Re: doveconf error upon boot up
I've just started getting this error on Gentoo Linux. I've been running dovecot-2.3.2.1 for some time and didn't notice it. I recently updated glibc from 2.26-r7 to 2.27-r6 and dovecot was hanging on startup. Recompiling dovecot fixed the hang, but now I'm seeing the same error message as below.

That works perfectly. Stroller.
Disabling index files?
The wiki says: > Each mailbox has its own separate index files. **If the index files are > disabled**, the same structures are still kept in the memory, except cache > file is disabled completely (because the client probably won't fetch the same > data twice within a connection). [1] I tend to grep my maildirs quite often, and use the output to cp emails to other folders, so it's annoying when the dovecot.index.cache files show up in the results. How do I disable the index files, please? My mail server is hardly loaded, so I don't think it'll be a problem to keep the caching in memory. I can find `mailbox_list_index = no` in /etc/dovecot/conf.d/10-mail.conf but this seems to be enabled by default, and it makes no difference when I enable it explicitly - deleted dovecot.index.cache are recreated when Dovecot is restarted. The setting `mbox_min_index_size` tends to suggests it's only for mbox files, not maildirs? Thanks in advance for any help you can offer, Stroller. [1] https://wiki.dovecot.org/IndexFiles

Migrating maildirs - Courier to Dovecot
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 expect they'll probably end up doing so anyway). I'd like to preserve read/unread status of each message, but can't think of anything else important. It doesn't matter if there's a few hours of downtime, but I thought to use rsync because I figured I copy the maildirs a day or two ahead of time, and then a sync immediately before going live will be quicker. Using imapsync [1] looks pretty good, and I'm happy to use that if it'll be "cleaner" or help Dovecot to create its hierarchy more neatly. It looks like Courier creates a courierimapuiddb, courierimapkeywords and courierimapacl in each folder - can I not just delete these, and hand Dovecot a bunch of maildir directories and files to reindex for itself? There are probably only a few hundred thousand messages on the server, a few GB worth, although some of them are many years old. Some of the messages on the old server have the wrong "received" date on them, having the wrong file creation / modification date on the server's filesystem, having been copied there previously (years ago) without using cp's --archive flag. I've always thought I should one day write a script to fix this, perhaps using mboxgrep. Thanks in advance for any of your thoughts, Stroller.
