dovecot - Mar 2005 - Troubleshooting help

Somehow, hopefully to be determined, I got my Thunderbird/dovecot
Fedora Core 3 configuration into a real snit, such that I can no
longer access my INBOX.

When Thunderbird tries to get the INBOX content (or get new mail) it
reports "The current command did not succeed.  The mail server
responded: Invalid messageset: -2147483648:*."  Scouring logs and
googling has come up empty.  Now I'm flailing at trying to get to a
state that this problem does not exist.  I'd like to understand how
this situation arose and how to deal with it better if it happens to
any other users on my mail server.

Thanks,

-pmr

mbox or maildir? Probably mbox? Sounds like you received an email with a
very high X-UID header which broke things. Probably easiest way to fix
it would be to delete Dovecot's index files (.imap.index*) and remove
all X-UID headers from your INBOX file:

grep -v '^X-UID: ' inbox > inbox2

Dovecot 0.99.14 version doesn't allow this to happen anymore. I guess
you were using older version?

This raises question for me.  I am running 0.99.11, and would like to
upgrade to a newer version with the latest fixes.  I cannot (easily)
discern from the Dovecot web site which version I should upgrade to in
order to retain compatibility (I use maildir + LDAP, FYI).

My understanding is that 1.0-test introduces some changes that will
require "migration."  Can I safely upgrade to 0.99.14 and preserve my
current production mail spool?  1.0-test?

Thanks,
