[Dovecot] FETCH for mailbox INBOX UID 39641 got too little data: 4823 vs 4825
by Mikhail Teterin 04 Jan '08

04 Jan '08

Whenever I try to access an e-mail in the middle (rather than at the end) of the mailbox, my mail-client (KMail) gets an error a message like this is logged in the maillog: IMAP(mi): FETCH for mailbox INBOX UID 39641 got too little data: 4823 vs 4825 IMAP(mi): Disconnected: Disconnected The actual numbers vary, but it is always X vs X+2 The problem started when I upgraded to 1.0.8. Unfortunately, it is still here with 1.0.9. The mailbox in question is the standard Unix mbox (/var/mail/mi in my case). The server runs FreeBSD/amd64. Please, advise. Thanks! -mi

What is correct way to backup dovecot store? Is am I right what is just enough to copy all maildir and my configuration. So in case failure I can just prepare new machine copy config, maildirs and I'm good to go with this.

[Dovecot] dovecot-auth consumes 100% CPU time on Solaris 10
by KOT MATPOCKuH 02 Jan '08

02 Jan '08

Is problem with CPU load solved? I have same problem - dovecot-auth eats one of my cores. I'm using dovecot 1.0.7 on Solaris 10 Sparc. I tried to use auth-bind and standard scheme with separate user for bind and have same result. Problem occupts only with LDAP authentication, on some other systems I use PostgreQSL and MySQL authentication and doesn't have this problem. Using PAM authentication is not possible, because dovecot run in chroot'ed environment and I planing to move it to separate system or zone without ldap client. -- MATPOCKuH

[Dovecot] 1.1b13 build in FreeBSD fails using 'make'; 'gmake' apparently required
by snowcrash 01 Jan '08

01 Jan '08

hi, i'm doing a 1st build of dovecot in a freebsd 62R jail. following instructions at http://wiki.dovecot.org/CompilingSource ./configure make sudo make install after an OK 'configure', @ 'make', i get make make all-recursive Making all in src Making all in lib make: don't know how to make unicodemap.c. Stop *** Error code 1 Stop in /s/usr-local/build/dovecot/dovecot/src. *** Error code 1 Stop in /s/usr-local/build/dovecot/dovecot. *** Error code 1 Stop in /s/usr-local/build/dovecot/dovecot. looking at source, i couldn't figure this out ... on a whim, i tried 'gmake', instead of 'make'. it completes without error. subsequent make check make install are both ok, resulting in ls -al dovecot -rwxr-xr-x 1 root wheel 459786 Dec 30 21:53 dovecot* ./dovecot --version 1.1.beta13 on FreeBSD, apparently, make != gmake ls -al `which make` `which gmake` -r-xr-xr-x 1 root wheel 350904 Dec 29 17:25 /usr/bin/make* -r-xr-xr-x 1 root wheel 199808 Dec 27 06:14 /usr/local/bin/gmake* make --version make: illegal option -- - usage: make [-BPSXeiknqrstv] [-C directory] [-D variable] [-d flags] [-E variable] [-f makefile] [-I directory] [-j max_jobs] [-m directory] [-V variable] [variable=value] [target ...] gmake --version GNU Make 3.81 Copyright (C) 2006 Free Software Foundation, Inc.

This program built for amd64-portbld-freebsd6.2 so, using 'gmake' seems to solve the issue. neither at the link above, nor at, http://wiki.dovecot.org/DovecotServerInstallations/FreeBSD/6.0RELEASE/20Use… is the use of 'gmake'mentioned. i'd ask/suggest that either said mention be added to the wiki (if it's not already there, and i missed it), or, that the build be made to be FreeBSD-make friendly. hth. cheers!

[Dovecot] my.cnf reading support in MySQL backend
by Luca Longinotti 01 Jan '08

01 Jan '08

I hope this ml is the right place to send this... Anyway, I'd very much like for the MySQL backend to call mysql_options, so that it'll read the settings defined in MySQL's my.cnf under the [client] section. This allows to set a whole slew of MySQL specific settings for the MySQL connection, for example to enable the compressed protocol, set charsets, enable SSL client verification, and much more. A patch is attached that implements this. See http://dev.mysql.com/doc/refman/5.0/en/mysql-options.html for more info. -- Best regards, Luca Longinotti aka CHTEKK LongiTEKK Networks Admin: chtekk(a)longitekk.com Gentoo Dev: chtekk(a)gentoo.org SysCP Dev: chtekk(a)syscp.org TILUG Supporter: chtekk(a)tilug.ch

[Dovecot] deliver: keep existing From_ line
by Alexander 'Leo' Bergolth 01 Jan '08

01 Jan '08

Hi! I'm using procmail to filter my email. (I have to use it because of various features that are not supported by sieve.) However, I'd like to deliver mail to my mboxes using dovecots deliver program in order to update index files and speed up mbox access. Using "| $DELIVER -m <mboxname>" in my procmail receipes, everything works fine, except that the envelope sender address is mangled. deliver sets it to MAILER-DAEMON, even though it is already provided in the first line of the mail. I cannot use the "-f <address>" options of deliver, since procmail doesn't provide the envelope-sender address in a variable. (I'd have to extract it from the first line of the mail using a separate receipe, which isn't very efficient.) Is there a way to keep the already existing "From " line? Thanks in advance, --leo -- e-mail ::: Alexander.Bergolth (at) wu-wien.ac.at fax ::: +43-1-31336-906050 location ::: Computer Center | Vienna University of Economics | Austria

[Dovecot] Building path to maildir
by Michel Bulgado 01 Jan '08

01 Jan '08

Hello everyone Happy new year . This is the first time I address to the list I have the following situation and I need help from all you people I have dovecot 0.9-11 and i want to migrate to a superior version like dovecot 1.0 looking forward to implement quotas in my system , and use the function deliver with postfix. My Scenario is as follow Dovecot + LDAP (ADS) + postfix My actual version is : 0.99.11 This is my actual configuration: Protocols = imap pop3 imap_listen = * pop3_listen = * login_dir = /var/run/dovecot-login login = imap login = pop3 default_mail_env = maildir:/var/spool/virtualmail/%d/%n mbox_locks = fcntl auth = dovecot-auth auth_mechanisms = plain auth_default_realm = CASA.CULT.CU auth_userdb = ldap /etc/dovecot-ldap.conf auth_passdb = pam dovecot auth_user = root auth_verbose = yes auth_debug = yes dovecot-ldap.conf hosts = ldap.casa.cult.cu base = ou=CASA,dc=casa,dc=cult,dc=cu dn = cn=unix-conector,cn=Users,dc=casa,dc=cult,dc=cu dnpass = ***** ldap_version = 3 deref = never scope = subtree user_global_uid = 500 user_global_gid = 500 user_attrs = mail,/var/spool/virtualmail/%d/%n,,,, user_filter = (&(objectClass=user)(!(objectClass=computer))(sAMAccountName=%n)) I see many changes in this new version. One of them is : -Renamed default_mail_env to mail_location - many changes in ldap queries With the new version my problem is when to dovecot tries to detect or builds the way where it´s stored the mailbox of my users. In /var/spool/virtualmail/%d/%u , it does not detect the domain when asking to my active directory (w2k) and consequently takes a value of my default realm = casa.cult.cu in this case the default domain where authenticate my users. My configuration in the new version of dovecot: protocols = imap pop3 protocol imap { listen = * } protocol pop3 { listen = * } login_dir = /var/run/dovecot/login login_chroot = yes login_greeting = Dovecot ready. mail_location = maildir:/var/spool/virtualmail/%d/%u mail_debug = yes mbox_read_locks = fcntl mbox_write_locks = fcntl protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota } protocol lda { postmaster_address = postmaster(a)example.com mail_plugins = quota auth_socket_path = /var/run/dovecot/auth-master } auth_executable = /usr/libexec/dovecot/dovecot-auth auth_verbose = yes auth_debug = yes auth default { mechanisms = plain passdb pam { args = dovecot } userdb ldap { args = /etc/dovecot-ldap.conf } userdb prefetch { } user = root socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = virtualmail group = virtualmail } } } dict { } plugin { quota = maildir:storage=10240 } user_attrs = mail,/var/spool/virtualmail/%d/%n,,,, The attribute mail in the old version returns to me user(a)casa.com or user(a)casa.cult.cu this way dovecot can build the way with no problems at all. But in this late version something is happening, it only takes the value %n= user , but not %d = domain . It´s not working. do you have any idea how I can solve this I beg your pardon for my poor English. ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

[Dovecot] Enhanced Kerberos support
by Richard A Nelson 31 Dec '07

31 Dec '07

The recent addition of auth_gssapi_hostname is a welcome addition, but a little more is needed for multi-homed (or multi-domained) sites. SSH recently added this enhancement to address this common need: GSSAPIStrictAcceptorCheck Determines whether to be strict about the identity of the GSSAPI acceptor a client authenticates against. If “yes” then the client must authenticate against the host service on the current hostname. If “no” then the client may authenticate against any service key stored in the machine’s default store. This facility is provided to assist with operation on multi homed machines. The default is “yes”. Note that this option applies only to protocol version 2 GSSAPI connections, and setting it to “no” may only work with recent Kerberos GSSAPI libraries. I've heard that other daemons support multi-names by instead of using gethostname(), obtain the hostname of the interface that the request came in on. Can either approach be looked at for dovecot ?
