[Dovecot] nfs_flush_fcntl
by Jon 30 Sep '07

30 Sep '07

Hi, It seems that after I upgraded to 1.1beta1 it takes a few seconds first time I access a folder and i get this error : fcntl(/mail2/home/jon/.Maildir/.INBOX.Pren/dovecot.index.cache, F_RDLCK) failed: Bad file descriptor. No errors after that and it works fine. is this expected. Is it ok to continue using this? Best regards - Jon

[Dovecot] v1.0 vs 1.1b re: Postfix and Dovecot LDA
by Jerry Yeager 30 Sep '07

30 Sep '07

In running the various 1.0.n versions of Dovecot's LDA with the instructions in the wiki for using LDA with Postfix [on OS X 10.4] things went well using the instructions as-is (no setuid problems). This changed in moving over to the 1.1 beta. The LDA refused to work failing with the error "setgroups() failed: Operation not permitted" as I mentioned in a previous message. After reading the exchange between Bill Cole and Rich Winkel and following up on this, it seems that the new 1.1b wants you to give the Deliver app specific setuid permission via: cd /path/to/where/dovecot's/deliver/is sudo chmod u+s deliver Then things worked as before. There was no need to give the group 's' permission nor to change ownership of deliver from the default root:staff or root:wheel or whomever... . The error message seems odd though. I am not sure if, overall, this means there is a problem in Dovecot 1.0.n or that things are being tightened up in 1.1b. Thanks Bill and Rich for the tip! Jerry Yeager

I don't see this as a problem at all (why create one when there's none to be found:): * Move message into Spam: it's a spam that should be reclassified. * Move message out of Spam: it's a ham that should be reclassified. Don't really care where the mail comes from or where it is moved. This is the beauty of it all, count the key or mouse clicks, can't be less than this:) * Using the expire plugin, the Spam folder will be emptied auto- matically in due time (typically 30 days maybe) without user intervention. All close to zero maintenance for sysadmin as well as end-user. > Well, by now I dont have much, but I really would like to know how to > find the filename of a message being copied from a folder to another. No such luck (I think): to my understanding (with the help of Johannes in previous reply in this thread), you'd have to create a temporary file with the mail message using tmpnam() + mail_get_stream() or similar, and then do your thing. I'm aiming towards that exact functionality: I want to be able to do training using "pristine" source (so I'll need the whole message), and keep the previous functionality using signatures. We'll see how it goes. Good Luck and thanks for your input /Lars

[Dovecot] Configure/install path overrides
by Remy Zandwijk 30 Sep '07

30 Sep '07

Hi, I'm building and installing dovecot on a Solaris 10 machine and therefore I want to install Dovecot in /opt/dovecot. Thus, I start configure with --prefix=/opt/dovecot. I also override things like 'libexecdir', 'docdir', etc. When calling make install, Dovecot is installed in /opt/dovecot, but for example the binary user files are installed in /opt/dovecot/bin/dovecot. The same for the docs, which are installed in /opt/dovecot/share/doc/dovecot. I think that's not quite nice and neat, so I call 'make install' like: make docdir=/opt/dovecot/share/doc install. But even then, the wiki stuff is still installed in /opt/dovecot/share/doc/dovecot/wiki in stead of /opt/dovecot/share/doc/wiki. Very anoying. My point is that ./configure should be able to override all paths, but since some paths are somehow hard-coded in the Makefile, this is impossible. Any chance this will (be) change(d) sometime? -Remy

[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

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.
