[Dovecot] SSL / TLS
by Carlos Williams 30 Jun '09

30 Jun '09

I am running Postfix and Dovecot on my mail server. I am required now to have SSL/TLS on my mail server. I did check and found out that I have a SSL certificate with Verisign issued to my mail servers FQDN. Now my question is when reading the Dovecot Wiki, I noticed it said that it is not common to use SSL but rather TLS on most mail servers. Even though SSL will work, which should I use on my server? We already have a purchased SSL certificate but does that really matter? Should I simply just revoke that certificate & use TLS instead? So when I read this link: http://wiki.dovecot.org/SSL/DovecotConfiguration Is it talking about a actual SSL certificate or TLS? Thanks for any clarification! - Carlos

[Dovecot] Users with large (4GB) inboxes crippling dovecot
by robforrest 30 Jun '09

30 Jun '09

Hi all, I'm new here and would very much appreciate any help you can give me. We are running a rather outdated mail server that until recently has been running beautifully. Under the pretense of "it is ain't broke, don't fix it" it hasn't been updated so is running Fedora Core 4 and dovecot v0.99.14. What is happening is that as users log in (via thunderbird), they are shown the contents of their mailboxes. However, when they try and access a given email, they get no response even if they wait upwards of 10 minutes. I believe that the problem has arisen from their huge inboxes, several users have inboxes in excess of 4GB. Do any of you know how I could split these large mbox files down in to manageable chunks of 1GB? Please be aware that I only have remote access to the server over a modest internet connection. Thanks again for any suggestions.

[Dovecot] Recommended Groupware?
by it-dovecot＠ml.epigenomics.com 29 Jun '09

29 Jun '09

Hi, is there a recommended groupware (email + calendar + address book + syncing with mobile devices) on top of an existing dovecot installation? Most existing commercially supported groupwares come with their own mail storage engine. I would like to keep dovecot as the email storage engine because of the maildir format which greatly helps with backup & restore. Regards -- Robert Sander

[Dovecot] Dovecot Expire doesn't work
by Stef Simoens 29 Jun '09

29 Jun '09

Hello, I'm using dovecot and I want to use the "expire" plugin. However, it doesn't work, i.e. mails do not get deleted. I ran `/usr/sbin/dovecot --exec-mail ext /usr/libexec/dovecot/expire-tool --test` and besides printing Info: stef/Trash: no messages left Info: stef/Spam: no messages left it doesn't do anything (especially not deleting e-mails). Obviously, in stef/Trash and stef/Spam, there are e-mails waiting to be deleted. I'm using dbox as mail storage; and use dbox:/var/mail/%u as mail_location in dovecot.conf. Furthermore, I'm running 1.1.16 on a gentoo PPC system. This is the output from `dovecot -n` # 1.1.16: /etc/dovecot/dovecot.conf # OS: Linux 2.6.29-gentoo-r2 ppc Gentoo Base System release 1.12.11.1 xfs listen: *, [::] ssl_cert_file: /etc/ssl/dovecot/server.pem ssl_key_file: /etc/ssl/dovecot/server.key login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login verbose_proctitle: yes mail_privileged_group: mail mail_location: dbox:/var/mail/%u mail_plugins: expire auth default: verbose: yes debug: yes passdb: driver: pam args: * userdb: driver: passwd socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 plugin: quota: fs:Disk Quota expire: Trash 7 Spam 30 expire_dict: proxy::expire dict: expire: db:/var/lib/dovecot/expire.db A strace on `/usr/sbin/dovecot --exec-mail ext /usr/libexec/dovecot/expire-tool --test` shows the following output: mkdir("/var/mail/root", 0770) = -1 EEXIST (File exists) stat64("/var/mail/root/Trash/dbox-Mails", 0xbfda2708) = -1 ENOENT (No such file or directory) write(2, "Info: stef/Trash: no messages lef"..., 35Info: stef/Trash: no messages left ) = 35 which explains why nothing happens (stat64("/var/mail/root/Trash/dbox-Mails", which is empty, it should not even exist, but it passes by a mkdir), but why does it want to check /var/mail/root and not /var/mail/%u (i.e. why no stat64(/var/mail/stef/Trash/dbox-Mails))? Thanks for your help and kind regards, -- Stef Simoens

[Dovecot] LDAP Plugin fails to build in 1.2.rc7
by Paul Howarth 29 Jun '09

29 Jun '09

Hi, The LDAP Plugin fails to build (it doesn't attempt to build it) in 1.2.rc7 because $have_ldap_plugin is checked before it's assigned in configure.in. Patch attached. This was not a problem in 1.2.rc6 and earlier versions. Cheers, Paul.

[Dovecot] automated email setup and white/blacklists
by Mediawire - Alistair Campion 29 Jun '09

29 Jun '09

We are running a Red Hat Enterprise Linux environment with Dovecot IIMAP, Exim and mySQL 5.0.81, Apache 2.2.11 We are looking for several server side scripts: 1. Create a user account automatically at the completion of our registration process. i.e. username(a)ourdomain.com and existing MD5 password that is associated with his/her user account 2. Add a new user to an existing subscriber email whitelist (add buddy function) 3. Add an existing user to an existing subscriber email blacklist (block buddy function) Our preference is to receive access to a publicly available scripts. Alternatively, to come to a commercial arrangement with a party who has written or who is prepared to write the same.

[Dovecot] sievec error: "fileinto require missing"
by Braden McDaniel 29 Jun '09

29 Jun '09

I'm getting this error when compiling .dovecot.sieve: $ /usr/libexec/dovecot/sievec .dovecot.sieve .dovecot.sievec Info: line 3: fileinto require missing Unable to parse script: script errors: line 3: fileinto require missing .dovecot.sieve just looks like this: $ cat .dovecot.sieve if header :contains ["List-Id"] ["dovecot.dovecot.org"] { fileinto "INBOX.dovecot"; stop; } I'm probably doing something silly; but I don't see how what I've done differs significantly from examples I've found. And googling for "fileinto require missing" just got me to the sievec source code. What might be the problem here? -- Braden McDaniel <braden(a)endoframe.com>
