similar to: Migration from Courier to dovecot

Hi all. I am currently gathering information about migration of Maildir/ structures from Courier to Dovecot. What do you think about http://wiki.dovecot.org/Migration/Courier ? For each courier Maildir account I want to use http://www.dovecot.org/tools/courier-dovecot-migrate.pl to produce dovecot-uidlist file mv courierimapsubscribed subscriptions sed sed -i 's/INBOX\.//' subscriptions

Howdy, I've just migrated a couple of servers to Dovecot, and am loving it so far. I thought I'd share the courier2dovecot shell script I whipped together (based on the instructions I found in the wiki.dovecot.org migration how-to), for converting Courier-IMAP maildirs to Dovecot format. It can be downloaded from my home page: http://bendiken.net/scripts/ While the script is rather

Last night we migrated from Courier-IMAP to Dovecot 1.2RC5 and all seems to work fairly well, but I seem to have lost all my mailboxes apart from INBOX. The maildirs are all on the HD in the correct place (/usr/local/virtual/bordo.com.au/jlbrown): mail:jlbrown root# ls -l total 21400 drwxrwxr-x 13 _vmail _postfix 442 Jun 4 00:11 .4D drwxrwxr-x 14 _vmail _postfix 476 Jun

I apologise, because I'm sure this subject has been done to death, but I want to migrate from Courier to Dovecot. I think my main question is whether there's any reason I shouldn't just rsync the maildirs across from the old mail server to the new one? There aren't many clients using this server, so I don't care if clients have to redownload all their messages (in fact, I

I've tested this only with a test user. http://dovecot.org/tools/courier-dovecot-migrate.pl http://wiki.dovecot.org/Migration/Courier # Migrate Courier IMAP (any version) and Courier POP3 (v0.43+) to Dovecot v1.0 # by Timo Sirainen.

Hi, About a week ago I upgraded our reasonably heavily loaded mail servers from a pretty recent courier version to dovecot-1.1rc10. IMAP performance on dovecot is amazing, however POP3 performance is worse than courier :-( I have uploaded some munin graphs taken today to http://linweb.atlas.pipex.net/dovecot/; the dovecot server is handling about 2000 pop logins/sec and 300 imap sessions (but

Hello, For months I have the following configuration in run. Postfix with Mysql and Postfixadmin, Courier Imap + Pop I get a new server and, therefore, would like to change on Dovecot. The installation has also clapped without problems and the configuration has run so far also without defects. If I liked to call away the emails, I always get the announcement Internal Login failure.

Hi, I'm testing migration from courier to courier-0.57.0 to dovecot-imap-1.1.12 on a debian/sid box. When running the migration script, non of the active users' "courierimapsubscribed" and "courierimapuiddb" files seem to be detected: ZENON:~# ./courier-dovecot-migrate.pl --to-dovecot --recursive /home Testing conversion to Dovecot format Finding maildirs under

Hello Gang, I am new to dovecot and the only reason (so far) I would like to use dovecot, and in production with 12k+ users, is the fact that it's supposed to be faster and less of a resource hog. Now, sometimes I am really good at reading the documentations but it sometimes happens that one overlooks something. I did read the migration notes three times! My users are in /etc/passwd and I

Dear friends, My intention is to migrate from Courier-Imap Dovecot 4.4.1 to 1.1.16, the problem is that I've noticed that when creating folders using the Courier does not create the file courierimapsubscribed therefore I doubt if this will bring me problems trying to perform the migration script by courier-dovecot-migrate.pl drwx------ 8 vpopmail vchkpw 4096 Jun 18 16:38 . drwx------

Hi, guys. I've read the information in the Wiki about making dovecot's UID's match Courier's UID's in the POP3 server, so that a UIDL command on either server will return the same UID's for the same group of messages. However, what I've read doesn't match what I'm seeing in Courier. Courier appears to keep the UID numbers for messages that it uses for the POP3

Hi, Currently we support Courier POP and IMAP for all our users (users can use IMAP as well as POP at the same time). We are thinking about moving to Dovecot; but first moving away from Courier IMAP to Dovecot IMAP (and maybe later also move to Dovecot POP). This would create a mixed environment; after some research I have the following questions. To not break POP3 Courier and still be

Hi, I found a problem in the courier conversion script (courier-dovecot-migrate.pl). In some cases, it does not correctly preserve the order of POP3 UIDLs. Consider the following case, when courierpop3dsizelist contains: /2 9000 1327481629 AAA1:2,S 10000 21:1327481629 AAA2:2,S 10000 22:1327481629 AAA3:2,S 10000 23:1327481629 AAA4:2,S 10000 24:1327481629 AAA5:2,S 10000 25:1327481629 BBB11:2,S

hi, I'm getting quite a few of these in the logs of our new dovecot mail server: Aug 20 09:50:03 mail2 dovecot: POP3(vwc406): Couldn't init INBOX: BUG: Unknown internal error Aug 20 09:50:03 mail2 dovecot: POP3(vwc406): Mailbox init failed top=0/0, retr=0/0, del=0/0, size=0 we migrated from courier and other mailboxes work. any idea what the cause might be or how I can fix it?

I have an courier IMAP server running. To get sib dirs working I had to rename them all to begin with a period ".". e.g Maildir Maildir/{cur,new,tmp} Maildir/.account1/{cur,new,tmp} Maildir/.account2/{cur,new,tmp} Maildir/.account3/{cur,new,tmp} etc If I uninstall Courier and install dovecot, will these "period" dirs be seen by default? I am fairly new to this and

Hi there, I've just been experimenting with the latest courier-dovecot-migrate.pl script and I notice that it favours keeping pop3 UIDL ordering rather than IMAP UID preservation. There is this comment (line 312): # POP3 clients may want to get POP3 UIDLs in the same order always. # Preserve the order even if it causes IMAP UIDs to change. Does anyone have details as to which
