sieve vacation to an alias group
by Monis Monther 13 Mar '19

13 Mar '19

Hi, We have an alias group named xyz(a)example.com, this alias group has 3 actual users a(a)example.com, b(a)example.com and c(a)example.com We set vacation rule on the generic sieve rule, the problem is that 3 responses are sent to the original sender. (obviously because the rule is being executed with each user in the alias group) Is it possible to set auto response only once, we tried the ( :days 1) option but still all 3 respond back. How can such a setup be achieved. (Single auto response to an alias group) CentOS 7.5 dovecot-pigeonhole-2.3.4.1-1.x86_64 dovecot-2.3.4.1-1.x86_64 postfix 2.10-1 -- Best Regards Monis

Delayed flags changes over IDLE
by Kostya Vasilyev 13 Mar '19

13 Mar '19

Hello, I'm experiencing slow flags changes over IMAP IDLE: - If I start an IDLE session / command - Change the flags of some messages via another email app - Dovecot can take a minute or more to notify the IDLE connection about flags changes If I use another email app to add or remove a message, Dovecot sends that (EXISTS / EXPUNGE) instantly and also flushes the (so far delayed) flags changes. So it does "know" already. The system is Debian Testing, 64 bit, file system is ext4. Dovecot is 2.3.4.1 (f79e8e7e4) - I believe from Debian repos (I had Dovecot's own repo added at some point, disabled now). My mail is stored under ~/mail/.imap (not sure what this format is called), I mean not "single file mbox". I have not changed any IDLE related config settings: doveconf | grep -i idle default_idle_kill = 1 mins director_ping_idle_timeout = 30 secs imap_idle_notify_interval = 2 mins imapc_max_idle_time = 29 mins mailbox_idle_check_interval = 30 secs What can I do to make Dovecot notify IDLE clients about flags changes - more quickly? Preferably near-instant? -- Kostya Vasilyev kman(a)fastmail.com

“doveadm mailbox” command fails with UTF-8 mailboxes
by Felipe Gasper 13 Mar '19

13 Mar '19

Hello, I’ve got a strange misconfiguration where the following command: doveadm -f pager mailbox status -u spamutf8 'messages vsize guid' INBOX 'INBOX.*' … fails with error code 68, saying that it can’t find one of the mailboxes. (It lists the user’s other mailboxes.) The name of the mailbox in question is saved to disk in UTF-8 rather than mUTF-7, but strace shows that doveadm is stat()ing the mUTF-7 path; the failure of that stat() is, assumedly, what causes doveadm to report the error status. I’ve tried to paw through the source code to see what might be causing this but haven’t made much headway. Can someone here point out where the misconfiguration might be that is causing doveadm to stat() the mUTF-7 path rather than UTF-8? Or perhaps offer any tips as to how I might diagnose what’s going on? What causes doveadm to stat() one path or the other? Thank you! -Felipe Gasper Mississauga, ON

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.

After removing "starttls=y" from the static passdb entry, the mail is sent successfully. Starting with version 2.3.2 the lmtp proxy uses starttls as well, therefore the error seems to be there. I've not been able to figure out, if this has to do with the content of the mails, because they are from many different sources. Thanks! Marcus

Hi everyone! I’m using dovecot 2.3.5. submission-login is crashing many times in a day: Here is a sample error message: dovecot: submission-login: Fatal: master: service(submission-login): child 34247 killed with signal 11 (core not dumped - https://dovecot.org/bugreport.html#coredumps - set service submission-login { drop_priv_before_exec=yes }) After I added drop_priv_before_exec, I got these error messages: submission-login: Error: master-service: cannot get filters: net_connect_unix(/var/run/dovecot/config) failed: Permission denied dovecot: master: Error: service(submission-login): command startup failed, throttling for 2 secs How to get submission core dumps properly? Thank you. — Marcelo Coelho

imap-hibernate not working
by Marcelo Coelho 13 Mar '19

Hi, I follow different setup instructions and I can't make imap-hibernate work. I've tried vmail and dovecot as users, tried to set mode to 0666, without success. I'm using FreeBSD 11.2. Is imap-hibernate compatible with FreeBSD 11.2? My operational system: # uname -v FreeBSD 11.2-RELEASE-p9 #0: Tue Feb 5 15:30:36 UTC 2019 root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC Here are my logs: Mar 8 15:30:57 servername dovecot: imap(user@domain.com:52.125.128.90): Error: kevent(-1) for notify remove failed: Bad file descriptor Mar 8 15:30:57 servername dovecot: imap(user@domain.com:52.125.128.90): Error: close(-1) for notify remove failed: Bad file descriptor Mar 8 15:30:57 servername dovecot: imap-hibernate: Error: Failed to parse client input: Invalid peer_dev_minor value: 18446744073709486335 Mar 8 15:30:57 servername dovecot: imap(user@domain.com:52.125.128.90): Error: /opt/dovecot/2.3.5/var/run/dovecot/imap-hibernate returned failure: Failed to parse client input: Invalid peer_dev_minor value: 18446744073709486335 Mar 8 15:30:57 servername dovecot: imap: Error: Here are my processes: # ps aux | grep imap dovenull 68264 0.0 0.0 12012 8292 -
