dsync migration from maildir layout=fs to maildir seperator / - folders or inbox but not both
by Matt Bryant 13 May '18

13 May '18

Am attempting to bring my mailserver back to home server post house move and whilst I could use rsync have been trying to get to grips with dsync. However, I seem to have an issue - my current server specifies mail_location as maildir:/var/vmail/%d/%n/Maildir:LAYOUT=fs and my imapc config on new server is as follows ... imapc_host = old.mailserver.host imapc_user = %u imapc_master_user = master imapc_password = ********** imapc_features = $imapc_features rfc822.size fetch-headers imapc_list_prefix = INBOX imapc_port = 993 imapc_ssl = imaps imapc_ssl_verify = no the trouble is if I leave imapc_list_prefix = INBOX I get the inbox only - no folders ... If I comment this out delete maildir on target and re-run .. I get the folders but no inbox but folders are in fs layout format rather than being converted to INBOX.folder.subfolder bug perhaps ???? or am I doing something wrong ??? src dovecot version 2.0.9 tgt dovecot version 2.2.33.2 Any ideas would be appreciated ... rgds Matt -- <https://www.postbox-inc.com/?utm_source=email&utm_medium=siglink&utm_campai…>

Marks as read on mover to Archive
by ＠lbutlr 13 May '18

13 May '18

How would I setup dovecot so that when messages are moved to the Archive mailbox, they are marked as read? Would it be similar to the imap-sieve for spam tagging? imapsieve_mailbox1_name = Junk imapsieve_mailbox1_causes = COPY imapsieve_mailbox1_before = file:/usr/lib/dovecot/sieve/report-spam.sieve Or is there a simpler method? If it matters: mailbox Archive { auto = subscribe special_use = \Archive -- According to the philosopher Ly Tin Weedle, chaos is found in greatest abundance wherever order is being sought. It always defeats order, because it is better organized.

Dovecot 2.2.36-rc1 and $HasAttachment
by Alessio Cecchi 10 May '18

10 May '18

Hi, I installed dovecot 2.2.36-rc1 and enabled: mail_attachment_detection_options = add-flags-on-save but when messages are delivery via dovecot-lda into mailbox (Maildir) keywords are not added. Only when the messages is open keywords ($HasAttachment or $HasNoAttachment) are added. From the wiki "attachments are detected and marked during save", delivery via LDA is "save"? For info, doveadm rebuild attachments works fine. Since 2.2.36 will be the last v2.2.x release I hope that this feature will be fixed since is very useful.

mmap failed messages in syslog
by Shawn Heisey 10 May '18

10 May '18

I'm getting mmap failed messages in syslog on version 1.2.15 for dovecot.index.cache files. This old dovecot version is installed with debian packages. The OS and all software is 64-bit. I've found info on this log message, with a suggested fix of raising vsz_limit ... but this seems to be a config option for dovecot 2.x, not 1.x. The file it complains about being unable to mmap is only 90MB, and the biggest cache file I have found on the system is only 180MB. The system has 4GB of total memory with about 1GB of that allocated to OS disk cache right now. The mmap functionality provided by the OS doesn't use *actual* memory, so the amount of memory I have should be irrelevant. Checking 'ulimit -a' with several users shows that vmemory is unlimited for all of them. How do I go about allowing docevot 1.x to use more virtual memory? I do have a migration planned to Ubuntu 16, where I can run a 2.x version, but that's not going to happen for a while. Thanks, Shawn

Hi, I'm trying to use this expression in Sieve, but for some reason the filter doesn't work: require ["fileinto","regex"]; # rule:[gmail-outlook-yahoo-aol-friends] if header :regex "received" ".from.*(outbound.protection.outlook.com|.google.com|.yahoo.com|mx.aol.com)." { fileinto "INBOX.gmail-hotmail-yahoo-aol-friends"; stop; } However, it's working fine with egrep: egrep ".from.*(outbound.protection.outlook.com|.google.com|.yahoo.com|mx.aol.com)." * 1525657297.M401428P1459.host01.quick.net.au,S=10073,W=10275:2,S:Received: from APC01-PU1-obe.outbound.protection.outlook.com (mail-oln040092254061.outbound.protection.outlook.com [40.92.254.61]) Am I using Sieve correctly here? Is ".from.*(outbound.protection.outlook.com|.google.com|.yahoo.com|mx.aol.com)." expression valid for Sieve? Or do I have to split it in an array as per https://wiki2.dovecot.org/Pigeonhole/Sieve/Examples#Flagging_or_Highlightin… example? Thanks, -- Adi Pircalabu

Released Pigeonhole v0.4.24.rc1 for Dovecot v2.2.36.rc1.

Hello Dovecot users, Here's a first release candidate for the upcoming Pigeonhole release for Dovecot v2.2.36. It only contains bugfixes for now. There's one experimental plugin still in the pipeline. Changelog v0.4.24: - Fix assert panics triggered by empty messages that are being forwarded using redirect or vnd.dovecot.report. This does not likely normally occur, but this is seen as a result of certain benign failures in object storage. - Make the length of the subject header for the vacation response configurable and enforce the limit in UTF-8 codepoints rather than bytes. The subject header for a vacation response was statically truncated to 256 bytes, which is too limited for multi-byte UTF-8 characters. - Sieve editheader extension: Fix assertion panic occurring when it is used to manipulate a message header with a very large header field. - Properly abort execution of the sieve_discard script upon error. Before, the LDA Sieve plugin attempted to execute the sieve_discard script when an error occurs. This can lead to the message being lost. - Fix the interaction between quota and the sieve_discard script. When quota was used together with a sieve_discard script, the message delivery did not bounce when the quota was exceeded. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.24… http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.24… Refer to http://pigeonhole.dovecot.org and the Dovecot wiki for more information. Have fun testing this release candidate and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl
