Thanks for the answers Timo,
I understand random redirect is not a good idea but I'm trying to evaluate the damage it can do.
If you do it, you'll most likely see some random index related errors.
But are index related errors recoverable (does dovecot notice and fix it dynamically ?) or will they cause client-side corruption ?
How bad would that corruption be ? (like fetching wrong message, since index store nextuid as well ? setting wrong flag ? ...) and how could a client fix it ?
caches.. So I've added some highly OS-specific code that works most of
the time, but not perfectly. It works best with Linux.
Ouch! I run dovecot on FreeBSD ;-(
imaptest exists now in http://imapwiki.org/ImapTest
Thanks. Sorry I didn't find it. Do you have any suggestion to test specifically nfs corruption chances ?
Actual mail content should be safe. Unless you just happen to get such
a cache file corruption that Dovecot doesn't notice it and sends some
broken headers to IMAP client.
If that happened, with Maildir, the actual content on disk on server wouldn't be corrupted I guess, so I would that be recoverable on the client ?
The long term fix for this is http://www.dovecot.org/list/dovecot/2009-August/041983.html
Thanks.
