Timo, The gdb analysis is attached. It looks like memory got seriously stomped in this core dump. There was no assert or other useful information in the syslog. My setup: Solaris 9, imap and imaps, mbox format, INBOXes NFS mounted, index files on local ufs filesystem, beta8 configured like so: VERSION=1.0.beta8 CC=gcc CFLAGS="-g -O" CPPFLAGS=-I/opt/openssl/include LDFLAGS=-L/opt/openssl/lib \ ./configure --prefix=/opt/dovecot.$VERSION \ --with-ssl=openssl \ --with-ssldir=/opt/openssl/ssl \ --with-sql-drivers=no \ --disable-ipv6 \ > configure.out Jeff Earickson Colby College

[Dovecot] 1.0rc19 with plugins on AIX 5.2
by Ralf Becker 03 Feb '07

03 Feb '07

Hello, has anyone out there successfully build dovecot on AIX with plugins supported? I'm talking about an dlopen error when a plugin tries to access global symbols, that are defined in the dovecot "parent" binary For example: # MAIL_PLUGINS=zlib /usr/local/libexec/dovecot/imap imap(root): Error: dlopen(/usr/local/lib/dovecot/imap/lib20_zlib_plugin.so) failed: rtld: 0712-001 Symbol i_error was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol i_stream_get_data was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol i_stream_skip was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol i_stream_seek was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol i_stream_close was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol i_panic was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol pool_get_exp_grown_size was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found. Additional errors occurred but are not reported. Maybe libtool is the problem, because it does not export global symbols correctly. Or would a newer version of AIX vac fix this? Any ideas? I'm using dovecot 1.0rc19, AIX 5.2-06 and vac 5.0.2 Regards, Ralf -- ______________________________________________________________________ Dipl.-Inform.

[Dovecot] Automatic Folder Expiry (plugin?)
by Troy Engel 02 Feb '07

02 Feb '07

Greetings, I'm migrating an existing Courier IMAP installation to Dovecot (1.0rc19 right now) on a new server; there's one feature I'm not sure if Dovecot supports - but it might and I'm missing it, so I'll ask. In Courier there's an option to expire a folder after a given time period; ostensibly it's to keep a Trash folder clean, but we use it to keep the Junk folder (where spam is delivered by Exim) clean. How can I do this in Dovecot? Here's the chunk from Courier for those unfamiliar with it (just part of the verbiage): ##NAME: IMAP_EMPTYTRASH:0 # # The following setting is optional, and causes messages from the given # folder to be automatically deleted after the given number of days. # IMAP_EMPTYTRASH is a comma-separated list of folder:days. # # Important: the purging is controlled by CTIME, not MTIME ... So in our case it's set like so: IMAP_EMPTYTRASH=Junk:14 Thanks for any help/ideas - I'm not sure if we can live without this feature, the amount of spam is horrendous and users never clean out that folder. -te -- Troy Engel | Systems Engineer Fluid, Inc | http://www.fluid.com

[Dovecot] Planning a dovecot deployment: issues and questions
by Dan Price 02 Feb '07

02 Feb '07

Hi folks, I am currently evaluating Dovecot for deployment to ~200 software engineers (so, heavy email users); I'm hoping this list could provide wisdom about how best to do the configuration, evaluation and deployment, and what testing folks have done to determine whether dovecot is right for their site. Below I've listed the diffs between the dovecot-example.conf and our config. I've been playing with 1.0rc19 running on Solaris Nevada. We have set it up on our server on an alternate port from the existing IMAPd, which is something ancient, horrible and problematic. We're using sendmail and mail.local as our MTA and MDA, respectively, as these ship with the OS, and we need to test them. I have some users who have volunteered to experiment with the server, and they are starting to do so. I've also seen the "flags" problems others have mentioned on the list, and I do not think I could deploy to production with that bug affecting the users. I also have some issues which I'm not sure have been previously reported: One user (of my 4 test users) is occasionally seeing a bug in which mutt 1.4.2.1 claims to be "[downloading xxx/30724]" headers. Upon getting very near to the 30724 total, the total rises to something like: "[downloading xxx/50132]". And on and on. The actual number of messages in the box is 30724. This is not very reproducible, and we do not yet know if it's a problem with mutt or dovecot. Another, using Apple's Mail.App reported: "Everything was working fine until i quit out of my mail app (Mac mail) and restarted. Then i saw weird things: - messages wouldn't get marked unread - messages from eons ago started showing up in my Drafts folder - Inbox would keep spinning/loading - then eventually Inbox just hung showing me no messages" Any thoughts about how to approach these issues? I don't really have a feel for how to go from user-observed-app-doing-X to imapd-is-doing-Y. The big challenge for our site may be mailbox size: the median mailbox size is 62M, the average is 176M and the largest is 1.1GB. I'd be curious to know what sort of mailbox sizes other sites have experienced, and how widespread the use of the Dovecot MDA is-- is this likely to make a big difference for us, and will we have to migrate our (approximately 25) procmail users to sieve? Having read the recent discussions about "1.0", I think my team would really appreciate knowing how to obtain something that was thoroughly vetted and worked highly reliably. If major changes are coming, I think it'd be great to have a 1.0.x stability focused tree, and a 1.1.x (or 2.x.x) feature tree.

[Dovecot] 1.0.rc20 released
by Timo Sirainen 02 Feb '07

02 Feb '07

http://dovecot.org/releases/dovecot-1.0.rc20.tar.gz http://dovecot.org/releases/dovecot-1.0.rc20.tar.gz.sig So, rc19 was somewhat broken. How about this version? + dovecot: Added --log-error command line option to log an error, so the error log is easily found. + Added mail_log_max_lines_per_sec setting. Change it to avoid log throttling with mail_log plugin. - Changing message flags was more or less broken in rc19 - ACL plugin still didn't work without separate control directory - Some mbox handling fixes, including fixing an infinite loop - Some index file handling fixes - maildir quota: Fixed a file descriptor leak - If auth_cache was enabled and userdb returned "user unknown" (typically only deliver can do that), dovecot-auth crashed. - mail_log plugin didn't work with pop3

[Dovecot] namespace subscription problem
by Nate Sanders 02 Feb '07

02 Feb '07

Greetings, I am trying to setup a private namespace in dovecot and running in to some troubles. Here is my setup: > default_mail_env = maildir:~/Maildir > > # default namespace > namespace private { > separator = . > prefix = > inbox = yes > } > namespace private { > separator = . > prefix = maillog. > location = maildir:/var/maildir/maillog/Maildir/ > #inbox = yes > hidden = no > } So far it's working to a degree. When I load my imap folder and go to Subscribe, I can see the master "maillog" folder, and expand it to see all the subfolders. The problem is, I cannot subscribe to the master "maillog" folder. Only it's sub folders. When I check dovecot.info it says this: > dovecot: 2007-01-31 13:27:42 Info: imap(nate): Namespace: > type=private, prefix=maillog., sep=., inbox=no, hidden=no, > subscriptions=no I see there "subscriptions=no". Is it possible to change this to yes? Would changing this to yes allow me to subscribe to the actual namespace folder? I tried adding "subscriptions=yes" and "subscription=yes" to dovecot.conf but both entries resulted in failed starts and errors. How is it possible allow subscriptions directly to this namespace? Thanks. -- Nate Sanders nate(a)ima.umn.edu Associate Systems Manager (612) 624 - 4353 Institute for Mathematics and its Applications

[Dovecot] dspam plugin
by Tom Bombadil 02 Feb '07

02 Feb '07

Hi all... I was looking into the dspam plugin, and it looks very interesting. I saw two version of it around: - one that forks and call dspam - one that calls a store procedure in mysql. I was wondering if we can just log signature and classification into a flat file, instead. The problem is that calling spam can be expensive; And eventhough the myslq solution is brilliant, I dont want to rely on mysql to be alive in order to move the files to/from spam box. Plus, the plugin would be much lighter wihtout libmysqlclient. Any ideas?

[Dovecot] Multiple Trash patch for DSPAM plugin

Hello all, First of all my respects to Johannes for the nice dspam plugin he created. Unfortunatly i got stuck with a problem in that same plugin since it didn't allow the use of more than one Trash folder. That can be an issue if you have a wide variety of clients working in a wide variety of languages. Not all use the english "Trash" for that folder. I've written a small patch to accomodate that situation and it's working just fine for me. I'm submitting it in the hope that it can be usefull to others. Hope it's usefull for others too.

[Dovecot] Performance, dovecot vs tpop3d
by Nate 01 Feb '07

01 Feb '07

Hello, I am new to the list and have spent extensive time researching performance suggestions through the list and the documentation. Particularly interesting is the recent performance thread related to the upcoming release. I just upgraded one of our email servers from tpop3d to dovecot 1.0rc19. tpop3d has served us well for many years; however, it basically has lost all it's support and developers. My main liking of tpop3d was it's speed. After the upgrade to dovecot, the server began to crawl. This server runs postfix for the delivery agent and now dovecot for pop3 and imap. The box serves roughly 9000 virtual maildir mailboxes with roughly 20 pop3 processes active at any given time. I ran some tests this morning to determine an exact difference between running tpop3d and dovecot. dovecot: I/O load averages 81%, System load averages 12.00 tpop3d: I/O load averages 20%, System load averages 0.50 To ensure it wasn't just a fluke of logins, I let each app run for several minutes, and did the test multiple times. The results were not any abnormal user usage and definitely related to application performance. My current settings in dovecot related to performance are: mmap_diable = yes mmap_no_write = yes Modifying these to no seems to decrease performance slightly but only a few percent. I have also played with various other settings, which didn't give me any significant performance boost. I'm eager for the next release which will have the fsync_disable option to see if that helps, it certainly looks promising. One observation where the majority of the load seems to be generated from is when a pop3 connection is loading up a very large maildir. The pop3 process seems to remain around using I/O for a considerable time, even when the user has no new email. Perhaps it is rebuilding or verifying it's index files? Here is an example of a lsof of the pop3 process with a user who has roughly 17000 messages. They check their email every 10 minutes which seems to add significant load. Note the final line, it's reading an individual message file, yet the user has no new email since the last login. If i keep lsofing the process, the final file seems to change and keep going through many of their mailbox files. The process takes many minutes to complete. Is it rebuilding the index on every login?

Thank you for any help offered! I'm hopeful for any suggestions to solve this performance issue or diagnose it further to determine the cause. - Nate

[Dovecot] Making POP3 not retrieve deleted messages

Since my users often use the webmail system to delete messages to save their poor strained dial-up POP3-using mail clients, and our new web mail system isn't expunge-happy like the last one, I found need for this patch -- it adds a configuration option for pop3 "pop3_ignore_deleted", a boolean, that does just that. I'd love feedback. Aria

[Dovecot] Mail Answered status flag in pine stopped working in rc19
by Carl Mason --- Director Demography Lab 01 Feb '07

01 Feb '07

The Flag indicating that a message has been Answered does not work in pine. The status flags for New and Deleted work as always. The Answered flag worked properly in dovecot 0.99, but after upgrading to 1.0rc19 it stopped working. Interestingly, mail that was answered before upgrading to rc19 still shows the proper flag. I have tried with mbox_dirty_syncs turned on and off and I have tried putting "flags" in mail_cache_fields. Obviously I am wandering in the dark. Here is the setup: pine 4.64 dovecot 1.0rc19 (installed from rpm dovecot-1.0-2_40.rc19.el4.at.i386.rpm) Centos 4.4.2 x86 mail_location = mbox:~/mail/:INBOX=%h/.mailspool/%u:INDEX=/var/dovecot_indexes\/%d/%n Inbox is NFS mounted, INDEX is on local disk Thanks.

That test was on my list to try out today. I ran the test, and performance was severely degraded. Upon every new login, the entire index was rebuilt. So with any login it takes the full ~30 seconds to rebuild the index on a 17000 email user. I've confirmed also that tpop3d is doing no indexing whatsoever on disk. It isn't even compiled with that option. So it seems it is probably disk caching which is assisting tpop3d with returning a 2nd login (within a few minutes) so quickly. I wish it were the case that all users downloaded messages, but it seems all too often users click the 'leave messages on server', and never expire them. We have quite a few users (thousands probably) in that condition. We occasionally delete old stuff. Did I hear about an expire plugin upcoming? That would be useful. - Nate

Message Uniqueness in a Mailbox | | | Implementations SHOULD NOT deliver a message to the same folder more | than once, even if a script explicitly asks for a message to be | written to a mailbox twice. | | The test for equality of two messages is implementation-defined. | | If a script asks for a message to be written to a mailbox twice, it | MUST NOT be treated as an error. `---- Dovecot seems to ignore this "SHOULD NOT" or am I missing something ? At first, I thought they were speaking of case where there is two idententic "fileinto" directive in the ruleset. Something like : fileinto "box"; fileinto "box"; But, I don't think that they would they "the test for equality of two messages" with such a trivial case. Maybe dovecot should maintain a list of recent message-id seen for each user (with the associated mailbox). -- I WILL ONLY DO THIS ONCE A YEAR I WILL ONLY DO THIS ONCE A YEAR I WILL ONLY DO THIS ONCE A YEAR -+- Bart Simpson on chalkboard in episode 3F31

[Dovecot] Need help with "mbox sync" problem
by Jim Garrison 31 Jan '07

31 Jan '07

The following is occurring consistently on users in only one vhost domain. Other vhost domains are not having the problem. The email client in use is the same (in both the working and non-working domains). dovecot: Jan 29 21:19:18 Error: POP3(user1(a)mydomain.tld): mbox sync: UID inserted in the middle of mailbox /var/mail/vhosts/mydomain.tld/user1 (5629 > 5423, seq=2, idx_msgs=5) dovecot: Jan 29 21:19:18 Info: POP3(user1(a)mydomain.tld): Disconnected: Logged out top=0/0, retr=95/508506, del=95/95, size=506866 dovecot: Jan 29 21:19:52 Error: POP3(user2(a)mydomain.tld): mbox sync: UID inserted in the middle of mailbox /var/mail /vhosts/mydomain.tld/user2 (5634 > 5629, seq=2, idx_msgs=95) dovecot: Jan 29 21:19:52 Info: POP3(user2(a)mydomain.tld): Disconnected: Logged out top=0/0, retr=5/69654, del=5/5, si ze=69562 Once this message starts occurring, dovecot stops deleting retrieved messages when the user retrieves mail (with 'delete from server' set). The result is that the entire mailbox contents are fetched each time, resulting in copious amounts of duplicate messages. I'm on the rc8 RPM that comes with FC5, but am willing to remove it and install a later Dovecot built from source. 1) Is this a known problem that can be fixed by upgrading? 2) If not, can someone tell me what this message means exactly, and how to gather more information for debugging? The MTA is Postfix. Thanks

[Dovecot] How to prevent SQL injection
by Jochen Schulz 31 Jan '07

31 Jan '07

Hi, on my way home today I thought a little bit about my setup which involves user and password lookups in an SQL database (Postgres). I asked myself whether I need to do anything to prevent SQL injection via forged user or domainnames. In the wiki I didn't find anything specific, only http://wiki.dovecot.org/Variables which mentions that there is the %E modifier which escapes single quites and backslashes. This appears to be a good idea but I am asking myself whether I need to do this since it is not mentioned anywhere. Is anybody able to comment on this? And BTW, it appears that one can use several modifiers at once. This is only implicitly mentioned in the wiki (You can apply modifier*s*), but it appears to work.

[Dovecot] Looking for IMAP maintenance tools
by Jens Knoell 31 Jan '07

31 Jan '07

Hi I'm currently prowling for some IMAP tools to help me maintain our mailboxes. I'd prefer "pure" IMAP, i.e. no messing with file system directly, but would settle for more crude ways if need be. Specifically I am looking for: - Expunge tool: Outlook does not seem to auto-expunge messages in any way shape or form. So I'd like to run a daily cron to expunge all mailboxes. - Quota helper: Some way to send a warning email once a day or so, saying "you're close to your quota limit, please delete some mail" or somesuch Granted, I could write these two from scratch - but why reinvent the wheel? Thanks Jen

[Dovecot] Dovecot 1.0 on a Mandriva 2007 box

I installed the RPM, and fought with it for days before realizing the packaged config file is incorrect. So I downloaded the latest tarball and used the sample dovecot.conf file. I was finally able to get dovecot to run as long as I leave the mail_location line commented out. If I uncomment the line dovecot complains that "mail_location" is an "unknown setting". What am I missing? Thanks, JB

[Dovecot] help a journalist: What do you wish the CIO understood about fighting spam?
by Esther Schindler 30 Jan '07

30 Jan '07

Hi, folks. I'm senior online editor at CIO.com, and I'm working on an article for which I'd very much like your help. There's often a lack of communication between techies and top company management. Maybe they don't want to hear about problems; perhaps you give them technical details that are far more granular than they want to know. But dealing with spam is a topic that every e-mail admin has to cope with -- and I'm not sure that the CIO knows the real issues. I have the ear of the boss, however. Essentially, I'm trying to put together the collected wisdom of e-mail and network admins in a fashion that CIOs will understand. Or at least one teeny corner of it. So I have a very simple question to pose to you: ***If you could get your CIO (or top management) to understand one thing, just ONE thing, about fighting spam, what would it be?*** And the follow-up: why did you pick that one item? Feel free to share anecdotes, horror stories, even success stories. While I hope that every CIO will read this article, I also hope that it becomes the document you bring to a new manager ("Here: this is what's important to me"). I'm sure there are plenty of other things that you wish your CIO grokked, whether about e-mail administration or other topics (not the least of which is "the e-mail admin is underpaid"). But I do have to limit myself somehow, and "what's important about fighting spam" has a lot of leeway. I'll be sure to stop by here (as I expect others want to participate in the conversation), but feel free to cc me with your response or send me a private message. I'm hoping for a rather fast turnaround on this article, so please blurt out your first thoughts rather than plan on writing a nice, leisurely response. If all goes well, I'd like to get this article posted in the next couple of weeks. Please be sure to let me know how to refer to you in the article; the usual format is &name, &title, &company and &location ("Esther Schindler is a senior developer at the Groovy Corporation in Scottsdale Arizona"). If you give me some kind of context I'm willing to work without one. That is, I do need some identifying characteristics to give the article credibility ("Esther works at a large finance company in the Southwest").

[Dovecot] Cannot fill the maildir with mails
by Peter Selter 30 Jan '07

30 Jan '07

Hello! I have installed Dovecot yesterday as a simple connection between a local mailbox and Novell Evolution. I have set up a POP3 service that I can succesfully connect to. I chose the Maildir structure but the whole box is empty. When I try "echo ´test´ | mail -s ´test´ user42" it doesn´t reach the mailbox. What can I do? I could also try the mbox format but Evolution has problems connection to an mbox file, it just says "loading..." and nothing happens. Any help would be appreciated :-) regards, Peter ____________ Virus checked by G DATA AntiVirusKit

[Dovecot] popa3d migration
by FiL ＠ Kpoxa 30 Jan '07

30 Jan '07

Hello, I'm sure there is no good answer to my question, but it doesn't take much to ask, so I will. I am about to migrate my current Dovecot IMAP + Popa3d mailbox server to Maildir. I need to keep both protocols (IMAP and POP3) and will be switching to Dovecot on both. The question is simple - is there any way to keep POP3 UIDs through migration, so people won't get duplicates in their inboxes. Second question is not that important but if somebody has a good answer it will be really nice - is there any way to keep IMAP UIDs? With IMAP it won't create dups, but loosing (changing) UIDs will create extra load on the server. I know, this is more about mailbox->Maildir conversion, not dovecot, but this is the only place I can ask this question P.S. am running dovecot on linux FC5 right now, but will be upgrading to FC6 / dovecot 1.0 release at the time of migration. Won't do it before 1.0 final comes out Thank you, FiL

[Dovecot] dirsize quotas crashing 1.0.rc19
by Dean Brooks 29 Jan '07

29 Jan '07

Hi, I've been trying to get dirsize quotas to work properly with 1.0rc19 and Dovecot consistently crashes when attempting to do file copies once a user is over quota. Dovecot works fine for us for regular mbox based IMAP, but as soon as I add the following two entries in their respective locations in dovecot.conf: mail_plugins = quota imap_quota (in the imap{} section) quota = dirsize:storage=2000 (in the plugin{} section) If a user goes over quota, and they attempt to copy a file to a folder via IMAP, all I get is this: dovecot: [ID 684838 mail.error] child 20868 (imap) killed with signal 10 Is anyone successfully using dirsize:storage quotas with 1.0rc19? If so, can someone else verify if they see crashes like this? As soon as I remove the quota plugin, the crashes go away and all is good, so there's obviously some sort of problem in the quota plugin.

Re: [Dovecot] repeat downloads of message headers in 1.0rc19
by James Garrison 29 Jan '07

29 Jan '07

I reported this against rc7 and rc8, and still see it occasionally. (I'm running the rc8 that comes with Fedora 5). It is always associated with this message in dovecot.log: dovecot: Oct 23 19:26:17 Error: POP3(user(a)domain.tld): mbox sync: UID inserted in the middle of mailbox /var/mail/vhosts/domain.tld/user (12 > 4, seq=2, idx_msgs=5) Once this happens, dovecot will refuse to clear out the mbox file when the user retrieves email via POP. Each time the user logs in to retrieve mail s/he gets everything in the mbox, which continues to grow. The only fix I've been able to find is to manually delete the mbox file.

[Dovecot] repeat downloads of message headers in 1.0rc19
by Brian G. Peterson 29 Jan '07

29 Jan '07

I upgraded one server to 1.0rc19 (from rc15) over the weekend, and have since received several reports of dovecot erroneously retrieving older messages as new mail. I've seen this myself intermittently on KMail, and users have reported it on Thunderbird, Squirrelmail, and Outlook. I see some things in the archives that suggest that this was a problem in older 1.0 release candidates, but hadn't experienced the problem myself until just now. Has anyone else seen this problem?

[Dovecot] Best small server config
by - 29 Jan '07

29 Jan '07

Hi, Busy with dovecot on a linux server with not very much RAM in it (512 MB max total). On this server dovecot will only handle about 12 users, with never more than 3 IMAP webmail users at a time, and a maximum of 2 POP3 users at a time using it. I'm going all secure later on, but first I would like your opinion on what configuration best to use with, say, max 5 users busy at one time, and have it use as little RAM and CPU as possible. (Same machine is also running httpd, squirrelmail, php5, postfix, clamd, clamsmtpd, sshd.) Here's my /etc/dovecot.conf now: # protocols = imap pop3 imap_listen = * pop3_listen = my.servers.ip.address (hidden for this list) ssl_cert_file = /etc/ssl/certs/imapd.pem ssl_key_file = /etc/ssl/private/imapd.pem ssl_parameters_file = /var/run/dovecot/ssl-parameters.dat ssl_parameters_regenerate = 320 login_dir = /var/run/dovecot-login login = imap login = pop3 default_mail_env = maildir:/home/%u/Maildir mailbox_idle_check_interval = 40 mail_full_filesystem_access = yes login_user = dovecot login_process_size = 64 login_process_per_connection = no login_processes_count = 4 login_max_processes_count = 4 login_max_logging_users = 5 max_mail_processes = 140 imap_process_size = 192 pop3_process_size = 64 first_valid_uid = 500 last_valid_uid = 520 mail_cache_fields = MessagePart mbox_locks = fcntl mbox_read_dotlock = no mbox_lock_timeout = 380 auth = default auth_mechanisms = plain auth_userdb = passwd auth_passdb = pam auth_process_size = 64 auth_user = root # Any insight or advice welcomed!

[Dovecot] Benchmarking
by Timo Sirainen 29 Jan '07

29 Jan '07

I wasted too much time today doing this, but they do show a few interesting things: 1) mmap_disable=yes is faster than mmap_disable=no. I didn't expect this. I'm not yet sure why this is, but possibly because then it updates the mail index by reading the changes from dovecot.index.log, instead of reopening and re-mmaping dovecot.index. At least that's the biggest difference between them. 2) Dovecot is faster than Cyrus, at least in test. I didn't really expect this either, because with maildir Dovecot has to do extra rename() calls for all flag changes. I'm guessing it's expunges that are slowing Cyrus down the most (that causes it to rewrite its cache file). 3) fsync_disable=yes + mmap_disable=yes almost doubles the performance with 1 client, and over quadruples the performance with 10 clients. Why fsync_disable=yes + mmap_disable=no doesn't give that big of a performance difference? I've no idea. This is anyway such a large performance increment that I'll probably go and backport this setting to v1.0 too :) 4) Dovecot's mbox code kicks maildir's ass. 5) dbox is surprisingly slow. I'll have to find out why. I don't think it should be that slow. 6) Courier.. Well, it probably doesn't come as a shock that Dovecot is almost twice as fast. Note that Courier doesn't call fsync(), so it can't be compared to Dovecot's fsync_disable=no numbers or to Cyrus. Oh, one other difference between Courier and others was that it didn't support LITERAL+ extension, so it maybe could have done a bit less appends than others. 7) CVS HEAD and branch_1_0 don't seem to have that big of a performance difference. All the tests were done using my IMAP tester: http://dovecot.org/tools/imaptest.c The mailbox data that was being appended was Dovecot's mailing list: http://dovecot.org/archives/dovecot.mbox The linefeeds were converted to CR+LF. However, for the Dovecot CVS HEAD runs the mails contained also those extra X-UID, Status, etc. headers which I had to remove before Cyrus would accept them (the lines didn't contain CRs).

[Dovecot] dovecot patch for filesystem quota

The attached patch fixes it for me, and I suspect is also correct for others BSDs.

[Dovecot] POP3 logging in wrong timezone
by - 27 Jan '07

27 Jan '07

I have dovecot running on a CentOS 4.4 server, and it is logging IMAP entries just fine, in the right timezone (GMT+1), which the server itself is running on (CET), but pop3 is being logged in GMT 0, so 1 hour too early. pop3 log-entries are at the right position in the maillog, but with the wrong time next to it. Now I've read some messages in this list about this bug (or feature), but have no clue as to how to solve it. Anyone? Thanks in advance, Ben

[Dovecot] per-network auth mechanisms
by George Moury 27 Jan '07

27 Jan '07

Hi All, I need use different auth mechanisms for different IP-address of IMAP/SMTP SASL clients (allow plain authorisation only for my own network), but there is no examples at wiki.dovecot.org for this feature. Is this feature available at rc19 version? Thank you in advance. Best regards, George

[Dovecot] Advice, Converting a Live/Production server.
by Michael Dilworth 26 Jan '07

26 Jan '07

I want to mess with a live server. (a Bad thing). I have googled until my eyes boogled, wiki'ed until my fingers are wonked, have read as much as I can read, however I'm left with a few questions/worries. Issue: I am currently running Dovecot as a pop3 server with standard /var/mail mbox's I would like to run a mixed Imap/Pop3 server with ~/maildir inbox's The thread http://www.dovecot.org/list/dovecot/2006-February/011304.html is fairly close to what I want to do, but I would like to go ahead and convert to maildir. (Mixed pop3/imap access for each user) I don't have a system to test, "I used have one but it's now the production server... PW/Disk failed, thank G-D(s) for rsync/backups". Setup: procmail, dovecot 1.0 beta 8.2 (fc5), squirrelmail. all users use outlook (2000,2003) or outlook express (random versions) (^^^^ not my choice, I just have to deal with it {and use it} ^^^^^) the majority of users will continue to use pop3, however some would like to convert to imap and have all mail stored on the server. Questions: /etc/procmailrc? just set default to ~/maildir? do I need to define "INBOX"? aka $MAILDIR=~/maildir/, $ORGMAIL=~/maildir/, $DEFAULT=~/maildir/ Same as above, what about new/cur should I set up a /etc/skel? close to above, if I create rules, for spam, etc. do I need to worry about cur/new. close to above, what about Sent Items, Drafts etc... for imap users, I do understand that client rules would likely be needed to store sent items. conversion, anything to look for? mb2md seems to work, but some users have "don't delete from server set", will they get dups? (I can live with this) archiving, can I (or a script) mess with the files in the maildir? aka keep the number of files/messages less than 16k for the outlook users. Bugs, should I cool my heals, and wait for rc16 or 1.0 final? I am currently running problem free, and I do hate to mess with something which is not busted. TIA Michael.
