[Dovecot] version 1.2.11 creating symlink loop for config file
by Adrian Pepper 15 Apr '10

15 Apr '10

What is the following at the end of "main_init" in dovecot 1.2.11 (src/master/main.c) intended to accomplish? base_config_path = t_strconcat(settings_root->defaults->base_dir, "/"PACKAGE".conf", NULL); (void)unlink(base_config_path); if (symlink(configfile, base_config_path) < 0) { i_error("symlink(%s, %s) failed: %m", configfile, base_config_path); } } With our compilation parameters and runtime setup it ends up removing the working base_config_path file and making it instead a symlink to itself. (I.e. a non-working loop). Strangely, the one instance of dovecot continues and seems to mostly work. But (for now) I need to put back the proper dovecot.conf before I can restart it. I think that would be the expected result if strcmp(configfile, base_config_path) == 0. Is that in fact not expected to be the case? (See my initial question). I did not expect self-modifying of configuration like this. (See my initial question). Pattern matches (e.g. "config_path") find no apparent mention of this in recent postings.

[Dovecot] imap login fails with "no auth attempts"
by Niels Richter 15 Apr '10

15 Apr '10

Hi, I'm currently facing a strange behaviour of dovecot 1.2.10 (and before): after some days the login into our mail servers stops working for imap-connections. pop3-users can go on with using dovecot. Looking into the logfile I can only find: [...] imap-login: Disconnected (no auth attempts) imap-login: Disconnected: Shutting down (no auth attempts) [...] as a hint what is maybe happening. After restarting the system is working quite well again for some time. There is no extra load and not other special at the server running. The authentication is handled over mysql. This is our dovecot -n output (relevant parts): # 1.2.10: /usr/local/etc/dovecot.conf # OS: FreeBSD 7.2-STABLE i386 ufs protocols: imaps pop3s pop3 imap ssl_ca_file: /usr/local/etc/ssl/... ssl_cert_file: /usr/local/etc/ssl/... ssl_key_file: /usr/local/etc/ssl/... disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login mail_max_userip_connections(default): 20 mail_max_userip_connections(imap): 20 mail_max_userip_connections(pop3): 10 verbose_proctitle: yes first_valid_gid: 0 mail_access_groups: mail mail_privileged_group: mail mail_location: maildir:/usr/... mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_process_size: 512 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): namespace: type: private prefix: INBOX. inbox: yes list: yes subscriptions: yes Do you see anything which is unclear or unnecessary and could lead to a crash of the imap-login process after some time? Thanks for your help! -- Niels.

[Dovecot] Any secret dovecot 2.0 lda configuration documentation anywhere? =)
by Brandon Lamb 15 Apr '10

15 Apr '10

I successfully got imap/pop3 working using 2.0b4, now im trying to also get lda working with exim but im totally confused. I dont know what should run as what user, getting confused on auth sockets, what to call them or set or whatever. My exim runs as user/group mail/mail, dovecot has user dovecot but user mail for mail_user/group settings. At one point running deliver -d user -f user gave me an error userdb lookup not possible with only userdb prefetch.

[Dovecot] pigeonhole: naming and versioning
by Axel Thimm 14 Apr '10

14 Apr '10

Hi Stephan, many thanks for all the work you do on the new sieve parts to dovecot. As a (downstream) packager I have some questions: a) pigeonhole is called a working title - will the final release be called something else like dovecot-sieve again? b) The versioning seems to go from 0.1.15 to 0.1.13. From a packager's POV it would be better to allow a natural version upgrade path. Perhaps the version in hg is just not updated? The reason for these questions/clarifications are that Angel and I are packaging dovecot 2.x betas and matching sieve plugins for allowing more people to a broader testing before the projects go gold. We'd like to have proper naming and versioning in place already for the beta packages. Thanks! -- Axel.Thimm at ATrpms.net

[Dovecot] dovecot-2.0-beta4, lda and sieve: Permission lookup failed from /tmp/Dovecot Delivery
by Felix Leimbach 14 Apr '10

14 Apr '10

Hi all, I'm testing a dovecot-2.0-beta4 and it is great so far, except that I can't get the sieve plugin for the LDA configured. It doesn't find the user's homedir and uses /tmp instead. Thus it never finds any sieve scripts. The log shows that the SQL queries return the correct home path, namely /mnt/data/vmail/example.com/me dovecot: auth: prefetch(me(a)example.com): passdb didn't return userdb entries, trying the next dovecot: auth: sql(me(a)example.com): SELECT CONCAT(homedir, "/", maildir) AS mail, CONCAT(homedir, "/", maildir) AS home, uid, gid FROM postfix_users WHERE email = 'me(a)example.com' dovecot: auth: master out: USER 1 me(a)example.com mail=/mnt/data/vmail/example.com/me/ home=/mnt/data/vmail/example.com/me/ uid=5000 gid=5000 dovecot: lda(me(a)example.com): Effective uid=5000, gid=5000, home=/mnt/data/vmail/example.com/me/ dovecot: lda(me(a)example.com): Namespace: type=private, prefix=, sep=., inbox=yes, hidden=no, list=yes, subscriptions=yes dovecot: lda(me(a)example.com): maildir++: root=/mnt/data/vmail/example.com/me, index=, control=, inbox=/mnt/data/vmail/example.com/me However, the sieve plugin still uses /tmp instead of the home dir and fails: dovecot: lda(me(a)example.com): fs: root=/tmp, index=, control=, inbox= dovecot: lda(me(a)example.com): Namespace : Permission lookup failed from /tmp/Dovecot Delivery Mail dovecot: lda(me(a)example.com): Namespace : Using permissions from /tmp: mode=0777 gid=-1 dovecot: lda(me(a)example.com): Namespace : Permission lookup failed from /tmp/Dovecot Delivery Mail dovecot: lda(me(a)example.com): Namespace : Using permissions from /tmp: mode=0777 gid=-1 dovecot: lda(me(a)example.com): sieve: user has no valid personal script Any idea?

[Dovecot] default domain empty
by Leo Unglaub 14 Apr '10

14 Apr '10

Hi friends, i have a question. I have a running dovecot install on my server and a lot of virtual domains. It works great. The users are logging in with user(a)domain.tld but one old domain must be logged in with only the username only (without @domain.tld). My problem is that in this case the mailbox_localtion don't work. For example: > mail_location = maildir:/var/mail/%d/%n/maildir:INDEX=/var/mail/%d/%n/indizies The variable %d is not replaced with the domain. The dokumentation says: domain part in user@domain, empty if user there's no domain Okay, but is there a way to add a domain to this beause i need the %%d for mailbox sharing. Can i override the domain with a value from the user db or is it possible with a login script or somethink? Thank you a lot Greetings from Austria Leo

hello, to use dovecot 1.2 only for sasl authentication I could set "protocols = none" in dovecont.conf. In Version2 this gave me an error. Instead I had to write "protocols =" into the configfile.

[Dovecot] Dovecot 2.0 - LDA auth-master issues
by Floris Bos 14 Apr '10

14 Apr '10

Hi, I'm running a Postfix+Dovecot+MySQL setup, and am trying to upgrade to Dovecot 2.0 beta 4. The problem I run into is that lda cannot connect to the auth-master socket. == Apr 9 15:29:51 mysql postfix/pipe[3749]: 2AAB04517F: to=<EMAIL-ADDRESS>, relay=dovecot, delay=0.02, delays=0.01/0/0/0.02, dsn=4.3.0, status=deferred (temporary failure. Command output: lda: Error: userdb lookup: connect(/usr/local/var/run/dovecot/auth-master) failed: Permission denied (euid=80(www) egid=1003(dovecot) missing +r perm: /usr/local/var/run/dovecot/auth-master, euid is not dir owner) lda: Fatal: User lookup failed: userdb lookup failed ) == Dovecot seems to set the permission of the auth-master socket to user root, mode 600. In Dovecot 1 there was a "mode" and a "user" option to change this. In Dovecot 2 I can only find an option to change the socket path ("auth_socket_path"), but not it's user or mode. Any idea on how to solve this? Your sincerely, Floris Bos
