[Dovecot] Only using LMTP-delivery, where should domain & user aliases be configured, Dovecot or MTA conf?
by mephistopheles＠operamail.com 05 Oct '11

05 Oct '11

I have my MTA (Postfix) check Dovecot2 LMTP for existing users. No other delivery is done; this is a virtual/LMTP-only setup. I define known users in a Dovecot passwd-file, specified in conf.d/10-auth.conf passdb { args = ... username_format=%n /stor01/vmail/auth.d/%d/passwd e.g., vi /stor01/vmail/auth.d/mx1.domain1.com/passwd myuser:{scheme}####:... mail to: myuser(a)mx1.domain1.com is correctly auth'd and stored. I want two things to happen: (1) all mail to existing-users "@domain1.com" gets re-routed to "@mx1.domain1.com", i.e., map: myuser(a)domain1.com -> myuser(a)mx1.domain1.com and is accepted/not-rejected ONLY if 'myuser' is defined as a user in mx1.domain1.com/passwd and, (2) specific 'user' aliasing/remapping within a given domain, i.e. map: whatever(a)mx1.domain1.com -> myuser(a)mx1.domain1.com as long as 'myuser' is a defined user in mx1.domain1.com In these cases, where should I assign domain & mail aliases, Dovecot or the MTA's conf ?

[Dovecot] trouble setting up director, "invalid argument" for connect() call
by Jim Lawson 05 Oct '11

05 Oct '11

Hi Timo & everyone, I'm trying out a 2-node director setup, but I keep getting the following error: Oct 3 16:11:29 imapdir1 dovecot: master: Dovecot v2.0.15 starting up (core dumps disabled) Oct 3 16:11:34 imapdir1 dovecot: director: Error: connect(132.198.100.150:9090) failed: Invalid argument Oct 3 16:11:41 imapdir1 last message repeated 3 times Both nodes report this error. The director on each node is listening on port 9090 just fine: > [root@imapdir1 ~]# nc imapdir2 9090 > VERSION director 1 0 > ME 127.0.0.1 9090 > [root@imapdir2 ~]# nc imapdir1 9090 > VERSION director 1 0 > ME 127.0.0.1 9090 "doveadm director ring status" always reports failure of the peer: > [root@imapdir1 ~]# doveadm director ring status > director ip port type last > failed > 127.0.0.1 9090 self > never > 132.198.100.150 9090 2011-10-04 > 13:28:55 > [root@imapdir2 ~]# doveadm director ring status > director ip port type last > failed > 127.0.0.1 9090 self > never > 132.198.100.149 9090 2011-10-04 > 13:24:08 Has anyone else seen this? FWIW, a single-node director works fine, proxying IMAP, LMTP and POP. I'm guessing I have a broken config, but if I do I can't figure it out. Hope I'm not missing something *too* obvious... Here's doveconf -n from imapdir1: # 2.0.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-274.3.1.el5 x86_64 Red Hat Enterprise Linux Server release 5.7 (Tikanga) base_dir = /var/run/dovecot/ director_mail_servers = penguina.uvm.edu penguinb.uvm.edu penguinc.uvm.edu director_servers = imapdir1.uvm.edu imapdir2.uvm.edu lmtp_proxy = yes login_trusted_networks = 132.198.101.211,132.198.101.212,132.198.101.213,132.198.101.214,132.198.101.215,132.198.101.216,132.198.100.45,132.198.100.46,132.198.100.47 passdb { args = proxy=y nopassword=y protocol=smtp driver = static } service auth { unix_listener auth-userdb { group = mail mode = 0660 user = dovecot } } service director { fifo_listener login/proxy-notify { mode = 0666 } inet_listener { port = 9090 } unix_listener director-userdb { mode = 0600 } unix_listener login/director { mode = 0666 } } service imap-login { executable = imap-login director } service lmtp { client_limit = 1 inet_listener lmtp { port = 24 } unix_listener /var/lib/dovecot/lmtp-socket { group = root mode = 0600 user = root } } Best, Jim

[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

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
