dsync with vurtial folder leads to mess of msg ID
by Kirill A. Korinsky 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

Hi, I've seen a few emails over the years related to this error message, but they are typically associated with doveadm. In my case, it's related to dovecot itself. I've just set up dovecot-2.3.20-1.fc37.x86_64 on fedora37 and unable to receive mail. The main config was copied over from another dovecot system on fedora37 with virtually identical settings, including the same SSL cert. I've also tried to just migrate the important stuff and otherwise leave the defaults, but I'm having the same problem. imap(bcc-user)<2977522><rappeBf6vLZEw8Eq>: Debug: Loading modules from directory: /usr/lib64/dovecot imap(bcc-user)<2977522><rappeBf6vLZEw8Eq>: Debug: Module loaded: /usr/lib64/dovecot/lib20_listescape_plugin.so imap(bcc-user)<2977522><rappeBf6vLZEw8Eq>: Debug: Effective uid=1001, gid=1001, home=/home/bcc-user imap(bcc-user)<2977522><rappeBf6vLZEw8Eq>: Debug: open(/proc/self/io) failed: Permission denied imap(bcc-user)<2977522><rappeBf6vLZEw8Eq>: Debug: Namespace inbox: type=private, prefix=, sep=, inbox=yes, hidden=no, list=yes, subscriptions=yes location=mbox:~/mail:INBOX=/var/spool/mail/bcc-user imap(bcc-user)<2977522><rappeBf6vLZEw8Eq>: Debug: fs: root=/home/bcc-user/mail, index=, indexpvt=, control=, inbox=/var/spool/mail/bcc-user, alt= imap(bcc-user)<2977522><rappeBf6vLZEw8Eq>: Debug: Mailbox Trash: Mailbox opened I've set the /var/spool/mail/bcc-user permissions to 600, bcc-user:mail.

dovecot-2.3.2.1 and dovecot-pigeonhole-0.5.2 bug?

Hello, we have a problem after updating the software with the operation of sieve scripts sending a copy of the e-mails, e-mails are not transferred.

The future of SIS
by Sebastian Marsching 16 Aug '24

16 Aug '24

Hi, I am currently in the process of planning a new deployment of Dovecot. I was planning to use mdbox or sdbox with “mail_attachment_fs = sis posix”, but I stumbled across the following notice in the documentation for Dovecot 3.0 (https://doc.dovecot.org/3.0/settings/core/#core_setting-mail_attachment_fs) > Changed in version 2.4.0 (CE): SIS is deprecated and writing of SIS files is disabled. Reading is supported for now, any missing SIS attachments are replaced with files filled with spaces. > > Changed in version 3.0.0 (Pro): SIS is deprecated and writing of SIS files is disabled. Reading is supported for now, any missing SIS attachments are replaced with files filled with spaces. And https://doc.dovecot.org/3.0/installation_guide/upgrading/from-2.3-to-3.0/ says: > Saving new mails’ attachments via fs-sis is disabled, but reading SIS attachments is still supported. Missing SIS attachments are replaced with files filled with spaces. What is not entirely clear from this comment is whether this only applied to “sis posix” or also to “sis-queue posix”. Does anybody whether sis-queue is also affected by this? I saw that the notice was added to the dovecot/documentation Git repository in April 2023, but I couldn’t find any further information there or the main branch of the dovecot/core repository. Maybe, the code for 2.4 / 3.0 has not made it into that branch or repository yet. SIS sounds like a neat concept and I would like to use it, but obviously I do not want to use a soon-to-be-deprecated feature in a completely new deployment. So, does anybody know an alternative solution for attachment deduplication (except file-system level deduplication)? Thanks, Sebastian

dictionary with %d variable in sql stops insert and select domain part - dovecot 2.3.17+
by Mariusz Piasecki 16 Jul '24

16 Jul '24

Hi, I notice that quota domain when using args %d in dictionary isn't honored in mysql during updates and selects when using dovecot 2.3.17+, so I moved my tests to docker environment, because I started using alpine linux and thought it could be musl library problem. I tested few versions with debian/alpine and after 2.3.17 updates and selects for domain in sql not using domain part, but user@domain. Maybe I missed some changes in configuration, maybe someone experience this behavior? User in logs was changed to h.user(a)example.com. Configuration as described in documentation quota = dict:<quota root name>:<username>[:<option>[...]]:<dictionary URI> where username could be %d for supporting domain-wide quotas quota =

using dovecot 2.3.17+, so I moved my tests to docker environment, because I started using alpine linux and thought it could be musl library problem. I tested few versions with debian/alpine and after 2.3.17 updates and selects for domain in sql not using domain part, but user@domain. Maybe I missed some changes in configuration, maybe someone experience this behavior? User in logs was changed to h.user(a)example.com. ***** Configuration ***** as described in documentation quota = dict:<quota root name>:<username>[: <option>[...]]:<dictionary URI> where username could be %d for supporting domain-wide quotas quota = dict:user_quota::proxy::sqluserquota quota2 = dict:domain_quota:%d:proxy::sqldomainquota dict { acl = mysql:/etc/dovecot/dovecot-share-folder.conf sqldomainquota = mysql:/etc/dovecot/dovecot-dict-sql-domain.conf sqluserquota = mysql:/etc/dovecot/dovecot-dict-sql-user.conf } dovecot-dict-sql-domain.conf map { pattern = priv/quota/storage table = used_domain_quota username_field = domain value_field = bytes } map { pattern = priv/quota/messages table = used_domain_quota username_field = domain value_field = messages } dovecot-dict-sql-user.conf map { pattern = priv/quota/storage table = used_quota username_field = username value_field = bytes } map { pattern = priv/quota/messages table = used_quota username_field = username value_field = messages } Example dump sql table, in real environment with newer dovecot, there was only h.user(a)example.com and no domain record.

[auth] epoll_ctl(add, 13) failed: Operation not permitted (fd doesn't support epoll)
by Alexander Vogt 05 Jul '24

Hi all, dovecot auth service is failing when using an inet_service. The configuration is essentially: service auth { inet_listener { address = * port = 12345 } unix_listener auth-userdb { group = vmail mode = 0666 user = vmail } } When I connect to port 12345 (real IMAP client or telnet doesn't make a difference), the auth service crashes.

doveadm backup has problems with some accounts

I try to setup for our mailserver (in a dc) a job backup to a secondary server (in our office) with "doveadm backup" via the -R option. (rsync , rsnapshot and so on tooks too long at the moment) For the most user accounts all work as expected, but for three users it always fails First run: /usr/bin/doveadm -Dv backup -Ru user1 tcp:mua01.domain.intra:12345 > Dec 01 08:54:21 doveadm(user1)<70126><qfzHDjyfaWXuEQEAy5X8iQ>: Debug: Mailbox INBOX: Mailbox opened because: copy caching decisions > Dec 01 08:54:22 doveadm(user1)<70126><qfzHDjyfaWXuEQEAy5X8iQ>: Warning: Deleting mailbox 'Archiv.Allgemein unsortiert': UID=1 GUID=1350559209.P2052Q54.lin-mail1.intra is missing locally > Dec 01 08:54:22 doveadm(user1)<70126><qfzHDjyfaWXuEQEAy5X8iQ>: Debug: brain M: Import Archiv.Allgemein unsortiert: Import change type=save GUID=1350559209.P2052Q54.mail1.intra UID=1 > hdr_hash= result=Reverting local change by deleting mailbox - No more local mails found > Dec 01 08:54:22 doveadm(70126): Debug: brain M: Import Archiv.Allgemein unsortiert: Saved UIDs: > Dec 01 08:54:22 doveadm(70126): Debug: auth-master: conn unix:/run/dovecot/auth-userdb (pid=661,uid=0): Disconnected: Connection closed (fd=9) So it aborts on the lines above and a incomplete maildir is on the local server. so the next doveadm try say's that he can't delete INBOX , etc. > Dec 01 09:03:33 doveadm(user1)<70169><TzH+MmKhaWUZEgEAy5X8iQ>: Error: Mailbox INBOX sync: mailbox_delete failed: INBOX can't be deleted. This a very old account on our server which was migrated over different iterations of our dovecot mailserver. The user behind the account uses outlook over years. Is the space here a problem? Another user with a similiar issue has the following error message at the end: > Dec 01 09:22:14 doveadm(user2)<70354><RU12FsWlaWXSEgEAy5X8iQ>: Debug: Mailbox INBOX: Mailbox opened because: copy caching decisions > Dec 01 09:22:56 doveadm(user2)<70354><RU12FsWlaWXSEgEAy5X8iQ>: Error: read(mua01.domain.intra) failed: EOF (last sent=mailbox, last recv=mailbox) > Dec 01 09:22:56 doveadm(70354): Debug: auth-master: conn unix:/run/dovecot/auth-userdb (pid=661,uid=0): Disconnected: Connection closed (fd=9) I see that the user has a very big inbox? when i check in the source server in the "cur" folder of the INBOX it count's around 269372 mails. Is this perhaps the issue for this message? And on the last user it looks like: Dec 01 09:25:19 doveadm(user3)<70376><UoiQAHWmaWXoEgEAy5X8iQ>: Warning: Deleting mailbox 'Entwürfe': UID=1265 GUID=1521832311.M6830P7652.mail-mx1.intra,S=1764,W=1809 is missing locally Dec 01 09:25:19 doveadm(user3)<70376><UoiQAHWmaWXoEgEAy5X8iQ>: Debug: brain M: Import Entwürfe: Import change type=save GUID=1521832311.M6830P7652.mail-mx1.intra,S=1764,W=1809 UID=1265 hdr_hash= result=Reverting local change by deleting mailbox - No more local mails found Dec 01 09:25:19 doveadm(70376): Debug: brain M: Import Entwürfe: Saved UIDs: Dec 01 09:25:19 doveadm(70376): Debug: auth-master: conn unix:/run/dovecot/auth-userdb (pid=661,uid=0): Disconnected: Connection closed (fd=9) The "Entwürfe" folder directly cannot be the issue? On the filesystem the folder has the name ".Entw&APw-rfe" and also other users has similar folders in their mailboxes. The source server has dovecot version 2.2.36 (centos 7.9.2009) and the current destination server dovecot version 2.3.16 (ubuntu 22.04 lts)
