Hi,
I don't know why things suddenly fail but you shouldn't use the cyrus
transport anymore. You should use lmtp as a mailtransport directly. If
your postfix setup isn't somehow exotic you should be able to simply
switch with this config:
mailbox_transport = lmtp:unix:/var/lib/imap/socket/lmtp
Maybe you could give it a try.
