[Dovecot] IPv6-enabled dovecot-1.1rc* does not accept IPv4-connections
by Bernhard Schmidt 08 Mar '08

08 Mar '08

Hi, I'm having a really really strange problem. After upgrading from 1.1.beta13 to 1.1.rc2 (happened with rc1 as well IIRC) I can't connect to the services using IPv4 anymore. dovecot happily binds to the IPv6 wildcard socket which should accept IPv4 connections as well. root@vs02:~# netstat -lnp --tcp | grep dovecot tcp6 0 0 :::993 :::* LISTEN 30758/dovecot tcp6 0 0 :::995 :::* LISTEN 30758/dovecot tcp6 0 0 :::110 :::* LISTEN 30758/dovecot tcp6 0 0 :::143 :::* LISTEN 30758/dovecot root@vs02:~# telnet ::1 110 Trying ::1...

[Dovecot] dovecotpw
by Brent Clark 08 Mar '08

08 Mar '08

Hi I would like to simulate dovecot's dovecotpw with a perl script I tried / used use Crypt::SaltedHash; my $csh = Crypt::SaltedHash->new(algorithm => 'SHA-1'); $csh->add($passwd_string); my $salted = $csh->generate; also use Digest::SHA1; use MIME::Base64; $ctx = Digest::SHA1->new; $ctx->add($passwd_string); $ctx->add('salt'); my $salted = '{SSHA}' . encode_base64($ctx->digest . 'salt' ,''); But it doesnt work. Basically what im doing is authenticating against a mysql db. If i do a dovecotpw -s SSHA -p password and update the DB, then the mail client authenticates perfectly. If anyone can help, it would be most appreciated. Kind Regards Brent Clark

[Dovecot] User another userdb to sasl
by Nicolas Letellier 07 Mar '08

07 Mar '08

Hello, I use Dovecot 1.0.12 with Postfix on FreeBSD. It works perfectly, but I have a question. My users are virtual (stocked in a MySQL database). I use SASL Dovecot authentification, and SASL uses my userdb (for POP/IMAP access). However, I would like my users have an other login/password to send email with SMTP/SASL. Or, I don't want my users use the same login/password for POP/IMAP than SMTP. More, I don't want some users could send emails with their login/password, but I want they can fetch their mails. I'm looking for an option in my dovecot.conf to specifie a table SQL for SASL authentification (and don't use same table SQL than IMAP/POP access). How I could do for this problem? Do you have an idea? Or, simply, is it possible with Dovecot SASL? I read all Dovecot wiki, with no results... Thanks very much. Nicolas

[Dovecot] Building Dovecot with OpenLDAP break PAM LDAP on Solaris
by Laurent Blume 07 Mar '08

07 Mar '08

Hi all, I'm back with more data on a problem Iposted about one month ago. To sum it up, my Solaris 10 box has local accounts as well as LDAP ones via PAM. They work well as-is, with no special configuratio, for WU IMAP (using the «other» entry in pam.conf. When I tried a self-built Dovecot, all accounts were authenticated without problem. Then I tried the Blastwave version, same release, but with more option, and this one didn't work with the exact same configuration: local accounts were authenticated, not the PAM LDAP ones. Now, it turns out that when Dovecot is built using OpenLDAP, then PAM LDAP account won't work. If it's built with Solaris LDAP, they work, everything else being equal. Is there any way to fix that? There's the Blastwave bug report with more details if needed: http://www.blastwave.org/mantis/view_bug_page.php?f_id=0002760 Thanks in advance for any help, Laurent -- / Leader de Projet & Communauté | I'm working, but not speaking for \ G11N http://fr.opensolaris.org | Bull Services http://www.bull.com / FOSUG http://guses.org |

[Dovecot] Squat performance
by Timo Sirainen 07 Mar '08

07 Mar '08

The initial building (and an occational compression) performance just got a major boost. I knew there was a problem there, but I hadn't realized it was this easy to fix: http://hg.dovecot.org/dovecot-1.1/rev/4445415da4ff My 1,4 GB test lkml mbox can be now indexed in 7 minutes, doubling the speed form earlier 14 minutes. I added some more benchmark results here: http://wiki.dovecot.org/Plugins/FTS So the initial Squat index building is about 2-3x slower than the non-indexed search. I think that's pretty good. Also I think it means that the non-indexed search code could be optimized more. :) Maildir test shows that it indexes about 5 MB/CPUsec. My earlier tests showed that it indexed 8-10 MB/CPUs when feeding data directly to it, so 3-5 MB/CPUs is going elsewhere, probably to message parsing and charset conversions and such..

[Dovecot] Upgrading from 0.99.10.5 to 1.1
by Anders 07 Mar '08

07 Mar '08

Hi, I am upgrading a setup from Dovecot 0.99 to 1.1. There are a bunch of .imap.index* files that it appears that I can just delete, and they will be recreated as dovecot.index* files. Right? Next, there are some .customflags that I have now learned are not being converted to dovecot-keywords (as we skipped the 1.0 version, and the conversion code appears to be removed in 1.1). Is there some way to convert this? Is it just a rename? Thanks, Anders.
