Hi all, This is the first time I used Dovecot and it's perfectly run : dev# ps ax | grep dove 77332 ?? Ss 0:00.30 /usr/local/sbin/dovecot -c /usr/local/etc/dovecot.con 77333 ?? S 0:00.10 dovecot-auth 77334 ?? I 0:00.02 dovecot-auth -w 81495 0 S+ 0:00.00 grep dove But when I try to connect to Dovecot's POP3 Server : dev# telnet 127.0.0.1 110 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. +OK Dovecot ready. user bogi +OK pass bogi Connection closed by foreign host. Is there something I missed in Dovecot's configuration? This is my configuration : dev# dovecot --version 1.2.16 dev# dovecot -n # 1.2.16: /usr/local/etc/dovecot.conf # OS: FreeBSD 8.2-RELEASE i386 protocols: pop3 listen: 127.0.0.1:110 ssl: no disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/pop3-login verbose_proctitle: yes first_valid_uid: 1000 first_valid_gid: 1000 mail_privileged_group: mail mail_location: mbox:~/mail/:INBOX=/var/mail/%u mail_executable: /usr/local/libexec/dovecot/pop3 mail_plugin_dir: /usr/local/lib/dovecot/pop3 pop3_client_workarounds: outlook-no-nuls oe-ns-eoh lda: sendmail_path: /usr/sbin/sendmail auth default: mechanisms: plain login username_format: %Lu passdb: driver: pam args: session=yes dovecot userdb: driver: passwd args: blocking=yes socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 master: path: /var/run/dovecot/auth-master mode: 384

[Dovecot] vacation problem with sieve and sogo
by Pablo Luchetti 18 May '11

18 May '11

Hi, I have a problem with dovecot's sieve and SOGo ( http://www.sogo.nu/ ) I have installed last version of sogo ( 1.3.6) in one virtual machine with ubuntu, lucid. In another virtualmachine with ubuntu jaunty is running dovecot ( 1:1.1.11-0ubuntu4.1 ) When try to activate vacation function, after the "PUTSCRIPT "sogo" command, the manage-sieve answer: NO "Script name 'sogo' is reserved for internal use." And fails. But I found, telneting the mail server on port 2000 that if I change script name, all works fine: SETACTIVE "" OK "No scripts currently active." PUTSCRIPT "prueba" {536+} require ["vacation"]; if allof ( not exists ["list-help", "list-unsubscribe", "list-subscribe", "list-owner", "list-post", "list-archive", "list-id", "Mailing-List"], not header :comparator "i;ascii-casemap" :is "Precedence" ["list", "bulk", "junk"], not header :comparator "i;ascii-casemap" :matches "To" "Multiple recipients of*" ) {vacation :days 1 :addresses ["pluchetti(a)example.org", "pablo.luchetti(a)example.org"] text: hoy es 27 de abril de 2011, y estoy probando el nuevo sogo. 10:40 . ; } redirect "pllis(a)educ.ar"; keep; OK "Putscript completed." SETACTIVE "prueba" OK "Setactive completed." logout OK "Logout completed." Connection closed by foreign host. So, the question is: Why does this happen? How can I fix it ? Any ideas? Here are dovecot's version and config: # dovecot --version 1.1.11 # dovecot -n # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.28-18-server i686 Ubuntu 9.04 log_path: /var/log/mail/dovecot-msa.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s ssl_cert_file: /etc/ssl/local/WILD.jil_01+CHAIN.crt ssl_key_file: /etc/ssl/private/WILD.jil_01.key login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_greeting: JIL mail server ready. first_valid_uid: 106 last_valid_uid: 106 first_valid_gid: 112 last_valid_gid: 112 mail_privileged_group: mail mail_uid: vmail mail_gid: vmail mail_location: maildir:~ mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 auth default: mechanisms: plain login user: vmailauth passdb: driver: ldap args: /etc/dovecot/ldap-auth-userdb.conf userdb: driver: ldap args: /etc/dovecot/ldap-auth-userdb.conf socket: type: listen client: path: /var/spool/postfix/private/auth-client mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail plugin: sieve: ~/sieve/s0g0.sieve Thanks!!

[Dovecot] IMAP message ID bad for very old message
by a.smith＠ukgrid.net 17 May '11

17 May '11

Hi, I just noticed that the ordering by message ID when accessing my email via IMAP is messed up. I'm looking in the INBOX that contains 11757 emails. For some reason a load of emails from 2009 and 2010 are being listed near the top, for example I have a message with ID 11441 from 2009 where it definitely shouldn't be, its all mixed in with emails from 2011 there. Info from LDAP is: * 11441 FETCH (FLAGS (\Answered \Seen) INTERNALDATE "27-Mar-2009 09:14:10 +0000" RFC822.SIZE 5772 ENVELOPE ("Fri, 27 Mar 2009 09:15:09 -0000" "MyC IP on CBL" (("Patrick XXXXXXXX- XXXXXXXX" NIL "patrick" "XXXXXXXX.co.uk")) (("Patrick XXXXXX- XXXXXXXX" NIL "patrick" "XXXXXXX.co.uk")) (("Patrick xxxxxx - xxxxxxx" NIL "patrick" "XXXXXXXX.co.uk")) (("Andy Smith" NIL "a.smith" "ukgrid.net")) (("Frank XXXXXXX" NIL "frank" "XXXXXXXXXXX.co.uk")(NIL NIL "Tim.XXXXXXXX" "XXXXXX.org")) NIL NIL "<6937D025FA924E73B8C839858C27AEBF@PatrickDesktop>")) I'm using maildir format, and the actual file date looks fine too: -rw-rw---- 1 vmail vmail 5627 Mar 27 2009 1238145250.H86871P67126.mx1.ukgrid.net:2,RS I am testing IMAP via telnet (originally noticed the problem viewing mail via HORDE/IMP). My system is FreeBSD 8.2, Dovecot 2.0.11. What might cause this behaviour? thanks Andy.

[Dovecot] Permission lookup failed with imap
by Alex 17 May '11

17 May '11

Hi all, I'm still trying to troubleshoot my problem with dovecot-2.0.11 and creating "mail/mail" directories for a reason unknown to me, so I enabled mail_debug. It's now printing this: May 15 21:39:33 mail dovecot: imap(gdadmin): Debug: Namespace : Using permissions from /home/gdadmin/mail: mode=0755 gid=-1 May 15 21:39:33 mail dovecot: imap(gdadmin): Debug: Namespace : Permission lookup failed from /home/gdadmin/mail/mail/INBOX. Trash That file (INBOX.Trash) does exist at that location and is readable. It prints that line three times for each of INBOX.Sent, INBOX.Trash, and INBOX.Drafts. Also notice that it is creating /home/user/mail/mail. My mail_location is set to "mbox:~/mail:INBOX=/var/spool/mail/%u", so I'm really confused. I really hope someone has some ideas! Thanks so much, Best, Alex

It seems that the error is only occur with postfix pipe command. Any hints?

[Dovecot] when the user has no home directory
by Dave Yost 16 May '11

16 May '11

A user on our server for some reason didn't have a home directory. As a result, the pop3 server was complaining. Apple's Mail app reported that the server said: The attempt to send data to the server "(null)" failed. It would be nice if the server would say something to the effect that the connection failed because the user account has no home directory. Thanks

[Dovecot] user_query and mail_plugins in database
by Ralf Zimmermann 16 May '11

16 May '11

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I have a problem with mail_plugins in dovecot-2.0.x. I will use mail_plugins within a database, so that I can define plugins for users in the database. But I get errors like this. - -----------------------------%<------------------------------------ lmtp(3933): Error: Can't load plugin imap_quota_plugin: Plugin is intended to be used only by imap binary (we're lmtp) - -----------------------------%<------------------------------------- Here my options from the configuration: - -----------------------------%<------------------------------------- mail_plugins = " acl quota" protocol lmtp { mail_plugins = " acl quota sieve" } protocol lda { mail_plugins = " acl quota sieve" } protocol imap { mail_plugins = " acl quota imap_quota imap_acl autocreate" } - -----------------------------%<-------------------------------------- Every protocol uses own mail_plugin definitions. So I create the following user_query: user_query = SELECT LOWER(login) AS user,home,mail,5000 AS uid,5000 AS gid,CONCAT('*:storage=',quota_mb,'MB') AS quota_rule,acl_groups,case when '%s'='lda' then 'acl quota sieve' when '%s'='lmtp' then 'acl quota sieve' when '%s'='doveadm' then 'acl quota' when '%s'='sieve' then 'acl quota' else mail_plugins end as mail_plugins FROM virtual_users WHERE ( login='%u' OR email='%u' ) AND enabled IS true; Now the configuration works. Can I use a simpler solution to configure this functionality?

[Dovecot] dovecot authentication failing
by David Mehler 16 May '11

16 May '11

Hello, I'm running dovecot 2.0.x on a centos 5.6 machine. This is a new installation, I haven't even opened the firewall to it yet. I was trying to telnet localhost 143 and 110 trying to authenticate a user. I'm getting authentication failure in my maillog but no details. Here's the one line I get in my maillog: May 14 15:33:42 ohio dovecot: pop3-login: Aborted login (auth failed, 1 attempts): user=<user(a)example.com>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Here's a doveconf -n: # 2.0.12: /etc/dovecot/dovecot.conf # OS: Linux 2.6.38.3-linode32 i686 CentOS release 5.6 (Final) ext3 auth_default_realm = domain.com auth_mechanisms = plain login base_dir = /var/run/dovecot/ disable_plaintext_auth = no listen = * mail_location = maildir:/var/spool/mail/vhosts/%d/%u maildir_very_dirty_syncs = yes mbox_write_locks = fcntl passdb { args = scheme=CRYPT username_format=%u /etc/dovecot/users driver = passwd-file } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix user = postfix } } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem Here's how I constructed my users file: # # Passwd-file for use with dovecot authentication # Used in a virtual setup # Username:{scheme}HashedPassword:UID:GID:: user:{SSHA512}hbLu+pCmhmtyKEwyAs3wv3kvHD/ryr0MoXOAq3VdB7X/g8qIE/xE9BG+eI4jhFk9pTyiCltPCjZxv5/+yK1wll2LNcw= :5000:5000:: My goal is to use this with a postfix virtual mailbox setup, the postfix part is already in place. The mailbox base is /var/spool/mail/vhosts and under that there's example.com which is the domain and under that the various users one just called user for this example. The Uid and Gid 5000 is the same one the postfix vmail user is running as that's the user who handles the virtual mailbox domains. I'm suspecting my issue is in my users file or the definition of it in passwd-file{ i've been over the wiki for 2.0.x dovecot, this was definitely worth the upgrade by the way, and thus far have not found an answer. I'd appreciate any help. Thanks. Dave.
