Re: [Dovecot] How do I use sieve to move bounces?

How can I use sieve to move bounces and non delivery reports (i.e.
anything with an empty envelope from) to a special mailbox? I placed
this snippet at the start of my sieve script
require [envelope, fileinto];
if envelope :is from {
fileinto INBOX.Reports;
stop;
}
But mails are not moved to the reports mailbox, and they are still
processed by the rest of the script.
To answer my own question, this script seems to work for me:
if header :is Return-Path {

stop;

[Dovecot] alert function, V2
I guess the alert function is not part of the spec, because it appears to be unimplemented in Dovecot, even though most clients implement it. Timo, I would hope this would be easy to implement, and it's functionality that will be valuable to every installation. Here's why. America recently had the tragedy of a shooting rampage on a large university campus (yes, America should do something about the violence and free access to guns in our culture/society). What was worse was that, due to the lack of an emergency notification process, some 20+ people died needlessly. Now all college and university administration are scrambling to set up emergency notification processes. Our first take on this is a massive all-hands mailing list, but a) best case, it would take 15 minutes (and as much as an hour) to get to everybody's mailbox. b) users would have to read through their mail and stumble on the message What's needed is an in-your-face unavoidable alert, and the UWIMAP alert functionality provides this. As I recall, you touch just about anything in your IMAP client and there's a popup message in the middle of the client IMAP window...and it happens repeatedly. We tried it back 3-4 years ago and found it too annoying to use. For this purpose, it's perfect. The wy UWIMAP did it, the presence of the file /etc/imapd.alert triggers it, and the text in that file is transmitted to the client. The message has to be short, a one-liner for a small popup window, but this could be a pointer to a shared system message folder. Of course, DC could sense the activation of the alert in some other fashion that the presence of a file. Ideally, whatever activates the alert function should be able to be turned on remotely; I had in mind to do it using a mail aliases that is a pipe to a executable...

Re: [Dovecot] securing dovecot proxy connections
WJCarpenter wrote: ka per another current thread (o/s tuning for imap), I've installed ka imapproxy, and it supports starttls to the backend imap server. It ka doesn't use encryption on the incoming connections though, since ka they are presumably from localhost (squirrelmail). Ken That's an interesting thought. Have you actually gotten its STARTTLS to work? I tried it a couple days ago with no luck, but maybe I just didn't try hard enough. I had a bit of trouble with it as well. I set it to connect to the dovecot on 993 and listen on 143 locally. That had an odd effect. It connected to dovecot, but failed to LISTEN locally, and nothing was logged about this failure! After trying various other things, I changed the settings to 143 for both and it worked. Then I set force tls = yes, pointed the config options at the bottom of the config file to valid cert,ca,key, etc.. and yes, it works great. tcpdump verifies that it's using TLS now.

DM == Daniel L Miller [EMAIL PROTECTED] writes: DM I did make a discovery - hardcoding the sieve path, without DM variables, e.g. sieve = /var/mail/amfes.com/dmiller/sieve - DM worked! DM Is there a problem using the domain / user variables in the DM configuration file? get_sieve_path() from cmusieve-plugin.c doesn't do % expansions. The result of get_sieve_path() names a file that gets processed. Here's what it does: - look at sieve var - if it is set but empty no sieve processing will occur at all (i.e. sieve_global_path, see below, will _not_ be considered) - if it doesn't begin with a '/' prepend $HOME/ - if it is not set then use ~/.dovecot.sieve (which is equivalent to $HOME/.dovecot.sieve in this case) If the file found above doesn't exist (strictly speaking if stat(2) returns a negative result) use sieve_global_path. If that is not set, for backwards compatibilty, use global_script_path. Note that whatever gets returned by get_sieve_path() is expected to name a _file_ containing sieve statements.

Re: [Dovecot] passdb/userdb args
Thank you - I was thinking perhaps a wrapper script would be necessary.
How do the multiple userdb/passdb sections work? Once a match is found,
does processing stop? Or are multiple matches combined? Does the
userdb static set defaults which could be used for the userdb ldap?

Hi,
I was face with a similar problem a couple of month ago. If I recall

Here is what I did (adapted to your setup. I think)
In my ldap setup I set
pass_attrs = mail=userdb_home
In the main conf file I did
mail_executable = /usr/libexec/dovecot/special.sh
And in special.sh I put
#!/bin/sh
myuser=`echo $HOME|sed s/@.*$//`
domain=`echo $HOME|sed s/^.*@//`
export USER=$HOME
export HOME=/var/mail/${domain}/${myuser}
export MAIL=maildir:${HOME}

Voila!
Make sure that special.sh is where mail_executable says it is And don't
forget to chmod a+x it.
Hope this helps

Re: [Dovecot] Quota bug in deliver?

I do use prefetch, I have an separate query, too. Without that the

Having both statements and prefetch, the quota works fine with IMAP
and deliver when I have no quota line in the plugin section, when I
add the line (see !!MARK!! below), the deliver takes the quota from
that line instead of the database information. IMAP uses the
information from the database all the time, no matter if I have a
quota line in the config.

I discovered something similar. User's quota from the DB was not used
when the user's quota was over the limit of the plugin part.
According to the docs the db quota values should always come first
before the plugin part but it does not.
I think you might be experiencing a bug that Timo recently fixed:

Re: [Dovecot] o/s tuning for imap
On Tuesday, September 4 at 12:16 PM, quoth Ken A: I'm switching from a pop3 only dovecot install to a pop3/imap install and I'm wondering how many connections every 100 'normal' imap users might have/keep open? Mmmm, I usually estimate that most of the time users keep one connection open. Occasionally some clients (like Mail.app with the IDLE plugin) keep two or three open at all times. Then of course, there's occasional bursts where a client may open ten or more connections, though because IMAP is asynchronous that's technically unnecessary unless you're doing it to reduce latency (unlikely), but some clients do it anyway. So I'd leave a max of around 300-500 connections at minimum. I'm wondering if I need to tweak any o/s related things, like time_wait, etc. Any pointers would be greatly appreciated. The thing to keep in mind about IMAP versus POP is that more folks will be keeping things on your server. That means you're going to need more disk space and (particularly if you use a Maildir backend) more inodes, and you're going to want to reexamine your filesystem and mount options. For example, if you haven't already, turn off atime updating. It's entirely useless with Dovecot, and will just slow you down. ~Kyle -- The community which does not protect its humblest and most hated member in the free utterance of his opinions, no matter how false or hateful, is only a gang of slaves.

Re: [Dovecot] Dovecot + Sieve - and passdb/userdb
Thanks to everybody who chipped in. I came up with a workaround that
seems fairly simple - I'm actually worried that it's working too well!
I'm using a pure virtual user setup, storing a minimal amount in LDAP.
The whole mail tree is stored under /var/mail, and it's all owned by
vmail.mail. For purely selfish reasons, I'm doing everything possible
to avoid storing the mail folder in LDAP. So I came up with the following:
Postfix is capable of generating the mail folder path via LDAP
manipulation, and I was working on some wrapper scripts for delivery
agents - but since I've now totally converted to Dovecot's deliver agent
that's immaterial.
passdb ldap, just looking up the password.
userdb static {
args = uid=5000 gid=8 home=/var/mail/%d/%n mail=/var/mail/%d/%n
allow_all_users=yes
}
plugin {
sieve = sieve
}
Deliver + sieve is working great. By setting the sieve variable to
sieve, a non-hidden file, it doesn't appear in the folder list. I
made a similar change to pysieved to use a non-hidden folder - in
combination with avelsieve and squirrelmail I now have a
user-maintainable server-side filter solution. Awesome!
Is there a hidden gotcha I'm missing here? It's doing exactly what I
want!
P.S. what's the nice parameter that can be listed in args?

Not sure here. I only use Active Directory (i.e. LDAP) for authentication.
I remember trying, in vain, to use the static userdb, so I guess (and
expected) the processing to stop on the first match. I am not sure how you
would combine things with the deny=yes setting for example.
