[Dovecot] stability?
by K. Clair 28 Feb '07

28 Feb '07

Hi, I'm having trouble figuring this out from any of the documentation or website pages: is dovecot v1.0 considered to be stable, or is it still testing/beta? If the latter, is there any timeline for a "stable" release? Thanks, Kristina

[Dovecot] Migrating to dovecot: non-empty mboxes
by Alexander Shikoff 28 Feb '07

28 Feb '07

Hello, I migrate from cucipop to dovecot. Thus I move users' mailboxes (mbox format) to another location. Some POP3 client (for example Outlook or TheBat!) use flag 'Do not delete messages from server'. After the user's mailbox have been moved to a new location all old messages is retrieved again and user get duplicates. Is there a way to avoid such issue? Thanks a lot! -- Kind Regards, Alexander Shikoff minotaur(a)crete.org.ua

I don't think this was touched from 23 to 24... Also, 24 hasn't hit the FreeBSD ports tree yet, so I'm not certain what would break if I built it manually... --J > On Tue, 27 Feb 2007 14:19:45 -0800 (PST) > chandler.lists(a)chapman.edu wrote: > >> Anyone have a suggestion of what >> to adjust? > > rc24? > > -- > > Brian Morrison > > bdm at fenrir dot org dot uk > > "Arguing with an engineer is like wrestling with a pig in the mud; > after a while you realize you are muddy and the pig is enjoying it." > > GnuPG key ID DE32E5C5 - http://wwwkeys.uk.pgp.net/pgpnet/wwwkeys.html >

[Dovecot] dovecot-auth (1.0rc24) on Solaris seems broken.
by Stephen Usher 28 Feb '07

28 Feb '07

I've trying to get dovecot-auth to talk to exim and have been running debugging on both sides. I've added the line: i_info("auth_client_input: client disconnected: %s", strerror(errno)); just after the "case -1" in the first switch statement in: auth-client-connection.c: auth_client_input() and get this in the logs: dovecot: Feb 27 13:35:09 Info: auth(default): auth_client_input: client disconnected: Illegal seek Now, on the exim end if I don't have the i_info() call in the routine the call to fgets() which exim is using never returns. If I put the i_info() call in there it does and gives an error, e.g. 2007-02-27 13:35:09 dovecot_plain authenticator failed for vanguard.earth.ox.ac.uk [163.1.22.82]: 435 Unable to authenticate at present: authentication socket protocol error Now, the istreams code in dovecot seems rather too obscure for me to debug any further. According to the read(2) man page under Solaris 10, the only version of read which can possibly return ESPIPE is pread(). Any ideas what's going on?

[Dovecot] Capability dropping support patch
by David 27 Feb '07

27 Feb '07

Hi, A week ago I submitted an early patch, please ignore it. The patch attached to this email has been tested and seems to work for me. I have also attached instead of inline to solve problems with spaces/tabs. The patch will, on systems that have libcap support, drop capabilities that Dovecot doesn't need. For example there is no need for CAP_SYS_MODULE, which enables module loading or CAP_SYS_PTRACE/CAP_SYS_ADMIN/etc. If libcap isn't installed then nothing will change, this is a compile-time only enhancement that isn't configurable. Personally I did not find that CAP_SYS_CHROOT was needed in order for me to authenticate and access my mailbox, but I haven't configured anything special with chrooting (yet). I added it because I see chroot() is used in src/lib/restrict-access.c. The patch was generated against 1.0-rc24 and tested with clients imp and Thunderbird. My configuration uses a virtual passdb, requires TLS for AUTH and exports auth-master under a different account. All of this appears to work correctly. I'd appreciate any comments, perhaps this will help safeguard the 1000EUR on non-hardened systems :) David

That's terribly slow (and does for sure not make the maildirsize-file). The only thing I'm unsure of is whether your ldap attribute is called quotaStorage?

[Dovecot] Dovecot rc23 and rc24 freeze after authentication
by Garret Huntress 27 Feb '07

27 Feb '07

I had our production systems running on rc23, however we ran into problems when the server was under heavy load. Eventually, the server would begin to freeze all imap connection after authentication (according to the logs). A user would connect, authentication would succeed, and then the connection would sit until timing out. No error logs were produced. Upgrading to rc24 did not resolve the issue, but reverting to rc22 has. -Garret -- Garret W.

[Dovecot] Certs file

I'm running 1.0rc23 on FreeBSD 6.2-RELEASE, and seeing the following: Starting dovecot. Error: Can't use SSL key file /etc/ssl/private/dovecot.pem: No such file or directory In the config file I have: ssl_cert_file=/usr/local/certs/imapd.pem Looking for dovecot.pem on the config file there's only: % grep dovecot.pem dovecot.conf #ssl_cert_file = /etc/ssl/certs/dovecot.pem #ssl_key_file = /etc/ssl/private/dovecot.pem So the two entries referencing dovecot.pem are commented out. I removed those two lines anyway, just in case, but it didn't make a difference. What am I missing?

Re: [Dovecot] Solaris problem & exim. Please ignore it.
by Stephen Usher 27 Feb '07

27 Feb '07

Please ignore my previous question.. as it turns out it's a bug/feature of fprintf(3C) and sockets under Solaris. Exim was using fprintf to output the AUTH string and for some unknown reason it was hanging, possibly because the input buffer on the file stream wasn't empty or something. After modifying the Exim's dovecot authentication plug-in to use write(2) instead of fprintf(3C) it miraculously worked!

[Dovecot] lstats on all files in Maildir when opening an e-mail.
by Tan Shao Yi 27 Feb '07

27 Feb '07

Hi, I'm running RC19 on a Solaris 10 SPARC box. It seems that whenever I open an e-mail in any folder via IMAP, dovecot appears to scan every other folder in the Maildir. A truss reveals that it is lstat-ing every e-mail in every directory. I'm sorry I am sending only a fragment of the truss, it's really too long... but is this behaviour expected? Cheers, Tan Shao Yi lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170337156.M209211P18431V025055F0I0000DAF0_0.recess1,S=2596", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170337594.M159985P18549V025055F0I0001891B_0.recess1,S=4111", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170338379.M564254P18933V025055F0I000196A3_0.recess1,S=3630", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170344035.M859029P24106V025055F0I000198E4_0.recess1,S=4254", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170344816.M69242P24829V025055F0I000199CB_0.recess1,S=3810", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170347789.M408186P27905V025055F0I00019A8F_0.recess1,S=3922", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170378895.M589722P25748V025055F0I00019279_0.recess1,S=2782", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170380726.M524353P29456V025055F0I0001AEE1_0.recess1,S=3619", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/new/1170381420.M702545P517V025055F0I0001B208_0.recess1,S=3028", 0xFFBFF040) = 0 getdents64(8, 0xFEE72000, 8192) = 0 close(8) = 0 lstat64("/var/qmail/maildirs/AA/AA/test(a)pacific.net.sg/Maildir/.qmail/maildirfolder", 0xFFBFF148) = 0 lstat64("/var/qmail/maildirs/AA/AA/test(a)pacific.net.sg/Maildir/.qmail/cur", 0xFFBFF148) = 0 openat(-3041965, "/var/qmail/maildirs/AA/AA/test(a)pacific.net.sg/Maildir/.qmail/cur", O_RDONLY|O_NDELAY|O_LARGEFILE) = 8 fcntl(8, F_SETFD, 0x00000001) = 0 fstat64(8, 0xFFBFEEE8) = 0 getdents64(8, 0xFEE72000, 8192) = 1088 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/cur/1169092926.M656431P6118V04010002I000023E9_0.recess1,S=4701:2,S", 0xFFBFF040) = 0 lstat64("/var/qmail/maildirs/AA/AA/test@pacific.net.sg/Maildir/.qmail/cur/1168983168.M76366P8906V04010002I000027AB_0.recess1,S=2345:2,S", 0xFFBFF040) = 0

[Dovecot] pid stamp on log entries?

Hi folks. Is there a way to modify the log stamp to include pid as well as time? Preferably for all logging, but at least for imap and pop. I took a look at the mail-login plugin, but that seems to associate operations with uid, still no pid. Am I missing something? Thanks for any info, -Brian U of Minnesota Internet Services

[Dovecot] Bigcrypt password patch
by Philipp Kolmann 26 Feb '07

26 Feb '07

Hi, we are currently in the progress of switching an HPUX mailserver to linux and dovecot. The only issue so far is, that HPUX has bigcrypt for passwords > 8 chars. Bigcrypt uses standard libc crypt for every block of 8 chars. The linux pam modules have a bigcrypt.c file which can be used for dovecot as well to authenticate crypt and bigcrypt passwords. I have used the pam bigcrypt.c code to patch the mycrypt.c dovecot file. Maybe you could add this path (against branch_1_0 cvs). thanks Philipp Kolmann -- If you have problems in Windows: REBOOT If you have problems in Linux: BE ROOT

[Dovecot] Updated SHA256 patch

Hi, This is the updated version of the SHA256 password hashing patch I submitted earlier to this list. I changed it, based on the suggestions by Andrey Panin (AP). Also some other parts have been changed, summary as follows: [sha2.h] - typedef of context dropped for consistency (AP) - removed ifndef SHA2_TYPES part (AP) - removed sha256() prototype [sha2.c] - added lib.h and safe_memset.h includes - added static const to sha256_h0[8] and sha256_k[64] (AP) - replaced memset with safe_memset - used standard types from stdint.h: (AP) - uint32 -> uint32_t - uint8 -> uint8_t - removed strings.h include - removed PACK64 and UNPACK64 (defined but not used) The updated patch can also be found at http://www.malochia.nl/dovecot/sha256.patch Kind regards, Jasper diff -r -u -N --exclude=Makefile.in --exclude=.deps --exclude=Makefile --exclude=CVS dv_bas/src/auth/password-scheme.c src/auth/password-scheme.c --- dv_bas/src/auth/password-scheme.c 2007-02-25 02:13:29.697424750 +0100 +++ src/auth/password-scheme.c 2007-02-23 14:34:23.940550315 +0100 @@ -10,6 +10,7 @@ #include "mycrypt.h" #include "randgen.h" #include "sha1.h" +#include "sha2.h" #include "str.h" #include "password-scheme.h" @@ -153,6 +154,17 @@ return str_c(str); } +static const char *sha256_generate(const char *plaintext, + const char *user __attr_unused__) +{ + unsigned char digest[SHA256_RESULTLEN]; + string_t *str; + sha256_get_digest(plaintext, strlen(plaintext), digest); + str = t_str_new(MAX_BASE64_ENCODED_SIZE(sizeof(digest)+1)); + base64_encode(digest, sizeof(digest), str); + return str_c(str); +} + static const void * password_decode(const char *password, unsigned int result_len) { @@ -196,6 +208,23 @@ return memcmp(sha1_digest, data, SHA1_RESULTLEN) == 0; } +static bool sha256_verify(const char *plaintext, const char *password, + const char *user) +{ + unsigned char sha256_digest[SHA256_RESULTLEN]; + const char *data; + + sha256_get_digest(plaintext, strlen(plaintext), sha256_digest); + + data = password_decode(password, SHA256_RESULTLEN); + if (data == NULL) { + i_error("sha256_verify(%s): Invalid password encoding", user); + return 0; + } + + return memcmp(sha256_digest, data, SHA256_RESULTLEN) == 0; +} + static const char *ssha_generate(const char *plaintext, const char *user __attr_unused__) { @@ -466,6 +495,7 @@ { "MD5-CRYPT", md5_crypt_verify, md5_crypt_generate }, { "SHA", sha1_verify, sha1_generate }, { "SHA1", sha1_verify, sha1_generate }, + { "SHA256", sha256_verify, sha256_generate }, { "SMD5", smd5_verify, smd5_generate }, { "SSHA", ssha_verify, ssha_generate }, { "PLAIN", plain_verify, plain_generate }, diff -r -u -N --exclude=Makefile.in --exclude=.deps --exclude=Makefile --exclude=CVS dv_bas/src/lib/sha2.c src/lib/sha2.c --- dv_bas/src/lib/sha2.c 1970-01-01 01:00:00.000000000 +0100 +++ src/lib/sha2.c 2007-02-25 01:53:03.876815750 +0100 @@ -0,0 +1,226 @@ +/* + * FIPS 180-2 SHA-224/256/384/512 implementation + * Last update: 02/02/2007 + * Issue date: 04/30/2005 + * + * Copyright (C) 2005, 2007 Olivier Gay <olivier.gay(a)a3.epfl.ch> + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.

[Dovecot] Dovecot on Solaris x86?
by Tim Skirvin 24 Feb '07

24 Feb '07

I'm trying to get dovecot working on Solaris x86. I've got it working just fine on RH Desktop 4; and while I have a built, limping version on solx86, it's not actually usable except from other solx86 systems. Basic details: Version 1.0rc23 OS Solaris x86 (64 bit) CPU Opteron Filesystem NFS (but it's not getting that far) The general problem is apparently SSL-related. I can connect properly from another Solaris x86 machine, using either mutt or straight openssl; but when I try mutt from a Solaris or Linux machine, I get the error "SSL failed: I/O error" and it fails, and when I use openssl from a Linux machine, I get something like this: victor ~> stelnet xxxxxxxx.ks.uiuc.edu 993 + openssl s_client -connect xxxxxxxx.ks.uiuc.edu:993 -verify -debug verify depth is 0 CONNECTED(00000003) depth=0 /C=US/ST=Illinois/L=Urbana/O=UIUC/OU=[...] verify error:num=18:self signed certificate verify return:1 depth=0 /C=US/ST=Illinois/L=Urbana/O=UIUC/OU=[...] verify return:1 24748:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:s23_lib.c:226: Annoyingly, the same command run from a Solaris machine connects, even though mutt doesn't. (I'm using 'mutt -f imaps://xxxx/', which I know works elsewhere; and the Linux mutt is the system default one, so I don't suspect that it is the source of the problem.) The logs have been remarkably un-useful: dovecot: Feb 21 09:41:21 Info: imap-login: Disconnected: rip=[...], lip=[...] TLS handshake The software was built in all cases with: ./configure --prefix=/usr/local/encap/dovecot-1.0rc23.1 I've tried with both Sun's native cc and gcc compilers. I have also tried building on SPARC Solaris with the native cc compiler, to the same (negative) effect. (I used to have v0.99.14 running just fine on this SPARC machine, so this worries me... but I only checked it just now as an after-thought.) Any suggestions? - Tim Skirvin (tskirvin(a)ks.uiuc.edu) -- Theoretical and Computational http://www.ks.uiuc.edu/~tskirvin/ Biophysics, Beckman Institute, UIUC Senior Systems Administrator

[Dovecot] Setting up an email server
by Matt Penfold 24 Feb '07

24 Feb '07

I am sure this is a really stupid question but I could do with some advice. I am setting an old PC as an email/file server using Gentoo Linux. So far I have configured getting emails from a couple of a pop3 accounts I have with ISPs/Mail Service providers using getmail and dovecot. I can access those emails from a variety of clients using IMAP without problem. The next stage I want to implement is to have a central location available to the clients of sent emails as well as received emails. It is this part I am a bit confused about. I know I will need some kind of agent to transfer the email from the client to the appropriate ISP/Mail provider but I am overwhelmed by the choice. Sendmail seems a bit OTT for me needs! And how do I ensure that I can see what emails I have send using IMAP ? Thanks in advance Matt Penfold -- No virus found in this outgoing message. Checked by AVG Free Edition.

[Dovecot] Simple patch
by David 23 Feb '07

23 Feb '07

Inline below is a simple patch that drops the root capabilities that aren't needed (inspired by a similar patch against the mpm_itk project!). Possibly it is a little too restrictive, extras can be added to suidcaps, but on platforms that support capabilities this will prevent things such as kernel module loading. Needed on linux is libcap, available in most distros. Note that this patch doesn't require libcap, or add an option, but if it is installed then it will take advantage of it. I don't have any other platforms to test on. The patch compiles fine but I haven't managed to test it yet. My autoconf experience is zero, so I hope that HAVE_LIBCAP is actually getting defined. Comments appreciated, I'll test it thoroughly later when I get some free time (and, if it works, remove the test message!).

[Dovecot] quota warning
by Nicolas Boullis 23 Feb '07

23 Feb '07

Hi, Is there a way with dovecot to warn users who are close to reach their quota? Although I never used it, I think cyrus supports something like that by droping a warning message into the INBOX when delivering a message that brings the total size over a certain percentage. Would it be feasible to implement something like that with an extra plugin or by changing the quota plugin? Cheers, Nicolas

[Dovecot] Final LDAP issues
by Joseba Torre 23 Feb '07

23 Feb '07

Hi all, I'm in my final steps with my testing server using rc23 in a x86 RHEL4 machine. Everything is working quite well, but still are some LDAP related issues I'd like to clarify: - I'm using auth_bind and auth_bind_userdn. So pass_filter isn't used, and pass_attrs are never searched. Is this true or am I missing something? - Is there a choice for the userdb bind/queries to be done using the user supplied dn -the one used for passdb-? I would like to access some non-public attributes, but I've had no luck until now. If I use the same dovecot-ldap.conf for userdb and passdb, i have a single connection to the LDAP server, but once the auth bind is successful, an anonymous bind occurs. If I use two separate files for userdb and passdb, i have two connections to the LDAP server, the second one being always anonimous. For me, the perfect state would be: - bind using the user supplied dn - if successfull, search for pass_attrs, where some user_attrs may be prefetched - unbind - userdb only binds if some needed attrs haven't been already fetched. If so, there's a choice to use the user supplied dn for the bind/search. Is this possible now? Would it be in the future? Thanks in advance. -- Joseba Torre. CIDIR Bizkaia.

[Dovecot] Strange new mail count
by Brian Taber 23 Feb '07

I am having a slight issue with new message count... for some reason, dovecot reports I have some strange number of new messages, even though there are no new messages... If I click on a few of the folders, the new message count seams to correct itself... Any way to solve this?

[Dovecot] out-of-tree plugins and installed header files
by Timo Sirainen 22 Feb '07

22 Feb '07

I added --with-headers configure option now to CVS (not enabled by default). It makes Dovecot install all the useful .h files so that it's possible to compile out-of-tree plugins without having compiled Dovecot sources. I'd hope that binary package builders add a new dovecot-dev package which contains the headers (and $libdir/dovecot- config). I also updated dovecot-sieve so that it compiles against only the header files, except then sievec and sieved binaries aren't compiled (because they require liblib.a).

[Dovecot] 1.0.rc23 released
by Timo Sirainen 22 Feb '07

22 Feb '07

http://dovecot.org/releases/dovecot-1.0.rc23.tar.gz http://dovecot.org/releases/dovecot-1.0.rc23.tar.gz.sig Documentation is probably the only important thing left before v1.0. * deliver doesn't ever exit with Dovecot's internal exit codes anymore. All its internal exit codes are changed to EX_TEMPFAIL. * mbox: X-Delivery-ID header is now dropped when saving mails. * mbox: If pop3_uidl_format=%m, we generate a unique X-Delivery-ID header when saving mails to make sure the UIDL is unique. + PAM: blocking=yes in args uses an alternative way to do PAM checks. Try it if you're having problems with PAM. + userdb passwd: blocking=yes in args makes the userdb lookups be done in auth worker processes. Set it if you're doing remote NSS lookups (eg. nss_ldap problems are fixed by this). + If PAM child process hasn't responded in two minutes, send KILL signal to it (only with blocking=no) - IMAP: APPEND ate all CPU while waiting for more data from the client (broken in rc22) - mbox: Broken X-UID headers assert-crashed sometimes - mbox: When saving a message to an empty mbox file it got an UID which immediately got incremented. - mbox: Fixed some wrong "uid-last unexpectedly lost" errors. - auth cache: In some situations we crashed if passdb had extra_fields. - auth cache: Special extra_fields weren't saved to auth cache. For example allow_nets restrictions were ignored for cached entries. - A lot of initial login processes could cause auth socket errors in log file at startup, if dovecot-auth started slowly. Now the login processes are started only after dovecot-auth has finished initializing itself. - imap/pop3 proxy: Don't crash if the remote server disconnects before we're logged in. - deliver: Don't bother trying to save the mail twice into the default mailbox (eg. if it's over quota). - mmap_disable=yes + non-Linux was really slow with large dovecot.index.cache files - MySQL couldn't be used as a masterdb - Trash plugin was more or less broken - imap/pop3 couldn't load plugins if they chrooted - imap/pop3-login process could crash in some conditions - checkpassword-reply crashed if USER/HOME wasn't set

[Dovecot] Solaris/SSLonly/Lots of Users
by Steven F Siirila 22 Feb '07

22 Feb '07

Anyone running Dovecot on Solaris, requiring only SSL connections, and servicing thousands of simultaneous users? Our past attempts to do so have failed due to dovecot-auth using up all 256 of its file descriptors. I say 256 since we are limited to that by the 32-bit libraries. We are looking at either compiling Dovecot in 64-bit and letting dovecot-auth file descriptors accumulate (not ideal), or providing Timo with access to one of our test servers so he can debug the problem. However, I would like to hear of anyone in the same boat first. Thanks! -- Steven F.

[Dovecot] Dovecot Quota + LDAP
by Venilton Junior 22 Feb '07

22 Feb '07

Hie Folks, I'm having a little problem with quota + ldap. I want to use per user quota settings. So I configured quota on my /etc/dovecot.conf like this site http://wiki.dovecot.org/Quota examples. Here follows my /etc/dovecot.conf: protocols = imap imaps pop3 pop3s ssl_disable = no ssl_cert_file = /usr/share/ssl/certs/cert.pem ssl_key_file = /usr/share/ssl/private/pkey.pem mail_extra_groups = mail valid_chroot_dirs = /var/lib/imap/vmail/domains default_mail_env = maildir:/var/lib/imap/vmail/domains/%d/%n/mail::INDEX=/var/run/dovecot/i ndexes/%n lock_method = dotlock mmap_disable = yes auth_debug = yes auth_debug_passwords = yes first_valid_uid = 202 last_valid_uid = 202 first_valid_gid = 202 last_valid_gid = 202 maildir_copy_with_hardlinks = no login_greeting = Sercomtel Internet ready. disable_plaintext_auth = no protocol imap { mail_plugins = quota imap_quota } protocol lda { postmaster_address = postmaster(a)domain.com mail_plugins = quota } protocol pop3 { pop3_uidl_format = %08Xu%08Xv mail_plugins = quota } auth default_with_listener { mechanisms = plain login userdb ldap { args = /etc/dovecot-ldap.conf } passdb ldap { args = /etc/dovecot-ldap.conf } socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = vmail group = mail } } } plugin { # quota = maildir:/var/lib/imap/vmail/%d/%u/mail:storage=102400 # convert_mail = maildir:/var/lib/imap/vmail/%d/%u/mail #quota = maildir:storage=102400 } And here is my user attributes in my dovecot-ldap.conf: user_attrs = mail,homeDirectory,,,,quotaStorage=quota=dirsize:storage user_filter = (&(objectClass=VirtualMailAccount)(mail=%u)(accountActive=TRUE)(delete=F ALSE)) As you can see above in my dovecot.conf, I made a comment at plugin section to ensure that there's no quota usage for all system. I'd like to have per user quota stored in my ldap base. Here is a value off my quota attribute: quota = 122880 Making tests, the user already have 138 Mb. Does anyone have any idea how to set up quota with ldap and get it working? Tnx for any reply. Best regards, Venilton C. Junior

[Dovecot] Understanding fcntl() error messages
by Dean Manners 22 Feb '07

22 Feb '07

Hey guys, After many trials and tribulations I have now got some fairly stable NFS clients serving dovecot-lda and pop3/imap. Over a 9 hour postal/rabid stress test only saw 5 errors for the 4 servers. Wondering if anyone can shed a bit more light on what they mean exactly. I have tried to find "Resource temporarily unavailable" and "No locks available" in the src to get some understanding - however it appears these messages are from a lower level. With pop3: ------------------ Feb 22 03:36:32 mailget01 dovecot: POP3(test992(a)mailtest06.com): fcntl() failed with file /mnt/mailstore/mailtest06.com/8/test992/dovecot.index.log: Resource temporarily unavailable Feb 22 03:36:32 mailget01 dovecot: POP3(test992(a)mailtest06.com): mail_index_wait_lock_fd() failed with file /mnt/mailstore/mailtest06.com/8/test992/dovecot.index.log: Resource temporarily unavailable Feb 22 04:16:45 mailget01 dovecot: POP3(test445(a)mailtest03.com): fcntl() failed with file /mnt/mailstore/mailtest03.com/4/test445/dovecot.index.log: Resource temporarily unavailable Feb 22 04:16:45 mailget01 dovecot: POP3(test445(a)mailtest03.com): mail_index_wait_lock_fd() failed with file /mnt/mailstore/mailtest03.com/4/test445/dovecot.index.log: Resource temporarily unavailable ------------------ ------------------ Feb 22 13:07:27 mailget01 dovecot: POP3(test999(a)mailtest06.com): fcntl() failed with file /mnt/mailstore/mailtest06.com/8/test999/dovecot.index: Resource temporarily unavailable Feb 22 13:07:27 mailget01 dovecot: POP3(test999(a)mailtest06.com): fcntl() failed with file /mnt/mailstore/mailtest06.com/8/test999/dovecot.index: Resource temporarily unavailable Feb 22 13:07:27 mailget01 dovecot: POP3(test999(a)mailtest06.com): Couldn't open INBOX: Internal error occurred. Refer to server log for more information. [2007-02-22 13:07:27] Feb 22 13:07:27 mailget01 dovecot: POP3(test999(a)mailtest06.com): No INBOX for user top=0/0, retr=0/0, del=0/0, size=0 ------------------ Does this mean that pop3 was waiting for a lock, but timed out ? What are the likely affects of this on a client POPing - session times out and they need to reconnect? The "No INBOX" error is little more odd, the same user had successful login 90 minutes earlier. With deliver: ------------------ Feb 22 01:42:03 mailfilter01 deliver(test680(a)mailtest04.com): fcntl() failed with file /mnt/mailstore/mailtest04.com/10/test680/dovecot.index: No locks available Feb 22 01:42:06 mailfilter01 deliver(test265(a)mailtest03.com): fcntl() failed with file /mnt/mailstore/mailtest03.com/1/test265/dovecot.index: No locks available Feb 22 03:25:42 mailfilter02 deliver(test454(a)mailtest03.com): fcntl() failed with file /mnt/mailstore/mailtest03.com/2/test454/dovecot.index: No locks available Feb 22 03:25:45 mailfilter02 deliver(test397(a)mailtest03.com): fcntl() failed with file /mnt/mailstore/mailtest03.com/7/test397/dovecot.index: No locks available ------------------ I assume this means deliver tried to obtain a lock on the index file (probably many times) but failed. Are the likely affects that the message still gets saved to the maildir but the index doesn't get updated? Regards __________________________________________ Dean Manners

[Dovecot] critical performance problem
by Rene Luria 22 Feb '07

22 Feb '07

I have been using dovecot 1.0alpha4 + deliver/sieve in production for a few accounts (400'000). After testing 1.0.rc22 I decided to upgrade one of the imap servers... And... what a mess ! The server just gets unusable. I don't know why but with new release, it just overloads the system with I/O. It turns that with 1.0.rc22 I get 15Mo/s read on disk average, without any reason. What did really change ? How come a system (with a few thousand accounts) works perfectly and then with 1.0.rc22 gets unusable with a load approaching 300 ? If you have any ideas...

[Dovecot] 1.0.rc23 tomorrow
by Timo Sirainen 22 Feb '07

22 Feb '07

http://dovecot.org/nightly/dovecot-latest.tar.gz Would be nice to get some testing before the actual release. I've now finally gone through all the "TODO" mails in this list and my INBOX and fixed pretty much every problem I know of. There are still some mbox bugs, but I can't really get them fixed unless someone figures out how to reproduce them (http://wiki.dovecot.org/MboxProblems) I think documentation is the last thing that should be done before v1.0. I'm happy enough with the code as it is now, unless some new bugs again appear. The notable changes since rc22: * deliver doesn't ever exit with Dovecot's internal exit codes anymore. All its internal exit codes are changed to EX_TEMPFAIL. + PAM: blocking=yes in args uses an alternative way to do PAM checks. Try it if you're having problems with PAM. + userdb passwd: blocking=yes in args makes the userdb lookups be done in auth worker processes. Set it if you're doing remote NSS lookups (eg. nss_ldap problems are fixed by this). + If PAM child process hasn't responded in two minutes, send KILL signal to it (only with blocking=no) - IMAP: APPEND ate all CPU while waiting for more data from the client (broken in rc22) - mbox: When saving a message to an empty mbox file it got one UID which immediately was incremented. - mbox: Fixed some wrong "uid-last unexpectedly lost" errors. - auth cache: In some situations we crashed if passdb had extra_fields. - auth cache: Special extra_fields weren't saved to auth cache. For example allow_nets restrictions were ignored for cached entries. - A lot of initial login processes could cause auth socket errors in log file at startup, if dovecot-auth started slowly. Now the login processes are started only after dovecot-auth has finished initializing itself. - imap/pop3 proxy: Don't crash if the remote server disconnects before we're logged in. - deliver: Don't bother trying to save the mail twice into the default mailbox (eg. if it's over quota). - mmap_disable=yes + non-Linux was really slow with large dovecot.index.cache files - MySQL couldn't be used as a masterdb - Trash plugin was more or less broken - imap/pop3 couldn't load plugins if they chrooted - imap/pop3-login process could crash in some conditions - checkpassword-reply crashed if USER/HOME wasn't set

[Dovecot] --log-error and the mysterious "not starting" problem
by Marshal Newrock 22 Feb '07

22 Feb '07

I've finally upgraded to 1.0.rc21. If I run "dovecot --log-error", then dovecot fails to start. The following appears in the log: Feb 5 10:54:00 taurus1 dovecot: Dovecot v1.0.rc21 starting up Feb 5 10:54:00 taurus1 dovecot: This is Dovecot's error log Without --log-error, it will start up fine from command-line. Dovecot still fails to start, as near as I can tell, in the specific condition that it is being started from a non-interactive shell and there is a mail_plugin set in "protocol imap". mail plugins set for pop or lda do not cause this problem. The failure to start appears in only two instances that I can see: on boot, or by a monitoring script if dovecot crashes, or, since I haven't seen dovecot die, when I manually stop it to see if the monitoring program will restart it. With the above problem, if the init script has --log-error when I try to make the monitoring program restart dovecot, then nothing still gets logged. -- Marshal Newrock, Ideal Solution LLC http://www.idealso.com

[Dovecot] False "new mail" warning from Thunderbird, using RC23
by Stephen Warren 21 Feb '07

21 Feb '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I am continually getting false "New Mail" warning from Thunderbird. I'm running Thunderbird 1.5.0.9 on Windows, and it's talking to two different Dovecot 1.0.RC23 servers (one home server, one work server). This was happening in older Dovecot versions too, so it's not new in RC23. Very often, Thunderbird will pop up the "new mail" notification window, and put a "new mail" icon in the Windows icon bar. However, when I view the main Thunderbird window, there will be no folders with new mail. Simply changing the currently selected folder in Thunderbird will clear the tray icon. Sometimes the notification window will say something small like "7 new messages", but right now, it's showing huge numbers like "587 new messages", which could be the total message count in one of my folders... Sometimes restarting Thunderbird will stop this happening for a short while. Is this a Thunderbird bug? Am I the only one seeing this? Does it have to do with having two separate IMAP servers configured? Perhaps it's because Thunderbird is configured to cache 5 connections to the server (although I think that's the default?) Should I delete all my accounts in Thunderbird, delete the (Thunderbird) cache files etc. on disk, and re-create it all? I do notice that whenever Thunderbird starts, it displays a whole load of folders that don't exist (e.g. got renamed/deleted) and/or multiple copies (e.g. Sent, Sent-1, Sent-2), which disappear very quickly. Is this related? -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFF2+eJhk3bo0lNTrURAh9uAKCWYrcNByF+wE2e1FPvL6x8N48/uACgtwxR 07fYmnaG9P/JCBOkKscCZIA= =XWXG -----END PGP SIGNATURE-----

[Dovecot] auth_user setting?
by Joseba Torre 21 Feb '07

21 Feb '07

Hi all, I've installed rc23 in a new testing machine, and i've had some permission problems related to dovecot-master.conf. As I have my master passwords in that file, I don't want it to be world readable. dovecot -n shows that auth_user is nobody, so setting the permissions to nobody.whatever 640 solves the problem. Anyway, I've tried to change the auth_user setting with no effect. Is it configurable? Aaaaaaaaaagur. -- Joseba Torre. CIDIR Bizkaia.

[Dovecot] Possible Bug in quota-fs.c
by Martin Konopka 20 Feb '07

20 Feb '07

Hi, I'm using filesystem quotas with dovecot 1.0rc22 on my Linux 2.4.27 box. The quota limit gets correctly reported in kilobytes to the client but the amount of used space is reported in megabytes. In quota-fs.c I noticed that only the currently used space is divided by 1024: Line 241: *value_r = dqblk.dqb_curblocks / 1024; *limit_r = dqblk.dqb_bsoftlimit; After removing /1024 everything works fine. regards, Martin

convert_mail = mbox:%h/mail Convert plugin. If set, specifies the source storage path which is converted to destination storage (mail_location) when the user logs in. The existing mail directory is renamed to <dir>-converted. I'm not entirely clear on what this does. If someone can clarify for me, I'll update the Wiki.

[Dovecot] Reading mail for Virtual and Real LDAP Users
by Aaron Luchko 20 Feb '07

20 Feb '07

I'm trying to setup a system with ldap+postfix+dovecot. Everyone who gets an email is stored in LDAP, some of these users also have a local unix account, regardless I want all users to be dealt with as virtual users. All the mail is stored by postfix in /var/spool/mail in Maildir format with permissions 600 vmail:vmail. Everything works fine when dovecot tries to read the mail of a completely virtual user, the problem is when dovecot tries to read mail for a user who has an account on the machine, dovecot finds the user's local account, then it tries to read the mail as that user. Even if first_valid_{u,g}id is low enough to allow login the user still doesn't have sufficient permissions to read the mail. I can't figure out why this is happening and was hoping someone could help me out. thanks, Aaron /etc/dovecot-ldap.conf: hosts = server.example.com base = dc=example,dc=com dn = cn=Directory Manager dnpass = password uris = ldap://127.0.0.1 user_attrs = mail user_filter = uid=%u user_global_uid = 5001 user_global_gid = 5001 pass_filter = uid=%u /etc/dovecot.conf: mail_location = maildir:/var/spool/mail/%u/ protocols = imap pop3 mail_log_prefix = "%Us(%u):%i:%h " first_valid_uid = 5001 first_valid_gid = 5001 protocol imap { } protocol pop3 { } protocol lda { postmaster_address = postmaster(a)example.com } auth_verbose = yes auth_debug = yes auth default { mechanisms = plain passdb pam { } userdb passwd { } userdb ldap { args = /etc/dovecot-ldap.conf } passdb ldap { args = /etc/dovecot-ldap.conf } user = root } dict { } plugin { }

[Dovecot] NTLM oddities
by Cassidy B. Larson 20 Feb '07

20 Feb '07

Started implementing the MasterUser changes to my config files so I can finally offer SPA for pop3/imap. Things are working fine with the MasterUser (horray!), however one of my guys started using SPA with Outlook Express and started getting another users mailbox. Turns out to be related to NTLM. His Outlook express is configured for the username of 'johnsmith'. However, you'll see the NTLM took the username from his XP machine login, it appears, which is just "John". However, what is really weird, is the "failed" on the "client out" line, but then the proxy went ahead and proxied to the storage server. Here's some output from debuggage: dovecot: Feb 19 16:15:56 Info: auth(mail.infowest.com): client in: AUTH 1 NTLM service=POP3 lip=204.17.177.60 rip=209.33.215.142 resp= dovecot: Feb 19 16:15:56 Info: auth(mail.infowest.com): client out: CONT 1 dovecot: Feb 19 16:15:56 Info: auth-worker(mail.infowest.com): sql(John, 209.33.215.142): query: SELECT a.clearpasswd AS password, v.storeIP AS host, CONCAT(IF('John' LIKE '%(a)%.%',CONCAT(LCASE('John'),''),CONCAT(LCASE('John'),'@',p.host)),'*masteruser') AS destuser, 'Y' AS nologin, 'Y' AS nodelay, 'Y' AS proxy, 'masterpass' AS pass FROM iwmailsystem.virtmailbox AS v INNER JOIN iwmailsystem.popserversAS p ON ( p.storeIP = '204.17.177.60') INNER JOIN authenticate.users AS a ON (a.userID= IF('John' LIKE '%(a)%.%',CONCAT(LCASE('John'),''),CONCAT(LCASE('John'),'@', p.host))) WHERE v.userID = IF('John' LIKE '%(a)%.%',CONCAT(LCASE('John'),''),CONCAT(LCASE('John'),'@',p.host)) AND v.client_active=1; dovecot: Feb 19 16:15:56 Info: auth(mail.infowest.com): password(John, 209.33.215.142): Credentials: 8447128CC04AD05D1CD15F0C2F17F136 dovecot: Feb 19 16:15:57 Info: auth(mail.infowest.com): client out: FAIL 1 user=John host=204.17.177.76 destuser= john(a)host.com*masteruser nologin proxy pass=masterpass dovecot: Feb 19 16:15:57 Info: pop3-login: proxy(John): started proxying to 204.17.177.76:110: user=<John>, method=NTLM, rip=209.33.215.142, lip= 204.17.177.60 Questions: 1) So is it possible to use OE for SPA authentication without it sending the "XP username", but the actual account username OE is configured for ? 2) Why, when it "FAIL"ed did it still proxy? This seems bad :) Thanks, Cassidy

[Dovecot] relocating indexes.
by Rob Shepherd 20 Feb '07

20 Feb '07

Dear Dovecot users, I'd like to relocate indexes from NFS to local storage. I plan to replace... default_mail_env = maildir:~/.maildir with mail_location = maildir:~/.maildir:INDEX=/usr/local/var/dovecot/index/%u However, to minimise disruption, by avoiding dovecot rebuilding indexes for many user's large and numerous folders, I'd like to copy the existing indexes to the new location. Here is a list of _my_ indexes (in and under ~/.maildir) ./.Drafts/dovecot-uidlist ./.Drafts/dovecot.index ./.Drafts/dovecot.index.cache ./.Drafts/dovecot.index.log ./.OpenLDAP/dovecot-keywords ./.OpenLDAP/dovecot-uidlist ./.OpenLDAP/dovecot.index ./.OpenLDAP/dovecot.index.cache ./.OpenLDAP/dovecot.index.log ./.OpenLDAP/dovecot.index.log.2 ./.Sent/dovecot-keywords ./.Sent/dovecot-uidlist ./.Sent/dovecot.index ./.Sent/dovecot.index.cache ./.Sent/dovecot.index.log ./.Trash/dovecot-keywords ./.Trash/dovecot-uidlist ./.Trash/dovecot.index ./.Trash/dovecot.index.cache ./.Trash/dovecot.index.log ./.mailscanner/dovecot-keywords ./.mailscanner/dovecot-uidlist ./.mailscanner/dovecot.index ./.mailscanner/dovecot.index.cache ./.mailscanner/dovecot.index.log ./.mailscanner/dovecot.index.log.2 ./.nagios/dovecot-keywords ./.nagios/dovecot-uidlist ./.nagios/dovecot.index ./.nagios/dovecot.index.cache ./.nagios/dovecot.index.log ./.samba/dovecot-keywords ./.samba/dovecot-uidlist ./.samba/dovecot.index ./.samba/dovecot.index.cache ./.samba/dovecot.index.log ./.samba/dovecot.index.log.2 ./.sw-announce/dovecot.index ./.sw-announce/dovecot.index.cache ./.sw-announce/dovecot.index.log ./dovecot-keywords ./dovecot-uidlist ./dovecot.index ./dovecot.index.cache ./dovecot.index.log ./dovecot.index.log.2 Would I be correct in copying these to /usr/local/var/dovecot/index/rob/ (_my_ new index loc) whilst preserving the structure of the folders etc. Thanks Rob -- Rob

[Dovecot] startup script under FreeBSD 6.2 / dovecot-1.0rc22
by Alexis Susset 20 Feb '07

20 Feb '07

Hi all, I recently installed Dovecot rc22 from the FreeBSD ports and I have some problem with the dovecot startup: - If I start dovecot manually, it works fine, it starts and I get messages in /var/log/maillog - If I reboot the machine, that's where the problem appears, dovecot doesn't seem to start and I get nothing, no errors in /var/log/maillog Any idea if this is a known problem and how to fix it ? Thanks in advance, Regards, -- Alexis

[Dovecot] Run fetchmail after login?
by Brett B. 20 Feb '07

20 Feb '07

Hello all, I was wondering if it is possible to run fetchmail after a user logs into dovecot? So far I have tried to make a small script that contains the command for fetchmail. Then I told the dovecot mail_executable to look at that script. However this ends up leaving the server hanging and does not seem to work. Thanks

[Dovecot] Dovecot losing .mailboxlist files
by Lauri Jesmin 20 Feb '07

20 Feb '07

Hello! I am running a site that has two servers, 10 000 users in both, Solaris 9 and home directories with mbox mailboxes shared with NFS. Indexes are kept separately in both server, on local disks, both servers are serving imap (from NFS mboxes). We are trying to convert from uw-imap to dovecot. Servers are currently running on their limits and now i have mysterious problems with .mailboxlist file: i patched dovecot to use .mailboxlist file instead of .subscriptions, but sometimes the .mailboxlist file disappears on some users. Instead there are appearing .nfsXXXXXX files, where XXXXXX is combination of numbers and capital letters. Also some users have problems with subscribing to folders, others do not have this problem. It seems to be that users who do not have .mailboxlist have also problems with subscribing to folders. Dovecot is version 1.0rc22. I have not discovered error messages in logs. -- Lauri Jesmin <lauri.jesmin(a)ut.ee> Tartu Ülikool

[Dovecot] Weird Issues with latest nightly (pre-rc23)
by Cassidy B. Larson 19 Feb '07

19 Feb '07

Just updated one of my proxy boxes to the latest nightly (20070217), restarted the dovecot process and got a bit of errors showing up for each pop3/imap connection. Feb 19 11:14:00 marbella dovecot: pop3-login: Login: user=<user1(a)host.com>, method=PLAIN, rip=209.33.217.218, lip=204.17.177.60 Feb 19 11:14:00 marbella dovecot: POP3(user1(a)host.com): Set pop3_uidl_format in config file Feb 19 11:14:00 marbella dovecot: child 33684 (pop3) returned error 89 Feb 19 11:14:04 marbella dovecot: imap-login: Login: user=<user2(a)host.com>, method=PLAIN, rip=204.17.177.50, lip=204.17.177.60 Feb 19 11:14:04 marbella dovecot: IMAP(user2(a)host.com): mbox: Can't create root mail directory /dev/null/mail: Not a directory Feb 19 11:14:04 marbella dovecot: IMAP(user2(a)host.com): MAIL environment missing and autodetection failed (home /dev/null) Feb 19 11:14:04 marbella dovecot: child 33753 (imap) returned error 89 On the pop3 errors above. Why should I have a pop3_uidl_format in the config file for the proxy? This was working fine on rc19. I do have a pop3_uidl_format on my storage boxes. Same with the imap section. It should just proxy over (and is on rc19), the proxy shouldnt have to know about the mail directory. Am I the only one seeing this? Or have I missed a config change that is required? thanks, Cassidy

Hi all, New SUSE 10.2 install, Sendmail, dovecot 1.0.rc14-7 SUSE rpm. Was using PAM for authentication. Worked like a champ since Feb 7th. No changes to system. Yesterday authentication failed. I can't even authenticate locally with "telnet localhost" options to test pop3 or imap. It appears that my pam authentication has somehow gotten changed. Can anyone direct me to some PAM debugging help? Thanks, Marion

[Dovecot] LDAP auth load? (looking for advice)
by Troy Engel 19 Feb '07

19 Feb '07

One of the changes my beta testers are testing is switching from NIS to LDAP for login/auth/homedir lookups; all is working perfectly, Dovecot + PAM/nss_ldap is A-OK. No issues here, we've been using LDAP lookups on other servers for years. I'm wondering about load, specifically if when I switch the entire company over, will the new authentication load stress my LDAP server to the point of breaking. A) Does anyone here have some numbers or experience in this switch that could lend some real-world advice? We're talking maybe... 50 people with large (numerically, not gig-age) mailboxes, and ThunderBird seems to open 4-5 connections per client based on the logs. B) Would anyone advise that I run a slapd slave directly on the main Dovecot server to alleviate load? Is this overkill and I shouldn't worry about it? Mainly what has me concerned is that on the Dovecot machine, I'm getting a number of entries in the messages that look like: dovecot-auth: nss_ldap: reconnecting to LDAP server... dovecot-auth: nss_ldap: reconnected to LDAP server after 1 attempt(s) No failures ever, it all just works. But still this tickles my brain that maybe it'll need more robustness come production time. Thanks for your feedback, -te -- Troy Engel | Systems Engineer Fluid Inc. | http://www.fluid.com

[Dovecot] repeat downloads of message headers in 1.0rc19
by Brian G. Peterson 19 Feb '07

19 Feb '07

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

[Dovecot] wrong dovecot GID while upgrading
by Zbigniew Szalbot 18 Feb '07

18 Feb '07

Hello, I tried to upgrade dovecot from 1.0.rc7 to rc22 but I got this error at the end of the upgrade process: Dovecot has reserved the groupname 'dovecot' and gid '143': ERROR: groupname 'dovecot' already in use by gid '1003' Please resolve these issues and try again: Either remove the conflicting group or if you wish to continue using a legacy gr oup override DOVECOT_GID. *** Error code 1 Stop in /usr/ports/mail/dovecot. So I went to /usr/ports/mail/dovecot and edited the Makefile to change the GID into: DOVECOT_UID?= 1003 DOVECOT_GID?= 1003 SCRIPT_ENV+= DOVECOT_UID=${DOVECOT_UID} \ DOVECOT_GID=${DOVECOT_GID} I saved the makefile and ran portupgrade again but I got stopped by exactly the same error. I'd appreciate suggestions how to resolve this. Thank you! -- Zbigniew Szalbot

[Dovecot] Reproducible duplicate messages bug with Mail.app+Dovecot
by Andrew Moran 18 Feb '07

18 Feb '07

Hey guys, I am not sure if this is a Mail.app bug or a dovecot bug. I can reproduce it 100% of the time using dovecot and Mail.app. I cannot reproduce it with other imap clients, which at first made me think it was Mail.app, but then I tried Mail.app with other imap servers and couldn't reproduce it either, so it's definitely the combination of the two. So I thought I'd try you guys first before submitting a bug to Apple. The problem: If I move multiple messages (set "A") from one imap folder to another, then delete those messages, and then move another set into that same folder (set "B"), then all the messages in set B show up as duplicates until I relaunch Mail.app. My configuration: Server: Dovecot 1.0rc22 using Maildir on FreeBSD 6.1 Client: Mail.app 2.1 on OS X 10.4.8 Steps to reproduce: (these steps involve trashing messages, so it's best to test this on email you are going to toss anyway) 1) Create a new imap folder (let's say "bar") 2) Drag more than one message (let's say 3 or 4) from existing imap folder "foo" to new folder "bar". 3) Click on new folder "bar" and see messages in there. 4) Select messages and delete them (Delete key). Messages are gone as expected. 5) Go back to original folder "foo" and drag a few more messages into new folder "bar" 6) Click on bar. 7) You will notice that all the second set of messages show up twice. Relaunching Mail.app at this point makes the problem disappear. I'm guessing this has something to do with the deleted messages from Set A being purged until the close of imap connection. Any help narrowing this down would be appreciated. Thank you, --Andy

[Dovecot] Problem moving emails with attachments or HTML links
by J. Wren Hunt 18 Feb '07

18 Feb '07

I recently switched from UW-IMAP to Dovecot (1.0.rc15 on Ubuntu) and am experiencing a weird problem that I haven't been able to figure out yet: If I try to move a message from one IMAP folder to another, all works fine if the message is plain text. However, *sometimes* the message will not be transferred if it contains either an attachment and/or an HTML link (operation times-out). Not all the time, but just enough to be annoying. I've looked through the logs and for settings in the .conf file and can't find anything obvious that I've overlooked. Can anyone help me with any parameters that might be causing this type of problem? Thanks so much! Wren Hunt Cambridge, MA

By default, Dovecot sets the database users table to "users" but I would like to change it to "mailboxes". this is because I don't want to change all my configiuration files already setup, only for dovecot. is this possible? best regards, xtura Fedora Core 6 Dovecot 1.0 rc22

[Dovecot] Dovecot "open files" (again?)
by falz 17 Feb '07

17 Feb '07

I'm a new dovecot user, just began using it last week. I switched from courier because my research showed that Dovecot did indexes, and allows me to store them anywhere I chose. I did this, and it fixed some severe disk IO issues that my server had. (25k horde only webmail install using imap proxy). I'm using quotas, and by default had it set to 'dirsize'. my postfix is already creating 'maildirsize' files, so I opted to change dovecot to use this instead. However, when I do, I run into the "too many open files" issue that's been reported many times on the list. I've seen a lot of mention of too many open files, but I haven't seen it related to the quota type used. It's possible that simply my using 'dirsize' as the quota type slows things down enough to not have the issue? I don't really know. Anyhow. I doubled my max open files in FreeBSD's /boot/loader.conf to: kern.maxfiles="24656", but to no avail. When I have it set to maildirsize, the open files on the system grows uncontrollably. Under normal use, it's somewhere below 5k: sysctl -a | grep openfiles kern.openfiles: 4415 I looked into the patch mentioned here: - http://www.dovecot.org/list/dovecot/2006-November/017536.html - http://dovecot.org/list/dovecot-cvs/2006-November/006776.html Those patches already appear to be in rc15, which I'm already running (Via FreeBSD's ports). I also applied the patch mentioned here awhile back: - http://www.dovecot.org/list/dovecot/2005-June/007647.html and rebuilt, but it didn't help out either. There are also freebsd specific notes on forcing a limit on dovecot itsself using login.conf, but that wouldnt really fix anything, it would just cause dovecot to not interfere with other running daemons. - http://www.mail-archive.com/ports@openbsd.org/msg08646.html Any thoughts? TSS, you mention a few times in these notes that you're unable to reproduce this. Perhaps try with the maildir as quota? More details about my setup: - FreeBSD 4.8 (yea, I know) - Imapproxy (http://www.imapproxy.org/) - Postfix to create maildir++ maildirsize folders - MySQL backend The work of this is spread out between several servers, dovecot is running on the server that's the final SMTP delivery location, and has local disks with the maildirs. --falz

[Dovecot] Problem/workaround with X-Keywords and Apple's Mail.app
by Joey Coleman 17 Feb '07

17 Feb '07

Hello, I've just switched from UW-IMAP to Dovecot, and for the most part, things are good. However, I encountered the problem with the X-Keywords header not being written back into individual messages in an mbox file (originally described in [1], and Timo gave a clue as to maybe why in [2]). What was happening for me is that Apple's Mail.app would flag a message as spam, which happily sets a couple keywords in the message, but those weren't being written back (at least, I didn't see them in the file on the server). The "DO NOT DELETE..." message had a perfectly fine X-IMAP header, and up until I switched things were working great. The user visible symptom of this happened every time new spam arrived in my Junk folder [3] --- the new spam would arrive, be flagged as spam by Mail.app, and the earlier pieces of mail would promptly be unflagged! Anyway, Timo's clue in [2] prompted me to turn off both mbox_lazy_writes and mbox_dirty_syncs (the latter just on the off- chance... it's a low-volume server, so I can deal with the inefficiency). Lo and behold, Mail.app started acting sane again *and* the X-Keywords header appeared immediately. Oddly, during all of this, the Status and X-UID keywords would appear in the messages just fine; no clue as to why those and not X- Keywords. Version details are: - Dovecot 1.0rc13 [4] - FreeBSD 5.3-RELEASE - Apple Mail.app 2.1 (752/752.2) cheers, --joey [1] http://dovecot.org/list/dovecot/2006-March/011872.html [2] http://dovecot.org/list/dovecot/2006-June/014126.html [3] And it felt really strange while troubleshooting this as I found myself *hoping* for another piece of spam to arrive. Bleh. [4] Yes, two versions behind current, but in my defense, I did check the announcements and they didn't seem to mention the problem.

[Dovecot] again... cross compiling
by Martin Höfling 17 Feb '07

> Create a cache file with the right values, or call configure with those > values set in the environment. OK, i ran configure with -C one time without cross compiler env set, to obtain the variables another time with -C to use the config.cache . I could not find anything related to the check whether size_t is signed. I found a variable which i set that way: ignored_signed_size=${ignore_signed_size=1} What's wrong with that? Cheers Martin P.S.: Is there a way to obtain all variables in an easy way, or to obtain the variable that has to be set by hand? -- Frag' nicht - Du könntest eine Antwort erhalten.

Since deliberate choice is required to go in and set the maillist option, this is no different than if I configure my MUA to set the reply-to header on messages I send to the list. So the way it has been implemented for this list is not a problem at all. If people feel the need to reply to me off list, I feel that should be a deliberate choice on their part. -- Kenny Dail <kend(a)amigo.net>

[Dovecot] filtering out LIST cruft?
by Dan Price 17 Feb '07

17 Feb '07

In planning our migration, I've noticed that lots of users have bits of lint in their ~/mail and/or ~/Mail. For example-- for an mbox called "blah" we may see: blah blah.msf (from Thunderbird) .blah.summary (from... I'm not sure, dtmail maybe) .blah_SIMS_index0003 (from our old IMAP server). When the user goes to "subscribe" they are often overloaded with too many items to choose from-- because all of these files are selectable in the UI-- LIST happily returns them. Is there a way to get dovecot to skip over these, by regex? Could it optionally "taste" files to see if they look like mboxes? I looked at the wiki and the source but didn't find anything. In the absence of this feature, I wonder how other sites have handled this? Obviously I can do some cleanup during migration, but I find that those pesky msf files like to come back. -dp -- Daniel Price - Solaris Kernel Engineering - dp(a)eng.sun.com - blogs.sun.com/dp

[Dovecot] severe performance problem (mail cache related?)
by Dan Price 17 Feb '07

17 Feb '07

Hi all, we're having a bad day with email :) I have a user who was complaining of poor performance today when opening mailboxes. Total time to open the box was about 1 minute. Upon truss'ing the imap process during an open, I saw the trace quoted below at the end of the email. As you can see, for each "FETCH" line of response, we were seeing dovecot do a ton of work-- mmaping anon, lots of munmaps(), etc. -- mmap() and munmap() are not free. The stack trace of at least one of the munmaps is captured below, as well-- deep inside of the mail caching code. Then, I moved aside the user's .imap directory, assuming that forcing dovecot to rebuild its indices and caches could help-- and sure enough the user reported that mailbox open times had dropped to 18 seconds. I truss'd that open, briefly, and it was just a ton of preads at high speed. So I don't know why this user was fine for a week, then suddenly hit this. This is a grave concern if I'm going to roll this out from 15 test users to 250 production users. Thanks for your help.

by Robert Schetterer 16 Feb '07

16 Feb '07

Hi @ll, with dovecot latest following http://wiki.dovecot.org/DovecotLDAPostfixAdminMySQL i have defined plugin { quota = maildir acl = vfile:/etc/dovecot/acls trash = /etc/dovecot/dovecot-trash.conf } Example dovecot-trash.conf file 1 Spam 2 Trash 3 Sent from wiki The Trash plugin. When saving a message would make user go over quota, this plugin automatically deletes the oldest mails from configured mailboxes until the message can be saved within quota limits. this dont work at my setup where quota is coming out of sql is there any trick to solve this? or did i missunderstand something -- Mit freundlichen Gruessen Best Regards Robert Schetterer https://www.schetterer.org Munich/Bavaria/Germany

Re: [Dovecot] repeat downloads of message headers in 1.0rc19
by Jim Garrison 16 Feb '07

16 Feb '07

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

[Dovecot] Proxy with MasterUser + Authentication issues
by Cassidy B. Larson 16 Feb '07

16 Feb '07

Per Timo's direction, I decided to give the MasterUser a try in connecting my proxy to my destination server. This might allow for the use of 'secure password' for my clients that like to check that box by default. A couple of problems I'm running into running RC15: #1: My Proxy's SQL password_query line: password_query = SELECT a.clearpasswd AS password, v.storeIP AS host, CONCAT(v.userID,'*someuser') AS destuser, 'Y' AS nologin, 'Y' AS nodelay, 'Y' AS proxy, 'somepass' AS pass FROM iwmailsystem.virtmailbox AS v NATURAL JOIN authenticate.users AS a WHERE v.userID = '%u' and v.imap_active = 1 I'm wanting to authenticate the user on the proxy before I send it off via the MasterUser to the destination server. However, I show this in the logs: Info: auth(default): client in: AUTH 1 PLAIN service=IMAP lip= x.y.z.a rip=a.b.c.d resp=AGJ1dGNoQGluZm93ZXN0LmNvbQBzZWNyZXQ= Info: auth-worker(default): sql(user(a)host.com,a.b.c.d): query: SELECT a.clearpass wd AS password, v.storeIP AS host, CONCAT(v.userID,'*someuser') AS destuser, 'Y' AS nologin, 'Y' AS nodelay, 'Y' AS p roxy, 'somepass' AS pass FROM iwmailsystem.virtmailbox AS v NATURAL JOIN authenticate.users AS a WHERE v.userID = 'user(a)host.com' and v.imap_active = 1 Error: auth(default): file auth-request.c: line 207 (auth_request_save_cache): assertion failed: (extra_fields == NULL || (strstr(extra_fields, "\tpass=") == NULL && strncmp(extra_fields, "pass=", 5) != 0)) Error: child 54122 (auth) killed with signal 6 The Wiki showed I should return a 'pass' column. However, that's choking the query up in auth-request.c. Could it be the "\tpass" from auth-request.c? If I change user(a)host.com's password to 'someass' and remove the 'pass' column from the password_query, it authenticates, and proxy's over just fine. Am I doing something wrong? I want to authenticate the user locally on the proxy and pass off the 'master password' to the proxy, but using 'pass' doesnt work. 'password' column does. Doesnt help me though for my situation :) Problem #2: I'm wanting to put the masteruser/pass in the database for quick retrieval and updating. So I setup dovecot.conf as: passdb sql { # Path for SQL configuration file, see doc/dovecot-sql.conf for example args = /usr/local/etc/dovecot-sql.conf master=yes #pass=yes } passdb passwd { } and dovecot-sql.conf with: password_query = SELECT '%u' AS user, 'master-password' AS password Trying to connect locally with a "telnet localhost 143" via: 1 login user(a)host.com*someuser "somepass" Give me this in the detail log file: Info: auth(default): client in: AUTH 1 PLAIN service=IMAP lip= a.b.c.d rip=w.x.y.z resp=AGJ1dGNoQGluZm93ZXN0LmNvbSphZG1pbkBpbmZvd2VzdC5jb20AbWFzdGVyLXBhc3N3b3Jk Error: auth-worker(default): BUG: PASSV had invalid passdb ID Warning: Killed with signal 15 I am able to successfully authenticate with the master user/pass if I store it in a passdb file. However, I'd prefer to have it in the database for obvious reasons. Any help to the above would be appreciated. thanks, Cassidy

[Dovecot] Dovecot proxy question (hostname instead of ip)
by Wouter de Jong 16 Feb '07

16 Feb '07

Hello, We are planning to use the Proxy feature of Dovecot, but fail to implement it currently the way we would like to. Reason is that proxy insists to have an IP-address as host : Feb 15 15:43:24 proxy-test.widexs.nl dovecot: pop3-login: proxy(username): mspool01-test.widexs.nl is not a valid IP When I changed the query to force the IP-address of the above server, it works. Would it be possible to make this work, but more important ... Are there any reasons NOT to make this work ? :)) Kind regards, Wouter. -- WideXS http://www.widexs.nl Wouter de Jong System-Administrator Tel +31 (0)23 5698070 Fax +31 (0)23 5698099 Bijlmermeerstraat 62, 2131 HG HOOFDDORP, NL

[Dovecot] domain truncated
by Nemanja Miletic 16 Feb '07

16 Feb '07

Hi all, I have a problem with domain information being truncated from username during ldap search, so it can not be used in mail_location. This happens when user part of the username %n is used in pass_filter in passdb ldap search. When I use %u all username information remains and mailbox can be located. Here is my configuration. In dovecot.conf I have two locations one for system and one for virtual users: ... mail_location = maildir:/var/spool/mail/%n mail_location = maildir:/var/spool/mail/vdom/%d/%n ... Also two configurations for passdb: ... passdb ldap { args = /etc/dovecot-ldap.conf } passdb ldap { args = /etc/dovecot-ldap-virt.conf } ... Here info is searched in ldap: /etc/dovecot-ldap-virt.conf ... base = dc=%d,ou=Virtual Domains,dc=eunet,dc=yu pass_filter = (&(objectClass=posixAccount)(uid=%n)) ... And the line in log file stating that maildir can not be located: mkdir(/var/spool/mail/vdom//cone/cur) failed: Permission denied Is this a bug or I am doing something wrong. Thank You, Nemanja

I'm not sure if this is related or not, but we set mmap_disable=yes last week and since then have seen what appears to be an occasional infinite loops.

There is no error logged in the dovecot log when this occurs, and it only stops by "kill -9" on the process... # top -c PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME CPU COMMAND 7832 virtual 25 0 580 496 376 R 71.5 0.0 70:59 0 imap [user(a)example.com 192.168.1.14] # lsof -p 7832 COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME imap 7832 virtual cwd DIR 147,0 600 2372995 /data1/mail/ex/example.com/us/user imap 7832 virtual rtd DIR 3,3 4096 2 / imap 7832 virtual txt REG 3,3 412996 789553 /usr/libexec/dovecot/imap imap 7832 virtual mem REG 3,3 33856 771355 /usr/lib/dovecot/lib10_quota_plugin.so imap 7832 virtual mem REG 3,3 7720 771364 /usr/lib/dovecot/imap/lib11_imap_quota_plugin.so imap 7832 virtual mem REG 3,3 106912 278626 /lib/ld-2.3.2.so imap 7832 virtual mem REG 3,3 14868 278653 /lib/libdl-2.3.2.so imap 7832 virtual mem REG 3,3 1571824 278633 /lib/tls/libc-2.3.2.so imap 7832 virtual 0u IPv4 -1140164370 TCP vip.mail17a.r4.iad.mlsrvr.com:imap->director2.r2.iad.emailsrvr.com:56195 (ESTABLISHED) imap 7832 virtual 1u IPv4 -1140164370 TCP vip.mail17a.r4.iad.mlsrvr.com:imap->director2.r2.iad.emailsrvr.com:56195 (ESTABLISHED) imap 7832 virtual 2w FIFO 0,5 3154802927 pipe imap 7832 virtual 3r CHR 1,9 599160 /dev/urandom imap 7832 virtual 4r FIFO 0,5 3154802928 pipe imap 7832 virtual 5w FIFO 0,5 3154802928 pipe imap 7832 virtual 6r FIFO 0,5 3154802929 pipe imap 7832 virtual 7w FIFO 0,5 3154802929 pipe imap 7832 virtual 8u REG 22,1 11112 6602923 /var/index/data1/mail/ex/example.com/us/user/.Elementos enviados/dovecot.index imap 7832 virtual 9u REG 22,1 50824 6602903 /var/index/data1/mail/ex/example.com/us/user/.Elementos enviados/dovecot.index.log imap 7832 virtual 10u REG 147,0 3074 6346008 /data1/mail/ex/example.com/us/user/maildirsize imap 7832 virtual 11w REG 147,0 905650 7062984 /data1/mail/ex/example.com/us/user/.Elementos enviados/tmp/1171483586.P7832Q0M770594.mail17a.r4.iad.mlsrvr.com # strace -p 7832 read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable) read(0, 0x96ca1f0, 3992) = -1 EAGAIN (Resource temporarily unavailable)

[Dovecot] Wiki to doc/ in tarball
by Timo Sirainen 16 Feb '07

16 Feb '07

So I finally started building a script that does it. Anyone interested in helping with it so that it produces readable output? First step is getting raw wiki pages. I'll do this directly by getting them from the filesystem. You can get them from here: http://dovecot.org/tmp/wikipages.tar.gz Next there's http://dovecot.org/tmp/wiki2txt.pl which is my horrible Perl script that kind of works now to produce almost readable text files. Its current output is in http://dovecot.org/tmp/wikitxt.tar.gz One thing I'm wondering about is how to make the directory layout work. For example there is "UserDatabase" and "UserDatabase/Static" pages. Currently I'm placing the latter into "_UserDatabase/Static" but I don't think that's the best solution. I was thinking about adding some "include" and "exclude" lists. If a page is in excluce list it's skipped. If it's in neither list it prints a warning but still includes it. So this makes it easy to find out the new pages and figure out if they should be included in the documentation.

[Dovecot] Son't have IMAPS

Hi, I've installed dovecot and i'm pretty sure it has SSL support built in. But i don't have IMAPS. I get all sort of errors. Thunderbird tells: "The connection was refused". If i disable imaps, imap works just fine. If i enable it, none of them work. The certificates in /etc/ssl/certs and /etc/ssl/private are the same ? Any help would be appreciated.

[Dovecot] Is it 1.0 yet?
by Marc Perkel 15 Feb '07

15 Feb '07

OK - my last main bug was fixed a few releases ago. I know that there's no end to getting things right but there comes a point when you need to call it done. No one trusts a 1.0 to be perfect but Dovecot is already better that most 2.0 versions of other software. I vote (as if my vote counted) to call it done, declare victory, and move on to 1.01, 1.02 etc. No one is going to trus it till it gets to 1.02 so I say lets bless it and move on.

[Dovecot] 1.0.rc22 released
by Timo Sirainen 15 Feb '07

15 Feb '07

http://dovecot.org/releases/dovecot-1.0.rc22.tar.gz http://dovecot.org/releases/dovecot-1.0.rc22.tar.gz.sig Found another bad bug in rc19 changes. Wonder why my imaptest catched the bug only in CVS HEAD but not in branch_1_0 even though both had it. Anyway, now the imaptest runs nicely for both, and I'm again optimistic that the bug count is low enough for v1.0 to be released soon :) BTW. My previous benchmarks which showed how mmap_disable=yes and fsync_disable=yes give huge performance benefits are pretty XFS-specific. I did some quick tests with ext3 and the differences were quite small with it. I'll probably do another proper run of tests later. + pop3: Commit the transaction even if client didn't QUIT so cached data gets saved. - Fixed another indexing bug in rc19 and later which caused transactions to be skipped in some situations, causing all kinds of problems. - mail_log_max_lines_per_sec was a bit broken and caused crashes with dovecot -a - BSD filesystem quota was counted wrong. Patch by Manuel Bouyer - LIST: If namespace has a prefix and inbox=no, don't list prefix.inbox if it happens to exist when listing for %.
