[Dovecot] folder subscriptions
by seth vidal 25 Jun '03

25 Jun '03

Hi, I've got a lot of users using uw-imapd(yah, yah, I know) I'd like to get them off of that and onto dovecot at some point in the indeterminate future. so excluding bizarre path resolution things that uw-imapd has left around. is it more or less cp ~/mailboxlist ~/mail/subscriptions? It looks like that - but I wanted to verify :) thanks -sv

[Dovecot] New dovecot Debian packages.
by Jaldhar H. Vyas 24 Jun '03

24 Jun '03

I forgot to mention it here: Christof alerted me to the fact that there was a typo in my package which was causing LDAP support to fail. So I made new packages bringing them upto 0.99.10.rc2 in the process and uploaded them to unstable last night. They should arrive in the archive today.

[Dovecot] RFC: PAM service name change?
by Jeremy Katz 23 Jun '03

It would be nice for the sake of not conflicting to have the PAM service name not be imap. Especially as the same service name is used for pop as well :) My recommendation would be to use dovecot instead. Any other opinions? Jeremy

[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.

Yes mistakes happen. Why could'nt you (we?) do like proftpd that has a parameter that give the order of authenticators first one wins.

[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.

by Timo Sirainen 18 Jun '03

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?

I can't expect every user to log in and first make this mail directory before they can use their mail account. Dovecot also refuses to show any folders at all, such as the INBOX, when it can't find it's mail(folders) directory. Is this intentional?

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

[Dovecot] Dovecot configuration with passwd-file

I have tried to configure dovecot to use passwd-file authentication and I havent been able to. I changed the following in the dovecot.conf file (I want to have all the mailboxes in one directory): default_mail_env = maildir:/opt/mail/%u auth_userdb = passwd-file /etc/passwd.imap auth_passdb = passwd-file /etc/passwd.imap auth_verbose = yes It gives me the following error (I hoped it would be more verbose than this): Internal login failure: f_rojas [192.168.10.4]. passwd.imap exists, the user and password are ok What am I missing?

[Dovecot] Debian and dovecot
by Spectron International, Inc. 14 Jun '03

14 Jun '03

I have Debian 3.0 (woody) and installed the dovecot packages and it works ok with the default configuration. I want to change the default configuration, is any of this possible? a) I don't want to create accounts for each user, can I have a mailboxes directory with the mailboxes of all the users? 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] 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...

[Dovecot] the most serius problems [part 1]

30 May '03

hi, I try to collect out most serious problem with dovecot. so I write a series of mails:-) the first on is the load. has anybody else use dovecot in a real enviromnt with at least hundreds of users and at least 50 concurrent user at the same time? it seems to me no one else just me. the weekend I move the whole mail system to a quad P4 with 1Gb ram and this server do nothing just imap. yesterday evening I have to delete all .imap.index and other dovecot specific files. and as I wrote today morning the load was about 20-30 !!!. but even in an average day the load is over 2-3 white the cpu load is 1-2% in each of the 4 processor. the system is totaly unusable. what more today I've got other errors. of course all the time when I can't find the colution I try to escape to the latest cvs. today finally I compile a new courier install it to another port and those clients which can't connect to dovecot reconfigure to courier. but they are not compatible!!! I have to set root directory to INBOX in courier while not for dovecot and this is a real big problem. is there any way to compile dovecot to use INBOX as a root directory? since in this case at least there is a chance to switch to courier without reconfigure 300 OE6. I try to help to find out the reason for the load in any way, but it seems to me than it's better to change to courier or cyrus since our users getting angry not to mention my boss. -- Levente "Si vis pacem para bellum!"

[Dovecot] 0.99.10-test8

http://dovecot.procontrol.fi/test/ Again major maildir syncing updates: - uidlist file is accessed and rewritten a lot less often now than before - mail duplicates are detected and handled properly by renaming them to new base name - message flag updates and expunging before did two full syncs for cur/ directory. now it does only one. - some fixes to syncing in read-only / out-of-quota conditions - before we did always a full sync in cur/ directory when mailbox was opened. now it's done only when needed. - fixed some crash/index corruption cases I think syncing should be now very close to having perfect possible performance.

[Dovecot] Dovecot 0.99.9.1 and openssl-0.9.7a-5
by Robin Whittle 28 May '03

28 May '03

Hi Timo and others, Thanks for Dovecot! I just got it running under Red Hat 9.0 after spending many hours unsuccessfully trying to get Courier IMAP to run, although I have done it in the past. Here is a compilation glitch which may already be well known: I compiled dovecot-0.99.9.1 on my newly installed and recently updated (via Red Hat Network) system and the compilation stopped due to a missing file in the SSL headers: In file included from /usr/include/openssl/ssl.h:179, from ssl-proxy-openssl.c:14: /usr/include/openssl/kssl.h:72:18: krb5.h: No such file or directory In file included from /usr/include/openssl/ssl.h:179, from ssl-proxy-openssl.c:14: The currently installed OpenSSL RPM was openssl-0.9.7a-5. This lacks the file /usr/include/openssl/krb5.h . I understand that openssl-0.9.7b is OK, but I wasn't sure about whether installing this as a tarball from http://www.openssl.org would upset any other programs on this machine, or confuse the RHN update system. I didn't really need SSL and I couldn't see a specific option for disabling it, other than a general instruction about disabling modules with a ./configure option. So I tried ./configure --help and compiled it with: ./configure --without-ssl This worked fine. I really like the report at the end of the ./configure stage saying how the program will be compiled! - Robin // Robin Whittle http://www.firstpr.com.au // Melbourne, Australia http://fondlyandfirmly.com

[Dovecot] Dovecot in OpenBSD ports system

27 May '03

Hi I have put together dovecot port for the OpenBSD ports system. The port has yet to be submitted, but is finished awaiting testing from a wider audience. I have been using dovecot successfully on OpenBSD/sparc64 -current for months now with no problems. Would you recommend including the CR+LF patch? http://cemetery.homeunix.org/OpenBSD/dovecot.tar.gz -- http://cemetery.homeunix.org

[Dovecot] still problem with load
by Farkas Levente 27 May '03

27 May '03

hi, we've got (and getting more) serious problem with load. I'm just calculate that ther is about 300 mailbox with 20Gb mails. and the whole system is _very_ slow and just getting slower and slower. it's a fast lan every client has 100Mb connection to the server with gigabit crad and gigabit switches. when I push the delete button in a mail I usualy have to wait 10,20 or 30 seconds (!!!) to deleted and show me the next one. dovecot eat so much io to the hard disk, that we can't do too much. currently at the same time about 100 clients are connected mostly with OE6. the server is a P4 server with 1GB ram and about 1TB hard disk. there is only one samba and dovecot on the server. and the load use to be something like this: ---------------------------------------- 10:47:38 up 3 days, 15:48, 2 users, load average: 4.64, 3.58, 3.43 230 processes: 225 sleeping, 5 running, 0 zombie, 0 stopped CPU states: 6.3% user 8.9% system 0.0% nice 0.0% iowait 84.6% idle Mem: 1022840k av, 1013588k used, 9252k free, 0k shrd, 80320k buff 826372k actv, 47324k in_d, 16904k in_c Swap: 4193608k av, 80612k used, 4112996k free 783088k cached ---------------------------------------- as you can see it use almost all ram (as the 2.4 kernmel used to do) but no cache. so the ram is enough. the more interesting part is the load while the idle usualy between 80-90% the whole system doesn't use any cpu (or just minimal). BUT at the same time the load is around 3,4,5 (!!!) which is too much, and more than acceptable. what's worse the reason is the io load on the hard disks. every process are waiting for io. in this case I usualy service dovecot stop killall imap <wait about one minutes> service dovecot start and the load goes back to 0.3-0.6. after an hour the same happend and I have to do the same.:-((( what's more in this case samba case that all (!!!) clients stops for a few seconds. since everybody use OE6 they always download all messages with huge mailboxes what's more dovecot index the whole system all the time. I assume this cause the load. IMHO 300 mailbox and 100 concurrent user is not such a big thing. is there any way to restrict dovecot not to use so much io? thanks in advance. -- Levente "Si vis pacem para bellum!"

[Dovecot] pop3 timeout when sending first message
by Mike Brown 27 May '03

27 May '03

I'm using FreeBSD 4.8 with dovecot from the ports collection. First I am first trying to fetch mail via POP3. Clients are both OE6 and Mozilla. Both exhibit the same behavior: the client says it is receiving message 1 of (however many), but nothing happens; no message data is transferred. Mozilla seems to keep waiting forever, but OE6 times out after 60 seconds and lets me stop waiting. I tried both with and without SSL. Authentication works fine in either case, but the mail xfer just doesn't work. There's nothing of interest in the logs. By the way, there seems to be no mention of what syslog facility is used by dovecot. What is it? I'm avoiding syslog for now and writing to specific files. In the info log I get this when the client logs in: pop3-login: May 25 23:10:44 Info: Login: mike [my.IP.addr.here] In the other log I get this when OE6 disconnects, following the timeout and prompting me to wait or stop: pop3-login: May 25 23:11:53 Warning: SSL_read() syscall failed: EOF [216.241.45.45] I'm not sure what else to do to try to debug this... Help? -Mike

[Dovecot] Why dovecot is not multi-threaded?
by Ruben Alvarez 26 May '03

26 May '03

Hi, I'm looking for the most efficient OpenSource IMAP server and I am told that Dovecot Server is a good solution. Anyway, I have inspected the source code and I think Dovecot is not a multi-threaded server, but a forked server. I am surprised about this issue, because threads perfomance should be higher than creating a new process for each connection....I suppose. So, Could anybody tell me why Dovecot was not designed with multi-threaded support?. Perhaps, threads are not a good solution for Dovecot but I am very interested in which are the reasons for this. By the other hand, ¿do anybody know any multi-threaded OpenSource IMAP server?. I would like test performance of Dovecot server versus a multi-threaded one. Very thanks.

[Dovecot] logging in POP3
by Jens Laas 26 May '03

26 May '03

I have begun testing dovecot as (primarly) a POP replacement. So far the only lacking bit is the logging. It would be great if pop3 could log a line at client exit with the following info: (wishlist follows :) o nr deleted mails + total bytes deletes o nr mails left in spool + bytes left o time spent o indication if TLS was used or not If you would lika generic logging API I have one you can use: (Only tested under Linux. It is GPL) http://robur.slu.se/jensl/jellog.tar.gz Excerpt from headerfile: /* Functions for setting the destination of logger_facilities. - filename is the file to append log entries to. If file does not exist it is created with umask 0666 (modified as usual by open() call). - filestream is the FILE stream to use. - fd is the filedescriptor to use. - priority is the syslog priority to use as used in the syslog() call. - timestamp is used as a boolean. True means begin line with a timestamp. */ int logger_set_file(logger_facility facility, char *filename, int timestamp); int logger_set_iostream(logger_facility facility, FILE *filestream, int timestamp); int logger_set_fd(logger_facility facility, int fd, int timestamp); int logger_set_syslog(logger_facility facility, int priority, int timestamp); /* fmt = [sdt]+ s = string d = integer t = time-string Example: logger( LOGGER_ERROR, "sds", "Errorcode: ", -1234, ".

[Dovecot] 0.99.10-test1
by Timo Sirainen 19 May '03

19 May '03

http://dovecot.procontrol.fi/test/ Maildir syncing now works pretty much as described in my earlier mail. It was quite a large change, so please test this :) So the new and great features: - It's faster. - If someone renames maildir file just before we try to use it, we now resync the maildir and try to find it again. Before we just failed. It's also possible that the filename changed again while we resynced, so we try max. 10 times before failing (yes, we know if we should try resyncing so we don't always scan it 10 times). - Read-only maildirs work now. If we don't have write access to dovecot-uidlist, we'll show only those mails which are already there. - Out of quota/disk space failures are handled well now. All except updating dovecot-uidlist file which is a bit tricky. - :CONTROL=dir in default_mail_env can specify where to save dovecot-uidlist and .customflags files. Useful for above problems. I think maildir support is getting near perfect now. Only thing left is to deal with failure to write dovecot-uidlist when out of quota. Oh, and NFS safe .customflags file.

[Dovecot] Maildir synchronization
by Timo Sirainen 17 May '03

17 May '03

I thought I'd send this here too, since I spent so much time writing it as comment to maildir-sync.c :) Now only thing left to do is to write the code to match it. /* Here's a description of how we handle Maildir synchronization and it's problems: We want to be as efficient as we can. The most efficient way to check if changes have occured is to stat() the new/ and cur/ directories and uidlist file - if their mtimes hasn't changed, there's no changes and we don't need to do anything. Problem 1: Multiple changes can happen within a single second - nothing guarantees that once we synced it, someone else didn't just then make a modification. Such modifications wouldn't get noticed until a new modification occured later. Problem 2: Syncing cur/ directory is much more costly than syncing new/. Moving mails from new/ to cur/ will always change mtime of cur/ causing us to sync it as well. Problem 3: We may not be able to move mail from new/ to cur/ because we're out of quota, or simply because we're accessing a read-only mailbox. MAILDIR_SYNC_SECS ----------------- Several checks below use MAILDIR_SYNC_SECS, which should be maximum clock drift between all computers accessing the maildir (eg. via NFS), rounded up to next second. Our default is 1 second, since everyone should be using NTP. Note that setting it to 0 works only if there's only one computer accessing the maildir. It's practically impossible to make two clocks _exactly_ synchronized. cur directory ------------- We have maildir_cur_dirty variable which is set to cur/ directory's mtime when it's >= time() - MAILDIR_SYNC_SECS and we _think_ we have synchronized the directory. When maildir_cur_dirty is non-zero, we don't synchronize the cur/ directory until a) cur/'s mtime changes b) opening a mail fails with ENOENT c) time() > maildir_cur_dirty + MAILDIR_SYNC_SECS This allows us to modify the maildir multiple times without having to sync it at every change. The sync will eventually be done to make sure we didn't miss any external changes. The maildir_cur_dirty is set when: - we change message flags - we expunge messages - we move mail from new/ to cur/ - we sync cur/ directory and it's mtime is >= time() - MAILDIR_SYNC_SECS It's unset when we do the final syncing, ie. when mtime is older than time() - MAILDIR_SYNC_SECS. new directory ------------- If new/'s mtime is >= time() - MAILDIR_SYNC_SECS, always synchronize it. maildir_cur_dirty-like feature might save us a few syncs, but that might break a client which saves a mail in one connection and tries to fetch it in another one. new/ directory is almost always empty, so syncing it should be very fast anyway. Normally we move all mails from new/ to cur/ whenever we sync it. If it's not possible for some reason, we set maildir_have_new flag on which instructs synchronization to check files in new/ directory as well. maildir_keep_new flag is also set which instructs syncing to not even try to move mails to cur/ anymore. If client tries to change a flag for message in new/, we try to rename() it into cur/. If it's successful, we clear the maildir_keep_new flag so at next sync we'll try to move all of them to cur/. When all of them have been moved, maildir_have_new flag is cleared as well. Expunges will also clear maildir_keep_new flag. If rename() still fails because of ENOSPC or EDQUOT, we still save the flag changes in index with dirty-flag on. When moving the mail to cur/ directory, or when we notice it's already moved there, we apply the flag changes to the filename, rename it and remove the dirty flag. If there's dirty flags, this should be tried every time after expunge or when closing the mailbox. broken clients -------------- Originally the middle identifier in Maildir filename was specified only as <process id>_<delivery counter>. That however created a problem with randomized PIDs which made it possible that the same PID was reused within one second. So if within one second a mail was delivered, MUA moved it to cur/ and another mail was delivered by a new process using same PID as the first one, we likely ended up overwriting the first mail when the second mail was moved over it. Nowadays everyone should be giving a bit more specific identifier, for example include microseconds in it which Dovecot does. There's a simple way to prevent this from happening in some cases: Don't move the mail from new/ to cur/ if it's mtime is >= time() - MAILDIR_SYNC_SECS. The second delivery's link() call then fails because the file is already in new/, and it will then use a different filename. There's a few problems with this however: - it requires extra stat() call which is unneeded extra I/O - another MUA might still move the mail to cur/ - if first file's flags are modified by either Dovecot or another MUA, it's moved to cur/ (you _could_ just do the dirty-flagging but that'd be ugly) Because this is useful only for very few people and it requires extra I/O, I decided not to implement this. It should be however quite easy to do since we need to be able to deal with files in new/ in any case. It's also possible to never accidentally overwrite a mail by using link() + unlink() rather than rename(). This however isn't very good idea as it introduces potential race conditions when multiple clients are accessing the mailbox: Trying to move the same mail from new/ to cur/ at the same time: a) Client 1 uses slightly different filename than client 2, for example one sets read-flag on but the other doesn't. You have the same mail duplicated now. b) Client 3 sees the mail between Client 1's and 2's link() calls and changes it's flag. You have the same mail duplicated now. And it gets worse when they're unlink()ing in cur/ directory: c) Client 1 changes mails's flag and client 2 changes it back between 1's link() and unlink(). The mail is now expunged. d) If you try to deal with the duplicates by unlink()ing another one of them, you might end up unlinking both of them. So, what should we do then if we notice a duplicate? First of all, it might not be a duplicate at all, readdir() might have just returned it twice because it was just renamed. What we should do is create a completely new base name for it and rename() it to that. If the call fails with ENOENT, it only means that it wasn't a duplicate after all. */

[Dovecot] Postfix locking equivalence?
by Warren Togami 17 May '03

17 May '03

/etc/postfix/main.cf.default: mailbox_delivery_lock = flock, dotlock Is flock equivalent to dovecot's fnctl locking? For mbox what type of locking settings should I be using? (No NFS, only local filesystem.) I'm using procmail to deliver mail to my mboxes. Does the above postfix setting effect procmail's locking method? I use rules like this: :0 * ^X-BeenThere: dovecot(a)procontrol.fi DOVECOT If I understand this correctly, :0: in procmailrc would explicitly use dotlocks instead of "kernel-locks" as procmail calls it. I'm not fully understanding all this locking stuff. Warren Togami warren(a)togami.com p.s. Timo, I received your test message after my prior posting attempt bounced.

[Dovecot] help: The current command did not succeed. The mail server responded: Invalid mask.
by Brandon Hoult 15 May '03

15 May '03

Am tryin to move from uw-imapd to dovecot, using dovecot ver 0.99.9.1-1 on debian. Using Mozilla Mail v 1.3 currently using mbox format. I made some test accounts and they seem to be working fine, but my older existing accounts give error messages whenever I connect or subscribe to mailboxes within them. The message that appears on the client is: "The current command did not succeed. The mail server responded: Invalid mask." it appears three times in an alert box (on windows) then everything seems to work. There are no messages in any of the mail logs in /var/log which would indicate a problem. The test accounts I created don't have this problem so I tried renameing the home directory, deleting the user, then recreating the user. However even with a new homedir the problem remains unchanged. I have verified that the permissions in ~/mail and /var/mail are set identically for working and non-working users. Thanks in advance for any advice, Brandon Hoult dolt(a)lmistudios.homeip.net

[Dovecot] Creating and renaming mbox folders on NFS auto-installed partitions
by Robert Evans 14 May '03

14 May '03

I'm trying dovecot-0.99.9.1 in place of uw-imap which ground to a halt on a 500MHz SunBlade 100 Solaris 8 system which acts as our Departmental mail server. INBOXes are mbox files on the servers's local SCSI disk. But user directories are auto mounted from other Sun NFS servers and these may contain other mbox mailboxes in a ~/Mail directory. There's a problem with creating (and with renaming) mailboxes in the NFS mounted ~/Mail directory. For an arbitrary mailbox "newbox", say, dovecot tries to create the parent directory path /home/username/Mail before creating the newbox file. But /home/username is automounted and so creating directory /home or /home/username fails with errno 89 ENOSYS - unsupported file system operation. The solution is to check for the existence of the directory before trying to create it. This will work since /home and /home/username will always exist for any valid user. I've amended mbox-storage.c in src/lib-storage/index/mbox to call "access" to do this.... *** src/lib-storage/index/mbox/mbox-storage.c.orig Tue Apr 15 14:04:02 2003 --- src/lib-storage/index/mbox/mbox-storage.c Wed May 14 16:04:39 2003 *************** *** 38,44 **** p++; } ! if (mkdir(dir, CREATE_MODE) < 0 && errno != EEXIST) { t_pop(); return -1; } --- 38,44 ---- p++; } ! if ( (access(dir,F_OK) != 0) && mkdir(dir, CREATE_MODE) < 0 && errno != EEXIST) { t_pop(); return -1; } - - - (Could also remove the && errno == EEXIST part - it's redundant when access(dir,F_OK) is checking for existence).

Re: [dovecot] Re: Design thought - Retention of reworked mbox files
by Tim Hunt 13 May '03

13 May '03

It's primarily for debugging, and I don't see it being used in a high volume environment. What triggered the thought is that I suspect I may have lost the bodies of a couple of messages during an expunge, but because I don't have the previous state of the mbox file, I have no way of verifying my concern, and certainly no way to try and recreate it. And yes, I'm using mbox files, because I have many years of mail stored in them, and I'm not quite ready to convert them to another format.

[dovecot] 0.99.9 released

05 May '03

As promised yesterday :) BTW. I just found libsqlora8 library yesterday and I've been playing with Oracle mail storage support. Shouldn't take too long to get it working. And the NEWS file once more: v0.99.9 2003-04-28 Timo Sirainen <tss(a)iki.fi> * WARNING: mbox rewriting works now faster, but it's less likely to notice external message flag changes (it wasn't perfect before either). This also means that if you're not using index files, Dovecot may not notice changes made by another Dovecot process. This will be fixed later. + Message UIDs are now permanently stored outside index files. Deleting indexes is now possible without any kind of data loss and in-memory indexes are now usable. + mbox rewriting leaves extra space into X-Keywords header. It's shrinked or grown when updating message flag headers to avoid rewriting the rest of the file. + imap-login and pop3-login can now be started from inetd. Privilege separation is still used, so it executes dovecot and dovecot-auth processes which are left on the background. + PostgreSQL authentication support, patch by Alex Howansky - Large multiline headers (over 8kB) broke Dovecot before. Now they're parsed one line at a time and we try to avoid reading them fully into memory. - SEARCH OR was broken - Partial BODY[] fetches were broken - Timezones were still set wrong when parsing dates - Using non-synchronized literals (LITERAL+) broke APPEND - Renaming maildir subfolders inserted extra "." in the middle. - Subfolders were a bit broken with maildir - Invalid PLAIN auth request crashed auth process.

The errors persist in the logs until I manually remove the .imap* files, which are subsequently recreated upon the next access (without the error being logged, at least not right away). I had the impression that a "Corrupted index file" would cause the index files not to be used, and in fact recreated. Apparently not? If there is an error that causes the .imap* files to be ignored, shouldn't those files be removed? mm

[dovecot] Message causing pop3 crash
by Mark E. Mallett 03 May '03

Hi- Found a message that will generate a pop3 coredump when using mbox format. It seems to do with the fact that it has a mime part with a line that's 10,000 bytes long. However, that doesn't seem to be the only factor. Adjusting the size of the mail header seems to cause different kinds of crashes. I'll avoid attaching the message here but I've put it at http://www.mv.com/users/mem/x/badmail Reproducing it here on a BSD/OS system involves something like: (login to a virgin account or one you don't care about) % wget http://www.mv.com/users/mem/x/badmail % rm -rf .imap % MAIL=mbox:`pwd`/badmail % limit coredump 10m % /usr/local/libexec/dovecot/pop3 quit at which point you should get some errors and/or a coredump. You may need to do it twice (i.e. let it create the .imap/ index structure first). If you can't make it happen I can send along more info. -mm- (and yes, this was a real mail message, albeit a spam, except that I simplified it some and replaced all of the content with "x" characters)

[dovecot] Debian packages for 0.99.9
by Jaldhar H. Vyas 30 Apr '03

30 Apr '03

I uploaded the new version to sid today. Apart from the new version a big change is that it has now been split into 4 pieces. dovecot-imapd and dovecot-pop3d are the imap server and the pop3 server rspectively. They are seperate so you can install one without the other. dovecot-common contains the files they both use. dovecot is just a dummy to ensure smooth upgrades for users of older versions. As there are new packages, they will take a while to show up i the archive so I'm temporarily making them available from http://src.braincells.com/debian/sid/dovecot/ or deb http://src.braincells.com/debian sid/ deb-src http://src.braincells.com/debian sid/ via apt-get. but unless you have a burning need to upgrade, I recommend you just wait a few days. A backport to woody is also available, add deb http://src.braincells.com/debian woody/ deb-src http://src.braincells.com/debian woody/ to your sources.list. One problem I found with installing on woody is that the first time you do apt-get install dovecot, it gives you an error because /etc/dovecot.conf is no owned by dovect-common instead of dovecot. It will work correctly the second time you run the command. -- Jaldhar H. Vyas <jaldhar(a)debian.org> La Salle Debain - http://www.braincells.com/debian/

[dovecot] Dovecot RH RPM packages
by Dag Wieers 29 Apr '03

29 Apr '03

Hi, I can't remember if I already told you, but I'm building RPM packages of dovecot for RH73, RH80 and RH9. You can find these at: http://dag.wieers.com/packages/dovecot/ Or use apt as described on: http://dag.wieers.com/apt/ I also added a sysv file to the SPEC-file for use with Red Hat. If you add this SPEC-file to your tarball (probably with some custom changes) everyone can build an RPM package by issuing: rpmbuild -ta <tarball> Kind regards, -- dag wieers, dag(a)wieers.com, http://dag.wieers.com/ -- �Any errors in spelling, tact or fact are transmission errors�

[dovecot] 0.99.9 release candidate 1
by Timo Sirainen 28 Apr '03

28 Apr '03

0.99.9 should really be released soon. There's been quite a lot of important fixes since 0.99.8.1. There's still some recent counter strangeness, but it wasn't perfect before either. mbox still doesn't necessarily notice flag changes unless they're written into index file (ie. non-Dovecots and Dovecot without index files). But it wasn't perfect before either. dovecot-uidlist file works perfectly now as far as I know. I just noticed that mbox syncing has been somewhat broken for past month. It sometimes assigned new UIDs to messages without any reason, so it was mostly just slowdown. So unless there's something really broken, I'll release 0.99.9 tomorrow. Please get 0.99.9-rc1 from http://dovecot.procontrol.fi/rc/ and see if you can break it. NEWS file: v0.99.9 2003-04-28 Timo Sirainen <tss(a)iki.fi> * WARNING: mbox rewriting works now faster, but it's less likely to notice external message flag changes (it wasn't perfect before either). This also means that if you're not using index files, Dovecot may not notice changes made by another process. This will be fixed later. + Message UIDs are now permanently stored outside index files. Deleting indexes is now possible without any kind of data loss and in-memory indexes are now usable. + mbox rewriting leaves extra space into X-Keywords header. It's shrinked or grown when updating message flag headers to avoid rewriting the rest of the file. + imap-login and pop3-login can now be started from inetd. Privilege separation is still used, so it executes dovecot and dovecot-auth processes which are left on the background. + PostgreSQL authentication support, patch by Alex Howansky - Large multiline headers (over 8kB) broke Dovecot before. Now they're parsed one line at a time and we try to avoid reading them fully into memory. - SEARCH OR was broken - Partial BODY[] fetches were broken - Timezones were still set wrong when parsing dates - Using non-synchronized literals (LITERAL+) broke APPEND - Renaming maildir subfolders inserted extra "." in the middle. - Subfolders were a bit broken with maildir - Invalid PLAIN auth request crashed auth process.

[dovecot] dovecot and grsecurity (problem with resource limits)
by Heiko Zuerker 27 Apr '03

27 Apr '03

Howdy folks ! I just added Dovecot as a standard package to Devil-Linux and ran into a problem with resource limits. Grsecurity (http://www.grsecurity.net) is used in DL to prevent problems with common exploits, it also reports violations of rlimits. The following messages show up in the log, but it seems that the IMAP Server works fine: Apr 26 19:20:04 src@gate imap-login: Login: hz [192.168.0.11] Apr 26 19:20:05 src@gate kernel: grsec: attempted resource overstep by requesting 37 for RLIMIT_NPROC against limit 0 by (dovecot:10246) UID(0) EUID(0), parent (dovecot:634) UID(0) EUID(0) Apr 26 19:22:18 src@gate kernel: grsec: attempted resource overstep by requesting 37 for RLIMIT_NPROC against limit 0 by (dovecot:19802) UID(0) EUID(0), parent (dovecot:634) UID(0) EUID(0) Apr 26 19:22:18 src@gate imap-login: Login: hz [192.168.0.11] Apr 26 19:26:36 src@gate syslog-ng[606]: STATS: dropped 0 Apr 26 19:28:19 src@gate kernel: grsec: attempted resource overstep by requesting 33 for RLIMIT_NPROC against limit 0 by (dovecot:16011) UID(0) EUID(0), parent (dovecot:634) UID(0) EUID(0) How should we proceed to analyze/fix this problem?

[dovecot] Using on AIX
by Adam Lackorzynski 25 Apr '03

25 Apr '03

Hi, I'm trying to install dovecot-0.99.9-test6 with gcc-3.2.2 under AIX (4.3.3) and found some problems. First, I need to define _XOPEN_SOURCE_EXTENDED to 1 in src/lib/fdpass.c and src/auth/mycrypt.c or undefine it to compile successfully. When I define _XOPEN_SOURCE_EXTENDED to 1, I get the following error while connecting: dovecot: Apr 21 17:56:44 Info: Dovecot starting up imap-login: Apr 21 17:57:19 Fatal: fd_send(5) failed: Bad file number dovecot: Apr 21 17:57:19 Error: child 39504 (login) returned error 89 This happens after a successful authentication (i.e. wrong authentications are correctly denied). Something similar happens if I define _XOPEN_SOURCE to 500 in both files. When I undefine the _XOPEN_SOURCE_EXTENDEDs without modifying the original _XOPEN_SOURCE defines, it seems to come further: imap-login: Apr 21 18:24:23 Info: Login: xxx [xxx.xxx.xxx.xxx] imap(xxx): Apr 21 18:24:23 Panic: file mail-index-data.c: line 439 (mail_index_data_append): assertion failed: ((size & (MEM_ALIGN_SIZE-1)) == 0) dovecot: Apr 21 18:24:23 Error: child 95800 (imap) killed with signal 6 but this doesn't work either.

[dovecot] quotas again
by Mark E. Mallett 21 Apr '03

21 Apr '03

A couple of notes about quotas-- I know this has been brought up before but the negative effects that occur when a user is over quota are still disconcerting. Ideally it would be best if a user could at least delete mail when in an over-quota condition. One would think it would be enough to simply ignore errors creating the index files (and use an in-memory index). However, another problem is that the mere renaming of a file from the new/ directory to the cur/ directory can cause an over-quota error if the cur/ directory has to be expanded. We see these errors in the maillog followed by an "I/O leak" message, e.g.: Apr 21 07:42:26 mercury mem[10059]: pop3(someuser): maildir build: rename(/users/3a/someuser/Maildir/new/1049919998.23875.mercury.mv.net, /users/3a/someuser/Maildir/cur/1049919998.23875.mercury.mv.net) failed: Disc quota exceeded Apr 21 07:42:26 mercury mem[10059]: pop3(someuser): I/O leak: 0x807361c (1) Apr 21 07:42:26 mercury mem[10059]: pop3(someuser): I/O leak: 0x804a1b8 (0) and then we get a report about the server dropping the connection. BTW we seem to see quite a lot of these "I/O leak" messages in other situations too, and I think it started with the test5 release (but I am not absolutely sure). What does this mean? Yours, mm

[dovecot] 0.99.9-test6
by Timo Sirainen 21 Apr '03

21 Apr '03

Just two fixes: - dovecot-uidlist file is now assumed to be changed if it's modify time is changed. before we relied on inode changing which isn't fully reliable. - mbox dotlocks sometimes incorrectly thought someone else had overridden them Known problems that I should fix: - mbox: we don't necessarily notice message flag changes by external programs (or another dovecot without index files). It's because we don't always reparse the whole mbox file when it has changed. I think I'll have to add some X-IMAP-Changelog header which describes what changes were made by other Dovecot processes. If the change isn't listed in that header, we'll fallback to reparsing the whole file. Although that's still a bit annoying since MTA just appends the new mails, we wouldn't really need to reparse the whole file then, just the new mails. - I should use link() instead of relying on O_EXCL which doesn't work with NFSv2 (or Linux's NFSv3 client). - .subscriptions and .customflags files still aren't NFS-safe

[dovecot] Folders with mail and subfolders
by Keith Edmunds 21 Apr '03

21 Apr '03

I have a maildir hierarchy (built originally with Courier-IMAP) where some folders contain both email and subfolders. Using Dovecot I cannot see the mail in the top folders: I can only see the subfolders. Is this an RFC restriction or a Dovecot restriction? If the latter, is it planned to change? Otherwise: just started using Dovecot, and I'm very impressed with the speed of it. Thanks! Keith

[dovecot] 0.99.9-test5
by Timo Sirainen 21 Apr '03

21 Apr '03

- Fixed startup crashing in POP3 server - Several fixes to opening index file which needs to be rebuilt. Before it didn't always rebuild the index but just fallbacked to using only memory, and that could have been quite slow since all mails in the mailbox were opened and parsed. - If there's nothing in mail_cache_fields, index rebuilding doesn't open the file anymore. This should make in-memory indexes a lot faster than before, but it could also mean some performance hits later. If client wants to fetch all mails from the mailbox, the same thing has to be done anyway.. This needs more thinking actually what is the optimal behaviour. - Support /etc/shadow-like file for passdb.

[dovecot] Message with lots of attachments breaks Dovecot
by Tim Hunt 21 Apr '03

21 Apr '03

I have a message with over a 1000 embedded attachments(!), and it breaks Dovecot. The issue appears to be buffer management. There is some logic in the function message_part_deserialize_part that seems to assume that the message part structure is in a contiguous array, but that doesn't seem to be the case. I haven't been able to figure out enough about the memory management in Dovecot to fix the problem. Below is a horrible workaround that just allocates a lot more memory for the message part array, so that it remains contiguous. *** mail-index-update.c.orig Wed Mar 26 10:41:55 2003 --- mail-index-update.c Sun Apr 20 16:53:45 2003 *************** *** 498,504 **** if (cache_fields & DATA_FIELD_MESSAGEPART) { t_push(); ! buf = buffer_create_dynamic(data_stack_pool, 2048, (size_t)-1); message_part_serialize(part, buf); --- 498,504 ---- if (cache_fields & DATA_FIELD_MESSAGEPART) { t_push(); ! buf = buffer_create_dynamic(data_stack_pool, 51200, (size_t)-1); message_part_serialize(part, buf);

[dovecot] Corrupt mbox handling
by Kristian Hoffmann 17 Apr '03

17 Apr '03

I've found that if an mbox file has two consecutive 'From' delimiters, I get the error: pop3(user): Error indexing mbox file /var/spool/mail/user: LF not found where expected UofW apparently ignores the second 'From' silently. I've been trying to run dovecot in gdb to get more details on exactly what is happening, but I haven't quite mastered the art of attaching to the pop3 process between the login process completing and it exiting. Is there some trick to doing that? If I can't work around it in dovecot, I can just write something in perl to fix all the duplicate 'From' lines.

[dovecot] PATCH Add support for kqueue in ioloop subsystem
by Dominic Marks 16 Apr '03

16 Apr '03

Hey, I noticed that there was an ioloop "module" (if we can call it that) for select and poll and decided to add one for kqueue (aka kevent) BSDs high performance descriptor multiplexing API. I haven't done any of the configure glue stuff but the code is complete and works well. kqueue is available on all recent versions of FreeBSD, NetBSD, OpenBSD and Darwin (and therefore MacOS X). I've tested both pop3 and imap with no problems. To get it working: (bodge method) > tar zxvf dovecot-0.99.8.1.tar.gz > cp ioloop-kevent.c dovecot-0.99.8.1/src/lib/ > cd dovecot-0.99.8.1/ > ./configure > vi config.h 1. replace IOLOOP_POLL (or IOLOOP_SELECT) with IOLOOP_KEVENT > vi src/lib/Makefile 1. find liblib_a_SOURCES add ioloop-kevent.c to it 2. find liblib_a_OBJECTS add ioloop-kevent.$(OBJEXT) to it > make There is a paper on kqueue which includes a performance evaulation here: http://people.freebsd.org/~jlemon/papers/kqueue.pdf Thanks, -- Dominic <dom at cus.org.uk> <d.marks at student.umist.ac.uk>

I don't know the exact reason bu I assume dovecot is regenerate everybody's index a other cache at the same time. is there any way to reduce the possible number of IO load? this would be useful if never happend again!:-) this happend around 4:40. the output of sar -b: -------------------- 03:00:00 PM tps rtps wtps bread/s bwrtn/s 03:10:00 PM 48.18 29.19 18.99 1456.53 771.29 03:20:00 PM 41.66 25.80 15.86 1054.88 830.05 03:30:00 PM 42.64 25.67 16.97 1223.03 759.77 03:40:00 PM 44.98 31.95 13.03 1959.15 467.40 03:50:00 PM 26.68 14.63 12.05 741.48 424.12 04:00:00 PM 25.80 11.70 14.10 516.21 450.04 04:10:00 PM 59.55 34.91 24.64 1755.07 939.11 04:20:00 PM 95.98 61.15 34.83 4453.24 1563.25 04:30:00 PM 95.08 55.45 39.63 2182.22 1591.56 04:40:00 PM 168.85 145.99 22.86 11155.73 1037.25 04:50:00 PM 135.98 106.50 29.48 7908.21 1604.76 05:00:00 PM 125.87 97.65 28.23 5876.03 1060.50 05:10:00 PM 80.83 62.92 17.90 4321.82 590.19 05:20:00 PM 102.04 77.65 24.40 4907.27 1076.92 05:30:00 PM 129.04 106.58 22.46 6387.18 883.13 05:40:00 PM 89.44 73.20 16.24 4905.64 782.94 05:50:00 PM 88.23 73.16 15.06 5539.93 965.34 06:00:00 PM 92.49 72.67 19.81 5486.25 692.18 06:10:00 PM 45.24 32.82 12.42 1711.35 618.31 06:20:00 PM 42.17 28.16 14.01 960.11 622.33 06:30:00 PM 29.90 20.24 9.66 1538.27 376.17 06:40:00 PM 25.89 12.14 13.74 796.73 833.25 06:50:00 PM 20.50 4.98 15.52 264.91 993.62 07:00:00 PM 15.08 7.57 7.52 453.41 282.63 -------------------- the output of sar -d -------------------- 04:10:00 PM dev22-3 0.00 0.00 04:10:00 PM dev33-0 1.76 109.55 04:10:00 PM dev34-0 8.51 919.94 04:20:00 PM dev3-0 8.56 183.93 04:20:00 PM dev22-2 67.62 3798.02 04:20:00 PM dev22-3 0.00 0.00 04:20:00 PM dev33-0 4.80 463.81 04:20:00 PM dev34-0 15.01 1570.73 04:30:00 PM dev3-0 4.40 126.63 04:30:00 PM dev22-2 77.02 2440.08 04:30:00 PM dev22-3 0.00 0.00 04:30:00 PM dev33-0 1.94 124.80 04:30:00 PM dev34-0 11.73 1082.28 04:40:00 PM dev3-0 4.78 124.56 04:40:00 PM dev22-2 137.27 10306.18 04:40:00 PM dev22-3 0.00 0.00 04:40:00 PM dev33-0 13.50 410.44 04:40:00 PM dev34-0 13.29 1351.80 04:50:00 PM dev3-0 6.33 194.27 04:50:00 PM dev22-2 111.50 7961.44 04:50:00 PM dev22-3 0.00 0.00 04:50:00 PM dev33-0 5.64 156.51 -------------------- -- Levente "Si vis pacem para bellum!"

[dovecot] Shadow password file
by Jaime Medrano 16 Apr '03

16 Apr '03

¿Is there any way to make dovecot to take the passwords from a file with a shadow password format? I've tried with the passwd-file auth plugin, but it complains that users have uid=0 Thanks in advance, Jaime Medrano

[dovecot] it seems to unusable
by Farkas Levente 16 Apr '03

16 Apr '03

hi, is there any way to turn off the whole indexing stuff? unfortunately the system getting totaly unusable beacuase of the high load and the mail index generation is so slow that every users call the helpdask that his mail is not working (what's more in this case just click on OE again and start another mailer process:-() we've got about 100k mails which is about 10-20GB! -- Levente "Si vis pacem para bellum!"

[dovecot] pop3 coredump
by Mark E. Mallett 16 Apr '03

16 Apr '03

Hi- I was able to get a coredump out of the new pop3 (from 0.99.9-test4) by attempting to simulate the execution environment and simply running the pop3 program. Running the older pop3 from 0.99.8.1 works fine, repeatedly: % /usr/local/libexec/dovecot/pop3 quit +OK Logging out. However running the new one: % /usr/local/libexec/dovecot/pop3.new pop3(user9): Error: Corrupted index file /users/48/user9/Maildir/.INBOX/.imap.index: index.next_uid (4539) > uidlist.next_uid (4000) Segmentation fault (core dumped) It doesn't always dump core even with this message. The error message is not always the same, but it's usually what's above. Simply repeating the invocation a number of times I also saw: pop3(user9): Error: Corrupted index file (in-memory index for /users/48/user9/Maildir): Filename mismatch for UID 1: 1050440153.17005.mercury.mv.net vs 1050437948.5418.mercury.mv.net Here's some gdb output corresponding to the coredump above. -mm- Script started on Tue Apr 15 16:51:28 2003 % gdb pop3/pop3 pop3.core ...

[dovecot] PATCH allow_zero_gid option
by Dominic Marks 15 Apr '03

15 Apr '03

Hey, Well, that was easy :-) Patch against CVS follows: Summary: Created a boolean option allow_zero_gid, when set to yes it will allow logins from users whose group id is zero. Tested with KMail 3.1.1 on FreeBSD 4.8. I'm not sure if my method for passing the boolean via the environment is correct, it looks a little on the ugly side.

[dovecot] Group ID validation and FreeBSD
by Dominic Marks 15 Apr '03

15 Apr '03

Hey, I've been working on making the Dovecot FreeBSD port resemble something which actually works this weekend, it's now much improved - one thing that I did notice is that Dovecot validates a users GID and will not accept a group id of 0. In FreeBSD the group wheel has a the id 0 and only members of the wheel group are allowed to use su and become root. Consequently there are non-root users who have group id's of 0. When you try and open the mailbox of such a user with Dovecot the connection is killed immediately. It would be excellent to have an option in dovecot.conf along the lines of allow_zero_gid which would disable these checks. From a quick look at the source I can see that the validation is being done in src/master/mail-process.c and that src/lib/restrict-access.c is also involved. If I can get a working patch ready quickly I'll pass it along. If anyone would like to take a look at the port you can get a copy at the following address: http://cus.org.uk/~dom/dovecot-0.99.8.1.shar.gz Hopefully this will go into FreeBSD CVS quite soon. Thanks, -- Dominic <dom at cus.org.uk> <d.marks at student.umist.ac.uk>

Crash notice in mail.log: Apr 13 17:36:12 rafter dovecot: child 23215 (imap) killed with signal 11 My `dovecot --version` says: 0.99.8 Has this problem been fixed in current dovecot? For now I have just quarantined the offending message but obviously I need to upgrade my dovecot soon because I don't like such kinda things to happen. best regards! -- MW

[dovecot] Three *very* strange bugs
by Warren Togami 15 Apr '03

15 Apr '03

* Attached is a mbox file that triggers Bug #1 and #2. * Go here if you want to test dovecot for RH9: https://bugzilla.fedora.us/show_bug.cgi?id=160 * If somebody has a different IMAP server than dovecot, could you please test how Evolution reacts to reading this message? Bug #1 dovecot and #2 evolution-1.2.3 ===================================== I am using dovecot-0.99.9-test3 on RH9, reading mail with evolution-1.2.2-5 on RH9. Whenever I attempt to view this one particular spam message, evolution pops up an error like: Error while 'Retrieving message 4': Server unexpectedly disconnected: No such file or directory Simultaneously this appears in my /var/log/maillog: Apr 15 01:44:50 server dovecot: child 20328 (imap) killed with signal 11 If I attempt to keep reading mail, it logs in again to dovecot and works normally until I attempt to read that spam again. Evolution displays the error popup again though I don't see another signal 11 in maillog. After this point I am unable to log back into dovecot without restarting the daemon. Here's the strange part... I browsed the same IMAP folder from KMail, and kmail has no problem reading that spam message. dovecot's [imap] process does not segmentation fault. Does this mean an evolution bug when reading this particular spam exposed a dovecot segmentation fault? Bug #3 kernel? ============== This is an unrelated bug and perhaps not the fault of dovecot. When I attempted to use strace to get some debugging info on the [imap] process, this happened: [root@server /]# strace -p 20486 trace: ptrace(PTRACE_SYSCALL, ...): Operation not permitted detach: ptrace(PTRACE_DETACH, ...): Operation not permitted [root@server /]# This isn't normal right? After doing this, dovecot stops working and I need to restart the daemon in order to establish new connections. That [imap] process becomes unkillable, even kill -9 wont work. Unkillable process usually means kernel bug, right? warren 20345 1 7 01:46 ? 00:00:34 [imap] This is kernel-2.4.20-9 in Red Hat Linux 9. Is dovecot exposing a Red Hat kernel bug when I try to strace that process, or is strace supposed to fail, the dovecot daemon ceases to function and [imap] process becomes completely unkillable? =) Warren Togami warren(a)togami.com

[dovecot] dovecot RPM for Red Hat Linux
by Warren Togami 14 Apr '03

14 Apr '03

http://bugzilla.fedora.us/show_bug.cgi?id=160 This .src.rpm is dovecot with RH-specific default settings. I modified Jeremy Katz' dovecot-0.99.8.1 package a bit. When I upgraded from 0.99.8.1 it seemed to be broken until I looked at /var/log/maillog. There it indicated that the dovecot cache files were bad, so I erased /home/*/mail/.imap/ and it seemed to work subsequently. There are a few more RH specific tweaks that I plan on doing for this package. If you have any suggestions to default config tweaks for this package please reply or post in that bugzilla entry above. I would like for this package to be a drop-in replacement for RHL's uw-imapd eventually, but there are a number of migration issues that need to be addressed first. This package will eventually be included in the Fedora tree after it goes through our QA. http://www.fedora.us Fedora Linux is a project of volunteer package developers making 3rd party packages specifically for Red Hat Linux. Warren Togami warren(a)togami.com p.s. Keep up the good work. I absolutely love dovecot!

[dovecot] Something wrong in SSL ?

[dovecot] Maildir problem?
by Maikel Verheijen 11 Apr '03

11 Apr '03

Hey list, Today I cvs updated to the most recent dovecot, to test with the recent improvements on the dovecot-uidlist file, and came acros the following: Apr 11 12:49:36 pc-5-046 imap(): Corrupted index file (in-memory index for /var/mail/mounted/test.com/maikel/Maildir//.Sent Items): Filename mismatch for UID 1: 1050058115.P3401Q0M675362.pc-5-046.test.nl:2,S vs 1050057888.P3371Q0M138398.pc-5-046.test.nl I am using a front-end back-end construction, But I am testing on the backend only (non-nfs), because the subscriptions file isn't nfs safe yet. shouldn't the uidl files be leading over the indexes? And shouldn't the indexes be updated as well? Thank you, Maikel Verheijen.

[dovecot] Maildir syncing rewrite
by Timo Sirainen 11 Apr '03

11 Apr '03

It finally seems to be working. I've done some testing now and it seems to be working fine. If you have time, see if you can get it to break (especially with INDEX=memory or by manually modifying the maildir). The UIDs are kept in Courier-compatible dovecot-uidlist file (so "mv courierimapuiddb dovecot-uidlist" should work). The great thing about this code is that we never wait for lock. If we can't lock, we simply use the old uidlist file to sync whatever we can, which should be everything but the very newest mails just being delivered and processed by another Dovecot. Of course, if they share index files, we're still blocking there. I named the file as "dovecot-uidlist" instead of ".uidlist" because I finally realized that files beginning with dot conflict with the mailbox namespace. I should rename .customflags and .subscriptions files as well. Also if I move .imap.index* files into root dir, I'll have to rename them too. new/ directory is now scanned every time to see if there's new mail. cur/ directory is scanned if index file's timestamp differs from cur/ dir's timestamp. uidlist file is reread if it's device/inode changes. You can get the sources from either CVS, or 0.99.9-test2 from http://dovecot.procontrol.fi/test/

[dovecot] compilation errors
by Mark E. Mallett 11 Apr '03

11 Apr '03

Hi- I always encounter the same two minor compilation issues which are easily addressed simply by a quick edit, but this time I figured I'd mention it in case you can work around it. This is on a BSD/OS 4.2 system. First, the generated config.h always creates a definition for OFF_T_MAX which conflicts with the one in the system's limits.h config.h defines: #define OFF_T_MAX LLONG_MAX whereas /usr/include/machine/limits.h defines: #define OFF_T_MAX UQUAD_MAX /* max value for an off_t */ I simply comment out the definition from config.h . Second, in src/lib/mmap-anon.c there's a preprocessor conditional: #if SSIZE_T_MAX >= LLONG_MAX (etc) Unfortunately /usr/include/machine/limits.h defines LLONG_MAX thusly: #define LLONG_MAX (__extension__(9223372036854775807LL)) (evidently to suppress pedantic warnings about the gcc long long constant extension) but the cpp prepreprocessor stumbles over this comparison. This might be fixed in a later gcc, I dunno- it's gcc 2.95.2 here. Yours, -mm-

[dovecot] New installation - error 89 on connect
by David Knudsen 09 Apr '03

09 Apr '03

I've recently installed dovecot (0.99.8.1) from the Debian/woody backport at 'deb http://src.braincells.com/debian woody/' Previously, all mail have been delivered to mbox'es in ~/Mail by exim/procmail -- ~/Mail/inbox being my main mailbox. Whenever I attempt to connect with an IMAP client, the connection is closed and the following error is reported in /var/log/syslog: imap-login: Login: dk [192.168.0.2] imap(dk): Unknown client workaround: outlook-idle^I### dovecot: child 17653 (imap) returned error 89 What does error 89 signify? My current configuration is: (non-comment lines only) imap_listen = 192.168.0.2 imaps_listen = * login = imap login = pop3 verbose_proctitle = yes client_workarounds = oe6-fetch-no-newmail outlook-idle mailbox_check_interval = 60 auth = default auth_mechanisms = plain auth_userdb = passwd auth_passdb = pam auth_user = root auth_verbose = yes In my confusion, I blindly tried changing settings, attempting to get a different error message at least. :-) These are the settings I have tried, without success: default_mail_env = mbox:~/Mail:INBOX=~/Mail/inbox mail_full_filesystem_access = yes mbox_locks = fcntl auth_passdb = shadow There is no subdirectories in ~/Mail, neither visible nor hidden. I did try to read the docs, and I did browse the mailing list archives, but either I missed something or it is not there. Any ideas? Thank you, David Knudsen

It should look into ~/Maildir first, then ~/mail and ~/Mail unless it's overridden in MAIL environment. You probably have MAIL=/var/mail/user set, which is why it looks into there. Currently it doesn't read any configuration file, and I'm not sure if I should make it do that.. Well, it could be useful but I'd have to figure out how to prevent unneeded code duplication for config file parsing. All settings are passed via environment settings, but they're not documented (they're basically uppercased versions of the setting names in config file). > Should I have found all of this in some documentation?

There's the "imap" binary that should do exactly that. Usually installed into /usr/local/libexec/dovecot/imap Or did you mean you wanted to run it from inetd? CVS version supports that too if you execute imap-login.

[dovecot] Mbox spool; dovecot rewriting and rewriting and rewriting
by Ask Bjoern Hansen 08 Apr '03

08 Apr '03

Hi, jaldhar recommended dovecot to me - http://www.askbjoernhansen.com/archives/2003/04/07/000286.html ... and so far it seems much nicer than the other imapds. yay. I use the OS X Mail.app client. I tested it with a test account with no problems, but trying to use it with my usual mail folders (~1.3GB; 120MB in the inbox) it's not working at all. It seems like dovecot keeps copying the full inbox into a temp file in mail/.imap/INBOX. It did it at least 10 times while I was watching without any noticable progress doing anything at all in Mail.app. I am running FreeBSD on an ancient box with 384MB ram (but nice SCSI drives). I tried stopping new mail deliveries to the inbox while I testing, but it didn't seem to make a difference. - ask -- ask bjoern hansen, http://www.askbjoernhansen.com/ !try; do();

[dovecot] Why can't hierarchy sep be changed?
by Timo Sirainen 08 Apr '03

08 Apr '03

>From: Charlie Brady <charlieb(a)e-smith.com> There's something wrong with manually accepting posts from non-subscribed addresses now, they're just left to queue directory for some reason.. Please try to keep the From-address the same as the subscribed one. > >From maildir-storage.c: > > ... > '.', /* hierarchy_sep - can't be changed */ > ... > > Why can't it be changed? Is this just for courier compatibility, or is > there a deeper reason why it can't be changed? Actually I'm going to change it to '/' to allow folders such as shared/timo.sirainen/mailbox. The directory names themselves will still contain '.' separator to stay compatible with Courier's Maildir++ format. So even though new IMAP separator will be '/', '.' still can't be used in mailbox names.

[dovecot] a few other problem
by Farkas Levente 07 Apr '03

07 Apr '03

hi, I still has a few other problem with dovecot and mozilla. - when I open mozilla mail I can only see the toplevel folders in the left handside folder list and when I close the imap folder and open it again (click on the arrow left to the imap server in the folder list) mozilla show me all folders and subfolders correctly (but not at the startup). it can be mozilla's bug, but this was worked when I use courier?! - when I'd like to sort the messages by thread than the thread is usualy ok, but I'd like to see the the different threads sorted by date (as it was while using couirer or cyrus) but now it seems to me random:-(( it's very anoying. my be it's mozilla fault again, but may be mozilla use server side thread support. - in OE6 when we only select headers only sometime some message "disappear"! which means we see in OE6 a red line over the message (as it would be deleted), but no one delete it (yes I know you don't belive me, I also don't belive our users, but once I saw it). just click on it to see the message and inmediately become as deleted. while when I look at in the server the file is still there and _not_ deleted. and OE6 show "the message already removed from the server". - what about the ssl (imaps) problem? yours. -- Levente "Si vis pacem para bellum!"

So in a way, a lot of info COULD come from my database, if it isn't safe enough via nfs. Can you make all file locking configurable? Or will you do it on a "per-type" basis?

Hi I'm trying to figure out how to set default_mail_env to support such config: INBOX is in '/var/mail/%u/' (note last slash at the end, %u is an folder with new/tmp/cur subdirs - standard maildir structure). Other imap folders are stored as files (in mbox format) in direcotry '%h/Mail/'. Please advise.

[dovecot] Question about the password field in a postgresql database
by Maikel Verheijen 03 Apr '03

03 Apr '03

Hi List, When I try to set the default_pass_scheme in dovecot-pgsql.conf to CRYPT, the dovecot does not recognize my crypted passwords. If I prepend my encrypted passwords with {CRYPT}, dovecot DOES recognize it. (even when I set default_pass_scheme to PLAIN). Is this supposed to work, or am I misinterpreting things here? Thank you!

[dovecot] Failure in the presence of too many connections
by Mark E. Mallett 02 Apr '03

02 Apr '03

Had an event today where dovecot refused new connections and would not accept more until restarted, whereupon it worked for a few minutes and locked up again. Looking at the logs it appeared that it had run out of file descriptors. I increased the open files limit and started it again-- which worked but it only pushes off the problem. Does dovecot keep an open file descriptor for every imap or pop3 child? If so, this would argue more towards a tcpserver sort of control. If not, perhaps something is leaking.. -mm- PS: assume you saw recent RFCs 3501 and 3502 ?

[dovecot] NFS mounted IMAP dirs
by Maikel Verheijen 31 Mar '03

31 Mar '03

Hi list, I am trying to build an email system that is using multiple frontends, to a clustered backend using nfs. The backend mounts his filesystems from a central storage, and will be running active-active. While reading through the dovecot documentation, I read that I could do without indexes (well: use memory indexes), and could then be able to run dovecot over NFS. Well: that was until friday, when I was reading a little bit better through nfs.txt. :) My problem is now that dovecot writes it's subscriptions to the mailstore. Since I want as little difference between my frondends as possible, (and as static as possible), I would love to see dovecot handle subscriptions in a database, or perhaps a nfs-safe file. Since I am only a junior programmer (my code is really not far from "Hello world", although I am trying to find some time to teach myself more), I might not be able to be of much assistance to you all in coding stuff, but I am willing to help out where-ever possible. Can anyone help me solve my problem in any way, and how can I contribute as well? Thank you all, Maikel Verheijen.

[dovecot] Dovecot and Quotas

Is there anything that can be done so that when users IMAP to their inbox and have reached their filesystem quota, that they can still DELETE their mail? They can login, but when they go to delete/expunge this is the error I get in syslog. I have tried mail_read_mmaped to yes and no, and same result.

Maybe there could be a "toggle" to do or don't create the dirs, so you don't need the mail_global_dir setting for "normal" use. My idea was to check the full path to the mailbox, and to create the nonexisting part if necessary. At that point you DO have the full path to the mailbox/maildir, and you can create it, right? Kind regards, Maikel Verheijen.

[dovecot] inetd/xinetd/tcpserver support
by Timo Sirainen 26 Mar '03

26 Mar '03

I was just thinking how they could be easily supported. This would work, right? : imap stream tcp nowait root /usr/sbin/tcpd /usr/local/libexec/dovecot/imap-login imaps stream tcp nowait root /usr/sbin/tcpd /usr/local/libexec/dovecot/imap-login --ssl imap-login would try to connect to master process using some named socket. If it couldn't, it would create the master process itself. Master process would work as usual (executes auth and imap processes), except it wouldn't be executing login processes. This wouldn't require much code changing, and it would still be using all the same privilege separations as the standalone version so it would be just a secure. Only thing I'm wondering is if any of the TCP wrappers care about the created child processes? The master process would have to stay alive after the connection that created it dies. I guess I'll implement this soon and try if it works.

[dovecot] mailbox problem
by Maikel Verheijen 26 Mar '03

26 Mar '03

Hi list! Since a week I am testing with dovecot, and I must say, I like it a lot :) Keep up the good work :) I do have one questing regarding dovecot: If I login to a mailbox, and the mailbox does NOT exist, and the parent directory does not exist either, I will get disconnected, and dovecot claims it cannot create the directory. (eg: my user blah(a)test.com has mail directory /var/mail/t/te/test.com/blah/Maildir, and all directories up to /var/mail/t/te/ exist, dovecot does not create the directory test.com/ and on.) Is this by design, or should this be created by dovecot? The problem is solved as soon as the user receives his first email, since my MTA creates the directories... Thank you, Maikel Verheijen

Hi to all, We are a bit of newbes to imap etc, so may be we just not doing it right. Nevertheless, We have compiled dovecot to run under Solaris 8/9 for IPv6 test. We are going crazy. After a successful compilation, the troubles really began. Solaris 9 1. Every´time we reboot- the directory /var/run/dovecot/auth is gone ???? 2. After the dir is created manually, the server starts. However!!! 1. A telnet to host 143 connect to the server fine but no commands are accepted. The server simply returns "bad command" 2. If we try to connect via a e-mail client to the server - we get a login refused - which I suspect is simply the "bad command" error being interpreted as such. We have tried every concivable combination of conf items in the conf file but nothing. Solaris8 Just does not start.

[dovecot] some problem with dovecot
by Farkas Levente 21 Mar '03

21 Mar '03

hi, yesterday we switch to courir to dovecot the whole company. there is good and bad news. the good one that about 200 people use outlook and outlook works fine (after we make some registry hack to delete the INBOX form imap root folder, which was required for courier but not for dovecot). the bad news we try most of the thing before the switch except outself. since the whole it department use linux and mozilla. and almost nothing is working with mozilla: - first of all the folder list can't be subscribed i.e. only the top level folder can be subscribed. can't subscribe to folder which has subfolders and mail inside. all folders with has subfolders shonw as an empty name folder under itself. and you can't select these folders in mozilla's subscribe window (i.e you are not able to check it even it is there). - you can't send any messages!!! since mozilla can't find the Sent folder and can't move the mail after sending!!! even if you reconfigure mozilla to use that "Sent" folder as Sent folder. - you can't see the mails in a folder which has subfolders i.e. it seem there is no message in that folders. - we store mails in ~/Maildir/. dovecot create a ~/Maildir/.INBOX and put the index files of the ~/Maildir/{cur,new,tmp} into that folder but for all other folders it keep the index files in that folder's directory. it's realy confusing. this is _very_ anoying:-((( is there any dirty trick to use mozilla? when thses will be useable? thanks.

The package for sid was uploaded last night and should appear in the archive today. A backport for woody is available from http://www.braincells.com/open/ I have not included POP3, LDAP or SASL2 support for now as I didn't want anything to delay the package from entering the archive. That will be the next order of business. The only bug I've seen so far is that when my mbox-format inbox was in /home/jaldhar/mail/inbox dovecot thought it ha 0 messages. It only showed up properly after I moved it back to /var/spool/mail/jaldhar but I suspect this is just a configuration error on my part. -- Jaldhar H. Vyas <jaldhar(a)debian.org> It's a girl!

[dovecot] big mail problems..
by Jesse Peterson 19 Mar '03

19 Mar '03

Attachments, large mails & etc. seem to have problems with my installations of dovecot. As we know, Mozilla likes to take it's mail in chunks, and after Mozilla, (or Mail.app, it likes to do this, too) takes its first chunk, it doesn't start getting the rest, even though ethereal tells me that dovecot OK'ed the 10K chunk. 9 UID fetch 4 (UID RFC822.SIZE BODY[]<0.10240>) * 4 FETCH (UID 4 RFC822.SIZE 3958069 BODY[]<0> {3958069} <snip> 9 OK Fetch completed. Nothing gets transfered beyond this point. I think this would be mozilla's fault, but I dont think this would happen with a release, and I dont think Mail.app would have the same problem, too.

Hi everyone I have been trying to get Dovecot installed with OpenSSL support, but no matter what I do, when I run Configure, it says "Building with SSL support.........No". I have even tried configure --with-ssl=openssl, to no avail. I have built and installed OpenSSL, and libssl.so and libcrypto.so are in the /lib directory - what more does Dovecot want? I have tried figuring it out from the Configure script itself but it's cryptic and I am no shell script boffin!

[dovecot] dovecot/vpopmail auth problems
by Chris Doyle 15 Mar '03

15 Mar '03

Hello. I am having problems getting dovecot to authenticate correctly through vpopmail. I have used vpopmail for some time, and I understand how it works. vpopmail is using mysql to store it's authentication data. vpopmail's tools can access the user database just fine, and vchkpw is working so far as authentication goes. I took an "strace -f dovecot", in case it can help. It is about 900k, and can be accessed at http://www.narshe.net/~umaro/dovecot.log please help! Thanks Chris Doyle

[dovecot] Shared Folders?
by Moe Wibble 14 Mar '03

14 Mar '03

Hello everybody (esp. Timo ;)), in an attempt to replace our cyrus imapd with something less bloated I have recently evaluated some of the younger imapd implementations, namely bincimap and also dovecot. Bincimap didn't work properly with mozilla for me, dovecot hasn't failed on any test, yet. Unfornationally, since we have been using cyrus for over 1.5 yrs, we pretty much depend on the "shared folders"-feature. Are there any plans to make shared folders available in dovecot anytime soon? best regards! -- MW

[dovecot] Starting Dovecot?
by Leslie Viljoen 13 Mar '03

13 Mar '03

Hello! I have laid SSL aside for the time being, and continued compiling and installing Dovecot. Now I don't know how to start it! I have been through the config file and mostly left things as-is. I have created the dovecot user and group and put only dovecot user in the dovecot group. Then I tried imap-master, as specified in the INSTALL documentation, but there is no such file! Under src/master, "dovecot" gets built. I tried running this, and /var/log/messages says "dovecot starting", but this process seems to just end. If I run it twice very quickly, I get told that port 143 is busy - so it seems that it is starting up, but only staying up for a very short while. Messages gives no more clues as to why the server quits. Any ideas? Les PS: I am trying dovecot 0.99.8.1. ______________________________________ Leslie Viljoen Africa Missions Systems Administrator Cell: 0836186100 Work: 011 6991700 Fax: 011 7945522

[dovecot] SMTP options
by Jesse Peterson 13 Mar '03

13 Mar '03

I realize this is not an SMTP discussion list, but... here goes: This is my situation. We have mobile users that need a secure (SSL) SMTP+auth gateway that simply forwards rfc822's to our real MTA. All it would have to do is accept SSL connections, authenticate the user, accept his message, then send that to the MTA. Anybody know of a very minimal software package that can do this? -- Jesse Peterson / jesse(a)pixeltechs.com

[dovecot] 0.99.8.1 out

11 Mar '03

Nothing but bugfixes from CVS: * src/lib-storage/index/mbox/mbox-list.c: mbox: LIST "" invalid-directory/% doesn't anymore give internal error * src/lib-storage/index/index-fetch.c: FETCH: \Seen flag updating didn't work (eg. FETCH BODY[]). * src/lib-imap/imap-parser.c: Literal parser broke if \r\n wasn't in buffer at the time '}' was parsed. * src/lib-mail/message-address.c: message_address_write() didn't work. * src/lib-mail/message-address.c: message_address_parse(): allow using data_stack_pool (above two fix SEARCH FROM, TO, CC, BCC crashing) * src/lib-storage/index/index-save.c: Don't crash if something tries to write 0 bytes in headers while saving the message. This happened sometimes with mbox. * src/auth/master-connection.c: Don't crash if auth request wasn't found. * src/lib/failures.c: Handle /dev/stderr directly instead of open()ing. * src/lib-imap/imap-quote.c: Use literals for strings containing '"' and '\' characters too. This wasn't done at all before so FETCH ENVELOPE, BODY and BODYSTRUCTURE could have returned pretty broken results. * src/lib-storage/index/mbox/mbox-storage.c: Selecting INBOX didn't use index files if full_filesystem_access was yes. * src/auth/db-ldap.c: Setting user_global_uid or user_global_gid crashed. * src/lib/safe-mkdir.c: safe_mkdir(): usage fchmod() and fchown(). chmod() wasn't really safe and lchown() wasn't portable. * src/auth/mech-plain.c: Invalid PLAIN auth request crashed auth process. * src/master/main.c: [::] address wasn't treated exactly as "ipv6 any", but looks like gethostbyname() worked with it. * doc/nfs.txt: updated * doc/index.txt: update

[dovecot] Apple's Mail.app
by Scott A.McIntyre 10 Mar '03

10 Mar '03

Hi, I solved the OSX Authentication issue; I'm now reliably able to get authenticated using the Password Server with PAM with: # login: auth account password session auth required pam_nologin.so auth sufficient pam_securityserver.so auth sufficient pam_unix.so auth required pam_deny.so account required pam_permit.so password required pam_deny.so session required pam_permit.so As the /etc/pam.d/imap Anyway -- new problem. With Apple's Mail.app and how it wants to download messages into it's cache, I've found that there's a problematic interaction between Dovecot and Mail.app -- but pinning down exactly what and where is proving to be a hassle. I was running Courier-Imap with Mail.app, and that worked without incident (however, the courier-imap server was on Linux, not OSX Server, that will not work (yet) with osx-server). If I use Entourage and Dovecot, it works fine. The primary symptom is that as it downloads messages Mail.app just hangs; no response, the session just freezes. Usually it's when the status bar is saying something akin to "Caching 9 of 506" at which point it stops. The number varies, but it's always in the first couple of dozen. Messages are small, so it's not that it's hanging on a large mail download. I eventually have to forcibly kill Mail.app. The log says nothing of use: dovecot: Mar 07 17:31:23 Info: Dovecot starting up imap-login: Mar 07 16:32:50 Info: Login: scott [194.109.29.21] imap-login: Mar 07 16:33:46 Info: Login: scott [194.109.29.21] imap-login: Mar 07 16:35:38 Info: Login: scott [194.109.29.21] But perhaps there's a more verbose option somewhere. Thoughts? Scott

[dovecot] IMAP Folder paths
by Juergen Kahnert 07 Mar '03

07 Mar '03

Hello, we like to use dovecot, but our old imapd used to store the paths of the folder in the file ~/.mailboxlist. This file contains something like this: mail/read mail/dovecot .netscape/imap/mailbox .Mail/foo Each line with a path to one mbox folder. And please pay attention that there is no path to the inbox, because this is stored on the server... Is there a way to use this files with dovecot? It would be a real pain to change this for a few thousand user... Do you see a chance of using such a file? Or is it already possible and I'd overlooked it? Or is it easy / hard to implement? kind regards, Jürgen Kahnert

[dovecot] OSX & Authentication
by Scott A.McIntyre 07 Mar '03

07 Mar '03

Hi, Taking a stab at getting OSX Server 10.2.4 running Dovecot -- with a minor tweak of replacing lchown() with chown() in the src/lib/sakfe-mkdir.c, it compiled and installed without any problems. However, oddness in authentication. It works once, but only once. I'm trying to use pam and have the following: auth required pam_securityserver.so auth sufficient pam_unix.so account required pam_unix.so In the dovecot.conf I have (amongst other things): auth_userdb = passwd auth_passdb = pam I start up dovecot and do: Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK dovecot ready. . login scott pass . OK Logged in. . logout * BYE Logging out . OK Logout completed. No problem. However, try it again and: Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK dovecot ready. . login scott pass . NO Authentication failed. . logout * BYE Logging out . OK Logout completed. Perhaps there's a better way to get dovecot playing under osx; I'd tried a number of ways of using pam, but perhaps there's a magic other option I've not got working yet. I do run the password server and my account name is using that as per the Workgroup Manager's settings (as opposed to Basic)... Any thoughts appreciated! Scott

[dovecot] Torture tests
by Ian R. Justman 04 Mar '03

04 Mar '03

Hi, all. I've been so impressed with Dovecot, I'm in the process of moving my mail over to it. In fact, one of my mailboxes got SO huge, it'll likely literally take more than a day to move it all over (in excess of 19,000 mails, about 140 megabytes). So far, the IMAP server shows absolutely no sign of crapping out yet. It should also be noted that I'm moving all this mail out of a Cyrus mailstore into an mbox folder on the same server using Pine. And at work, for my work mail, I recently installed Dovecot 0.99.8, using the POP2 port so I can have test it out while not disturbing my coworkers' ability to retrieve mail. So far, I have yet to see anything bad happen. My IMAP test is taking place under Debian GNU/Linux Woody and my POP3 test under FreeBSD 4.7-STABLE. Though any suggestions in what to keep an eye out for in either case? --Ian.

[dovecot] pine/dovecot issues
by David E. Storey 04 Mar '03

04 Mar '03

Folks, I'm running into some issues with pine and dovecot. (dovecot is running mbox for now... plan to switch to maildir soon.) At first I thought it was a funky issue with the way I was using pine to access mailboxes. (I use rsh to invoke imap as pre-authenticated so when I switch to maildirs, I don't have to worry about pine being patched to support it.) But after switching over to using authenticated IMAP over port 143, it still had issues. I'm getting messages like: Junk in start of group Not an Address Junk at end of envelope Unknown Message property Thus far, it seems to only occur in pine. (Squirrelmail and evolution appear to be fine) Is it the client? Is it dovecot? is it easily fixable? It feels like some sort of escaping issue or parsing issue or something. I just don't know enough about IMAP to determine exactly what it is. I'm using dovecot v0.99.8, MAIL=mbox:%h/Mail/:INBOX=%h/.mailbox I've just converted off of wu-imap in hopes of someday migrating to maildirs on that box. (anyone know of a good mbox to maildir conversion tool? I used to have on that worked fine, but I've since found a ton that don't work well for me at all. I have about a gig of email to backup and convert) d!

Actually, I wouldn't mind seeing something like this so I can compress up my old mail and perhaps store them on CD, for example. I tend to archive mailing list traffic by month (which I store in mbox format), so past months tend to not change much, if at all. :) While not an absolute necessity, it'd be nice to have. --Ian.

[dovecot] pop3: last, and auth plain
by Mark E. Mallett 27 Feb '03

27 Feb '03

Hi- A couple of comments regarding the POP3 server (I realize the POP3 server is probably low priority though..) One problem is that the "LAST" command is not supported. Some mail clients end up downloading all messages every time because of this (or so I'm told). The biggest source of these remarks is people using the yahoo webmail front end. I wonder if this could be added? Also, under BSD/OS, the "auth plain" mechanism doesn't work. Perusing the mailing list archives, I see that the symptoms appear just like those that were reported earlier for another BSD system. I'm curious as to whether there has been any progress on that front? Yours, -mm-

[dovecot] 0.99.8 released
by Timo Sirainen 25 Feb '03

25 Feb '03

Hope I didn't forget anything :) v0.99.8 2003-02-25 Timo Sirainen <tss(a)iki.fi> * NOTE: Configuration file has changed a bit: auth_userinfo was replaced by userdb and passdb. *_port were merged into *_listen. Disabling listening in imaps port is now done by changing protocols setting. * Maildir: .customflags location has changed for INBOX. If you have set any custom flags, move Maildir/.INBOX/.customflags into Maildir/.customflags or they will be lost. * mbox: Autodetect /var/mail/%u and /var/spool/mail/%u as INBOXes if they're found and mail_default_env isn't set. * passwd-file: File format changed a bit. If you used realm or mail fields, you'll have to fix the file. See doc/auth.txt for description of the format. + Fully featured POP3 server included. Disabled by default. + Support for LITERAL+, MULTIAPPEND, UNSELECT, IDLE, CHILDREN and LISTEXT extensions. + LDAP authentication support. + Internal API cleanups made Dovecot faster and take less memory + auth_verbose logs now all authentication failures + Support for Solaris 9 sendfilev() + New setting: mail_full_filesystem_access allows clients to access the whole filesystem by simply giving the path before the mailbox name (eg. SELECT ~user/mail/box, LIST "" /tmp/%). While this allows users to share mailboxes, it's not recommended since Dovecot's index files can't be safely shared. + New setting: client_workarounds. + Dynamically loadable authentication modules. Binary package builders should consider using it for at least LDAP. + mbox: Content-Length is saved now to each saved message, so it's now safe to have lines beginning with "From ". + mbox: mail_read_mmaped = no works with it now + Indexes can be kept in memory by adding :INDEX=MEMORY to MAIL environment. There's not much point to do this now though, since the UIDs won't be saved. - COPY now behaves as RFC2060 says: "If the COPY command is unsuccessful for any reason, server implementations MUST restore the destination mailbox to its state before the COPY attempt." - LIST and LSUB rewrite, should fix several bugs in them - maildir_copy_with_hardlinks = yes was broken. - mboxes in subfolders weren't selectable. - STORE didn't accept multiple flags without () around them - PLAIN SASL-authentication was a bit broken. - IMAP dates were parsed a few hours wrong - STATUS command removed \Recent flags from messages - Several bugfixes to SEARCH command, especially related to multiple search conditions - If auth/login process died unexpectedly at startup, the exit status or killing signal wasn't logged. - mbox parsing might have crashed sometimes - mbox: when saving mails, internal headers were allowed in input, sometimes causing problems (eg. duplicate headers) when appending and copying messages - mbox: X-Keywords headers were duplicated - Some small fixes to how messages are saved to Maildir - Next command after STARTTLS was ignored which left the connection stuck sometimes - Dovecot was pretty much broken with FreeBSD

[dovecot] Configuration file format changes

25 Feb '03

After tomorrow's 0.99.8 release I think it's time for a new config file format. It could be made backwards compatibile with the old format, but there would be new tree-like categories. I was thinking something like this: # global settings protocols = imap # "foo.server.org" is just descriptive name # settings inside server { .. } will override global ones. # groups (namespace, login settings, auth settings) aren't replaced # unless same name is used. server foo.server.org { imap_listen = 1.2.3.4 ssl_cert_file = /etc/ssl/certs/foo.cer # default namespace (no name) namespace { type = private mail = mbox:~/mail } # Have to quote so '#' won't be thought out as comment. # I think quoting should work everywhere actually.. namespace "#maildir" { type = private inbox = yes # this namespace contains INBOX mail = Maildir:~/Maildir } # override global auth default auth default { auth_mechanisms = plain digest-md5 auth_realms = foo.server.org auth_userdb = ldap /etc/dovecot-ldap.conf auth_passdb = ldap /etc/dovecot-ldap.conf } } server bar.server.org { imap_listen = 1.2.3.5 ssl_cert_file = /etc/ssl/certs/bar.cer namespace { type = private #mail = #autodetect } # shared mailboxes between users # eg. user/timo.sirainen/some-shared-folder namespace user { type = user mail = /home/%u/mail/shared } } server baz.server.org { imap_listen = 1.2.3.6 ssl_disable = yes # Only Courier-like INBOX namespace namespace INBOX { type = private } } # common namespace between all instances namespace shared { type = shared mail = mbox:/var/lists:INDEX=~/mail/.shared/ } auth default { auth_mechanisms = plain auth_userdb = passwd auth_passdb = pam }

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

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

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

21 Feb '03

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

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

20 Feb '03

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

[dovecot] Re: IMAP folder problem

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

[dovecot] IMAP folder problem
by Kevin Lee 18 Feb '03

18 Feb '03

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

[dovecot] mbox vs maildir debate (was re: subject concerning binc imap, even though my original message never touched on it or maildir)

That was an inadvertent mess-up on my part; I did not see the headers, usually going by the list's reply-to headers which are usually there, but not this time. I only "cross-posted" it because the first time, it went to the wrong list (the dovecot list was a CC line). I then remailed it to the correct list.

Don't confuse POP3 servers in general with mbox > POP3 servers. The root, the source of the evil is the storage format > mbox. <Rest of argument re mbox vs. maildir removed> I am specifcally targeting mbox POP3 servers, of which there are several implementations; Qpopper, GNU POP3 Server, Cucipop, ipop3d to name a few. I am NOT speaking to maildir, nor to Cyrus, nor to SQL-enabled products. Solely to mbox. In fact, I even said that stuff that talks to maildir, in addition to Cyrus, offered the one thing for IMAP you could not get with mbox until Dovecot came along; something resembling robust dealing with multiple clients to the same mbox store. Nor am I particularly insterested in debating the merits of any format over mbox, a format I have stated I -KNOW- has annoying technical limitations and issues. While I would imagine other formats may have advantages over mbox, I continue to use mbox simply because of the sheer amount of stored mail I have accumulated on all my machines for the past seven years. My point is that Dovecot seems to be the most robust IMAP server I have come across at coping with mbox stores, especially if I am trying to access the same mailbox with two different clients, whether intentionally or inadvertnetly. My hope is that Dovecot's POP3 server will prove just as robust at dealing with mailboxes that may also be open by an IMAP client. Whether Dovecot, BINC IMAP, or even Courier IMAP (or whichever POP3 server for that matter) are better for maildir or anything else, I will leave that debate to those who actually use them. In the end, I have made a choice. Not necessarily the best one, but I made the choice with the full understanding of what that choice would entail. However, you never know. I may change my mind later. ;) --Ian.

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

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

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