[Dovecot] user_filter problem
by sanito＠progresas.lt 20 Feb '12

20 Feb '12

Hello, I have a little bit complex setup. I'm trying to use dovecot lmtp and pop3 with user information stored in the LDAP database. The main problem is that email address and pop3 username are different for every mailbox (I cannot change this behaviour, because thousands of people already configured their email client for such a setup). So in my situation, user_filter for lmtp should be: user_filter=(mail=%u), but for pop3 it should be: user_filter=(cn=%u). Please, see: E-mail address: john(a)example.com pop3 username: 0005a pop3 password: very_secure_password And ldap ldiff for this mailbox: dn: cn=0005a,dc=example.com,ou=localmail,ou=mail uid: 0005a mail: john(a)example.com mailbox: /data/mail/example.com/0005a/Maildir/ sn: 0005a description: testing homeDirectory: /data/mail/example.com/0005a cn: 0005a userPassword:: e0NSWVBUfWxpOXBVaEw5SWJkRWc= objectClass: inetOrgPerson objectClass: CourierMailAccount objectClass: top I think I need to use different user_filter for lmtp and pop3, but it's not possible or I cannot find how to do it. Please, help! -- Best regards, dammit

by Ingo Thierack 20 Feb '12

20 Feb '12

Hello, try to use the new 2.1rc and don't get any data in the searchindex. Tried first lucene, and switched than back so solr. If I do an search in an mailfolder, i get in the dovecot-log 2012-02-06 22:17:11 | dovecot: | indexer-worker(xxxxxx): Indexed 0 messages in INBOX/dovecot Log from solr. Feb 6, 2012 10:17:11 PM org.apache.solr.core.SolrCore execute INFO: [] webapp=/solr path=/select params={fl=uid,score&sort=uid+asc&fq=%2Bbox:120ed10bbe9dcd4c8d2e0000f8146a47+%2Buser:"xxxxxxx"&q=body:"solr"&rows=9159} hits=0 status=0 QTime=1 Maybe I miss something. Upgraded from 2.0.15 to 2.1(head from repository yesterday) With 2.0 i see, if i start an search, solr had to work on the mail, now happens nothing. Upgrade the schema.xml, delete the old index.

[Dovecot] Homedir vs locations vs mail_location?
by Alexander Chekalin 20 Feb '12

20 Feb '12

Hello, I use Dovecot for rather long time, but I'm still in doubt for some small things. Here they are: 1. The homedir value points to the place where everything for the user stored at, while mail_location is something (some place) where mail stored at. if I deal with pure virtual users (all users are in sql tables and no system homes for them at all), should I ever care for returning meaningful value for 'homedir' (via password_query's userdb_home), or I can simple return empty or constant ('' or '123') for it and it won't mess anything? 2. If I use single (default) namespace, should I set namespace's location (to the same value as global mail_location), and should I expect anything strange if I skip it to set? Reversely, is it possible not to set global mail_location and set only namespace's location (which would be more logical as namespace definition is compact and easy to find in config)? I've reread my questions and see it is dummy ones, but I'd like to know that for sure. Thank you in advance, Alexander

[Dovecot] dovecot freezes when trying to get mail from maildir with mail
by postmaster 20 Feb '12

20 Feb '12

I'm completely stumped by this problem and I've tried everything at present - including installing dovecot from scratch. The problem is that when trying to get email from the server -AND- there's email in the account, the pop3 or imap process freezes and no email is fetched. The crazy thing is, that it has been working perfectly, but suddenly I'm getting these freezes both when using telnet from localhost, roundcubemail on the same server and Seamonkey from another computer. Logging seems to work perfectly. For an account without email, dovecot finds the maildir++ and acts correctly. For an account -with- email, dovecot seems to find the maildir++, but also seems to try Namespace of which I haven't defined any. I've tried to get rawlog to work also, but that didn't work - the telnet process froze on login even though I'm quite sure I did the right thing and ps showed an active rawlog process Postfix is delivering the email straight into the mailboxes.

[Dovecot] Something is strange - perhaps my AMD processors ?
by Finn B 20 Feb '12

20 Feb '12

Moi Timo / all. I've been using Dovecot on my Qmailtoaster production mailserver for some years - since 1.0.7 and current Version 2.0.10 - works perfectly. Now I am installing a backupsystem and a VM testsystem (2 boxes) - and no matter how and what Version I am installing on these 2 boxes I get below messages whenever I try to test connection with Telnet (localhost 110 / 995). I have tried to install all Dovecot versions from 2.010 to 2.018 as rpms, yums and as source and compiled it. It's on Centos5.7 (64) with Qmailtoaster (which I have installed as I have done many times before) I have tried to copy all my settings from my current production system (Centos 5.7, latest and greatest versions of qmailtoaster and Dovecot 2.0.10) - nothing helps. Now I come to think of it I realize that my production system is intel based and the 2 new ones are AMD based and wonder if this may be the case ? Dovecot.log master: Error: Service(auth): command startup failed, throttling log: Error: Service(auth): child 1859 returned error 89 (Fatal failure) pop3-login: Error: Timeout waiting for handshake from auth server. my pid=1858, input bytes=0 Regards, Finn B

[Dovecot] Questions still about a uw-imap -> dovecot conversion
by Steve Campbell 20 Feb '12

20 Feb '12

The more I read about all of this, the more I'm thinking about moving to maildir format. My switchover this weekend is full of holes due to the way user's imap folders were laid out. Some had folders in their home directory and others might have folders in their /home/mail directory. Some how, Horde/Imp seemed to keep track of it. Dovecot is not doing so well. I've been reading about the conversion technique to convert to maildir, but I'm wondering if I can do this based on the way our users are set up. Most are pop accounts. Our webmail is configured to read the inbox from /var/spool/mail and their imap folders from /home or /home/mail. Some have imap accounts on their desktop defined through their mail client. RH/Centos seems to want me to switch to postfix since most of the documentation I find doesn't mention Sendmail. My filesystem is laid out to handle Inboxes in /var/spool/mail and imap folders in /home(/mail) and these aren't logical volumes but true partitions, so I've got to consider this as I make any changes. I also run pop using dovecot, so I'll need to figure all this out. I've read the technique linked to on the dovecot site that points to "Replacing UW-IMAP with Dovecot on RHEL 3" written back in 2004, and that's about the only real pointers I'm finding. I don't want to have to go around to each machine and change their clients to IMAP.. Anyone care to comment on anything similar they've done and how many pitfalls they ran into and what they were? steve campbell

[Dovecot] A Postfix/Dovecot example with SQLite backend [crossposted]
by /dev/rob0 19 Feb '12

19 Feb '12

There are many mail howtos on the web ... can one more hurt? http://rob0.nodns4.us/howto/README http://rob0.nodns4.us/howto/ http://rob0.nodns4.us/howto/latest.tar.gz (all files) (Sorry, not HTML yet. That is on the agenda.) This is a multiple address class sample implementation of a Postfix MTA and Dovecot IMAP server using a SQLite3 data backend. Domain lookups, user maps, access and transport maps: all using a single, shared SQLite database file. What, other than the SQLite backend, distinguishes this from other mail system howtos? The Postfix high points include a complete implementation of all address classes and per-address transport(5) maps, virtual(8) UID/GID maps, and smtpd(8) recipient access(5) maps. (The latter is using smtpd_restriction_classes, which are not discussed in detail, but are implemented in an interesting way.) On the Dovecot side, it's mostly standard stuff. The SQL deny userdb implementation, and the seamless integration of system and SQL users, might be interesting. I think the database itself is the best part of this example. It's as close to "normalized" as I think it can reasonably be. A significant fact is that each revision of the system has tended to simplify the schema. That's a good sign, I think. One central Domain table lists all domains and hostnames to which the server makes reference. Likewise, a central Address table lists all addresses (with a pointer to the Domain table for each record.) The Alias table defines relationships between Address entries. (Both local(8) and virtual(5) alias maps exist in that table.) Comments and suggestions are welcome, on-list if it's topical to whichever list (please don't crosspost unless comments are relevant to both lists), or offlist to the address in the README file (or as detailed below.) Thanks for your interest. -- http://rob0.nodns4.us/ -- system administration and consulting Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:

[Dovecot] Automatic Debian packages for Dovecot v2.2.
by Stephan Bosch 19 Feb '12

19 Feb '12

Hi, For our testing enthusiasts I've created new automatic Debian repositories for Dovecot v2.2. Repositories are available for Debian oldstable, stable and testing, on both i386 and am64. Read the following wiki item for more information: http://wiki2.dovecot.org/PrebuiltBinaries#Automatically_Built_Packages The repository for Dovecot v1.2 has been defunct for a few months now and is expected to be removed soon. For the coming month or so, the builders at Xi will not be active during Dutch daytime. There are some issues with the virtual host's I/O performance that need to be resolved first. Regards, Stephan.

[Dovecot] I'm confused about my namespace parms
by Steve Campbell 18 Feb '12

18 Feb '12

Hi, I'm new to the list and to dovecot. I'm having a strange situation that provides no errors, so I'm having a little problem diagnosing what's going on. I've been running a Centos 3 mail server with sendmail for our company for quite a few years. I finally got approval for new servers this year and put Centos 6.2 on it. I'm sticking with sendmail, but that's not important. Up to this point, I've got all working fairly well. I've found that if I configure dovecot to use the mixed format (pop and imap INBOX in /var/spool/mail, Imap folders in /home/user/mail, two namespaces) as in the examples for "namespace", most works fine. Anyone who has used imap previously on our old system and work as if nothing has changed. Anyone who has never used Imap before can't seem to access the server using our webmail app (Horde/Imp). Dovecot is providing both pop and imap. An account that is set up from a normal mail client as imap has no problems as well. Sendmail is set up to create a new user in the /var/spool/mail folder. When I moved from the old server to the new server, I copied /home and /var/spool/mail to the new server - in other words, I kept the same scheme. There are no errors in the maillog, and it indicates that the user is getting logged in and out, but the return to Horde is that the user entered the wrong name or password. I'm thinking that this is probably due to how dovecot is trying to look for the imap folders, but the lack or any errors makes it a little difficult to diagnose. I'm fairly certain that what was installed on the old server was UW-Imap and was provided by the imap-2002 rpm. I tried using the examples for UW-Imap compatability but that didn't work at all. I haven't been able to figure out what's different about the old imap folder contents and what's missing in the newly created imap folders to allow Horde to access this account. I'll look at the Horde config to see if anything is there, but I'm cautious about changing anything that might break the current users' ability. Most of the accounts are set up as POP with the ability to see what's left on the server using Horde, webmail, and IMAP. Any help in tracing this down would really help. I think my biggest problem is I don't understand the "namespace" parameter as well as I should. So there it is. It seems I've got at least 3 areas to concentrate on.
