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.

[Dovecot] Problems with AUTH=PLAIN in pop3
by Maykel Moya 11 Jan '08

11 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 … [View More]

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.

[Dovecot] Switch from courier to dovecot
by Richard G Riley 10 Jan '08

10 Jan '08

I have an courier IMAP server running. To get sib dirs working I had to rename them all to begin with a period ".". e.g Maildir Maildir/{cur,new,tmp} Maildir/.account1/{cur,new,tmp} Maildir/.account2/{cur,new,tmp} Maildir/.account3/{cur,new,tmp} etc If I uninstall Courier and install dovecot, will these "period" dirs be seen by default? I am fairly new to this and sometimes it seems that Maildir format requirements vary a lot depending on client or server. Thank you for your help.

[Dovecot] OT: ctimes

10 Jan '08

I am going to convert my 32-bit Debian system to a 64-bit Debian system today. But, after I move my maildir files over to the new hard drive the ctimes are going to get modified to current time and mess up my automatic purge scripts for the Deleted Items folders. Is it possible for me to either keep the existing ctimes or is it possible for me to modify the ctimes to the date headers of the emails after I move the files? Thanks, Jeff

[Dovecot] Dovecot indexing questions
by Asheesh Laroia 10 Jan '08

10 Jan '08

I was playing with Dovecot 1.1 full text indexing through Squat in late October, which was working pretty well. I wanted to ask about this behavior I had: When an email arrives in INBOX using procmail (which delivers to my Maildirs), and I see it in Dovecot, when I next do a search (IMAP SEARCH TEXT) of that folder, the search takes a long time. Successive searches are lickety-split. My question is: Can there be an option to "index greedily"? As soon as Dovecot sees the message, I'd … [View More]

[Dovecot] Logging to stderr

[Dovecot] Sendmail, procmail, dovecot and quota

I have Fedora 7 from a standard installation running sendmail, procmail and dovecot 1.0 installed on a single partition. I now need to set up mail quotas for most of the users but not all. Just protecting /var/spool/mail/$LOGNAME is probably good enough for me. Since I just want mail quotas and the installation is on just 1 partition I don't have an easy way to use file system quotas. By reading through the dovecot documentation and list archives I have the feeling that this is possible with … [View More]

[Dovecot] Upgrading a live running dovecot - how?

06 Jan '08

Hi Guys, This has bitten us twice now. We're running Gentoo and emerge (ie compile) a new version of Dovecot thinking we can finish that then restart Dovecot in our own time. It seems that Dovecot immediately starts to use the newly compiled Dovecot binary and we get version mismatch errors preventing access. Would be good if Dovecot behaved in such a way that it kept on using the old version (held in memory) until it was restarted where it then loaded the new version. Dan

Hi, Ok, here's my setup, each virtual user has a home directory as follows: /virtusers/<v_userid> and per the INBOX directive in the dovecot.conf file I also have a file as follows: /var/mail/<v_userid> Now, I've followed the directions as outlined here: http://wiki.dovecot.org/LDA/Sendmail But every time I send mail to one of my virtual users, I get this message The original message was received at Sat, 5 Jan 2008 14:22:51 -0700 (MST) from wa-out-1112.google.com [209.85.… [View More]

[Dovecot] help using sendmail LDA
by Anil 05 Jan '08

05 Jan '08

I am stuck. I get nothing in the logs (about deliver). Sendmail complains about "User unknown". I am not sure I have my sendmail.mc configured right, can someone confirm or give me some sample config files that make use of Dovecot+LDAP and sendmail LDA? Dovecot is running as root. I am a little confused, so the auth-master is not even needed? (the whole socket listen {}, since I am using static userdb and the user information was already found at authentication/login) Thank You! # 20080102: … [View More]

[Dovecot] Optimizing POP3 performance?
by Sebastian Färber 04 Jan '08

04 Jan '08

Hello, I recently migrated to Dovecot from Courier-IMAP and i'm very happy with the IMAP Performance and Dovecot in general. The server is running qmail-ldap and i'm still using the qmail pop3 daemon for the POP3 users. Because i want to get rid of qmail completely (switching to exim) i just tried to replace the qmail pop3 daemon with dovecot too. Immediately after the migration the server became basically unusable because of the high I/O Load caused by the dovecot pop3 daemon. I did some … [View More]

[Dovecot] Compile error introduced in b13 (Solaris 10)
by mikkel＠euro123.dk 04 Jan '08

04 Jan '08

Any news on the b13 compile issue on Solaris 10 (both Sparc and X86)? Would be nice to know whether it's our own headache or something thats not supposed to be and thus expected to be fixed in the next release. Just to be clear this didn't occur in any other release (I've compiled all previous v1.1 betas on the same setup including b12).

[Dovecot] Building path to maildir
by Michel Bulgado 03 Jan '08

03 Jan '08

I have the following situation and I need help from all you people I have dovecot 0.99.11 and i want to migrate to a superior version like dovecot 1.0 looking forward to implement quotas in my system , and use the function deliver with postfix. My Scenario is as follow Dovecot + LDAP (ADS) + postfix My actual version is : 0.99.11 This is my actual configuration: Protocols = imap pop3 imap_listen = * pop3_listen = * login_dir = /var/run/dovecot-login login = imap login = pop3 … [View More]default_mail_env = maildir:/var/spool/virtualmail/%d/%n mbox_locks = fcntl auth = dovecot-auth auth_mechanisms = plain auth_default_realm = CASA.CULT.CU auth_userdb = ldap /etc/dovecot-ldap.conf auth_passdb = pam dovecot auth_user = root auth_verbose = yes auth_debug = yes dovecot-ldap.conf hosts = ldap.casa.cult.cu base = ou=CASA,dc=casa,dc=cult,dc=cu dn = cn=unix-conector,cn=Users,dc=casa,dc=cult,dc=cu dnpass = ***** ldap_version = 3 deref = never scope = subtree user_global_uid = 500 user_global_gid = 500 user_attrs = mail,/var/spool/virtualmail/%d/%n,,,, user_filter = (&(objectClass=user)(!(objectClass=computer))(sAMAccountName=%n)) I see many changes in this new version. One of them is : -Renamed default_mail_env to mail_location - many changes in ldap queries With the new version my problem is when to dovecot tries to detect or builds the way where it´s stored the mailbox of my users. In /var/spool/virtualmail/%d/%u , it does not detect the domain when asking to my active directory (w2k) and consequently takes a value of my default realm = casa.cult.cu in this case the default domain where authenticate my users. My configuration in the new version of dovecot: protocols = imap pop3 protocol imap { listen = * } protocol pop3 { listen = * } login_dir = /var/run/dovecot/login login_chroot = yes login_greeting = Dovecot ready. mail_location = maildir:/var/spool/virtualmail/%d/%u mail_debug = yes mbox_read_locks = fcntl mbox_write_locks = fcntl protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota } protocol lda { postmaster_address = postmaster(a)example.com mail_plugins = quota auth_socket_path = /var/run/dovecot/auth-master } auth_executable = /usr/libexec/dovecot/dovecot-auth auth_verbose = yes auth_debug = yes auth default { mechanisms = plain passdb pam { args = dovecot } userdb ldap { args = /etc/dovecot-ldap.conf } userdb prefetch { } user = root socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = virtualmail group = virtualmail } } } dict { } plugin { quota = maildir:storage=10240 } user_attrs = mail,/var/spool/virtualmail/%d/%n,,,, The attribute mail in the old version returns to me user(a)casa.com or user(a)casa.cult.cu this way dovecot can build the way with no problems at all. But in this late version something is happening, it only takes the value %n= user , but not %d = domain . It´s not working. do you have any idea how I can solve this I beg your pardon for my poor English. ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

[Dovecot] Delay on failed pw attempts
by Dean Brooks 02 Jan '08

02 Jan '08

Hi, Is there a way, or can a way be added, to add an "auth_failed_delay=10s" style option that would put in an artificial delay after a failed password attempt? As it stands now, Dovecot seems highly vulnerable to widescale brute-force password dictionary scans. Even if it's not configurable, can a delay be hardcoded to something like, say, 10 or 15 seconds? -- Dean Brooks dean(a)iglou.com

[Dovecot] deliver triggering SELinux AVC denials
by Gerry Reno 02 Jan '08

02 Jan '08

I setup postfix/dovecot on a new machine and now all works well with the small exception of dovecot triggering selinux avc denials on some temp... files here is a sample alert: Summary SELinux is preventing /usr/libexec/dovecot/deliver (dovecot_deliver_t) "link" to temp.localhost.678.40caaf5592891c46 (user_home_dir_t). Detailed Description SELinux denied access requested by /usr/libexec/dovecot/deliver. It is not expected that this access is required by /usr/libexec/… [View More]dovecot/deliver and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access. Allowing Access Sometimes labeling problems can cause SELinux denials. You could try to restore the default system file context for temp.localhost.678.40caaf5592891c46, restorecon -v temp.localhost.678.40caaf5592891c46 If this does not work, there is currently no automatic way to allow this access. Instead, you can generate a local policy module to allow this access - see http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385 Or you can disable SELinux protection altogether. Disabling SELinux protection is not recommended. Please file a http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against this package.

[Dovecot] my.cnf reading support in MySQL backend

I hope this ml is the right place to send this... Anyway, I'd very much like for the MySQL backend to call mysql_options, so that it'll read the settings defined in MySQL's my.cnf under the [client] section. This allows to set a whole slew of MySQL specific settings for the MySQL connection, for example to enable the compressed protocol, set charsets, enable SSL client verification, and much more. A patch is attached that implements this. See http://dev.mysql.com/doc/refman/5.0/en/mysql-options.… [View More]
