[Dovecot] New index file code
by Timo Sirainen 31 Jul '03

31 Jul '03

I just had to write this even while it's not just yet in CVS, but it's only a few fixes away from being committed.. My year long dream has finally came true :) [Summary: Next release will have REALLY kickass indexes] Previously the biggest problem with caching message data in indexes was that we had to do it while syncing the mailbox, before client even saw those messages. This caused index rebuilds to be very slow since it had to go through all mails and cache all of them, even if client never would access them. Alternative was to not cache anything at all, but that wasn't really good idea either. Now Dovecot caches the data when client is actually requesting it. That way it will never do any extra work for caching something that client isn't currently interested in. There's still the anticipatory caching for data that client is likely to be interested in later, but that is done only when it doesn't cause extra disk I/O. The reason why it took this long was because it was previously too difficult with read/write locking that indexes required. I couldn't have relied on it working since changing from read lock -> write lock could deadlock and dropping the lock in the middle would have caused even more problems. So, what I did was to rewrite the cache file handling completely: - It doesn't require any locking to read from it. - It will be NFS-safe without being too costly. - The file format itself is now architecture-independent. - Uses less space than before - OpenBSD support is now worse than before, even worse than NFS-support. They should get that unified cache done. Cached data is also selected better: - Specifically requested message headers are cached (FETCH, SEARCH, SORT, THREAD, etc.) - IMAP ENVELOPE isn't treated in any special way anymore. It's treated just as if you had requested HEADER.FIELDS (Date Subject From ...etc.). - Maildir filenames aren't constantly updated in the cache file anymore. This takes more memory now, but should reduce disk I/O. There's a few more tweaks that I'll probably add later: - Maildir: When compressing cache file we update mail's filename to current one so if message's flags aren't changed often, it won't use any extra memory either. - A normal text/plain message doesn't need to have it's IMAP BODYSTRUCTURE cached. It only needs a single bit set in flags. Should reduce used space quite a lot. - Message with only one body part doesn't need to have it's body structure stored at all since it's mostly just useful for fetching body parts. Plus the body structure could be generated if message sizes were known. All this work was only for index cache file (ex. .data file). There's still the main .imap.index file and modify log files. Modify log should be easy to make NFS-safe - I'm currently using some stupid file locking to figure out when the file is safe to overwrite, but I should have simply replaced the old file with rename(). That will solve some other problems as well as make the code simpler. It should be possible to be made read-lockless as well. The main index file is more problematic though. It contains a lot of changing fields in the header, such as number of messages, number of seen messages, etc. I can't think of any way to make it safe to read these fields without locks (my previous ideas didn't actually work). Lockless reads are pretty much a must for scalable NFS-safety. I think it could be done by simply removing all the constantly changing headers. If you want to know how many seen messages there are, just read all the records in the file and count them. Expunging would be done by rewriting the file and rename()ing it over the old file. Appending new messages is a bit tricky to do safely, but I think I know how to do that too.. read/write locks allow the changing headers, but there's locking contention problems with shared mailboxes.. I think I'll make it optional how to do this. Oh, and I also thought how indexes would work with shared mailboxes. You could use one shared cache file, but each user would have their own main index and modify log. That would allow storing per-user flags in the index file and also expunge (hide) messages by removing them from user's index.

[Dovecot] Is dovecot NFS safe?
by Adam Shand 29 Jul '03

29 Jul '03

I'm migrating our mailserver from cyrus 2.0 to Postfix and Dovecot. We're using maildirs delivered to /var/maildir, which is mounted via NFS from a Netapp. My understanding was that maildir was completely happy in an NFS environment but I've seen a couple messages here recently which mention the dovecot index files not being NFS safe. Are their any caveats or gotcha's that I need to be aware of? Thanks, Adam.

[Dovecot] Namespaces
by Timo Sirainen 27 Jul '03

27 Jul '03

0.99.11-test4 release: http://dovecot.procontrol.fi/test/ Finally namespaces somewhat working. Example: namespace private { separator = / prefix = INBOX/ location = maildir:~/Maildir } namespace private { separator = / prefix = #mbox/ location = mbox:~/mail } Problems: - Mailbox listing lists only the first namespace unless you clearly ask mailboxes under some namespace. Not really a problem, but related to: - There should be only one common subscriptions file for all namespaces. This needs some thinking how to do it well. - Having multiple different mailbox formats in one namespace still isn't possible. Needs some more thinking as well.

[Dovecot] API changes and plugins
by Timo Sirainen 26 Jul '03

26 Jul '03

There's been quite a lot of changes in CVS lately, mostly related to API changes but also some index file changes. They've both had very little testing, so there's probably a few bugs left. Especially mbox users should be careful. pop3 might also be deleting wrong messages.. Anyway. The new mail storage API should allow plugins to hook into pretty much any operation they want to. It's not exactly pretty with C syntax, but I think conceptually it's nice object oriented design :) There's example (non-working) quota plugin at: http://dovecot.procontrol.fi/patches/quota.c I also built 0.99.11-test3 from current CVS: http://dovecot.procontrol.fi/test/

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.

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.

RE: [Dovecot] Hooks on folder operations

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.

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?

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?

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..

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.

[Dovecot] New indexing code
by Timo Sirainen 14 Jul '03

14 Jul '03

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] dovecot.procontrol.fi anonymous access fails?
by Marco Molteni 13 Jul '03

13 Jul '03

Hi, just started using dovecot on FreeBSD. Nice and easy to configure :-) I then wanted to browse the dovecot mailing list, so, according to http://dovecot.procontrol.fi/mailinglists.html: IMAP archives available from dovecot.procontrol.fi, either use ANONYMOUS authentication or give anonymous as username and empty password. I was using a patched sylpheed that doesn't support ANONYMOUS authentication, so I gave anonymous as username and empty password, but it failed as shown in the following trace: 1 CAPABILITY * OK dovecot ready. * CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN LISTEXT LIST-SUBSCRIBED AUTH=PLAIN AUTH=ANONYMOUS 1 OK Capability completed. 2 LOGIN anonymous 2 BAD Error in IMAP command received by server. 3 LOGOUT * BYE Logging out 3 OK Logout completed. Anyway, I also tried a plain telnet and it failed in the same way. what's wrong? thanks marco

[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?

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!

[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.

You did a lot of work on nfs-safety for the index files, how about the other files? And does it need specific configure options? Thank you for this release though, I will have a look at it tonight ;-) Kind regards, Maikel Verheijen.

Hi all, I want to migrate our customers mailserver (400 mail accounts), from cyrus-2.0.16 to Dovecot. Anyone an idea how I can preserve the read/unread status and what can I do with the UIDL? (cyrus used a different algorithm for UIDL). Thanks in advance. Best regards, Jens Gutzeit

[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 } }
