[Dovecot] doveadm expunge -A mailbox Trash savedbefore 30d
by Jerrale G 31 Aug '10

31 Aug '10

In the shell: ,doveadm(root): Error: User listing returned failure,doveadm: Error: Failed to iterate through some users In the log: dovecot: auth: Error: sql: Iterate query failed: Table 'mail.users' doesn't exist (using built-in default iterate_query: SELECT username, domain FROM users) Why is dovecot trying to "select username, domain from users" when the "service auth" is setup to "select homedir, maildir, sieve_dir, from MAILBOXES.... the same with the password query except for selecting password from mail.mailboxes. The expire dictionary is EXACTLY like the example you posted in the wiki2. I can't remember whether I posted this thread before or not; I remember writing it two days ago but I'm not sure if I sent it as I can't find it in this "mailing lists" folder. Jerrale G.

[Dovecot] Is there a way to catch mailbox and message flag changes?
by John O'Brien 31 Aug '10

31 Aug '10

Guys, We have been trying to establish if there is a way to get some type of notification from Dovecot when a message is appended to a mailbox or when a message has its flags updated. These are the 2 use cases: A message is appended to the mailbox "/Watch", we want to trigger "processing" of the message immediately it arrives. A message in the "Inbox" has its status changed from Unseen to Seen, we want to trigger some code to indicate the message has been "processed". Regards, John

ive added args = uid=vmail gid=vmail home=/home/MAILBOXES/%u/ mail=/home/MAILBOXES/%u/mail and it work. Im not really sure about the hole LDAP thing :) my conf: uris = ldaps://ldap.example.org:636 dn = cn=dovecot server,ou=people,ou=Server,dc=example,dc=org dnpass = hiddenpw auth_bind = yes ldap_version = 3 base = dc=example,dc=org scope = subtree user_attrs = homeDirectory=home,uid=mail=maildir:/home/%$/mail user_filter = (&(objectClass=gosaMailAccount)(|(mail=%u)(gosaMailAlternateAddress=%u)(uid=%u))) pass_attrs = uid=user,userPassword=password pass_filter = (&(objectClass=gosaMailAccount)(uid=%u)) (yea on 1.2 my home was /home/%uid but that suxx and i want to move it to /home/MAILBOXES/%uid) 1) I have a user that can read the PW so i dont need "auth_bind = yes", right? 2) user_* and pass_* i dont need them anymore cause its always: home=/home/MAILBOXES/%u/ mail=/home/MAILBOXES/%u/mail 2010/8/27 Mihajlin Evgenij <skyworker(a)ooobadm.dp.ua>: > В сообщении от 27 августа 2010 17:32:04 автор spamvoll(a)googlemail.com написал: > >> > log say: >> > dovecot: imap(hpeter): Error: user hpeter: Initialization failed: >> > mail_location not set and autodetection failed: Mail storage >> > autodetection failed with home=/home/MAILBOXES/hpeter/mail > > may be try to set into 10-mail.conf or in namespace private (if you have such) > mail_localtion = ~/Maildir > >

[Dovecot] NTLM authentication does not work
by Alexander Cherniak 31 Aug '10

31 Aug '10

Dear Experts, I configured Samba, Kerberos, etc., can login to my CentOS using ADS account, but missing something in my Dovecot config. Windbind seems to work: [root@aCentOs2 dovecot]# wbinfo -a wAlex%pass plaintext password authentication succeeded challenge/response password authentication succeeded Same is true for ntlm_auth helper: [root@aCentOs2 dovecot]# /usr/bin/ntlm_auth --username=wAlex --password=pass NT_STATUS_OK: Success (0x0) But I couldn't get into Dovecot (with or without auth_use_winbind option): . login wAlex pass . NO [ALERT] Unsupported authentication mechanism. Despite very verbose logging, there no clues there. Bellow's my dovecot -n output: # 2.0.0: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-194.11.1.el5 i686 CentOS release 5.5 (Final) auth_debug = yes auth_debug_passwords = yes auth_master_user_separator = * auth_mechanisms = ntlm auth_use_winbind = yes auth_verbose = yes auth_verbose_passwords = plain debug_log_path = /var/log/Dovecot/dovecot_debug.log disable_plaintext_auth = no info_log_path = /var/log/Dovecot/dovecot_info.log log_path = /var/log/Dovecot/dovecot.log mail_location = maildir:~/Maildir protocols = imap ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { args = uid=vmail gid=vmail home=/home/vmail/%u allow_all_users=yes driver = static } It might be irrelevant, but although the lines "auth_use_winbind = yes" and "auth_winbind_helper_path = /usr/bin/ntlm_auth" are close together in the config file, I cannot see the latter when run dovecot -n. I am quite new to Dovecot and will appreciate any help. Thanks, Alex.

[Dovecot] Possible erroneous "aborted login attempts"
by Jerrale G 31 Aug '10

31 Aug '10

Aug 29 22:51:27 server1 dovecot: imap-login: Aborted login (no auth attempts): rip=(obfuscated), lip=173.50.101.12, TLS Aug 29 22:51:27 server1 dovecot: imap-login: Login: user=........... before most every successful login, the same second of time, dovecot has the above message. This is not a huge problem but our firewall is looking for aborted login attempts, for imap/pop3 (relevant to dovecot) dos attempts and, if many people start having problems of their packets being dropped, we will have to stop looking for the statement or lower security slightly, more attempts over a period of time before filtering. However, thanks to your idle feature, there is less of these messages; so, I don't think we will have a problem. The only client that doesn't have a problem is our php webmail but we don't look in dovecot's log for failed attempts from here; as, it is from the same ip, to dovecot from php, constantly without reference to the user. This has been happening since 1.2.11 with us. We don't use any imap relay but was looking into imapproxy for cacheing speed and preventing advanced ddos attempts, those from users with access.

Hi all, anyone know if it's safe to mix a 1.2 environment with 2.0 servers? Im planning on adding some 2.0 servers for test purposes, but now im wondering if thats going to mess up index files or other files for users selecting the test server and then switching back to our normal servers. Regards, Cor

Re: [Dovecot] dovecot - mac firewall problem
by Patrick Fay 31 Aug '10

31 Aug '10

Hi, Thanks everyone for your help and input. I think perhaps my attempt to be brief and focused in posing my question has led to some confusion about my needs and configuration. I do not have the luxury of being able to segregate the server (postfix and dovecot) from client (GUI, etc) on different machines. I am, as Charles' surmised, using this to aggregate disparate mail streams into a single location, and using dovecot to serve it. Since I must run client-ish applications on this machine, the application firewall is desirable. The anticipated load on this system from the server side is quite light, so the throughput overhead incurred by the application firewall is negligible. The problem appears to be that--for some reason--dovecot identifies itself incorrectly to the application firewall, resulting in the garbage shown in the logs and failure to permit this connection (the firewall is configured to explicitly permit connections for dovecot). I note that other daemons (e.g. postfix, sshd, etc) do not exhibit this defect; the firewall works as expected for every other service I've tried except dovecot. The logs for the firewall appear as: Aug 26 20:43:45 hostname Firewall[55]: Deny ^L connecting from XX.XX.XX.XX:37310 uid = 0 proto=6 Aug 26 20:43:53 hostname Firewall[55]: Deny ^H?^U???^Z connecting from XX.XX.XX.XX:37310 uid = 0 proto=6 Both of these are dovecot hits--but the name is different each time. Also the ?'s aren't really "?" marks; they're trans-ascii characters with high bits set that my mailer doesn't like very much. It really looks like a misdirected pointer or something somewhere, but I'm not familiar enough with the codebase to know where to start looking, or if in fact it is something else that is misconfigured. Any thoughts on how to resolve this? Patrick
