[Dovecot] A Dovecot Sieve spam filter question.
by aja-lists＠tni.org 31 Dec '09

31 Dec '09

Hi, I'd like to make a filtering threshold for users to let them deal with spamassassin spam-level starred < 8 themselves, but spam-level starred higher than 8 should be discarded how can one do that with the "anyof" option ? the following doesn't work with a test email with "gtube", which scores > 999 : # require "fileinto"; if header :matches "X-Spam-Level" "\*\*\*\*\*\*" { fileinto "discard"; } and I think it would be nice to have not so many lines in the globalsieverc file. TIA, Regards, Adrian

[Dovecot] Pigeonhole Sieve IMAP flag question
by Julian Cowley 31 Dec '09

31 Dec '09

Hello, Here is a small script that I've been running to test a problem I've been seeing. Shouldn't this result in the mail being delivered to the inbox as a new message (ie. without the \Seen flag)? require "imap4flags"; addflag "\\Seen"; removeflag "\\Seen"; Every message gets delivered to the inbox as though it's already been read. Using Dovecot 1.2.9 and Pigeonhole Sieve 0.1.14.

[Dovecot] Hostname setting defaults
by Timo Sirainen 30 Dec '09

30 Dec '09

Any thoughts about the following? hostname setting currently defaults to system's host name, without the domain part. It's used (in v2.0): - dovecot-lda (new deliver): If -a parameter isn't specified and there's no Envelope-To: header, the destination address is generated as <username>@<hostname setting> - lda/lmtp: In generated Message-Id: headers ("dovecot-stuff@<hostname>") for rejects, vacation, etc. - lda/lmtp: in reject messages as part of MIME boundary, and also in "Reporting-UA: <hostname>; Dovecot mail delivery agent" header. - lmtp: In the protocol, e.g. "220 <hostname> Dovecot ready" or "421 4.4.2 <hostname> Disconnected for inactivity" - lmtp: In added Received: header Seems pretty clear to me that it should be host.domain.org, not just host. So I suppose I'll change that default. The other thing is postmaster_address. That's accidentally been postmaster(a)example.com in dovecot-example.conf and uncommented. So who knows how many installations have their postmaster address set to that.. I'm thinking of just commenting it out in next v1.2 release so admins needs to change that. But for v2.0 maybe there could be a good default for postmaster_address? "postmaster@<hostname setting>" I think? Because it's postmaster(a)host.domain.org instead of postmaster(a)domain.org, it might not be correct in most installations, but I'm thinking that maybe it's safer. Someone trying out Dovecot on testbox.biguni.edu probably doesn't want bounces going to postmaster(a)biguni.edu..

[Dovecot] dovecot-shared
by Frank Cusack 30 Dec '09

30 Dec '09

I'm confused about dovecot-shared. If the file exists, \SEEN flags are NOT shared? So if dovecot-shared exists, flags are actually private. The doc seems clear on this (albeit not worded very well). I only question it because intuitively you would think the opposite. If backwards compatibility is the reason for this reverse behavior, the file should have been named dovecot-private-flags. In fact that's a great name to stick a list of flags (one-per-line) that are private. -frnak

[Dovecot] Issue Authenticating to a new dovecot-postfix installation
by Anthony Nedland 30 Dec '09

30 Dec '09

I have installed dovecot-postfix and postfixadmin on an Ubuntu 9.10 machine. The userdb and passdb are both mysql. If I set up a user in postfixadmin they are able to send. I can successfully telnet into the server remotely by name on 110 and 25. I'm not looking for any authentication encryption/ssl any of that, just POP3/SMTP. When I telnet into 110 I can enter a username with user [username] then when I do pass [password] I get -ERR Authentication failed. I know the user info is correct. When I set up an account in Outlook Express I get "There was a problem logging onto your mail server. Your Password was rejected:" Also saying -ERR Authentication failed.'. (0x800ccc90,0x800ccc92) So basically the same thing. I can attach the tutorial I used in as a .doc if that would help. Anyway, here is my relevant info I think. -- -- -- Version 1.1.11 -------------------------------------------------------------- ---------------------------------------------------------------- ----------------------------------------------------------------- dovecot-sql.conf GREP driver = mysql connect = host=localhost dbname=postfix user=postfix password=password default_pass_scheme = PLAIN user_query = SELECT '/var/vmail/%d/%n' as home, 'maildir:/var/vmail/%d/%n' as mail, 150 AS uis, 8 AS gid, concat(dirsize:storage=',quota) AS quota FROM mailbox WHERE username = '%u' AND active = 1 password_query = SELECT username as user, password, '/var/vmail/%d/%n' as userdb_home,'maildir:/var/vmail/%d/%n' as userdb_mail, 150 as userdb_uid, 8 as userdb_gid FROM mailbox WHERE username = '%u' AND active = 1 -------------------------------------------------------------- ------------------------------------------------------------- ------------------------------------------------------------- root@mail:/etc/dovecot# dovecot -n # 1.1.11: /etc/dovecot/dovecot.conf Error: Error in configuration file /etc/dovecot/dovecot.conf line 1076: Unknown section type (section changed in /etc/dovecot/dovecot.conf at line 1038) Fatal: Invalid configuration in /etc/dovecot/dovecot.conf Starting line 1076---> master { # Master socket provides access to userdb information.

They refer to dovecot.conf though. The config file is clearly dovecot-postfix.conf so I am confused as to why the other matters. I had noticed changes only when I changed dovecot.conf though.

Re: [Dovecot] Retrieve Physical Message Filename
by Tony Rutherford 30 Dec '09

30 Dec '09

Thanks for the reply. I won't be changing any files, or even accessing them, i'll simply be passing the filename along to "another system". I'm not allowed to change this other system or any of its interfaces. The other system has been in place and is "off limits" as far as changes go (I'm told). To make it simple, this other system needs to be notified of any flag changes on emails. So, when we detect a flag change (in our plugin), we need to pass the message filename along to this other system. I hope this makes sense...and again...i'm not justifying the need for it, but I have to play the hand i'm dealt....Tony RutherfordSoftware EngineerBlueTie Inc.arutherford(a)bluetie.com(585) 586-2000 x1040-----Original Message-----From: "Timo Sirainen" [tss(a)iki.fi]Date: 12/29/2009 04:02 PMTo: "Tony Rutherford" CC: dovecot(a)dovecot.orgSubject: Re: [Dovecot] Retrieve Physical Message FilenameOn Tue, 2009-12-29 at 15:50 -0500, Tony Rutherford wrote: > Hi,Using Dovecot 1.2.9 with Maildir and Layout=FS.In a plugin, i'm > overriding "update_flags":void my_mail_update_flags(struct mail > *_mail, enum modify_type modify_type, enum mail_flags flags)For this > email which is having its flags updated, I need to retrieve the > physical filename of the message.

I've looked around, and I'm guessing > it exists, but I don't see it offhand. The problem is that by the time you're trying to access the file, its flags may have already changed, which also means its filename could have changed. So even if you got it, your code would probably randomly fail. What exactly are you going to do with the filename? Maybe you should instead be opening the file with mail_get_stream() and doing something with the fd. This message is intended solely for the individual(s) to whom it is addressed. If you are not the intended recipient, any dissemination or copying is strictly prohibited. If you believe you received this message in error, please notify the sender and delete from your system.

[Dovecot] Using Dovecot deliver with Postfix
by Tobias Lang 30 Dec '09

Hello, while installing Dovecot sieve, I am not able to deliver email for root. The strange thing is, that mails to ordinary users get delivered. And no, I do not use virtual mail, just ordinary unix accounts with an entry to passwd / shadow. Also before switching from Postfix deliver to Dovecot deliver, everything worked fine. Current versions for dovecot and postfix are: dovecot-1.2.8 postfix-2.6.5 Anybody an idea, where I misconfigured something?

Hello, What does this information mean and how is it relevant? I cannot find documentation other than a brief description in dovecot.conf: %t - number of TOP commands %p - number of bytes sent to client as a result of TOP command %r - number of RETR commands %b - number of bytes sent to client as a result of RETR command Thanks in advance, Cliff
