[Dovecot] doveadm mailbox subscribe wildcard
by Micah Anderson 07 Oct '11

07 Oct '11

Hi, I noticed that wildcards work like the following, as described in the man page: # doveadm mailbox list -s -u bob dovecot* dovecot dovecot/pigeonhole dovecot/pigeonhole/2.0 however, wildcard subscriptions don't work: # doveadm mailbox subscribe -u bob dovecot* # doveadm mailbox list -s -u bob dovecot* dovecot dovecot* dovecot/pigeonhole dovecot/pigeonhole/2.0 It seems I subscribed the non-existant mailbox called 'dovecot*' -- is there a better way to handle this? thanks! micah --

[Dovecot] I'm the ONLY user that can get mail
by Ed Hochman 06 Oct '11

06 Oct '11

Hi, I'm stumped. I can access the postfix server to read my mail. BUT I'm the only user that can. Everyone else get rejected. Here's the syslog entry for another user: ...dovecot: pop3-login: Disconnected (auth failed, 1 attempts): user=<jmarino>, method=PLAIN, rip=192.168.0.51, lip=192.168.0.189 And here's an entry for me: ...dovecot: pop3-login: Login: user=<ed>, method=PLAIN, rip=192.168.0.51, lip=192.168.0.189 So ONLY I am able to get my mail. And this is consistent. The other users and passwords are valid. I've re-set them just to be sure. I suspect it's a rights issue but I've checked the rights for all /var/mail files and they're all the same except the owner of the file is the actual owner. I also checked all the rights for the files in /etc/dovecot. They all look OK and they all have root/root for the owner and user. Since I installed the system and did all the editing of the configuration files it's possible, but unlikely, that I'm the owner or group of some key file. I've looked for that but found nothing suspicious. Is it possible I may have given myself root access? I don't see how. My UID is 1000. Does the fact I'm the first user (per my UID) make a difference? I would think not. So I'm stumped. I don't have a clue as to where to look or what to do next. Any thoughts will be greatly appreciated. This is Dovecot 1.2.15 on Ubuntu 11.04. A new/clean install. Plaintext passwords are allowed. Here's dovecot -n # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.38-11-generic i686 Ubuntu 11.04 protocols: pop3 disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/pop3-login mail_privileged_group: mail mbox_write_locks: fcntl dotlock mail_executable: /usr/lib/dovecot/pop3 mail_plugin_dir: /usr/lib/dovecot/modules/pop3 auth default: passdb: driver: passwd passdb: driver: passwd-file args: /etc/passwd.dovecot userdb: driver: passwd Thanks

[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...

[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
