[Dovecot] forbid some users and machines ?
by Frank Bonnet 07 Dec '09

Hello 1 - Is there a way to forbid log in of some Dovecot's users ? I use NIS as authentication mechanism. 2 - Is it possible to forbid some machines (IP addresses ) to connect to Dovecot server ? Thank you

Hi, I am trying to get dovecot working with postfix, and am coming up against this error message. I have this setting configured in the 'protocol lda' section. I am running v1.1.11 dovecot -n -c /etc/dovecot/dovecot-postfix.conf # 1.1.11: /etc/dovecot/dovecot-postfix.conf # OS: Linux 2.6.31-14-generic x86_64 Ubuntu 9.10 reiserfs log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_greeting_capability: yes first_valid_uid: 6060 mail_privileged_group: mail mail_location: maildir:/var/vmail/%d/%n imap_client_workarounds: outlook-idle delay-newmail auth default: mechanisms: plain login debug_passwords: yes passdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf userdb: driver: sql args: /etc/dovecot/dovecot-mysql.conf socket: type: listen client: path: /var/spool/postfix/private/dovecot-auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail cat /etc/dovecot/dovecot-postfix.conf protocols = imap log_path = log_timestamp = "%Y-%m-%d %H:%M:%S " disable_plaintext_auth = no syslog_facility = mail ssl_disable = yes mail_location = maildir:/var/vmail/%d/%n mail_privileged_group = mail first_valid_uid = 6060 protocol pop3 { pop3_uidl_format = %08Xu%08Xv mail_max_userip_connections = 3 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol imap { mail_max_userip_connections = 10 login_greeting_capability = yes imap_client_workarounds = outlook-idle delay-newmail } protocol managesieve { sieve=~/.dovecot.sieve sieve_storage=~/sieve } protocol lda { postmaster_address=postmaster(a)example.com info_log_path = syslog_facility = mail quota_full_tempfail = yes rejection_reason = Your message to <%t> was automatically rejected:%n%r mail_plugins = cmusieve log_path = auth_socket_path = /var/run/dovecot/auth-master sieve_global_path = /var/sieve/global.sieve } auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ auth_debug_passwords = yes auth default { mechanisms = plain login passdb sql { args = /etc/dovecot/dovecot-mysql.conf } userdb sql { args = /etc/dovecot/dovecot-mysql.conf } user = root socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 user = vmail } client { path = /var/spool/postfix/private/dovecot-auth mode = 0660 user = postfix group = postfix } } } dict { } plugin { } When I run "dovecot -a" I see no mention of the postmaster_address setting.

[Dovecot] virtual domains and SSL certificates
by Dick Middleton 07 Dec '09

07 Dec '09

Hi, This topic has been discussed before e.g: <QUOTE> On 2008-08-07, at 1143, Kacper Wysocki wrote: The problem is that the configuration file specifies only one certificate file for dovecot, which means only one Common Name, which means one cannot provide one server cert that will match mail.foo.com AND mail.bar.com, and either ma...(a)foo.com or bo...(a)bar.com will get a "Security Error: Domain Name Mismatch" in their mail client when connecting through IMAPS. </QUOTE> I bring it up again because I've just been trying the release candidate for Thunderbird 3. This has a config wizard which derives from ones email address the mail server address etc. It doesn't handle SSL virtual mail servers very well because of this problem. I have encountered a web server called Cherokee (http://www.cherokee-project.com) which has virtual server capability that *demands* a different certificate for each virtual server. How can that be I thought? This is what Cherokee documentation says: <QUOTE> SSL Virtual Hosts You might have been told elsewhere that named virtual hosts in SSL cannot be supported without SNI (Server Name Indication) because a web server cannot see the hostname header when the SSL request is being processed. Technically this might have been correct in the past. The first thing that the server has to do is to connect with the other end by using SSL/TLS. The user entered host part of the URI must match the Common Name (CN) provided by the certificate. Since virtual hosts are in use, the CN of the first available certificate may or may not match the one specified in the early stages of TLS negotiation. Cherokee supports the clean and standard method of dealing with this issue called Server Name Indication (SNI) that sends the name of the virtual host during the TLS negotiation. If SNI is supported by your SSL/TLS library, the SSL layer does not need to be restarted. Since the host info can be put in the SSL handshake, things will simply work as long as there is a web browser with SNI support at the other side. Currently every modern web browser supports this, and Cherokee has TLS SNI support for the OpenSSL backends. Note that for SNI to work, client support is required. Web browsers known to support it are Mozilla Firefox 2.0+, Opera 8.0+, Internet Explorer 7 (Vista, not XP) or later and Google Chrome. </QUOTE> If Cherokee can do it why not dovecot? Is this something that is, or could be, being considered? It does assume that TB3 and other mail clients support SNI but whatever, I suspect that once TB3 is released the subject will pop-up more frequently. I'm curious to know the latest thinking. Dick

[Dovecot] Manual files moving and index files
by Kārlis Repsons 04 Dec '09

04 Dec '09

Hello all! My first question about dovecot turns out to be: what if I have something outside of dovecot, which sometimes moves messages out of a mail folder and other times into it? Does that make any problem for dovecot or indexing?

[Dovecot] dovecot-shared Problem
by Darius Bohni 03 Dec '09

03 Dec '09

Hi, first, sorry for my english, i hope u understand me :-/ I try to set up dovecot with imap and maildir. I run into a permission problem. I need to have read and execute rights of all folders and mails for the group (needed by the backup deamon). first I tried with umask, but this only affect folders and no mails. Then I read about dovecot-shared and tried this. Permissions are now ok but and this is a big but., I have troubles with thunderbird. I copied a folder from an pop3 account to the imap account (Inbox->subfolder). Now all mails are unread. OK i mark all as read. Now I move a message to the inbox and back to the subfolder an wonder, the mail is now marked as unreaded again. When i set up the mailboxes without the dovecot-shared file, the behaviour above is gone!! But my permission problem is back :-( Permissions of dovecot-shared is 750 and the mainfolder is 750 with g+s can anybody help me? thank u alot grz. fr3ak4l
