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

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.

SQL Multiple passwords
by Aubry 19 Aug '24

19 Aug '24

Hi, From what I understood from the archive and from my tests, we cannot have multiple passwords for a given account. (I get the error: Password query returned multiple matches) But it looks like it can be done via a PAM module. Does anyone succeeded setup multiple password with PAM or any other method with a SQL backend ? Regards, Aubry

dovecot-2.3.2.1 and dovecot-pigeonhole-0.5.2 bug?
by Jan Nowak 16 Aug '24

16 Aug '24

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. Configuration: dovecot-2.3.2.1 + dovecot-pigeonhole-0.5.2 + FreeBSD 11.2 log: Sep 06 13:28:17 lda(XXX@XXX)<38615><XXX+XXX>: Info: sieve: msgid=<XXX-XXX-XXX-7788-XXX@XXXXnet>: stored mail into mailbox 'INBOX' Sep 06 13:28:17 lda(XXX@XXX)<38615><XXX+XXX>: Info: sieve: Execution of script /usr/home/XXX/mail/XXX(a)XXX/.dovecot.sieve failed, but implicit keep was successful (user logfile /usr/home/XXX/mail/XXX(a)XXX/.dovecot.sieve.log may reveal additional details) .dovecot.sieve.log: error: msgid=<XXX-XXX-XXX-7788-XXX@XXXXnet>: failed to redirect message to <XXXXX(a)XXXXXX.com>: smtp(127.0.0.1:25): DATA failed: 552 Message header not CRLF terminated (permanent failure). On old configuration: dovecot 2.2 + dovecot-pigeonhole- 0.4 + FreeBSD 11.2 we don't have problem. Has anyone had a similar problem, knows the solution?

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

Strange ssl/dso troubles on freeBSD13.3

02 Aug '24

Hi, I'm George and I think I've been running dovecot for like more than a decade now without any troubles, so: WOW! Nevertheless, after an upgrade from FreeBSD 13.2 to 13.3 plus "pkg upgrade" my dovecot installation refuses to load the ssl certificates. I've tried a version built from source as well as the package. The Problem seems to be something with loading of DSO's: ========================================================================================================= Jul 31 16:42:11 murl dovecot[10801]: imap-login: Error: Failed to initialize SSL server context: Can't load SSL certificate (ssl_cert setting): error:25066067:DSO support routines:dlfcn_load:could not load the shared library: filename(libproviders.so): Shared object "libproviders.so" not found, required by "imap-login", error:25070067:DSO support routines:DSO_load:could not load the shared library, error:0E07506E:configuration file routines:module_load_dso:error loading dso: module=providers, path=providers, error:0E076071:configuration file routines:mo ========================================================================================================= I have never seen 'libproviders' and there's not a lot on it on the internet as well.
