Re: [Dovecot] repeat downloads of message headers in 1.0rc19
by Jim Garrison 16 Feb '07

I reported this against rc7 and rc8, and still see it occasionally. (I'm running the rc8 that comes with Fedora 5). It is always associated with this message in dovecot.log: dovecot: Oct 23 19:26:17 Error: POP3(user(a)domain.tld): mbox sync: UID inserted in the middle of mailbox /var/mail/vhosts/domain.tld/user (12 > 4, seq=2, idx_msgs=5) Once this happens, dovecot will refuse to clear out the mbox file when the user retrieves email via POP. Each time the user logs in to retrieve mail s/he gets everything in the mbox, which continues to grow. The only fix I've been able to find is to manually delete the mbox file. I'm using postfix as the MTA.

[Dovecot] Proxy with MasterUser + Authentication issues
by Cassidy B. Larson 16 Feb '07

16 Feb '07

Per Timo's direction, I decided to give the MasterUser a try in connecting my proxy to my destination server. This might allow for the use of 'secure password' for my clients that like to check that box by default. A couple of problems I'm running into running RC15: #1: My Proxy's SQL password_query line: password_query = SELECT a.clearpasswd AS password, v.storeIP AS host, CONCAT(v.userID,'*someuser') AS destuser, 'Y' AS nologin, 'Y' AS nodelay, 'Y' AS proxy, 'somepass' AS pass FROM iwmailsystem.virtmailbox AS v NATURAL JOIN authenticate.users AS a WHERE v.userID = '%u' and v.imap_active = 1 I'm wanting to authenticate the user on the proxy before I send it off via the MasterUser to the destination server. However, I show this in the logs: Info: auth(default): client in: AUTH 1 PLAIN service=IMAP lip= x.y.z.a rip=a.b.c.d resp=AGJ1dGNoQGluZm93ZXN0LmNvbQBzZWNyZXQ= Info: auth-worker(default): sql(user(a)host.com,a.b.c.d): query: SELECT a.clearpass wd AS password, v.storeIP AS host, CONCAT(v.userID,'*someuser') AS destuser, 'Y' AS nologin, 'Y' AS nodelay, 'Y' AS p roxy, 'somepass' AS pass FROM iwmailsystem.virtmailbox AS v NATURAL JOIN authenticate.users AS a WHERE v.userID = 'user(a)host.com' and v.imap_active = 1 Error: auth(default): file auth-request.c: line 207 (auth_request_save_cache): assertion failed: (extra_fields == NULL || (strstr(extra_fields, "\tpass=") == NULL && strncmp(extra_fields, "pass=", 5) != 0)) Error: child 54122 (auth) killed with signal 6 The Wiki showed I should return a 'pass' column. However, that's choking the query up in auth-request.c. Could it be the "\tpass" from auth-request.c? If I change user(a)host.com's password to 'someass' and remove the 'pass' column from the password_query, it authenticates, and proxy's over just fine. Am I doing something wrong? I want to authenticate the user locally on the proxy and pass off the 'master password' to the proxy, but using 'pass' doesnt work. 'password' column does. Doesnt help me though for my situation :) Problem #2: I'm wanting to put the masteruser/pass in the database for quick retrieval and updating. So I setup dovecot.conf as: passdb sql { # Path for SQL configuration file, see doc/dovecot-sql.conf for example args = /usr/local/etc/dovecot-sql.conf master=yes #pass=yes } passdb passwd { } and dovecot-sql.conf with: password_query = SELECT '%u' AS user, 'master-password' AS password Trying to connect locally with a "telnet localhost 143" via: 1 login user(a)host.com*someuser "somepass" Give me this in the detail log file: Info: auth(default): client in: AUTH 1 PLAIN service=IMAP lip= a.b.c.d rip=w.x.y.z resp=AGJ1dGNoQGluZm93ZXN0LmNvbSphZG1pbkBpbmZvd2VzdC5jb20AbWFzdGVyLXBhc3N3b3Jk Error: auth-worker(default): BUG: PASSV had invalid passdb ID Warning: Killed with signal 15 I am able to successfully authenticate with the master user/pass if I store it in a passdb file. However, I'd prefer to have it in the database for obvious reasons. Any help to the above would be appreciated. thanks, Cassidy

[Dovecot] Dovecot proxy question (hostname instead of ip)
by Wouter de Jong 16 Feb '07

16 Feb '07

Hello, We are planning to use the Proxy feature of Dovecot, but fail to implement it currently the way we would like to. Reason is that proxy insists to have an IP-address as host : Feb 15 15:43:24 proxy-test.widexs.nl dovecot: pop3-login: proxy(username): mspool01-test.widexs.nl is not a valid IP When I changed the query to force the IP-address of the above server, it works. Would it be possible to make this work, but more important ... Are there any reasons NOT to make this work ? :)) Kind regards, Wouter. -- WideXS http://www.widexs.nl Wouter de Jong System-Administrator Tel +31 (0)23 5698070 Fax +31 (0)23 5698099 Bijlmermeerstraat 62, 2131 HG HOOFDDORP, NL

[Dovecot] domain truncated
by Nemanja Miletic 16 Feb '07

16 Feb '07

Hi all, I have a problem with domain information being truncated from username during ldap search, so it can not be used in mail_location. This happens when user part of the username %n is used in pass_filter in passdb ldap search. When I use %u all username information remains and mailbox can be located. Here is my configuration. In dovecot.conf I have two locations one for system and one for virtual users: ... mail_location = maildir:/var/spool/mail/%n mail_location = maildir:/var/spool/mail/vdom/%d/%n ... Also two configurations for passdb: ... passdb ldap { args = /etc/dovecot-ldap.conf } passdb ldap { args = /etc/dovecot-ldap-virt.conf } ... Here info is searched in ldap: /etc/dovecot-ldap-virt.conf ... base = dc=%d,ou=Virtual Domains,dc=eunet,dc=yu pass_filter = (&(objectClass=posixAccount)(uid=%n)) ... And the line in log file stating that maildir can not be located: mkdir(/var/spool/mail/vdom//cone/cur) failed: Permission denied Is this a bug or I am doing something wrong. Thank You, Nemanja

I'm not sure if this is related or not, but we set mmap_disable=yes last week and since then have seen what appears to be an occasional infinite loops. I have been trying to track down some more details before posting to the list, but here is what I have so far.
