[Dovecot] Some trouble with dovecot 2.1 and SASL
Hi,
I'm testing dovecot 2.1.0, on Debian 6.0, with "passdb driver = imap"
and SASL for postfix's SMTP-Auth, like explained ih this howto:
http://wiki2.dovecot.org/HowTo/PostfixAndDovecotSASL
Authentications over IMAP (local dovecot -> remote dovecot) works fine,
and it's great. Also smtp-auth on postfix (over SASL) works fine. But in
the dovecot log I found this error:
Feb 19 11:11:42 demo-vpop dovecot: auth: Fatal: master: service(auth):
child 30506 killed with signal 11 (core dumps disabled)
even though all works fine.
This is my dovecot configuration:
# 2.1.0: dovecot.conf-imapc
# OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.4
auth_mechanisms = plain login
default_login_user = nobody
imapc_host = 10.0.0.1
mail_gid = imapproxy
mail_home = /home/imapproxy/%u
mail_location = imapc:~/imapc
mail_uid = imapproxy
passdb {
args = host=10.0.0.1
default_fields = userdb_imapc_user=%u userdb_imapc_password=%w
driver = imap
}
protocols = imap
service auth {
unix_listener /var/spool/postfix/private/auth {
group = postfix
mode = 0660
user = postfix
}
}
ssl = no
userdb {
driver = prefetch
}
But if instead of "unix_listener /var/spool/postfix/private/auth" I
use:
service auth {
unix_listener auth-userdb {
}
inet_listener {
port = 12345
}
}
no errors appears in the log. In both cases all works fine.
Is there any errors in my dovecot's configuration?

[Dovecot] Automatic Debian packages for Dovecot v2.2.
Hi, For our testing enthusiasts I've created new automatic Debian repositories for Dovecot v2.2. Repositories are available for Debian oldstable, stable and testing, on both i386 and am64. Read the following wiki item for more information: http://wiki2.dovecot.org/PrebuiltBinaries#Automatically_Built_Packages The repository for Dovecot v1.2 has been defunct for a few months now and is expected to be removed soon. For the coming month or so, the builders at Xi will not be active during Dutch daytime. There are some issues with the virtual host's I/O performance that need to be resolved first. Regards, Stephan.
[Dovecot] dovecot freezes when trying to get mail from maildir with mail
I'm completely stumped by this problem and I've tried everything at present - including installing dovecot from scratch. The problem is that when trying to get email from the server -AND- there's email in the account, the pop3 or imap process freezes and no email is fetched. The crazy thing is, that it has been working perfectly, but suddenly I'm getting these freezes both when using telnet from localhost, roundcubemail on the same server and Seamonkey from another computer. Logging seems to work perfectly. For an account without email, dovecot finds the maildir++ and acts correctly. For an account -with- email, dovecot seems to find the maildir++, but also seems to try Namespace of which I haven't defined any. I've tried to get rawlog to work also, but that didn't work - the telnet process froze on login even though I'm quite sure I did the right thing and ps showed an active rawlog process Postfix is delivering the email straight into the mailboxes.

[Dovecot] A Postfix/Dovecot example with SQLite backend [crossposted]
There are many mail howtos on the web ... can one more hurt? http://rob0.nodns4.us/howto/README http://rob0.nodns4.us/howto/ http://rob0.nodns4.us/howto/latest.tar.gz (all files) (Sorry, not HTML yet. That is on the agenda.) This is a multiple address class sample implementation of a Postfix MTA and Dovecot IMAP server using a SQLite3 data backend. Domain lookups, user maps, access and transport maps: all using a single, shared SQLite database file. What, other than the SQLite backend, distinguishes this from other mail system howtos? The Postfix high points include a complete implementation of all address classes and per-address transport(5) maps, virtual(8) UID/GID maps, and smtpd(8) recipient access(5) maps. (The latter is using smtpd_restriction_classes, which are not discussed in detail, but are implemented in an interesting way.) On the Dovecot side, it's mostly standard stuff. The SQL deny userdb implementation, and the seamless integration of system and SQL users, might be interesting. I think the database itself is the best part of this example. It's as close to "normalized" as I think it can reasonably be. A significant fact is that each revision of the system has tended to simplify the schema. That's a good sign, I think. One central Domain table lists all domains and hostnames to which the server makes reference. Likewise, a central Address table lists all addresses (with a pointer to the Domain table for each record.) The Alias table defines relationships between Address entries. (Both local(8) and virtual(5) alias maps exist in that table.) Comments and suggestions are welcome, on-list if it's topical to whichever list (please don't crosspost unless comments are relevant to both lists), or offlist to the address in the README file (or as detailed below.) Thanks for your interest. -- http://rob0.nodns4.us/ -- system administration and consulting Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:

Re: [Dovecot] Something is strange - perhaps my AMD processors ?
Hi Julio. I'm not sure what You're asking. Can You specify and I will provide the information. I'm so puzzled since this is easy to install and I have done so before without many issues. I think I'd better get the source and go through it . Cheers, Finn B On 02/18/2012 05:30 PM, Julio C.

[Dovecot] Homedir vs locations vs mail_location?
Hello,
I use Dovecot for rather long time, but I'm still in doubt for some
small things. Here they are:
1. The homedir value points to the place where everything for the user
stored at, while mail_location is something (some place) where mail
stored at. if I deal with pure virtual users (all users are in sql
tables and no system homes for them at all), should I ever care for
returning meaningful value for 'homedir' (via password_query's
userdb_home), or I can simple return empty or constant ('' or '123') for
it and it won't mess anything?
2. If I use single (default) namespace, should I set namespace's
location (to the same value as global mail_location), and should I
expect anything strange if I skip it to set? Reversely, is it possible
not to set global mail_location and set only namespace's location (which
would be more logical as namespace definition is compact and easy to
find in config)?
I've reread my questions and see it is dummy ones, but I'd like to know
that for sure.
Thank you in advance,
Alexander
