Hi, I upgraded (in place upgrade, preserving my dovecot configs) to a newer release of ubuntu in order to gain access to slightly newer Dovecot release and be able to use Dsync for migration from Cyrus, here is my doveconf -n output: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.5.0-44-generic x86_64 Ubuntu 12.10 auth_debug = yes auth_default_realm = whatever.com auth_master_user_separator = * auth_socket_path = /var/run/dovecot/auth-master imapc_features = rfc822.size imapc_host = oldmail.whatever.com imapc_master_user = cyradmin imapc_password = <password hidden> mail_chroot = /var/vmail mail_debug = yes mail_gid = 5000 mail_location = maildir:~/Maildir mail_prefetch_count = 20 mail_privileged_group = vmail mail_uid = 5000 managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave passdb { args = /etc/dovecot/master-users driver = passwd-file master = yes } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap lmtp sieve pop3" service auth-worker { user = $default_internal_user } service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } unix_listener auth-userdb { group = dovecot mode = 0600 user = dovecot } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service managesieve-login { inet_listener sieve { port = 4190 } } ssl_cert = <cert ssl_key = <cert userdb { args = uid=vmail gid=vmail home=/domain/%1d/%d/%1n/%n allow_all_users=yes driver = static } protocol lmtp { postmaster_address = post(a)whatever.com } protocol imap { mail_max_userip_connections = 10 } protocol pop3 { pop3_uidl_format = %v.%u } And the command I am using to (attempt) a mailbox sync: doveadm -o mail_fsync=never backup -R -u alantestuser(a)whatever.com imapc: Produces this output: dsync(alantestuser(a)whatever.com): Error: user alantestuser(a)whatever.com: Couldn't drop privileges: getgrnam(vmail) failed: No such file or directory (in mail_privileged_group setting) dsync(alantestuser(a)whatever.com): Fatal: User init failed mail.log shows this: Dec 5 21:10:54 newmailserver dovecot: auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Dec 5 21:10:54 newmailserver dovecot: auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Dec 5 21:10:54 newmailserver dovecot: auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libauthdb_ldap.so Dec 5 21:10:54 newmailserver dovecot: auth: Debug: passwd-file /etc/dovecot/master-users: Read 1 users in 0 secs Dec 5 21:10:54 newmailserver dovecot: auth: Debug: master in: USER#0111#011alantestuser(a)whatever.com#011service=doveadm Dec 5 21:10:54 newmailserver dovecot: auth: Debug: master out: USER#0111#011alantestuser@whatever.com#011uid=5000#011gid=5000#011home=/domain/w/whatever.com/a/alantestuser I followed this doc (which could use a little fleshing out, I will be happy to do it once I get a grasp on this!): http://wiki2.dovecot.org/Migration/Dsync Thanks in advance! /Alan

[Dovecot] what's wrong with this config file?
by Jim Reid 12 Dec '13

12 Dec '13

Hi. I'm setting up a new IMAPS server. Mail users don't have login access to the box but will each have unique UNIX-style UIDs: no back-end database or LDAP thing. So far. Their mail will get delivered to UNIX-style mailboxes in /var/mail/%u (where %u is the UNIX username obviously). Their IMAP folders will go in /var/imap/%u. These will contain subfolders once everyone migrates to the new set-up and some folders will contain messages and subfolders. I think this is what I configured in dovecot. However when I try to set up a test account, dovecot reports the following error: Dec 12 02:22:00 shaun dovecot: imap-login: Login: user=<jim>, method=CRAM-MD5, rip=10.0.0.1, lip=10.1.1.1, mpid=14874, TLS, session=<8Hy1Ak3t+gDDNulD> Dec 12 02:22:00 shaun dovecot: imap(jim): Error: user jim: Initialization failed: namespace configuration error: Duplicate namespace prefix: "" Dec 12 02:22:00 shaun dovecot: imap(jim): Error: Invalid user settings. Refer to server log for more information. I've checked and re-checked the wiki. google was unable to suggest any explanation either. Any ideas what's wrong?

[Dovecot] ot: tracking messages- luser troubleshooting

I had a user complaining of 'not getting emails' I've searched for sender in maillog, got two messages, both showed up as; Dec 12 15:51:29 emu postfix/pipe[9607]: 3F21C5E750: to=<xxx>, relay=dovecot, delay=6.4, delays=6.3/0.01/0/0.12, dsn=2.0.0, status=sent (delivered via dovecot service) Dec 12 15:51:29 emu postfix/qmgr[20178]: 3F21C5E750: removed yes the user claimed the message was not received, eventually, after traversing through severl directories, I found the message in '../Maildir/.Deleted Messages' it turns out it was inadvertenltly deleted on iphone. there has to be a better way to try to find / resolve such issues ? what's an optimal way of trying to trace such? I greped for the 3F21C5E750 string through several Maildirs tia,

[Dovecot] Dovecot as caching proxy
by Anton Lundin 12 Dec '13

12 Dec '13

Hi. I'm bin playing around with dovecot to try to setup it as a caching imap proxy. I manged to get dovecot to use both proxy=y and imapc: connections to the master server, but i haven't manged to get dovecot to cache any mails. The remote imap server is a quite hostile one, that i don't have any super/master user access to, and it only exposes imap. I've used tried both with the static passdb, nopassword=y, and imap authdb and with static and prefetch userdbs. I manage to produce the same results, eg. dovecot grabbing the password from the client and uses it to establish a imapc connection to the server and re-exposing it, and starts to write indexes. ( The later plan is probably to use pam as passdb to grab a and store a hashed copy of the password to allow offline access to the cached emails, but thats a later problem to solve.) What i haven't managed to get working is to trigger some replication of the remote emails to dovecot and using that as a cache to serve the emails to the client. I found some presentations and some emails that point in the direction that this should be possible to achieve, probably with the replication plugin, but never managed to get this to work. I'm using dovecot 2.2.9 Does anyone have manged to produce a working setup like this? //Anton -- Anton Lundin +46702-161604

[Dovecot] Dovecot connection problem - Too many invalid commands (no auth attempts) - v2.0.19
by Thomas Standaert 12 Dec '13

12 Dec '13

Hello. This might be a silly problem, but I'm a bit a newbie at this, and the internet didn't give me a solution to this yet. I installed a mail server with postfix, dovecot, postfixadmin and a mysql DB for authentification, using this tutorial : <http://www.exratione.com/2012/05/a-mailserver-on-ubuntu-1204-postfix-doveco t-mysql/> http://www.exratione.com/2012/05/a-mailserver-on-ubuntu-1204-postfix-dovecot -mysql/. Except step 4. The complete tutorial worked on a virtual machine, but doesn't work here on a vps from ovh.net. Connecting via telnet localhost 143 works, I can connect. When I try to connect via thunderbird, the domain name is picked up, but gives me a bad login/password combination. Mail.log, mail.err and error don't show anything. Via MS Outlook, I seem to get stuck on the connection page, and I get the following errors in mail.log: dovecot: imap-login: Disconnected: Too many invalid commands (no auth attempts): rip=x, lip=y dovecot: pop3-login: Disconnected (no auth attempts): rip=x, lip=y dovecot: imap-login: Disconnected (no auth attempts): rip=x, lip=y, TLS: Disconnected dovecot: pop3-login: Disconnected (no auth attempts): rip=x, lip=y, TLS: Disconnected dovecot: pop3-login: Aborted login (no auth attempts): rip=x, lip=y dovecot: imap-login: Disconnected (no auth attempts): rip=x, lip=y, TLS: Disconnected dovecot: imap-login: Disconnected (no auth attempts rip=x, lip=y dovecot: imap-login: Disconnected (no auth attempts): rip=x, lip=y, TLS handshaking: Disconnected dovecot: pop3-login: Disconnected (no auth attempts): rip=x, lip=y, TLS handshaking: Disconnected And after a while asks to try to connect via plain method. Doveconf -n gives me this # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-042stab068.8 x86_64 Ubuntu 12.04.2 LTS simfs auth_mechanisms = plain login first_valid_uid = 150 last_valid_uid = 150 mail_gid = mail mail_location = maildir:/var/vmail/%d/%n mail_uid = vmail passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocols = " imap pop3" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = mail mode = 0600 user = vmail } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } Hope you guys can help me, and thanks in advance for it.

[Dovecot] multiple passdbs and auth sockets

Hello, I want to use different authentication arguments for smtp and imap/pop3. In the dovecot list I found this: http://www.dovecot.org/list/dovecot/2013-August/091960.html I tried to follow these instructions but dovecot refuses to find the auth executable: Dec 12 10:36:18 jlaptop postfix/smtpd[7302]: connect from localhost[127.0.0.1] Dec 12 10:36:18 jlaptop dovecot: auth-10: Error: doveconf: Fatal: execvp(/usr/local/var/run/dovecot/dovecot/auth) failed: No such file or directory Dec 12 10:36:18 jlaptop dovecot: master: Error: service(auth-10): command startup failed, throttling for 2 secs Dec 12 10:36:18 jlaptop dovecot: auth-10: Fatal: master: service(auth-10): child 7304 returned error 89 (Fatal failure) Dec 12 10:36:18 jlaptop postfix/smtpd[7302]: fatal: no SASL authentication mechanisms Dec 12 10:36:19 jlaptop postfix/master[7046]: warning: process /usr/lib/postfix/smtpd pid 7302 exit status 1 Dec 12 10:36:19 jlaptop postfix/master[7046]: warning: /usr/lib/postfix/smtpd: bad command startup -- throttling My settings for postfix and dovecot are as follows: root@jlaptop:/usr/local/etc/dovecot/conf.d# postconf -n alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases append_dot_mydomain = no biff = no config_directory = /etc/postfix default_transport = error home_mailbox = Maildir/ inet_interfaces = loopback-only mailbox_command = mailbox_size_limit = 0 myhostname = jlaptop mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 queue_directory = /var/spool/postfix readme_directory = no recipient_delimiter = + relay_transport = error relayhost = smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination smtpd_sasl_auth_enable = yes smtpd_sasl_path = private/auth-10 smtpd_sasl_type = dovecot smtpd_tls_cert_file = /etc/ssl/certs/ssl-cert-snakeoil.pem smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtpd_use_tls = yes virtual_gid_maps = static:8 virtual_mailbox_base = /var/mail/smtp virtual_mailbox_domains = jlaptop.com virtual_mailbox_maps = hash:/etc/postfix/vmaps virtual_minimum_uid = 100 virtual_uid_maps = static:124 root@jlaptop:/usr/local/etc/dovecot/conf.d# doveconf -n # 2.2.9: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 3.11.0-13-generic x86_64 Ubuntu 13.10 auth_debug = yes auth_debug_passwords = yes auth_verbose = yes first_valid_uid = 124 mail_gid = mail mail_home = /var/mail/imap/%n mail_location = maildir:~/mail mail_plugin_dir = /usr/local/lib/dovecot/ mail_plugins = gpgfuse_umount mail_uid = vmail namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = session=yes dovecot driver = pam } protocols = imap pop3 lmtp imap pop3 service auth-10 { executable = auth -c /usr/local/etc/dovecot-auth-smtp.conf process_limit = 1 unix_listener /var/spool/postfix/private/auth-10 { group = postfix mode = 0666 user = postfix } } ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { args = uid=vmail gid=mail home=/var/mail/imap/%n driver = static } The file /usr/local/etc/dovecot-auth-smtp.conf is as follows: auth_mechanisms = plain login disable_plaintext_auth = no #auth_username_format = %Lu auth_debug = yes auth_debug_passwords = yes auth_verbose = yes first_valid_uid = 124 mail_gid = mail mail_uid = vmail protocols = imap pop3 lmtp imap pop3 ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem passdb { driver = pam args = dovecot } userdb { driver = static args = uid=vmail gid=mail home=/var/mail/imap/%n } The result is exactly the same also if I don't give the path to auth. I.e.: executable = auth -c /usr/local/etc/dovecot-auth-smtp.conf In order to get past this problem I provided the auth executable in /usr/local/var/run/dovecot/dovecot/auth, but then I get a new problem: Dec 12 12:31:53 jlaptop postfix/smtpd[9220]: connect from localhost[127.0.0.1] Dec 12 12:31:53 jlaptop dovecot: auth-10: Error: Debug: Loading modules from directory: /usr/local/lib/dovecot/auth Dec 12 12:31:53 jlaptop dovecot: auth-10: Error: Debug: Read auth token secret from /usr/local/var/run/dovecot/auth-token-secret.dat Dec 12 12:32:03 jlaptop postfix/smtpd[9220]: fatal: no SASL authentication mechanisms Dec 12 12:32:04 jlaptop postfix/master[8842]: warning: process /usr/lib/postfix/smtpd pid 9220 exit status 1 Dec 12 12:32:04 jlaptop postfix/master[8842]: warning: /usr/lib/postfix/smtpd: bad command startup -- throttling My test client is thunderbird with smtp connection security "None" and Authentication method "Password, transmitted insecurely". Any ideas what is going wrong? Is there a better way to provide different passdb settings for smtp and imap/pop3? regards, - Jouko
