[Dovecot] Understanding migrateuser.sh
by Stewart Dean 09 Feb '10

I'm sure it comes from my being a gormless idiot, but whatever is the -UKWS argument immediately after the mb2md.pl invocation? > $MB2MD -UKWS -s "$INBOX" -d "$WORKING" As always, reading the idiom of someone else's scripting is an education. And some of it wouldn't work with native AIX sh/ksh, so changed the functions: > folders_hash() { > local HASH=`find $FOLDERS -type f |sort|(IFS=\ > ;while read file; do ls -l "\$file"; done)` > eval "$1=\"$HASH\"" > } > to: > folders_hash() { > local IFS=\ > local HASH=`find $FOLDERS -type f | sort | \ > while read file > do > ls -l "\$file" > done` > # the escapes are so that $1 gets "$HASH" NOT $HASH > # So the resolution is deferred... > eval "$1=\"$HASH\"" > } I would have wished for a few more comments within the script. -- ==== Once upon a time, the Internet was a friendly, neighbors-helping-neighbors small town, and no one locked their doors. Now it's like an apartment in Bed-Stuy: you need three heavy duty pick-proof locks, one of those braces that goes from the lock to the floor, and bars on the windows.... ==== Stewart Dean, Unix System Admin, Bard College, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

by Nikolay Shopik 09 Feb '10

09 Feb '10

I'm running KDC with all users and passwords, but have to manage clients who doesn't support GSSAPI like mobile phones. Is it possible to dovecot SASL check password in KDC when user sends plain text login? I know this is possible to do with saslauthd from Cyrus but prefer to stick with dovecot SASL.

[Dovecot] Converting layouts
by Luciano Mannucci 09 Feb '10

09 Feb '10

Hello, I'm using dovecot 1.2.10 with mbox format (which implies layout=fs) and I would like to switch to maildir++ layout without changing format in order to implement subfolders for IMAP users. I understand that I should move the INDEX location to avoid some namespace conflict (it would be a good idea anyway: I'll move them on another disc :). Now I have mail_location = mbox:/var/spool/mailboxes/%u:INBOX=/var/spool/mail/%u in my /etc/dovecot.conf. I think it should become somethink like mail_location=mbox:/var/spool/mailboxes/%u:LAYOUT=Maildir++:INBOX=/var/spool/mail/%u:INDEX=/var/dovecot_indexes I'll have to rename folders for IMAP users, right? Is there some script that does just that? Some other needed black magic for .subscriptions? Thanks to all in advance, Luciano. -- /"\ /Via A.

[Dovecot] Problem with created ~/mail directory
by Chris Adams 08 Feb '10

08 Feb '10

If a user doesn't have a ~/mail directory and logs in, the directory is created for them. However, it is created with insecure permissions, 0770 (full group access). The problem is this bit in src/lib-storage/index/mbox/mbox-storage.c: #define CREATE_MODE 0770 /* umask() should limit it more */ The code then uses CREATE_MODE as an argument to mkdir_parents(), but mkdir_parents() overrides the umask setting and forces the requested permissions. There's no way to override this except to change the source code. It looks like the same thing is in dbox-storage.c and cydir-storage.c. This is with Dovecot 1.2.10. -- Chris Adams <cmadams(a)hiwaay.net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.

[Dovecot] Plugin question
by Valery Gorbunov 08 Feb '10

08 Feb '10

Hi All. I am developing plugin for Dovecot. And I needs for read some configuration file at startup and store configuration in application wide variable. As I see the plugin_init() method calls multiple times and allocates plugin's variables each time. Could you suggest better way to store variable in application context. Thank you Valery Gorbunov

[Dovecot] managesieve does call a wrong chown
by Wolfgang.Friebel＠desy.de 07 Feb '10

07 Feb '10

After upgrading from dovecot 1.2.3, managesieve 0.11.8, sieve 0.1.11 to dovecot 1.2.9, managesieve 0.11.10 and sieve 0.1.14 users who do not have sieve rules yet and use managesieve for the first time do trigger error messages in the log file (for the authenticated user ggg in group syspr): Jan 4 17:35:26 apollo dovecot: MANAGESIEVE(ggg): chown(/var/spool/sieve/ggg, -1, 0(root)) failed: Operation not permitted (egid=203(syspr)) Jan 4 17:35:26 apollo dovecot: MANAGESIEVE(ggg): sieve-storage: sieve_storage_verify_dir(/var/spool/sieve/ggg/tmp) failed: Operation not permitted Jan 4 17:35:26 apollo dovecot: MANAGESIEVE(ggg): Fatal: Failed to create sieve storage with data: /var/spool/sieve/ggg Anyway the filter rules get created (used avelsieve) and the filter does get compiled when the first mail hits the rule. Subsequent invocations of managesieve do not try to change the group ownership of the directory. Looks like an annoyance only, but I would feel more comfortable w.o. the error messages. the dovecot -n output: # 1.2.9: /etc/dovecot.conf # OS: Linux 2.6.18-164.6.1.el5 x86_64 Scientific Linux SL release 5.4 (Boron) protocols: imap imaps managesieve listen(default): * listen(imap): * listen(managesieve): *:2009 shutdown_clients: no login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(managesieve): /usr/libexec/dovecot/managesieve-login login_processes_count: 5 login_max_processes_count: 512 verbose_proctitle: yes mail_location: maildir:~/Maildir mmap_disable: yes fsync_disable: yes lock_method: dotlock maildir_copy_with_hardlinks: no mbox_read_locks: dotlock flock mbox_write_locks: dotlock flock mail_drop_priv_before_exec: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(managesieve): /usr/libexec/dovecot/managesieve mail_plugins(default): quota imap_quota zlib acl imap_acl listescape mail_plugins(imap): quota imap_quota zlib acl imap_acl listescape mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(managesieve): /usr/lib64/dovecot/managesieve imap_client_workarounds(default): delay-newmail netscape-eoh tb-extra-mailbox-sep outlook-idle imap_client_workarounds(imap): delay-newmail netscape-eoh tb-extra-mailbox-sep outlook-idle imap_client_workarounds(managesieve): namespace: type: private separator: / location: maildir:~/Maildir inbox: yes list: yes subscriptions: yes namespace: type: private separator: / prefix: #mbox/ location: mbox:~/mail:CONTROL=~/mboxctrl hidden: yes list: no subscriptions: yes lda: postmaster_address: postmaster(a)ifh.de mail_plugins: sieve quota acl sieve_global_path: /var/spool/sieve/default.sieve quota_full_tempfail: yes auth_socket_path: /var/run/dovecot/auth-master fsync_disable: no auth default: mechanisms: gssapi gss-spnego login plain realms: IFH.DE DESY.DE cache_size: 32 passdb: driver: pam args: max_requests=1 cache_key=%u userdb: driver: passwd-file args: /etc/userdb socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 master: path: /var/run/dovecot/auth-master mode: 438 plugin: quota: maildir:User Quota quota_rule: *:storage=1000MB quota_rule2: INBOX:storage=1000MB quota_rule3: Trash:ignore acl: vfile:/etc/dovecot-acls:cache_secs=300 acl_shared_dict: file:/var/spool/shared/shared-mailboxes.db sieve_storage: /var/spool/sieve/%u sieve: /var/spool/sieve/%u.sieve quota_warning: storage=95%% /usr/local/bin/mailquota-warning.sh 95 quota_warning2: storage=80%% /usr/local/bin/mailquota-warning.sh 80 quota_warning3: storage=60%% /usr/local/bin/mailquota-warning.sh 60 -- Wolfgang Friebel Deutsches Elektronen-Synchrotron DESY Phone/Fax: +49 33762 77372/216 Platanenallee 6 Mail: Wolfgang.Friebel AT desy.de D-15738 Zeuthen Germany
