[Dovecot] dovecot security with IPv6
by Kārlis Repsons 27 Jun '11

27 Jun '11

Hi Timo, hi all others! In fact, I've only read one person claiming that IPv6 support opens up "too many backdoors" [1], but anyway, as I intend to run just particular services, please give me your opinion if it's insecure to have a dovecot server, which is accessed through a public IPv6 address... (or note just shortly what else could give a firm ground to such claims...) [1] http://forums.gentoo.org/viewtopic-t-882557.html

[Dovecot] Sendmail + dovecot-lda + LDAP
by Василий Яковлев 27 Jun '11

27 Jun '11

Hi, I experince some problems with setting up Sendmail with the LDAP database for virtual mail accounts. Why i'm not writing to the LDAP mailing list? I believe, that the reason of my problem is in configuring dovecot-deliver. What i have: - FreeBSD - sendmail (Version 8.14.4 with LDAP support installed from ports) - Dovecot LDA + dovecot (as pop3/imap) - Cyrus Sasl (authdaemon for authentification) 1. Following http://wiki.dovecot.org/LDA/Sendmail i've set up deliver as LDA. Everything worked fine. 2. Following http://wiki.dovecot.org/HowTo/DovecotOpenLdap i've set up Dovecot to work with tha ldap. Now i can authorize through the client or web interface and get to my maildir. 3. Now, i want my sendmail to accept mail for the account in LDAP database. sendmail.mc: ++++++++++++++++++++++ FEATURE(`local_procmail', `/usr/local/libexec/dovecot/deliver',`/usr/local/libexec/dovecot/deliver -d $u') MODIFY_MAILER_FLAGS(`LOCAL', `-f') ...................................... define(`confLDAP_DEFAULT_SPEC', `-h "localhost" -b "dc=mydomain,dc=ru" -d "cn=dovecot,ou=accounts,dc=mydomain,dc=ru" -MLDAP_AUTH_SIMPLE -P /etc/mail/ldap_pass')dnl LDAPROUTE_DOMAIN(`mydomain.ru')dnl FEATURE(`ldap_routing', `null -T<TMPF>', `ldap -1 -T<TMPF> -v mail -k (&(objectclass=posixaccount)(mail=%0))', `passthru')dnl ...................................... MAILER(procmail) ++++++++++++++++++++++ After re-making the sendmail: ++++++++++++++++++++++ [root@test2 /etc/mail]# sendmail -bv -d60.1 test_user(a)mydomain.ru map_lookup(dequote, test) => NOT FOUND (0) map_lookup(host, mydomain.ru) => mydomain.ru. (0) map_lookup(dequote, test_user) => NOT FOUND (0) map_lookup(ldapmra, test_user(a)mydomain.ru) => test_user(a)mydomain.ru (0) map_lookup(ldapmh, test_user(a)mydomain.ru) => NOT FOUND (68) map_lookup(host, mydomain.ru) => mydomain.ru. (0) map_lookup(dequote, test_user) => NOT FOUND (0) map_lookup(virtuser, test_user(a)mydomain.ru) => NOT FOUND (0) map_lookup(virtuser, @mydomain.ru) => NOT FOUND (0) test_user(a)mydomain.ru... User unknown ++++++++++++++++++++++ It's the problem of the local delivery, i believe. Why? Because after sendmail getting an email it passes it to the LDA, which must check the LDAP (not the passwd!) database for the user, to which this email is send to. Are there some possibilities to solve this problem? I appreciate any help.

[Dovecot] dovecot global sieve script problem
by Dhaval Patel 27 Jun '11

27 Jun '11

I cutover to a new server which uses Postfix & Dovecot to handle emails as opposed to Postfix & Courier in the old server. Below is the contents of my global sieve script and dovecot config info. The dovecot-deliver.log does show that the email is being delivered to INBOX.spam but it ends up in the INBOX instead. If I put the exact same rule in the user script, the emails are delivered into the INBOX.spam folder. Currently as a work around, I created user rules for all users and add this. For most users, it is the only rule. So my question is, why does it not work with the global script? Any help would be appreciated. Thanks, Dhaval ------------ contents of globalsieverc ------------- require ["fileinto"]; # Move spam to spam folder if header :contains "X-Spam-Flag" ["YES"] { fileinto "INBOX.spam"; stop; } ---------------------------------------------------- ------------ dovecot -n output --------------------- # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-686-bigmem i686 Debian 6.0.1 xfs log_timestamp: %Y-%m-%d %H:%M:%S ssl_cert_file: /etc/ssl/certs/secure.consoe.com.pem ssl_key_file: /etc/ssl/certs/secure.consoe.com.key disable_plaintext_auth: no verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mail_location: maildir:/home/vmail/%u mbox_write_locks: fcntl dotlock namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)patel.sh auth_socket_path: /var/run/dovecot/auth-master log_path: /home/vmail/dovecot-deliver.log mail_plugins: sieve global_script_path: /home/vmail/globalsieverc auth default: mechanisms: plain login passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail plugin: sieve: /home/vmail/sieve/%n.sieve sieve_global_path: /home/vmail/globalsieverc --------------------------------------------------------

[Dovecot] Please help with Quota dict mysql configuration
by Denis Iskandarov 24 Jun '11

24 Jun '11

Hello So what i have: centos 5.6 postfix 2.3.3 dovecot 2.0.13 postfixadmin 2.3.3 roundcube 0.5.3 All general things are working right now i can send receive email with ssl connections etc... Now i'm trying to configure additional options like quota and some other plugins like sieve, trash, expire and deleted-to-trash. Configuration of quota is on first place. I have read wiki regarding quota config , dict config but can't make things running. Hope there are normal sample configs you can share with me. I'm total noob in sql, so it's very difficult for me to arrange stuff in a way i need. My configs: dict { quota = mysql:/etc/dovecot/conf.d/sql/dovecot-dict-sql.conf # expire = sqlite:/etc/dovecot/dovecot-dict-sql.conf } dovecot-dict-sql.conf sample i took from postfixadmin docs provided with package, also changed table to quota2 as suggested for dovecot 2: driver = mysql connect = host=localhost dbname=postfix user=postfix password=postfixadmin default_pass_scheme = MD5-CRYPT table = quota2 select_field = current where_field = path username_field = username my sql.conf i took it from tutorial on your wiki : LDA postfix postfixadmin: driver = mysql connect = host=localhost dbname=postfix user=postfix password=postfixadmin user_query = SELECT concat('/home/vmail/', maildir) as home, concat('maildir:/home/vmail/', maildir) as mail, 1001 AS uid, 12 AS gid, concat('maildir:storage=', quota) AS quota FROM mailbox WHERE username = '%u' AND active = '1' #user_query = SELECT maildir, 1001 AS uid, 1001 AS gid, CONCAT('dict:storage=',floor(quota/1000),' proxy::quota') as quota FROM mailbox WHERE username = '%u' AND active='1' password_query = SELECT username as user, password, concat('/home/vmail/', maildir) as userdb_home, concat('maildir:/home/vmail/', maildir) as userdb_mail, 1001 as userdb_uid, 12 as userdb_gid FROM mailbox WHERE username = '%u' AND active = '1' The second user_query string i took from postfixadmin docs. But i dont know how to aply it. If it is better to use with mysql/postfixadmin and after this all i dont how to configure quota.conf (90-quota.conf): plugin { #quota = dirsize:User quota #quota = maildir:User quota #quota = dict:User quota::proxy::quota #quota = fs:User quota } # Multiple quota roots are also possible, for example this gives each user # their own 100MB quota and one shared 1GB quota within the domain: plugin { #quota = dict:user::proxy::quota #quota2 = dict:domain:%d:proxy::quota_domain #quota_rule = *:storage=102400 #quota2_rule = *:storage=1048576 } Please help me with configuration. I really stuck with this thing. And yes i've tried to find solutions on mailing list, but no luck. I want per domain/user quota in mysql. Also space usage to be shown in roundcube. Hope to get proper help ... And sorry... Thanks in advance.
