[Dovecot] Test Environment Question
by Stewart Dean 10 Jan '08

10 Jan '08

I have my master IMAP server running DC V1.0.10. The homedir and INBOXdir are physically resident there and NFS exported (no caching) to 3 other machines. I have installed V1.1beta13 on one of them (which thus accesses the homedir/INBOXdir remotely) and plan to have a limited community test-drive it there. Are there any hazards or drawbacks in doing this? While the homedirs and INBOXdirs are thus shared, I have it so that each machine has its own local index directory and /var/run dir. Comments or dire warnings?

Ok, did that. And looking at all the alerts it appears to be any file that deliver is trying to write under /home/vmail. My users are all virtual and they all exist like: /home/vmail/example.com/john typical permissions: -rw------- 1 vmail vmail 464 2008-01-01 20:06 dovecot.index.log but for some reason even though deliver is setup to run as vmail:vmail it is still having permission problems. dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/deliver -d ${recipient} ????

[Dovecot] [dovecot][configure] docdir option lost
by Guth 10 Jan '08

10 Jan '08

Hi, While building dovecot-1.0.10 i've a trouble with --docdir configure option. It seems this option overload is "lost" during makefiles recurse generation (i didn't check others overload). Following are config.log and Makefiles cuts : ------------------- $ grep docdir dovecot-1.0.10/config.log dovecot-1.0.10/Makefile dovecot-1.0.10/doc/Makefile dovecot-1.0.10/doc/wiki/Makefile dovecot-1.0.10/config.log: $ ./configure --prefix=/usr --with-gssapi --with-ldap --with-sql --with-mysql --sysconfdir=/etc --localstatedir=/var --mandir=/usr/man --with-docs --docdir=/usr/doc/dovecot-1.0.10 dovecot-1.0.10/config.log:docdir='/usr/doc/dovecot-1.0.10' dovecot-1.0.10/Makefile:docdir = /usr/doc/dovecot-1.0.10 dovecot-1.0.10/doc/Makefile:docdir = $(datadir)/doc/dovecot dovecot-1.0.10/doc/wiki/Makefile:docdir = $(datadir)/doc/dovecot ------------------- I'll correct it in a dirty way (sed is my friend after Makefiles creation) because i want it built quickly, but i guess it shouldn't be hard to avoid this problem in futures releases. -- Guth

[Dovecot] virtual domains/users and LDAP
by Anil 10 Jan '08

10 Jan '08

I have two suffixes in LDAP with users, e.g. ou=People, o=example.com ou=People, o=somethingelse.com I have the following two users: dn: uid=test1, ou=People, o=example.com uid: test1 mail: test(a)gmail.com dn: uid=test2, ou=People, o=somethingelse.com mail: test(a)yahoo.com uid: test2 The users login to IMAP as: test1(a)examle.com and test2(a)somethingelse.com. Here's an (excerpt) of the dovecot.conf file I am using: auth_bind = yes base = ou=People,o=%d scope = onelevel pass_attrs = mail=user pass_filter = (uid=%n) userdb static { args = uid=vmail gid=vmail home=/var/mail/apps/%d/%n } The problem I am seeing when the user logs in, the home dir is getting created incorrectly: Jan 3 14:08:12 vds5 dovecot: [ID 107833 mail.info] imap-login: Login: user=<test(a)gmail.com>, method=PLAIN, rip=, lip= Jan 3 14:08:12 vds5 dovecot: [ID 107833 mail.info] IMAP(test(a)gmail.com): Effective uid=500, gid=500, home=/var/mail/apps/gmail.com/test Jan 3 14:08:12 vds5 dovecot: [ID 107833 mail.info] IMAP(test(a)gmail.com): maildir: data=/var/mail/apps/gmail.com/test/Maildir ... I was expecting it to create the home dir under: /var/mail/apps/example.com/test1, since that is what they are logging in with. Any ideas? I am actually surprised that it even let me login with this configuration, something looks odd in this setup. :) Thanks, Anil

[Dovecot] %d not recognized with LDAP

I saw the recent threads but didn't help for me. Here's my configuration: The domain isn't getting expanded as per logs: Jan 4 08:06:40 vds5 dovecot: [ID 107833 mail.info] IMAP(admin): maildir: data=/var/mail/apps//admin/Maildir # 20080102: /usr/local/dovecot/etc/dovecot.conf listen: *:143 ssl_disable: yes disable_plaintext_auth: no login_dir: /usr/local/dovecot/var/run/dovecot/login login_executable: /usr/local/dovecot/libexec/dovecot/imap-login login_log_format_elements: user=<%n@%d> method=%m rip=%r lip=%l %c login_max_connections: 64 max_mail_processes: 128 mail_location: maildir:/var/mail/apps/%d/%n/Maildir mail_debug: yes auth default: passdb: driver: ldap args: /usr/local/dovecot/etc/dovecot-ldap.conf userdb: driver: static args: uid=vmail gid=vmail home=/var/mail/apps/%d/%n Here's the relevant LDAP configuration: auth_bind = yes pass_attrs = uid=user pass_filter = uid=%n I tried setting the mail_location to: maildir:~/Maildir and explicitly specifying the full path, but still the Maildir is getting created with out the %d. Of course, the user is logging in with "admin(a)domain.com". Any ideas?

[Dovecot] Problems with AUTH=PLAIN in pop3
by Maykel Moya 10 Jan '08

10 Jan '08

I'm using Dovecot (1.0.10) locally to test SugarCRM. When I tried to set up a mail account in Sugar, it complains with -- SECURITY PROBLEM: insecure server advertised AUTH=PLAIN Please check your settings and try again. -- don't know if that behaviour is a bug or a feature of php-imap. The case is that I'm unable to set up the mail account in Sugar. Timo answered to me on IRC about Dovecot assuming that a connection from the same ip is considered secured. I'd rebuild Dovecot with the following patch: --- dovecot-1.0.10/src/pop3-login/client.c.orig 2008-01-05 00:44:14.000000000 -0500 +++ dovecot-1.0.10/src/pop3-login/client.c 2008-01-05 00:44:30.000000000 -0500 @@ -331,7 +331,7 @@ client->created = ioloop_time; client->refcount = 1; client->common.tls = ssl; - client->common.secured = ssl || net_ip_compare(ip, local_ip); + client->common.secured = ssl; client->common.local_ip = *local_ip; client->common.ip = *ip; --- but still not able to make it not accept AUTH PLAIN authentication from the same ip. I'm missing something? On the other hand, if I set disable_plaintext_auth to yes I cannot use the classic USER/PASS pop3 verbs. I'm not sure what the POP3 related RFCs mandates with respect to this.

[Dovecot] Imap assertion (dovecot-1.1.beta13)
by Nuno Lopes 10 Jan '08

10 Jan '08

Hi, I continue testing the beta versions and have seen a great improvement over the last few ones. On beta13 I'm seeing the following assert on some client folders: file index-mail.c: line 759 (index_mail_stream_destroy_callback): assertion failed: (mail->data.destroying_stream) If you need I can try and reproduce this in a more controled environment to pinpoint the problem. Thanks, -- Nuno Lopes
