Hi, I would like to know if the pop3-login process would be create more than one while a user connection is established. http://wiki.dovecot.org/RunningDovecot ------------------------------------ imap-login and pop3-login processes handle new IMAP and POP3 connections until user has logged in. ------------------------------------ I'm sorry to ask you this kind of question...

[Dovecot] Expire plugin: wrong mailbox separators in database?
by Andreas Ntaflos 16 Oct '09

16 Oct '09

Hi all, I'm experimenting with the expire plugin and seem have run into a small problem. I am using Dovecot 1.2.4 on a test server. The config is taken mostly verbatim from the expire plugin wiki page [1], using MySQL as a database. See below for detailed output. Namespace "private" has "/" configured as mailbox separator: namespace private { separator = / prefix = inbox = yes } The "expire =" section from dovecot.conf thus looks like this: plugin { expire = Trash 7 INBOX/Spam 8 INBOX/Spam/To-Discard 3 ... } Three mailboxes/folders are kept track of: Trash, INBOX/Spam and INBOX/Spam/Spam-To-Discard (this one holds messages that scored high enough to very unlikely be legitimate and should be deleted soon). But when a message is put into one of these folders the mailbox attribute of the expires table uses "." as mailbox separator: mysql> select * from expires; +-----------------+----------------------------+--------------+ | username | mailbox | expire_stamp | +-----------------+----------------------------+--------------+ | foo(a)example.org | INBOX.Spam.Spam-To-Discard | 1253114526 | | foo(a)example.org | INBOX.Spam | 1253114528 | +-----------------+----------------------------+--------------+ Consequently, expire-tool --test seems to choke on this: # dovecot --exec-mail ext /usr/local/libexec/dovecot/expire-tool --test Info: foo(a)example.org/INBOX.Spam.Spam-To-Discard: \ mailbox 'INBOX.Spam.Spam-To-Discard' removed from config Info: foo(a)example.org/INBOX.Spam: mailbox 'INBOX.Spam' \ removed from config When I manually update the mailbox attribute to use "/" as separator expire-tool seems to work correctly: # dovecot --exec-mail ext /usr/local/libexec/dovecot/expire-tool --test Info: foo(a)example.org/INBOX/Spam/Spam-To-Discard: stop, expire \ time in future: Wed Sep 16 17:22:06 2009 Using "." as separator in the "expire =" line doesn't work either: the expires table isn't written to at all when a message is put in one of the specified folders. Presumably because INBOX/Spam is the real mailbox but INBOX.Spam is monitored by the expire plugin and there is no INBOX.Spam to put in messages. So I believe this is not the expected behaviour? Or am I doing anything wrong? I'd rather not change the separator from "/" to "." in all the namespaces if that can be avoided.

[Dovecot] Error (IMHO) with --with-doc option
by Jacek Osiecki 16 Oct '09

16 Oct '09

Hi, I was trying to create complete rpm package for my system, containing dovecot 1.2.5 intregrated with dovecot-sieve and dovecot-managesieve. Finally I succeeded and it works great, but I found something that might be treated as wrong behaviour... When you run ./configure --with-docs=no, Makefile does not build docs anymore, but... installs them anyway :) It caused some troubles because rpmbuild complained about documents moved to <buildroot>/usr/share/doc/dovecot I have created a small patch that fixes this - hope it doesn't introduce any mess: diff -Nur 2/Makefile.in 1/Makefile.in --- 2/Makefile.in 2009-09-29 00:17:22.000000000 +0200 +++ 1/Makefile.in 2009-09-29 00:17:38.000000000 +0200 @@ -75,7 +75,7 @@ distclean-recursive maintainer-clean-recursive ETAGS = etags CTAGS = ctags -DIST_SUBDIRS = src doc +DIST_SUBDIRS = $(SUBDIRS) DISTFILES = $(DIST_COMMON) $(DIST_SOURCES) $(TEXINFOS) $(EXTRA_DIST) distdir = $(PACKAGE)-$(VERSION) top_distdir = $(distdir) Best regards, -- Jacek Osiecki joshua(a)ceti.pl GG:3828944 I don't want something I need.

[Dovecot] Questions regarding dbox migration
by Mikkel 16 Oct '09

16 Oct '09

It has been my wish to move to dbox for a long time hoping to reduce the number of writes which is really killing us. Now I wonder what may be the best way of doing so. I'm considering some sort of intermediate migration where the existing Maildir users are changed to single-dbox and then later upgraded to 2.0 and changed to multi-dbox when it becomes stable. But is this a reasonable task to perform on a production system or at all? The alternative is to wait for 2.0 to become completely stable and then go all the way at once. I would however much prefer to take it one step at a time and I think it would be safer to start out with single-dbox as it appears less complex. Now the big question is whether multi-dbox and single-dbox are compatible formats. If a Maildir->dbox migration is made on a system running dovecot v. 1.1, would it then be trivial later changing to multi-dbox after upgrading to 2.0 or is a completely new migration then needed? Would this scenario be much different if the system is upgraded to version 1.2 before the change to single-dbox? Kind regards, Mikkel

[Dovecot] dovecot 1.2.6 fails to build with openssl < 0.9.8
by Paul Howarth 16 Oct '09

16 Oct '09

The update of ssl_proxy_get_security_string() in dovecot 1.2.6 has broken compatibility with openssl < 0.9.8 (e.g. on RHEL4) because the functions SSL_COMP_get_name and SSL_get_current_compression don't exist until openssl 0.9.8 (build fails at link time due to these symbols being unresolved). I've worked around this by reverting the function to the 1.2.5 version for now but I think a better solution would be to have a configure test for these functions and only include the SSL compression details when they're available. Cheers, Paul.

[Dovecot] is it possible to fetch messages for multiple users using a single account?
by Tony Smith 16 Oct '09

16 Oct '09

Dear list, I am running dovecot with LDAP. Each account has email in form abc(a)example.com, and messages are stored at /var/vmail/abc/Maildir. This is an external mail server, and I would like to use a cron job to fetch all messages to an internal server which has slow internet connection. It seems getmail supports multidrop retriever which might fit the bill. However I could not figure out how to set up an account that can be used to fetch all messages for all virtual accounts. Is it possible at all? thanks, Tony PS: here is my config: # dovecot -n # 1.1.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-openvz-amd64 i686 Debian 5.0.3 log_path: /var/log/dovecot.log protocols: pop3 pop3s imap imaps managesieve listen(default): * listen(imap): * listen(pop3): * listen(managesieve): 127.0.0.1:2000 ssl_cert_file: /etc/ssl/certs/cert.pem ssl_key_file: /etc/ssl/private/key.pem disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login mail_uid: 1000 mail_gid: 1000 mail_location: maildir:/%Lh/Maildir/:INDEX=/%Lh/Maildir/ mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): quota imap_quota zlib mail_plugins(imap): quota imap_quota zlib mail_plugins(pop3): quota zlib mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 mail_plugin_dir(managesieve): /usr/lib/dovecot/modules/managesieve pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh pop3_client_workarounds(managesieve): sieve_storage(default): sieve_storage(imap): sieve_storage(pop3): sieve_storage(managesieve): /var/vmail/sieve/%Ld/%Ln/ sieve(default): sieve(imap): sieve(pop3): sieve(managesieve): dovecot.sieve auth default: mechanisms: plain login default_realm: river-valley.com user: vmail passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf socket: type: listen client: path: /var/spool/postfix/dovecot-auth mode: 438 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 438 user: vmail group: vmail plugin: quota_warning: storage=85%% /usr/bin/dovecot-quota-warning.sh 85 quota_warning2: storage=90%% /usr/bin/dovecot-quota-warning.sh 90 quota_warning3: storage=95%% /usr/bin/dovecot-quota-warning.sh 95 quota: maildir quota_rule: *:storage=100M expire: Trash 7 Trash/* 7 Junk 30 expire_dict: proxy::expire auth_socket_path: /var/run/dovecot/auth-master dict: expire: db:/var/lib/dovecot/expire/expire.db

[Dovecot] virtual Folder Plugin with "." Separator: [NONEXISTENT] Mailbox doesn't exist
by Elmar Weber 16 Oct '09

16 Oct '09

Hello, I've switched from courier-imap to dovecot to benefit from the virtual folder feature. I'm using dovecot 1.2.6 on Gentoo Linux. However, I', getting the message "[NONEXISTENT] Mailbox doesn't exist: <name>" from Thunderbird when I try to access any virtual folder. The relevant setup: mail_location = maildir:~/.maildir namespace private { separator = . inbox = yes hidden = yes list = yes } namespace private { prefix = virtual. separator = . location = virtual:~/.maildir/.virtual } I then created the folders ~user/.maildir/.virtual and ~user/.maildir/.virtual.test and placed a file in .virtual.test with the contents ====== * all ====== After a dovecot restart I'm getting the error message: "[NONEXISTENT] Mailbox doesn't exist: test" Where did I make the mistake in the configuration? Is the "." path separator a problem case? ciao, Elmar

[Dovecot] Missing folders
by John Moorhouse 16 Oct '09

16 Oct '09

I've recently had a oops with the system I was running dovecot on so have had to move it to a new machine, I've been able to retrieve the mbox files from the old machine, built the new machine and over wrote the new mbox files with the old one in maildir, connecting to the server via imap woeks but I can only see the mail in the inbox from the old mbox files, emails in sub directories (the sub directories arn't there), is there some command I need to run to get it to pass the mbox file to find the folders or it there another file I need to transfer form the old machine. (I'm assuming that all the emails for a user, including those in subfolders are within the single mbox file, particularly as I'm is very large) Thanks John
