Upon upgrading from 1.0.2 to 1.1rc4 I see this error for many of our users:
Getting size of message UID=1 failed Couldn't init INBOX: Can't sync mailbox: Messages keep getting expunged
Logging in with IMAP I would see a bunch of messages with no subject or time and blank bodies (usine horde/imp).
Removing dovecot.index.log, dovecot.index.log.2, or dovecot-uidlist fixes the problem for the account (I chose dovecot.index.log). I imagine that forces a rebuild of the indexes. Removing other files in the directory didn't seem to make a difference, including dovecot.index or some arbitrary non-dovecot file.
Is there a more conventional way around this problem?
If you can show me a way to reproduce the problem I can fix it. I've no idea why it could happen constantly.
The main problem anyway is that getting a message's virtual size fails because the message appears to have been expunged. So Dovecot re-synchronizes the mailbox, which should get rid of the expunged messages. But again it fails the same way, so Dovecot gives up and fails with the error message.
