Does anyone know if the use of LMTP (or even the dovecot LDA) still loses the x-original-to header that the postfix vda adds and that I rely heavily on (since I use a lot of aliases), and if it does, is there any solution to get the original recipient added back in before final delivery? Everything I'm reading says that LMTP is better, but I really do need this header (or one like it) to be there so I know who the original recipient was (for filtering and other purposes).

Regression ACL & namespace prefix
by Michal Hlavinka 28 Mar '19

28 Mar '19

Hi tl;dr: Seems that for Global ACL directory, namespace prefix is not part of the path, when looking for acl file. Long version: We're planning to update dovecot in next os update to 2.2.36 and while going through regression testing, we found a problem with ACL configuration combined with namespace. Test uses "Global ACL directory" configuration. Relevant configuration part: mail_location = maildir:~/Maildir namespace inbox { hidden = no inbox = yes list = yes location = prefix = separator = / } namespace { hidden = no list = yes location = maildir:/var/mail/pub prefix = pub/ separator = / type = public } mail_plugins = acl protocol imap { mail_plugins = $mail_plugins acl imap_acl } plugin { acl = vfile:/etc/dovecot/global-acls } ACL config file is stored at: /etc/dovecot/global-acls/pub/.DEFAULT when trying to examine "pub", it is denied: fetchmail: IMAP> A0005 EXAMINE "pub" fetchmail: IMAP< A0005 NO Mailbox doesn't exist: pub (0.001 + 0.000 secs). # doveadm acl debug -u d2 pub doveadm(d2): Info: Mailbox '' is in namespace 'pub/' doveadm(d2): Info: Mailbox path: /var/mail/pub doveadm(d2): Info: All message flags are shared across users in mailbox doveadm(d2): Info: User d2 has no rights for mailbox doveadm(d2): Error: User d2 is missing 'lookup' right doveadm(d2): Info: Mailbox pub is NOT visible in LIST because it did not find acl file: imap(d2): Debug: Namespace : type=public, prefix=pub/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes location=maildir:/var/mail/pub imap(d2): Debug: maildir++: root=/var/mail/pub, index=, indexpvt=, control=, inbox=, alt= imap(d2): Debug: acl: initializing backend with data: vfile:/etc/dovecot/global-acls imap(d2): Debug: acl: acl username = d2 imap(d2): Debug: acl: owner = 0 imap(d2): Debug: acl vfile: Global ACL legacy directory: /etc/dovecot/global-acls imap(d2): Debug: pub: Mailbox opened because: EXAMINE imap(d2): Debug: acl vfile: file /etc/dovecot/global-acls//.DEFAULT not found imap(d2): Debug: acl vfile: file /var/mail/pub/dovecot-acl not found see it's looking for: /etc/dovecot/global-acls//.DEFAULT instead of /etc/dovecot/global-acls/pub/.DEFAULT Checking with documentation https://wiki.dovecot.org/ACL it seems that prefix should still be part of the path, as it was before: """The filenames must start with namespace prefix (if it has one). For example with namespace prefix=INBOX/ containing mailbox "foo" use /etc/dovecot/acls/INBOX/foo.""" Just for comparison, previous version (2.2.10) would work fine: imap(d2): Debug: Namespace : type=public, prefix=pub/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes location=maildir:/var/mail/pub imap(d2): Debug: maildir++: root=/var/mail/pub, index=, indexpvt=, control=, inbox=, alt= imap(d2): Debug: acl: initializing backend with data: vfile:/etc/dovecot/global-acls imap(d2): Debug: acl: acl username = d2 imap(d2): Debug: acl: owner = 0 imap(d2): Debug: acl vfile: Global ACL directory: /etc/dovecot/global-acls imap(d2): Debug: acl vfile: reading file /etc/dovecot/global-acls/pub/.DEFAULT imap(d2): Debug: acl vfile: file /var/mail/pub/dovecot-acl not found I've localized problem to: src/plugins/acl/acl-backend-vfile.c: acl_backend_vfile_object_init(...) and change from: vname = mailbox_list_get_vname(_backend->list, name); to: vname = *name == '\0' ? "" : mailbox_list_get_vname(_backend->list, name); that happened quite time ago during bigger acl changes and I don't know why exactly this line was changed previously. Anyway, reverting this line alone fixes the problem and while testing both per-mailbox ACL vfile and Global ACL file, reverting this did not affect them.

imapsieve: script not triggered
by Andreas Krischer 25 Mar '19

25 Mar '19

Hi, folks! My problem: I set up dovecot with imapsieve to execute a script whenever a user copies a mail to his Spam folder (spam autolearning). Unfortunately this script is never executed regardless what I’m configuring for imapsieve. It looks like dovecot doesn’t really load the plugin… The "dovecot -n" output is attached. I already tried setting imapsieve_mailbox1_name to *, but even this does not execute the script… Also I tried a mailbox without mail_crypt enabled, no success as well. In the attached mail.log (mail_debug=yes) you can see, that imap_sieve_plugin is loaded, but it isn’t really executed. The normal (LMTP) sieve is working - if a mail is incoming the sieve module shows it work in mail.log: May 7 17:54:04 dovecot dovecot: lmtp(postmaster(a)myhost.name): Debug: YEm9ILyS8FqSaAAAujt/SA: sieve: file storage: Storage path `/var/vmail/myhost.name/postmaster/sieve' not found May 7 17:54:04 dovecot dovecot: lmtp(postmaster(a)myhost.name): Debug: YEm9ILyS8FqSaAAAujt/SA: sieve: file storage: Storage path `/var/vmail/myhost.name/postmaster/.dovecot.sieve' not found May 7 17:54:04 dovecot dovecot: lmtp(postmaster(a)myhost.name): Debug: YEm9ILyS8FqSaAAAujt/SA: sieve: storage: No default script location configured May 7 17:54:04 dovecot dovecot: lmtp(postmaster(a)myhost.name): Debug: YEm9ILyS8FqSaAAAujt/SA: sieve: User has no personal script May 7 17:54:04 dovecot dovecot: lmtp(postmaster(a)myhost.name): Debug: YEm9ILyS8FqSaAAAujt/SA: sieve: file storage: Using script storage path: /etc/dovecot/sieve/after/ May 7 17:54:04 dovecot dovecot: lmtp(postmaster(a)myhost.name): Debug: YEm9ILyS8FqSaAAAujt/SA: sieve: file script: Opened script `spam' from `/etc/dovecot/sieve/after/spam.sieve' May 7 17:54:04 dovecot dovecot: lmtp(postmaster(a)myhost.name): Debug: YEm9ILyS8FqSaAAAujt/SA: sieve: executed after user's Sieve script(1): /etc/dovecot/sieve/after/spam.sieve May 7 17:54:04 dovecot dovecot: lmtp(postmaster(a)myhost.name): Debug: Mailbox <lmtp DATA>: Opened mail UID=1 because: header Message-ID (Cache file is unusable) May 7 17:54:04 dovecot dovecot: lmtp(postmaster(a)myhost.name): Debug: YEm9ILyS8FqSaAAAujt/SA: sieve: Opening script 1 of 1 from `/etc/dovecot/sieve/after/spam.sieve' May 7 17:54:04 dovecot dovecot: lmtp(postmaster(a)myhost.name): Debug: YEm9ILyS8FqSaAAAujt/SA: sieve: Loading script /etc/dovecot/sieve/after/spam.sieve May 7 17:54:04 dovecot dovecot: lmtp(postmaster(a)myhost.name): Debug: YEm9ILyS8FqSaAAAujt/SA: sieve: Script binary /etc/dovecot/sieve/after/spam.svbin successfully loaded May 7 17:54:04 dovecot dovecot: lmtp(postmaster(a)myhost.name): Debug: YEm9ILyS8FqSaAAAujt/SA: sieve: binary save: not saving binary /etc/dovecot/sieve/after/spam.svbin, because it is already stored May 7 17:54:04 dovecot dovecot: lmtp(postmaster(a)myhost.name): Debug: YEm9ILyS8FqSaAAAujt/SA: sieve: Executing script from `/etc/dovecot/sieve/after/spam.svbin' I already spent hours on this problem so please let me know if you have any idea what the problem could be… :( Thanks in advance!

Inbox quota usage doubled when mailbox_list_index enabled, under some circumstances
by Chris Dillon 13 Mar '19

13 Mar '19

Hello, I searched through the list archives for anything that appeared to be similar to this but I didn't find any good matches. I apologize if this has been brought up before. Beginning with Dovecot 2.2.34, reported quota usage of a user's inbox can be doubled when the following criteria are met: 1) quota plugin is enabled 2) mailbox_list_index=yes 3) A sub-folder of the inbox exists whose name also matches the prefix (for example, "INBOX.Test"), even if that folder has no contents. (Apparently, some mail clients such as K-9 Mail on Android can create these folders automatically) Downgrading to 2.2.33.2 allows this configuration to work normally. I looked through the changes in git between 2.2.33.2 and 2.2.34 and they appeared extensive, so unfortunately I wasn't able to pinpoint a specific change that caused this. Reproduced on a CentOS 7 server with Dovecot 2.2.34 built from git sources according to https://wiki2.dovecot.org/CompilingSource#Compiling_Dovecot_From_Git using the following minimal configuration: ========== root@centos7 [~]# dovecot -n # 2.2.34 (874deae): /usr/local/etc/dovecot/dovecot.conf # OS: Linux 3.10.0-862.9.1.el7.x86_64 x86_64 CentOS Linux release 7.5.1804 (Core) # Hostname: centos7.local mail_location = maildir:~/Maildir mail_plugins = quota mailbox_list_index = yes namespace inbox { inbox = yes location = prefix = INBOX. separator = . } passdb { driver = pam } plugin { quota = maildir:Mailbox } userdb { driver = passwd } ========== With the system user "myuser" and a minimal Maildir setup containing 1 email in the inbox, and one sub-folder named "INBOX.Test": ========== root@centos7 [~]# ls -lAR /home/myuser/Maildir /home/myuser/Maildir: total 4 drwxr-xr-x. 2 myuser myuser 77 Jul 25 09:36 cur drwxr-xr-x. 5 myuser myuser 56 Jul 25 15:19 .INBOX.Test -rw-r--r--. 1 myuser myuser 14 Jul 25 15:19 maildirsize drwxr-xr-x. 2 myuser myuser 6 Jul 25 09:36 new drwxr-xr-x. 2 myuser myuser 6 Jul 25 09:36 tmp /home/myuser/Maildir/cur: total 12416 -rw-r--r--. 1 myuser myuser 12712627 Jul 25 09:07 1532529376.M543965P58007.centos7.local,S=12712627,W=12877782:2,S /home/myuser/Maildir/.INBOX.Test: total 0 drwxr-xr-x. 2 myuser myuser 6 Jul 25 09:36 cur -rw-r--r--. 1 myuser myuser 0 Jul 25 09:36 maildirfolder drwxr-xr-x. 2 myuser myuser 6 Jul 25 09:36 new drwxr-xr-x. 2 myuser myuser 6 Jul 25 09:36 tmp /home/myuser/Maildir/.INBOX.Test/cur: total 0 /home/myuser/Maildir/.INBOX.Test/new: total 0 /home/myuser/Maildir/.INBOX.Test/tmp: total 0 /home/myuser/Maildir/new: total 0 /home/myuser/Maildir/tmp: total 0 ========== Given this configuration, when "mailbox_list_index" is enabled, after quota recalculation, quota reports that there are 2 messages and that double the amount of storage is used: ========== root@centos7 [~]# doveadm quota recalc -u myuser; doveadm quota get -u myuser Quota name Type Value Limit % Mailbox STORAGE 24830 - 0 Mailbox MESSAGE 2 - 0 ========== When "mailbox_list_index" is disabled and quota is recalculated, it will report the message and storage counts correctly: ========== root@centos7 [~]# doveadm -o 'mailbox_list_index=no' quota recalc -u myuser; doveadm quota get -u myuser Quota name Type Value Limit % Mailbox STORAGE 12415 - 0 Mailbox MESSAGE 1 - 0 ========== I am hoping that someone with much more familiarity with the code path involved here could take a look at this issue and possibly submit a fix for it -- that would be greatly appreciated. Please let me know if you need any more details regarding the replication steps, though I hope that I didn't miss anything.

SELinux policy to allow Dovecot to connect to Mysql
by Robert Moskowitz 05 Feb '19

05 Feb '19

As I have noted in previous messages, I been getting the following on my new mailserver: Apr 7 10:17:27 z9m9z dovecot: dict: Error: mysql(localhost): Connect failed to database (postfix): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (13) - waiting for 25 seconds before retry They go away when I setenforce 0. It is not a timing issue as I earlier thought. So I googled dovecot mysql selinux and the only worthwhile hit was: http://zszsit.blogspot.com/2012/12/dovecot-mysql-selinux-issue-on-centos6.h… that provides a /etc/selinux/dovecot2mysql.te and other selinux stuff. Is there a simpler way like a setsbool option? With all the howtos on dovecot with mysql, it is interesting that none of them seem to have this problem. Maybe because they connect to mysql through TCP port 3306 which has ITS set of problems (like MariaDB defaults to not listening on TCP). thanks!

auth: Error - Request timed out
by Hajo Locke 01 Feb '19

01 Feb '19

Hello List, i use dovecot 2.2.22 and have the same problem described here: https://dovecot.org/pipermail/dovecot/2017-November/110020.html I can confirm that sometimes there is a problem with connection to mysql-db, but sometimes not. Reasons for failing are still under investigation by my mates. My current main problem is, that this fail seems to be a one way ticket for dovecot. Even if mysql is verifyable working again and waiting for connection dovecot stucks furthermore with errors like this: May 29 07:00:49 hostname dovecot: auth: Error: plain(mail(a)example.com,xxx.xxx.xx.xxx,<HGI4FVFt2Oy80j3P>): Request 999.7 timed out after 150 secs, state=1 When restarting dovecot all is immediately working again. Is there a way to tell dovecot to restart auth services or reinitialize mysql-connection after these hard fails? I could insert "idle_kill = 1 mins" into service auth and service auth-worker, but i dont know if this would work. Unfortunately i am not able to reproduce this error and there are always a couple of days between errors. Thanks, Hajo

Dovecot Submission Proxy Auth
by Paul Hecker 12 Jan '19

12 Jan '19

Hi, Dovecot 2.3.1 (8e2f634). Could not get Dovecot to forward the (plain) authentication to the SMTP server using submission. Reason why I need it is sender spoofing (do not want my employees to send messages in behalf of me). In exim I can disable sender spoofing with the authenticated user. When sending through dovecot, exim either does not accept the email (need auth) or relay every sender address (because relaying from localhost). Am I missing a setting or do I need any additional field in the (MySQL) user_query/password_query to forward the password? You can find my config here: https://gist.github.com/lluuaapp/7daddf761131da47237b0f45e6bab5a8 Thanks, Paul
