Namespace for seperate Storage of Archive
by Christian Großegger 05 Oct '24

05 Oct '24

Hi everyone, I found the Solution myself. The key was to simply create an unnamed mailbox directive so that the namespace prefix directly results into an mailbox that Thunderbirds shows as the Archive. Thanks everbody on the dovecot team for making such a brilliant Software! Greetings! Christian namespace inbox { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = / } namespace archivns { prefix = Archive/ <--- this is the Name which now appears at the same Level then Sent/Draft/... location = maildir:/mnt/mails2/%u separator = / mailbox { <--- here a name is omitted auto = subscribe special_use = \Archive } }

Namespace for seperate Storage of Archive
by Christian Großegger 30 Sep '24

30 Sep '24

Hi everyone, I would like to move the "Archives" Folder for every user from my default storage to another storage in the backend, while maintaining the current frontend view of the IMAP Mailboxstructure. Because I didn't manage to get it to work properly on my production server, I made a separate Testserver. My problem is, that I don't know what to put in the "prefix" section of the Namespace, so that the Archive Folder is on the same folder/mailbox hierarchy level as the ones in the default namespace (Sent Messages, Drafts ...). I have read the Namespace RFC (rfc2342) and there is one example which uses the Tilde ~ Character as the Namespace prefix - put the rfc doesn't address the tilde, it only has it in one of the examples (Example 5.4). Because ~ often means 'base folder' I thought this would work. But it doesn't. The Thunderbird client shows: Rootdir/Sent but Rootdir/~/Archive I am aware I can solve this with symlinks, but I would like to do it properly with namespaces. Could you please tell me what I am missing? In case this is an Thunderbird Issue, could you please point out, what I don't understand? Thank you!

last_login plugin does not update IP
by Maciej Polewczyński 30 Sep '24

30 Sep '24

When using the last_login plugin I noticed that the IP address information is not updated. If there is no entry in the sql database for a given user, the first time the login date and time information and the IP address will be saved. Each subsequent login only updates the date and time. The IP address remains unchanged. Example configuration for pop3 service: map { pattern = shared/last-login/pop3/$user/$rip table = last_login value_field = last_pop3_access value_type = uint fields { userid = $user last_pop3_ip = $rip } } This is translated into the following sql command: INSERT INTO last_login (last_pop3_access,userid,last_pop3_ip) VALUES (1727691183673,'test','1.2.3.4') ON DUPLICATE KEY UPDATE last_pop3_access=1727691183673 You can see that after "ON DUPLICATE KEY" only the time is updated. Is there any way to influence the behavior of the plugin and the sql query so that the IP address is also updated? I'm using Dovecot v2.3.4 -- Best regards, Maciej Polewczyński Do or do not. There is no try.

Remove hard-coded paths in doc/solr-config-9.xml
by Saman Ghannadzadeh 30 Sep '24

30 Sep '24

Hi, Dovecote includes a config file for use with Solr 9, at 'doc/solr-config-9.xml'. However, this file has two problems: - it hard codes the path to the Solr installation - it hard codes version numbers of Icu/Lucene packages This issue can be be easily fixed by using the '${solr.install.dir}' variable in that config file. The attached patch will fix both issues. Best wishes, Saman Ghannadzaded diff -crB a/doc/solr-config-9.xml b/doc/solr-config-9.xml *** a/doc/solr-config-9.xml 2024-09-29 20:50:42.873229769 +0100 --- b/doc/solr-config-9.xml 2024-09-29 20:58:53.507638810 +0100 *************** *** 75,82 ****   ! <lib dir="/opt/solr/modules/analysis-extras/lib" regex="icu4j-70.1.jar"/> ! <lib dir="/opt/solr/modules/analysis-extras/lib" regex="lucene-analysis-icu-9.8.0.jar"/>   ! <lib dir="${solr.install.dir}/modules/analysis-extras/lib" regex="icu4j-.*\.jar"/> ! <lib dir="${solr.install.dir}/modules/analysis-extras/lib" regex="lucene-analysis-icu-.*\.jar"/> <!-- an exact 'path' can be used instead of a 'dir' to specify a specific jar file.

Dovecot trying to fetch a directory that contains a typo, couldn't figure out where to fix it
by Yassine Chaouche 29 Sep '24

29 Sep '24

Dear list, I am encountering an unusual issue where Thunderbird is incorrectly accessing my "Messagerie" folder. While there are no visible errors within Thunderbird, Dovecot logs reveal several permission-denied messages linked to the folder structure. Sep 29 16:45:20 imap(a.chaouche(a)domain.tld): Debug: acl vfile: file /var/vmail/domain.tld/a.chaouche/dovecot/../.Messagerie/dovecot-acl not found Sep 29 16:45:20 imap(a.chaouche(a)domain.tld): Error: open(/var/vmail/domain.tld/a.chaouche/dovecot/../.Messagerie/cur/-Tlevel=matching) failed: Permission denied (euid=1001(vmail) egid=1001(vmail) missing +r perm: /var/vmail/a lgerian-radio.dz/a.chaouche/dovecot/../.Messagerie/cur/-Tlevel=matching) Sep 29 16:45:20 imap(a.chaouche(a)domain.tld): Error: open(/var/vmail/domain.tld/a.chaouche/dovecot/../.Messagerie/cur/-Tlevel=matching) failed: Permission denied (euid=1001(vmail) egid=1001(vmail) missing +r perm: /var/vmail/a lgerian-radio.dz/a.chaouche/dovecot/../.Messagerie/cur/-Tlevel=matching) Sep 29 16:45:20 imap(a.chaouche(a)domain.tld): Info: Disconnected: Internal error occurred.

What is the appropriate action for out of memory error for exceeding vsz_limit in my situation?
by Steve Dondley 29 Sep '24

29 Sep '24

Hi, I have sporadic messages on my server about an account getting an out of memory error: Fatal: master: service(imap): child 17910 returned error 83 (Out of memory (service imap { vsz_limit=325 MB }, you may need to increase it) - set CORE_OUTOFMEM=1 environment to get core dump) In response, I raised the limit from 256MB up to 325. That didn’t seem to help. The server has only 512 MB of RAM so I’m afraid to go much higher. I googled around a bit and some people are saying that when the dovecot.index.cache grows too large, it can cause these errors. The imap account has a dovecot.index.cache file that is 167 MB which seems to be well below the limit (but maybe it is compressed?). So I’m not entirely sure as to what the underlying problem is. So before upgrading to the server to 1024 MB of ram and going on a wild goose chase, I just want to get input on whether I have positively identified the problem and whether there might be something else I can do to manage this problem.

TLS certificates SQL driver ?
by Andrew Mason 28 Sep '24

28 Sep '24

Hi folks, I was curious if it was possible to configure Dovecot to lookup the TLS certificate it should present in a similar way that the passdb lookups can use a driver. I have a few domains that share the same IP and I'm currently using SNI with both Dovecot and Postfix. I have pretty much all the configuration stored for each domain in a relational database , including the TLS cert that Postfix presents. If I add a new domain, I still have to add an entry to config file for dovecot i.e local_name imap.example.org { ssl_cert = </etc/ssl/certs/imap.example.org.crt ssl_key = </etc/ssl/private/imap.example.org.key } local_name imap.example2.org { ssl_cert = </etc/ssl/certs/imap.example2.org.crt ssl_key = </etc/ssl/private/imap.example2.org.key } I was hoping it was possible to use the same records in the database that I currently use for Postfix. Kind regards Andrew

Dovecot undeleteable folder?
by Benoît Panizzon 27 Sep '24

27 Sep '24

Hi Liste We are and ISP and use Dovecot. From time to time, we have customer reporting not being able to delete IMAP folder they have created. This often seems to happen when some email client is creating temporary folder on some move or copy operations. Permissions look right. I can't figure out, what goes wrong, but I can reproduce via telnet by manually issuing IMAP commands. To me it looks like Dovecot forgets about what folders exist. Is there some caching of the folder information? Is there a way to enable some debug logging of folder creation and deletion? Example: Customer has a Folder named: ARCHIV.AdministrationXXX Folder file exists and permissions look right: ./ARCHIV/AdministrationXXX d delete ARCHIV.AdministrationXXX d OK Delete completed (0.001 + 0.000 secs). Folder file is still present and can not be deleted again. Re-Connecting with a client lists the folder as present despite having been deleted. It's sort of a Schrödinger Folder. It is there but it's also not there. c create ARCHIV.AdministrationXXX c OK Create completed (0.007 + 0.000 + 0.006 secs). d delete ARCHIV.AdministrationXXX d OK Delete completed (0.006 + 0.000 + 0.005 secs). Now the Folder File is gone, showing the permissions were correct. I can do this corrective action via telnet. But most mail clients will refuse to create a Folder with the same name as an existing one. What could cause that issue and how I could try to further debug the issue? No errors, no hints in the logs. -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

hello I encountered the following issue while compiling Dovecot on a Linux system with the Shenwei architecture in China using RPM: During the build phase, it shows: Copy Code checking whether fd passing works... no configure: error: fd passing is required for Dovecot to work The version of Dovecot I am compiling is 2.3.16, and the version of the GCC tool is 8.5.0.

dsync with vurtial folder leads to mess of msg ID
by Kirill A. Korinsky 25 Sep '24

25 Sep '24

Greetings, I have a setup with two dovecot servers and dsync replication between them. On both of them I have a virtual folders, forexample All with config: mx1# cat /etc/dovecot/virtual/All/dovecot-virtual * -Trash -Trash/* -Junk -Junk/* all All virtual folders are excluded from replication because it leads to broken replication with errors like: virtual.All can't be created. So, I have. replication_dsync_parameters = -d -l 30 -U -x virtual. Unfortently, after a couple of weeks I've noticed that msg id for the same message on the different servers aren't match. For example: mx1# doveadm fetch -u kirill(a)korins.ky 'uid' mailbox virtual.All header Message-ID 'macports/macports-ports/pull/22284/c1901369454(a)github.com' uid: 157786 mx1# doveadm fetch -u kirill(a)korins.ky 'uid' mailbox INBOX header Message-ID 'macports/macports-ports/pull/22284/c1901369454(a)github.com' uid: 5561 mx1# vs mx2# doveadm fetch -u kirill(a)korins.ky 'uid' mailbox virtual.All header Message-ID 'macports/macports-ports/pull/22284/c1901369454(a)github.com' uid: 157766 mx2# doveadm fetch -u kirill(a)korins.ky 'uid' mailbox INBOX header Message-ID 'macports/macports-ports/pull/22284/c1901369454(a)github.com' uid: 5561 mx2# as you may see msgid at INBOX are matched, but it isn't true for virtual.All, here 157786 vs 157766 So, here the question: how can I sync msg id inside virtual folder on this setup? -- wbr, Kirill
