Was there a doveadm command that checks the SIS files and removes any not referenced? Will the "doveadm purge -A" catch that? -- Daniel

[Dovecot] Sieve doesn't find user scripts
by Jochen Spieker 30 Apr '12

30 Apr '12

Hi, I want to use Sieve filtering with my Dovecot 1.2 installation on Debian squeeze. I have a virtual domain setup using Portgresql. ManageSieve works fine so far, I can edit and activate/deactive scripts (using Thunderbird + Plugin) and they show up in the filesystem where I expect them to be, see below. The problem is that LDA doesn't find the script. From /var/log/dovecot-deliver.log: | 2012-04-29 12:17:48 deliver(jrspieker(a)well-adjusted.de): Info: Loading modules from directory: /usr/lib/dovecot/modules/lda | 2012-04-29 12:17:48 deliver(jrspieker(a)well-adjusted.de): Info: Module loaded: /usr/lib/dovecot/modules/lda/lib10_quota_plugin.so | 2012-04-29 12:17:48 deliver(jrspieker(a)well-adjusted.de): Info: Module loaded: /usr/lib/dovecot/modules/lda/lib90_sieve_plugin.so | 2012-04-29 12:17:48 deliver(jrspieker(a)well-adjusted.de): Info: auth input: mail=maildir:/srv/mail/well-adjusted.de/jrspieker | 2012-04-29 12:17:48 deliver(jrspieker(a)well-adjusted.de): Info: auth input: userdb_home=/srv/mail/home/well-adjusted.de/jrspieker | 2012-04-29 12:17:48 deliver(jrspieker(a)well-adjusted.de): Info: auth input: uid=105 | 2012-04-29 12:17:48 deliver(jrspieker(a)well-adjusted.de): Info: auth input: gid=109 | 2012-04-29 12:17:48 deliver(jrspieker(a)well-adjusted.de): Info: Quota root: name=storage=512000 backend=maildir args= | 2012-04-29 12:17:48 deliver(jrspieker(a)well-adjusted.de): Info: maildir: data=/srv/mail/well-adjusted.de/jrspieker | 2012-04-29 12:17:48 deliver(jrspieker(a)well-adjusted.de): Info: maildir++: root=/srv/mail/well-adjusted.de/jrspieker, index=, control=, inbox= | 2012-04-29 12:17:48 deliver(jrspieker(a)well-adjusted.de): Info: sieve: user has no valid personal script | 2012-04-29 12:17:48 deliver(jrspieker(a)well-adjusted.de): Info: sieve: no scripts to execute: reverting to default delivery.

[Dovecot] Refiltering mails without loosing flags
by Dieter Knopf 30 Apr '12

30 Apr '12

Hello, is there a way to refilter all mails in a folder without loosing all flags and moving all messages in a different folder? I have >10k mails in my Inbox and need to create new filterrules from time to time. But there is no way to refilter my inbox without moving. Atm i need to move all mails in a folder like "refilter" and then run getmail/... to refilter the mails. It would be really nice to refilter a existing folder and just move mails with hits in the filter list. Thanks Dieter

[Dovecot] setacl fails - does not find dovecot-acl file
by Michael Stilkerich 29 Apr '12

29 Apr '12

Hi, I'm using dovecot 2.0.13 that ships with Ubuntu 11.10. I tried setting up a shared namespace as documented in the wiki to enable the sharing of a mailbox between two users. I have a Maildir(++) directory for each user. Each user has a system account. The Maildir of each user is owned by the user's system account and group read/writable by the group mail (hence mail_access_groups=mail). Relevant parts of my config: mail_plugins = acl mail_location = maildir:/home/dovecot/%u mail_access_groups = mail namespace { type = private separator = / prefix = inbox = yes hidden = no subscriptions = yes } namespace { type = shared separator = / prefix = shared/%%u/ location = maildir:/home/dovecot/%%u:INDEX=/home/dovecot/%u/shared/%%u subscriptions = no list = children } protocol imap { mail_plugins = $mail_plugins imap_acl } plugin { acl = vfile } plugin { acl_shared_dict = file:/home/dovecot/shared-mailboxes } When I try to create an ACL in a telnet session, the command fails with an internal error. The log shows: dovecot: imap(michael): Error: fstat(/home/dovecot/michael/.test/dovecot-acl.lock) failed: No such file or directory dovecot: imap(michael): Error: file_dotlock_open(/home/dovecot/michael/.test/dovecot-acl) failed: No such file or directory The error occurs whether a (manually created) dovecot-acl file exists or not. The dovecot-acl.lock file is created by not removed afterwards. Subsequent setacl commands will timeout waiting for the lock to be released until I delete it manually. If I create the dovecot-acl file manually and provide access to another user, the getacl command will correctly show the permissions and the other user can access the folder. setacl will still fail to modify the acl file, however (same error). Another thing that irritates me is that dovecot seems to use the dotlock locking method, although I explicitly set lock_method to fcntl (also tried flock, same behavior). I'm not using chroot. I appreciate any help to get this sorted out. Thanks, Michael

[Dovecot] help with AES_DECRYPT and password lookup - mysql password_query
by jeep＠rahul.net 29 Apr '12

29 Apr '12

Hello- Sorry if this is a noob question, but I cant seem to get my password_query to work with dovecot + mysql. Im using 'Password verification by SQL server' at: http://wiki2.dovecot.org/AuthDatabase/SQL trying to modify it to work with my encrypted passwords in the DB. Im using the following which isnt working: password_query = SELECT NULL AS password, \ 'Y' as nopassword, userid AS user \ FROM users WHERE userid='%u' AND AES_DECRYPT(password, 'mykey')=password 1. Is it even possible to do this via 'password_query'? 2. If so, what am I doing wrong? Thanks, Jeff /mf/home/jeep/shell/.signature

[Dovecot] Session IDs
by Timo Sirainen 28 Apr '12

28 Apr '12

v2.1.2 added support for "session IDs", which is a 9 year unique identifier for that specific IMAP/POP3 connection. Initially I thought it would only be useful for tracking connections going through Dovecot proxies to backends (the session ID is forwarded), but then I thought it could be useful for everyone if auth process also logs the session ID. So I thought for v2.1.6 I'd change the defaults: a) Failed login: Apr 28 17:37:23 auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=XtG7KL6+jQB/AAAB lip=127.0.0.1 rip=127.0.0.1 lport=143 rport=42125 resp=<hidden> Apr 28 17:37:23 auth: Debug: passwd-file(foo,127.0.0.1,<XtG7KL6+jQB/AAAB>): lookup: user=foo file=/usr/local/etc/passwd.imap Apr 28 17:37:23 auth: Info: passwd-file(foo,127.0.0.1,<XtG7KL6+jQB/AAAB>): unknown user Apr 28 17:37:25 auth: Debug: client out: FAIL 1 user=foo Apr 28 17:37:50 imap-login: Info: Aborted login (auth failed, 1 attempts in 27 secs): user=<foo>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured, session=<XtG7KL6+jQB/AAAB> b) Successful login: Apr 28 17:38:27 auth: Debug: client in: AUTH 2 PLAIN service=imap secured session=rNuHLL6+jgB/AAAB lip=127.0.0.1 rip=127.0.0.1 lport=143 rport=42126 resp=<hidden> Apr 28 17:38:27 auth: Debug: passwd-file(tss,127.0.0.1,<rNuHLL6+jgB/AAAB>): lookup: user=tss file=/usr/local/etc/passwd.imap Apr 28 17:38:27 auth: Debug: client out: OK 2 user=tss Apr 28 17:38:27 auth: Debug: master in: REQUEST 1375993857 14321 2 0f2f78deedcb7e38a278cf79819360c5 Apr 28 17:38:27 auth: Debug: passwd-file(tss,127.0.0.1,<rNuHLL6+jgB/AAAB>): lookup: user=tss file=/usr/local/etc/passwd.imap Apr 28 17:38:27 auth: Debug: master out: USER 1375993857 tss uid=1000 gid=1000 home=/home/tss Apr 28 17:38:27 imap-login: Info: Login: user=<tss>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=14338, secured, session=<rNuHLL6+jgB/AAAB> .. Apr 28 17:47:15 imap(tss,<rNuHLL6+jgB/AAAB>): Info: Disconnected: Logged out in=8 out=369 The last line requires a modified mail_log_prefix, I wasn't planning on changing its default. I'm mainly wondering: 1) Does this change break someone's auth log line parsing? 2) Does the auth prefix look prettier with or without <> around session id? :) 3) Anything else I should do about this now that I'm changing it anyway?
