Hello, dovecot --version 2.3.17 (e2aa53df5b) debug log: Debug: duplicate db: transaction: Too many duplicate IDs locked Debug: duplicate db: transaction: Check ID: too many IDs locked - .sieve with 100+ redirects ( 201 actually ) #define DUPLICATE_LOCK_MAX_LOCKS 100 It's not corresponding with sieve_max_redirects = 310 or sieve_max_actions = 320 On dovecot 2.3.16 version DUPLICATE_LOCK_MAX_LOCKS is not implemented and redirects work correctly. Thank you. Vladimir Gulas.

app-specific passwords for dovecot
by mj 08 Dec '21

08 Dec '21

Hi all, I have read these documents on the subject of app-specific passwords: > https://www.dgsiegel.net/news/2013_05_21-application_specific_passwords_for… > https://www.happyassassin.net/posts/2014/08/26/adding-application-specific-… But since both articles are rather old, I'd like to ask if there are other/new ways of implementing app-specific passwords for dovecot/imap and postfix/smtp. Also perhaps (web?) GUI's exist, to make it possible for the users themselves to generate/edit those passwords..? Thanks for your suggestions! MJ

vsz_limit
by Daniel Miller 07 Dec '21

07 Dec '21

I just noticed, that when checking "doveconf -a" - all vsz_limit settings that are not explicitly given have a value of: 18446744073709551615 B I have this on two servers, one with an implicit default_vsz_limit=256M, the other with an explicit default_vsz_limit=2G. Is this correct? -- Daniel

I've run dovecot-sysreport -o <core> and generated a file - but it's a few gigs in size. Am I generating the core dump incorrectly? Should I do something different? -- Daniel

LDAP and user duplicated with replication
by Claudio Corvino 07 Dec '21

07 Dec '21

Hi, I have two IMAP/LMTP Dovecot server in replica (version 2.3.4.1), I use LDAP/AD for /userdb, /replica is working. When I do a search like: /doveadm replicator status '*'/ I receive user duplicated, with and without the domain part, for example: /test/ /test(a)domain.com/ but they are the same user; this lead the replicator doing twice the work of replication. I think this is related to //etc/dovecot/dovecot-ldap.conf/ that is configured in this way: /hosts = xxx/ /base = dc=xxx,dc=xxx ldap_version=3 auth_bind = yes dn = cn=xxx,cn=Users,dc=xxx,dc=xxx dnpass = xxx scope = subtree user_attrs = sAMAccountName=home=/mnt/mail-storage-lv0007/%$,=uid=501,=gid=501 pass_attrs = sAMAccountName=user user_filter = (&(objectclass=person)(samaccountname=%n)) pass_filter= (&(objectclass=person)(samaccountname=%n)) iterate_attrs = sAMAccountName=user # With following filter we exclude all objects without an email address, all computers and all inactive accounts / /iterate_filter = (&(objectCategory=person)(mail=*)(objectClass=user)(!(userAccountControl:1.2.840.113556.1.4.803:=2))) / I think that *iterate_attrs* and *iterate_filter* should be fixed, but I don't know how/./ Please could someone give me any hints? Thanks/ / Regards/ /

public folders, ACLs
by Stefan G. Weichinger 06 Dec '21

06 Dec '21

greetings ... I got the following request from a customer where we run dovecot-2.3.15 on a debian server: They have a public folder with all their project-related subfolders inside: namespace { location = maildir:/home/vmail/oeffentlich prefix = Oeffentlich/ separator = / subscriptions = yes type = public } So far we don't have the mail_plugin ACL enabled. They want to be able to create projectfolders that aren't move/delete/rename-able by the users, only by some admins. But the users should be allowed to move mails between different projectfolders etc As far as I understand we can do that with Dovecot ACLs (although I am still figuring out how to properly design them ...). My questions: * if I enable the mail_plugin for ACLs, does that in any way change the behavior of existing mailboxes? afai understand: no. Only if ACL-lists exist in the various mailboxes, these get applied, right? I don't want to break things, and I want to avoid additional complexity for the non-public user mailboxes etc Maybe I can enable the plugin only for that public namespace? * maybe someone has a link to a similar setup? thanks in advance, Stefan

Re[5]: Replication weirdness
by Daniel Miller - CLOUD 04 Dec '21

04 Dec '21

Another update. I dug deeper into the mailboxes - and found the "subscriptions" and actual mailboxes weren't correct in all cases. I guess when I shifted to the explicit INBOX/ namespace not all the existing boxes migrated correctly. So...after manually correcting all the "subscription" files, and manually moving the duplicated "Archives" folders to the correct locations nearly all the errors have gone. I wish I'd gotten more inforrmative error messages, and processes certainly shouldn't have crashed, but since I obviously created the problem due to manually poking things and improper configuration I guess I can't complain too much. I still have problems using the "-N" flag for syncing - but things seem to be working with the multiple explicit "-n" namespaces. I do still have the locking error appearing during long-running syncs - I don't see why Dovecot doesn't know that it's already syncing a given user before trying to start a second process. Probably something else I setup wrong but I don't know what. -- Daniel
