[Dovecot] Dovecots Deliver being to verbose
by Dominik Schulz 27 Nov '07

27 Nov '07

Hi, I've got dovecot 1.0rc15 running on a Debian etch box toegether with deliver and exim4 backend by a mysql userdb. Everythin is working fine, except that deliver is much to verbose. It prints lots of information, including the password, for every mail delivered to the syslog. The problem here is that I don't wan't the password to be printed to a log somewhere. How can I turn this off? Relevant log entrys below. Best Regards Dominik Example from delivers logfile: deliver(user(a)host.tld): "2007-11-26 19:37:40 "Info: auth input: user(a)host.tld deliver(user(a)host.tld): "2007-11-26 19:37:40 "Info: auth input: user=user(a)host.tld deliver(user(a)host.tld): "2007-11-26 19:37:40 "Info: auth input: password=password deliver(user(a)host.tld): "2007-11-26 19:37:40 "Info: auth input: home=/home/mail/host.tld/user deliver(user(a)host.tld): "2007-11-26 19:37:40 "Info: auth input: uid=8 deliver(user(a)host.tld): "2007-11-26 19:37:40 "Info: auth input: gid=8 deliver(user(a)host.tld): "2007-11-26 19:37:40 "Info: Loading modules from directory: /usr/lib/dovecot/modules/lda deliver(user(a)host.tld): "2007-11-26 19:37:40 "Info: Module loaded: /usr/lib/dovecot/modules/lda/lib90_cmusieve_plugin.so deliver(user(a)host.tld): "2007-11-26 19:37:40 "Info: maildir: data=/home/mail/host.tld/user/Maildir deliver(user(a)host.tld): "2007-11-26 19:37:40 "Info: maildir: root=/home/mail/host.tld/user/Maildir, index=/home/mail/host.tld/user/Maildir, control=, inbox= deliver(user(a)host.tld): "2007-11-26 19:37:40 "Info: cmusieve: Using sieve path: /home/mail/host.tld/user/.dovecot.sieve deliver(user(a)host.tld): "2007-11-26 19:37:42 "Info: msgid=<49403.129.98.4.165.1196102178.squirrel(a)mail.host.com>: saved mail to dovecot Dovecot.conf w/o comments: base_dir = /var/run/dovecot/ protocols = imap imaps pop3 pop3s disable_plaintext_auth = no shutdown_clients = yes log_path = /var/log/dovecot.log log_timestamp = "%Y-%m-%d %H:%M:%S " ssl_disable = no ssl_cert_file = /etc/ssl/certs/cert.crt ssl_key_file = /etc/ssl/certs/key.pem ssl_parameters_regenerate = 168 ssl_cipher_list = ALL:!LOW login_dir = /var/run/dovecot/login login_chroot = yes login_user = dovecot login_process_size = 32 login_process_per_connection = yes login_processes_count = 3 login_max_processes_count = 128 login_max_connections = 256 login_greeting = Mailserver (powered by Dovecot) ready. mail_location = maildir:/home/mail/%d/%n/Maildir namespace private { separator = prefix = location = inbox = yes } mail_extra_groups = mail mail_debug = no first_valid_uid = 8 last_valid_uid = 8 max_mail_processes = 1024 mail_process_size = 256 mail_max_keyword_length = 50 umask = 0077 mbox_read_locks = fcntl mbox_write_locks = dotlock fcntl mbox_dotlock_change_timeout = 120 protocol imap { imap_max_line_length = 65536 login_greeting_capability = yes } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } protocol lda { postmaster_address = postmaster(a)host.tld mail_plugin_dir = /usr/lib/dovecot/modules/lda sendmail_path = /usr/lib/sendmail auth_socket_path = /var/run/dovecot/auth-master mail_plugins = cmusieve } auth_process_size = 256 auth_cache_size = 256 auth_cache_ttl = 3600 auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ auth_verbose = no auth_debug = no auth_debug_passwords = no auth default { mechanisms = plain passdb pam { } passdb sql { args = /etc/dovecot/dovecot-sql.conf } userdb passwd { } userdb prefetch { } userdb sql { args = /etc/dovecot/dovecot-sql.conf } user = root socket listen { master { path = /var/run/dovecot/auth-master mode = 0600 } client { path = /var/run/dovecot/auth-client mode = 0600 user = mail group = mail } } } dict { } plugin { }

[Dovecot] Mailbox is in inconsistent state
by Dion Hollenbeck 27 Nov '07

27 Nov '07

Running on Fedora 7, error happening on both Dovecot 1.05, and now that I upgraded to 1.07, same thing occurs. dovecot -n # 1.0.7: /etc/dovecot.conf login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: passdb: driver: pam userdb: driver: passwd Email client(s): Eudora 7.0.1 on XP and 6.2.x on NT both do the same thing. Protocol: POP3 Symptom: 1 - On Linux, fetchmail is bringing mail down from ISP and running it through SpamAssasin to remove spam. 2 - Still on Linux, I use Pine 4.64 to manually remove any spam or viruses not caught by SA. Exit Pine. 3 - On windoze, with Eurora, check for new mail, "ERR Mailbox is in inconsistent state, please relogin" 4 - Check for new mail second time, works perfectly. 5 - Use Pine again with new mail having arrived, same error occurs. 6 - Do not use Pine in between and error does not occur. I have tried searching the mailing list archives for this error, but it only is mentioned in conjunction with IMAP. Noticed that UIDs of some value can cause the problem. My actual user IDs start with 500, which according to dovecot.conf is the default allowable. I have made no changes to dovecot.conf at all. I also tried looking at the log, but it appears to be a binary (located in /home/<username>/mail/.imap/INBOX/dovecot.index.log) not a readable text file. thanks, dion -- Dion Hollenbeck Email: hollen(a)woodsprite.com Home Page: http://www.woodsprite.com Brewing Page: http://hbd.org/hollen Toys: 98 4Runner, 86 4x4 PU

[Dovecot] File locking problems and duplicate emails with the snarf plugin
by Adrian Barker 26 Nov '07

26 Nov '07

Two weeks ago we switched all our IMAP users (around 25,000) from the Washington IMAP server to Dovecot, and since then there have been several occasions when reading new email just hangs, and duplicate emails appear. We are using the 'snarf' plugin to copy new email to the inbox, and it looks as though the problems are caused by file locking. We have been using the Washington IMAP server for a number of years without any file locking problems, so the underlying file locking mechanism is robust. Has anyone else seen this problem ? Our IMAP servers (5 of them) are a mixture of Sparc Solaris 8 and Solaris 10 machines, and they use NFS to a central mailspool running on AIX. We are using a mixture of Dovecot 1.0.3 and 1.0.5. Any help would be appreciated, as the problem has caused a lot of disruption, but we are reluctant to revert to the Washington IMAP server because of the performance improvements with Dovecot - there has been a reduction of over 60% in NFS accesses to the filestore. dovecot -n gives: # 1.0.3: /usr/local/etc/dovecot.conf base_dir: /var/run/dovecot/ listen: *:143 ssl_listen: *:993 ssl_ca_file: /usr/local/ssl/certs/sureserveredu.pem ssl_cert_file: /usr/local/ssl/certs/imap-server_ucl_ac_uk.crt ssl_key_file: /usr/local/ssl/certs/imap.key ssl_cipher_list: MEDIUM:!LOW disable_plaintext_auth: no login_dir: /var/run/dovecot//login login_executable: /usr/local/libexec/dovecot/imap-login login_user: pp login_process_per_connection: no login_processes_count: 30 max_mail_processes: 1500 first_valid_uid: 200 mail_location: mbox:%h/imap-mail:INBOX=/nfs/rcs/mail-spool/mail/%u mmap_disable: yes mbox_lock_timeout: 55 mbox_dotlock_change_timeout: 50 mail_drop_priv_before_exec: yes mail_executable: /usr/local/sbin/dovecot-login.csh mail_plugins: mbox_snarf mail_plugin_dir: /usr/local/lib/dovecot namespace: type: private separator: / inbox: yes auth default: passdb: driver: pam passdb: driver: passwd userdb: driver: passwd plugin: mbox_snarf: ~/imap-mail/mbox -- Adrian Barker, Internet Technology Section Information Systems University College London, Gower Street, London WC1E 6BT External phone: +44 20 7679 5140, Fax (+44) 20 7388 5406 Internal phone: x 25140 Email: A.Barker(a)ucl.ac.uk

[Dovecot] Some dovecot conf parameters
by Proskurin Kirill 26 Nov '07

26 Nov '07

Hello all! First of all - sorry for my english. :-) Im working now on migration from cyrus to dovecot(v1.07). Everything work`s fine for now, but some parameters at dovecot conf a mystical for me. :-) dovecot-ldap.conf: user_attrs = mail #,homeDirectory,,,, user_filter = (&(objectClass=qmailUser)(mail=%u)) pass_attrs = mail,userPassword=password pass_filter = (&(objectClass=qmailUser)(mail=%u)) What does this parameters mean? Im understand what mean a *_filter, but im do not understand a *_attrs. Yes, im read a http://wiki.dovecot.org/AuthDatabase/LDAP and http://wiki.dovecot.org/PasswordDatabase/ExtraFields But don`t understand it. :-( Ask you for help, or just say what im read this wiki again and again. --- Best regards, Proskurin Kirill

[Dovecot] Ldap Proxy
by Harrison Metzger 26 Nov '07

26 Nov '07

Hello I'm trying to do an ldap proxy but it is not working, it just continues to access the user's mailbox. I was able to do a proxy with a user in a "passwd-file", but not ldap directory. Here is part my "args" file on the passdb ldap stanza: base = dc=example,dc=com auth_bind = yes pass_filter = (&(objectClass=BCMailAccount)(BCMailEnable=true)(BCMailDovecotEnable=true)(uid=%u)(BCMailDovecotProxyHost=*)) pass_attrs = uid=user,proxy,BCMailDovecotProxyHost=host I've turned on auth_verbose, debug, etc and still can't figure out why it wont proxy. Ive tried adding user_attrs (the same as the pass attrs). I've even just put nologin in the pass_attrs but the user is still able to login, its like that field is not being processed.

[Dovecot] upgrade from version 1.0.3 to version 1.0.7
by dhottinger＠harrisonburg.k12.va.us 26 Nov '07

26 Nov '07

Im working on upgrading to dovecot-1.0.7 from version 1.0.3 which I installed using yum. I backed up my init.d stuff so everything still works. However, when I shutdown my old dovecot version and start the new, I get an empty mailbox when logging into mail. My current config for dovecot.conf on version 1.0.3 has this for my mailbox location:mail_location = mbox:~/:INBOX=/var/mail/%u I went from uw-imap to dovecot some months ago and necessary changes to the .mailboxlist to .subscriptions. Is there a different format for version 1.0.7? -- Dwayne Hottinger Network Administrator Harrisonburg City Public Schools "rarely do people communicate, they just take turns talking"

[Dovecot] NFS lock tester
by Timo Sirainen 26 Nov '07

26 Nov '07

Anyone who has NFS, could you test: http://dovecot.org/tmp/locktest.c 1. Compile: gcc locktest.c -o locktest -Wall -g 2. Start in server 1: ./locktest temp1 3. Start in server 2: ./locktest temp2 4. Server 1 might log "unlink() failed" error after starting the second locktest, ignore that. It starts writing something like: 1 successes 12 successes link() succeeded, but link count=1 12 successes What I'd like to know is what OS you use on your NFS clients, what NFS server you use and what errors does it give (errors being those "link() succeeded/failed, but .." messages). I'm getting that "link() succeeded, but link count=1" error with FreeBSD 6.2. So I'd like to know if this is a FreeBSD bug, NFS server bug or a more common NFS problem that I should work around..
