[Dovecot] deliver w/quotas - MDN after accept mail?
by Ken A 30 Sep '07

30 Sep '07

I'm testing deliver with sendmail and fs quotas. On an over quota condition, deliver accepts the mail, deletes it, then issues a MDN immediately. Is there a way to get deliver to soft fail like procmail does with a 400 error and queue the mail, then let sendmail handle the MDN, following it's "confTO_QUEUEWARN" and "confTO_QUEUERETURN" ? Thanks, Ken -- Ken Anderson Pacific.Net

[Dovecot] Proxy setup between two servers
by Abhijit Hoskeri 30 Sep '07

30 Sep '07

Hi, I am trying to set up a proxy between two dovecot servers. I have the following set up here. Dovecot version: 1.0.rc15 dovecot -n: # /etc/dovecot/dovecot.conf info_log_path: /var/log/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: pop3 imap login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_extra_groups: mail mail_debug: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: verbose: yes debug: yes passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: prefetch In dovecot-ldap.conf: hosts = localhost dn = <dn> dnpass = <dnpass> sasl_bind = no auth_bind = yes ldap_version = 2 base = <ldap-base-dn> pass_attrs = uid=user,userPassword=password,homeDirectory=userdb_home,uidNumber=userdb_uid, gidNumber=userdb_gid,mailQuota=quota,mailHost=proxy If I set the mailHost attribute for a user as "localhost" or "127.0.0.1", I get the following error message in syslog: mail.err: Sep 27 13:01:06 dovecot: auth(default): Master request 5534.1 not found and at the same time, in info_log_path (/var/log/dovecot.log), I get the following messages: Info: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=127.0.0.1 rip=127.0.0.1 resp=<hidden> Info: auth(default): ldap(hoskeri,127.0.0.1): bind search: base=dc=deeproot,dc=co,dc=in filter=(&(objectClass=posixAccount)(uid=hoskeri)) Info: auth(default): ldap(hoskeri,127.0.0.1): result: uid(user)=hoskeri uidNumber(userdb_uid)=1004 homeDirectory(userdb_home)=/home/hoskeri mailHost(proxy)=127.0.0.1 gidNumber(userdb_gid)=1000 Info: auth(default): ldap(hoskeri,127.0.0.1): bind: dn=uid=hoskeri,ou=People,dc=deeproot,dc=co,dc=in Info: auth(default): client out: OK 1 user=hoskeri proxy pass=<hidden> # I notice that in the above line, proxy does not any value associated with it.

Also, I have another question. In the setup I need to do, I need to use the hostname itself for the mailhost, and not IPs, but I understand that it is not implemented and only IP addresses are acceptable. Any major reason why this is so? Could I help implement it? Thanks in advance... -Abhijit

[Dovecot] Testing sieve filter
by Cliff Meece 28 Sep '07

28 Sep '07

Hi, I am trying to get sieve working with dovecot. Dovecot itself is working fine, and I have the following config: root@master:/var/log# dovecot --version 1.0.rc2 root@master:/var/log# dovecot -n # /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_extra_groups: mail default_mail_env: maildir:/var/mail/%u auth default: passdb: driver: pam userdb: driver: passwd I have this in my lda protocol: mail_plugins = cmusieve And I have created a .dovecot.sieve in both ~ and /var/mail/$user/ that looks like this: require "fileinto"; if exists "X-Spam-Flag" { fileinto "Junk"; } No mail gets moved to the junk folder, nut it does arrive in my inbox with the X-SPAM-Flag: Yes header. How do I troubleshoot this? I don't see anywhere in the logs any errors or any mention whatsoever of filtering activity or failure. I have seen numerous pages on how to set this up, but they invariably focus on setting up virtual users, which I do not need, so it isn't clear which steps I can safely ignore. thanks in advance, Cliff

I'll upgrade if I need to, but that is the most current dpkg for my distribution, and I'd really rather not compile from source if I don't have to.

[Dovecot] Documentation to create plugins.
by "Fábio M. Catunda" 28 Sep '07

28 Sep '07

hi! Is there any documentation to guide me how to create a dovecot plugin? I'm trying to read the code, but I'm not a good C programmer. I have been able to copy the mail-log plugin into copy-log, edited about 4 lines of code, then I edited Makefiles and configure, now I'm able to compile, install and use my "new" plugin. Anyway, any help is appreciated. Thankz! !DSPAM:46fd34b1153407177711712!

I have it (deliver) in a restricted access folder as a standard safety precaution, but as most of these "jails" end up being only safe for a short time I have again gone back to using Postfix as the deliver. Timo has from time to time mentioned that he was thinking that deliver needed to be rewritten. hmmm. I still give you and Rich credit though, if you had not mentioned the ideas behind Sendmail and LDA, it would most likely taken much longer before I read that wiki entry and gave that approach a try, instead of trying to find the missing setting for changing groups that the error message wants fixed. > -- > Bill Cole > bill(a)scconsult.com > > > > ------------------------------ > > Message: 7 > Date: Thu, 27 Sep 2007 17:07:28 -1000 (HST) > From: Julian Cowley <julian(a)lava.net> > Subject: [Dovecot] Dovecot raw backtrace when copying to folder > To: dovecot(a)dovecot.org > Message-ID: <alpine.LRH.0.9999.0709271646190.28814(a)taurus.cesta.com> > Content-Type: TEXT/PLAIN; format=flowed; charset=US-ASCII > > Seeing a problem with a certain user causing dovecot to crash when > copying > mail to a folder.

[Dovecot] dovecot IMAPS + kmail
by Timothy Murphy 27 Sep '07

27 Sep '07

I notice that kmail does not allow an IMAP sub-folder to be created (from an IMAPS client). When I try, kmail says this cannot be done for one of the following reasons: Your access permissions may be inadequate to perform the requested operation on this resource. The location where the folder was to be created may not exist. A protocol error or incompatibility may have occurred. Is there any simple way of getting round this? KMail has no problem creating top-level IMAP folders.

[Dovecot] filtering when mail is moved to IMAP Inbox
by Rahul Amaram 27 Sep '07

27 Sep '07

Hi, I have been looking for a solution to this problem for quite sometime but just haven't got any. This is how my current set up is. I have a IMAP Server installed on my home server. It has various folders. I have configured Thunderbird in my laptop to connect to the IMAP Server and access mails. I have also configured Thunderbird to download mails from my GMail account using POP3. I have set up a filter in Thunderbird to move all my mails which come to my Local Folders "Inbox" to my IMAP Server's Inbox. Now here is my question - Is it possible to set up some rules in the IMAP Server (maybe sieve) so that I can filter the messages coming to its Inbox and move them to another folder? The whole idea is that I have control over when I want to fetch mails from my GMail account but at the same time the filtering rules for moving to custom folders should be stored on the server so that i do not replicate this in every client. Regards, Rahul. -- http://rahul.amaram.name
