[Dovecot] courier to dovecot
by Grafibit Rendszergazda 08 May '12

08 May '12

Dear All, I know there were many threads on this topic. I was searching the archive and the net also, but did not find a solution on my problem. I hope you can help me. I am migrating from an old server using courier to a new server with dovecot and i can not manage to have the same uids after the migration. After copying the message files from the old server to the new, and executing the script from the wiki page the messages are still re-downloaded by the mail clients. After telnet and logging in to the old server port 110, I got the following on the command *uidl*: 1 UID377-1278276092 2 UID387-1278276092 3 UID394-1278276092 4 UID498-1278276092 5 UID499-1278276092 6 UID564-1278276092 On the new server i set up the *pop3_uidl_format = UID%u-%v* because it seems for me that the old server is using the same uidl format. Either if i execute the /./courier-dovecot-migrate.pl --to-dovecot --recursive --convert /command or i don't the uidls on the new server won't be the same. Both the %u and %v numbers are differ. Please give me any hints how to continue the investigation to have a successful migration.

Re: [Dovecot] Upgrading known problems (2.0 to 2.1) ?
by Timo Sirainen 08 May '12

Yes, that's possible. The IMAP/POP3 servers behind Dovecot director wouldn't even need to be Dovecots at all. Although you really want to use v2.1 director since it has a lot of fixes compared to v2.0.

[Dovecot] Panic in index-sync.c: line 25 on dovecot-1.2.17
by Leon Meßner 07 May '12

07 May '12

Hi, with dovecot-1.2.17 (yes i know it's old) i'm getting the folowing error after doing a system upgrade. May 7 22:04:26 mail dovecot: deliver(elon): Panic: file index-sync.c: line 25 (index_mailbox_set_recent_uid): assertion failed: (seq_range_exists(&ibox->recent_flags, uid)) May 7 22:04:27 mail kernel: pid 79989 (deliver), uid 4873: exited on signal 6 (core dumped) this only happens to one user and only with mail from one mailinglist (this one). Mails do get filtered by sieve. After some delivery attempts the mail finaly gets stored alright in the maildir. May 7 22:23:27 mail dovecot: deliver(elon): sieve: msgid=<assp.047487a390.4FA82AA5.60907 09(a)amfes.com>: stored mail into mailbox 'dovecot' May 7 22:23:27 mail postfix/local[82289]: 7DED511402: to=<elon(a)physik.tu-berlin.de>, orig_to=<l.messner(a)physik.tu-berlin.de>, relay=local, delay=1141, delays=1141/0.01/0/0.26, dsn=2.0.0, status=sent (delivered to command: /usr/local/libexec/dovecot/deliver) May 7 22:23:27 mail postfix/qmgr[1303]: 7DED511402: removed After that a new mail does the same dance (perhaps until the next one to this ML arrives). The maildirs are on NFS and in this case only beeing used with my instance of mutt and two other postfix+dovecot servers which are quite idle. Whats the way to debug this ? Thanks, Leon

[Dovecot] Proxying for some users and having the rest local?
by Dr Josef Karthauser 07 May '12

07 May '12

I'm migrating a load of mailboxes from cyrus to a new dovecot server. What I'd like to do is to switch the DNS to dovecot, and set things up so that all old imap mailboxes are accessed through the dovecot proxy. That way I can migrate them one at a time independent of DNS issues. I've got a load of users specified in mysql, and that configuration works well for local mailboxes. How do I configure things so that I can switch proxy access on and off? What's I've got so far is: password_query = SELECT user, domain, password, "masteruser" as master, "masterpass" as pass, proxy, "remoteimap.server" as host FROM mailboxes \ WHERE user = '%n' AND isMailbox AND active AND domain = '%d' I imagined that I could switch the proxy per user by setting proxy='n' or proxy=null for any users that want to be local, and proxy='y' for any users that I want to forward on to the original server. It doesn't appear to work that way though. Irrespective of the proxy value dovecot appears to try and proxy all users. What am I doing wrong? I can't work it out from the docs, and the source will take quite a bit of studying to get to the bottom of it all. Thanks :), Joe
