[Dovecot] problems with dotlock
by Mark Hedges 04 Mar '09

04 Mar '09

I have to make dotlock work because this openwebmail thing only supports one of dotlock or flock, but procmail delivery does dotlock and fcntl. procmail correctly creates a dotlock file in /var/spool/mail/username.lock when delivering, I can watch this with `while :; do ls -la | grep lock; done`. It works fine when lock_method=fcntl, but no dotlock file shows up in /var/spool/mail. mbox_write_locks are working correctly with mbox_write_locks = dotlock fcntl, the dotlock file shows up in the user's mail directory. However, dotlocking /var/spool/mail doesn't work: $ ls -la /var/spool/mail total 44 drwxrwxr-x 2 root mail 4096 Feb 25 17:39 . $ grep mail_privileged_group /etc/mail/dovecot.conf mail_privileged_group = mail Feb 25 17:45:45 anubis dovecot: POP3(despam_test_anubis): Effective uid=511, gid=100 Feb 25 17:45:45 anubis dovecot: POP3(despam_test_anubis): mbox: data=/home/anubis/despam_test_anubis/mail:INBOX=/var/spool/mail/despam_test_anubis Feb 25 17:45:45 anubis dovecot: POP3(despam_test_anubis): mbox: root=/home/anubis/despam_test_anubis/mail, index=/home/anubis/despam_test_anubis/mail, inbox=/var/spool/mail/despam_test_anubis Feb 25 17:45:45 anubis dovecot: POP3(despam_test_anubis): file_lock_dotlock() failed with mbox file /var/spool/mail/despam_test_anubis: Permission denied Feb 25 17:45:45 anubis dovecot: POP3(despam_test_anubis): Couldn't open INBOX: Internal error occurred.

It also does not help to chmod +t /var/spool/mail. $ dovecot --version 1.0.7 kernel 2.6.18-92.1.22.el5 centos mmap_disable = yes (req'd for ~/mail dotlocks, makes no difference either way for /var/spool/mail) Any ideas? Thanks, Mark

[Dovecot] Forwarding with Dovecot
by Sawtooth500 02 Mar '09

02 Mar '09

I'm using Dovecot with Postfix as my MTA I need to set up forwarding with Dovecot. I create a .forward file in my user's home directory, and in the .forward file I put destination_email_address email(a)example.com. Well, it got delivered to the forwarded email just fine. But the sender also got an undeliverable email from the dovecot mailbox and a copy was not saved in the dovecot mailbox. I need emails forwarded, and a copy saved in the dovecot mailbox. Thanks in advance for the help! -- View this message in context: http://www.nabble.com/Forwarding-with-Dovecot-tp22244316p22244316.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Compilation Issue on Old Boxes with macro in src/master/main.c
by Kevin A. McGrail 28 Feb '09

28 Feb '09

I'm throwing an error compiling with a custom-compiled gcc 3.2.3 on one box. The configuration string is CC=/usr/local/gcc3.2.3/bin/gcc CPPFLAGS=-I/usr/local/ssl/include LDFLAGS=-L/usr/local/ssl/lib ./configure --with-ssl=openssl --with-ssldir=/usr/local/ssl/certs --with-pam --with-pop3d --sysconfdir=/etc --localstatedir=/var I've used this to compile on other older boxes with success. And I compared the command lines and they are identical. This is the error I get with src/master/main.c main.c:365:1: directives may not be used inside a macro argument main.c:364:16: unterminated argument list invoking macro "printf" main.c: In function `print_build_options': main.c:372: syntax error before string constant Changing the function to a simpler function without the ifdef's resolves the issue and dovecot compiles. I would really like to know why two boxes with the same compiler are failing on one but not the other. Perhaps there's some program or library or preprocessor or path or something out of whack. Especially since using gcc 2.96 on the same box works! However, I since this is a simple options output routine and (from my cursory read) there may be some standards issue with this technique, I've also patched the issue. http://www.peregrinehw.com/downloads/dovecot/dovecot-1.1.11-build_options_m… Thoughts?

[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
