[Dovecot] Dovecot and duplicates
by Veikko "Wexi" Skurnik 10 Feb '10

Hi I'm having a problem setting up duplicate filtering on my mail server. I've set up the mail server with Postfix and Dovecot with virtual LDAP users, ClamAV virus scanning. The problem is that some of the virtual users use multiple e-mail addresses and postfix delivers emails sent to a user as many times as the user has email address entries in LDAP. I was wondering what would be the smartest way to get rid of these duplicates, they have identical message ID:s and a simple procmail recipe does the trick, however as I'm using dovecots deliver, procmail isn't the answer. Is it possible to use Sieve to do this, I've been googling around *a lot* and haven't found anything that would solve the problem... This is the procmail recipe that succesfully eliminates the duplicates: MAILDIR=/var/vmail :0 Wh: msgid.lock | formail -D 8192 .msgid.cache Or could another solution be to configure postfix to first receive the email, then let procmail do the duplicate filtering, then ClamAV does the virus scan and finally dovecots deliver delivers the message to the virtual user's mailbox? Any help will be greatly appreciated =) Wexi -- * Veikko "Wexi" Skurnik: +358(44)5288338 * * wexi(a)wexin.net Wexi@IRCNet * * Näyttämönkatu 4 B 12 33720 Tampere * * "Kosminen balanssi ei saa järkkyä" *

[Dovecot] Understanding migrateuser.sh

I'm sure it comes from my being a gormless idiot, but whatever is the -UKWS argument immediately after the mb2md.pl invocation? > $MB2MD -UKWS -s "$INBOX" -d "$WORKING" As always, reading the idiom of someone else's scripting is an education. And some of it wouldn't work with native AIX sh/ksh, so changed the functions: > folders_hash() { > local HASH=`find $FOLDERS -type f |sort|(IFS=\ > ;while read file; do ls -l "\$file"; done)` > eval "$1=\"$HASH\"" > } > to: > folders_hash() { > local IFS=\ > local HASH=`find $FOLDERS -type f | sort | \ > while read file > do > ls -l "\$file" > done` > # the escapes are so that $1 gets "$HASH" NOT $HASH > # So the resolution is deferred... > eval "$1=\"$HASH\"" > } I would have wished for a few more comments within the script. -- ==== Once upon a time, the Internet was a friendly, neighbors-helping-neighbors small town, and no one locked their doors. Now it's like an apartment in Bed-Stuy: you need three heavy duty pick-proof locks, one of those braces that goes from the lock to the floor, and bars on the windows.... ==== Stewart Dean, Unix System Admin, Bard College, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

I'm running KDC with all users and passwords, but have to manage clients who doesn't support GSSAPI like mobile phones. Is it possible to dovecot SASL check password in KDC when user sends plain text login? I know this is possible to do with saslauthd from Cyrus but prefer to stick with dovecot SASL.

[Dovecot] Converting layouts
by Luciano Mannucci 09 Feb '10

09 Feb '10

Hello, I'm using dovecot 1.2.10 with mbox format (which implies layout=fs) and I would like to switch to maildir++ layout without changing format in order to implement subfolders for IMAP users. I understand that I should move the INDEX location to avoid some namespace conflict (it would be a good idea anyway: I'll move them on another disc :). Now I have mail_location = mbox:/var/spool/mailboxes/%u:INBOX=/var/spool/mail/%u in my /etc/dovecot.conf. I think it should become somethink like mail_location=mbox:/var/spool/mailboxes/%u:LAYOUT=Maildir++:INBOX=/var/spool/mail/%u:INDEX=/var/dovecot_indexes I'll have to rename folders for IMAP users, right? Is there some script that does just that? Some other needed black magic for .subscriptions? Thanks to all in advance, Luciano. -- /"\ /Via A.

[Dovecot] Problem with created ~/mail directory
by Chris Adams 08 Feb '10

08 Feb '10

If a user doesn't have a ~/mail directory and logs in, the directory is created for them. However, it is created with insecure permissions, 0770 (full group access). The problem is this bit in src/lib-storage/index/mbox/mbox-storage.c: #define CREATE_MODE 0770 /* umask() should limit it more */ The code then uses CREATE_MODE as an argument to mkdir_parents(), but mkdir_parents() overrides the umask setting and forces the requested permissions. There's no way to override this except to change the source code. It looks like the same thing is in dbox-storage.c and cydir-storage.c. This is with Dovecot 1.2.10. -- Chris Adams <cmadams(a)hiwaay.net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.

[Dovecot] Plugin question
by Valery Gorbunov 08 Feb '10

08 Feb '10

Hi All. I am developing plugin for Dovecot. And I needs for read some configuration file at startup and store configuration in application wide variable. As I see the plugin_init() method calls multiple times and allocates plugin's variables each time. Could you suggest better way to store variable in application context. Thank you Valery Gorbunov
