Hi, I am using dovecot-2.1.3 on centos 5.7. Its running fine. I have two systems for mail server one is for backup. Currently I am running rsync daily. But I want to use dsync. I went through all the http://wiki2.dovecot.org/Tools/Dsync and http://blog.dovecot.org/2012/02/dovecot-clustering-with-dsync-based.htmlbut I couldn't understood how to automatize dsync. Can anybody give me any idea ho to do it ? -- * Thanks & Regards * *Jitendra Kumar Bhaskar* Cell:- +91 7306311531 +91 8102997821

Re: [Dovecot] Mail migration troubles

I have a suspicion that, as usual, no one is going to answer my message. Because of the fact that this is a call for help and no-one ever bothers, I 'll just have to re-phrase my question : Here's what I found on the dovecot wiki : imapsync Here's an example of how to run imapsync for a single user: imapsync --syncinternaldates \ --host1 192.168.1.57 --authmech1 LOGIN --user1 leah(a)example.com --password1 secret \ --host2 127.0.0.1 --authmech2 LOGIN --user2 leah(a)example.com --password2 secret It is quite easy to script this for a number of users, assuming you have their passwords. Even if you do not, imapsync also supports logging in as an admin user that has the ability to copy message for sub users, and a variety of other authentication options. Is the above what I need if I migrate mailboxes FROM dovecot TO dovecot ? E.g. in my example, I only copy mailboxes from an old "user(a)domainA.gr" to "user(a)domainB.gr". Is the above all I need ? Is there a native dovecot tool for this or should I just use imapsync ?

[Dovecot] Proxying Authentication on both sides
by Andy Dills 30 Mar '12

30 Mar '12

I've recently set up a director proxy environment on my test servers, with the intention of deploying on our cluster soon. One thing I found confusing in the proxying documentation [1] was the first bit about their being two ways to do the authentication...either you have the proxy forward the auth to the real server for authentication, or you have the proxy authenticate it and then login to the real server with a master password. Well, we use /bin/checkpassword authentication which hooks into a variety of subsytems for various specific customer needs, and sometimes we need to know the username AND password of the user in order to determine their home directory information. So, using a master password (which requires the back-end server not getting the user password) is out. However, when we have the front-end server do a static director proxy, the problem is that authentication failures are logged on the back-end server with a source IP of the proxy, and no authentication failure with the client IP address is logged on the proxy. So, fail2ban (which is a MUST these days, at least for us) will not be able to properly filter out the brute force attackers. My solution was an alternative: I authenticate with our /bin/checkpassword on the proxy, which authenticates the user and only at that point returns the proxy=y nopassword=y switch to proxy the connection and forward the authentication. As a result, we get logs on the proxy for failed attempts, and the full username and password is supplied to the back-end server for proper processing. Food for thought in case anybody else is implementing this. Thanks, Andy [1] http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy --- Andy Dills Xecunet, Inc. www.xecu.net 301-682-9972 ---

[Dovecot] Multiple instances
by Timo Sirainen 30 Mar '12

30 Mar '12

v2.1 now saves the base_dir and instance_name to /var/lib/dovecot/instances when starting up. If you have for example two instances with names "backend" and "proxy", you can then use: doveadm -i proxy proxy list instead of something like: doveadm -c /etc/dovecot-proxy/dovecot.conf proxy list The same -i parameter works for all dovecot programs. I also added a couple of new doveadm commands: # doveadm instance list path name last used running /var/run/dovecot proxy 2012-02-06 21:41:39 yes # doveadm instance remove proxy It would be possible to add commands to start/shutdown some/all instances using doveadm, but is it all that useful? I'd guess people would have their own init.d scripts anyway doing that. Anything else that could be useful related to this?

[Dovecot] IMAP to Maildir Migration preserving UIDs?
by Gedalya 30 Mar '12

30 Mar '12

Hello all, I'm facing the need to migrate from a proprietary IMAP server to Dovecot. The migration must be as smooth and transparent as possible. The mailbox format I would want to use is Maildir++. The storage format used by the current server is unknown, and I don't look forward to trying to reverse-engineer it. This leaves me with the option of reading the mailboxes using IMAP. There are tools like offlineimap or mbsync, and they do store the UID and UIDVALIDITY info. The last piece of the puzzle is a process to properly create the dovecot-uidlist and dovecot-uidvalidity files. So far I wasn't able to find anything on this. Are there any tips? Are there any tools available to do this job, or part of it? In either case I need this done, and I'll have to create whatever I can't find available. If there isn't anything out there that I'm yet to become aware of, then I'm looking at creating something like an offlineimap post-processing routine? Any help would be much appreciated. Gedalya

[Dovecot] Dovecot migration from any IMAP/POP3 server
by Timo Sirainen 30 Mar '12

30 Mar '12

With the latest hg version / upcoming v2.1.4 you can do a perfect migration to Maildir using imapc/pop3c backends: http://wiki2.dovecot.org/Migration/Dsync The main new feature here is the pop3-migration plugin that matches messages from IMAP and POP3 servers together, so that when dsync needs to request POP3 UIDL for some IMAP message it's actually looked up from the POP3 server.

[Dovecot] newbie: keep getting same emails in mail client
by neuronetv 30 Mar '12

30 Mar '12

dovecot-2.0.9-2.el6_1.1.i686 I've just set up dovecot in centos 6.2 (server install) and finally got it working (kind of). I set up a unix user (not a virtual user) sent a test email to this user but in my mail client I keep getting this test email over and over again. I don't think the fault is with the email client because other emails work fine and never duplicate and I've tweaked the account settings too, so it must be something I've done wrong in the dovecot setup. Here is my dovecot.conf file: # Dovecot configuration file protocols = pop3 imap disable_plaintext_auth = no mail_location = mbox:~/mail:INBOX=/var/spool/mail/unix-username ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem passdb { driver = pam } userdb { driver = passwd } thanks for any pointers. -- View this message in context: http://old.nabble.com/newbie%3A-keep-getting-same-emails-in-mail-client-tp3… Sent from the Dovecot mailing list archive at Nabble.com.
