[Dovecot] alpha4 and zlib-plugin?
by Jeff A. Earickson 27 Oct '05

27 Oct '05

Hi, I saw the zlib-plugin reference in the alpha4 ChangeLog notes are searched the list for info about it. The only reference I found was from Timo back in March 2005. Questions: 1) Is this going to become a standard part of version 1.0? 2) Any plans or ability to make it read/write to a gzipped mailbox, or is this possible? Or will it always be read-only? 3) How does a mailbox get gzipped? From within dovecot somehow, or only by external action? Jeff Earickson Colby College

Hello! > Do you have reason to believe that the clients are issuing a delete > command and that the mail is incorrectly being left on the server OR do > they have a 'keep mail on server' option checked? I'm sure thet they have 'keep mail on server' unchecked. When uw-ipop3d was used, mail was correctly deleted. Best regards Krzysztof

[Dovecot] Two "pre-migration" questions
by Alan Mead 26 Oct '05

26 Oct '05

I have read the migration docs. They seem to relate to migrating from one imap product to dovecot on the same server. I'm interested in migrating my Maildir-formatted email from one server to another. 1. Can I tar my ~/mail directory on serverX.com, untar it on a different physical serverY.com (initially with a different domain name), and still see my mail when I access imap.serverY.com <http://imap.serverY.com> (dovecot's running on serverY.com .. but let me know if there are any tricks that I need to make this work). 2. If I maintain large mailboxes and check my mail frequently, how does the dovecot server load compare to something like apache or Samba? I ask because I have a vanity domain that I mostly use for email and I want to ensure that I can migrate my precious emails to a new service provider. And the provider that I'm considering offers low-cost virtual dedicated servers but meters usage (including RAM and CPU). One of the reasons I have question #1 is that the server name seems to be part of the email file names... amead:/home/amead> ls mail/cur | head -2 2022292282.22297_0.vulcan.rootr.net:2,S 2022312282.3225_0.vulcan.rootr.net:2,S (rootr.net <http://rootr.net> is my current provider, not my vanity domain; vulcan is the name of their mailserver) I don't know what effect this will have, if any? Thanks! -Alan

[Dovecot] choosing syslog facility?
by Dominik Werder 25 Oct '05

25 Oct '05

Hello! How can I log dovecots messages into a separate file? Is it possible to set a custom syslog facility name somehow? I can't set the log file in dovecot because dovecot does not automatically rotate the logs like syslog does.. thank you! Dominik

[Dovecot] dual auth with real users and virtual users

[Dovecot] Case of %n (feauture request)
by Alexander Shikoff 24 Oct '05

24 Oct '05

Hello, I'm using dovecot not for a long time but I've newer seen most powerful and handy POP3/IMAP server. Thank Timo for dovecot; thank community for help! I would like to notice that %n is case-sensitive: it always stores user part of login without case conversions. As a result there are some inconveniences with virtual user organization, for example: password_query = SELECT `password` FROM `users` WHERE login = '%u' user_query = SELECT "mbox:/var/mail/virtual/%d/%n:INBOX=/var/mail/virtual/%d/%n:INDEX=MEMORY" AS `mail`, 101 AS `uid`, 101 AS `gid` FROM users WHERE login = '%u' In this example authentication works perfectly but user can not access it's mailbox because all mailbox names are lower-case. I think it would be more handy to make %d, %n and %u aliases lower-case and introduce three new aliases %D %N %U which store values without case conversions. But I'm not enough skilled in C to write a patch... and now I'm waiting for comments on this and answer from the developer. Thanks in advance, Alexander. -- Kind Regards, Alexander Shikoff minotaur(a)crete.org.ua

[Dovecot] dovecot + postfix + freebsd help
by glemme 23 Oct '05

23 Oct '05

Hi. I'm currently setting up dovecot to work with my server. My inboxes from postfix are stored in /usr/var/spool/mail/ and then the username, so for me that would be / usr/var/spool/mail/viktor my homedirectory is /usr/home/glemme/homes/viktor/ so from what i can understand. My settings should be: default_mail_env = mbox:%h/Mail:INBOX:/usr/var/spool/mail/%u But guess what, I am probably wrong. my mailapp tells me my inbox is empty and my log claims this: dovecot: Oct 22 16:39:35 Info: imap(viktor: Effective uid=1015, gid=1004 dovecot: Oct 22 16:39:35 Info: imap(viktor: mbox: data=/usr/home/ glemme/homes/viktor/Mail:INBOX:/usr/var/spool/mail/viktor dovecot: Oct 22 16:39:35 Info: imap(viktor): mbox: INBOX defaulted to /usr/home/glemme/homes/viktor/Mail/inbox dovecot: Oct 22 16:39:35 Info: imap(viktor): mbox: root=/usr/home/ glemme/homes/viktor/Mail, index=/usr/home/glemme/homes/viktor/Mail, inbox=/usr/home/glemme/homes/viktor/Mail/inbox Why is it defaulting from the right INBOX to the wrong one?

[Dovecot] 1.0alpha2: how to reject specific users?
by Jeff A. Earickson 21 Oct '05

21 Oct '05

Hi, In Qualcomm's qpopper, you can specify a list of users to reject at authentication, even if they are otherwise valid, by putting them in a file (/etc/pop.nonauth). I use this to occasionally ban users who bang on the system needlessly until they Get a Clue. I looked thru the wiki.dovecot.org/Authentication pages and didn't see anything like this feature. Does it exist in 1.0? BTW, running 1.0alpha2 in production since Sunday night, working great. Zero core dumps, only minor chatter about "Corrupted index cache file" in the syslog, no problems.

[Dovecot] imaps on alternate ports
by Andrew D. Clark 21 Oct '05

21 Oct '05

I'm trying to test out dovecot 1.0 alpha 3 prior to an upgrade from dovecot-0.99.14, but I cannot get imaps listening on anything other than 993. I've tried putting listen = *:2023 in the global section or in the imap { } section. No luck. What is the proper format for a config that only runs imaps and only listens on a particular port? -- Andrew Clark Campus Network Programmer University of California, Santa Barbara andrew.clark(a)ucsb.edu (805) 893-5311

[Dovecot] alpha4: flock change
by Jeff A. Earickson 20 Oct '05

20 Oct '05

Timo, The comments in dovecot-example.conf regarding lock_method for Solaris users needs to note your change. Your changelog says: - Default lock_method changed to flock instead of the old fcntl. Solaris users will need to set it back to fcntl. This makes sure that Dovecot's indexes aren't accidentally used with NFS. But there is no warning about this in the file for Solaris users. There should be; it will bite somebody later. Jeff Earickson Colby College

[Dovecot] [PATCH] Support for GSSAPI SASL Mechanism
by Jelmer Vernooij 20 Oct '05

20 Oct '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, Attached is a patch against current CVS that adds support for the GSSAPI SASL mechanism. It was written from scratch, after reading the patch from Colin Walters against a much older version of dovecot. Other then support for the 'GSSAPI' mechanism, it contains the following changes: - - Added 'auth_krb5_keytab' option for overriding default keytab location. The gssapi library already uses the environment variable KRB5_KTNAME to allow overriding of the keytab location, so I didn't have to make any changes on the login process side. - - Added 'need_passdb' member to mech_module and allow having no passdb's specified if no mechanisms need them (only useful for GSSAPI at the moment) Cheers, Jelmer - -- Jelmer Vernooij <jelmer(a)samba.org> -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (GNU/Linux) iD8DBQFDVgaEPa9Uoh7vUnYRAscGAJ9Fa4E5ze5IX3UeAfjwg7kzj5tgtQCcDva7 O5VTeOeJ7zpmHullxQN6q1Y= =60w7 -----END PGP SIGNATURE----- Index: configure.in =================================================================== RCS file: /home/cvs/dovecot/configure.in,v retrieving revision 1.214 diff -u -r1.214 configure.in --- configure.in 23 Sep 2005 13:28:40 -0000 1.214 +++ configure.in 19 Oct 2005 08:25:31 -0000 @@ -118,6 +118,15 @@ fi, want_bsdauth=yes) +AC_ARG_WITH(gssapi, +[ --with-gssapi Build with GSSAPI authentication support (default)], + if test x$withval = xno; then + want_gssapi=no + else + want_gssapi_yes + fi, + want_gssapi=yes) + AC_ARG_WITH(ldap, [ --with-ldap Build with LDAP support], if test x$withval = xno; then @@ -1192,6 +1201,17 @@ ]) fi +have_gssapi=no +if test $want_gssapi = yes; then + AC_CHECK_PROG(KRB5CONFIG, krb5-config, YES, NO) + if test $KRB5CONFIG = YES; then + AUTH_LIBS="$AUTH_LIBS `krb5-config --libs gssapi`" + AUTH_CFLAGS="$AUTH_CFLAGS `krb5-config --cflags gssapi`" + AC_DEFINE(MECH_GSSAPI,, Build with GSSAPI support) + have_gssapi=yes + fi +fi + if test $want_ldap = yes; then AC_CHECK_LIB(ldap, ldap_init, [ AC_CHECK_HEADER(ldap.h, [ @@ -1486,5 +1506,6 @@ echo "Building with IPv6 support .......... : $want_ipv6" echo "Building with pop3 server ........... : $want_pop3d" echo "Building with mail delivery agent .. : $want_deliver" +echo "Building with GSSAPI support ........ : $have_gssapi" echo "Building with user database modules . :$userdb" echo "Building with password lookup modules :$passdb" Index: dovecot-example.conf =================================================================== RCS file: /home/cvs/dovecot/dovecot-example.conf,v retrieving revision 1.155 diff -u -r1.155 dovecot-example.conf --- dovecot-example.conf 16 Oct 2005 14:59:12 -0000 1.155 +++ dovecot-example.conf 19 Oct 2005 08:25:31 -0000 @@ -568,9 +568,13 @@ # automatically created and destroyed as needed. #auth_worker_max_count = 30 +# Kerberos keytab to use for the GSSAPI mechanism.

[Dovecot] "passdb" userdb
by Thomas Hummel 20 Oct '05

Hello Timo, How exactly would translate the "passdb" userdb example which is in the Wiki for SQL auth with LDAP auth, both in dovecot.conf and dovecot-ldap.conf ? -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] Large IMAP operations tend to timeout and cause problems?
by Alen Salamun 20 Oct '05

20 Oct '05

Hello all! I have moved from Courier-IMAP to Dovecot some month ago. It is quite stable on everyday use (1.0alpha4) but it has constant problems with large IMAP/SSL operations. We use Maildir format. For example if I select 400 messages, mark them deleted and use "purge command" in Thunderbird (to actually delete them) TB starts to do something and runs and runs and runs....Then I get script timed out errror and I have to restart TB. That never happened with Courier-Imap. Same thing happens for example moving 1000msgs to another folder or something like that. Another thing is still that from time to time dovecot indexes get corrupted and users can't access some folders. Then I have to delete dovecot* in that Maildir folder and it works again. Any thoughts on that please? BR, Alen

[Dovecot] Alpha1..2.. and 3 with Tru64
by Alfonso Sparano 20 Oct '05

20 Oct '05

Hi all, I've found a little problem to compile dovecot on a tru64 os v5.1. The problem is the lack of the "inttypes.h" into the included header in the project. Without this include the make process will fail because it can't find the uint32 type. So is sufficient to add the line '#include <inttypes.h>' in the src/lib/lib.h of the tgz distribution package.

[Dovecot] passwd and virtual users
by Erick Perez 20 Oct '05

20 Oct '05

Hi, im runnign dovecot 0.99.14 with standard pop3 auth and a default .conf file. Everything works fine. But now I need to enable virtual users for several domains in the same server while keeping the local auth. my postfix is already working for the virtual domains. What do i need to modify to enable /etc/passwd auth (already done) and virtual domains auth? in the virtual part, i have no idea. Thanks, -- ------------------------------------------- Erick Perez

[Dovecot] Failed authentication to a mysql database (bug or PEBKAC?)
by jigen 19 Oct '05

19 Oct '05

Hi, dovecot has a little crazy behaviour connecting to a mysql db: if you specify "127.0.0.1" as host instead of "localhost" it seems to work, also with a password. BUT, if you assign host=localhost without a password, it works too (as Ger Visschers says).... One more question: how I can specify more different mysql-db conteining different users? I try in the following way: passdb sql { args = /etc/dovecot/dovecot-mysql_django.conf args = /etc/dovecot/dovecot-mysql_debord.conf } and also: passdb sql { args = /etc/dovecot/dovecot-mysql_debord.conf } passdb sql { args = /etc/dovecot/dovecot-mysql_django.conf } but it always seems to remember only the last args value and it tries to connect only one db... bye jigen -- jigen <jigen(a)metalabs.org> MeTA~LAbS

[Dovecot] Message not found errors
by Andrew Hutchings 19 Oct '05

19 Oct '05

Hi, I'm getting a very small amount of users getting message not found errors while downloading mail via POP. By the time they inform me and I switch on rawloging for them it works again. Any ideas where this is going wrong? Or at least a way I can diagnose it? It seems to have been happening since Alpha 1. Currently using pre-release of Alpha4.
