[Dovecot] allow_nets
by CJ Teets 28 Feb '09

28 Feb '09

Hello, Im using Ubuntu 8.10 with Dovecot 1.0.10. I am using passwd files, not a MySQL database. I have 2 files, a "users" file, and a "passwd" file. I have added: allow_nets=10.1.10.1 to the end of a specific users entry in the users file. When that user tries to login, I get the following in the logs: dovecot: 2009-02-28 09:06:59 Error: IMAP(bob(a)mydomain.com): Ambiguous mail location setting, don't know what to do with it: allow_nets=10.1.10.1 (try prefixing it with mbox: or maildir:) dovecot: 2009-02-28 09:06:59 Error: IMAP(boo(a)mydomain.com): Mail storage creation failed with mail_location: allow_nets=10.1.10.1 dovecot: 2009-02-28 09:06:59 Error: child 4174 (imap) returned error 89 here is the line from my users file: bob@mydomain.com::5000:5000::/home/vmail/ mydomain.com/:/bin/false::allow_nets=10.1.10.1 here is the corresponding line from the passwd file: bob@oldschoolpunk.com:$1$evcHgrbC$BuyQRCspMzTpD8zkphxo0/ My goal is, that I want to allow this user to check email ONLY from the IP specified (i.e. 10.1.10.1) I just can't seem to get this working... Am I going about something the wrong way? Thanks!

[Dovecot] Custom flags in v1.0.15
by Pascal Mouret 28 Feb '09

28 Feb '09

Hello all, I'm having problems with setting custom flags on a dovecot imap setup, with mbox mail store. I was running v1.0rc15 on a Debian Etch box, upgraded recently to v1.0.15, but nothing changed. The problem : I read my mail using IMAP. In Thunderbird (various versions, current one being v2.0.0.19), I can set various message flags (Important, Personal, Work, ... mapped to IMAP as $Label4,$ $Label3, $Label2, ...). I read my mail from several machines, but all changes made on the message flags from one machine won't appear on the others !? Still I've read that those flags are supported in Dovecot. Actually, I logged the IMAP traffic, and saw that Dovecot claims to "handle" them. For instance, I added a flag to a message : Thunderbird > 621 uid store 35150 +FLAGS ($label4) Dovecot > * 6716 FETCH (UID 35150 FLAGS (\Seen \Recent $Label4)) Now, if I close TB, so that changes are written to the mbox file, and if I open that file on a the server with any text editor, the 'X-Keywords' line doesn't appear !? And as a matter of a fact, if I read my mail from any other machine, the flag isn't set ! Anyone knows where the problem can be ? Do I need to upgrade to v1.1 ? Or are custom flags actually supported in v1.0 (which I believe is the case) ? I browsed through the internet and searched the archives of this mailing list but didn't find any clue ... Any help would be much appreciated Thank you very much in advance Pascal Mouret -- Pascal Mouret Responsable du Service Informatique Polytech' Marseille, Université de Provence 60, rue Joliot-Curie / 13453 Marseille cedex 13 Mel : pascal.mouret(a)polytech.univ-mrs.fr Tel : 04 91 11 38 04 / Fax : 04 91 11 38 54

[Dovecot] Dovecot + Postfix Mail Forwarding Question
by Taras Hryniw 28 Feb '09

28 Feb '09

I have dovecot and postfix set up on debian lenny. Squirrelmail is used to access the mail. I put a .forward file in my user's home directory, and that sure gets the job done of forwarding email, but I need a copy saved on the local machine as well. How do I do that?

This: Feb 16 10:05:56 server dovecot: Panic: IMAP(user): file istream-tee.c: line 144 (i_stream_tee_read): assertion failed: (ret > 0) auth-worker died. That happened with Dovecot 1.1.4, 1.1.7 and 1.1.11, 1.1.7 was not with me, was with another user I found, on some mailing list. The problem occurred when copying or deleting messages, sometimes even viewing (Webmail). Since it's a production server, I compiled the latest 1.0.x and I'm using it. This particular server was running Ubuntu 8.04 (the default package is 1.0.x) and I upgraded to 8.10 (the default package is 1.1.x). > > > Is it possible to have Dovecot on one machine serving two different domains? > > Set up how? Do you want to use user@domain style usernames, or do you > want Dovecot to detect the domain based on the server's IP address? One dovecot server which receives mail to two domains and does not forward the mail anywhere, it's the final destination for the two of them. I already have usernames that are unique, by using Dovecot variables I have username~domain.org as the actual username/mailbox name. I want to have two mailbox roots, this way, even knowing that mailbox names are unique (john~domain.org != john~anotherdomain.org) and when authenticating (from what you wrote down here about passdb) john(a)domain.org will not be confused with john(a)anotherdomain.org, even so, I want all mailboxes from one domain to sit on a different mailbox root. > > > Is is possible to set a LDAP config to one domain and another > > LDAP config to the other (the auth part, I wan't users to reside > > on different bases on my LDAP tree, so search bases need to be > > different) > > Yes. You can just create two passdb ldap {}s. Ok, so, I have 3 aspects to consider: a) When mail arrives b) When user logs in to check mail c) Where mailboxes are located a) Since I can make mailbox names unique with Dovecot variables (mailbox name is "susan~domain.org" which is different from susan~anotherdomain.org) when mail arrives, the mail message will be saved to the correct mailbox (even if I have, under the same mailbox root, two users with "susan" as the login, but from different domains). b) Since you said, on Dovecot 1.0.x, I can have two passdb ldap{}'s, when the user logs in, he/she will be redirect to the right mailbox, not the "other susan". c) Ok, the two above give me the possibility to have all mailboxes, from the two domains, under the same mailbox root, users will be unique no matter the scenario (mail arriving, user checking mail), BUT, I would like to keep them separated anyways, is that possible to force that? > thanks! = Miata Convertible Tops Buy manufacturer direct from gahh, leader in high-quality convertible tops using original materials and attachments.

[Dovecot] Quota + Sieve
by Linux Advocate 27 Feb '09

27 Feb '09

Thanx to everybody's help , i have got a working combination of; - dovecot LDA - smtp auth thru dovecot sasl - postfix - virtual users in mysql - postfixadmin - thunderbird as the email client Just 2 additional questions - A. Sieve .............. With the imap filters in thunderbird, do i need to use sieve in dovecot? my initial observations/ findings say "no"? B. Quota ............. If i have not set quota in dovecot or postfix ( no quota related configuration ), may i then assume, the users have "unlimited storage" , limited only by the hardware/filesystem? I would like to have this feature ( just like unlimited storage in yahoo ) and just have a cron script running regularly to delete old emails ( for middle level, low level users ). Is such a strategy ok? regards, mgomez

From there it didn't take long to figure out that something had changed with update of Dovecot that no longer allowed this configuration line to work: mail_location: ~/Maildir and both in dovecot.conf and log I was warned to add the prefix "maildir"" With this everything seems to be fixed. I don't know whether this would be considered any kind of bug. The Debian package allowed me to upgrade Dovecot without warning me that the rules for mail_location had changed. Thanks for your help and hints, Paul

[Dovecot] internal raw storage - dovecot deliver in /tmp
by lejeczek 26 Feb '09

26 Feb '09

is it configurable anywhere on the runtime level, is it configurable at all selinux policy does not allow for transition between some domains that subsequently results in deliver not being granted permissions it needs to write to /tmp instead of compiling a policy module I wonder what is the matter with that raw storage and /tmp? cheers ___________________________________________________________ Try the all-new Yahoo!

[Dovecot] Quick question...
by dovecot＠segel.com 26 Feb '09

26 Feb '09

Hi, Here's the scenario. I want to set up a mailbox so that when mail sent to the address is piped to a processing application, instead of going to a mailbox. One way I can do this is to set up a mailbox and then have an application that checks to see if there's mail and then processes it. (Old school Unix script) Is there a way to set it up with dovecot? (Cleaner solution) Thx -Mike

[Dovecot] exim4 + dovecot + SquirrelMail virtualhosted on Debian
by Tim Legg 25 Feb '09

25 Feb '09

Hello, I have a Debian machine that is virtual-hosting 6 domains with exim4. I finally got exim4 working well enough where I can send and receive mail using the mail command on my machine. I would eventually like to have SquirrelMail (which requires IMAP) working on my website. For whatever reason, exim4 doesn't seem to support IMAP. I found out that Dovecot is a prominent IMAP server. So I installed the most current Dovecot package (1.0.rc15) in Debian. Something is broken though... As I log into SquirrelMail, I get an error message "Error connecting to IMAP server: localhost. 111 : Connection refused". To investigate, I decided to telnet localhost on port 143 and found out that yes, the connection is in fact refused. So what do I need to do in order to have dovecot listen on port 143? Also, I noticed when I restart dovecot... debian:/etc/dovecot# /etc/init.d/dovecot restart Restarting mail server: dovecotError: Can't use mail executable /usr/lib/dovecot/imap: No such file or directory I hope this isn't a serious problem. Thanks Tim Legg
