[Dovecot] index file vs. memory
by Marten Lehmann 25 Feb '06

25 Feb '06

Hello, we have a large base of mailbox users and while pop3-connections are usually closed after the download of all mails, I noticed hundrets of imap-connections kept idle by the users. This is surely according to the idea behind imap, but I'm a bit afraid of overwhelming memory consumption if there are too many imap-connections opened at the same time. Is the index file kept in memory as long as an imap-connection exists, or is it closed as soon as a certain read or write command has finished? Regards Marten

Thanks it's the solution. I added to dovecot.conf protocol pop3 { pop3_uidl_format = %08Xv%08Xu }

Hello Timo, What was the reason to remove ssl_parameters_file setting? Is it possible to restore it? We really need it, and I can see no reason to remove this useful setting. -- Sergey Redin

[Dovecot] rpm build problem with beta 3
by Daniel 25 Feb '06

25 Feb '06

Hi I have a small problem with building a rpm of dovecot. I normally build rpms from the tar balls to install on our servers. With beta 3 I'm getting the error below. It builds fine if it is left stock with no ldap support. This the snip from the .spec file I put the --with-ldap as I require ldap support however this is stoping it from building. %configure \ --with-ldap \ --with-ssl="openssl" \ --with-ssldir="%{_sysconfdir}/ssl" I have tested this on Fedora Core 3 and Core 4 both get the same. Output of the end of the 'rpmbuild -tb dovecot-1.0.beta3.tar.gz'. /usr/bin/install -c pop3-login /var/tmp/root-dovecot-1.0.beta3/usr/libexec/dovecot/pop3-login make[3]: Nothing to be done for `install-data-am'. make[3]: Leaving directory `/usr/src/redhat/BUILD/dovecot-1.0.beta3/src/pop3-login' make[2]: Leaving directory `/usr/src/redhat/BUILD/dovecot-1.0.beta3/src/pop3-login' Making install in pop3 make[2]: Entering directory `/usr/src/redhat/BUILD/dovecot-1.0.beta3/src/pop3' make[3]: Entering directory `/usr/src/redhat/BUILD/dovecot-1.0.beta3/src/pop3' test -z "/var/tmp/root-dovecot-1.0.beta3/usr/libexec/dovecot" || mkdir -p -- "/var/tmp/root-dovecot-1.0.beta3/usr/libexec/dovecot" /bin/sh ../../libtool --mode=install /usr/bin/install -c 'pop3' '/var/tmp/root-dovecot-1.0.beta3/usr/libexec/dovecot/pop3' /usr/bin/install -c pop3 /var/tmp/root-dovecot-1.0.beta3/usr/libexec/dovecot/pop3 make[3]: Nothing to be done for `install-data-am'. make[3]: Leaving directory `/usr/src/redhat/BUILD/dovecot-1.0.beta3/src/pop3' make[2]: Leaving directory `/usr/src/redhat/BUILD/dovecot-1.0.beta3/src/pop3' Making install in util make[2]: Entering directory `/usr/src/redhat/BUILD/dovecot-1.0.beta3/src/util' make[3]: Entering directory `/usr/src/redhat/BUILD/dovecot-1.0.beta3/src/util' test -z "/var/tmp/root-dovecot-1.0.beta3/usr/libexec/dovecot" || mkdir -p -- "/var/tmp/root-dovecot-1.0.beta3/usr/libexec/dovecot" /bin/sh ../../libtool --mode=install /usr/bin/install -c 'rawlog' '/var/tmp/root-dovecot-1.0.beta3/usr/libexec/dovecot/rawlog' /usr/bin/install -c rawlog /var/tmp/root-dovecot-1.0.beta3/usr/libexec/dovecot/rawlog /bin/sh ../../libtool --mode=install /usr/bin/install -c 'gdbhelper' '/var/tmp/root-dovecot-1.0.beta3/usr/libexec/dovecot/gdbhelper' /usr/bin/install -c gdbhelper /var/tmp/root-dovecot-1.0.beta3/usr/libexec/dovecot/gdbhelper test -z "/var/tmp/root-dovecot-1.0.beta3/usr/sbin" || mkdir -p -- "/var/tmp/root-dovecot-1.0.beta3/usr/sbin" /bin/sh ../../libtool --mode=install /usr/bin/install -c 'dovecotpw' '/var/tmp/root-dovecot-1.0.beta3/usr/sbin/dovecotpw' /usr/bin/install -c dovecotpw /var/tmp/root-dovecot-1.0.beta3/usr/sbin/dovecotpw make[3]: Nothing to be done for `install-data-am'. make[3]: Leaving directory `/usr/src/redhat/BUILD/dovecot-1.0.beta3/src/util' make[2]: Leaving directory `/usr/src/redhat/BUILD/dovecot-1.0.beta3/src/util' Making install in plugins make[2]: Entering directory `/usr/src/redhat/BUILD/dovecot-1.0.beta3/src/plugins' Making install in convert make[3]: Entering directory `/usr/src/redhat/BUILD/dovecot-1.0.beta3/src/plugins/convert' make[4]: Entering directory `/usr/src/redhat/BUILD/dovecot-1.0.beta3/src/plugins/convert' mkdir -p -- /usr/lib/dovecot/imap /usr/lib/dovecot/pop3 /usr/lib/dovecot/lda for d in imap pop3 lda; do \ rm -f /usr/lib/dovecot/$d/lib02_trash_plugin.so; \ ln -s ../lib01_convert_plugin.so /usr/lib/dovecot/$d; \ done ln: `/usr/lib/dovecot/imap/lib01_convert_plugin.so': File exists ln: `/usr/lib/dovecot/pop3/lib01_convert_plugin.so': File exists ln: `/usr/lib/dovecot/lda/lib01_convert_plugin.so': File exists make[4]: *** [install-exec-local] Error 1 make[4]: Leaving directory `/usr/src/redhat/BUILD/dovecot-1.0.beta3/src/plugins/convert' make[3]: *** [install-am] Error 2 make[3]: Leaving directory `/usr/src/redhat/BUILD/dovecot-1.0.beta3/src/plugins/convert' make[2]: *** [install-recursive] Error 1 make[2]: Leaving directory `/usr/src/redhat/BUILD/dovecot-1.0.beta3/src/plugins' make[1]: *** [install-recursive] Error 1 make[1]: Leaving directory `/usr/src/redhat/BUILD/dovecot-1.0.beta3/src' make: *** [install-recursive] Error 1 error: Bad exit status from /var/tmp/rpm-tmp.30428 (%install) RPM build errors: Bad exit status from /var/tmp/rpm-tmp.30428 (%install)

[Dovecot] Dovecot username mapping
by Adam "Fuzzy" Kennedy 25 Feb '06

25 Feb '06

Ok, here's my situation. I currently run IMail 7.x with about 80 domains and nearly 4000 users. I want to switch this to a Linux server. I'm using Virtualmin to manage the users/postfix. I have dovecot working just peachy with the setup, except for one problem. We are an ISP. The easiest thing for us (and our users) is to have them use their full email address as their username. What I need is some way to have Dovecot take a username and map it to the real unix user. Our unix users are created as "username-domain.com" When our users login to our current email system, they enter their username as "username(a)domain.com". I for the life of me cannot figure out how to make Dovecot take "username(a)domain.com" and know that the unix username is really "username-domain.com" Ideas? -Adam "Fuzzy" Kennedy

RE: [Dovecot] IMAP login name conversion

> -----Original Message----- > From: Timo Sirainen [mailto:tss@iki.fi] > Sent: Tuesday, 1 June 2004 9:39 PM > To: Zoong Pham > Cc: dovecot(a)dovecot.org > Subject: Re: [Dovecot] IMAP login name conversion > > What passdb and userdb do you use? Unless you're authenticating from > SQL you probably have to modify the source. Let me explain: My server runs OpenBSD-3.5 and Sendmail. We host few virtual domains. Local accounts have login names in this format: login-domain_abc_xyz For example: joedirt-joedomain_com_au, info-adomain_com, info-otherdomain_com That way login accounts are unique across all the virtual domains. I use the OpenBSD pre-compiled dovecot-0.99.10p2. It is set to use "auth_passdb = passwd" and "auth_userdb = passwd" I can use mutt to access my mailbox via IMAPS with login name format joedirt-joedomain_com_au. Other users use different MUA like Outlook and prefer to login with their email addresses (joedirt(a)joedomain.com.au, info(a)adomain.com, info(a)otherdomain.com) We use squirrelmail for webmail. I modified squirrelmail to automatically convert login name from format of joedirt(a)joedomain.com.au to joedirt-joedomain_com_au. So if users use squirrelmail, they can just login with their email addresses. My question is how to achieve the same thing with other MUAs like Outlook? Do I have to modify dovecot source? Can I use LDAP or SQL instead? Note that we are using Sendmail and prefer it than othe MTA. I have looked at the Wiki, specially the "DovecotOpenLdap" but am still confused. Thanks Zoong

[Dovecot] Old Maildir UW-imap
by Torbjörn Gripp 24 Feb '06

24 Feb '06

Hi all, I'm new in using dovecot and I'm running in a problem, which I cannot solve without hours and hours of work. Maybe there is a solution, which I didn't find with old friend google :_) Here is the problem: We are using an old mailserver (it's running fine for 5 years) with qmail and the old uw-imap server. All users have their grown directories under a home/Maildir folder. All subdirectories are lying under Maildir/sub/sub/sub. Now I want to migrate to dovecot and I have a lot of trouble, cause I cannot find a solution to migrate to the folder structure /Maildir/.sub.sub.sub. It's really difficult cause all the windows users have subdirs like one folder (1945)/a new ö/ and something like that! Any hints?? greetings and sorry for the bad english -- [ t o r b j o e r n g r i p p ] senior systemadministrator opus 5 interaktive medien gmbh grossneumarkt 50 20459 hamburg fon: +49(0)40 350174-439 fax: +49(0)40 350174-404 mobil: 0175 9326096 mailto:gripp@opus5.de http://www.opus5.de
