[Dovecot] Automatic Debian Dovecot repository now also includes amd64 binary packages.
by Stephan Bosch 04 Jan '11

04 Jan '11

Hi, I've recently significantly improved the automated Dovecot Debian package builder. At the beginning it only produced i386 binaries for Debian testing. A few weeks back I added a slave builder that builds packages for Debian stable. Today I have extended the slave builder with support for multiple architectures and I've added amd64 binaries to the repository. The master builder still builds packages for testing/i386 every hour. The slaves check for new source packages about 20 minutes later. Read the following wiki page for more information and read it carefully when you are considering to use these packages: http://wiki.dovecot.org/PrebuiltBinaries#Automatically_Built_Packages Also, every day at four 'o clock in the morning, the latest source packages are uploaded to the openSUSE build service, which builds i386/amd64 binaries for several Ubuntu versions (experimental): http://download.opensuse.org/repositories/home:/sbosch:/ Regards, Stephan.

[Dovecot] Problem with requiring client certificates for external connections
by Frank Crawford 04 Jan '11

04 Jan '11

Folks, I'm trying to configure my dovecot installation to require client certificates for external/Internet connections, while still allowing my local network to not need certificates. This configuration is for Dovecot 2 (2.0.8 in Fedora 14), and I've tried to use the "remote" block to give different definitions for my local network vs the defaults. While most options seem to be set fine, if I set "auth_ssl_require_client_cert" to yes as the default, and reset it to no for my local network, dovecot still requests a client certificate and fails as one is not supplied. Am I correct that it can be reset in a "remote" block, or is it treated differently to other options? In fact do I have the configuration correct, as there doesn't really seem to be anything documenting "remote" or "remote_ip" or related items for Dovecot 2. Related to this, much of the documentation states that the variable is "ssl_require_client_cert", seems to be accepted by ignored, vs "auth_ssl_require_client_cert" which does have some effects. Also, in the configuration dump, it duplicates the netmask. The configuration is below, as generated with "dovecot -n". Regards Frank # 2.0.8: /etc/dovecot/dovecot.conf # OS: Linux 2.6.36.1 x86_64 Fedora release 14 (Laughlin) ext4 auth_ssl_require_client_cert = yes mail_location = maildir:/var/spool/maildir/%u managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date mbox_write_locks = fcntl passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = postmaster(a)crawford.emu.id.au ssl = required ssl_ca = </etc/pki/CA/cacert.pem ssl_cert = </etc/pki/tls/certs/dovecot.crt ssl_key = </etc/pki/tls/private/dovecot.key ssl_verify_client_cert = yes userdb { driver = passwd } protocol pop3 { pop3_uidl_format = %v.%u } remote 203.16.204.0/24/24 { auth_ssl_require_client_cert = no disable_plaintext_auth = no ssl = no ssl_verify_client_cert = no } remote fdd2:7aad:d478:1::/64/64 { auth_ssl_require_client_cert = no disable_plaintext_auth = no ssl = no ssl_verify_client_cert = no } remote 2001:44b8:62:140::/64/64 { auth_ssl_require_client_cert = no disable_plaintext_auth = no ssl = no ssl_verify_client_cert = no }

[Dovecot] Courier-mta with Dovecot LDA again
by komodo 04 Jan '11

04 Jan '11

Hi all Sorry for repost, but i don't believe that there is noone who know where the problem can be. At least developers should know :-) I have sent this post once, but without answer. I have setup dovecot lda instead of maildrop on my courier server. Delivery is working, sieve plugin too, but i can't figure out why lda can't send emails via sendmail (vacation). I always get error Error: Sendmail process terminated abnormally, exit status 67 And i know why, but i don't know how to setup lda to make it work . Here is .courier file where is redirect to lda. | /usr/libexec/dovecot/deliver -a $RECIPIENT -f $SENDER But the deliver does not pass recipient address to sendmail. Here is some output of strace execve("/usr/libexec/dovecot/deliver", ["/usr/libexec/dovecot/deliver", "-a", "komodo@somedomain", "-f", "someuser@somedomain"], [/* 22 vars */]) = 0 So it's clear that deliver have those variables, but then i can see this execve("/usr/sbin/sendmail", ["/usr/sbin/sendmail", "-i", "-f", "<>", "--", "someuser@somedomain"], [/* 2 vars */] <unfinished ...> And there is empty -f , so here is the problem. How should i setup this to make it work correctly ? Here is my config [root(a)OVZ.mail ~]# dovecot -n # 2.0.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-194.8.1.el5.028stab070.5 x86_64 CentOS release 5.5 (Final) disable_plaintext_auth = no hostname = ovzmail listen = 10.0.10.34 mail_location = maildir:~/Maildir managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date mbox_write_locks = fcntl namespace { inbox = yes location = prefix = INBOX. separator = . type = private } namespace { location = maildir:/home/shared/Maildir prefix = spam_learner. separator = . type = public } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap sieve ssl_cert = </etc/pki/dovecot/certs/server.pem ssl_key = </etc/pki/dovecot/private/server.pem userdb { driver = prefetch } protocol lda { mail_plugins = " sieve" } protocol imap { mail_max_userip_connections = 40 } Many thanks Martin

[Dovecot] Quota ignore subfolders
by Héctor Moreno Blanco 04 Jan '11

04 Jan '11

Hello, We have dovecot 2.0.8 in our servers with Scientific Linux SL release 5.2 (Boron). We want to ignore a mailbox and its child mailboxes. A few weeks ago Timo told me to do this in dovecot.conf, create a new namespace which will be the quotaless namespace and edit the quota: namespace { inbox = yes location = prefix = INBOX. separator = . type = private } namespace { location = maildir:%h/Maildir/carpeta1 prefix = carpeta1. separator = . type = private } plugin { quota = maildir:carpeta1:ns=INBOX. quota_warning = storage=75%% /usr/local/dovecot/bin/quota-warning.sh 75 quota_warning2 = storage=90%% /usr/local/dovecot/bin/quota-warning.sh 90 } We also have passdb and userdb with ldap, with dovecot-ldap.conf: pass_filter = (&(objectClass=qmailUser)(uid=%u)(accountActive=TRUE)) pass_attrs = uid=user,userPassword=password, mailQuotaSize=quota_rule=*:bytes=%$ user_attrs = mailMessageStore=home, mailQuotaSize=quota_rule=*:bytes=%$ user_filter = (&(objectClass=qmailUser)(|(mailAlternateAddress=%u)(mail=%u)(uid=%u))(accountActive=TRUE)) We also tried the easy solution which was to indicate a quota rule in order to ignore the mailbox but with no success. It still get every mailbox to calculate the quota. We set mail_debug=yes to see if there was any error, but everything seemed to be ok. Any suggestions? Thank you very much in advanced.

[Dovecot] Renaming IMAP folders does not affect children
by Johannes Simon 04 Jan '11

04 Jan '11

Hi, we're using dovecot2.0 since August and very happy with it. Just recently Thunderbird users reported problems when renaming folders, and it seems that RFC 2060 (sec. 6.3.5) requires children of a renamed folder to be renamed, too. This however does not happen: Talking IMAP I get: * LIST (\HasChildren) "." "INBOX.NNN1" * LIST (\HasNoChildren) "." "INBOX.NNN1.NNN1a" . rename "INBOX.NNN1" "INBOX.NNN2" * LIST (\HasNoChildren) "." "INBOX.NNN1.NNN1a" * LIST (\HasNoChildren) "." "INBOX.NNN2" There seems to be no problem the filesystem rights, since this works: . rename "INBOX.NNN1.NNN1a" "INBOX.NNN2.NNN1a" * LIST (\HasChildren) "." "INBOX.NNN2" * LIST (\HasNoChildren) "." "INBOX.NNN2.NNN1a" Am I misunderstanding RFC 2060, or is my config wrong (doveconf -n below), or could it be a bug? Cheers, Johannes # 2.0.8 (e030df616faf): /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-openvz-amd64 x86_64 Debian 5.0.7 default_client_limit = 2500 default_process_limit = 600 dotlock_use_excl = yes log_timestamp = "%Y-%m-%d %H:%M:%S " login_greeting = Dovecot 2 ready. mail_fsync = always mail_location = maildir:~/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = autocreate acl managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date mmap_disable = yes namespace { inbox = yes location = prefix = INBOX. separator = . type = private } namespace { list = yes location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u prefix = INBOX.shared.%%u. separator = . subscriptions = no type = shared } passdb { args = session=yes dovecot driver = pam } plugin { acl = vfile acl_shared_dict = file:/etc/dovecot/dict/shared-mailboxes autocreate = INBOX.Trash autocreate2 = INBOX.Junk autocreate3 = INBOX.Sent autocreate4 = INBOX.Junk_old autocreate5 = INBOX.Drafts autosubscribe = INBOX.Trash autosubscribe2 = INBOX.Junk autosubscribe3 = INBOX.Sent autosubscribe4 = INBOX.Drafts sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap pop3 service auth { unix_listener auth-userdb { mode = 0666 } } service dict { user = dovecot } service imap-postlogin { executable = script-login rawlog /etc/dovecot/postlogin.sh user = root } service imap { executable = imap imap-postlogin } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = blocking=yes driver = passwd } protocol imap { mail_max_userip_connections = 50 mail_plugins = autocreate acl imap_acl } protocol pop3 { mail_max_userip_connections = 3 }

[Dovecot] user xxx@mydomain.com doesn't exist
by G.Nau 04 Jan '11

04 Jan '11

new setup of Dovecot 2.0.8 with postfix local users are simply defined as Linux users named xxx, yyy et cetera; IMAP access is fine with that users. Postfix is delivering mails with two domains (to xxx(a)mydomain.com or xxx(a)mydomain.org) and these are rejected by dovecot with 550: user doesn't exist. I've tested the possible usernames with "doveadm user" xxx: okay xxx(a)mydoman.com: "userdb lookup: user xxx(a)mydomain.com doesn't exist" xxx(a)mydoman.org: "userdb lookup: user xxx(a)mydomain.org doesn't exist" Dovecot2 wiki says "Dovecot doesn't care much about domains in usernames" Okay, how to I get dovecot to ignore the domain part (or accept the two defined domains) when mails are delivered from postfix? Or do I have to configure Postfix to strip the domain part before delivering to dovecot? Regards Birte Nauer

[Dovecot] archiving
by PA 03 Jan '11

03 Jan '11

Hi, recently I installed the newest 2.x version of dovecot working with postfixadmin/mysql and it works great, thanks Timo, however I been reading dovecot's mailing list archived messages and haven't run across a good solution for archiving mail with dovecot. There was mention of using rsync but I was looking for incoming mail to be copied to another folder, maybe called archive J, in real time where the user would have only read access to the messages in the archive folder and the expire plug-in would delete messages older then x number of days. Does anyone have an suggestions on how I can implement this, I would also like to hear how some people were implement archiving if they do it differently. Also as far as shared calendars with dovecot what are my options. Sorry if it's a little off topic. Thanks, Paul
