BUG: dsync and folder names with "@"
by spamvoll＠googlemail.com 20 Feb '20

20 Feb '20

Hello, dovecot version: 2.3.9.2 When I use dsync: /usr/bin/dsync -v -D -o plugin/quota= -f -u my(a)email.dom backup maildir:/tmp/mailbackup/Maildir it always stops when it comes to a folder with an "@" in its name. Error Message: Warning: Mailbox changes caused a desync. You may want to run dsync again: Remote lost mailbox GUID (maybe it was just deleted?) I dont know if it makes a difference, but my dovecot uses mdbox and the backup export is maildir. Hans

RE: Unknown setting error with dovecot-sql.conf.ext

OMG, that was it, so sorry to have wasted your time. The text editor I am using (Ultraedit) is adding a BOM (Byte Order Marker) to the beginning of the file. I have disabled this in settings but it keeps doing it. Thank you so much for pointing me in the right direction. After removing the 3 invisible characters from the dovecot-sql.conf.ext file it magically worked.

Flush userdb cache entry
by Tom Sommer 19 Feb '20

19 Feb '20

Hi all I have a problem when users change quota in SQL, the change is not reflected in Dovecot immediately so quota_warning is still triggered on some occasions. I think it's because the quota is stored in userdb, and there is no way to flush userdb cache? Is there a way to flush userdb entries? What controls userdb cache TTL/size? auth_cache entries? I can't seem to find any documentation on this, sadly :( Thanks -- Tom

Message-id parsing by sieve
by Russell King 19 Feb '20

19 Feb '20

Hi, I'm using Dovecot for my mail with pigeonhole's sieve extension, from debian stable (2.3.4.1 (f79e8e7e4)). One of the sieve stanzas that I use is for duplicate elimination: if duplicate { discard; stop; } This mostly works fine, but I seem to have trouble with some messages that come from certain domains where duplicates are not eliminated. >From /var/log/mail.log, I see: Feb 18 12:48:50 mail dovecot: lmtp(24320:linux@xxx.armlinux.org.uk): sieve: msgid=? <VI1PR04MB513558BF77192255CBE12102B0110(a)VI1PR04MB5135.eurprd04.prod.outlook.com>: stored mail into mailbox 'INBOX' Feb 18 12:49:42 mail dovecot: lmtp(24320:linux@xxx.armlinux.org.uk): sieve: msgid=<VI1PR04MB513558BF77192255CBE12102B0110(a)VI1PR04MB5135.eurprd04.prod.outlook.com>: stored mail into mailbox 'INBOX' The first was received direct from the recipient with a message-id line formatted thusly: Message-ID: <VI1PR04MB513558BF77192255CBE12102B0110(a)VI1PR04MB5135.eurprd04.prod.outlook.com> The second was received from the mailing list with a message-id line formatted thusly: Message-ID: <VI1PR04MB513558BF77192255CBE12102B0110(a)VI1PR04MB5135.eurprd04.prod.outlook.com> It would appear that the parsed message-id value that dovecot uses includes white-space (including newline characters). RFC5322 gives the message-id header format as: message-id = "Message-ID:" msg-id CRLF msg-id = [CFWS] "<" id-left "@" id-right ">" [CFWS] It goes on to say: The message identifier (msg-id) itself MUST be a globally unique identifier for a message. and: Semantically, the angle bracket characters are not part of the msg-id; the msg-id is what is contained between the two angle bracket characters. However, it seems dovecot sieve is using the entire content of the msg-id, including CFWS, as the message id used for detecting duplicate messages. This seems wrong, and appears to lead to duplicates not being detected, and thus seems like a bug. Is there a workaround for this, and/or can it be changed? -- Russell King

Sieve junks mail script creating links
by ＠lbutlr 19 Feb '20

19 Feb '20

My Junk mailbox is still filling up with hard linked emails. There are some junk mails with over 3000 hard linked files and over half a million files in the .Junk/cur folder. I had a handy script to remove them all by doing a find for inodes and sorting the list by age and keeping the olds hard link and removing all the others, but I now can’t find it :/ so I have just taken to periodically nuking the entire folder, but I’d like to fix this. *everything is current on FreeBSD 12.1-RELEASE => dovecot.conf imapsieve_mailbox1_before = file:/usr/lib/dovecot/sieve/report-spam.sieve => /usr/lib/dovecot/sieve/report-spam.sieve: require ["vnd.dovecot.pipe", "copy", "imapsieve", "environment", "variables"]; if environment :matches "imap.user" "*" { set "username" "${1}"; } pipe :copy "sa-learn-spam.sh" [ "${username}" ]; => /usr/lib/dovecot/sieve/sa-learn-spam.sh: #!/bin/sh exec /usr/local/bin/sa-learn -u ${1} —spam -- When the stars threw down their spears And watered heaven with their tears, Did He smile his work to see?

managesieve / sieve - append dot prefix on moving mails into folder
by Andre Hoepner - i.based: Systemhaus GmbH + Co. KG 18 Feb '20

18 Feb '20

Hello mailinglist-subscribers, i have an issue with the managesieve / sieve plugin in dovecot. We use roundcube as webmailer and if i define a new filter to move incoming mails directly into a subfolder i get the following sieve-code: require ["fileinto","imap4flags"]; # rule:[mail into folder] if allof (header :contains "from" "sender(a)domain.org") { fileinto "Foldername"; setflag "\\Seen"; } So anything seems to be right and there are no errors on creating the correct syntax. But if a mail comes from the named sender, sieve does not put the email in the folder "Foldername" but ".Foldername". It appends a dot (.) in front of the name and i have no idea, why this happens. There are no errors in logfile and all mails go into the .Folder. Maybe it is wrong separator for mailbox, at the moment there is no separator defined in "10-mail.conf" and we use "Maildir" as mail_location. I have also tried to change the target folder in sieve script an named him "INBOX/Monitoring" - as subfolder of INBOX but than i get an error in .dovecot.sieve.log with message: Invalid mailbox name: Name must not have '/' characters. I edited the new rule with roundcube / managesieve-plugin and maybe this needs separate configuration because of separator in foldernames? Please let me know if i should provide any extra information or dovecot configuration etc. best regards Andre Hoepner

Postfix Dovecot Consultant Availability
by Asai 17 Feb '20

17 Feb '20

Greetings, We're in process of upgrading our Postfix / Dovecot installation, and would like to know if there are any qualified consultants out there that would be willing to work for us to help us verify and improve the deployment for our non-profit organization? This would be a fairly simple job of looking over configs and making recommendations, but may give way into more ongoing work. I know there are a lot of experts on this list that really know how Postfix and Dovecot work and we'd really appreciate some quality advice. I'm sending this request to both Postfix and Dovecot lists. Please email me directly with replies. -- Asai

Sieve setting a flag on the server (with sieve?)
by Marc Roos 17 Feb '20

17 Feb '20

I want to run a cron job for specific users. I thought the easiest would be a sieve plugin that sets some text in managesieve.sieve. And I just have my cron job check for this setting. This is the forward sieve: if false # true { redirect :copy "test(a)test.com"; } So maybe something like: if false # true { # cronjob1 } Or is there a better way of doing such a thing?
