[Dovecot] Public mailboxes configuration to receive mails
by Didier Faugeron 17 Apr '09

17 Apr '09

Hello, I would like to know how to use Public mailboxes in my Dovecot environment (dovecot 1.2.beta4) Currently my dovecot server is only used for mailbox user. The Postfix master.cf is configured with the following line: "dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/deliver -d ${user}" Both dovecot and postfix use LDAP requests for authentication and users data retrieving. However I don't use userdb database to get the users home directory but an userdb static instruction : "args = uid=vmail gid=vmail home=/data/maildir/%1Lu/%Lu allow_all_users=yes" I have configured my dovecot.conf to create a namespace Public, and it works fine: an user who have read/write access(ACL) to a public mailbox can subscribe to it and read/copy mails. My problem is to deliver mails in this public mailbox. I don't know how to do it. Therefore, first question: is it possible to deliver mails to a public mailbox through the LDA/Postfix ? If yes, please could you tell me how to configure LDA/Postfix and Dovecot in order to accept and deliver mails to users mailboxes and to public mailboxes ? I assume that the main modifications should be done in the master.cf of Postfix. Could you please specify and clarify what modifications are required ? Find below my dovecot -n output and dovecot-ldap.conf. Thank you in advance for your help and your feedback.

[Dovecot] Could sharing a folder with other users cause a loss of emails?
by Alfred Nutile 17 Apr '09

17 Apr '09

we are trying to figure out how and email box is not empty. All we did was /mail/user1 /mail/user2 /mail/shared ln -s /mail/shared /mail/user1/shared ln -s /mail/shared /mail/user2/shared Perms are fine and people where dropping emails in here fine. We added a third one and the user also right clicked in their IMAP client and added a subfolder. It was around that time they where gone. Could any of these actions cause that? PS it is not a mbox layout. Thanks!

[Dovecot] Coredump using virtual folder.
by Matthias Rieber 17 Apr '09

17 Apr '09

Hi, I'm using dovecot 1.2rc2 and I have the following issues with the virtual folder: 1. The virtual folders are flagged with \Noselect and at least thunderbird does not offer to select them. Adding them to the subscriptions file works fine and the folder can be used after that. 2. Two basic virtual work just fine like: $ cat virtual/all/dovecot-virtual INBOX INBOX.Ordner.work.archive.* all and $ cat virtual/unseen/dovecot-virtual INBOX unseen But the third one does not work: $ cat virtual/talk/dovecot-virtual virtual.all inthread x-references2 x-mailbox INBOX The IMAP Client says Unkown server error, the server logs look like this: ... dovecot: Info: IMAP(matthias): virtual: data=~/Maildir/virtual dovecot: Info: IMAP(matthias): fs: root=/home/matthias/Maildir/virtual, index=, control=, inbox= dovecot: Info: IMAP(matthias): Namespace INBOX.: Using permissions from /home/matthias/Maildir: mode=0700 gid=-1 <access happens here> dovecot: Info: IMAP(matthias): Loading modules from directory: /usr/local/lib/dovecot/imap dovecot: Info: IMAP(matthias): Module loaded: /usr/local/lib/dovecot/imap/lib20_fts_plugin.so dovecot: Info: IMAP(matthias): Module loaded: /usr/local/lib/dovecot/imap/lib20_virtual_plugin.so dovecot: Info: IMAP(matthias): Module loaded: /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so dovecot: Info: IMAP(matthias): Module loaded: /usr/local/lib/dovecot/imap/lib21_fts_squat_plugin.so ... kind regards, matthias

[Dovecot] virtual domains with SQL auth + ntlm (winbind) auth for one of them...
by Tomasz Lutelmowski 16 Apr '09

16 Apr '09

Hello ! Is it possible to configure dovecot so it can use SQL authentication for set of domains, and ntlm authentication for one domain? In other words, I would like to authenticate all users (with user(a)domain.com as login) in SQL server, and if not found, then strip @windomain.com from login and fallback to pam->winbind authentication. So far i have in my dovecot.conf: auth_default_realm = windomain.com mechanisms = plain passdb sql { args = /etc/dovecot/dovecot-sql.conf } passdb pam { } passdb passwd { } userdb sql { args = /etc/dovecot/dovecot-sql.conf } userdb passwd { } userdb prefetch { } in pam.d/dovecot : auth required pam_nologin.so auth include system-auth-winbind account include system-auth-winbind session include system-auth-winbind With this configuration I can authenticate all users for virtual domains with logins user(a)domain.com - ok, then it fallbacks to pam - ok, but then it returns error (winbind uses only "user" or "DOMAIN\user" as login). After I set auth_username_format = %n I get opposite situation - I can authenticate users with pam, but I can't with SQL (it requires user@domain as login field). Unfortunately auth_default_realm = windomain.com is a must have (and most of the windows clients uses user(a)windomain.com as login anyway). Please help, I'm banging my head against keyboard since 3 days but still no idea how to do it. Best regards, Tomek

[Dovecot] dovecot SASL + Postfix no IMAP or POP3
by Roderick A. Anderson 16 Apr '09

16 Apr '09

A customer is suffering with an older version of a Windows "Mail Server" software that does not permit connections to _other_ ports (25 only). Several of the domains they host have users who's ISPs block port 25 so they can not send mail. They'd like to set up an outbound (relay?) SMTP server for those customers using per user(a)domain.tld authentication. Since I personally use Postfix with dovecot SASL I'd prefer doing the same for them. The only issue I see is how to "disable" IMAP and POP3 and use only the SASL authentication feature. I read that Timo is thinking to _someday_ :-) separate the SASL authentication from the rest of Dovecot, but in the mean time can I just leave out the IMAP and POP3 stuff from dovecot.conf, or is there a disable option? Of course I'll clamp the IMAP and POP3 ports down with iptables but it would be nice knowing Dovecot would just say go away or ignore those connections. Is anyone doing this or have any suggestions, thoughts, or ideas about it? \\||/ Rod --

[Dovecot] INBOX lost in virtual namespace
by Xueron Nee 16 Apr '09

16 Apr '09

Hi, I have set a virtual namespace to create Virtual POP3 INBOX follow: http://wiki.dovecot.org/Plugins/Virtual dovecot.conf: mail_location = maildir:~/Maildir # default namespace namespace private { separator = / prefix = list = yes hidden = no subscriptions = yes } # virtual mailbox, for pop3 namespace private { separator = / prefix = virtual/ location = virtual:~/Maildir/virtual:LAYOUT=maildir++ list = no hidden = yes } # Copy of the default namespace. We'll use this in dovecot-virtual file. namespace private { separator = / prefix = secret/ list = no hidden = yes subscriptions = no } # cat ~/Maildir/virtual/.INBOX/dovecot-virtual secret/* all but, the INBOX lost in secret/ namespace :( When list in IMAP: a1 list "" "*" * LIST (\HasNoChildren) "/" "Sent" * LIST (\HasNoChildren) "/" "Spam" * LIST (\HasNoChildren) "/" "Junk" * LIST (\HasNoChildren) "/" "Draft" * LIST (\HasNoChildren) "/" "Trash" * LIST (\HasNoChildren) "/" "INBOX" a1 OK List completed. a1 list "secret/" "*" * LIST (\HasNoChildren) "/" "secret/Sent" * LIST (\HasNoChildren) "/" "secret/Spam" * LIST (\HasNoChildren) "/" "secret/Junk" * LIST (\HasNoChildren) "/" "secret/Draft" * LIST (\HasNoChildren) "/" "secret/Trash" a1 OK List completed. INBOX lost, So, the virtual namespace for POP3 cannot see the messages in IMAP's INBOX. Am I doing anything wrong? Thanks.. -- Xueron Nee http://www.xueron.com

[Dovecot] help with ldap config
by Ricardo Kleemann 16 Apr '09

Hi, I've been using courier with ldap and I'm trying to configure dovecot to do the same. I'm not exactly sure how to setup the ldap binds and filters... Here's my dovecot info: # 1.0.10: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mail_debug: yes auth default: verbose: yes debug: yes passdb: driver: pam passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: ldap args: /etc/dovecot/dovecot-ldap-userdb.conf plugin: quota: maildir $ sudo grep -v '^ *$#.*$\?$' /etc/dovecot/dovecot-ldap.conf uris = ldap://ldap dn = cn=admin, dc=americasnet, dc=com dnpass = xxxxx auth_bind = yes auth_bind_userdn = uid=%u,ou=%d,dc=americasnet,dc=com ldap_version = 3 base = uid=%u,ou=%d,dc=americasnet,dc=com user_filter = (&(objectClass=posixAccount)(uid=%u,ou=%d)) So I try to login with an LDAP user, say ricardo(a)domain.com.
