vacation auto reply mail line endings CR LF

Hi all, I tried to setup dovecot 2.3.21.1 (d492236fa0) (dovecot-pigeonhole-0.5.21.1) with the sieve vacation function. I'm getting here a bit into trouble. if I sent an e-mail to an receipient dovecot does via dma and the local mailserver an mail reply but the mail does only have the header inside. After a bit research my conclusion is that the reply mail which gets generated has line endings CR LF. I have to remove this manualy and set it to \LF to get the mail correcly transfered. I Setup the sieve rule with roundcube. I tried to manualy change the .dovecot.sieve file endings and comipled with sievec .dovecot.sieve .dovecot.svbin the binary again, with no change in the behavior. I guess i missed somewhere an variable to fix this issue? here the sieve file: #################################################### require ["vacation"];^M # rule:[Urlaub]^M if true^M {^M vacation :addresses "test02(a)projektb-mail.net" :subject "test Urlaub" text:^M test 1 test 2 test 3^M .^M ;^M }^M #################################################### thank you for your Support Tobias

What is the best way to get rid of this message? I think clients start generating after ssl crt update.

ACL propagation with acl_defaults_from_inbox
by Francois Lesueur 19 Dec '24

19 Dec '24

Hello, When dovecot is configured with "acl_defaults_from_inbox = yes", ACL propagation when creating folders seems a bit strange to us. The current behavior is : - INBOX has some ACLs defined in its dovecot-acl file - This ACL is the default for subfolders without a dovecot-acl file inside ("acl_defaults_from_inbox = yes") - When creating a folder, a dovecot-acl file is created inside this folder with a copy of the contents of the dovecot-acl from the INBOX The behavior we expected was : - INBOX has some ACLs defined in its dovecot-acl file - This ACL is the default for subfolders without a dovecot-acl file inside - When creating a folder directly under INBOX, a dovecot-acl file should not be created, as the default from INBOX is already enforced. For subfolders, defaults from INBOX should not be propagated either in the dovecot-acl files. Although dovecot-acl files in subfolders allow to have exceptions, most usage of "acl_defaults_from_inbox = yes" is probably to have mailbox-wide ACLs. In the current behavior, when someone removes an ACL from the INBOX, it will still be present in subfolders, which is error-prone in a setup where users expect that their INBOX ACL is enforced throughout their mailbox. I think that avoiding propagating INBOX ACL when creating a new folder in the case where "acl_defaults_from_inbox" is activated would be more intuitive. Am I missing something ? Cheers, Francois

Recursive doveadm acl add for shared mailbox
by r.barclay＠habmalnefrage.de 17 Dec '24

17 Dec '24

Hello, I have a shared mailbox (e.g. "info(a)example.org") and want to give a new user (e.g. "john.doe(a)example.org") access. I can use: doveadm acl add -u info(a)example.org INBOX user=john.doe(a)example.org create delete expunge insert lookup post read write write-deleted write-seen Unfortunately, the shared mailbox contains several nested folders. And the new user needs to access these, too. So I probably had to use doveadm acl add -u info(a)example.org .INBOX.SubfolderXY user=john.doe(a)example.org create delete expunge insert lookup post read write write-deleted write-seen ... for each and every subfolder. Is there a way to give permissions recursively? INBOX and all (sub-)subfolders? And, by the way, do I have to use doveadm acl recalc -u info(a)example.org OR doveadm acl recalc -u john.doe(a)example.org after that? At the moment I always do both. Thank you! Reg

dovecot configuration question userdb driver
by Stanislav 17 Dec '24

17 Dec '24

Greetings, I have a mail server for a few folks, basically my family. My current Dovecot configuration is the following, which works like a charm: ========== passdb { driver = sql args = /usr/local/etc/dovecot/dovecot-sql.conf.ext } userdb { driver = static args = uid=981 gid=981 home=/var/mail/virtual/%d/%n/home } ========== I've decided to deploy Solr to be able to search faster. Now, when I try to execute "doveadm index -A inbox" I get an error "Error: auth-master: userdb list: User listing returned failure" because I'm using the static userdb. My question is, how do I implement the listing users feature while using "static driver" or a similar approach? I really want to keep using the template "/var/mail/virtual/%d/%n/home" instead of defining a custom path for each user. So I came up with this idea to replace "static" with "sql" driver for "userdb" since there's "iterate_query" I can use to achieve my goal, tho I have to define "user_query", so I can do something like: ======= SELECT '/var/mail/virtual/%d/%n/home' AS maildir, 981 AS uid, 981 AS gid FROM mailbox WHERE username='%u' and active='1'; ======= However, this is a useless waste of resources since I'm not really querying anything, and I'm not even sure if there's template support (e.g., %d/%n) in there. Appreciate any help Best

Error: Couldn't open INBOX: Permission denied
by dovecot＠crighton.me.uk 15 Dec '24

I'm trying to get Dovecot working on Rocky 9.5. In 10-mail.conf I have: mail_privileged_group = mail mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u In /var/spool: drwxr-x---. 3 mail mail 64 Dec 13 16:29 mail In /var/spool/mail: -rw-rw----. 1 peter mail 500 Dec 13 16:29 peter When I try to login using Telnet I get the following in /var/log/maillog: Dec 13 17:03:23 Backup dovecot[690594]: pop3-login: Login: user=<peter>, method=PLAIN, rip=172.21.10.5, lip=172.21.10.5, mpid=690664, secured, session=<8Or5zikp7uCsFQoF> Dec 13 17:03:23 Backup dovecot[690594]: pop3(peter)<690664><>: Error: Couldn't open INBOX: Permission denied Dec 13 17:03:23 Backup dovecot[690594]: pop3(peter)<690664><>: Disconnected: Couldn't open INBOX: Permission denied top=0/0, retr=0/0, del=0/0, size=0 (There is a random data between <> - I've deleted it as I'm not sure if it is sensitive. I'm certain I'm typing the password correctly in Telnet and I think the first of the three lines from the log indicate that I successfully connected. But why do I get Permission denied when Dovecot tries to open the INBOX? As far as I can see I've set them right (as per the permissions pasted above).

Rebuild uuidlist?
by Gandalf Corvotempesta 14 Dec '24

14 Dec '24

Guys i did a mess. A bad script made by me, changed (a lot) of filenames in the maildir, in example almost all email filenames were changed. I think I have to rebuild the UID <> filename mapping because dovecot is still trying to read the old file that doesn't exists anymore (it has a new name) Any suggestions? I think this would lead to a full-download of all messages client side, right ?
