I have some archived mails in compressed (by bzip2) mboxes and I would like to read them via imap Unfortunately it looks like dovecot crashes when tries to read them :( #v+ kjonca@alfa:~/Mail/Old/Junk%sudo /usr/sbin/dovecot -n [sudo] password for kjonca: # 1.2.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32.7+2 i686 Debian squeeze/sid log_path: /var/log/dovecot log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap listen: alfa.kjonca localhost ssl: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_processes_count: 1 verbose_proctitle: yes mail_privileged_group: mail mail_debug: yes mbox_write_locks: fcntl dotlock mail_plugins: mail_log zlib mail_log_max_lines_per_sec: 0 namespace: type: private separator: / location: maildir:~/Mail/def:LAYOUT=fs:INBOX=~/Mail/def inbox: yes list: yes subscriptions: yes namespace: type: private separator: / prefix: #Old/ location: mbox:~/Mail/Old list: yes subscriptions: yes lda: postmaster_address: root@localhost log_path: ~/log/dovecot.log info_log_path: ~/log/deliver.log mail_plugins: sieve deliver_log_format: msgid=%m : Subject=%s : From=%f :%$ auth default: mechanisms: digest-md5 cram-md5 passdb: driver: pam args: dovecot passdb: driver: passwd-file args: scheme=plain-md5 /etc/security/dovecot.pwd userdb: driver: passwd #v- Then I try to read mailbox: #v+ kjonca@alfa:~/Mail/Old/Junk%mutt -f \=\#Old/Junk/2008.bz2 #v- In logs is: #v+ 2010-03-22 17:03:05 imap-login: Info: Login: user=<kjonca>, method=DIGEST-MD5, rip=127.0.0.1, lip=127.0.0.1, secured 2010-03-22 17:03:05 IMAP(kjonca): Info: Loading modules from directory: /usr/lib/dovecot/modules/imap 2010-03-22 17:03:06 IMAP(kjonca): Info: Module loaded: /usr/lib/dovecot/modules/imap/lib20_mail_log_plugin.so 2010-03-22 17:03:06 IMAP(kjonca): Info: Module loaded: /usr/lib/dovecot/modules/imap/lib20_zlib_plugin.so 2010-03-22 17:03:06 IMAP(kjonca): Info: Effective uid=1000, gid=1000, home=/home/kjonca 2010-03-22 17:03:06 IMAP(kjonca): Info: Namespace: type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes 2010-03-22 17:03:06 IMAP(kjonca): Info: maildir: data=~/Mail/def:LAYOUT=fs:INBOX=~/Mail/def 2010-03-22 17:03:06 IMAP(kjonca): Info: fs: root=/home/kjonca/Mail/def, index=, control=, inbox=/home/kjonca/Mail/def 2010-03-22 17:03:06 IMAP(kjonca): Info: Namespace: type=private, prefix=#Old/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes 2010-03-22 17:03:06 IMAP(kjonca): Info: mbox: data=~/Mail/Old 2010-03-22 17:03:06 IMAP(kjonca): Info: mbox: INBOX defaulted to /home/kjonca/Mail/Old/inbox 2010-03-22 17:03:06 IMAP(kjonca): Info: fs: root=/home/kjonca/Mail/Old, index=, control=, inbox=/home/kjonca/Mail/Old/inbox 2010-03-22 17:03:06 IMAP(kjonca): Info: Namespace #Old/: Using permissions from /home/kjonca/Mail/Old: mode=0700 gid=-1 2010-03-22 17:03:50 dovecot: Error: child 27392 (imap) killed with signal 11 (core dumped) #v- core stack: #v+ kjonca@alfa:~/Mail/Old/Junk%gdb -c ~/core /usr/lib/dovecot/imap [..cut...] Core was generated by `imap [kjonca 127.0.0.1]'.

[Dovecot] dovecot-2.0.beta4 mysql support in Solaris
by Tomi Vainio 22 Mar '10

22 Mar '10

Hi, I've been able to configure --with-mysql in Solaris 10 which has MySQL version 4.0.31 bundled in. Since beta4 build fails due to change in src/lib-sql/driver-mysql.c. I've never used this feature but so I don't need it. This is just a FYI if someone reads mailing list. "driver-mysql.c", line 139: undefined symbol: CLIENT_MULTI_RESULTS "driver-mysql.c", line 448: warning: implicit function declaration: mysql_next_result Tomppa

[Dovecot] Shared mailboxes basics
by Thomas Hummel 22 Mar '10

22 Mar '10

Hello Timo, I'm trying to set up shared mailboxes with dovecot-1.2.11/Maildir. I previsouly used public namespaces with 1.1+ to somehow implement them but I'm looking at the real ones now. I've read the Wiki but I'm still confused or not 100% sure about the following (basic) points : 1. Namespaces prefixes My understanding is that a namespace prefix is just an escape mechanism for the client to access the mailboxes this namespace holds. So the real location is _only_ defined by the "location" directive, independently of what the prefix is. So, for example, If you've got : prefix="foo/bar/" location=maildir:/some/folder/%u mailboxes are physically in /some/folder/%u, not in /foo/bar/some/folder/%u or something am I correct ? 2. Other Users mailboxes RFC234 states that shared mailboxes (which they call "Other Users" mailboxes) are "mailboxes from the Personal Namespaces of other users." Dovecot's Wiki takes as an example : # User's private mail location. mail_location = maildir:~/Maildir # You need to create also a private namespace: namespace private { separator = / prefix = #location defaults to mail_location. inbox = yes } namespace shared { separator = / prefix = shared/%%u/ location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = children } and states : "This creates a shared/ namespace under which each user's mailboxes are." My understanding is that # User's private mail location. mail_location = maildir:~/Maildir and location = maildir:%%h/Maildir implies that mailboxes in both the private and the shared/ namespace are physically in the same location (under the "$HOME/Maildir" directory of the user who shares his mailbox) . Am I correct ? I tried the following set up : namespace private { separator = / location = maildir:/courriel/boites/%u:CONTROL=/courriel/meta/%u:INDEX=/var/dovecot-test/indexes/%1u/%u inbox = yes hidden = no list = yes subscriptions = yes } namespace shared { separator = / prefix = "#shared/%%u/" location = maildir:/courriel/boites/%%u:INDEX=/var/dovecot-test/indexes/%1u/%u/shared/%%u subscriptions = no list = yes # will try children later } the user doveimap has the following mailboxes : # pwd /courriel/boites # ls -l doveimap total 64 drwx------ 5 doveimap Invites 4096 Oct 23 13:38 .Trash drwxr-xr-x 5 doveimap Invites 4096 Oct 27 17:00 .sous drwxr-xr-x 5 doveimap Invites 4096 Oct 27 17:00 .sous.arbo drwxr-xr-x 5 doveimap Invites 4096 Oct 27 17:00 .sous.arbo.rescence drwx------ 5 doveimap Invites 4096 Oct 23 13:43 .testcopy drwx------ 2 doveimap Invites 4096 Mar 15 17:08 cur drwx------ 2 doveimap Invites 4096 Mar 15 17:07 new drwx------ 2 doveimap Invites 4096 Mar 15 17:07 tmp I can perform for instance : * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN] Dovecot test ready. x login doveimap xxxxxxxx x OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS ACL RIGHTS=texk] Logged in 1 setacl INBOX dovepop rl 1 OK Setacl complete. But isn't a client like Thunderbird (3.0.3) supposed to . show me the #shared (even if no one shares mailboxes to me) "folder" (because of list = yes )? . let me share, let's say the .sous.arbo mailbox ? If yes, how ? Or should I first pre-set some acl files ??? For now, it says : "This is a personnal mail folder. It is not shared."

[Dovecot] dovecot-2.0.beta3 tcpwrapper support in Solaris
by Tomi Vainio 22 Mar '10

22 Mar '10

Hi, 2.0 compiles fine in Solaris but and I've found only one glitch so far. Tcpwapper support needs some tweaks. I need to add CPPFLAGS=/usr/sfw/include because tcpd.h is in there. Then also LDFLAGS='-R/usr/sfw/lib -L/usr/sfw/lib' is needed. It would be nice to have --with-tcpwrap-dir or something. After this linking gives an error Undefined first referenced symbol in file deny_severity /usr/sfw/lib//libwrap.so allow_severity /usr/sfw/lib//libwrap.so These are not defined but application itself should define these globally so I've added these to configure and src/util/tcpwrap.c #include <syslog.h> int allow_severity = LOG_INFO; int deny_severity = LOG_WARNING; Tomppa

[Dovecot] Dovecot 1.2.11 renames Maildir filenames on first read of foreign POPstore - how to avoid
by Sam C. Nicholson !! 22 Mar '10

22 Mar '10

Greetings, I'm converting from a custom POPstore ( > 100,000 messages) which is Maildir-like and uses the filename as the UIDL and doesn't store it inside the message. I'm wondering whether there is hope for config-file options to keep devecot from renaming files when it first sees them, or whether I'm going to need to create a new backend for dovecot based on Maildir. The renaming not only blows my current UIDLs, it seems to upset Dovecot's indexing, Cheers! -sam My POPstore looks like this: /zdata/domain/%d/folders/%n/{cur, new, tmp}/ and message filenames like this: msg.yyyy:mm:dd:hh:mm:ss.random I was able to get Dovecot to see the store by the symlink: INBOX -> . Here are the log messages regarding the index warnings: Mar 22 07:45:52 POP3(scion(a)6ix.net): Warning: Fixed a duplicate: /zdata/domain/6ix.net/folders/scion/INBOX/cur/msg.2008:02:20:16:37:56.951.2376 -> 1269258346.M323507P15988.mailbase Mar 22 07:45:52 POP3(scion(a)6ix.net): Warning: Fixed a duplicate: /zdata/domain/6ix.net/folders/scion/INBOX/cur/msg.2008:01:08:00:00:50.25142.18396 -> 1269258346.M323508P15988.mailbase ^ |____Dovecot message name appears to increment here #dovecot -c config -n # 1.2.11: /home/scion/Packages/dovecot-1211/dovecot.conf.short Warning: fd limit 256 is lower than what Dovecot can use under full load (more than 640).

[Dovecot] configure dovecot to read-only ?
by Frank Gadegast 22 Mar '10

22 Mar '10

Hi, I like to configure the use of IMAP to read-only on a special backup system. Users should only be able to read archived email, they should not be able to create folders or delete email. I know how to configure user- or folder-specific acls, but it seems to be a bit complicated to setup a ACL for every user. Any simple global option available ? Kind regards, Frank -- PHADE Software - PowerWeb http://www.powerweb.de Inh. Dipl.-Inform.

[Dovecot] Possible programming error in maildir_mail_get_save_date
by Rainer Weikusat 22 Mar '10

22 Mar '10

The maildir_mail_gate_save_date routine (lib-storage/index/maildir/maildir-mail.c) returns the save date when that was determined by looking at the ctime of the corresponding file. This is different from all other get_save_date routines which either return -1 if the date could not be determined or 0 to signal success. A particular problem caused by this would be that the first_nonexpunged_timestamp routine (plugins/expire/expire-plugin) never finds a not-yet-expired e-mail after the first message in a mailbox has been expunged when using the maildir storage and file ctimes for save dates, causing the expire_mailbox_transaction_commit function (same file) to delete expiry information for the mailbox in question from the expires table despite mails supposed to expire still exist.

[Dovecot] Public Folder for mailinglist with deliver
by Sebastian Heil 21 Mar '10

21 Mar '10

Hello Everybody, I'm looking for a nice way to implement the following: We are running a mail server for system users who are having their own mailbox. Now there's the idea to subscribe for a few mailinglists which are then available for the user per shared/public folder. So they can simply subscribe and unsubscribe with their MUA. For every mailinglist subscription there should exist an own email account with own mail directory. The namespaces are already working (in a test environment). But I haven't found any implementation to realize this nicely with deliver. The possiblities I'm thinking about are: -create a somewhere in userdb a passwd entry for each mailinglist email address with the corresponding directory -create a static userdb entry, but then deliver cannot check if an email address/mailbox exists. I think both ideas aren't a good implementation. So I'm asking you for help. Has someone a similar setup or a little idea how to make this work with deliver. Thanks in advance Sebastian
