Probleme with replication and shared mailbox
by Laurent BRAULT (OSILOG) 06 Mar '19

06 Mar '19

Hi Folks ! I finaly resolve my problem ! 😊 First of all I had to modify namespaces : ####################################################### namespace inbox { inbox = yes location = mailbox Archive { auto = subscribe special_use = \Archive } mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = INBOX/ separator = / subscriptions = yes type = private } namespace partage { list = children location = maildir:/mnt/mail/vmail/%%d/%%n:INDEXPVT=/mnt/mail/vmail/%d/%n/shared/%%u prefix = shared/%%u/ separator = / subscriptions = yes type = shared } ####################################################### Also change the « replication_dsync_parameters » in aim to syncronize only the Private namespace : ==> replication_dsync_parameters = -d -n inbox -l 30 -U I change the sharing command from « acl set » to « acl add » AND THE MOST IMPORTANT ==> RUN THE COMMAND ON THE 2 SERVER because of active/active réplication… ==> doveadm acl add -u user2(a)exemple.fr INBOX user=user1(a)exemple.fr admin create delete expunge insert lookup post read write write-deleted write-seen Hope this may help if someone is faced to the same problem Best regards Laurent

“Message cannot be displayed because of the way it is formatted” iOS
by James Brown 06 Mar '19

06 Mar '19

Have updated our mail server and are now running Dovecot 2.3.4. Things are mostly working OK, but occasionally I have users on latest iOS getting this message: “this message cannot be displayed because of the way it is formatted. Ask the sender to send it again using a different format or email program. multipart/alternative” The email seems to open OK on the macOS version of Mail.app. Also getting “Loading...” displayed in body section of the app with content never displayed. Most emails are fine, but just get this strange ones occasionally. Our previous mail server was much older, with older version of Dovecot, etc. This server never used to have these issues. Just wondering if anyone has any ideas or suggestions? Can’t see anything in the logs. Thanks, James.

getrandom() before forking daemon is blocking init system
by Axel Burri 05 Mar '19

05 Mar '19

Hello When booting from a slow machine, I can observe dovecot blocking the whole boot process. I traced it down to the getrandom() system call in lib/randgen.c, which blocks until the random number generator is initialized (dmesg "random: crng init done"). This can take up to three minutes (!) on my machine, as there is not much entropy available (no hardware RNG, network VPN is also waiting for random). Unfortunately dovecot calls getrandom() before forking a daemon, which as a consequence blocks the whole init process (OpenRC on Gentoo Linux). I believe this behavior has changed in kernel 4.14: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=… Quoting getrandom(2): "If the urandom source has not yet been initialized, then getrandom() will block, unless GRND_NONBLOCK is specified in flags." Dovecot: 2.3.4.1 (f79e8e7e4) Linux: 4.19.26-gentoo #2 SMP Thu Feb 28 20:30:23 CET 2019 x86_64 AMD G-T40E Processor AuthenticAMD GNU/Linux Regards, Axel

Pigeonhole v0.5.5 released
by Aki Tuomi 05 Mar '19

05 Mar '19

Hi! We are happy to release pigeonhole v0.5.5 for dovecot v2.3.5. Please find sources at https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.5.ta… https://pigeonhole.dovecot.org/releases/2.3/dovecot-2.3-pigeonhole-0.5.5.ta… (Please note that the signing key has been changed for 0.5.5, see https://pigeonhole.dovecot.org/download.html for details.) You can find precompiled binaries at https://repo.dovecot.org/ NEWS: + IMAPSieve: Add new plugin/imapsieve_expunge_discarded setting which causes messages discarded by an IMAPSieve script to be expunged immediately, rather than only being marked as "\Deleted" (which is still the default behavior). - IMAPSieve: Fix panic crash occurring when a COPY command copies messages from a virtual mailbox where the source messages originate from more than a single real mailbox. - imap4flags extension: Fix deleting all keywords. When the action resulted in all keywords being removed, no changes were actually applied. - variables extension: Fix truncation of UTF-8 variable content. The maximum size of Sieve variables was enforced by truncating the variable string content bluntly at the limit, but this does not consider UTF-8 code point boundaries. This resulted in broken UTF-8 strings. This problem also surfaced for variable modifiers, such as the ":encodeurl" modifier provided by the Sieve "enotify" extension. In that case, the resulting URI escaping could also be truncated inappropriately. - IMAPSieve, IMAP FILTER=SIEVE: Fix replacing a modified message. Sieve scripts running in IMAPSIEVE or IMAP FILTER=SIEVE context that modify the message, stored the message a second time, rather than replacing the originally stored unmodified message. - Fix segmentation fault occurring when both the sieve_extprograms plugin (for the Sieve interpreter) and the imap_filter_sieve plugin (for IMAP) are loaded at the same time. A symbol was defined by both plugins, causing a clash when both were loaded. --- Aki Tuomi Open-Xchange Oy

two lots of dovecot files
by mick crane 04 Mar '19

04 Mar '19

hello is debian buster I have 2 sets of dovecot files, I don't know why. one in /etc/dovecot and one in /usr/share/dovecot they are not links they are actual files. if I rename /etc/dovecot and restart service then I get connection refused when use roundcube. Some time ago my roundcube installation stopped working properly for the web configuration options. Should I have these 2 directories or just want the one ? If want only one it's likely then that I configure wrong file with same name when I thought my ssl certificate has expired. Is OK to delete /etc/dovecot and check configuration in /usr/share/dovecot ? -- Key ID C7D6E24C

Pigeonhome Sieve: check existence of a folder?
by AvV 03 Mar '19

03 Mar '19

Dear All, Thanks ofr the great job so far. I have crawled the doc & web, and did not find oh to check for the presence of a folder ina a mailbox? I know about "fileinto :create" of course, but the purpose is slightly different: I want to automate the move into a folder based on some rules but *only if* an associated folder is present (which name is based on the rule), otherwise I will do a form of catch-all. Example: - INBOX +- abc +- def - Rule detects "aaa" in someheader field: folder "aaa" not present" -> continue; - Rule detect "def" in some header field: "def exists" -> fileinto "def" ; stop; Any help appreciated. Cheers, A/
