[Dovecot] IMAP Folder permissions
by Stuart Gall 07 Jan '09

07 Jan '09

Hello, Happy new year. I have a dovecot with exim installation. I am using virtual users for mail and IMAP. When dovecot creates a folder from imap user the permissions are rwx------ I need them to be rwxrwx--- Is there a way to change this in the configuration file ?

[Dovecot] writing a dovecot plugin / segfault
by Stefan Jurisch 07 Jan '09

07 Jan '09

Hi together, I am new to this list and new to dovecot itself. I have to write a plugin that implements some ACL-voodoo to be used instead of the standard ACL stuff of dovecot (it shall allow just application-driven folder-sharing - no more, no less). Though I started programming with C, my last experiences are some days old, but now I have written the function sekeletons and the registration function with the 'register-command"-calls etc. The makefile-stuff I copied from the imap-quota-plugin and modified it, so all appearances of "lib11_imap_quota_plugin..." and similar are now found as "lib11_folderacl_plugin..." and so on. In short words: I think I have done all nessessary mods to the source (I tried it some days ago with a slightly older version of dovecot, and until I did some unknown thing, it worked quite well...) to make the whole thing work. One example function is (just testing at the moment): /* MYRIGHTS <folder>: retreive the rights of the current folder */ static bool cmd_myrights(struct client_command_context *cmd) { struct mail_storage *storage; struct mailbox *folder; const char *folder_name; string_t *response; /* read argument: <folder> */ if (!client_read_string_args(cmd, 1, &folder_name)) return FALSE; /* work done from here... */ /* for the moment, do a dummy response */ str_append(response, "* MYRIGHTS "); str_append(response, folder_name); str_append(response, " lrswipcda"); client_send_line(cmd->client, str_c(response)); client_send_tagline(cmd, "OK Completed."); return TRUE; } But when testing via "telnet localhost 143" and doing a "20 myrights INBOX" the imap thread just crashes and does not give any answer. in /var/log/messages I only find something like the following entry: Jan 5 13:40:12 kungfu kernel: imap[8991]: segfault at 4 ip 080d5c67 sp bf82b040 error 4 in imap[8048000+b8000] Maybe somebody can tell me, what this is? If needed, I also post the complete code itself somewhere. Thanks in advance.

[Dovecot] mbox "Next message unexpectedly lost" bug fixed
by Timo Sirainen 06 Jan '09

06 Jan '09

Good news, everyone! The most annoying bug in v1.1 series should finally be fixed by these patches: http://hg.dovecot.org/dovecot-1.1/rev/f28348c5201e http://hg.dovecot.org/dovecot-1.1/rev/74c47fcfb420 http://hg.dovecot.org/dovecot-1.1/rev/a28520d26b5a http://hg.dovecot.org/dovecot-1.1/rev/539f8d983285 http://hg.dovecot.org/dovecot-1.1/rev/9b7af230f9f0 They also make sure that mbox is never read while it's not locked. I think that could have happened in some situations with v1.1. Hopefully mbox handling will now finally be as stable in v1.1 as it was in v1.0. I'll make a new v1.1 release after seeing what bug fixes are coming from Apple, so probably next week.

[Dovecot] New SSL certificate problem
by Stewart Dean 05 Jan '09

05 Jan '09

Our DC has been using a Verisign certificate. Over the past year, we've been using a Digicert Wildcard Plus certificate for almost all of our machines, and I wanted to switched over our DC mailserver. I used the following command to generate the CSR and key: openssl req -new -newkey rsa:1024 -nodes -out star_bard_edu.csr -keyout star_bard_edu.key -subj "/C=US/ST=NY/L=ourtown/O=Bard College IT/OU=Bard College /CN=*.bard.edu" The resultant CSR verified and I submitted it to digicert and got back our cert, plus their intermediate and Trusted root certs. I killed the root instance of dovecot and waited for all the children to die I put together the intermediate cert (first) and our cert (second) into /usr/ssl/certs/dovecot.pem I put the key star_bard_edu.key in /var/ssl/private/dovecot.pem I restarted dovecot, but the imap login instances didn't appear, so I shifted back to the original combined cert file and key, restarted dovecot and it came up OK I check the syslog and saw these error messages: Jan 5 10:19:49 mercury mail:err|error dovecot: imap-login: Can't load private k ey file /var/ssl/private/dovecot.pem: error:0B080074:x509 certificate routines:X 509_check_private_key:key values mismatch Jan 5 10:19:49 mercury mail:err|error last message repeated 8 times Jan 5 10:19:49 mercury mail:err|error dovecot: child 4051108 (login) returned e rror 89 Jan 5 10:19:49 mercury mail:err|error dovecot: child 4231382 (login) returned e rror 89 I checked my key and it has the same time stamp as my CSR, so I didn't somehow get the wrong key. Both the old and new key are 600; if the old one works based on perms, the new one should too. Would some kind soul tell me what I'm missing? Or is there a problem using wild card certificate with DC? Is there an openssl command to verify the key. Or is it that the key is unencrypted? -- ==== Once upon a time, the Internet was a friendly, neighbors-helping-neighbors small town, and no one locked their doors.

[Dovecot] Permission to distribute Dovecot run file
by Rick Widmer 04 Jan '09

04 Jan '09

I am working on updating the Shupp toaster, http://shupp.org/toaster/ a set of files and instructions for installing qmail, vpopmail, qmailadmin and squirrelmail. Two of my most important goals are switching the imap program from courier to Dovecot, and closer integration with OpenSuSE. (Which I run my mail servers on.) To follow the style of the toaster I need a place where I can obtain the init.d script from http://wiki.dovecot.org/DovecotInit I would prefer to have permission to host the file myself so I don't have to worry about creating patches if there is ever a need for my run file to be different from yours. If that is not acceptable, would you please either provide a URL where I can download just the run file, or include it in the distribution. Thanks, Rick

[Dovecot] Warnings compiling on OpenBSD 4.4 i386
by Peter Lindgren 04 Jan '09

04 Jan '09

Hi, probably just nothing to worry about, but I get the following warnings when building 1.1.7 on OpenBSD 4.4 on i386. If I remove the --with-bsdauth config option, they all disappear. I won't use it anyway, but maybe there are others. $ dmesg OpenBSD 4.4 (GENERIC) #1021: Tue Aug 12 17:16:55 MDT 2008 deraadt@i386.openbsd.org:/usr/src/sys/arch/i386/compile/GENERIC cpu0: Intel(R) Xeon(R) CPU 3040 @ 1.86GHz ("GenuineIntel" 686-class) 1.87 GHz cpu0: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,SBF,SSE3,MWAIT,DS-CPL,VMX,EST,TM2,CX16,xTPR real mem = 1071788032 (1022MB) avail mem = 1027936256 (980MB) mainbus0 at root bios0 at mainbus0: AT/286+ BIOS, date 12/31/99, BIOS32 rev. 0 @ 0xfd460, SMBIOS rev. 2.4 @ 0xdc010 (48 entries) bios0: vendor HP version "O10" date 07/20/2007 bios0: HP ProLiant ML110 G4 $ ./configure --without-pop3d --with-deliver --with-passwd --with-passwd-file --with-bsdauth --without-ldap --sysconfdir=/etc --localstatedir=/var --sharedstatedir=/var mail-index-map.c: In function `mail_index_map_ext_hdr_check': mail-index-map.c:171: warning: comparison between signed and unsigned mail-index-map.c: In function `mail_index_map_clone': mail-index-map.c:1112: warning: comparison between signed and unsigned mail-index-sync-update.c: In function `sync_header_update': mail-index-sync-update.c:419: warning: comparison between signed and unsigned mail-transaction-log-file.c: In function `log_file_track_mailbox_sync_offset_hdr': mail-transaction-log-file.c:682: warning: comparison between signed and unsigned passdb-bsdauth.c: In function `bsdauth_preinit': passdb-bsdauth.c:59: warning: implicit declaration of function `auth_cache_parse_key' passdb-bsdauth.c:60: warning: assignment makes pointer from integer without a cast /Peter -- Peter Lindgren http://www.norrskenkonsult.com

[Dovecot] convert non-standard mbox to maildir
by Maarten Bezemer 03 Jan '09

03 Jan '09

Hi, Let me start with wishing you all the best for this new year, and I hope we'll see a lot of new features and not so much new bugs ;-) I'm trying to convert a number of PSTs to maildir. Just plain drag&drop in Outlook doesn't work (gives a very cryptic error message in a certain folder, but that folder is perfectly all right), and using the import option also barfs when it's not even half-way through the PST. So, I took aid4mail and it converted the PST to mbox wihtout any problem. But now, I have a directory structure, filled with mbox mailboxes. Like: INBOX INBOX/mailbox INBOX/subfolder INBOX/subfolder/mailbox INBOX/subfolder/subsubfolder INBOX/subfolder/subsubfolder/mailbox INBOX/subfolder2 INBOX/subfolder2/mailbox etc. This differs from normal mbox setup, but given the fact that there are both folders AND messages below inbox, this is indeed the only useful way to do it. But now I cannot convert this to maildir using either dovecot or mb2md, since it's not the usual mbox setup. Any suggestions would be greatly appreciated! Thanks in advance, Maarten

[Dovecot] deliver looking into root directory for sieve configuration ?
by Guillaume Hilt 03 Jan '09

03 Jan '09

Hi, I'm using dovecot (+sieve), dspam, clamav and postfix with wirtual users and domains. When the server receive an email, I get this error : Jan 2 14:48:52 mail postfix/qmgr[13573]: 89DE1276C42B: from=<postmaster(a)shadowprojects.org>, size=926, nrcpt=1 (queue active) Jan 2 14:48:52 mail deliver(postmaster(a)adomain.fr): chdir(/root) failed: Permission denied Jan 2 14:48:52 mail deliver(postmaster(a)adomain.fr): stat(/root/.dovecot.sieve) failed: Permission denied Jan 2 14:48:52 mail deliver(postmaster(a)adomain.fr): msgid=<495E1B33.5020009(a)shadowprojects.org>: saved mail to INBOX Jan 2 14:48:52 mail postfix/lmtp[13584]: 89DE1276C42B: to=<postmaster(a)adomain.fr>, relay=mail.mydomain.com[/var/run/dspam/dspam.sock], delay=0.07, delays=0.05/0/0/0.01, dsn=2.6.0, status=sent (250 2.6.0 <postmaster@adomain> Message accepted for delivery) Why does it look inside the /root folder for sieve configuration ? All virtual mailboxes are in /home/vmail/DOMAIN/USER/.maildir (owned by postfix:postfix; dspam has been put in the postfix group) I uploaded the following config files in http://hiltg.pastebin.com/ : - main.cf - master.cf - dovecot.conf - dspam.conf (mails are supposed to be delivered to the mailbox by dovecot, which is called by dspam) Any idea please ? Thanks and happy new year to you all, -- Guillaume Hilt
