[Dovecot] filtering out LIST cruft?
by Dan Price 17 Feb '07

17 Feb '07

In planning our migration, I've noticed that lots of users have bits of lint in their ~/mail and/or ~/Mail. For example-- for an mbox called "blah" we may see: blah blah.msf (from Thunderbird) .blah.summary (from... I'm not sure, dtmail maybe) .blah_SIMS_index0003 (from our old IMAP server). When the user goes to "subscribe" they are often overloaded with too many items to choose from-- because all of these files are selectable in the UI-- LIST happily returns them. Is there a way to get dovecot to skip over these, by regex? Could it optionally "taste" files to see if they look like mboxes? I looked at the wiki and the source but didn't find anything. In the absence of this feature, I wonder how other sites have handled this? Obviously I can do some cleanup during migration, but I find that those pesky msf files like to come back. -dp -- Daniel Price - Solaris Kernel Engineering - dp(a)eng.sun.com - blogs.sun.com/dp

[Dovecot] severe performance problem (mail cache related?)
by Dan Price 17 Feb '07

17 Feb '07

Hi all, we're having a bad day with email :) I have a user who was complaining of poor performance today when opening mailboxes. Total time to open the box was about 1 minute. Upon truss'ing the imap process during an open, I saw the trace quoted below at the end of the email. As you can see, for each "FETCH" line of response, we were seeing dovecot do a ton of work-- mmaping anon, lots of munmaps(), etc. -- mmap() and munmap() are not free. The stack trace of at least one of the munmaps is captured below, as well-- deep inside of the mail caching code. Then, I moved aside the user's .imap directory, assuming that forcing dovecot to rebuild its indices and caches could help-- and sure enough the user reported that mailbox open times had dropped to 18 seconds. I truss'd that open, briefly, and it was just a ton of preads at high speed. So I don't know why this user was fine for a week, then suddenly hit this. This is a grave concern if I'm going to roll this out from 15 test users to 250 production users. Thanks for your help.

[Dovecot] trash plugin sql
by Robert Schetterer 16 Feb '07

Hi @ll, with dovecot latest following http://wiki.dovecot.org/DovecotLDAPostfixAdminMySQL i have defined plugin { quota = maildir acl = vfile:/etc/dovecot/acls trash = /etc/dovecot/dovecot-trash.conf } Example dovecot-trash.conf file 1 Spam 2 Trash 3 Sent from wiki The Trash plugin. When saving a message would make user go over quota, this plugin automatically deletes the oldest mails from configured mailboxes until the message can be saved within quota limits. this dont work at my setup where quota is coming out of sql is there any trick to solve this? or did i missunderstand something -- Mit freundlichen Gruessen Best Regards Robert Schetterer https://www.schetterer.org Munich/Bavaria/Germany

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

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.

[Dovecot] Wiki to doc/ in tarball
by Timo Sirainen 16 Feb '07

16 Feb '07

So I finally started building a script that does it. Anyone interested in helping with it so that it produces readable output? First step is getting raw wiki pages. I'll do this directly by getting them from the filesystem. You can get them from here: http://dovecot.org/tmp/wikipages.tar.gz Next there's http://dovecot.org/tmp/wiki2txt.pl which is my horrible Perl script that kind of works now to produce almost readable text files. Its current output is in http://dovecot.org/tmp/wikitxt.tar.gz One thing I'm wondering about is how to make the directory layout work. For example there is "UserDatabase" and "UserDatabase/Static" pages. Currently I'm placing the latter into "_UserDatabase/Static" but I don't think that's the best solution. I was thinking about adding some "include" and "exclude" lists. If a page is in excluce list it's skipped. If it's in neither list it prints a warning but still includes it. So this makes it easy to find out the new pages and figure out if they should be included in the documentation.

[Dovecot] Son't have IMAPS

Hi, I've installed dovecot and i'm pretty sure it has SSL support built in. But i don't have IMAPS. I get all sort of errors. Thunderbird tells: "The connection was refused". If i disable imaps, imap works just fine. If i enable it, none of them work. The certificates in /etc/ssl/certs and /etc/ssl/private are the same ? Any help would be appreciated.

[Dovecot] Is it 1.0 yet?
by Marc Perkel 15 Feb '07

15 Feb '07

OK - my last main bug was fixed a few releases ago. I know that there's no end to getting things right but there comes a point when you need to call it done. No one trusts a 1.0 to be perfect but Dovecot is already better that most 2.0 versions of other software. I vote (as if my vote counted) to call it done, declare victory, and move on to 1.01, 1.02 etc. No one is going to trus it till it gets to 1.02 so I say lets bless it and move on.

[Dovecot] 1.0.rc22 released
by Timo Sirainen 15 Feb '07

15 Feb '07

http://dovecot.org/releases/dovecot-1.0.rc22.tar.gz http://dovecot.org/releases/dovecot-1.0.rc22.tar.gz.sig Found another bad bug in rc19 changes. Wonder why my imaptest catched the bug only in CVS HEAD but not in branch_1_0 even though both had it. Anyway, now the imaptest runs nicely for both, and I'm again optimistic that the bug count is low enough for v1.0 to be released soon :) BTW. My previous benchmarks which showed how mmap_disable=yes and fsync_disable=yes give huge performance benefits are pretty XFS-specific. I did some quick tests with ext3 and the differences were quite small with it. I'll probably do another proper run of tests later. + pop3: Commit the transaction even if client didn't QUIT so cached data gets saved. - Fixed another indexing bug in rc19 and later which caused transactions to be skipped in some situations, causing all kinds of problems. - mail_log_max_lines_per_sec was a bit broken and caused crashes with dovecot -a - BSD filesystem quota was counted wrong. Patch by Manuel Bouyer - LIST: If namespace has a prefix and inbox=no, don't list prefix.inbox if it happens to exist when listing for %.

[Dovecot] selective logging
by T. Horsnell 15 Feb '07

15 Feb '07

>From the wiki: log_path = Use this logfile instead of syslog(). /dev/stderr can be used if you want to use stderr for logging (ONLY /dev/stderr - otherwise it is closed). (I dont understand the above references to the use of stderr) info_log_path = For informational messages, use this logfile instead of the default (What exactly is an informational message, and what is the default?) Can I selectively suppress logging like: Feb 5 11:52:15 ls1 imap(iamelel): File isn't in mbox format: /gfg0/iamelel//claudia/ligplot/NQ10/ligplot.bonds Or do I have to turn off logging entirely? Thanks, Terry.

[Dovecot] maildir and the separator for subfolder
by David Bonnafous 15 Feb '07

15 Feb '07

hi, I use dovecot 1.0rc15 with one maildir namespace. I'd like to be able to use '.' in folders and subfolders name. So, I setup the default namespace with separator =':' But, when I create some folders and then subfolders with thunderbird the filename one the server are named with some '.' no ':'... It seems that dovecot always interprets '.' as a separator for folders. Is-it a bug ? yours, -- David Bonnafous Institut de Mathématiques Université Paul Sabatier Toulouse - France
