[Dovecot] Feature Request - wild idea - folders for executing programs
by Marc Perkel 29 Aug '05

29 Aug '05

Timo, I have a wild idea for a feature that is somewhat unusual, would be very powerful, and easy to implement. What I want is ... Special folders that when someone drags a message into them - it pipes the message into a program. The reason I want this is - for example - reporting of spam. Suppose you want everyone to have a spam-missed folder so that if a spam gets through then the user drags it into the spam missed folder. But instead of storing it there it executes a program and pipes the message into it. In this case a learner program for the spam filter. The folder would be "write only" and attempting to read the folder would generally look like it was empty. Setup would look like this: executable-folder spam-missed { command = /usr/bin/sa-learn spam user = spamd group = spamd create_folder = yes accounts = * } The "create_folder" command says to add the folder to the users lists whether or not it is physically there. The folder appears even if there is no real folder. If it is "no" then it only exists if there is a real folder. The "user" and "group" is of course the UID and GID to run the "command" as. The "accounts" determines which accounts are affected. Default is everyone. Other uses is to control blacklists and whitelists. Dragging a message into the blacklist folder runs an executable that adds the sender to a blacklist, or a whitelist, or controls settings etc.

[Dovecot] Sig11 and some corrupted indexes after 1.0-stable -> 1.0.alpha1
by Ben Beuchler 29 Aug '05

29 Aug '05

I just upgraded my production box from 1.0-stable to 1.0.alpha1. I've noted some new errors in my dovecot logs: Aug 28 23:23:56 cliff dovecot: IMAP(rsferra): Corrupted index cache file /mail/mcad.edu/rsferra/Maildir/.Sent Items/dovecot.index.cache: indexid changed Aug 28 23:33:57 cliff dovecot: IMAP(acarr): Corrupted transaction log file /mail/mcad.edu/acarr/Maildir/.Deleted Messages/dovecot.index.log: unexpected end of file while reading header I'm not too worried about those, as I'm hoping they'll go away once all the indexes have been rebuilt. However, these are a bit more disconcerting: Aug 29 09:07:35 cliff dovecot: child 22484 (imap) killed with signal 11 Aug 29 09:07:36 cliff dovecot: child 22488 (imap) killed with signal 11 I don't see any other errors in the logs around those messages. Platform: Gentoo 2005.1, 2.6.10 SMP kernel, mail stored on XFS file system Any thoughts? -Ben

[Dovecot] IMAP noticeably slower after 1.0-stable -> 1.0.alpha1
by Ben Beuchler 29 Aug '05

29 Aug '05

Not much else to say... All LDAP interaction is noticeably slower, from logging in to moving messages between folders. Configuration options: ./configure --prefix=/usr --host=i686-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --build=i686-pc-linux-gnu --with-ldap --disable-ipv6 --without-pam --with-ssl=openssl --without-vpopmail --sysconfdir=/etc/dovecot -Ben

[Dovecot] Dovecot 1.0 alpha trouble on OS X
by Lars Skovgaard 29 Aug '05

29 Aug '05

Hi all! I've just upgraded dovecot from 0.99 to 1.0 alpha, and it seems to be working perfectly except for a strange problem with one of my imap- users Inbox. Every folder is accessible, including the Inbox. The inbox currently contains five mails. With at least three of these, when they are attempted moved, dovecot crashes immediately with the message "Unable to determine CPSProcessSerNum pid: 12345 name: imap". The destination folder seems to be of no importance. I can copy or move these mails from the command-line, but not from the mail-client. I can, however, open them and read them from the Inbox using Apple Mail or SquirrelMail, as well as from the command- line. I've checked the privileges, and the mails belong to the user and have the appropriate rw-privileges. Any new incoming mail seems to be accessible as expected, and can be moved as desired. I apologize if this has already been discussed, but I've searched the archives without finding anything. Best regards Lars Skovgaard

[Dovecot] MySQL user cant log in
by Marvin Stark 29 Aug '05

29 Aug '05

Hi, I configured dovecot IMAP for MySQL authentification. --- start dovecot.conf --- auth_userdb = mysql /etc/dovecot/dovecot-mysql.conf auth_passdb = mysql /etc/dovecot/dovecot-mysql.conf --- end dovecot.conf --- --- start dovecot-mysql.conf --- db_host = localhost db_port = 3306 db_unix_socket = /var/run/mysqld/mysqld.sock db = users db_user = users db_passwd = xxx db_client_flags = 0 password_query = SELECT password FROM users WHERE userid = '%n' AND active = 'Y' user_query = SELECT home, uid, gid FROM users WHERE userid = '%u' --- end dovecot-mysql.conf -- /var/log/mail.log looks fine: --- start mail.log --- Aug 29 14:40:43 vs6020 dovecot: Dovecot starting up Aug 29 14:40:44 vs6020 dovecot-auth: MySQL: connected to localhost --- end mail.log --- But if i try to log in authentification failed. I added the user test to the database and set the user test in my mail client(evolution) I dont know what it could be.. because connecting to mysql worked fine... best regards, Marvin Stark

[Dovecot] Running pop3 on more than one port
by Andrew Gargan 29 Aug '05

29 Aug '05

Hi All This is possibly a silly question but after reading some of the docs and hunting a bit I could not find an answer. I need to run my pop3 service on both the standard 110 port and another (not really sure which yet) port. My ISP is doing shaping on port 110 destined traffic causing a nightmare with some of my machines pulling only some of their mail then crashing (and no its not anything else it is the ISP). How do I get pop3 of dovecot to bind to two ports? Regards Andrew Gargan Developer Interface Media (PTY) Ltd. Tel: 011 507 3003

[Dovecot] mail directory error solved!
by Micah Stevens 29 Aug '05

29 Aug '05

Hi, I figured out my issue, in my database query for the mail dir, I was grabbing the home column instead of the mail column. Once I changed the name of the column returned it started working. Currently my queries are like such: password_query = SELECT `passwd` FROM users WHERE userid = '%u' and user_query = SELECT concat('/usr/local/virtual/',maildir, '.INBOX') as mail, 101 as uid, 103 as gid FROM users WHERE userid = '%u' My question now is currently I'm saving mail like this: mailroot/domain/user/.INBOX I assume I should be able to save it as: mailroot/domain/user/ the .INBOX is superfluous, is that correct, or will imap want to make directories at the same level at inbox? Thanks, -Micah

[Dovecot] Increase logging?
by Micah Stevens 29 Aug '05

29 Aug '05

Is there a way to increase the log level of the dovecot logs? I'm having a real hard time getting an worthwhile information out of the logs. It would be nice if it would display more of the actions it's taking. Thanks, -Micah
