[Dovecot] bug in dsync
by Tobias Daucher 15 Oct '10

15 Oct '10

Hi, I'm trying to convert mailboxes from mbox zu mdbox. The following command was performed: dsync mirror -u tsdauche mbox:~/.NCmail/Drafts dsync(tsdauche): Fatal: execvp(-u) failed: No such file or directory dsync(tsdauche): Panic: file dsync-worker-local.c: line 185 (dsync_drop_extra_namespaces): assertion failed: (ns != NULL) [1] Abort trap (core dumped) dsync mirror -u tsdauche mbox:~/.NCmail/Drafts I also tried other combinations with dsync, but they all fail... :( I'm sending the core file and the conf output with this mail. Hope you can find out whats the problem, thanks a lot!

[Dovecot] duplicate transaction log sequence?

[Dovecot] Missing ACLOCAL_AMFLAGS ?

[Dovecot] Dovecot chgrp actions on new files/folders
by David Ford 14 Oct '10

14 Oct '10

Timo, I did further study of the user/group permissions. Applying the below patch will make no difference to virtually everyone out there. Those that have default uid/gid ownership won't see any change as the gid already matches so the fchown() action won't be attempted. Those that have sgid will still see the normal expected fchown() enforced by the kernel which becomes a duplicated action by dovecot. In the last case, those with an unknown 3rd party gid were used to seeing fchown() failures and those will now go away. It is only this third group that will see anything change as all other cases are already handled. Anyone who wishes to create new files with another group ID should make their directories sgid or stgid as per normal filesystem ACL semantics. The original net effect of this only turns on an fchown() that will fail and emit numerous error messages. This patch fixes that. Technically the fchown is unneccessary extra code already since any directory that is sgid or stgid will have ownership enforced by the kernel already. I simply made it #if 0 below, the correct patch would be to delete the extraneous block. --- src/lib-storage/mailbox-list.c.orig 2010-09-14 11:03:18.000000000 -0400 +++ src/lib-storage/mailbox-list.c 2010-10-08 13:02:54.000000000 -0400 @@ -450,7 +450,7 @@ } if (S_ISDIR(st.st_mode) && (st.st_mode & S_ISGID) != 0) { - /* directory's GID is used automatically for new + /* directory is sgid, so GID is used automatically for new files */ *gid_r = (gid_t)-1; } else if ((st.st_mode & 0070) >> 3 == (st.st_mode & 0007)) { @@ -460,9 +460,13 @@ } else if (getegid() == st.st_gid) { /* using our own gid, no need to change it */ *gid_r = (gid_t)-1; - } else { + } +#if 0 +#warning this code makes dovecot attempt to chgrp files to wrong ownership + else { *gid_r = st.st_gid; } +#endif } if (name == NULL) {

[Dovecot] lazy_expunge and moving messages
by Lutz Preßler 14 Oct '10

14 Oct '10

Hello, testing the lazy_expunge plugin (with 2.0.5), I realized the following effect, which users may not expect/understand: As moving messages from one folder to another has to be done by clients with the IMAP command sequence COPY STORE EXPUNGE, every moved message is also put into the "shadow folder" of the source folder. Maybe it's possible to extend the plugin to optionally hook into the COPY operation, remember it somewhere with the message (simply as special/ configurable IMAP flag?), and then really expunge messages with this flag set. What do you think? I haven't looked into the plugin interface yet. Of course, if a user manually copies a message and deletes the source message later (maybe having the copy deleted inbetween...), the consequence may not be expected either...

[Dovecot] limits to serve sure a number of users
by Schmidt 14 Oct '10

14 Oct '10

Hi, lets say dovcot should serve 1000 user (only imaps) without rejecting a users connection because of to short resources. With version 1.x I had to increase login_max_processes_count = ... With 2.x I'm not sure which parameters I have to set. So Thunderbird 3.x has a default value of 5 connections to cache. "dovadm who" shows quite often 5 connections: userx 5 imap (11154 11152 11158 11156 11150) ... So dovecot has to be configured for 5000 connections/imap-login's? Within 10-master.conf these defaults are shown #default_process_limit = 100 #default_client_limit = 1000 Is it right process_limit is not generally a problem because oldest imap-login process(?) will be closed? (With this expected number of users this value should be increased too.) But what about client_limit? Does it has to be increased to 5000? (There have been some hints by Timo concerning "doveconf -a service" to see how limits will be used for different services.) Any advices? thanks -- Mit freundlichen Gruessen --- Burckhard Schmidt

[Dovecot] userdb syntax
by suzuki 14 Oct '10

14 Oct '10

Hello, I have a question about userdb lookup when using expire-tool. Dovecot version 1.2.15 In dovecot.conf, mail_location = maildir:/var/mail/%u:INDEX=/var/indexes/%u I run dovecot expire-tool, target user's directory becomes executing user's one. According to wiki, userdb setting overrides mail_location. userdb passwd { mail=maildir:/var/mail/%u:INDEX=/var/indexes/%u } With this setting, it seems working. But, there are no examples with ":INDEX=.." setting. Is this syntax right? Regards

[Dovecot] Problem with dovecot-acl was not solved

Problems with acl in dovecot-1.2.15 was not solved! See my configs below. And I see the new bug - still something wrong with configs: cat dovecot-acl: user=t1 lrwsti #user=oper-olegs lrwsti #user=oper-antona lrwsti user=operdss lr #user=operdss lrwsti User t1 can't create subfolers in inbox. He can only create subfolders in the first levels: Inbox test3 test4 Outbox Sent Trash Test1 - test folder created by t1 user Folders test3 and test4 can't be deleted by t1 - why? Owner of the test3 and test4 - annother user, but but with group rights everething is fine. User operdss also can create folders in the same level with such permissions.
