Public folder subscriptions with Outlook
by Paul Tansom 08 Sep '15

08 Sep '15

This is more an Outlook issue than Dovecot, but given that it is connected to Dovecot I figured there would be a good pool of knowledge here that increases the likelihood that somebody knows the answer :) I have a Dovecot server setup with a public folder and keep getting complaints that Outlook users don't see new folders created by other people. In Thunderbird it is simply a case of unchecking the box to only show subscribed folders, but I can't find a way to do this in Outlook. The only thing I can think of is putting a script on the server to check for new folders and update each users subcriptions file, but I'm not completely happy with that solution! Any suggestions welcome. -- Paul Tansom | Aptanet Ltd. | https://www.aptanet.com/ | 023 9238 0001 Vice Chair, FSB Portsmouth & SE Hampshire Branch | http://www.fsb.org.uk/ ============================================================================= Registered in England | Company No: 4905028 | Registered Office: Ralls House, Parklands Business Park, Forrest Road, Denmead, Waterlooville, Hants, PO7 6XP

Different behavior of ACLs in MUA and doveadm
by Thomas Leuxner 08 Sep '15

08 Sep '15

I have noticed a difference in the behavior of ACLs. When used in a MUA the following global ACL works fine and has the desired effect - new mailboxes can be created by a user being part of the 'PublicMailboxAdmins' group: [ global-acl: ] INBOX owner lrwstiekxap Public/* group=PublicMailboxAdmins lrwsipk Public/* anyone lr Public/* authenticated lrws Creating the same mailbox via doveadm however fails with a permission problem: doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: Namespace : type=public, prefix=Public/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=no location=mdbox:/var/vmail/public:INDEXPVT=~/mdbox/public doveadm(tlx(a)leuxner.net): Debug: fs: root=/var/vmail/public, index=, indexpvt=/var/vmail/domains/leuxner.net/tlx/mdbox/public, control=, inbox=, alt= doveadm(tlx(a)leuxner.net): Debug: acl: initializing backend with data: vfile:/var/vmail/conf.d/leuxner.net/global-acl:cache_secs=300 doveadm(tlx(a)leuxner.net): Debug: acl: acl username = tlx(a)leuxner.net doveadm(tlx(a)leuxner.net): Debug: acl: owner = 0 doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: Namespace : type=private, prefix=Virtual/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes location=virtual:~/mdbox/virtual doveadm(tlx(a)leuxner.net): Debug: fs: root=/var/vmail/domains/leuxner.net/tlx/mdbox/virtual, index=, indexpvt=, control=, inbox=, alt= doveadm(tlx(a)leuxner.net): Debug: acl: initializing backend with data: vfile:/var/vmail/conf.d/leuxner.net/global-acl:cache_secs=300 doveadm(tlx(a)leuxner.net): Debug: acl: acl username = tlx(a)leuxner.net doveadm(tlx(a)leuxner.net): Debug: acl: owner = 1 doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/dovecot-acl not found doveadm(tlx(a)leuxner.net): Error: Can't create mailbox Public/Archive/Newsletters/heise-security/2014: Permission denied Interestingly, doveadm succeeds when dovecot-acl is present in the namespace root - which of course is not desirable in the light of the global ACL: [ dovecot-acl: ] group=PublicMailboxAdmins lrwsipk doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: Namespace : type=public, prefix=Public/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=no location=mdbox:/var/vmail/public:INDEXPVT=~/mdbox/public doveadm(tlx(a)leuxner.net): Debug: fs: root=/var/vmail/public, index=, indexpvt=/var/vmail/domains/leuxner.net/tlx/mdbox/public, control=, inbox=, alt= doveadm(tlx(a)leuxner.net): Debug: acl: initializing backend with data: vfile:/var/vmail/conf.d/leuxner.net/global-acl:cache_secs=300 doveadm(tlx(a)leuxner.net): Debug: acl: acl username = tlx(a)leuxner.net doveadm(tlx(a)leuxner.net): Debug: acl: owner = 0 doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: Namespace : type=private, prefix=Virtual/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes location=virtual:~/mdbox/virtual doveadm(tlx(a)leuxner.net): Debug: fs: root=/var/vmail/domains/leuxner.net/tlx/mdbox/virtual, index=, indexpvt=, control=, inbox=, alt= doveadm(tlx(a)leuxner.net): Debug: acl: initializing backend with data: vfile:/var/vmail/conf.d/leuxner.net/global-acl:cache_secs=300 doveadm(tlx(a)leuxner.net): Debug: acl: acl username = tlx(a)leuxner.net doveadm(tlx(a)leuxner.net): Debug: acl: owner = 1 doveadm(tlx(a)leuxner.net): Debug: acl vfile: Global ACL file: /var/vmail/conf.d/leuxner.net/global-acl doveadm(tlx(a)leuxner.net): Debug: acl vfile: reading file /var/vmail/public/mailboxes/dovecot-acl doveadm(tlx(a)leuxner.net): Debug: Namespace Public/: /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/2014 doesn't exist yet, using default permissions doveadm(tlx(a)leuxner.net): Debug: Namespace Public/: Using permissions from /var/vmail/public: mode=0700 gid=default doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/dbox-Mails/dovecot-acl not found doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/2014/dbox-Mails/dovecot-acl not found doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/2014/dbox-Mails/dovecot-acl not found doveadm(tlx(a)leuxner.net): Debug: acl vfile: file /var/vmail/public/mailboxes/Archive/Newsletters/heise-security/2014/dbox-Mails/dovecot-acl not found # 2.2.15 (6078354e6238): /etc/dovecot/dovecot.conf I know there have been some changes in Mercurial as to how global ACLs are interpreted. Is doveadm probably behind on them? Regards Thomas

Fetch command response questions
by Vlad Pop 08 Sep '15

08 Sep '15

Hello, I have the following issue: When using command FETCH 2 (BODY.PEEK[HEADER] UID INTERNALDATE FLAGS BODYSTRUCTURE) on 2 different emails, we get 2 different response structure. First response structure contains the BODYSTRUCTURE in a single line, while in the second response, the BODYSTRUCTURE is divided into multiple lines with "{61}" character at the end of each line. The difference between those 2 emails is the name of some attachments. The attachment is an .eml file named "Re: [SR-Users] Keep-Alive in dialog "freeing a free fragment"" Is this a sort of bug or is it correct to receive the BODYSTRUCTURE on multiple lines? Vlad Pop

segfault when using zlib module with glibc 2.22
by Florian Pritz 08 Sep '15

08 Sep '15

Hi, I'm seeing the following segfault when I run `doveadm search mailbox inbox` with the zlib module enabled with dovecot 2.18 and glibc 2.22 on Arch Linux. It does not happen with glibc 2.21. I've noticed that when I remove "zlib" from the mail_plugins line at the beginning of the config file the segfault goes away. I've also tested hg tip and the problem does not appear to be fixed yet. The segfault also happens with other commands like `doveadm purge`. Do you need any more information to reproduce and fix this?

File permissions: system groups for do not work for group/shared mailboxes
by Jens Kirchner 08 Sep '15

08 Sep '15

Hello! I am struggling to set up a group mailbox for users of a certain system group. I want to grant access to the mailbox on a filesystem mode by using the system groups. The problem, the set up works fine and when I use setfacl and grant permissions too each user manually, it works fine. However, I want to use a system user's group membership in order to grant access to these mailboxes insted of manually granting for each user. dovecot version: 2.2.9 This is the config part: namespace { location = maildir:/data/mail/public:LAYOUT=fs prefix = GROUP-MAILBOXES/ separator = / subscriptions = no type = public } ... passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } ... userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } filesystem permissions (getfacl): # file: GroupboxA/ # owner: root # group: root user::rwx user:user1:rwx group::rwx mask::rwx other::--- default:user::rwx default:user:user1:rwx default:group::rwx default:mask::rwx default:other::--- # file: GroupboxB/ # owner: root # group: root user::rwx group::rwx group:group1:rwx mask::rwx other::--- default:user::rwx default:group::rwx default:group:group1:rwx default:mask::rwx default:other::--- user1 is in roup1 When setting username-based permissions (GroupboxA), the mailbox is usable and subsribable; when setting groupname-based permissions (GroupboxB) it is not subscribable/usable. Thanks for your help in advance and best regards, Jens

bug in acl_defaults_from_inbox option
by Marco Giunta 08 Sep '15

08 Sep '15

Hi at all, there is a bug in in acl_defaults_from_inbox option: if you define it with ANY value ('yes', 'no', 'whatyouwant', 'xxx') it acts like the value is ALWAYS 'yes', and Dovecot enable it; the only way to disable it, is comment it or delete from configuration file. With 'acl_defaults_from_inbox = no', or 'acl_defaults_from_inbox = whatyouwant', all my folders get ACLs from INBOX; in my case I want to only share INBOX, but also all other folders were shared. When you comment 'acl_defaults_from_inbox', Dovecot works like expected.

Patch for "doveadm -f table" nit (was Re: Dovecot current number of connections being used.)
by Joseph Tam 08 Sep '15

08 Sep '15

> doveadm who -1 2>/dev/null | wc -l You have to redirect stderr to /dev/null because that's where the first header line is written to. The default format style (table) is inconsistent with the other formats (flow,pager,tab) that write headers and data to stdout. The following patch will pick this nit. This patch will require modifications to scripts that rely on doveadm writing headers to stderr. For example, the above doveadm command could be modified to doveadm who -1 | grep -vc '^username' -------------------------------------------------------------------------------- --- a/dovecot-2.2.16.rc1/src/doveadm/doveadm-print-table.c Wed Mar 18 15:40:40 2015 +++ b/dovecot-2.2.16.rc1/src/doveadm/doveadm-print-table.c Wed Mar 18 15:41:18 2015 @@ -151,3 +151,3 @@ for (i = 0; i < count; i++) { - if (i > 0) fprintf(stderr, " "); + if (i > 0) printf(" "); @@ -155,3 +155,3 @@ DOVEADM_PRINT_HEADER_FLAG_RIGHT_JUSTIFY) == 0) { - fprintf(stderr, "%-*s", (int)headers[i].length, + printf("%-*s", (int)headers[i].length, headers[i].title); @@ -158,3 +158,3 @@ } else { - fprintf(stderr, "%*s", (int)headers[i].length, + printf("%*s", (int)headers[i].length, headers[i].title); @@ -162,3 +162,3 @@ } - fprintf(stderr, "\n"); + printf("\n"); } -------------------------------------------------------------------------------- Joseph Tam <jtam.home(a)gmail.com>
