.

[Dovecot] Permission denied
by Jaime Medrano 12 Jul '03

12 Jul '03

Dovecot is faulting on an error about permissions that it shouldn't do. I've got an user with its home dir with permissions 700, and inside the mail directory with the mboxes. In the error log I can see: 'Can't chdir to /home/user. Permission denied' I wonder why it has to chdir to that directory and why it can't access. Shouldn't it be running as the user?

[Dovecot] FreeBSD /etc/passwd errors
by James Read 12 Jul '03

12 Jul '03

Hi there, I've currently compiled and running dovecot version 0.99.10 on my FreeBSD 4.8 system from the ports and am having problems with authenticating clients with the imap/pop3 service. The error message i get is: Jul 11 19:26:18 dev dovecot: Dovecot starting up Jul 11 19:27:23 dev dovecot-auth: passwd(james): invalid password field '*' Jul 11 19:27:23 dev imap-login: Disconnected [10.0.0.1] On the client system I am using Outlook Express 6 and the password dialog box keeps on comming up. Im sure its somthing to do with my conf file not being configured right, here are the main bits: default_mail_env = mbox:/var/mail/%u client_workarounds = oe6-fetch-no-newmail outlook-idle auth = default auth_userdb = passwd auth_passdb = passwd auth_user = dovecot-auth auth_username_chars = If its somthing simple please point me in the right direction as I feel increadbly dumb because im sure its something to do with the passwd file but just carnt get pass the last hurdle! Many thanks in advanced. James.

[Dovecot] Configuration file changes in CVS
by Timo Sirainen 12 Jul '03

12 Jul '03

OK, it's there now. Not much tested yet, so there's probably some bugs. I didn't yet add support for templates, but I probably will later. The new format is like in the two example config files I sent before: http://dovecot.procontrol.fi/list/dovecot/2003-July/001832.html dovecot-example.conf contains the simple configuration now. New code also tries to be backwards compatible with most settings. New code will also try to check that the configuration is valid after SIGHUP before actually using it, so the server won't die anymore if you made a typo somewhere. It doesn't check all the settings though. Namespace configuration comes probably next. Something like: namespace { prefix = INBOX type = private separator = / location = mbox:/var/mail/%u } namespace { prefix = type = private separator = . location = maildir:~/ } namespace { prefix = lists/ type = public separator = / location = mbox:/var/mail/lists/archives }

[Dovecot] Date sort-order ignoring timezone, and a few Q's.
by Stuart Henderson 11 Jul '03

11 Jul '03

Timo, thanks for writing and releasing Dovecot. I've recently discovered it and have been very impressed at the speed and balance between flexibility and simplicity. I had to make a packet-trace to be sure that encryption with OpenSSL was working correctly, since it all 'just worked' first time without complex configuration, which I don't think I've ever seen before ;-) LDAP too was quite straightforward (after I worked out where my virtual-domain schema differed from what was required). One small glitch I have noticed is that when the client requests a list of messages sorted by date, the timezone is ignored. For example, listed in descending order: 07/07/2003 00:01 +0300 (= 21:01 UT) 06/07/2003 23:15 +0100 (= 22:15 UT) 06/07/2003 19:03 +0100 (= 18:03 UT) I think that this should instead be... 06/07/2003 23:15 +0100 (= 22:15 UT) 07/07/2003 00:01 +0300 (= 21:01 UT) 06/07/2003 19:03 +0100 (= 18:03 UT) It's most noticable when the client (Mulberry in my case) is configured to display all times in the local timezone. (Mulberry has recently added custom flags which work perfectly with Dovecot - I was hoping this would be the case, and was one of the reasons I was looking for something to replace the version of Courier I previously had installed). Mulberry does like to have NAMESPACE otherwise it usually asks for folder locations on connecting, btw. No real problem, though. A little tip: if anyone is interested in having their MDA write Maildir with CR+LF so that sendfile(2) can be used on all messages (not just those created by Dovecot), Exim offers this natively by adding the "use_crlf" option to the appendfile transport which seems to work fine with 0.99.10 (though not 0.99.9.1, maybe because of 2003-06-04 17:39 in Changelog). It seems Dovecot is using the ,W= Maildir tag for some type of size instead of ,S= but I haven't traced far enough to work out what exactly W/virtual_size means, am I right in guessing that it might be 'wire size' i.e. message-size-with-CRLF-line-endings? (If so, use_crlf in exim.conf can be augmented with "maildir_tag = ,W=$message_size" to help keep overheads to a minimum). And, one final question: for a dual-stack machine to listen on both IPv6 and IPv4 sockets, is the currently preferred option simply to start two instances of Dovecot with their own dovecot.conf containing different *_listen parameters? --Stu

[Dovecot] Concerns switching from Courier to Dovecot
by marcotte＠panix.com 10 Jul '03

10 Jul '03

[ I'm posting this again since I wasn't subscribed to the list when I first posted. I'm sorry if this gets posted twice] I was considering replacing Courier-IMAP with dovecot in the future, but have some concerns. I realize that some things simply haven't been finished yet like quotas, but some other things may prevent me from using dovecot as a drop in replacement in the future. Subfolders have different names in the file system. A folder (INBOX.subfolder) is named ".subfolder" in Courier, but "INBOX.subfolder" in dovecot. I can't simply rename all the subfolders, because our customers have direct access to the maildirs, and write to it directly with procmail and mail clients like mutt. Certain files have different names, but contain the same information. For example, the subscription lists and UID files look the same to me but have different names. I suppose they could be converted, but this would make it difficult to run both IMAP servers side-by-side, which I'd like to do until dovecot has all the features I need. I also heard talk of the hierarchy separator being changed from "." to "/". Now, is it possible configuration options could be added to allow for better Courier compatibility? I would be willing to help with this. Thanks! -- - Brian

There is no problem to have two instances running, though it might be more admin-friendly to allow the listen addresses to be supplied on the command-line, since it would save maintaining a second config file (and I imagine this would be easier for you than changing the socket code), but this is quite a low priority I think.

[Dovecot] search throwing "Sequence out of range"
by Stuart Henderson 09 Jul '03

09 Jul '03

Mulberry client-side message filtering can be persuaded to search for a nonexistent message ... <tag> UID SEARCH UNSEEN UNDELETED UNDRAFT 12 (OR FROM "Cron Daemon <sthen(a)eeyore.37.spacehopper.org>" SUBJECT "Cron <sthen@wide> /home/sthen/pingme") Dovecot 0.99.10 returns this ... <tag> NO Sequence out of range: 12 I *think* the correct behaviour here is to return a null set of search results and avoid the error message in the client. i.e. * SEARCH <tag> OK Certainly this is how other servers seem to work, and my understanding of the next paragraph from IMAP4REV1 RFC seems to backs this up (though the wording in the RFC isn't 100% clear to me) "Message set ranges are permitted; however, there is no guarantee that unique identifiers be contiguous. A non-existent unique identifier within a message set range is ignored without any error message generated." it's not Mulberry's fault that it sent this immediately after deleting message 12, since on closer investigation this is exactly what my filter rules are asking it to do because I forgot to set "stop if matched", however it would be helpful to change sometime since I'm sure I'm not the only person to have done that (-: of course I've fixed my filters now, so it isn't a high priority for me.

[Dovecot] LDAP bind questions
by Jared 09 Jul '03

09 Jul '03

Hello, I've got dovecot set up to authenticate against our LDAP server. So far seems to work well. I have two concerns that I haven't been able to find answers for in the documentation or archives. Is there any intention to support "authentication binds" so you don't have to bind as a user with read privileges to everyone's userPassword attribute? For security purposes I'd like to see this functionality. And my next concern would become a non-issue if the above was supported, but is there a way to set the dnpass equal to a SSHA password? When I try setting it like this: dnpass = {SSHA}VhxqnmwCLVQj7g3rQV+g9F3XnaJ6bRXR in dovecot-ldap.conf It still tries to do a simple bind and fails. I get this error: dovecot-auth: LDAP: ldap_simple_bind_s() failed \ (dn cn=authadmin,ou=people,dc=domain,dc=com): Invalid credentials I'd prefer not to have the password for the authentication admin user stored in plain text in the conf file. Thanks, -jared

[Dovecot] Configuration file changes
by Timo Sirainen 02 Jul '03

I was going to add support for "configuration groups", but got a bit stuck at how the logic is supposed to work. I think there could be different settings based on IP/port it's listening in, or based on given username. I can't really describe how it would work, and I'm not entirely sure myself either :) Does this make sense: # (default settings here) # if auth groups are defined here, they are included in all groups below group 1.server.org { protocols = imap imaps pop3 pop3s ssl_cert_file = /etc/ssl/certs/server1.pem login_dir = /var/run/dovecot/login/server1 login { # common for imap/pop3 listen = 1.server.org } auth server1 { mechanisms = plain userdb = ldap /etc/ldap-server1.conf passdb = ldap /etc/ldap-server1.conf } group admins { mail_full_filesystem_access = yes auth admins { mechanisms = plain userdb = passwd-file /etc/admins.passwd passdb = passwd-file /etc/admins.passwd } } } # (any setting changes here would affect only new groups below, otherwise # the config file parsing would get difficult..) group anonymous { protocols = imap ssl_disable = yes login_dir = /var/run/dovecot/login/anonymous login { listen = anonymous.server.org process_per_connection = no processes_count = 1 } auth anonymous { mechanisms = plain anonymous userdb = passwd-file /etc/anon.passwd passdb = passwd-file /etc/anon.passwd } }

[Dovecot] Dovecot first impressions
by Matthias Andree 30 Jun '03

30 Jun '03

Hi, I have only recently become aware of Dovecot and gave it a try. The previous 0.99.9.1 version didn't work well for me (OpenSSL), I dropped it, but 0.99.10 has come just in time (saw it on freshmeat) and I thought I'd give it another try if it promised SSL fixes, and it's sorta working for me (i. e. it works with mutt, Mozilla, sylpheed, but not cone -- but cone is beta and has SSL issues with certificate verification, I seem to have hosed the setup). Anyways, I was delighted to see how quick it is to install an IMAP/POP3 server -- but being a Courier-IMAP user, I have some compatibility concerns, but these appear to be minor, and the daemontools <URL:http://cr.yp.to/daemontools.html> friendliness (dovecot -F) is very much to my taste as well. One deals with NAMESPACE -- it takes manual intervention in order to convince Mozilla of the new namespace and stuff. Courier-IMAP used to provide a NAMESPACE, but Mozilla leaves it unchanged if I point it to Dovecot. The other is the naming itself, easily visible from the LIST replies below: Courier prefixes everything with "INBOX" (which I believe is reflected in the NAMESPACE, but it appears as though most clients were only tested against UWIMAP). Apparently, mail user clients (particularly the Mozilla derivatives) do a better job of presenting Dovecot's layout, so this one has my preference, although it differs from Courier's and Cyrus 2.1's. Timo, could you add the NAMESPACE extension to Dovecot? That would be a great migration aid for people switching over from Courier-IMAP. Other than that, my first impression is a very good one. One question (I may have missed it in the docs): how do I properly create folders with national characters (umlauts) in their names? Apparently, Courier-IMAP and Dovecot just forward the file name verbatim when I type maildirmake -f t=E4=DFt Maildir, which doesn't look right. OTOH, I am well aware that the IMAP servers can't possible guess the character set, so it must be my "maildirmake" that is flawed rather than the server. This is Courier-IMAP: . namespace * NAMESPACE (("INBOX." ".")) NIL (("shared." ".")) . OK NAMESPACE completed. . list "" * * LIST (\HasNoChildren) "." "INBOX.INBOX.Trash" * LIST (\HasNoChildren) "."

[Dovecot] Message display corrupted or missing in Netscape 7.0 and Mozilla 1.3
by Steven Enderle 28 Jun '03

28 Jun '03

Hi, a few days ago, we switched our site from pop3 to imap. We are running about 20 users with Netscape 7.0 on a FreeBSD-4.8 Server . I installed dovecot 0.9.99.1 via the freebsd-ports collection, which was as easy as make install and start dovecot. Our users mailboxes are still standart mbox format in /var/mail/(user), as it is default in Freebsd. Now we suffer from a realy ugly problem, which was arising after the switch from pop3. When Netscape is newly started, it works fine as expected until Netscape displays messages corrupted or stops displaying them completly. I also cannot forward them in that state or open or delete them in any other way. The only way to get it working again is to quit Netscape, exit quickstart and restart Netscape again. It just hangs on a bunch of messages or all of them. The user notices it like this: There are three windows displayed in netscape mail: 1. imap folder view 2. message list of the current folder and 3. the currently displayed message. The Folder view and Message List in Netscape is always fine, so the Subject and sender, time, etc is always displayed in the List. The problem occurs then on some messages when i select them for reading. The Message Display below the message list just stays empty (also opening the message in a new window doesn't help) or the "title bar in the Message Display" stays empty (no subject, sender, time etc) and the raw email starting with header, raw html email and encoded attachment is shown below, each line followed by another blank line, like this: == start corrupted email X-UIDL: 8793f170f0430909 Return-Path: <frank.xx(a)xx.de> Delivered-To: xx(a)mdn.de Received: from mailrelay1.xx.de (mailrelay.xx.de [212.114.153.xx]) by xx.de (Postfix) with ESMTP id D31B7A88F for <xx(a)mdn.de>; Wed, 18 Jun 2003 08:55:07 +0200 (CEST) Received: from ntmail1.xx.de (ntmail1.xx.de [212.114.155.xx]) html and stuff following... == end corrupted email One could read it, but its realy ugly. It seems, that if i delete a lot of messages in sequence (the morning spam), i can force to happen that problem earlier. It always hangs while deleting my spam. I like dovecot a lot, it was easy to install etc and works pretty fine except that it still seems to be in beta-stage. Now i would switch to courier/uw-imap until dovecot is ready, but the mbox format dovecot is using seems to be pretty uniq? I think, the users could keep their /var/mail/Username-INBOX, but wouldn't they loose their email folders? Is there any way to switch the software in a easy way? Or will there be a near future release which will fix that? What about the cvs version? Thanks for you help!

[Dovecot] 0.99.10 released
by Timo Sirainen 27 Jun '03

27 Jun '03

No bug reports since rc4, so here it is. v0.99.10 2003-06-26 Timo Sirainen <tss(a)iki.fi> * Default PAM service name changed to "dovecot". This means that if you're using PAM, you most likely have to do mv /etc/pam.d/imap /etc/pam.d/dovecot If you wish to keep using imap, see doc/auth.txt. * ~/rawlog directory changed to ~/dovecot.rawlog + Faster and better maildir synchronization. We support read-only maildirs and out-of-quota conditions are handled a lot better. dovecot-uidlist file still isn't out-of-quota-safe though, but you can keep it in another location where quota isn't checked. For example: default_mail_env = Maildir:~/Maildir: INDEX=/noquota/%u:CONTROL=/noquota/%u + Read-only mboxes are supported now. + Only NOOP and CHECK now always do a mailbox sync checking. Other commands sync max. once in 5 seconds, plus always from indexes. This should reduce I/O a bit. + All NUL characters are translated to ascii #128 before sending to client. RFC prohibits sending NULs and this is how UW-IMAP handles it as well. + Make ENVELOPE, BODY and BODYSTRUCTURE replies more compact by removing multiple LWSPs and translating TABs to spaces. RFC doesn't specifically require this, but this seems to be the wanted behaviour.. + Added ANONYMOUS SASL mechanism. + More flexible user chrooting configuration in home directories: "<chroot>/./<homedir>" + Added support for dynamically loadable IMAP/POP3 modules. See INSTALL file for more information. - Partial fetches were broken if mails had CR+LF linefeeds - SEARCH DELETED didn't return anything if all messages were deleted - OpenSSL support was broken in many installations because we were chrooted and it couldn't open /dev/urandom. - PAM: Giving wrong password blocked the whole process for two seconds. Now we create a new process for each check. - Lots of other smaller bugfixes and better error handling

[Dovecot] Dovecot and file permissions
by Spectron International, Inc. 26 Jun '03

26 Jun '03

I have some questions about some parameters in dovecot.conf, I have them configured as this: # User to use for the login process. The user must belong to a group where # only it has access, it's used to control access for authentication process # named sockets login_user=postfix # User to use for the process. Only shadow and pam authentication requires # roots, so use something else if possible auth_user=postfix It seems to me that all files created and used by Dovecot as long as they were created by the postfix user, they would be accesible. Right? My maildir shows as this: drw------- 6 postfix postdrop 65 Jun 26 09:40 Maildir so I guess postfix has full access to the maildir. Wouldn't setting login_user and auth_user to postfix let Dovecot access the Maildir? In the logs I get permission errors, if I chmod to 777 it works ok. This is what I get in the logs: Jun 26 09:24:23 backup imap(f_rojas): opendir(/opt/mail/f_rojas/Maildir) failed: Permission denied Jun 26 09:24:31 backup imap(f_rojas): stat(/opt/mail/f_rojas/Maildir/.Drafts) failed: Permission denied Jun 26 09:24:31 backup imap(f_rojas): lstat(/opt/mail/f_rojas/Maildir/cur) failed: Permission denied Jun 26 09:24:31 backup imap(f_rojas): stat(/opt/mail/f_rojas/Maildir/.Sent Items) failed: Permission denied Jun 26 09:24:31 backup imap(f_rojas): lstat(/opt/mail/f_rojas/Maildir/cur) failed: Permission denied Jun 26 09:26:52 backup imap(f_rojas): lstat(/opt/mail/f_rojas/Maildir/cur) failed: Permission denied Jun 26 10:06:09 backup imap(f_rojas): lstat(/opt/mail/f_rojas/Maildir/cur) failed: Permission denied Jun 26 10:06:15 backup imap(f_rojas): opendir(/opt/mail/f_rojas/Maildir) failed: Permission denied Jun 26 10:08:38 backup imap(f_rojas): opendir(/opt/mail/f_rojas/Maildir) failed: Permission denied Jun 26 10:13:03 backup imap(f_rojas): stat(/opt/mail/f_rojas/Maildir/.Sent Items) failed: Permission denied Faw

[Dovecot] mutt and dovecot
by Charlie Allom 26 Jun '03

26 Jun '03

Hi, I setup squirrelmail with dovecot and everything worked. I moved users Maildir directores to ~/Maildir/INBOX.directory/ and updated the .subscriptions file to something like ^INBOX.directory squirrelmail picks this up, but I can't seem to get mutt to read this style. In fact I would have assumed that dovecot would read ~/Maildir/ as INBOX and everything under it as it stands, without having to shuffle things about. Does anyone use mutt and have any words fo advice? I am not sure that courier-imapd does this sort of munging?

[Dovecot] Bug? Folder tree confusion
by Dominic Marks 25 Jun '03

25 Jun '03

Can anyone else confirm this behaviour: o Open an IMAP mailbox o Make a new folder (foo/) o Make another new folder under foo (foo/bar) o Delete foo o Bar will go away and foo will remain (Outlook bug ?) o Try and delete foo, you won't be able to because Dovecot thinks foo is not empty and Outlook thinks it is. This is using Dovecot 0.99.10-rc2 and MS Outlook 2000. Don't know if a bug lies within here somewhere (not nessarily in Dovecot), just something I noticed while playing around. Thanks, -- Dominic <dom at cus.org.uk> <dominic.marks at npl.co.uk>

[Dovecot] Bug? High CPU Usage after nessus scan
by Jens Gutzeit 25 Jun '03

25 Jun '03

Hi all, I think I've found a Bug in current rc2 (same occours with rc1 and 0.99.9.1). I'am running dovecot with imap, pop3 and the ssl equivalents, after a nessus scan of my host with Bruteforce checks on IMAP, imap-login eats up lots of cpu. Before the scan: dovecot 22342 0.0 0.1 2320 636 ? SN Jun18 0:00 imap-login dovecot 5841 0.0 0.1 2320 692 ? SN Jun21 0:00 imap-login dovecot 5852 0.0 0.1 2320 692 ? SN Jun21 0:00 imap-login Looks wonderfull ;) After the scan: dovecot 20059 39.5 0.2 2340 820 ? RN 20:02 14:08 imap-login dovecot 20733 0.0 0.2 2320 804 ?

SN 20:04 0:00 imap-login This was on my local test machine, the same occours on a production machine, both are running Debian GNU/Linux woody, one with Openssl and one with GNUTLS. Even 2 hours after the scan the CPU Usage is so high, I don't think this is normal behaviour? The logs didn't say anything during the test. If you need more information please tell me what data you need and I look for it. -- Best regards/freundliche Grüße Jens Gutzeit http://www.gutzeit.at

[Dovecot] 0.99.10-rc1
by Timo Sirainen 23 Jun '03

23 Jun '03

Home again. Fixed SSL checking for Redhat 9, I hope. Could someone test if it actually works now? Also fixed a few compiler warnings. If this thing works, I'll just update the NEWS file and call it 0.99.10. http://dovecot.procontrol.fi/rc/ Near future plans include rewriting parts of index handling. At least .tree file will go, I've a _much_ better idea how to replace it. .data file is also too bloaty and it's a bit difficult to add new fields into it. I'd have to figure out some better API to access it. I've also been worrying about locking.. If we want to share indexes between many clients, lock contention will become a problem. For example a "FETCH 1:* BODY[]" could take a long time and index can't be modified while it's being done. I'm not really sure what to do about this.. Probably some more fine graned locking and maybe some kind of transaction log where changes are written if you couldn't get exclusive lock.

Hi, Been using Dovecot for a few weeks now, must say it's very good.. I've been looking for a 'drop in' replacement for UWImap for ages! :) but just recently It's been giving me a few problem, I haven't tracked down exactly what causes the problem yet (I'm using Apple Mail on OS X 10.2.6) but after a good mail session it keep trying to log in over and over again..

[Dovecot] \0\n at end of lines
by Mike Grupenhoff 19 Jun '03

19 Jun '03

Since upgrading to -test11, mail fetched from imap has every line terminated with a nul and a newline ("\0\n"). This also happens with -test12. It seems to happen with both mbox and maildir. I'm running on NetBSD/sparc (NetBSD-current as of April 1, 1.6Q). If it matters, I have "mail_save_crlf" set to "no" and "mail_read_mmaped" also set to "no". I can't find any other options that look like they could be relevant. Any ideas? Thanks, mike

[Dovecot] 0.99.10-test12
by Timo Sirainen 19 Jun '03

19 Jun '03

http://dovecot.procontrol.fi/test/ I should have released 0.99.10 already I think.. There's just two annoying problems that I think should be fixed first: - PAM: If user gives a wrong password, dovecot-auth process sleeps for two seconds, blocking everyone else who are trying to authenticate at the time. So using PAM isn't very good idea at the moment. - OpenSSL problems. Are they really my fault? I have no idea what I could be doing wrong. Maybe some compile option is wrong? Also I should try to use pkg-config to get compile flags if it exists in configure. The new things in -test12 then: - We sync mailbox less often. Only NOOP and CHECK will force a mailbox sync now. Other commands do it also but only if mailbox hasn't been synced in last 5 seconds. Maybe this reduces some I/O. At least a bit less stat() calls :) - Dirty maildir flag flushing work now. Meaning that if you change message flags but rename() fails because you're out of quota, the flags are changed in index file and dirty-flag is set. Once in a while it tries to flush the dirty flags by rename()ing the file again. - IMAP RFC requires that NUL characters are never sent to client. We do now the same as UW-IMAP by sending ascii 128 chars instead.

http://dovecot.procontrol.fi/test/ - Hopefully OpenSSL is fixed :) - We sometimes produced invalid ENVELOPE with 8bit headers. That could really have broken things (broke it in test12). So, what's left is to make PAM work well..

[Dovecot] SASL Support

I need to support Outlook/Outlook Express users of Sendmail with SMTP Authorization. From what I can see, the LOGIN method available in Outlook/Outlook Express is the only applicable way to go at this time. It appears it is not supported in Dovecot right now. Is this correct and, if so, how would I go about adding this support?

[Dovecot] Dovecot will not run on secure kernel.
by Ola Garstad 16 Jun '03

16 Jun '03

I am trying to run Dovecot on RH 7.3 with Linux kernel 2.4.20 + GrSecurity patch. I downloaded the RPM yesterday and installed it. When I start Dovecot the kernel reports: kernel: grsec: From 192.168.1.22: attempt to overstep process limit by (dovecot:14491) UID(0) EUID(0), parent (dovecot:23872) UID(0) EUID(0) I have never seen this problem in the 3 years I have used GrSecurity together with a lot of programs. GrSecurity explains: "Enforce RLIMIT_NPROC on execs. Users with a resource limit on processes will have the value checked during execve() calls. The current system only checks the system limit during fork() calls." Any ideas why Dovecot causes this problem? -- Ola

[Dovecot] Deleting NFS-mounted Maildir subfolders fails
by Christian Ehrhardt 14 Jun '03

14 Jun '03

Hi, [ please CC me on replies, I'm not subscribed to the list ] I'm using dovecot-99.9.1 with a little hack to get authentication to work the way we want it. The server is running on a Solaris 9 host and user homes are mounted via NFS from a Solaris 8 server (Version doesn't seem to matter). Almost everything's fine but I can't delete maildir subfolders if these reside on a non local NFS-directory. The reason given is that the directory isn't empty and hence can't be deleted. Most likely the following happens: dovecot has the index file and other stuff in the maildir subfolder opened via NFS. When the delete request comes in dovecot deletes these files but doesn't close them. On normal unix file systems this is no Problem but with Solaris NFS these file's aren't actually deleted until they are (explicitly or implicitly) closed. Instead they are renamed to .nfs.<some digits>. These files will automatically vanish once they are closed. However, as long as they exist it is impossible to delete the directory where these files reside and rmdir fails. This is not a big deal and one may argue that dovecot is fine and the NFS implementation is in error. However, it would be cool if dovecot could atttempt to close all administrative files before it deletes them (or at least before it tries to delete the directory where these files reside). regards Christian Ehrhardt -- THAT'S ALL FOLKS!

[Dovecot] Speed and memory probs writing large Maildir
by Robin Whittle 14 Jun '03

14 Jun '03

I have Dovecot 0.99.9.1 compiled from the source, without SSL, running on a Red Hat 9.0 system - EXT3 file system, Pentium Pro 233 MHz, Intel motherboard, 128M RAM, IBM 40Gig 7200 RPM HD. I find reading and searching to be nice and fast, and comparing it with Courier IMAP on a Celeron 824 MHz, I think Dovecot is generally not much slower, which means it may well be faster than Courier in some or many ways if it was running on the same machine. My only problem is when writing mailboxes with large numbers of messages. I use Mailir - the same arrangement as Courier IMAP. (I also find that Netscape 4.77 can't use mailboxes which are subfolders of others, but that is probably a Netscape config problem.) I am using Netscape 4.77 (Windows 2000 1.3 GHz Celeron, via 100Mbps switched Ethernet to the Linux machines) to do these tests since I find Netscape 7.02 to be much slower. Netscape 7.02 seems to want to resynch its notion of the mailbox repeatedly as it is writing to it. Without looking at the IMAP traffic (I don't know how) I would say that Netscape 4.77 is not doing this at all. Indeed, after the write, looking at the mailbox causes Netscape 4.77 to read the headers from the IMAP server - so I feel sure that its way of writing the messages is purely "write". Writing a mailbox with a small number of large messages, such as 20 x 100k messages is fine. There is no obvious speed problem or excessive memory use. When writing 2000 x 1k messages, it is totally different. Here are some times for writing from a Netscape 4.77 local mailbox to Dovecot and to Courier IMAP. Message Total Time CPU max Memory RSS size number size Seconds Approx Megs - max Dovecot 100k 100 10M 23 15% ~2 100k 20 2M ~5 ? 1.2 10k 200 2M 20 15% 4 ! 1k 2000 2M 230 60 32 !!!! Courier IMAP 100k 100 10M 14 5% ~1 100k 20 2M ~2 ? ? 10k 200 2M 9 5% ~0.6 1k 2000 2M 88 2% ~0.6 This 2000 message test is small compared to some of the mailboxes I have. I used a real-live mailbox, 6878 messages - 44 Megabytes in a single Mbox for a more demanding test. Using Netscape 4.77 to copy this to a Dovecot Maildir took a very long time - over 30 minutes. The process was fast at first and got slower and slower. As the number of messages in the destination Maildir increased, the memory usage went up and the speed reduced. It seems that RSS memory usage (as reported by "top -d 0.3" hit some kind of limit at about 49 Megs after 4000 messages and then went down a little to about 48 or less. CPU usage was 30 to 82%, fluctuating according to the moment top looked. At the end, I think it was only writing 1.5 messages a second. RSS is the "total amount of physical memory used by the task". The "SIZE" was even bigger - "code plus data plus stack". This got up to 114 Megs by the end of the writing process! After the write had finished, I made Netscape 4.77 view the destination mailbox. This caused Dovecot to send it all the headers, and again Dovecot had these huge memory usage figures. It seemed to read the mailbox at a decent speed - 20 seconds or so. But if I made Dovecot look at another mailbox, and then again at this big target mailbox (say with another client - Netscape 7), it would read the big mailbox at Dovecot's usual high speed - without the high memory usage and I think without high CPU usage as well. Without knowing anything about how Dovecot works, I imagine that there is some kind of caching algorithm for writes, and that this is retained until Dovecot (or at least the instance serving this client) is asked to look at another Maildir. It seems that reading is not slowed by this process much or at all - but writing gets progressively slower as the cache gets bigger. The memory usage - even 49 Megs for RSS - seems excessive. It reached that about halfway through writing the mailbox, so the entire message contents at that state would have been about 22 Megs. But the "SIZE" memory usage is even larger - perhaps limited by the available RAM. This slow speed for writing Maildirs with large numbers of messages is currently a barrier to me using Dovecot. I am about to go back and try again to get Courier IMAP to do what I want . . . The Courier IMAP documentation and what I regard as the difficult "configure -> build -> install -> wonder why it doesn't run" process has cost me so much time that I would be very happy to use something simpler and easier (for me, at least) to install. Thanks for developing this new IMAP server! - Robin

They are not many (10-15). b) The authentication right now is done through PAM, the pam.d/dovecot file is: auth required pam_unix_auth.so account required pam_unix_acct.so password required pam_unix_passwd.so session required pam_unix_session.so I want to authenticate against an SMB server, I added the following /etc/pam_smb.conf: SPECTRON-MSIM MAIN MAIN # documentation says I need 2 servers (only have one, is this ok) and changed the pam.d/dovecot to: auth required pam_smb_auth.so account required pam_smb_auth.so # there is no pam_smb_acct password required pam_smb_auth.so # there is no pam_smb_passwd session required pam_smb_auth.so # there is no pam_smb_session and it doesn't work. I obviously did something wrong, but don't know what, and I found nothing that could help me on google. I have samba installed and it works so It's PAM that I'm configuring incorrectly. Hope someone here can help me. Fawzib Rojas

[Dovecot] Quotas once again
by Mike Machado 14 Jun '03

14 Jun '03

Its been a while since I tried dovecot on my mail server where I have quota issues. I am using mbox file format. There still seems to be a quota problem. I have only /var with quotas and basedir is under /usr (not quotaed). default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u. I tried with mbox_locks = dotlock fcntl (1st set of logs below) and with mbox_locks = fcntl (2nd set of logs) dotlock: Jun 12 17:02:49 newrook pop3(mike): open(/var/mail/mike.lock) failed: Disk quota exceeded Jun 12 17:02:49 newrook pop3(mike): file_lock_dotlock() failed with mbox file /var/mail/mike: Disk quota exceeded Jun 12 17:02:49 newrook pop3(mike): open(/var/mail/mike.lock) failed: Disk quota exceeded Jun 12 17:02:49 newrook pop3(mike): file_lock_dotlock() failed with mbox file /var/mail/mike: Disk quota exceeded Jun 12 17:02:49 newrook pop3: I/O leak: 0x8050930 (0) Jun 12 17:02:49 newrook pop3: I/O leak: 0x807baac (1) fcntl: Jun 12 16:45:32 newrook pop3-login: Login: mike [127.0.0.1] Jun 12 16:45:33 newrook pop3(mike): file_set_size() failed with mbox file /var/mail/mike: Disk quota exceeded Jun 12 16:45:33 newrook pop3(mike): file_set_size() failed with mbox file /var/mail/mike: Disk quota exceeded Jun 12 16:45:33 newrook pop3: I/O leak: 0x8073a2c (1) Jun 12 16:45:33 newrook pop3: I/O leak: 0x804a470 (0) I am using the latest CVS (as of 5 minutes ago). Wasn't this supposed to be working? Have I missed something? My sole goal is to allow people to delete mail when they are out of disk space. -- Mike Machado mike(a)innercite.com InnerCite Inc.

Re: [Dovecot] when/where to set MAIL env variable?

Andrew Basterfield wrote (in a msg I don't think made it to the list): > In dovecot.conf > > default_mail_env = maildir:~/Maildir Ah, silly me... default_mail_env = mbox:~/Mailbox works wonderfully, and is easier than trying to figure out where the MAIL environment variable actually comes into play. Thanks...

[Dovecot] when/where to set MAIL env variable?
by Mike Brown 12 Jun '03

12 Jun '03

I am trying to get dovecot to work on a system that uses qmail as its MTA. As is typical on such systems, the user's primary inbox is an mbox file called Mailbox, in their home directory. Global shell config files /etc/csh.cshrc and /etc/profile set the MAIL environment variable to ~/Mailbox for the users, which is enough to satisfy their interactive mail clients such as pine, mutt, and elm. The mail-storages.txt file in the dovecot docs seems to say that dovecot will not have a problem with this kind of setup. However, I can't figure out how to make it work. The MAIL variable is only set for users who are using shells like tcsh, bash, etc. The server apparently does not operate in a shell, so it is looking in some other location, perhaps /var/mail/$USER, so everyone's INBOX appears to be empty. It would help if mail-storages.txt, when referring to environment variables such as MAIL, would clarify *whose* environment variables are being referred to. Is it the environment of the user who built dovecot? Is it the environment of the user running the main dovecot process? Is it the environment of the user who is checking their mail / the user that dovecot runs setuid as? When and where do I set the MAIL variable so that dovecot will see it? Or is there some other problem? Any help appreciated...
