[Dovecot] NFS lock tester
by Timo Sirainen 26 Nov '07

26 Nov '07

Anyone who has NFS, could you test: http://dovecot.org/tmp/locktest.c 1. Compile: gcc locktest.c -o locktest -Wall -g 2. Start in server 1: ./locktest temp1 3. Start in server 2: ./locktest temp2 4. Server 1 might log "unlink() failed" error after starting the second locktest, ignore that. It starts writing something like: 1 successes 12 successes link() succeeded, but link count=1 12 successes What I'd like to know is what OS you use on your NFS clients, what NFS server you use and what errors does it give (errors being those "link() succeeded/failed, but .." messages). I'm getting that "link() succeeded, but link count=1" error with FreeBSD 6.2. So I'd like to know if this is a FreeBSD bug, NFS server bug or a more common NFS problem that I should work around..

[Dovecot] Small typo
by Abhijit Hoskeri 26 Nov '07

26 Nov '07

Hi, There is a small typo in src/lib/network.c line 624 return "A non-recovable name server error occurred"; should be return "A non-recoverable name server error occurred"; Sorry about the pedantry. BTW, I am getting this error whenever I am trying to resolve a name from inside dovecot, but I can using the system tools. I am trying to get the proxying code to use hostnames as well as IP addresses. -Abhijit.

[Dovecot] Wanting to seperate MTA and Imap
by Brent Clark 26 Nov '07

26 Nov '07

Hi Current my set up is that the MTA and Dovecot (maildir) is on the same machine. Ive been asked to seperate the services from the same machine (too would like to add a secondary MTA - but thats future ideas). I read the documentation on NFS, but from other sites i have read. Most say this is NOT the best solution. My question is, how do some of the fellow dovecot users,or other companys, e.g. google etc, pull this off. If you can assist in helping me fine a solution and too help me understand, I would greatfully appreciate it. Kind Regards Brent Clark

[Dovecot] libwrap-ing IMAP and POP logins
by Edgar Fuß 26 Nov '07

26 Nov '07

Since I've been using this for maybe a year now, maybe someone else is interested in restricting IMAP and POP logins via libwrap. In addition to the attached patch (against 1.0.5) to src/login-common/main.c, src/{imap,pop3}-login/Makefile.in have to be modified to link against libwrap. Of course, the option needs to be integrated into configure in the long run.

[Dovecot] Sieve regex never matches
by frank.kintrup＠fkware.de 26 Nov '07

26 Nov '07

Hi, I found the following code on the net which should redirect all mails to another address depending on the time of day (useful for forwarding mails to work): require ["regex"]; if allof (header :regex "date" "(08|09|10|11|12|13|14|15|16|17):..:..", not header :regex "date" "(sat|sun)") { redirect "address@work>"; keep; } To check and test I simplified the regex to match all mails within a certain hour: require ["regex"]; if header :regex "date" "20:..:.." { redirect "user@domain"; keep; } Both scripts compile fine, but their regex never match. Has anyone an idea why? I'm using Dovecot 1.0.0 on Debian Etch stable. Frank

[Dovecot] passdb ldap static values
by Harrison Metzger 26 Nov '07

26 Nov '07

Hello, In the pass_attrs field one can map ldap attributes to dovecot attributes. I'm wondering if I can map both ldap attribuets and static attributes to a dovecot value in the same passdb section. Also, I can't seem to find what other values (if any) can belong in the: passdb ldap { args = /path/filename } stanza. Are there any other options I can put in that stanza, I can't seem to find any on the wiki. Harrison Metzger

Bom dia, Pessoal eu tenho um servidor HP Proliant ML 110 com 4gb de memoria e processador Xeon. Minha distribuição é um Fedora Core 7 com Postfix + Procmail e este chama Spanassasim e Clamav Para IMAP, POP3 utilizo dovecot. Estava tendo o erro de Corrupted dovecot.index, atualizei da versao 1.05 para a 1.07 Agora o mesmo problema ocorre algumas messagens ficam presas na caixa e o usuario nao recebe atraves do outlook 2000 (pop3) e quando logo via IMAP alguns usuarios tem menssagens nao lidas que nao foram entregues por pop3 e no Maillog aparece: Nov 23 09:00:43 golf dovecot: IMAP(everli): Maildir /home/everli/Maildir sync: UID < next_uid (89 < 90, file = msg.BAwd:2,) Nov 23 09:00:43 golf dovecot: IMAP(everli): Disconnected: Mailbox is in inconsistent state, please relogin. Apos isso relogando ou clicando novamente na caixa de entrada e deslogando o dovecot entrega via POP3 essas menssagens nao lidas. Porque isso ? como resolvo esse problema pois a maioria utiliza outlook e não o IMAP Cordialmente; Kleyton Maia dos Santos ____________________________________________________________________________________ Get easy, one-click access to your favorites.

[Dovecot] imap process killed with signal 11
by Daniel 26 Nov '07

26 Nov '07

Hi! Using the latest cvs from HEAD, I'm experiencing problems after sending a message and the client is trying upload the message to the appropriate (Sent/Queue) folder. I get only one error in dovecot.log: dovecot: Nov 25 14:21:31 Error: child 19554 (imap) killed with signal 11 So my client disconnects, and asks for the password again, and in dovecot.info I get nothing, but the logs of the new connection attempt.

[Dovecot] recalculation of maildir Quota
by Ingo Rogalsky 26 Nov '07

26 Nov '07

Hello, I intend to use maildir Quota for measurement only, not for applying restrictions. Therefore I defined rather high values. That's working as expected. Nevertheless it's not useful, because the recalculation time is to high. This takes some minutes for my own mailaccount with 250.000 mails on a NFS storage. This would be to bad, but whilst this time, the Mailclient hangs. Probably our users woulnd't accept this. Can this be done in the background? Furthermore I noticed that recalculation occurs after the file maildirsize gets longer than 30 lines (around 250-300 bytes) and not after 5120 bytes as the wiki states. Do I do/understand something wrong or is this a bug? Probably a nightly cronjob, which does calculation of Maildir-size would be a more useful alternative. Regards, Ingo Rogalsky

[Dovecot] migrating from mbox to maildir
by Erick Perez 26 Nov '07

26 Nov '07

Hi all, I have a locking problem in a Centos 4.4 linux machine with the following config: dovecot-0.99.11-8.EL4 postfix-2.2.10-1.1.el4 I use virtual mailboxes with postfix currently I have dovecot with mbox as this: default_mail_env = mbox:/var/mail/virtualmail/%d/%n The problem is that mail is being delivered to mailboxes very very slowly (sometimes up to 4 hours). In my logs, I have tons of these messages: mail postfix/virtual[24965]: CFB8878D04F: to=<REMOVED@REMOVED>, relay=virtual, delay=51, status=deferred (mailbox /var/spool/mail/virtualmail/REMOVEDDOMAINNAME/npitti: unable to lock for exclusive access: Resource temporarily unavailable) then someone told me that I need to change dovecot to maildir format. Is there a reference to change format? Or some comments about this? Thanks in advance.
