[Dovecot] Disconnects with proxies
by Michael Kress 20 Jan '07

20 Jan '07

Hi, I know I shouldn't ask stuff like this when using dovecot-0.99.11-4.EL4 (CentOS-4.4), but why I'm asking this is whether it's worth to switch from rpm based upstream dovecot to a self compiled one or not and thus I think you wouldn't kill me presenting you this question. o:-) I've got a problem with dovecot regarding a pop3 proxy issue. When I configure my dovecot server to do just plain pop3 I can telnet from a windows box without any flaw, but as soon as the client uses some pop3 proxy (for example outlook uses avira antivir Mail-AntiVirus Protection), queries to that server fail. A log line looks like this: pop3-login: Dec 05 22:53:24 Info: Disconnected [::ffff:84.165.54.42] Moreover with the proxy activated, a telnet to port 110 (pop3) is not working properly, the cursor stays right behind "+OK dovecot ready." and as soon as I enter a character, the server rejects this character as an unknown command (Without pressing ENTER). As soon as I turn off the Antivir-Proxy the telnet to port 110 runs flawlessly and I can login. So I'd like to know is there anything I can do with this version or is it worth trying the newest version? Is this a known issue? Thanks in advance Michael -- Michael Kress, kress(a)hal.saar.de http://www.michael-kress.de / http://kress.net P E N G U I N S A R E C O O L

[Dovecot] Bug Report: ACL plugin searches wrong directory with shared folders
by Garret Huntress 19 Jan '07

19 Jan '07

I've been attempting to get to get Shared Folders and ACL's to work under dovecot 1.0rc17. Unfortunately, I've run into some problems (many have already been mentioned on the list), specifically the problem where folder-specific ACL files are not found (and I will not use Global ACL's due to the 100% probability of cross-namespace mailbox name conflicts). My namespace is as follows: namespace private { separator = / prefix = location = maildir:%h/Maildir inbox = yes } namespace private { separator = / prefix = CIW Archived/ location = maildir:%h/Mailarchive } namespace public { separator = / prefix = CIW Groups/ location = maildir:/srv/export/groups:CONTROL=%h/Maildir/public- subscriptions:INDEX=%h/Maildir/public-index } I decided to run a quick strace on dovecot's imap daemon while I was getting a folder listing to see why dovecot was not finding the folder-specific ACLs. Below are what I feel are the two key instances in the trace: Example 1: searching for ACL on private folder open("/etc/dovecot-acls//.DEFAULT", O_RDONLY) = -1 ENOENT (No such file or directory) open("/home/ghuntress/Maildir/./dovecot-acl", O_RDONLY) = -1 ENOENT (No such file or directory) open("/etc/dovecot-acls/Work", O_RDONLY) = -1 ENOENT (No such file or directory) open("/home/ghuntress/Maildir/.Work/dovecot-acl", O_RDONLY) = -1 ENOENT (No such file or directory) stat("/etc/dovecot-acls/", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0 open("/etc/dovecot-acls/", O_RDONLY) = 7 That looks good. The ACL plugin looking for the global acls first in the correct location, then in the maildir itself for the folder- specific acl. Example 2: searching for ACL on shared folder open("/etc/dovecot-acls//.DEFAULT", O_RDONLY) = -1 ENOENT (No such file or directory) open("/home/ghuntress/Maildir/public-subscriptions/./dovecot-acl", O_RDONLY) = -1 ENOENT (No such file or directory) open("/etc/dovecot-acls/IS.Postmaster", O_RDONLY) = -1 ENOENT (No such file or directory) open("/home/ghuntress/Maildir/public-subscriptions/.IS.Postmaster/ dovecot-acl", O_RDONLY) = -1 ENOENT (No such file or directory) stat("/etc/dovecot-acls/", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0 open("/etc/dovecot-acls/", O_RDONLY) = 7 Not so good. The ACL plugin is looking under the "CONTROL=" setting from the namespace location configuration, and not under the maildir itself for the folder-specific acl. Since we have to set the separate CONTROL location because of subscription conflicts (http:// wiki.dovecot.org/SharedFolders) we either break subscriptions by removing the CONTROL setting, or break ACL's by adding it. I'm not terribly familiar with the inner workings of Dovecot, however I can envision two possible fixes: 1.) Always have the ACL plugin look under the maildir location (and not the CONTROL override) for folder-specific ACLs or 2.) Have dovecot always place subscriptions for shared folders in a user-specific directory regardless of the namespace location configuration (although, this would probably break a ton of production configurations). I don't know what either of the above options would break, but I hope it's gives some ideas on how to fix this long-standing bug. Please let me know if I can be of any more help. -Garret -- Garret W.

[Dovecot] quota in mysql not being updated
by Marshal Newrock 19 Jan '07

19 Jan '07

I'm having trouble getting the quota plugin to work with deliver. The quota in the database is not getting set. I am using dovecot-1.0-rc15. This server is not yet in production. Some values below are because I'm trying to test with the simplest possible case, and some because it's reading from a different database. Also, I noticed that "dovecot -n" doesn't display any information for the lda, nor any plugin information. Entries from /etc/dovecot/dovecot.conf: protocol lda { ... mail_plugins = quota } auth default { .... userdb sql { args = /etc/dovecot/dovecot-sql.conf } } dict { quotadict = mysql:/etc/dovecot/dict-quota.conf } plugin { quota = dict:storage=1024000: proxy::quotadict } from dovecot-sql.conf: user_query = SELECT 225 as uid, 225 as gid, mailbox_path as home, mailbox_path as mail, 'dirsize:storage=10240:messages=1000' as quota FROM transports WHERE email = '%u' dict-quota.conf: connect = ... table = quota_used select_field = quota_used_kb where_field = quota_type username_field = username_and_realm in mysql: describe quota_used; +--------------------+--------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +--------------------+--------------+------+-----+---------+-------+ | username_and_realm | varchar(255) | NO | PRI | | | | quota_type | varchar(255) | NO | PRI | | | | quota_used_kb | int(11) | NO | | 0 | | +--------------------+--------------+------+-----+---------+-------+ mail logs: Jan 7 22:13:46 sentinel deliver(test.marshal(a)acd.net): auth input: test.marshal(a)acd.net Jan 7 22:13:46 sentinel deliver(test.marshal(a)acd.net): auth input: uid=225 Jan 7 22:13:46 sentinel deliver(test.marshal(a)acd.net): auth input: gid=225 Jan 7 22:13:46 sentinel deliver(test.marshal(a)acd.net): auth input: home=/var/mail/vmail01/00/00000001 Jan 7 22:13:46 sentinel deliver(test.marshal(a)acd.net): auth input: mail=/var/mail/vmail01/00/00000001 Jan 7 22:13:46 sentinel deliver(test.marshal(a)acd.net): auth input: quota=maildir:storage=1048576 Jan 7 22:13:46 sentinel deliver(test.marshal(a)acd.net): Loading modules from directory: /usr/lib/dovecot/lda Jan 7 22:13:46 sentinel deliver(test.marshal(a)acd.net): Module loaded: /usr/lib/dovecot/lda/lib01_quota_plugin.so Jan 7 22:13:46 sentinel deliver(test.marshal(a)acd.net): maildir: data=/var/mail/vmail01/00/00000001 Jan 7 22:13:46 sentinel deliver(test.marshal(a)acd.net): maildir: root=/var/mail/vmail01/00/00000001, index=/var/mail/vmail01/00/00000001, control=, inbox= Jan 7 22:13:46 sentinel deliver(test.marshal(a)acd.net): msgid=<20070107221155.0db93ce6@localhost>: saved mail to INBOX -- Marshal Newrock Ideal Solution, LLC - http://www.idealso.com

[Dovecot] Authorization client connect failing
by Ryan Hinton 19 Jan '07

19 Jan '07

Hello, and thank you in advance for your valuable time. I am running Dovecot v1.0.rc15 on an OpenBSD 3.9 i386 machine (no time to upgrade yet). I downloaded the source from the dovecot site, compiled and installed without any problem. The server starts up find and runs for a while. After a few hours to a few days, the server stops sending the CAPABILITY statement when a client tries to login. I found a few descriptions of this problem on the web, but no satisfactory resolution. I added some debugging code to the functions in auth-client.c and got the following traces. Included in this email are a successful login attempt, a failed attempt, and a startup trace. I am not a UNIX sockets guru and don't know the dovecot internals well enough to figure out what's wrong. I am happy to add/remove debugging code as requested to help track down the problem, although it may take a few days for the server to hang again. I hope someone can help me figure out the problem so my mail server works reliably! Here is a successful login attempt. Dec 9 10:34:45 myhost dovecot: imap-login: DEBUG:: auth_client_is_connected?

[Dovecot] Connection to server time out when deleting (moving to Trash)
by Anders Lund 19 Jan '07

19 Jan '07

Hi, Running: * Dovecot 1.0 rc15 * Debian Sarge Linux Using Maildir and IMAP over SSL. When trying to delete a lot of mail (> 5000-6000 messages) in some folder, using Mozilla Thunderbird (1.5.0.7) on Ubuntu, I often experience "Connection to server <hostname> timed out." Any suggestions on how to fix this problem? "Empty Trash" seem to work fine, so I guess this is related to moving a lot of mail from one folder to another (Thrash)? - Anders -- Anders Lund <Anders.Lund(a)uninett.no> .~.

[Dovecot] Virtual Users and Local Users Authentication
by craig carriere 19 Jan '07

19 Jan '07

I am using dovecot on a SLES 10 mail server using postfix as the MTA. The original setup used local users and a single domain. I have now configured postfix to send mail to a second virtual domain which is working fine. I am trying to get dovecot to pick up the mail and have been having authentication problems. My local users uses pam and /etc/passwd for login with SSL. I have created a passwd file for the virtual users and have set dovecot to look at the passwd-like file with the path specified. However dovecot complains about the file not being present, which it is and my local users can not login. Probably doing something simple incorrectly, but can not find what fron online searches.
