[Dovecot] Detecting duplicate messages with sieve
by Aleksandar Lazic 17 Sep '11

17 Sep '11

Dear Listmember, I use http://www.courier-mta.org/reformail.html for "Detecting duplicate messages" ### The -D option implements a simple way to delete duplicate messages in incoming mail. filename is a file that will be approximately 'len' bytes long. This file will be used by reformail to save message IDs seen in recent mail. reformail reads the message on standard input. If the message has a Message-ID: header that's already in the cache file, reformail terminates with the exit code set to 0. Otherwise, reformail terminates with the exit code set to 1. ### ### my entry in mailfilter `reformail -D 8192 $HOME/.msg.cache` if ($RETURNCODE == 0) { /^From: *!.*/ FROM1=${MATCH2} /^Subject: *!.*/ log "$FROM (${FROM1}) => Not Delivered duplicate MSG-ID. Subject ${MATCH2}\n" exit } ### Is there a similar feature in sieve or can I still use the upper setup? Another question is about to add this header line in every mail. xfilter "${REFORMAIL} -a\"Lines: $LINES\"" Thanks for your help. BR Aleks

[Dovecot] Sieve envelope :detail "to" "extention" does not deliver to fileinto destination

Dear Listmember. I resend this with different Subject so that the spamfilter does not drop the mail, I hope ;-) I try to migrate from my current courier-mta setup fo postfix dovecot setup. I use the following scirpt to filter to the destination mailbox. ### /var/vmail/none.at/al/.dovecot.sieve # from http://wiki.dovecot.org/LDA/Sieve require ["fileinto", "envelope", "subaddress", "include"]; include "lists.sieve"; if envelope :detail "to" "work" { fileinto "INBOX.work"; } ### ### /var/vmail/none.at/al/sieve/lists.sieve require ["fileinto", "subaddress", "envelope" ]; if envelope :detail "to" "pdnsusers" { fileinto "Lists.pdnsusers"; } ### postfix/master ### dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user}@${nexthop} -a ${original_recipient} # flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user}@${nexthop} -m ${extension} -a ${original_recipient} ### Log ### Sep 11 21:47:48 lvps46-163-74-15 postfix/smtpd[7788]: connect from Sep 11 21:48:12 lvps46-163-74-15 postfix/smtpd[7788]: 495EF9FECAF9: Sep 11 21:48:27 lvps46-163-74-15 postfix/cleanup[7795]: 495EF9FECAF9: message-id=<> Sep 11 21:48:27 lvps46-163-74-15 postfix/qmgr[7785]: 495EF9FECAF9: from=<al(a)bitrace.net>, size=268, nrcpt=1 (queue active) Sep 11 21:48:27 lvps46-163-74-15 dovecot: lda: Debug: Loading modules from directory: /usr/lib/dovecot/modules Sep 11 21:48:27 lvps46-163-74-15 dovecot: lda: Debug: Module loaded: /usr/lib/dovecot/modules/lib90_sieve_plugin.so Sep 11 21:48:27 lvps46-163-74-15 dovecot: lda: Debug: auth input: al(a)none.at uid=5000 gid=5000 home=/var/vmail/none.at/al Sep 11 21:48:27 lvps46-163-74-15 dovecot: lda(al(a)none.at): Debug: Effective uid=5000, gid=5000, home=/var/vmail/none.at/al Sep 11 21:48:27 lvps46-163-74-15 dovecot: lda(al(a)none.at): Debug: maildir: root exists (/var/vmail/none.at/al/Maildir) Sep 11 21:48:27 lvps46-163-74-15 dovecot: lda(al(a)none.at): Debug: maildir++: root=/var/vmail/none.at/al/Maildir, index=, control=, inbox=/var/vmail/none.at/al/Maildir, alt= Sep 11 21:48:27 lvps46-163-74-15 dovecot: lda(al(a)none.at): Debug: none: root=, index=, control=, inbox=, alt= Sep 11 21:48:27 lvps46-163-74-15 dovecot: lda(al(a)none.at): Debug: Destination address: al-pdnsuser(a)none.at (source: -a parameter) Sep 11 21:48:27 lvps46-163-74-15 dovecot: lda(al(a)none.at): Debug: sieve: using sieve path for user's script: /var/vmail/none.at/al/.dovecot.sieve Sep 11 21:48:27 lvps46-163-74-15 dovecot: lda(al(a)none.at): Debug: sieve: opening script /var/vmail/none.at/al/.dovecot.sieve Sep 11 21:48:27 lvps46-163-74-15 dovecot: lda(al(a)none.at): Debug: sieve: script binary /var/vmail/none.at/al/.dovecot.svbin successfully loaded Sep 11 21:48:27 lvps46-163-74-15 dovecot: lda(al(a)none.at): Debug: sieve: binary save: not saving binary /var/vmail/none.at/al/.dovecot.svbin, because it is already stored Sep 11 21:48:27 lvps46-163-74-15 dovecot: lda(al(a)none.at): Debug: sieve: executing script from /var/vmail/none.at/al/.dovecot.svbin Sep 11 21:48:27 lvps46-163-74-15 dovecot: lda(al(a)none.at): sieve: msgid=unspecified: stored mail into mailbox 'INBOX' Sep 11 21:48:27 lvps46-163-74-15 postfix/pipe[7797]: 495EF9FECAF9: to=<al-pdnsuser(a)none.at>, relay=dovecot, delay=28, delays=28/0.02/0/0.22, dsn=2.0.0, status=sent (delivered via dovecot service) Sep 11 21:48:27 lvps46-163-74-15 postfix/qmgr[7785]: 495EF9FECAF9: removed Sep 11 21:48:28 lvps46-163-74-15 postfix/smtpd[7788]: disconnect from xxx ### dovecot -n => attachment dovecot_-n ~#: egrep -v '^(#|$)' /etc/dovecot/dovecot-sql.conf #### driver = mysql connect = host=127.0.0.1 dbname=mailserver user=$USER \ password=$PASSWORD default_pass_scheme = PLAIN-MD5 password_query = SELECT user_email AS user, \ user_password AS password \ FROM virtual_users WHERE user_email='%u'; #### Due to the fact that I'am new to dovecot and sieve I hope anybody can help the solve this issue.

Ok, I thought I tested accessing the mailbox afterwards, too - but I probably had not. I have a more general problem now: shared mailboxes from any "non-INBOX" namespace are not available to other users. That's not only with virtual or imapc namespaces, but also tested with two Maildir ones: namespace personal { inbox = yes location = maildir:~/Maildir prefix = INBOX. type = private } namespace second { inbox = no location = maildir:~/Maildir2 prefix = INBOX.second. type = private } namespace others { type = shared separator = . prefix = INBOX.shared.%%u. location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u #location = maildir:/home/%%n/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = children } [...] I can as user1 SETACL INBOX.second.box ~user1/Maildir2/dovecot-acl-list contains "1316082286 box" ~user1/Maildir2/.box/dovecot-acl contains "user=testuser lrs" (as does ~user1/Maildir/.in2007/dovecot-acl) The shared mailboxes dict contains shared/shared-boxes/user/testuser/user1 1 But - as testuser - 0 list "" "*" * LIST (\HasChildren) "." "INBOX" * LIST (\HasNoChildren) "." "INBOX.test" * LIST (\HasNoChildren) "." "INBOX.second" * LIST (\Noselect \HasChildren) "." "INBOX.shared.user1" * LIST (\HasNoChildren) "." "INBOX.virtual" * LIST (\HasNoChildren) "." "INBOX.shared.user1.in2007" 0 OK List completed. INBOX.shared.user1.second.box is missing. Also 0 select INBOX.shared.user1.second.box * OK [CLOSED] Previous mailbox closed. 0 NO Mailbox doesn't exist: second.box Log shows then: Sep 15 12:39:48 host dovecot: imap(8796, testuser): Debug: acl vfile: file /etc/dovecot/global-acls/INBOX.shared.user1.second.box not found Sep 15 12:39:48 host dovecot: imap(8796, testuser): Debug: acl vfile: file /home/user1/Maildir/.second.box/dovecot-acl not found ... not searching for the acl file correctly.

[Dovecot] Shared folder not listing
by Tom Clark 16 Sep '11

16 Sep '11

Hi Timo, I've got a weird problem on our dovecot. We're trying to setup private shared folder access. I have 2 users. tom(a)mailbox.com and system(a)mailbox.com. I have set the ACL's on all the folders (and subfolders) on system(a)mailbox.com. However, I'm not getting any of them listed when I check tom(a)mailbox.com <mailto:tom@mailbox.com's> 's IMAP folders. Our configuration is below (we're migrating from Courier hence the INBOX.): In 10-mail.conf: namespace { type = private prefix = INBOX. separator = . inbox = yes list = yes hidden = yes } namespace { type = shared separator = . prefix = INBOX.Shared.%%u location = maildir:%%h/Maildir:INDEX=~/Maildir/Shared/%%u subscriptions = no list = children } mail_plugins = acl protocol imap { mail_plugins = $mail_plugins imap_acl } In 90-acl.conf: plugin { #acl = vfile:/etc/dovecot/acls:cache_secs=300 acl = vfile } # To let users LIST mailboxes shared by other users, Dovecot needs a # shared mailbox dictionary. For example: plugin { acl_shared_dict = file:/var/vpopmail/domains/%d/shared-mailboxes } Have I missed anthing!?!? Thanks in advance! Tom
