[Dovecot] Fatal: Running as root isn't permitted

Hi! It compiles perfect now and works fine without returning the uid in the ldap query. What about the inclusion of the antispam and autocreate plugins in the (source) debian package? Thank you very much. 2008/5/4 Timo Sirainen <tss(a)iki.fi>: > On Sun, 2008-05-04 at 15:19 +0200, Juan Asensio Sánchez wrote: > > mech-gssapi.o: In function `gssapi_krb5_userok': > > /root/tmp/dovecot-1.1.rc4/src/auth/mech-gssapi.c:325: undefined > > reference to `krb5_get_error_message' > > This fixes it: http://hg.dovecot.org/dovecot-1.1/rev/ad0f32abda6d > >

[Dovecot] The CONTROL problem with fs quotas.
by Jorgen Lundman 04 May '08

04 May '08

dovecot-1.0.10 on Solaris 10 x86, with NFS. We currently have the problem that when customers go over their disk quota, the dovecot-uidlist file stops them from logging in. In the interest of solving it, we considered moving the CONTROL file to a different file system. But: 1: Using CONTROL= with "%u" will quite quickly run into the problem that the directory will fill up, and hit the maximum (around 32k) or so. We have 170k users so far, and more are being imported. You could cull some from crontab or similar, but is generally a poor way to solve a problem. 2: We attempted to use CONTROL= with "%h", which would give us full directory hashing, however, we found that when it creates all the directories, it does so as the uid of the first user. So all following users (that hash in at least one part) will fail. Most likely because dovecot has already setuid()ed. Pre-creating the hashes is not feasible. 3: Using 2, we could change umask to "0000" and hence it does not matter than all directory hash node are owned by a user's id, but this unfortunately includes all other directories, and having all directories at 777 is not an option. Now, naturally, I can easily patch dovecot to call mkdir_parents with 0777 only for CONTROL. But I would rather not have local patches, meaning upgrades will be difficult. It would be preferable if: => Dovecot would call "mkdir_parents" on "%h" _before_ setuid, but create the final directory after. OR, Dovecot support (at least 2 level) directory hashing when specifying CONTROL=%1/%2/%u OR, The ability to disable dovecot-uidlist (in memory is fine). (Setting INDEX=memory does not work for CONTROL=). Are there other solutions out there? -- Jorgen Lundman | <lundman(a)lundman.net> Unix Administrator | +81 (0)3 -5456-2687 ext 1017 (work) Shibuya-ku, Tokyo | +81 (0)90-5578-8500 (cell) Japan | +81 (0)3 -3375-1767 (home)

[Dovecot] used_file_size too large
by Anders 04 May '08

04 May '08

Hi. Just got this error (1.1.rc4), is it something to worry about? Corrupted index cache file /.../Maildir/.Sent/dovecot.index.cache: used_file_size too large This is a shared mailbox with concurrent access. In general, can that usage pattern mess up the index? I am guessing "no", which is why I worry slightly about the warning. Cheers, Anders.

[Dovecot] Can't receive mail for virtual user
by Jeremy Gillick 04 May '08

04 May '08

I followed the dovecot instructions ( http://wiki.dovecot.org/HowTo/SimpleVirtualInstall) to create a simple virtual user installation with the /etc/dovecot/passwd file. However, whenever I try to send a message to the virtual user, Postfix has a problem delivering it. Postfix is delivering messages to ~/Maildir, but Dovecot is trying to use /home/vmail/. How can I get the 2 apps to work together? I've set up SASL, SSL and Dovecot LDA.

[Dovecot] Client can't connect to SMTP

I've just installed Dovecot and Postfix and my email client (Mac Mail) cannot authenticate with the SMTP server.

[Dovecot] Dovecot 1.1: Ignoring Trash/Junk for maildirsize?
by richs＠whidbey.net 04 May '08

04 May '08

Hi all, We're testing Dovecot 1.1rc3, but have run into a snag with IMAP Quota's and the way Trash and Junk folders can be handled. Our MTA (Exim) quota configuration uses this option: maildir_quota_directory_regex = ^(?:cur|new|\.(?!Junk$)(?!Trash$).*)$ This completely excludes "Junk" and "Trash" from the "maildirsize" file and quota calculations. Dovecot 1.0 could do this using "ignore=Trash" (although only on one folder). Is there any way to duplicate this behavior in Dovecot 1.1? We see that "quota_rule" can be used to set an unlimited quota (storage=0), but for some reason Dovecot still records their tallies in "maildirsize", which breaks the MTA. Thanks! -Rich

[Dovecot] Cross-Realm Krb5 Patch
by Zachary Kotlarek 04 May '08

04 May '08

I've updated my krb5 cross-realm auth patch for dovecot 1.1-rc4; there are not any (intentional) changes in functionality from the last patch, the diff just didn't apply cleanly anymore. As before the most recent version of the patch is available at: http://zinux.cynicbytrade.com/svn/servers/dovecot/cross-realm.diff.bz2 I see the cross-realm patch for Solaris made it into the mainline. What if anything can I do to encourage the mainline adoption of my non- Solaris patch? Zach

[Dovecot] Patch for zlib and maildir for 1.0.13
by Richard Platel 04 May '08

04 May '08

When using the zlib plugin with maildir and copying with hardlinks, if a compressed message is copied, the 'Z' suffix on the file isn't copied, so the new message isn't uncompressed when it's fetched. I wasn't smart enough to figure out a clean way to carry a file suffix through a copy, so I changed how the zlib-plugin detects if a message is compressed. This patch peeks at the first two bytes of the message looking for the zlib header. -- Richard Platel Tucows

[Dovecot] 1.1rc4 problem with maildir++ quota and POP3
by Laurent Papier 04 May '08

04 May '08

Hi, it looks like there is a bug (in dovecot or in my config) with quota on maildir mailboxes when accessed via POP3. The maildirsize is not created when not already present (even after a DELE + QUIT command). The quota limit (the first line of maildirsize) is not updated if values are not in sync with those in the database. If maildirsize is present, DELE commands are correctly reported in maildirsize. maildirsize is correctly updated when the same mailbox is accessed in IMAP or mail is delivered with dovecot LDA. Here is my config. Timo 'dovecot -n' does not show the lda config part... # 1.1.rc4: /etc/dovecot.conf protocols: imap pop3 ssl_disable: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_greeting: please to meet you login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no login_processes_count: 100 login_max_processes_count: 512 max_mail_processes: 3072 mail_uid: 1000 mail_gid: 1000 mail_location: maildir:~/ mmap_disable: yes maildir_stat_dirs: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugins(default): imap_quota quota mail_plugins(imap): imap_quota quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 imap_client_workarounds(default): outlook-idle imap_client_workarounds(imap): outlook-idle imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls auth default: user: nobody passdb: driver: sql args: /etc/dovecot-mysql.conf userdb: driver: sql args: /etc/dovecot-mysql.conf userdb: driver: prefetch socket: type: listen master: path: /var/run/dovecot/auth-master mode: 432 user: mailonly group: mailonly plugin: quota: maildir quota_rule2: Trash:storage=12288:messages=100 --- SQL queries ---- # prefetch auth password_query = SELECT cpasswd as password, home as userdb_home, concat('*:bytes=',quotas,':messages=',quotai) AS userdb_quota_rule FROM `mail` WHERE email='%u' # for delivery user_query = SELECT home, concat('*:bytes=',quotas,':messages=',quotai) AS quota_rule FROM `mail` WHERE email='%u' -- Laurent Papier - 03 88 75 80 50 Admin. système - SdV Plurimedia - <http://www.sdv.fr/>
