[Dovecot] migration from IMAP/POP3 courier server to a remote dovecot server

Dear all i'm planning a transparent migration from a courier server that provides both IMAP and POP3 access to users to a remote dovecot server with both IMAP and POP3 access. I have to migrate about 2500 users for 250 GB of space. I'm using dovecot 2.2.5.4 on debian6 squeeze. To make a transparent migration i have to maintain old IMAP UIDs and POP3 UIDs, so i've read http://wiki2.dovecot.org/Migration and http://wiki2.dovecot.org/Migration/Courier and http://wiki2.dovecot.org/Migration/Dsync And decided that probably the best tool to use is Dsync, as the courier-dovecot-migrate.pl<http://www.dovecot.org/tools/courier-dovecot-migrate.pl> script works only locally. I've tested the dsync following instructions reported above but after the migration of one test-account the client re-download messages. If i want to keep both IMAP UIDs and POP3 UIDs i have to sync both imapc and pop3c with two commands? doveadm -o imapc_user=foo -o pop3c_user=foo -o imapc_password=bar -o pop3c_password=bar backup -R -u user@domain imapc: doveadm -o imapc_user=foo -o pop3c_user=foo -o imapc_password=bar -o pop3c_password=bar backup -R -u user@domain pop3c: Or imapc is enough? Do you have any suggestion? Thanks -- /*************/ nik600 http://www.kumbe.it

[Dovecot] Getting back into Dovecot 2.2.5

Hi there, I'm prompted to get into running my own mail server again with Gmail going bad. However I found /usr/share/doc/dovecot/example-config/conf.d/ a little scary, since I like to have my configs as minimalistic as possible, e.g. http://dabase.com/blog/Minimal_squid3_proxy_configuration/ So far I have: https://github.com/Webconverger/sg.webconverger.com/blob/master/dovecot/dov… I was kinda hoping for a Maildir, but this doesn't work: mail_location = maildir:~/Maildir:LAYOUT=fs:INBOX=/var/mail/%u I do realise /var/mail/%u is a mbox, but I was wondering if there could be some clever conversion. I was surprised something like INBOX=/var/mail/%u wasn't the default btw. Also surprised dovecot seems to choke on single line syntax like `passdb { driver = pam }` :-) Next thing I'm confused about is the `namespace inbox {` stuff. Is it really needed? I was expecting Dovecot to create the folders once I defined them, but mutt couldn't see them until I created them myself. The mail server is just for myself and a few colleagues. We will probably use mutt as our MUA and Apple Mail on IOS when we are out & about. I next plan to integrate dspam, and work out how to sort mails into folders like I previously effectively had with Gmail's labels. I was confused to which mechanism I should be using to sort mail into folders with rules. Sieve? Back to Procmail? Pigeonhole? I'm looking to avoid complexity here. On the topic of search, can I get away with not running a Solr server? Since I shudder at the thought of running Tomcat. http://wiki2.dovecot.org/Plugins/FTS Kiitos paljon for any pointers!
