[Dovecot] What best decision to make for flatfiles or SQL when I use Dovecot2 + Postfix together?
by terryjames9461＠mm.st 04 Oct '11

04 Oct '11

Hello, I'm moving my mail server from Exchange to an opensource one. After a bunch of reading, I decided on building a Dovecot2 + Postfix server in a VirtualUsers-only + Multiple-domains configuration. Since my messages will be stored by Dovecot, and the documentation is really good, I figured that it's smartest to configure Dovecot, then make Postfix 'fit' to it, sharing the data files that way. I read through lots of the Dovecot wiki for v2. There are many ways for storing the database data. My goal is to only have data in one instances, used by both Postfix & Dovecot. I'm a little confused about: to do that sharing-in-one-place, do I have to use SQL or can I use the flatfiles like passwd-db? I think for sure someone already decided the best approach for this, and maybe I'm not understanding the logic to it. The data I think I need to share are: users (user(a)domain.com) passwords user aliases (mapping user2(a)domain.com -> user1(a)domain.com) domains domain aliases (domain.com also receives email for domain2.com) And I think all of this can be in passwd-db in Dovecot. But I also want to make sure that Postfix ONLY accepts email for users/domains that exist, so it has to read that data too. Can I do this that way with the flatfiles? Or do I have to use the SQL approach? TJ

I got into this thread rather late so maybe I missed something here. If you have different policies for your interface, you can run two different instances of dovecot (with 2 different base directories and sets of configuration files). I haven't tried it, but maybe it's also possible have interface specific CAPA strings and remove STARTTLS. Dovecot will support unencrypted sessions over the localhost interface, but your webmail seems to opportunistcally use it when offered, so don't offer it. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Intermittent authentication failures
by Eric Shubert 03 Oct '11

03 Oct '11

I'm running dovecot with vpopmail. Here's the configuration: [root@wong log]# dovecot -n # 2.0.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-238.9.1.el5 i686 CentOS release 5.6 (Final) auth_cache_size = 32 M auth_mechanisms = plain login digest-md5 cram-md5 auth_username_format = %Lu first_valid_uid = 89 log_path = /var/log/dovecot.log login_greeting = Dovecot toaster ready. mail_fsync = always mail_nfs_index = yes mail_nfs_storage = yes mmap_disable = yes namespace { inbox = yes location = prefix = separator = . type = private } passdb { args = cache_key=%u webmail=127.0.0.1 driver = vpopmail } plugin/quota = maildir protocols = imap ssl_cert = </var/qmail/control/servercert.pem ssl_key = </var/qmail/control/servercert.pem userdb { args = cache_key=%u quota_template=quota_rule=*:backend=%q driver = vpopmail } protocol imap { imap_client_workarounds = delay-newmail } Most clients use TLS and PLAIN login for verification, which works flawlessly. I also run SquirrelMail that is slightly dated and has no TLS capability, so it is using CRAM-MD5. CRAM-MD5 works sometimes: Sep 30 08:15:43 imap-login: Info: Login: user=<userA(a)domain.com>, method=CRAM-MD5, rip=192.168.252.8, lip=192.168.252.14, mpid=20301 but (seemingly more frequently) the authentication fails: Sep 30 08:16:41 imap-login: Info: Aborted login (auth failed, 1 attempts): user=<userA(a)domain.com>, method=CRAM-MD5, rip=192.168.252.8, lip=192.168.252.14 I restarted dovecot, and that apparently cleared the problem for one user, but not others. Is this perhaps a bug in dovecot, or would the problem lie with vpopmail? TIA for any pointers. -- -Eric 'shubes'

[Dovecot] Multiple LDAP authentication servers
by Romer Ventura 03 Oct '11

03 Oct '11

Hello, We are performing a Domain migration and I was wondering if there was any way to get Dovecot to authenticate to more than 1 LDAP server? Currently dovecot is configure to query the "mail" attribute from Active Directory and when found it binds with the credentials the user provided. This works fine, but when migrating user accounts, they get disabled in the source domain so that the user can no longer log on to it. But disabling the account in the source domain, causes the user to be unable to use his email account. Is there any way to get dovecot to try a second LDAP server if the first one fails to authenticate..? ~# dovecot -n # 1.2.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.29-xs5.5.0.15 i686 Debian 5.0.4 ext3 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps imap ssl_cert_file: /etc/ssl/certs/smtpd.crt ssl_key_file: /etc/ssl/private/smtpd.key login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_user: postfix mail_privileged_group: mail mail_uid: vmail mail_gid: vmail mail_location: maildir:/srv/mail/vmail/%Ud/%Ln/Maildir mbox_write_locks: fcntl dotlock imap_client_workarounds: delay-newmail outlook-idle netscape-eoh lda: postmaster_address: postmaster(a)h-st.com auth_socket_path: /var/run/dovecot/auth-master log_path: /var/log/dovecot-deliver.log info_log_path: /var/log/dovecot-deliver-info.log auth default: mechanisms: plain login 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/private/auth-client mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail Thanks -------- Romer Ventura

[Dovecot] clarifications on shared mailboxes
by Frank Bonnet 03 Oct '11

03 Oct '11

Hello I need some clarifications on shared mailboxes. Actually we use MBOX format with "real" unix users , but I've been asked to create some shared mailboxes for some users who need to have some for their working groups. What would be the best way to create those shared mailboxes ? Would it be possible to create some "shared space" on the server in maildir format to get advantage of the last seen flag ? If yes some config examples would be a great help. See attach the doveconf -n output ( certificates names have been obscured ;-) ) Thank you.

[Dovecot] problem with getting outlook to work with IMAP server
by Daminto Lie 03 Oct '11

03 Oct '11

Hi, I am having difficulty in getting the outlook 2010 to connect to my server running on Ubuntu Server 10.04. I can login to Squirrelmail webmail, and am able to send & receive emails through squirrelmail with no problem whatsoever. However, this morning, I was trying to add a new account for the same user on Outlook 2010 and I got the following error from outlook as follows Send test e-mail message: Your outgoing (SMTP) e-mail server has reported an internal error. The server responded: 554 5.7.7 No Spoofing Allowed.
