[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. A backport to woody is also available from http://www.braincells.com/open/ -- Jaldhar H. Vyas <jaldhar(a)debian.org> La Salle Debain - http://www.braincells.com/debian/

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

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.

I don't know either. My idea is to get rid of PAM for that's although fantastic on the paper is a Linux thing that I can't even compile here.

[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.

[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?

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

16 Jun '03

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

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

14 Jun '03

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

Hi- In a mbox environment: 1 login username password 1 OK Logged in. 2 create "slar" 2 NO Internal error [2003-06-11 15:44:56] 3 create "/slar" 3 NO Invalid mailbox name: /slar 4 create "Mail/slar" 4 OK Create completed. 5 create "./slar" 5 OK Create completed. 6 create "blar" 6 NO Internal error [2003-06-11 15:46:54] 7 logout * BYE Logging out 7 OK Logout completed. i.e. I get "internal error" if there is no path component in the folder name. Is this a problem? I would guess that "internal error" is always a problem :-) mm

[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
by Spectron International, Inc. 14 Jun '03

14 Jun '03

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] Help setting up SSL?

Hi, Sorry to bother, I don't know if this mailing list is the right place to look for help setting up dovecot.. Anyway I've got standard IMAP working fine, and I used mkcert.sh after editing the openssl config, and it seemed to work properly (I had to change some directories, I am using the FreeBSD 5.1-CURRENT port).. Anyway, when I try to connect using Outlook, here is what the log shows: (without the exact ip address shown, dont hax0r my windows machine!) imap-login: Jun 10 13:13:14 Warning: SSL_accept() failed: error:1408F455:SSL routines:SSL3_GET_RECORD:decryption failed or bad record mac [12.106.77.x] imap-login: Jun 10 13:13:14 Warning: SSL_accept() syscall failed: EOF [12.106.77.x] imap-login: Jun 10 13:13:14 Panic: key not found from hash dovecot: Jun 10 13:13:14 Error: child 32935 (login) killed with signal 6 imap-login: Jun 10 13:13:14 Warning: SSL_accept() failed: error:1408F455:SSL routines:SSL3_GET_RECORD:decryption failed or bad record mac [12.106.77.x] imap-login: Jun 10 13:13:14 Warning: SSL_accept() syscall failed: EOF [12.106.77.x] imap-login: Jun 10 13:13:14 Panic: key not found from hash dovecot: Jun 10 13:13:14 Error: child 32937 (login) killed with signal 6 so it says "decryption failed or bad record mac".. Does this mean I don't have my .pem files set up correctly? Or is there a problem with the OpenSSL libraries? I'd sure appreciate any help you could give me. Thanks, Mike

[Dovecot] the most serius problems [part 1]
by Farkas Levente 30 May '03

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!"

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.
