[Dovecot] file system permissions
by Anil 20 Jan '08

20 Jan '08

I am using Maildir and virtual domains. I have the following definitions in the dovecot.conf: mail_uid = 10000 mail_gid = 10000 mail_location = maildir:/var/mail/apps/%d/%n/Maildir ... Userdb database is LDAP based. Some users in LDAP might have a uid/gid defined. If thats the case, I want dovecot to use those uid/gid. If the user in LDAP does not have a uid/gid attribute, it'll fall back to using mail_uid/mail_gid as defined above. (atleast thats what I am hoping to do...) I set the permissions of /var/mail/apps, /var/mail/apps/%d directories 1777. I also see the following error message when a message is received to one of the users: Jan 13 18:33:33 vds5 deliver(admin(a)domain.com): [ID 702911 mail.error] stat(/var/mail/apps/domain.com/admin/Maildir/tmp) failed: Permission denied The permissions of this tmp directory are: drwx------ 2 vmail vmail 2 Jan 13 18:31 tmp Why is deliver having problems writing to that? At this point, what uid is deliver running as? Thanks!

[Dovecot] maildirsize quota does not referred after migration from courier
by Tim Chen 20 Jan '08

20 Jan '08

Dear All, We would like to migrate our existing courier to dovecot. After reading document on website and doing some tests, here are some issues we met. 1. According the the wiki, it seems to imply that once migrating from courier to dovecot, pop3 users may "lost/forget" their download "index/ history" which cause them to download again old mails that are kept on server side. If this is true, it would seriously annoy our users since they always keep old mails on server so that they can access them through webmail interface. Is there anyway to avoid this kind of situation? 2. Currently, we use only /etc/passwd to store our user information. Postfix is our MTA and maildrop is MDA. Quota settings were wriiten in the maildirsize file reside under Maildir directory at everyone's home. The command we use to set user quota: /usr/local/bin/maildirmake -q 315000000S Maildir After installing a test environment using dovecot v1.1.beta13, we found that it does not read the quota settings from the maildirsize file, instead, it only rely on the system wide settings. This could be a problem since we have different quota settings for different groups of users. Is this a bug of v1.1? Or should I use v1.0 instead? Will v1.1 fix this bug in the future? Best regards, Tim Chen

Re: [Dovecot] Time just moved backwards error even with ntpd

That's why I suggested to use ntpdate to force the correct time to be set before ntpd even starts and the ntp init script returns. Admittedly, this won't work if you have no network connectivity during boot up, but if you have, this paticular problem is most likely solved. ntpdate optionally can be given a timeout value and indicates success or failure via its return code so that a calling script might initiate appropriate measures.

[Dovecot] Time just moved backwards error even with ntpd
by Luigi Rosa 19 Jan '08

19 Jan '08

Scenario: server PC abruptly switched off due to power cable problems (an UPS cannot solve this issue), so during shutdown Linux was not able to resinchronize the system clock. After a few hours the server come back on, Linux booted and the services (ntpd, dovecot and many others) started But the system clock was 45 minutes ahead, so: Jan 19 11:13:39 gw ntpd[2112]: synchronized to LOCAL(0), stratum 10 Jan 19 11:13:39 gw ntpd[2112]: kernel time sync disabled 0041 Jan 19 11:14:43 gw ntpd[2112]: synchronized to 62.48.35.100, stratum 2 Jan 19 10:31:55 gw ntpd[2112]: time reset -3600.221385 s Jan 19 10:31:55 gw ntpd[2112]: kernel time sync enabled 0001 Jan 19 10:31:55 gw dovecot: Time just moved backwards by 3600 seconds. This might cause a lot of problems, so I'll just kill myself now. http://wiki.dovecot.org/TimeMovedBackwards Ciao, luigi -- / +--[Luigi Rosa]-- \ Spoon boy: Do not try and bend the spoon.

by libero1 19 Jan '08

19 Jan '08

Ciao everbody, I have a simple question for who has a few experience with dovecot. I want to share a mailbox with some users, I configure dovecot and now in my thinderbird I can see the public namespace. The problem is that I cann't see the "inbox" of the mailbox, in other words when a mail arrive in this mailbox I can not see it, but only what is in other folders. Why? Is it normal? What can I do to let my users to see new messages? Thanks for you help. Bye

Hi FETCHing a largish (~30K) zlib compressed maildir message causes an assertion failure on an attempt to grow the stream buffer to smaller than its current size. I believe the attached patch fixes this.

[Dovecot] Out of the box: Thank you!
by Patrick Ben Koetter 17 Jan '08

17 Jan '08

I've just enabled IMAP quota support on a LDAP userbase in about an hour. In this hour I read the Dovecot documentation on quota support, extended the customers LDAP schema, added a "mailQuota"-attribute and a value to all users, enabled the plugin in dovecot.conf, added the attribute query in dovecot-ldap.conf, reloaded the system and tested the functionality and ... everything worked out of the box. Thank you Timo! p@rick -- state of mind Agentur für Kommunikation, Design und Softwareentwicklung Patrick Koetter Tel: 089 45227227 Echinger Strasse 3 Fax: 089 45227226 85386 Eching Web: http://www.state-of-mind.de Amtsgericht München Partnerschaftsregister PR 563

[Dovecot] Need help to install dovecot on solaris 10 with openldap libs
by Dovecot Jami 17 Jan '08

17 Jan '08

Hi, I install dovecot with ldap support at Solaris 10 (x86). I know that solaris LDAP is broken and so I install openldap. OpenLDAP shared libraries are at /usr/local/lib and /usr/local/include. While installing dovecot, I did the followings: I execute this before run "./configure --with-ldap" LDFLAGS="-L/usr/local/BerkeleyDB.4.2/lib -R/usr/local/BerkeleyDB.4.2/lib -L/usr/local/lib -R/usr/local/lib" but dovecot is using the Solaris default LDAP lib files. I also run LDFLAGS="-R/usr/local/lib" and LDFLAGS="-L/usr/local/BerkeleyDB.4.2/lib -L/usr/local/lib /usr/local/lib/libldap-2.3.so.0 " But dovecot is still using solaris ldap libs. ldd /usr/local/libexec/dovecot/dovecot-auth libcrypt_i.so.1 => /usr/lib/libcrypt_i.so.1 libpam.so.1 => /lib/libpam.so.1 libldap.so.5 => /usr/lib/libldap.so.5 libsocket.so.1 => /lib/libsocket.so.1 libnsl.so.1 => /lib/libnsl.so.1 librt.so.1 => /lib/librt.so.1 libsendfile.so.1 => /lib/libsendfile.so.1 libc.so.1 => /lib/libc.so.1 libgen.so.1 => /lib/libgen.so.1 libcmd.so.1 => /lib/libcmd.so.1 libsasl.so.1 => /usr/lib/libsasl.so.1 libmd5.so.1 => /lib/libmd5.so.1 libnspr4.so => /usr/lib/mps/libnspr4.so libplc4.so => /usr/lib/mps/libplc4.so libnss3.so => /usr/lib/mps/libnss3.so libssl3.so => /usr/lib/mps/libssl3.so libmp.so.2 => /lib/libmp.so.2 libscf.so.1 => /lib/libscf.so.1 libaio.so.1 => /lib/libaio.so.1 libpthread.so.1 => /lib/libpthread.so.1 libthread.so.1 => /lib/libthread.so.1 libdl.so.1 => /lib/libdl.so.1 libsoftokn3.so => /usr/lib/mps/libsoftokn3.so libplds4.so => /usr/lib/mps/libplds4.so libdoor.so.1 => /lib/libdoor.so.1 libuutil.so.1 => /lib/libuutil.so.1 libbsm.so.1 => /lib/libbsm.so.1 libsecdb.so.1 => /lib/libsecdb.so.1 libtsol.so.2 => /lib/libtsol.so.2 libm.so.2 => /lib/libm.so.2 Please help me to solve this problem.
