by k bah 27 Mar '08

Dovecot version dovecot-1.0.rc14-7 (opensuse) Postfix is using Dovecot LDA. I'm getting this error message, and I guess it's going to be a problem on my next task, which is to set up sieve scripts. Is there something wrong/contraditory on my config or I forgot something? I want: /var/dovecot-tests/: where user's inbox resides /var/dovecot-tests/home/: home dir (users will not be system users, this home is for sieve) /var/dovecot-tests/data/: mbox --- error msg --- ---

[Dovecot] Moving main inbox file from /var/mail to ~/mail
by Romain 26 Mar '08

26 Mar '08

Hi list, I am using Dovecot version 1.0.10 in a Debian package. At the moment, i have the main INBOX of each user in /var/mail/%u and others mboxes in ~/mail/. Here is the line coming from my /etc/dovecot/dovecont.conf mail_location = mbox:~/mail:INBOX=/var/mail/%u I would like to move the main inbox in each home folder with the rest of the others mboxes. What should be the process ? Should i only tkahe the network down, update my conf file and move the inbox of every user ? Or do I have to do something different ? Thanks Regards Romain romain(at)abakila(dot)net

[Dovecot] Changing the order of plugin execution.
by "Fábio M. Catunda" 25 Mar '08

25 Mar '08

Hi! I'm using an acl to avoid deletion of .Trash messages, but I also have mail_log plugin enabled, but I found out some logs of deletion on info.log: deleted: uid=218, msgid=<200802150943.25163.alessio(a)skye.it>, box=Trash The message is still there, but maillog logged that it have been deleted. I believe that this issue is related to the order that plugins are executes, is there a way to change it? dovecot version 1.0.13-1 debian package. Thanks!

Hello, I use a simple sieve file like: require "fileinto"; if header :contains ["From"] ["root"] { redirect "test(a)domain.com"; } When I send an email with root to this user, I have this error in my deliver log: Mar 12 09:43:18 helm deliver(user(a)domain.net): open(~/.temp.hostname.net.53398.23c1b1a363c2c4e8) failed: No such file or directory Mar 12 09:43:18 helm deliver(user(a)domain.net): msgid=<20080312084317.C01BD37FEC13(a)hostname.com>: forwarded to <test(a)domain.com> Why I have this error? I don't understand it. I use dovecot with Postfix (2.4) and FreeBSD (6.2) : dovecot-1.0.12 Secure and compact IMAP and POP3 servers dovecot-sieve-1.0.2 A sieve plugin for the Dovecot LDA called 'deliver' See my config a sieve in my dovecot.conf: mail_plugins = cmusieve quota (in protocol lda) sieve = /var/mail/vmail/%u/sieve (in plugin) Thanks for your help. - Nicolas.
